Problems solved by technology

[0003] However, the pigment of natural colored silk is mainly distributed in sericin. If the sericin of natural colored silk is removed by conventional degumming processing methods, the natural pigment will be dissolved in the degumming solution, and it is difficult to retain the natural pigment , so that the natural colored silk fabric loses its color, which greatly affects its hygroscopicity, handle and gloss, and thus affects its wearing performance and value.

Abstract

The invention relates to the technical field of textile industry, and in particular relates to a method for preparing a pigment for improving natural colorful silk fibers. The preparation method comprises the following steps: (1) raw silk treatment, namely firstly, soaking natural colorful silks into a solution which contains 5-15% of a grafting agent, 1-5% of potassium persulfate and anhydrous sodium sulphate of 30-40g/L, wherein the bath ratio is 1:(30-50), and regulating the PH value to be 3 by utilizing citric acid, wherein the treatment temperature is 70-90 DEG C, and the treatment time is 50-70 minutes; and (2) steaming, namely steaming the treated natural colorful silks at 100-120 DEG C for 60-80 minutes by utilizing a steamer. According to the method, the raw silks are treated firstly, the saturation degree of silk fibers is reduced through the sequential steps such as steaming, glutaric dialdehyde treating, refining and alkali washing, wherein citric acid is served as an acid medium, the color characteristic value variation of the silk fibers is small, the color and handfeel performances of natural color silk fabrics are improved, and finally, the wearing value of the natural colorful silk fibers is improved.

Description

technical field [0001] The invention relates to the technical field of textile industry processing, in particular to a preparation method for improving natural colored silk fiber pigments. Background technique [0002] Nowadays, natural colored silk fiber is a new silk variety developed in recent years. It mainly transfers the original and excellent colored cocoon genes at home and abroad to high-yield and high-quality white cocoon varieties through gene recombination, and breeds high-yield colored cocoons. Silkworm varieties, and finally get colored silk varieties. Moreover, natural colored silk avoids the harm of chemically synthesized dyes to the human body and the environment, making silk products more natural. [0003] However, the pigment of natural colored silk is mainly distributed in sericin. If the sericin of natural colored silk is removed by conventional degumming processing methods, the natural pigment will be dissolved in the degumming solution, and it is diff...
