Affected by the domestic cotton policy, China's regenerated cellulose fiber (viscose) industry expanded aggressively during the 12th Five-Year Plan period. The production capacity of some leading enterprises is still more than 200,000 tons in 2011, which has doubled by 2015 to more than 400,000 tons. "The three-year cotton purchasing and storage policy made the price difference between domestic and international cotton large, and the textile enterprises increased the amount of regenerated cellulose fiber.The demand growth stimulated the regenerated cellulose fiber industry in our country to be in a state of" false prosperity " Capacity of the stage, the structural characteristics of excess highlights. "An industry source said so. During the "13th Five-Year Plan" period, the regenerated cellulose fiber industry is facing pressure to reduce production capacity and the transformation and upgrading will accelerate. In this process, due to the shrinking profit space, coupled with more and more severe environmental pressures, conventional regenerated cellulose fiber products in order to have greater breakthrough development has been more difficult, functional, differentiated regenerated cellulose fiber is Important breakout direction. In the functional regenerated cellulose fiber, flame-retardant regenerated cellulose fiber will play an important role. An industry insider pointed out: "During the 13th Five-Year Plan period, high humidity modulus, flame retardant and tencel will be the three important directions for the upgrading of regenerated cellulose fiber products, of which the flame retardant regenerated cellulose fiber is expected to grow to So, what kinds of flame-retardant regenerated cellulose fibers are currently on the international market? What are the market applications? What are the advantages and disadvantages of products? The development of China's flame-retardant regenerated cellulose fibers How? Currently there is a breakthrough innovation? Flame Retardant regenerated cellulose fiber future prospects in China how? Products used in a wide range of what kind of impetus? In this issue, "China Textile News" reporter interviewed regenerated cellulose fibers Many people in the industry, to solve this. "Phosphorus" and "silicon" dominate the global market The enterprises producing flame retardant regenerated cellulose fibers in the international market are mainly divided into two "genres." The largest "genre" is none other than Austria Lenzing company. Its products are "phosphorus-based" flame-retardant regenerated cellulose fiber, which has been widely used in military service uniforms, firefighting firefighters and other fields in various countries for decades. It has established an unshakeable market in the international market of regenerable regenerated cellulose fibers "Overlord" status, firmly occupy the high-end market. However, Lenzing's "Phosphorus" products are not perfect, and the clothes they are woven in can not be worn in the body. Therefore, they have not been applied in the field of textile products. What's more, its most "fatal" flaw is the massive release of harmful gases in the event of a fire and the smothering of people with large quantities of smoke. In view of this, some areas in the United States are gradually beginning to limit the use of "phosphorus-based" flame retardant regenerated cellulose fibers. Another big "genre" is a "silicon-based" flame-retarded regenerated cellulose fiber product produced by Japanese companies. Japan's "silicon" products flame retardant effect is very good, but also more environmentally friendly, will not release toxic fumes after the fire burning, flame retardant, excellent environmental performance, but also has defects, can not be washed, once the washing, the flame retardant effect Will be lost. At the same time, the fiber strength is low, can not be spun and woven. These shortcomings led to Japan's "silicon" products can not usually produce high-end textile products, can only be used as fillers and non-woven fabrics, mainly occupy the low-end market, and the lower yield. However, there are also a small amount of fiber woven into low-end flame retardant fabrics. Sales of foreign products in the Chinese market, sales of flame-retardant regenerated cellulose fiber is currently Lenzing "a dominance." Moreover, because Lenzing in the upstream and downstream industry chain has a strong advantage, its flame retardant regenerated cellulose fiber in the downstream market is very competitive. In addition, Japanese companies also have some sales in 2015. "Lan Jing in China's market and the downstream application of enterprises formed an alliance, the purchase price within the Union concessions, about 80,000 yuan / ton; if it is outside the Union procurement, the price is about 100,000 yuan / ton. Style of work to domestic enterprises formed a lot of competitive pressure. "A domestic leader in regenerative cellulose fibers such a feeling of emotion. From a production point of view, some regenerated cellulose fiber enterprises in our country are gradually involved in the production of "silicon-based" flame retardant regenerated cellulose fiber products, including Sanyou Tangshan, * ST Hailong and Jiangsu Aoyang Technology. However, the average annual output is not large, about 5,000 tons to 10,000 tons, the main export-oriented products, used to make flame retardant products and non-woven fabrics. In general, the added value of flame-retardant regenerated cellulose fibers currently produced by our enterprises is relatively low, and the price is only 1,000 yuan / ton to 2,000 yuan / ton higher than ordinary regenerated cellulose fiber products, about 14,000 yuan / tonne, and Japanese companies have a big price gap. The birth of a new generation of "silicon - nitrogen" environmentally friendly spinnable products International measurement of flame-retardant regenerated cellulose fiber is environmentally friendly, mainly in the following indicators: First, the fiber combustion will not release harmful gases, the second is the combustion will not produce A lot of smoke, the third is decomposed after the soil, water and other will have a hazard. Why "phosphorus-based" products in the case of larger defects, can still stand the world flame retardant regenerated cellulose fiber market? "This is because the flame retardant effect is indeed very good, limit oxygen index (a measure of flame retardancy Index) is greater than 28. Moreover, the basic business of Japanese products can not be woven into textile products, combined with the international market for a long time did not appear a better product, so "phosphorus system" of course is the first choice. "A production of flame-retardant regenerated fiber The person in charge of textile fiber said. Perhaps it is precisely because the "phosphorus" and "silicon" two categories of flame-retardant regenerated cellulose fiber products are not so perfect, but for our business to develop a new generation of flame-retardant regenerated cellulose fiber provides room. During the interview, Sailan Flame Retardant Fiber Co., Ltd. in Beijing currently developed "a whole new generation of environmentally friendly silicon-nitrogen flame-retardant regenerated cellulose fibers." The fiber is environmentally friendly, safe and comfortable, but also permanent flame retardant, and has good spinnability. Beijing 赛 Oulai Flame Retardant Fiber Co., Ltd., chairman of Bishui Ping introduced the company's products limit oxygen index (a measure of the flame retardant performance) ≥ 30%, the average smoke density Ds4.0 Although not yet mass-produced, but due to product integration Excellent performance, the end of 2015, Sailoulan has reaped several orders. A company specializing in the production of fire protection clothing and personal protective clothing in Germany undertakes orders in Europe and special textile processing plants in China to purchase cotton yarn from domestic textile enterprises. At the end of last year, the company started buying Cyrel's products through the textile company. Another client is a textile company in the United States, whose main business is the processing and production of specialty-style garments that they have already started trials of. Bi also introduced, in addition to protection, fire service, the use of Sailoulan products in the mid-market can be used to weave aircraft, ships, high-speed rail and other areas of soft decoration, has now begun cooperation with some spinning enterprises large sample Spinning. In addition, after mass production, will also be used for textile products. In this regard, an industry expert pointed out: "The domestic flame-retardant textile market is currently mainly occupied by two types of fibers, one is flame-retardant polyester, flame-retardant acrylic and other synthetic fibers, the other is the phosphorus-based products.If the new Spinning, comfortable and better flame retardant regenerated cellulose fiber products can be mass-produced in the home textile market will have a very good prospect. "At the same time, from the product value-added perspective," a new generation of environmentally friendly silicon - nitrogen resistance Burning regenerated cellulose fiber "higher value-added, the price is about 5 to 6 times the ordinary regenerated cellulose fiber products. Prospects still need the law "escort" Jiang Jun Zhou, vice chairman of China Chemical Fiber Industry Association pointed out that the future prospects of flame retardant fiber is very promising, its military apparel, firefighters field applications needless to say, the greatest development prospects should be In the field of civilian textiles applications, including home curtains, hotel bedding, sofa cushions, school uniforms and so on. In fact, the standard "Burning Performance Requirements and Labeling of Flame Retardant Products and Components in Public Places" formulated by the Ministry of Public Security of our country started as early as 2007. The standard specifies the definition and classification of flame-retardant products and components used in public places, combustion performance requirements and labeling and other content, provides for the use of public places, construction products, flooring materials, wires and cables, sockets, switches, lamps, home appliances shell Plastic products, as well as the seat, sofas, mattresses used in the insulation layer and foam combustion performance, put forward the corresponding level of flame retardant standards. However, from the actual situation, the effect of implementation over the years is not satisfactory. "In developed countries such as Europe and the United States, beds and sofas in hotels and the like must be made of flame-retardant fibers and students must also use flame-retardant materials in school uniforms, which is a compulsory requirement based on national laws and regulations. Therefore, Flame-retardant fiber to promote a wide range of countries still need to accelerate the relevant laws of the country.Please think that if the relevant laws and regulations of the domestic five-star hotel mattresses, sofa cushions, etc. must use flame-retardant fiber, then the demand will be driven quite Big.If the student uniforms also legally required the use of flame-retardant fibers, the demand will be greater, "Jiang Jun Zhou predicted. At the same time, with the gradual improvement of domestic consumer awareness, flame retardant fiber in the field of home textiles will gradually expand the use. Jiang Jun Zhou stressed: "Now more and more high-rise buildings in the city, in case of an accidental fire, how to escape high-level residents is a big problem.In fact, in many cases the victims of the fire is not directly caused by fire, but was choked by smoke In the past, can not escape .From the security point of view, high-rise household goods should be essential flame retardant materials, such as the use of fire-retardant sofa cushions, fire-retardant ropes, etc. Therefore, the future of flame-retardant fiber in the civilian field of broad application Need to be vigorously publicized to consumers. "In addition, how to make flame retardant fiber industry chain planning, in its future development is also crucial. Zhao Xiangdong, vice president of China Chemical Fiber Industry Association, pointed out: "The research, development and launch of environmentally-friendly, flame-retardant regenerated cellulose fibers are in line with China's industrial policies and future development directions." He said that the key issues to be solved by the chemical fiber industry in the "13th Five-Year Plan" One is to solve the production and demand balance. Capacity of the domestic regenerated cellulose fiber industry is currently at a certain stage of excess. In 2015, the market of regenerated cellulose fiber thrived in the sub-categories of chemical fiber. The reason was that some enterprises were shut down for environmental protection and rectification. After the market supply decreased, the price rose. Chemical fiber industry to implement "supply-side reform", the most basic one is that companies must develop a real good product. Therefore, the introduction of innovative and high value-added products such as the new environmentally-friendly flame-retardant regenerated cellulose fiber has enriched the overall product structure of the regenerated cellulose fiber industry and can better meet the needs of downstream enterprises. The prospect can be expected.
