Textile industry "14th Five-Year" scientific and technological development guidance

The 14th Five-Year Plan period is the first five years of a new journey to comprehensively build a modern socialist country. The 14th Five-Year Plan for National Economic and Social Development of the People's Republic of China and the Outline of Long-term Goals to 2035 draw a grand blueprint for China's development in the 14th Five-Year Plan period and beyond. It upholds the central position of innovation in China's overall modernization drive and makes self-reliance in science and technology a strategic support for national development. We have made key arrangements for developing scientific and technological innovation and supporting high-quality development through science and technology. During the "14th Five-Year Plan" period, China's textile science and technology will adhere to innovation-driven development and comprehensively shape the new advantages of industry development on the basis of achieving a greater leap in innovation ability and output level. Centering on scientific and technological innovation to lead the high-quality development of the industry and achieve a high level of self-reliance in textile science and technology, this guiding opinion is compiled.

First, "13th Five-Year" textile industry scientific and technological progress

1. Achievements in scientific and technological development

 From 2016 to 2019, the scientific research and experimental development (R&D) expenditure of industrial enterprises above designated size in China's textile industry increased from 41.07 billion yuan to 49.52 billion yuan, and the R&D investment intensity increased from 0.57% to 1%; Industry scientific and technological achievements, a total of 11 achievements in the industry won the national science and technology awards, of which "dry spray wet spinning thousand ton high strength/hundred ton medium die carbon fiber industrialization key technology and application" won the first prize of National science and Technology progress, 398 achievements won the "textile light" China Textile Industry Federation science and Technology Award; The number of authorized invention patents in the industry maintained rapid growth, and nearly 40,000 effective invention patents were authorized, an increase of more than 60% over the authorized invention patents during the "Twelfth Five-Year Plan" period.

1. Remarkable progress in fiber material technology

Advanced basic fiber materials continue to improve in terms of efficient flexibility, differentiation and functionality. Polyester, nylon high-capacity, flexible and efficient preparation technology has generally reached the international advanced level, the functional modification of general fiber to double function, multifunctional composite modification development, expand the application field, improve the added value of products.

The key strategic fiber new material technology has steadily improved, and continues to meet the development needs of aerospace, national defense, environmental protection, medical and health fields. Carbon fiber dry spray wet spinning and wet spinning technology is gradually improved, production efficiency is further improved, high-end product varieties are gradually rich, T1000 grade, M40, M40J, M55J and other carbon fibers have engineering preparation capabilities, 25K large tow carbon fibers to achieve industrial production; The key technologies and equipment of thousand-ton para-aramid engineering have made breakthroughs, and high-strength and high-model para-aramid products have been localization; High strength and high modulus polyimide fiber, meta-aramid, polyphenylene sulfide fiber, continuous basalt fiber and so on have achieved rapid development. Bio-based fiber material technology has made new progress, and Lyocell fiber industrialization technology has realized localization; Bio-based polyamide (PA56) fiber broke through the technical bottleneck of bio-process glutenediamine and established a 10,000-ton production line; Polylactic acid fiber breaks through the lactic acid-lactide-polylactic acid technology, forming the whole industrial chain preparation technology; The industrialization technology of PTT fiber is mature, and the products form brand effect; The large-scale preparation technology of seaweed fiber has made a breakthrough, and the industrialization production of 5,000 tons has been realized. The raw material technology of pure chitosan fiber has been further optimized, and the products have been applied in many fields such as high-end dressings, war trauma first aid, repair membrane materials, drug carriers, tissues and organs.

2. The development of advanced textile products continues to strengthen

The development of functional textiles such as health protection, comfort and easy care has achieved remarkable results, and the functions of products are increasingly diversified, and the application fields are constantly expanding. Large-scale preparation of flame-retardant fibers and products such as long-acting flame-retardant, drop-resistant, smok-suppressive, etc., meets the requirements of flame-retardant protection in related fields; Wet and fast drying, cool feeling, heat and warm series of hot and wet comfort functional fibers and fabrics to achieve industrial preparation, further improve the wearing comfort of textile fabrics, to meet people's wearing needs in different environments; The high conformal technology of cotton, wool and other natural fiber fabrics has made breakthroughs, which has improved the wrinkle resistance and quality of textile products, and reduced the cleaning and nursing requirements; High-efficiency and low-resistance meltblowout, nanofiber materials and three-rejection and one-resistance medical materials are widely used in protective masks, protective suits and isolation suits, providing efficient protection for medical workers fighting against the novel coronavirus pneumonia.
