A kind of tussah silk functional treatment agent and treatment method

Abstract

The invention proposes a functional treatment agent for tussah silk and a treatment method thereof. The functional treatment agent for tussah silk comprises the following raw materials in parts by weight: 0.7-1.5 parts of sodium carbonate, 2.8-3.2 parts of sodium lignosulfonate, 0.3-0.5 parts of iso Tridecyl alcohol polyoxyethylene ether, 0.2-0.5 part of L-malic acid, 0.1-0.3 part of silicon dioxide with a particle size of 30-50nm and 0.05-0.1 part of nano-titanium dioxide. The invention not only retains low residual glue rate and residual oil rate, but also ensures good mechanical strength, bulkiness and antibacterial properties of silk, realizes weight gain of silk, and has good ultraviolet resistance and water resistance.

Description

technical field [0001] The invention relates to the technical field of tussah silk processing, in particular to a tussah silk functional treatment agent and a treatment method. Background technique [0002] Tussah silk has the characteristics of rough ore, skin-friendly, breathable, and natural. It is composed of two silk fibroin wrapped with sericin. Sericin plays a role in protecting and bonding silk fibers to silk fibroin. Tussah silk mainly includes the following components: Silk fibroin 80-85%, sericin 12-16%, plain color, wax, carbohydrate 0.5-1.3%, inorganic matter 2.5-3.2%, sericin is composed of three or four layers of sericin with different solubility Among them, pigments, oil waxes and inorganic substances mainly exist in sericin. The sericin of tussah silk and silk fibroin are closely combined, and the water solubility of tussah silk sericin is not as good as that of mulberry silk sericin. In the traditional processing of tussah silk, there are problems such as ...

AI Technical Summary

Problems solved by technology

In the traditional processing of tussah silk, there are problems such as difficulty in removing oil, brittleness, yellowing, wrinkling, and low fiber breaking strength. In order to ensure the strength of the fiber and avoid brittleness and breakage, the existing processing method Usually it will increase the retention of sericin to avoid excessive degumming and damage to silk fibroin, but when the retention of sericin is high, it will affect the luster of silk, and silk products are easy to decolorize, harden and turn yellow

[0003] In addition, tussah silk protein contains amino acids such as tryptophan and tyrosine that can absorb ultraviolet rays, which make it have a certain degree of anti-ultraviolet function. However, under the light, tussah silk fabrics are prone to yellowing and brittleness after absorbing ultraviolet rays. , and with the improvement of people's living standards, higher requirements are put forward for the characteristics of silk products, such as antibacterial, etc.
