On July 28, women workers at Ankang Wo Si Silk Factory in Shaanxi Province are pleased to organize and package the freshly-drawn natural colored silk cocoon, marking a breakthrough in the technology that has moved from the laboratory to production. Reeling women in the just out of color silk finishing packing This technology is ankang college sericulture laboratory director, associate professor Hu Beili use "silkworm is domesticated from the wild silkworm" theory, found in 1998, all over the well-being of the Qinling and Palestinian Mountains Wild silkworms, which have been eliminated as pests, have a very good utilization value. They were first cultivated for trial at home. After more than ten years of arduous efforts, wild silkworms were used to obtain natural color from wild colored natural resources, The natural color cocoons of dozens of kinds of orange, yellow, yellow, yellow, green, light green and flesh color were detected by Xi'an Institute of Textiles and Materials. The results showed that there was no significant difference in the color of the whole cross section from the fiber outer layer to the fiber center , Fiber cross-section color and fiber appearance of the same color, natural color pigment silk more evenly distributed in silk fibroin and sericin. This spring, 12 breeds of silkworm farmers were raised for normal feeding, yielding a total of 78 kilos of cocoons and producing about the same amount of silkworms as their silkworms. Associate Professor at Ankang College, Director of Sericulture Laboratory Hu Beili introduced color cocoons and the development and cultivation of this technology. Since natural cocoon silk does not need to be dyed, it can avoid the harm of various chemical residues to the human body during the process of color addition of fabrics and avoid the printing and dyeing Water pollution, which is a "green revolution" in the textile field. Natural color silk cocoon production technology both economic and social benefits, the development and utilization of their products will certainly be welcomed by the market.
