Spun silk softening agent preparation method

Abstract

The present invention discloses a spun silk softening agent preparation method, which comprises: 1) mixing 130 parts by mass of octamethyl tetrasiloxane and 43 parts by mass of polyethoxylated fatty alcohol, adding sodium hydroxide to adjust the pH value to 11, heating at a speed of 5 DEG C / min to achieve a temperature of 140 DEG C, carrying out a reaction for 8 h, cooling at a speed of 2 DEG C / min to achieve a temperature of 50 DEG C, and adding 24 parts by mass of ascorbic acid in a dropwise manner to adjust the pH value to 5 to obtain a first mixed solution; 2) obtaining a second mixed solution; 3) mixing the first mixed solution and the second mixed solution, adding sodium hydroxide to adjust the pH value to 11, heating to achieve a temperature of 90 DEG C, carrying out a reaction for 6 h, and cooling at a speed of 1 DEG C / min to achieve a room temperature; and 4) adding 1-2 parts by mass of ethylene glycol monostearate, 1 part by mass of hydroxypropyl methyl cellulose, 1 part by mass of sodium carbonate, 15 parts by mass of an amino silane coupling agent and 16 parts by mass of citric acid, and uniformly stirring to obtain the spun silk softening agent. The prepared spun silk softening agent is the non-ionic softening agent and has low environmental pollution, wherein the treated spun silk has characteristics of good bulkiness and good softness.

Description

technical field

[0001] The invention relates to a preparation method of silk softener. Background technique

[0002] The existing silk softener mainly uses aminocarboxyl silicone oil emulsion, and aminocarboxyl silicone oil emulsion is mainly synthesized by anion chemical industry, contains a large amount of anions and soap inside, so it pollutes the environment more. And because of the material properties of spun silk, the effect of general softening agents on spun silk is not ideal. Contents of the invention

[0003] The object of the present invention is to provide a preparation method of a spun silk softener. The spun silk softener prepared by the method is non-ionic, has little environmental pollution, and the treated spun silk has good bulkiness and softness.

[0004] In order to achieve the above object, the technical solution of the present invention is to design a kind of preparation method of silk softening agent, comprising the steps:

[0005] 1) Mix 130 parts...
