Silkworm cocoon silk

"Textile light" 2011 China Textile Industry Association Science and technology award has been officially approved after publicity.

A total of 121 projects came to the fore, including 10 first prize, two prize 39 and three prize 72.

From the level of winning projects, whether it is science and technology content, technology promotion efforts, or industrialization coverage, has reached a new level.

The natural colored silkworm cocoon silk product is a product that the cocoon silk industry has been expecting for nearly a hundred years. Over the years, it has been exploring for a long time at home and abroad. Although some progress has been made in some fields, it has been unable to scale production. Because of its poor color fastness and handle, it can not be made into clothing and home textiles into people's lives.

China's cocoon and silk industry leading enterprise, Xinyuan cocoon silk group Limited by Share Ltd, has been working closely with Soochow University. After ten years of unremitting efforts, the silkworm breeds have been breasted as the breakthrough point, and the high-quality raw cocoons of natural colors have been created. In the first place, the key technologies of natural colored cocoon breeding, drying, reeling, weaving, and scouring production and processing have been developed and industrialized in China, and have been at the forefront of the world in the development and utilization of natural colored silkworm cocoon silk products.

According to the project leader, natural coloured cocoons retain the characteristics of high quality animal protein fiber, such as large molecular structure, strong ventilation, light and soft, warmth retention, good moisture absorption and comfort, and comfortable clothing. Natural coloured silk contains carotenoids, lutein pigment and flavonoid pigment from mulberry leaves. It has good antibacterial, antibacterial, antioxidant and UV blocking properties, and has broad prospects for development.

The development of natural coloured silk products caters to the development trend and market demand of the "noble, fashionable and healthy" real silk products, and fills the gap of pure natural coloured silk in China.

Natural colored silk contains natural pigments that conform to the ecological standard. Its deep processed products need not be dyed to avoid pollution caused by printing and dyeing.

Just as simple as changing white into a color, scientists and technicians have worked hard for many years.

The computer aided system is used to design the natural colored cocoon silk products, and the technical problems in the production of natural colored silk, such as knitted, woven, spun silk, nap and silk floss are solved. The knitted and woven series of garments, flannelette scarves, nightgowns, silk blankets and silk floss quilts are developed and produced.

Natural color silk products with flexible texture and bright colors are produced. Natural color silk products have soaping fastness, rubbing fastness and sweat fastness above 4. The quality of products reaches the national standard of silk fabrics and the standard of ecological textiles.

This is related to genetics, material science, chemistry and textile, and is the crystallization of multi-disciplinary research and development.

Natural color cocoon technology research and development, in the lead in the establishment of natural color cocoon breeding, drying, reeling, weaving and refining production and processing system, the formation of national standards, provincial and local standards and enterprise standards, natural color deep processing technology research and development reached the international leading level, enhance the core competitiveness of China's cocoon and silk industry, breaking the natural color cocoon cultivation and natural color cocoon deep processing technical barriers blocked by Japan.

Innovative reflections

"The successful operation of the natural color silkworm cocoon silk product chain has not only increased the income of farmers, but also injected new vitality into the development of silk industry.

This shows that innovation in textile materials is really important. "
