Nylon was developed by Carothers, an outstanding American scientist, and a research team under his leadership. It is the first synthetic fiber in the world. The emergence of nylon has given textiles a new look. Its synthesis is a major breakthrough in the synthetic fiber industry and a very important milestone in polymer chemistry. In 1935, a polymer was made from adipic acid and hexamethylenediamine. Since both components contain 6 carbon atoms, it was called polymer 66 at the time. He melted the polymer and squeezed it out through an injection needle, and stretched it under tension to call it fiber. This fiber is polyamide 66 fiber. After industrialization in 1939, it was named Nylon. It is the earliest synthetic fiber variety to achieve industrialization. English name: Polyamide6 or Nylon6, referred to as PA6; Nylon 6, also known as polyamide 6, is polycaprolactam, which is obtained by ring-opening polycondensation of caprolactam. It is a translucent or opaque milky white resin with excellent mechanical properties, stiffness, toughness, wear resistance and mechanical shock absorption, good insulation and chemical resistance. Widely used in automotive parts, electronic and electrical parts and other fields. English name: Polyamide66 or Nylon6; PA66 for short; Nylon 66, also known as polyamide 66, is polyhexamethylene adipamide. Compared with nylon 6, its mechanical strength, stiffness, heat resistance, wear resistance, and creep resistance are better, but its impact strength and mechanical shock absorption performance are reduced. It is widely used in automobiles, drones, electronic and electrical, etc.

Nylon "6" chips are polymer compounds made from caprolactam as raw material, adding a certain amount of additives, polymerizing under certain process conditions, and going through processes such as tape injection, pelletizing, extraction and vacuum drying. Nylon 6 slices (nylon 6 slices) are sheet-shaped granulated products obtained by using the pelletizing method due to their low melt strength in nylon production. The product is colorless, transparent, cylindrical particles with no mechanical impurities and uniform particle size.          Regarding physical properties: polyamide 6 slices, commonly known as nylon 6 slices and nylon 6 slices. Because the macromolecule contains amide bonds (-CO-NH-), it is called polyamide. Nylon 6 slices are usually in the form of white cylindrical particles, with a melting point of 210-220°C and a decomposition temperature of about 300°C. Soluble in phenol and hot concentrated sulfuric acid, it has excellent electrical insulation properties, good alkali resistance and corrosion resistance.   The slices made from nylon as raw material are nylon slices. Such as polyamide 6 slices, commonly known as nylon 6 slices and nylon 6 slices. Nylon 6 slices are usually in the form of white cylindrical particles, with a melting point of 210-220°C and a decomposition temperature of about 300°C. Soluble in phenol and hot concentrated sulfuric acid, it has excellent electrical insulation properties, good alkali resistance and corrosion resistance. Nylon is a fiber with the best wear resistance among synthetic fibers.          The production of nylon 6 slices adopts two-end polymerization, continuous extraction, connected drying and DCS distribution system control. The product is colorless, transparent, cylindrical particles with no mechanical impurities and uniform particle size. Nylon 6 slices are corrosion-resistant and wear-resistant, soluble in phenol and hot concentrated sulfuric acid, have reliable electrical insulation properties, and have good alkali and corrosion resistance.

The temperature resistance range of nylon is generally between -40℃ and 120℃. Different types of nylon materials have different temperature resistance properties. The following is a detailed introduction: 1. Nylon 6 (Nylon 6) and nylon 66 (Nylon 66), their maximum operating temperatures are usually 80°C and 120°C respectively. 2. Urethane nylon (PA6T) and polyamide 11 (PA11). These materials have higher temperature resistance, and the maximum operating temperature can reach about 150℃ and 170℃. 3. Glass fiber reinforced nylon (GFN) and carbon fiber reinforced nylon (CFN). These reinforced nylon materials have very high strength and rigidity, as well as excellent durability. Chemical resistance and high temperature resistance. Under normal use conditions, their temperature resistance range can reach -40℃ to 150℃.    Nylon is a common synthetic fiber with excellent resistance to abrasion, chemicals, and heat. The temperature resistance range of nylon refers to the temperature range it can withstand. This range depends on the type and use of nylon. Generally speaking, the temperature resistance range of nylon is between 60℃ and 120℃. Among them, nylon 6 and nylon 66 are the two most common nylons, and their temperature resistance ranges are respectively 80℃ to 100℃ and 120℃ to 150℃. In addition, there are some special nylons, such as nylon 11 and nylon 12, whose temperature resistance range can reach more than 200℃. The temperature range of nylon is very important for its application. In high temperature environments, nylon will soften, deform or even melt, affecting its performance and service life. therefore, When selecting nylon materials, its temperature resistance range needs to be determined based on specific usage conditions.

As the global economy develops and technology advances, the demand for polyamide 6 chips is expected to continue to grow. Polyamide 6 chips have excellent wear resistance, high temperature resistance and chemical stability, and are widely used in automotive parts, electronic products, aerospace and other fields. As these industries continue to develop and expand, the demand for polyamide 6 chips will continue to increase. At the same time, as environmental awareness increases, the demand for recyclable materials is also increasing. As a recyclable material, polyamide 6 chips will be favored by more markets. Therefore, the demand for polyamide 6 chips in the future market will show a steady growth trend.

The domestic carbon fiber industry has experienced a long cold winter, but in the past three years since the outbreak of the global new crown epidemic, it has ushered in spring unexpectedly. In 2022, under the background of sluggish demand in the textile downstream market, severe overall chemical fiber market conditions, prices running at low levels throughout the year, an obvious lack of industry operating rates, and heavy pressure on corporate profits, domestic carbon fiber continues to perform a unique "drama." Although some carbon fiber companies briefly suspended production in the first half of the year, and poor logistics in many places also intermittently affected the shipments of many companies, the price of large tows this year has declined to a certain extent based on the high level last year. However, in the face of the hot market , these small twists and turns seem not worth mentioning. This year, the production lines were basically running at full capacity, product production and sales were booming and even supply exceeded demand, companies generally made "a lot of money", and multiple new projects were racing against time to meet the deadline... This is the "main theme" of the domestic carbon fiber industry. Stable supply of small tows to major areas Aerospace has always been the dominant application area of carbon fiber, and the products used are small tows. Directed supply orders to major customers in the aerospace field are the "ballast stone" and "stabilizer" that enable my country's carbon fiber industry to maintain stable operation every year. Weihai Guangwei Composite Materials Co., Ltd. (hereinafter referred to as "Guangwei Composite Materials") is my country's main supplier of carbon fiber for national defense and military industry. At the end of last year, Guangwei Composite Materials signed a 10-quarter shaped fiber sales contract totaling 2.098 billion yuan, with the contract period from January 2022 to the end of June 2024. Wang Yingchao, Secretary of the Board of Directors of Guangwei Composite Materials, said that sales contracts for shaped fibers have always been one of the company's main sources of income. The company began executing the contract this year, and the contract execution rate in the first three quarters totaled 32.25%. In the first three quarters of this year, Guangwei Composite Materials achieved operating income of approximately 1.94 billion yuan, a year-on-year decrease of 1.17%; net profit attributable to shareholders of listed companies was approximately 750 million yuan, a year-on-year increase of 21.36%. "During the year, the new crown epidemic caused the company's five business segments to suspend production for more than half a month; the company's shipments to Beijing and Shanghai were affected, which affected the company's revenue and profits to a certain extent." Wang Yingchao said. In the past two years, the price of styling fiber products in the aviation application market has dropped. Li Taoyang, chief analyst of the military industry and new materials sector of CITIC Securities Co., Ltd., said that the carbon fiber materials used in Guangwei composite materials and main model equipment will see their first price reduction in 2021 since they were mass-produced. In the two-and-a-half-year contract, the price of the product was reduced again. "As many types of equipment products in our country enter the mass production stage, price reductions for batch-produced supporting materials are a trend." "In addition to ensuring the supply of shaped fibers, the application space of the company's series of high-performance fibers continues to expand, and the business scale continues to expand. Since last year, T800H grade, M40J/M55J grade, T700S/T800S grade and other carbon fiber products have become the company's new additions The main source of profits." Wang Yingchao further introduced, "This year, a high-performance carbon fiber of the company also passed the installation review, allowing the company to add a new type of fiber to support an important machine on the basis of the existing traditional stereotyped fiber for batch delivery applications. The supply of shaped fibers for type aviation equipment will gradually increase in the future. The company has become a supplier of a full range of carbon fibers for my country`s existing important aviation equipment." "The continuous diversification of products and businesses, as well as the continuous high investment in R&D and the cultivation and development of business, are the solid foundation for the steady development of the company's performance." Wang Yingchao said. Zhongjian Technology Co., Ltd. (hereinafter referred to as "Zhongjian Technology") is a batch and stable supplier of ZT7 series carbon fiber products in my country's aerospace field. In March this year, Zhongjian Technology signed a major sales contract with a contract amount of 2.169 billion yuan and a contract execution period from 2022 to 2023. At the same time, at the beginning of this year, the production capacity of its 1,000-ton production line was officially released. The surge in order amounts and the release of new production line capacity have caused Zhongjian Technology's carbon fiber sales to increase significantly this year. In the first three quarters, the company's revenue was 519 million yuan, a year-on-year increase of 72.8%; the attributable net profit was 320 million yuan, a year-on-year increase of 120.84%. "The company's carbon fiber has been closely following the volume increase cycle of key models, which has been clearly reflected this year." said Li Jianfeng, Secretary of the Board of Directors of Zhongjian Technology. Regarding the current overall application of domestic carbon fiber in the aerospace field, Wang Wenyi, general manager of Guangwei Composite Materials, pointed out: "Domestic carbon fiber is currently mainly used in wind turbine blades and sports and leisure fields, and the combined usage in the two fields accounts for about 70% of the total annual usage. ; The usage proportion in the aerospace field is only 3%. In comparison, the application proportion of carbon fiber in the aerospace field in developed countries is much higher. Next, the application space of domestic carbon fiber in the aerospace field is still huge. Therefore , everyone must work together to further expand the 'cake' of these two markets, and Guangwei will continue to firmly seize these two key high-end application markets." The high-end civilian market for small tows is in short supply This year, high-end small tow carbon fibers such as T700 and T800 are in short supply in the civilian field. "There is a prominent phenomenon in the carbon fiber industry this year. There are many new companies entering and new production capacity. Everyone will worry that when these new production capacities are put into production one after another, will the total production capacity increase again? In fact, the specific situation needs to be analyzed in detail." An industry insider who did not want to be named said, "From a product perspective, the competitive pressure on T700 and above products this year is relatively low, because the technical threshold of such products is relatively high and it is difficult to achieve simple and rapid replication. And the newly invested projects The main purpose is to expand the production capacity of large tows, and the production capacity can be copied quickly and on a large scale. In terms of price, the prices of high-performance carbon fibers such as T700 and T800 are relatively stable this year, basically in the range of 220 yuan/kg to 240 yuan/kg. ." The products of Zhongfu Shenying Carbon Fiber Co., Ltd. (hereinafter referred to as "Zhongfu Shenying") are currently mainly T700 and T800 grades. This year, the production capacity of Zhongfu Shenying Carbon Fiber Xining Co., Ltd. (hereinafter referred to as the "Xining Project") has been steadily released, and the scale effect has accelerated, driving a substantial increase in the overall production and sales of its products. In the first three quarters, Zhongfu Shenying achieved operating income of 1.452 billion yuan, a year-on-year increase of 106.12%; attributable net profit was 424 million yuan, a year-on-year increase of 112.09%. In the past few years, especially before the Xining project was put into operation, Zhongfu Shenying`s carbon fiber was in serious short supply. "A friend once called me and said that someone asked him for help to buy a few tons of carbon fiber, but there was nothing we could do. The company did not have the goods." Jin Liang, secretary of the board of directors of Zhongfu Shenying, said, "Since the Xining project was put into operation, the company's carbon fiber supply The tense situation has been alleviated to a certain extent. Even so, the company's carbon fiber as a whole this year is still in a state of being produced and sold." The annual carbon fiber production capacity of Zhongfu Shenying's Lianyungang base is approximately 3,500 tons, and has been at full production and sales this year; the Xining project's first-phase high-performance carbon fiber annual production capacity is 10,000 tons, and is basically at full production this year. "Since the Xining project was put into operation last year, part of the production line has produced 12K products and another part of the production line has produced 24K products. As of the end of November this year, it has produced and supplied more than 8,000 tons of carbon fiber." Jin Liang introduced. Due to the COVID-19 epidemic, Lianyungang implemented temporary static management for a period of time this year. For more than ten days, the entire Zhongfu Shenying factory implemented closed management and closed-loop production. At the same time, from September to November, Xining`s logistics was also affected to some extent. "Although trucks can enter and exit normally, there is a relative lag. In response, some appropriate adjustments have been made to the raw material stocking and finished product inventory of the Xining project. Under normal circumstances, the company's raw material inventory is 30 days to 40 days, but adjustments will be made in the second half of the year It`s more than 60 days," Jin Liang said. In terms of price, the price of Zhongfu Shenying series carbon fiber is stable this year. Jin Liang said: "The company has established a customer management system. When facing different types of customers, the actual supply prices will have some subtle differences. For example, strategic customers with long cooperation time and large purchase quantities will have a slight advantage in price. But Regardless of the type of customer, our product prices are relatively stable, and each model of product has a minimum shipping price set by the internal management system." It is worth noting that Zhongfu Shenying`s diversified and personalized small tow products are also in short supply this year. Jin Liang introduced that this year the company has made some adjustments to the production capacity of the Lianyungang base. Based on downstream demand, the company converted a production line that originally produced 12K products into products that produce smaller tows. Due to different tows, the overall output of this line has dropped a lot after the switch, but the gross profit margin of the product is much higher, making a greater contribution to profits. "Actually, the company already had two small lines producing products with smaller tows last year. We found that the actual market demand was greater than the production capacity at that time, and the supply of products exceeded demand, so we decided to switch to one production line this year. Throughout this year, products with smaller tows The output is expected to double compared to last year, and these products are mainly used downstream to produce some functional products, such as electronic products, automotive interiors, etc." Jin Liang further explained: [When the Xining project is not put into production, the company`s Lianyungang base must ensure that it meets the strategic and forward-looking production needs. The core idea is to protect the market and supply. Some small batch and diversified needs will be difficult to meet. After the Xining project was put into operation, this situation changed. Since the Xining project was put into operation, it has always produced several core varieties in accordance with the idea of large-scale and mass production, such as 12K and 24K T700 and T800 products. On this basis, the company this year Develop ideas at the Lianyungang base and focus more on small tow, multi-variety, and high-margin carbon fiber products. Among them, there are many types of products with smaller tows; more products with higher performance have also been produced. For example, M series. Now, no matter what kind of small tow products are needed by downstream customers, we can produce them. At present, carbon fiber can be applied to aerospace, pressure vessels, carbon/carbon composites, sports and leisure, transportation construction, wind power and other fields. Our products basically cover all fields." Guangwei Composite Materials` high-performance products such as T700S and T800S are also in short supply this year. Their civil applications include pressure vessels, building reinforcements, gas cylinders, photovoltaic thermal power plants, etc. The reporter learned that the products of Guangwei Composite Baotou Project have been adjusted this year according to market conditions. After the first phase of the project is put into production, it will mainly produce 12K and 24K T700S, T800S and T1000. Wang Wenyi said: "The products we supply in these fields have always been in short supply. According to current customer intentions, even including the 4,000 tons of production capacity after the first phase of the Baotou project is put into operation, it is still not enough." Large tow production and sales are booming but cooling down "Looking back on last year, domestically produced large tow carbon fiber was 'hard to find'. Even customers with large purchases or strategic cooperation often couldn't get the goods from manufacturers, and the manufacturer's quotation was always rising. Due to the actual purchase The price has increased a lot compared to the agreed price, and the raw material costs of some companies have increased a lot last year." An industry insider said with emotion. This year, the large-tow carbon fiber market is still in a state of booming production and sales, and manufacturing companies are still making "a lot of money." Jilin Carbon Valley Carbon Fiber Co., Ltd. (hereinafter referred to as "Jilin Carbon Valley") achieved operating income of 1.519 billion yuan in the first three quarters, a year-on-year increase of 110.01%; attributable net profit was 484 million yuan, a year-on-year increase of 170.1%. Last year, its main business revenue was 1.209 billion yuan, a year-on-year increase of 104.14%; the attributable net profit was 315 million yuan, a year-on-year increase of 126.09%. In 2020, its net profit is still in the red, with a loss of 30.0477 million yuan. Jilin Carbon Valley said that this year the company's products have expanded applications in the industrial and civilian markets, and sales of raw silk have increased. As the new large tow products are gradually finalized, the quality of new and old products continues to improve, the company's main products are booming in production and sales, and the average sales price has increased year-on-year, supporting the growth of net profit. The core driving force for this booming market of both production and sales still comes from the demand support of the wind turbine blade market. The current application fields of large tow carbon fibers such as 24K, 25K, and 48K are mainly wind power carbon beams. Aosheng Composite Materials Technology Co., Ltd., located in Suzhou, Jiangsu, specializes in carbon fiber wind power pultruded panels and is a "big player" in carbon fiber applications. Xu Wenqian, general manager of Aosheng Technology, told reporters that the company's carbon fiber usage in 2021 will be more than 10,000 tons, and this year's usage will be approximately 12,000 tons. However, it is worth noting that the large tow market has cooled down this year under the general market situation where production and sales are still booming. From the perspective of supply and demand, represented by Jilin Chemical Fiber Group, a batch of new domestic production capacities have been rapidly released, and market supply has increased significantly, which has greatly alleviated the serious shortage of supply last year. Data from Jilin Chemical Fiber Group shows that from the beginning of this year to mid-December, the group has newly put into production 4 raw yarn lines and 6 carbonization lines. By the beginning of next year, it is expected that 2 more raw yarn lines and 2 carbonization lines will be completed and put into operation. This will bring its annual production capacity of raw silk to 160,000 tons and carbon filament to 49,000 tons. "This year, domestic large tow production capacity has expanded rapidly, and the domestic market supply is still sufficient." Xu Wenqian said. Due to changes in supply and demand, the price of large tows showed a downward trend from the beginning of the year to the end of the year. As of mid-November this year, the average price of large-tow carbon fiber in my country was 129 yuan/kg, down about 12% from the beginning of the year. "In the last two months of the year, the price of large tows dropped to the range of 105 yuan/kg to 115 yuan/kg; in mid-December, the quotation of large tows even dropped to 100 yuan/kg." An industry insider said. It is also worth noting that on the one hand, my country's large tow production capacity is rapidly expanding, and on the other hand, downstream users still partially use imported products. Moreover, the price of imported large tow products has also declined this year. "In the company's total carbon fiber usage this year, domestic and imported products account for about half each. We mainly import 48K and 50K products. The price of imported large tows is similar to that of domestic products." Xu Wenqian said, "We do this to diversify Raw material procurement risks." In addition, because the overall price of carbon fiber is still high, some downstream users use glass fiber as a substitute in order to reduce costs. This has also become a reason for the cooling of the large tow market. "Considering the high price of carbon fiber, we used about 150,000 tons of glass fiber this year, and also used the pultrusion process to produce wind power girders. These wind power girders are mainly sold to domestic customers." Xu Wenqian said. "Glass fiber is also occupying part of the market with its price advantage. Some composite material companies are developing the use of carbon fiber and glass fiber mixed thermosetting and thermoplastic pultrusion processes to produce wind power beams. Compared with carbon beams, the mixed process is more cost-effective It has certain advantages and will create certain competition in the carbon fiber market." said the above-mentioned industry insider. "The situation of 'price competition' in my country's large-tow carbon fiber market may have begun." A senior practitioner in the carbon fiber industry told reporters.

Its excellent physical properties, chemical stability and environmentally friendly properties make it ideal for making high-quality, durable textiles. With the continuous advancement and innovation of technology, it is believed that the application of nylon 6 chips in the textile industry will be further expanded.

In recent years, nylon 6 chips have attracted widespread attention as a sustainable material. Nylon 6 chips are fiber chips made from regenerated nylon 6 material, which have the same properties and uses as traditional nylon 6, but are more environmentally friendly and recyclable. Recently, a leading nylon 6 chip manufacturer announced the launch of a new nylon 6 chip product made from 100% recycled nylon 6 material. This innovation means that virgin nylon 6 materials no longer need to be used, reducing reliance on limited resources while also reducing negative environmental impact. This new nylon 6 chip product is equivalent in performance to traditional nylon 6 chips and can be widely used in automobiles, textiles, household products and other fields. Compared with traditional nylon 6 chips, this regenerated nylon 6 chip has a lower carbon footprint and higher sustainability, so it is sought after by many businesses and consumers. According to the manufacturer, the regenerated nylon 6 material they use comes from the recycling and reprocessing of discarded nylon products. Through advanced recycling technology, they are able to convert these wastes into high-quality regenerated nylon 6 chips, achieving effective utilization and recycling of resources. This innovation is of great significance in promoting sustainable development and increasing environmental awareness. As a widely used material, the production process of nylon 6 chips usually generates a large amount of waste and emissions. By using recycled nylon 6 materials, the need for virgin materials can be reduced, environmental pollution reduced, and the service life of resources extended. With the increasing awareness of sustainable development, more and more companies and consumers are paying attention to and choosing to use sustainable materials. Recycled materials from nylon 6 chips are one of the innovative solutions to meet this need. It is expected that with the continuous advancement of technology and the promotion of the market, regenerated nylon 6 slices will be more widely used and promoted in the future.

Nylon (Nylon) is polyamide, also known as nylon and nylon. The English name Polyamide refers to a type of linear polymer whose main chain contains repeated amide groups (-NHCO-). Nylon is a white crystalline or translucent thermoplastic resin with elasticity, excellent tensile strength, wear resistance, high mechanical strength and oil resistance. Nylon PA6 is an important member of the nylon family. The nylon industry has a huge family, and the main varieties include nylon PA6, nylon PA66, nylon PA610, nylon PA11, and nylon PA12. Among them, nylon PA6 and nylon PA66 are the most used, accounting for about 90% of the total consumption of nylon. As one of the most important products of nylon materials, nylon PA6 has also been widely used. It is an important application material in the fields of electronics, military, railways, automobiles, textiles, and agricultural accessories. In addition to the traditional nylon fiber field, the application of functional fibers Gradually expanding, and showing a trend of expanding to engineering plastics and film manufacturing, nylon PA6 has gradually become one of the important materials for replacing wood with plastic, steel with plastic, and porcelain with plastic.

There is no difference between nylon 66 and nylon 6 in appearance. From the perspective of performance and physical indicators: nylon has better strength, wear resistance and hand feel than polyester, acrylic, polypropylene and other synthetic fibers, but nylon 66 is stronger than nylon 6. , better wear resistance, more delicate feel. structural difference PA6 is obtained by ring-opening polymerization of caprolactam, while PA66 is obtained by condensation polymerization of hexamethylenediamine and adipic acid. The two have the same molecular formula, but the structure is quite different. The number of hydrogen bonds of PA66 is higher than that of PA6, and the molecular force is also stronger than that of PA6, so PA66 has better thermal properties and requires higher processing temperature. PA6 has better toughness, and PA66 has better rigidity and hardness, which is also caused by the different hydrogen bonds in the molecular structure. performance difference Nylon PA66 Common nylon is a crystalline polymer. The melting point of nylon 66 reported by different grades and different test methods is between 250-271°C, the glass transition temperature (dry state) is 50°C, and the density is 1.13~1.16 grams per cubic centimeter. Because the phthalamide group in the amorphous part of nylon 66 is easy to combine with water molecules, the water absorption rate of nylon 66 is relatively high at room temperature. PA6 is a translucent or opaque milky white crystalline polymer particle with a melting point of 220°C, a thermal decomposition temperature greater than 310°C, a relative density of 1.14, and a water absorption rate (24 hours in 23°C water) of 1.8%. It has excellent wear resistance and self-lubrication High mechanical strength, heat resistance, good electrical insulation performance, excellent low temperature performance, self-extinguishing, good chemical resistance, especially excellent oil resistance. Compared with PA66, PA6 is easy to process and shape, the surface gloss of the product is good, and the service temperature range is wider, but the water absorption rate is higher and the dimensional stability is poor. It has low rigidity, low melting point, can be used for a long time in harsh environments, and can still maintain sufficient stress in a wide temperature range, and the continuous use temperature is 105°C. application difference PA6 is used in industrial fields such as electronics and automobiles. Its civilian silk industry consumes a relatively high proportion of nylon filament for clothing, about 58%. The use of PA6 in the tire frame nylon cord market accounts for about 13%. Engineering plastics use PA6 accounted for 12%, including injection plastics and modified plastics. PA6 accounts for about 6% of fishing net wire. Plastic film-grade PA6 for the production of BOPA film accounts for 4%, staple fiber PA6 for the production of carpets, sweaters, non-woven fabrics and other supplies accounts for 4%, and other PA6 for the production of PA rods, PA tapes, etc. accounts for 3%. PA66 is widely used in clothing, decoration, engineering plastics and other fields. The highest proportion of its consumption is engineering plastics, accounting for 65% of the total consumption, while industrial yarn accounts for 20%, and others account for 15% of the total consumption. Compared with nylon 6, nylon 66 has better mechanical strength, stiffness, heat resistance and wear resistance, and better creep resistance, but its impact strength and mechanical shock absorption performance are reduced. It has a wide range of applications in automobiles, drones, electronics, etc. The development of nylon 66 and nylon 6 should be fully considered from the rational use of resources. When the resources of sulfuric acid are sufficient, the application of ammonium sulfate has its market, and nylon 6 has its own advantages of priority development. It is more appropriate to develop nylon 66 in places where sulfuric acid resources are relatively scarce.

Plastic, one of the greatest inventions of mankind, imagines how difficult and expensive our life would be without plastic. Plastic is actually a general term for man-made plastic chemical products. In the big family of plastics, nylon is the earliest chemical synthetic fiber product. After the birth of nylon, it completely changed people's habit of using fabrics, allowing clothing and fashion to evolve in various forms, and practical and beautiful clothing also flew into the homes of ordinary people. In our impression today, flexible nylon is the darling of the women's world, but in fact its application in military and industry has also set off a storm of the times. In 1928, DuPont of the United States hired young Harvard scientist Wallace Hume Carothers (Wallace Hume Carothers) to lead a research and development team to create an organic polymer to replace natural silk. On February 28, 1935, they synthesized polyamide polymer compound. After countless attempts, Carothers finally chose to develop this polyamide polymer compound. Carothers named it "polyamide 66" (the first 6 represents the number of carbon atoms in the diamine, and the second 6 represents the number of carbon atoms in the diacid), which is the world's first synthetic fiber. Later, when it was commercially produced, it had today's name - nylon. Until today, nylon is still the fabric raw material that is often used in our daily life, and the industrial application of nylon is constantly being developed and expanded. Finding alternatives to Japanese silk raw materials Before nylon was invented, people's clothes and socks were mainly made of cotton or silk. The United States is the world's largest consumer of silk. The original raw materials came from China. After the Opium War, Japan gradually replaced China as the main country that imported silk raw materials to the United States. The raw materials imported by the United States from Japan accounted for 90%. However, the enmity between the United States and Japan soon affected the industrial chain, and Japan cut off the export of silk raw materials, causing the United States to suffer heavy losses. The raw materials are in the hands of other countries, which is a very serious threat to the United States. Researchers began to study and develop high-quality man-made fibers. Wallace Hume Carothers hired by DuPont originally taught at Harvard University. After entering DuPont, he pulled up a team and started experimenting. In the summer of 1931, Julian Hill in the team discovered an interesting phenomenon when he took out the molten polyester from the reactor: the polymer could pull out filaments like melted syrup, and the fibrous The filaments can continue to be stretched after cooling, and the stretching length can reach several times the original. After cold stretching, the strength and elasticity of the fiber are greatly increased. After another three years of repeated exploration, the Carothers team synthesized polyamide polymer compounds on February 28, 1935. In 1937, DuPont commissioned the United Socks Factory to develop nylon stockings. In the same year, the first pair of nylon stockings came out. On October 27, 1938, DuPont's nylon stockings were officially unveiled at the New York World's Fair, setting off a fashion frenzy. On May 15, 1940, 4 million pairs of brown nylon stockings were sold out in just a few days after their debut in the United States. This modern product, which is as thin as a cicada's wing and is stronger and more durable than previous stockings, attracted the ladies of the time. Star technology in World War II After the advent of nylon, it was produced into various products, but nylon stockings left a strong mark in history, which is impressive. The reason behind it is the shortage of materials brought about by World War II. A few years after nylon stockings became popular in the West, the world fell into the swamp of World War II. Nylon raw materials in American factories are preferentially used to produce military products, such as parachutes, body armor, shoelaces, mosquito nets, hammocks, etc. The American army armed with nylon became an army representing the power of modern technology. Later, some commentators even believed that nylon was "the fiber that won the war." Up to now, nylon products are still an important part of military products. Among the "military fans", there is a group of people called "Nylon Party", which means people who like to collect individual soldier's equipment, and these equipment are mainly nylon products. The first large-scale use of nylon in military equipment was during World War II, when the U.S. military equipped the airborne troops with nylon parachutes produced by DuPont. In 1965, the U.S. military began to send troops into Vietnam, where they came to the hot and humid tropics. The canvas materials used by the U.S. military in the past were equipped in a high-humidity environment, and their anti-corrosion and wear resistance were not as good as nylon products. In order to meet the needs of the Vietnam battlefield, the US military began to use nylon products in large quantities. In the 1970s, the Soviet Army also began to use nylon materials on individual soldier equipment. Since then, canvas products have basically been eliminated in the army. During World War II, factories were unable to take care of civilian goods such as silk stockings, so nylon stockings became scarce and in short supply. To pretend they were wearing nylon stockings, women even started painting their legs with black threads that mimic stitches. Demand led to a service dedicated to women's legs, which at the time was like nail salons that can be seen everywhere on the street today. Nylon opens up modern life World War II is finally over, and people who rebuild their homes have a stronger desire for a better life, and nylon stockings have become the object of everyone's pursuit again. When the war ended and nylon stockings resumed production and returned to the market, there were long queues at the door of the stores, and there were even scenes of chaotic looting in some stores. Later, as DuPont simplified the production process, the supply of nylon stockings gradually met the market demand. The field of using nylon is far from just clothing and military. The most common sutures in the medical field are sutures made of nylon. Because nylon is both flexible and corrosion-resistant, some parts of the car are also processed with nylon. Modern automobiles are constantly pursuing lightweight and cost reduction. At the same time, the parts on the automobile need high and low temperature resistance, oil resistance, chemical resistance and certain mechanical properties, and nylon can meet these requirements. Where the car can be seen - seat belts, etc., are made of nylon. The invisible parts of the car - airbags, brake pads, fan blades, various gears, radiator water chambers, air filter housings, etc., are also nylon products. The emergence of nylon has greatly reduced the cost of people's daily necessities and industrial products, and has also brought more possibilities for product innovation. The continuous stream of nylon products on the production line brings people into the real modern life.
