Abstract

The invention relates to a preparation method of a permeable reinforced raw silk processing agent. Processing agents sold in the present market generally have the disadvantages of small raw silk breaking strength, bad cohesion, bad fabric breathability, difficult wastewater processing the like. The preparation method of the invention comprises the following steps: adding graphite powder, sodium nitrate and concentrated sulfuric acid to potassium permanganate in an ice bath environment; reacting above substances in a 35DEG C water bath, heating, washing, applying ultrasonic processing, carrying out centrifugal filtration and vacuum drying, carrying out ultrasonic processing on the resulting substance with N,N-dimethyl formamide, ethylene diamine and dicyclohexylcarbodiimide, adding waterless ethanol, allowing the resulting solution to stand overnight, and carrying out vacuum drying to obtain amino modified graphene oxide; and stir-reacting the amino modified graphene oxide, oxidized polyethlene wax, lanolin, oxidized rapeseed oil, oxidized lard, an emulsifier OS-15h and an emulsifier 1631 to obtain the permeable reinforced raw silk processing agent. The strength, the surface lustereffect, the smooth and soft performances, the antistatic performance, the flame retardation and the like of raw silk processed with the permeable reinforced raw silk processing agent of the inventionare greatly improved.

Description

technical field [0001] The invention relates to a preparation method of a textile treatment agent, in particular to a preparation method of a water-permeable enhanced raw silk treatment agent. Background technique [0002] Raw silk must be impregnated before weaving. The purpose is to soften the sericin of raw silk and endow it with smoothness, abrasion resistance and softness. At the same time, the impregnating agent penetrates into the raw silk and makes the raw silk retract, which will increase the tensile strength and elongation at break of the raw silk, reduce the internal stress in the silk reeling process, and eliminate the static electricity generated in the preparation process and weaving process , Reduce or avoid fluffing and broken ends in the manufacturing process and improve fabric quality. [0003] At present, the treatment agents sold on the market generally have the disadvantages of little improvement in the breaking strength of raw silk, poor cohesion perf...
