In the past ten years, the textile industry has taken fabrics as a breakthrough, applied high-tech and advanced applicable technologies to transform traditional industries, and achieved good results, which has effectively promoted the technological progress and industrial level of the textile industry. However, with the accelerating process of economic globalization, the competition in the textile industry is also intensifying. China's textile industry must maintain its advantages in a more competitive environment, and it should not only stay in the labor cost advantage and textile quantity advantage. The key is to further Improve the level of textile technology, rely on technological innovation to increase the technical content and added value of products, and enhance the competitiveness of China's textile industry in an all-round way.
To this end, we have organized professional associations and relevant experts to analyze the status quo and existing problems of the industry, and put forward 25 key technologies in the four aspects of the textile industry that are urgently to be solved. The solution of these key technologies will greatly promote Technological advancement and development of the industry.
Textile new materials and advanced processing technology new materials are one of the most important high-tech materials today. The application of new textile materials not only makes great changes in people's lives, but also promotes the rapid development of social economy. The development of international textile new materials mainly focuses on the research and development of high-performance fibers with excellent properties, functional fibers, new fibers that meet sustainable development and new materials.
High-performance fiber has high strength, high modulus, high temperature resistance, strong corrosion resistance and fire resistance. It is widely used in transportation, water conservancy, military, health, construction, communication, environmental protection and other fields.
Functional fiber has antistatic, flame retardant, high moisture absorption, antibacterial, deodorant, anti-ultraviolet and other characteristics, is the basis for the production of high value-added, high-grade textiles.
The production of conventional chemical fiber products is based on high-capacity, high-efficiency, high-speed, continuous and network information monitoring, achieving efficient and low-cost production.
Industrial fiber will become an important raw material for the manufacturing industry in the future. Industrial fibers have been widely used as substitutes for metals, plastics, paper and asbestos. With the development of lightweight, high-performance, diversified and aesthetically pleasing industrial materials, industrial fibers are increasingly used, and market demand is expanding. For example, industrial fibers in the United States, Japan, and the European Union are The entire fiber production sector has accounted for 2/3 of the total. In the next 10 years, China's industrial fiber consumption and market trade will grow by more than 10% annually.
Specifically, we must develop the following 10 key technologies:
1. Carbon fiber, aramid, polysulfonamide, a new generation of ultra-high strength and high modulus polyethylene and vinylon fiber industrialization research and development of carbon fiber, aramid and other fiber developed countries have already achieved industrialization, but China is still in a small, pilot stage, urgently Industrial development and application. For the domestic sulfonamide which has a certain development foundation, it should be invested in development to form an industrialized production line with an annual output of 500 tons. Fibers such as polybenzobisoxazole (PBO), which have excellent performance and wide application, should be pre-study and made into technical reserves. At the same time, it is necessary to deepen research on the application technologies of the new generation of ultra-high-strength high-membrane polyethylene and K-series vinylon, which have already been based in China, to improve product levels and achieve industrial upgrading.
2. The new polyester diversified technology varieties PTT, PEN, CO-PET and other industrialized R&D have entered the new century. The world's new polyester technology has developed very rapidly. The industrialization of multi-new and new varieties of polyester family represented by PTT Significant progress has also been made in development. PTT (polytrimethylene terephthalate) dyes well, elastic, crisp, dry, easy to process, strong stain resistance, and has the characteristics of polyester, nylon and some spandex fibers, not only for fabrics, carpets, nonwovens It can also be used in new resin materials such as film and plastic, and has broad development prospects; PEN (polyethylene glycol diethylene glycol) has good transparency and barrier properties, which is conducive to the expansion of polyester in high-performance non-fibrous fields such as beer bottles; CO-PET is mainly used for the production of sea-island fiber, and it is a key species that needs to be prioritized in the development of modified PET.
3. Degradable PLA (polylactic acid fiber) and Lyocell (new solvent method cellulose fiber) fiber and product industrialization development LA is a kind of fully biodegradable polymer, which is based on natural biological resources such as corn starch. The new fiber material with successful raw material development has the advantages of luster, comfort, durability, smoothness and quick drying. In particular, its superior biodegradability and applicability have attracted worldwide attention, including the United States, Europe, Japan and Taiwan. Intensive research on industrialization. Loycell is a new generation of cellulose fiber produced by a new solvent and non-toxic process. It has the performance of man-made fiber and synthetic fiber. There have been many achievements in product application and development in China, but it is urgently needed to develop in fiber industrialization.
4. Soy protein series fiber and product development technology Soy protein fiber is a plant protein modified fiber that has been independently researched and developed in China and successfully obtained industrial test for the first time in the world. The fiber not only has moderate strength, small specific gravity, soft hand feeling, soft gloss, excellent moisture absorption and moisture permeability, good skin-friendly property, obvious antibacterial function, and meets the requirements of comfort and health. At present, China has built a 10,000-ton soybean protein fiber processing production line, and further develops soybean protein fiber products to improve the automation control level of the equipment. At the same time, it is necessary to systematically study the key technologies of soybean protein fiber spinning, weaving, printing and dyeing. The development of pure textile, blended, interwoven and other fabrics, so that the industrialization of soybean protein fiber products into a new stage.
