China's Cotton Textile Industry Takes The Road Of Characteristic Becoming Inevitable.

Chinese cotton recently held Spin On the forum of industrial collaborative innovation development, the association leaders and academician Yao Mu of the Chinese Academy of engineering, Dr. Shi Mei Wu of the general military equipment Research Institute of the PLA, and Xu Weilin, Professor of Wuhan Textile University, and nearly 400 representatives of cotton spinning and weaving downstream related enterprises have discussed the theme of "technological innovation and coordinated development". Cotton textile industry Innovation and development.

We have gathered the essence of the forum's experts' speeches, hoping that readers can get inspiration from them.

　 1, enterprises should be refined, specialized and special.

Yao Mu, academician of the Chinese Academy of Engineering

China's textile industry is facing more unfavorable factors because of the "re industrialization" of the economically developed textile giants and the transfer of low and intermediate textile products to South and Southeast Asian countries. Cotton textile enterprises are the main body of technological innovation. Enterprises should concentrate on doing fine, doing specialization and doing special things, so as to ease the problem of using cotton and speed up product innovation, so as to enhance the competitiveness of China's textile industry.

At present, our country textile industry A new competitor has been added, that is, the developed textile giant. Over the past 3 years, developed countries led by the United States and the United Kingdom have proposed to re industrialize after the process of de industrialization. A number of new cotton mills have already started in the US. This shows that the competition pattern in the international market is changing, and it is not just our original competitors who are competing with us. China's manufacturing industry, especially China's textile industry, must be sober minded, global oriented, down-to-earth and solid innovation, and strive to implement the guiding principle of combining "politics, production, learning, research and application", striving to win ahead, and overcome the double pressure of "advanced industrialization" of the developed textile giants, and the shift of low and medium grade textile products to South Asian and Southeast Asian countries.

As the global population has exploded, especially since China has changed from a net exporter of grain to a net importer of grain from 2009, natural fibers must be changed to the "grain fields" instead of "arable land", and should be transformed into saline alkali land, wasteland, cultivation and Cultivation on the hillside, so as to make full use of agricultural waste products and new varieties as raw material sources. In recent years, natural textile fibers have begun to develop and apply many new varieties, such as kapok, island cotton upland woody species, horn horn melon fiber, nontoxic or low toxic hemp, bamboo fiber, lotus stalk fiber, sugar cane fiber, raccoon wool, fox hair and so on. Regenerated cellulose fibers should be made full use of waste crop straw and new regenerated cellulose fibers, such as alginate fiber, chitin fiber, chitosan fiber, polylactic acid fiber, etc.

There are two main types of synthetic fiber, which are worthy of attention. One aspect is high performance fibers, which mainly include high strength, high modulus, super high strength, super high modulus, high temperature resistance and ablation resistance. Because high-performance fibers and textile materials become an important basic material that can replace hundreds of metal materials. The other is new functional fiber. Now the functional fibers are in clothing Household and other aspects play a greater role, such as waterproofing, oil proofing, antifouling, moisture permeability, sweat transmission, quick drying and high water absorption. In addition, we should also consider the functions of adding bacteriostatic, deodorant, mosquito repellent, and even anti mite.

Cotton textile enterprises are the main body of technological innovation in the industry. In terms of product development, cotton textile enterprises should understand the advantages and disadvantages of cotton fibers and make full use of other fibers to give full play to their characteristics, especially to bring into play the characteristics of new fibers such as high performance and new functions. We should attach importance to the combination of short fiber spinning and filament, develop new varieties, develop new functions and strive for new markets. We should attach importance to product quality, improve user satisfaction and make excellent products in combination with culture, fashion, green, environmental protection, health and brand factors. We should attach importance to the development of the final products and the development and control of the terminal market. The upstream and downstream enterprises can jointly build industrial technology innovation strategic alliances and build a complete industrial chain.

2 develop special protection Textile market

Shi Meiwu, senior engineer of PLA General Equipment Research Institute

At present, the market for special protection textile With the increasing demand for labor protection equipment, China should change the old, individual, manual workshop obsolete mode of production as soon as possible, strengthen the development of high performance price specific protective textiles, expand the use of the surface with low cost, and enhance the protection effect.

The number of abnormal deaths caused by production safety problems in China is more than 200 thousand each year, and more than 3 million people are injured. 15% of accidents in various types of production casualty accidents are related to personal protective equipment: or are not equipped, or not used, or improper use or poor performance. China's protective clothing needs more than 80 million sets per year and protection. shoes It needs about 100 million pairs and more than 156 million kinds of dust respirators. The cost of labor protection articles for employees is 300 yuan per person to 1500 yuan per person per year. The potential market capacity of protective equipment reaches 100 billion yuan.

More than 80% of the national labor protection equipment manufacturing enterprises are small enterprises, and 70% of the enterprises stay in scattered, individual, manual workshops. Several leading enterprises in the global labor protection equipment market occupy most of the market share in this field. But because of the high price, it is not widely used in China. Therefore, the textile industry should do something in special protective textiles and labor protection equipment.

With the progress of science and technology, the number of hurting factors has increased. First of all, the natural space of human beings is more extensive, and the artificial physical and chemical and biological environment is more diverse. Secondly, the harmfulness of various environmental factors is also increasingly mastered. In addition, people pay more and more attention to their safety and reduce the safety threshold.

Equipment, such as helmets, helmets, cold helmets, insect resistant caps, etc.; respiratory protective equipment, such as dust respirators (face mask), gas mask, etc.; eye and face protection equipment, such as welding eyepiece, furnace goggles, anti impact goggles, etc.; hearing protection equipment, such as earplugs, earmuff, anti noise cap, etc.; hand protection equipment, such as general protective gloves, various special protection (waterproof, cold, high temperature, anti vibration, anti cutting) gloves, insulating gloves; foot protective equipment, such as dust-proof, waterproof, oil resistant, anti smashing, anti-skid, high temperature, anti-static, acid, shockproof shoes (boots) and electricity. According to the classification of human body protection, there are 10 kinds of textiles for special protection: head protection. Insulating shoes (boots) and so on; trunk protective equipment, such as general protective clothing, waterproof clothing, cold proof clothing, oil proof clothing, electromagnetic shielding clothing, thermal insulation clothing, acid proof alkali clothing, antistatic clothing, anti nuclear clothing, and other special protective clothing; skin care products; fall protection equipment and other protective equipment varieties, such as water life buoy, life jacket, etc.

At present, special protective textiles have been taken seriously. Some of the damage factors have been implemented by mature technology, but there are still some hurting factors which can not be protected or prevented simultaneously. Some protection technologies are in the stage of rapid development and active promotion. Relatively mature protection technologies include antistatic technology, electromagnetic shielding technology, high-strength wear-resistant technology, bulletproof technology, stab prevention technology, anti-bacterial technology, insect repellent technology, flame retardant technology, arc protection technology, welding protection technology, molten metal protection technology, drowning rescue technology, air purification and filtration technology.

The main problems currently facing special protective textiles include material problems, processing technology problems, testing conditions, design of protection systems, and contradiction between performance and price. The development trend of special protective textiles is to further improve the protection system, carry out systematic design of protective equipment and performance design of special protective textiles, and establish a sound standard system, including basic standards, product standards, testing methods and standards, and establish application guidelines. Special protective textiles will be more specialized, intelligent, systematized, functional modularized, and improve comfort and efficiency. We should strengthen the development of high performance price specific protective textiles, expand the use of the surface with low cost, and enhance the protection effect.

　 3 fiber innovation to enhance the value of industrial chain

Chinese Chemistry textile industry Li Zengjun, Deputy Secretary General of the Association

With the improvement of people's living standard, pure cotton products can no longer satisfy people's pursuit of diversification of textile products. At the same time, the "cotton problem" also forced some cotton spinning enterprises to find cotton substitute. Under the current market situation, China's textile enterprises should increase the innovation and application of chemical fiber, promote each other's technological innovation and brand creation, and enhance the value of the whole industrial chain.

Chemical fiber plays an important role in China's textile industry system. The use of chemical fiber accounts for about 73% of China's textile fiber processing. Especially in the case of the cotton system and the huge difference between domestic and foreign cotton, which has become the core issue of textile industry's concern, chemical fiber has largely filled the shortage of domestic cotton supply and effectively safeguards the operation and market stability of the textile industry. In 2012, Cotton spinning industry The amount of chemical fiber used to reach 11 million 700 thousand tons, while the amount of cotton used is about 9 million tons.

In the past two years, the operation of the chemical fiber industry has been generally good. Especially in 2010 and 2011, viscose and polyester staple fibers have seen high profits for 20 years. The benefits have shown a good historical situation, making the industry's attention both inside and outside the company continue to rise, investment enthusiasm is high, and the planning projects and production capacity of each enterprise are larger. In 2012, the production capacity of polyester staple fiber was more than 90 tons. It was the sum of the previous years, and more than 40 tons of viscose staple fiber were put into production. The concentration of new capacity will inevitably increase the supply pressure of the market. Due to the sluggish demand, the market competition will further intensify, the device load will be low, and the production cost will also increase significantly. In 2013, more than 40 tons of polyester staple fiber plan was put into operation, the capacity growth rate was around 7%, the viscose staple fiber production capacity increased by more than 40 tons, the capacity growth rate was around 13%, the productivity growth rate returned to a reasonable level, and it could fully meet the growth of downstream demand.

Today's cotton market, pure cotton products are no longer the mainstream, and all kinds of chemical fibers occupy half of the cotton spinning industry. At the same time, with the improvement of people's living standard, pure cotton products can no longer satisfy people's pursuit of diversification of textile products. On the one hand, the market trend has asked cotton spinning enterprises to take the initiative to seek opportunities for chemical fiber products. On the other hand, the "cotton problem" has forced some cotton spinning enterprises to try to use chemical fibers.

At present, the main chemical fiber staple used in cotton spinning industry is polyester staple fiber, viscose staple fiber and regenerated polyester staple fiber.

Viscose fiber is the main variety of regenerated cellulose fiber. In 2012, China's capacity reached 3 million 290 thousand tons, and its output reached 2 million 733 thousand tons. In the past 5 years, the compound growth rate reached 19.98%, and the technology level and engineering level were at the advanced level in the world. As viscose fiber production process is long, "three wastes" pollution, old equipment and higher production costs, western developed countries and South Korea and Japan have gradually stopped the production of viscose fiber, and China has also formulated the admittance conditions of viscose industry. At present, the growth of viscose fiber production capacity in the world is mainly concentrated in China.

On the level of equipment, the flexible production equipment of viscose staple fiber is becoming more and more mature, which has greatly promoted the technological progress of the industry. The localization technology has formed an annual production line of 30 thousand tons, 50 thousand tons, and 60 thousand tons of viscose staple fiber. In terms of reducing energy consumption, material consumption, emission reduction, "three wastes" treatment, product quality improvement, investment cost reduction, and operation cost reduction, etc., they have been improved to varying degrees. The overall technical level of the industry has reached the advanced level of the world. The technology of short fiber single line production equipment is ahead of the world's advanced level.

The regenerated fiber produced from bamboo pulp and hemp pulp is a kind of regenerated cellulose fiber developed in China in recent years. At present, Jilin chemical fiber Limited by Share Ltd, Hebei jishajiao Chemical Fiber Co., Ltd., Shandong Hailong Limited by Share Ltd, the PLA General Logistics Department Quartermaster Equipment Research Institute and many other enterprises are studying and developing these products. The viscose long and short fibers made from bamboo pulp and hemp pulp have entered industrial production. At present, bamboo fiber production capacity is about 55 thousand tons. In 12th Five-Year, 215 thousand tons of production capacity will be formed. Manufacturing enterprises have the proprietary technology of independent development, including products of Tianzhu, Yuzhu, Yun Zhu and Sheng Ma, which are welcomed by consumers.

Many viscose products in China are leading in product quality, variety and technology level. At present, a variety of differentiated products have been developed, such as modal, Newdel, lissai, nonferrous metals, high whiteness, flame retardancy, bamboo pulp, hemp pulp, bamboo charcoal, chitin, anion, medical stone, pearl, air conditioning fiber and other products, and have been applied in industry. The double pressure of environment and cost has seriously hindered the development of viscose fiber. However, the Environmental Friendly Non viscose cellulose fibers such as Lyocell and Novel have attracted the attention of experts at home and abroad.

along with Spinning technology With the progress of the level, the fine denier staple fiber used in the high count yarn market is better. At the same time, cotton imitation, comfort, moisture absorption, sweat absorption, warmth retention, coloring, cationic dyeability, flame retardance, antibacterial, ultraviolet and far infrared difference, and functional polyester staple fiber also show a variety of morphological, functional and functional composite modification trends, and have been widely applied in textiles.

Fiber is Textile industry The starting point of chain is only the promotion of technological innovation and brand creation of fiber and terminal products, and the superposition effect. Only in this way can we speed up the overall level of China's textile industry and enhance the value of the whole industrial chain.
