Applied Research On Producting Colored Silk By Feeding Additive To Silkworm, Bombyx Mori

As Queen of silk fibers, the silk products will be subject to chemical bleaching process colors. Chemical bleaching process will emit large quantities of waste water, causeing environmental pollution, and the color of the products is not bright enough. The natural color of silkworm is a kind of silkworm which spit out the colorful silk itself. Textiles made of silk color, without bleaching, dyeing and printing processing, it has a natural color, and fabric more soft and elastic. There is only yellow cocoon and green cocoon in nature. In order to enrich the natural color of silk colors, producting three primary colore silk is researched by feeding additive to silkworm, which can promote the basic research of the colored silk.This paper is divider into three parts, mainly about the resraech on producing colored silk by feeding additive to silkworm.The first part is the applied research on producing colorful silk by feeding additive to silkworm in Rudong and Sheyang. Main content: by our lab's research, and extender to rural areas to a range of issues involved, propose meaningful solutions by design experiments in the lab, by which I can proved the feasibility of the methods. Then the new method is extender to rural areas. Make a series of investigations on the cocoons there. With the data, we can analyze the differences between theory and practice of some elaboration.The second part is the composite silk color development. Main elements are:1 Mix the pigment which can find out successfully to make colorful cocoon into the natured colorful silkworms with the method of feeding additive. The pigment and the nature color can be complex and there is no conflict, resulting in expected composite color.2 With increasing concentrations of added pigments, the composite color also changed, so the color is adjustable. The third part is about the research on a new cocooning color. This experiment by adding food coloring additive method of producing colored silk. Main content: 1 access to a large number of documents, select 4 kinds of food coloring organic pigments. 2 these pigments dubbed 0.1% of the solution, the uniform will be sprayer on the mulberry silkworm feeding fifth instar strong, three times a day until nest, make the research on the cocoon color; Finally, make the research on the impact of their offspring with the color additive.The results are as follows:1 A cocoon in the rural extension and the lab have been consistent with the data base shows that the lab method for large-scale application. However, the degumming experiments in the lab found that the red cocoon turns into white when in the hot alkali solution. So we must avoid using of lye degumming in the production.2 Composite color silk research is very desirable, the used silkworm is supplied by Professor Yang Hu Sima. The text finds out that the pigment and natural color can be well compound and the complex color is adjustable.3 Research on the new pigment, through a series of failures. The blue pigment in the 4 kinds of pigments is the success one. Its chemical structure is similar to the red pigment. The structure may be related to the intestines to the blood and the silk gland of some protein binding, and thus to the silk gland. In the detection of their offspring, the eggs can be normal, and the eggs show blue color. Due to time constraints, this is only on the development of blue pigment in the test, the silkworm's survival is not satisfactory, the deeper the color, the greater the toxicity of the silkworm, the lower with the concentration of the solution . Optimizing the formulation of pigment road is still a long way to go.
