Textile intermediate products are mainly cotton yarn cotton cloth and polyester cotton yarn polyester cotton cloth, commonly known as "two yarns and two fabrics". The largest office in China head office is the "Gauze Office". Upstream products, such as high-tech fibers, such as aramid fibers for optical fibers and bulletproof vests, ultra-high temperature resistant ceramic fibers, and hollow denatured fibers for moisture absorption and sweat absorption, are lacking in domestic research and production; Downstream products, such as high-quality dyed and printed fabrics, are closely related to the chemical industry. The development of heavy chemical industry in China is not in the forefront of the world, and the production of high-grade fabrics is not satisfactory. Where is the best silk in the world? Not in China, the land of silk, but in Italy. In fact, all Italian silks come from China. After dyeing and finishing in Italy, it is worth a hundred times. Another example is that foreign countries set up green barriers to China's textiles, and China spends a lot of foreign exchange to import environmental protection dyes every year. The solution is that on the one hand, the state should invest in the basic research of textiles, on the other hand, with the development of heavy chemical industry, the dyeing and finishing level should be improved.
