Problems solved by technology

In the process of preparing natural colored silkworm silk products through degumming, most of the pigments will be lost with the dissolution of sericin, so that the color of natural colored silkworm silk cannot be retained
[0006] The prior art discloses a variety of methods for processing, inspecting or retaining colors of natural colored silkworm silk. For example, the Chinese patent document with the application number 200410065256.7 discloses a processing method for natural colored silkworm silk, mainly by differentiating two colors. The silkworm cocoons are mixed with cocoons, and the proportion of mixed cocoons is 40% to 60% according to the particles or weight of silkworm cocoons; the difference in unwinding rate of silkworm cocoons of the two kinds of mixed cocoons is not more than 10%, and the difference in cocoon silk fineness is not more than 0.50 denier , carry out silk reeling processing after fully mixing, adopt this kind of method to produce the mulberry silk of different colors, color uniformity and texture difference, but it can not fix the color of natural silkworm silk; A test reagent for natural colored silkworm silk, the reagent is a colorless and transparent acidic solution or an acidic salt solution composed of monobasic or polybasic inorganic acids with a pH value ≤ 5.0, and the reagent can be used to distinguish silkworm cocoons, silkworm silk, and silkworm silk Natural colored and living dyed or synthetic pigment dyed or natural pigment dyed products of fabrics and other cocoon silk products, which cannot fix the color of natural silkworm silk; the Chinese patent document with application number 200510011188.0 discloses a microwave-connected natural green cocoon silk Branch color fixing method, firstly soak the natural green cocoon silk in glacial acetic acid for 2-3 minutes, remove it and squeeze it dry, then esterify it under the action of microwave with a frequency of 2450MHz and a power of 200-600W for 5-8 minutes, and wash off the excess with water. acetic acid, the green cocoon silk obtained after drying will not fade in the washing process, but in the process of using microwaves to treat silk, microwaves will penetrate silk, thus affecting the mechanical properties of silk

Abstract

The invention provides a color fixing method of natural colorful mulberry silk, which comprises the following steps: a) processing the natural colorful mulberry silk in water; and b) using acid glutaraldehyde solution to process the natural colorful mulberry silk obtained in the step a). Natural colorful mulberry raw silk serves as a raw material, first the natural colorful mulberry raw silk is processed in the water to enable sericin containing pigment to swell; and the acid glutaraldehyde solution is utilized to process the swelled natural colorful mulberry raw silk, the sericin is composedof massive amino acid containing free amino, glutaraldehyde can react with the free amino to form an annular pyridine structure, and sericin is denatured, fixed and not dissolved. Simultaneously, thepigment distributed in the sericin is also fixed and is not drained in the follow-up processing process. The natural colorful mulberry raw silk serves as the raw material, strong acids, strong alkalis and the reagents including calcium salt, lithium salt and the like are not involved in the processing process, and mechanical property of the natural colorful mulberry silk is not damaged.

Description

technical field [0001] The invention belongs to the technical field of silk, in particular to a method for fixing the color of natural colored silkworm silk. Background technique [0002] Shade, that is, color and luster, is an important indicator for evaluating the quality of fibers and fabrics. The color of general textile materials or textiles is mainly derived from synthetic dyes. The main components of synthetic dyes are toxic azo compounds, which are harmful to human body such as distortion, carcinogenic and allergenic. At present, the popular colored silk products have been produced only by chemical dyeing, which not only uses toxic synthetic dyes, but also produces a large amount of processing wastewater such as printing and dyeing, which seriously pollutes the environment. Yes, wearing close-fitting clothes will affect your health. [0003] Natural colored silkworm silk is prepared from colored cocoons of silkworms. The colored cocoons of silkworms mainly include ...
