Problems solved by technology

[0003] Silk fibers are bleached after degumming to remove natural colored matter, otherwise it will affect the dyeing and change the final color of the dyeing. At present, silk bleaching is mainly carried out with various chemical bleaching agents, the most commonly used is H 2 o 2 , the treatment concentration is generally 30%, this treatment concentration will damage the silk to a certain extent during the bleaching process, and there are also pollution problems

Abstract

The invention relates to the technical field of natural silk treatment and particularly relates to a rapid and energy-saving bleaching method of natural silk. The method comprises the following specific treatment steps: adding cane sugar, monosodium glutamate, urea and sodium iodide into potato raw juice, carrying out mixing to obtain a mixture as an activating solution, inoculating the mixture with geotrichum candidum for activation, uniformly spraying the activating solution to the natural silk for treatment, then, feeding the natural silk into a 3% H2O2 solution for soaking for 5 to 7 minutes, fishing out the natural silk, carrying out centrifugation and water washing, draining the treated natural silk, and then, baking the natural silk in a baking room. According to the method, the natural silk with a relatively high whiteness index can be obtained in case of low-concentration treatment, the bleaching cost is reduced, and the pollution to environments caused by bleaching is also reduced.

Description

technical field [0001] The invention relates to the technical field of silk processing, in particular to a fast and energy-saving bleaching method for silk. Background technique [0002] Silk is the lightest, softest and thinnest natural fiber in nature. It can easily return to its original shape after the external force is removed. The silk quilt is made of high-quality silk, with a novel fiber structure to allow water vapor to circulate freely. Coupled with the unique air permeability and moisture permeability of silk itself, the silk quilt feels smoother, cool but not warm, warm but not dry. Mulberry silk is mainly composed of animal protein, rich in 18 kinds of amino acids necessary for the human body, can promote the vitality of skin cells, prevent vascular sclerosis, long-term use can prevent skin aging, and has a special antipruritic effect on certain skin diseases. Inflammation, frozen shoulder, and asthma have certain health care effects. Known as "the second s...
