Embodiment 1

[0029] Among them, W 2 (g) is the coated sample after washing, taking it out, drying it, and drying it to the absolute dry weight. Embodiment 1: Chemical etching weight loss pretreatment 1 of polyester fabric

[0030] (1) 50g polyester fabric is put into NaOH solution concentration 2%, ethylenediamine solution concentration 4%, in the 2500g mixed solution of tensio-active agent 1227 solution concentration 1.6%, bath ratio 1: 50, under the condition of 70 ℃, Carry out the chemical etching reduction treatment on the surface of the polyester fabric, and the treatment time is 1h. The chemical weight reduction rate of polyester fabric is 10%.

[0031] (2) Then, wash the polyester fabric after chemical reduction treatment to neutrality directly with water; or first neutralize it with acetic acid, and then wash it to neutrality with water. It is the polyester fabric to be coated and reused.

[0032] Calculate the reduction rate of chemical treatment, the calculation formula is as...

Abstract

The invention relates to a method for coating polyester fabric with fibroin composite liquid, wherein it comprises: adding the polyester fabric into the mixture of NaOH solution, ethanediamine solution and surface activator 1227 solution, to chemically etch the surface of said fabric; then washing it with clean water to neutral; or neutralizing with acetic acid, then washing it with clean water to neutral; adding the fabric into fibroin composite liquid to be immerged; then using absolute ethyl alcohol or steam at 120Deg. C to crystallize it; washing it with hot water; dewatering and drying, to obtain the product. The invention uses fibroin solutoin to modify the fucntion of fabric to improve the wet adsoprtion; and it uses chemcial etch method to improve three times of wet adsorption, with static resistance.

Description

technical field [0001] The invention relates to the field of reprocessing of polyester fabrics, in particular to a method for coating silk protein combination liquid on polyester fabrics by physical and chemical methods to process new functional fabrics. Background technique [0002] Silk protein (silk fibroin, sericin) contains 18 kinds of amino acids, including 8 kinds of amino acids necessary for human body. Contains more glycine, alanine, serine and aspartic acid. Silk protein is similar to human skin keratin, and has affinity, nutrition and skin care properties for the human body. Silk protein has the function of absorbing and releasing moisture, and the human body feels comfortable. Silk protein has the property of inhibiting tyrosinase activity, so it can prevent the formation of melanin in the skin and whiten the skin. Among them, tyrosine, tryptophan, phenylalanine, etc. can effectively absorb ultraviolet rays and prevent skin damage caused by ultraviolet rays in...
