Problems solved by technology

However, polyester-cotton blending can only slightly improve the wearability of the fabric. In addition to blending and interweaving, post-finishing is also required to improve the wearability of the fabric.

Abstract

The invention provides a preparation method of a skin-friendly polyester cotton blended hemp-like fabric. The preparation method comprises the following steps of S1, preparing a soybean protein polypeptide aqueous solution; S2, preparing aloe powder; S3, preparing modified aloe powder; and S4, adding the modified aloe powder prepared in the step S3 into a soybean protein polypeptide aqueous solution, uniformly mixing to obtain a finishing solution, adding a fabric into the finishing solution, then adding acrylamide, fully stirring, and adding N, N, N', N'-tetramethylethylenediamine and ammonium persulfate to obtain the modified fabric with the surface grafted with aloe gel and soybean protein. The soybean protein polypeptide and the aloe vera gel are uniformly distributed on the surface of the fabric, the fabric is a functional fabric which is friendly to skin and has relatively good mechanical performance, and when the fabric is worn, protein and aloe vera gel are in contact with the skin of a human body, so that the wearing comfort is improved.

Description

technical field [0001] The invention relates to the field of functional modification of fabrics, in particular to a preparation method of a skin-friendly polyester-cotton hemp fabric. Background technique [0002] With the development of social economy and the gradual improvement of material living standards, people's requirements for all aspects of life have been improved, and people are no longer satisfied with food and clothing. Clothing ranks first in food, clothing, housing and transportation. As an item that people have to touch all the time, textiles are no longer just used to hide shame and cold, but pay more attention to their aesthetics, comfort and health care. Polyester fiber is an important variety in synthetic fibers, and its trade name is polyester. It is a fiber-forming high polymer made of ethylene glycol and dimethyl terephthalate through transesterification and polycondensation reactions—polyethylene terephthalate, which is made by spinning and post-proce...
