Problems solved by technology

[0002] Mulberry silk has the reputation of "fiber queen". It is loved by people because of its soft hand feeling, good moisture absorption and breathability, and a series of excellent wearing properties such as comfortable wearing; however, mulberry silk will be hydrolyzed and destroyed under the action of acid and alkali, especially for The tolerance of alkaline solution is even worse. In strong alkaline solution, mulberry silk will be significantly hydrolyzed, which will break the molecular chain of silk protein fiber, and the fiber strength will drop sharply; however, mulberry silk products will use acid, Alkali preparations are used for processing silk fabrics. For example, in the processing of silk fabrics, the "acid shrinkage" characteristics of silk are used to make shrunken fabrics, and silk is dyed with acid dyes based on the ability of silk to absorb acidic substances; A treatment method for silk acid and alkali resistance, thereby enhancing the performance of mulberry silk fabrics

Abstract

The invention belongs to the technical field of silk processing, and particularly relates to a treatment method of improving acid-base resistance of mulberry silk. The method comprises the following steps of: (1) putting the mulberry silk in a erythritol aqueous solution for heat preservation soaking, draining off the solution, fishing out the mulberry silk, performing magnetization treatment andvacuum treatment when no water drips, and (2) soaking the mulberry silk in treatment liquid, performing ultrasonic treatment, draining off the liquid, fishing out the mulberry silk, and performing freezing treatment, steam treatment and microwave drying when no water drip, wherein the treatment liquid is prepared from the following raw materials: taurine, sodium benzoate, gallic acid, chlorogenicacid, fructus momordicae polysaccharide and water. The flexibility and elasticity of a silk fiber structure are effectively improved; the surface of the silk fiber structure is covered with a compactprotection film, so that the mulberry silk can have the better acid-base resistance; the tensile property and flexibility of the mulberry silk are effectively improved under an acid-base condition; the quality of the mulberry silk is greatly improved under the acid-base condition; and the usability of the mulberry silk is improved.
