Chemical fiber: Seeking differentiation to make textile industry “Yuan Longping”

Differentiated development is the embodiment of high value-added industries. It is the core strength of the high-end competitiveness of the industry market, and is also the direction that most enterprises should choose. The China Chemical Fiber Association proposed that: During the “12th Five-Year Plan” period, the main directions for the differential development of China's chemical fiber industry are high-performance differentiation, ultra-fine denier, functionalization and compounding.

In 2010, cotton prices fluctuate drastically and run at an overall high level, causing unprecedented difficulties in the production and operation of enterprises. In the face of high raw material costs and limited supply, the textile industry urgently needs “Yuan Longping” in the field of textile materials to solve issues related to industrial safety. At present, the use of chemical fiber to replace cotton fiber is also growing louder, which will certainly promote China's chemical fiber industry to accelerate the progress from quantitative growth to species differentiation, will certainly accelerate the rapid development of chemical fiber industry super simulation technology.

Although development is fast, "hard injuries" still exist

In recent years, China's chemical fiber industry has experienced a period of rapid development. However, it is mainly based on the expansion of conventional fiber production capacity. The problem of over-development of conventional and homogenized products is prominent, and there are serious shortcomings in product development and technological innovation. For various reasons, compared with many developed countries, the current differential rate of chemical fiber products in China is still relatively low, manifested in a small variety of products, small production and quality levels are not high.

The chemical fiber enterprises in developed countries pay attention to the development of chemical fiber products. Each year, the number of production varieties can reach more than 100 kinds, and the production of each type does not exceed 5% of the total output. High-performance differentiated fibers developed by Japan, South Korea, and other countries have reached the fourth-generation level of super-fibres, while most of the differential fibers in China still remain at the second-generation level. In the development of differentiated fibers and developed countries There is a big gap.

To this end, Ye Yongmao, chief technical advisor of the China Chemical Fiber Industry Association, pointed out that the development of differentiated products is a systematic project and cannot be limited to product development. It must also focus on marketization and engineering. It requires close integration of production, study, and research. In addition, the supporting development of related materials is also very important. It must also combine its own technology and equipment characteristics, find out market requirements, develop products with its own characteristics, form differentiated competition, and avoid rushing to the top.

Ye Yongmao pointed out that apart from factors such as technology and funds, the most important factor in the current impact on the differential development of enterprises is the market. To solve the problem of poor integration of differentiated fiber and downstream product development, it is necessary to establish a cooperation platform between upstream and downstream to enhance communication and cooperation from information to production. In addition, the lack of promotion of differentiated products and the lack of market awareness of the brand are the current prominent status of the domestic chemical fiber industry, which has led to the current industry chain profits generally tilted toward the weaving, especially the apparel industry. For example, he says, a T-shirt that absorbs moisture and wicks fiber is more than twice as expensive as regular fiber, and moisture-wicking fibers are only two or three percent more expensive per ton than conventional products of the same specifications.

Zheng Zhiyi, honorary president of China Chemical Fibre Industry Association, said that "differentiation" was first proposed by Japan in the 1980s and played an important guiding role in the development of the world's chemical fiber industry. At present, through the joint production, research, and other methods, the development level of China's differentiated fibers has been continuously improved, with more than 20 differentiated varieties. The total amount of differentiated fibers totals 12.79 million tons, of which 1.15 million tons belong to a variety of differentiated composite products. As of the end of 2010, the differential rate of chemical fiber in China has increased to 47%.

"Sihua" clearly defines the direction of development

The "12th Five-Year Plan" in the post-crisis era is an important transition period for the development of China's chemical fiber industry, and it is also a critical period for the first half of the 21st century. The "12th Five-Year Development Plan for China Chemical Fiber Industry" drafted by the China Chemical Fiber Association (Draft for Soliciting Opinions) proposes a more comprehensive and operational constraint and guidance on market, structure, circulation, and sustainable development. The goals and tasks set the main tasks for the differential development of China's chemical fiber industry are the following four aspects: high-performance differentiation, ultra-fine denier, functionalization, and compounding.

The first is the differentiation of high-performance, development of "five imitation" fibers (super imitation cotton, super imitation wool, silk, super imitation hemp, simulation leather), to achieve ultra-high performance, super-simulation goals. Based on the research and development of differentiated fiber varieties, we will focus on the development of new differentiated fibers. The main varieties include the new generation of cationic high-shrinkage, multi-type heterogeneous, two-component low-melting fiber, composite microfiber, microdenier fiber, a new generation of island staple fiber and products, high water absorption, high moisture absorption and moisture permeable fiber, anti-pilling and pilling , Multi-functional mixed fiber, high-strength and high-humidity modulus viscose fiber, two-component three-dimensional crimp, self-elongating fiber, four different fibers (heterogeneity, different cross-section, different materials, different shrinkage), a new generation of colored fibers, fluorescence increase White fiber, cement-reinforced high-performance weather-resistant polypropylene fiber, weather-resistant polyester fiber for civil engineering, imitation down and super feather fiber, imitation cashmere wool and ultra-cashmere wool fiber, fine denier polypropylene dyeable fiber, fine denier nylon fiber, etc. .

The second is ultra-light denier. The fine denier and ultra-fine denier of fibers are still an effective way to tackle high-grade fiber materials with synthetic fibers and cellulose fibers. To achieve high-order structure of fiber materials, precision, homogeneity, to solve the problems of fine-denier fiber structure and surface properties. Fine denier chemical fiber monofilament fineness, small flexural modulus, flexible fiber, its fabric is fine and delicate, soft and smooth, smooth and excellent drape, good covering, good taking, good detergency, optical Good performance, moisture wicking performance and rain waterproof performance.

The third is functionalization. Functional fibers mainly include: high-retardant, anti-droplet, high-conductivity, anti-static, conductive, anti-bacterial, odor-proof, radiation-proof, and other functional composite fibers, with the new touch-sensitive multi-functional polyester, nylon , Acrylic, all kinds of medical fibers, reinforced fibers for construction, high-strength high-modulus and low-shrinkage fibers, and antibacterial fibers with recyclable functions, polyamides, polyesters, polyolefin fibers, etc.

The fourth is compounding. The key research direction is to realize compounding, study and solve the problems of fiber structure and fiber surface modification. Through the interweaving and blending of different fibers, various fiber properties can be complemented.

Make every effort to improve the level of differentiation

Zheng Zhiyi stated that by 2015, the differential rate of China's chemical fiber industry will reach more than 60%, and the total amount of differentiated fibers will exceed 23.4 million tons. The differential production of polyester filaments will reach 140,000 tons, with a differentiation rate of 67%; the differential production of polyester staple fibers will reach 6 million tons, with a differentiation rate of 60%; the differential production of viscose filaments will reach 20,000 Ton, the differentiation rate is 8%; the differential production of viscose staple fiber will reach 750,000 tons, the differential rate is 25%; the differential production of polyamide fiber will reach 1.8 million tons, the differential rate is 60%; differentiation The output reached 150,000 tons and the differentiation rate was 25%. The entire industry achieves 50% of the total industry output value of differentiated products, and profits account for 60%.

Zheng Zhiyi further analyzed that since the Chinese consumer market has different levels of demand, it has produced a batch of “professional, small, refined, and unique” (professional-professional, small-flexible, fine-grade-quality products, special-characteristics The small and medium-sized enterprises featured by products and products are now represented by Xinxin Chemical Fiber, Jinhui Chemical Fiber, Fangyuan Chemical Fiber, Haitian Textile, Jiangyin Heshili, Xiake Environmental Protection, Guangdong Caiyan and Yibin Silkia. A number of advantageous enterprises focus on the production of high value-added and diversified products required by different levels of the market. Although the output of these enterprises is relatively small, they have a higher added value and bright colors. They are the main raw material production bases in the fields of textile, clothing and decoration. Zheng Zhiyi introduced that China's chemical fiber industry will strive to develop “professional, small, refined, and special” enterprises to more than 60 during the “12th Five-Year Plan” period, with output value accounting for more than 30% of the total output value of chemical fiber, and profits accounting for more than 40% of total industry profits.

Zheng Zhiyi pointed out that in the new era, the rapid development of science and technology is triggering profound changes in social production methods. The wide application of information network technology continues to drive changes in production methods. Flexible manufacturing, network manufacturing, green manufacturing, smart manufacturing, and global manufacturing are increasingly becoming the direction of change in production methods. The rapid development of the Internet, cloud computing, Internet of Things, knowledge services, and intelligent services provides powerful tools and environments for personalized manufacturing and service innovation. The combination of personalized manufacturing and large-scale collaborative innovation will become an important production method.

Personalized manufacturing can better reflect the artistry of culture, brand and color, and is an important symbol for the coordinated development of technology and quality. The rise and development of personalized manufacturing has provided the chemical fiber market with unlimited imagination and real market demands.

Differentiated development is the embodiment of high value-added industries. It is the core strength of the high-end competitiveness of the industry market, and is also the direction that most enterprises should choose.
