Finishing agent composition for cotton-silk fabrics and processing method of cotton-silk easy-care shirt

Abstract

The invention discloses a finishing agent composition for cotton-silk fabrics. The finishing agent composition comprises the following ingredients by weight: 120 to 180 parts of dihydroxy ethylene-urea resin, 10 to 60 parts of a powerful protecting agent, 10 to 50 parts of a smoothing agent, 30 to 80 parts of a softening agent, 10 to 25 parts of a catalyst, 5 to 10 parts of an anti-fraying agent, 1 to 5 parts of a penetrating agent, and 5 to 10 parts of a formaldehyde scavenger. The invention further provides a processing method of a cotton-silk easy-care shirt. The processing method of the cotton-silk shirt garment comprises the following steps: prewashing, drying, material spraying, pre-drying, pressing, baking, purified water washing, drying and moisture regaining, wherein the finishing agent composition is uniformly applied onto the cotton-silk easy-care shirt in the material spraying step. The finishing agent composition is used for finishing process of the cotton-silk fabrics, and can be used for overcoming the defect that the anti-sliding property of the cotton-silk fabrics is lowered after conventional easy-care treatment, reserving the own moisture permeability, air permeability and natural drapability of the cotton-silk fabrics, and enabling the cotton-silk fabrics to have relatively high easy-care property. Therefore, people can wear the shirt comfortably, and the shirt is easy to care. Moreover, the formaldehyde content of the finished cotton-silk easy-care shirt can be lower than the national standard.

Description

technical field [0001] The invention relates to the field of garment making, in particular to a finishing agent composition for cotton silk fabrics and a processing method for cotton silk non-ironing shirts. Background technique [0002] The silk fabric processed and woven from silk fiber has soft color, good drapability, moisture permeability, softness and smoothness, elegant and luxurious appearance and good wearing comfort, and the real silk fabric is woven from natural protein fiber , has a certain health care. At the same time, due to its high dry wrinkle recovery angle, these excellent properties make silk fabric one of the most popular high-quality spinning materials. However, since there is no chemical cross-linking between the protein macromolecules of real silk, when the silk fiber absorbs water and swells, the salt bond breaks. When it works, the molecular chains are prone to relative slippage, and when the external force is removed, there is not enough binding ...

AI Technical Summary

Problems solved by technology

However, since there is no chemical cross-linking between the protein macromolecules of real silk, when the silk fiber absorbs water and swells, the salt bond breaks. When acting, the molecular chain is easy to slip relative to each other, and when the external force is removed, there is not enough binding force between the molecules to make it return to its original position, which makes the wet wrinkle resistance of silk fabrics very poor, which greatly affects the practical effect of clothes

This is a serious shortcoming of silk fabrics, which brings a lot of inconvenience to the wearing of silk, so it is necessary to carry out anti-wrinkle finishing on silk fabrics

[0003] However, the relatively mature anti-wrinkle finishing agents are mainly anti-wrinkle finishing agents for cotton. Under certain conditions, this type of finishing agent is easy to quickly cross-link with -OH on cotton, so as to achieve the effect of non-ironing. When it acts on silk fabrics , the reactive groups on the finishing agent are difficult to react with -NH on the silk cellulose 2 and other active groups are cross-linked, so special reaction systems and process conditions are required

In addition, due to the natural smoothness of silk, the anti-slip performance of the fabric itself is poor, especially in the non-ironing finishing process, a certain amount of silicone oil softener is added to achieve a better hand feeling, which exacerbates this defect. Therefore, a special finishing agent composition is also required for finishing

In addition, due to the existence of silk, compared with pure cotton fabrics, the proportion of cotton is reduced. In order to ensure the flatness of the fabric after ironing, the amount of resin is increased, and the degree of effective cross-linking is reduced, resulting in the increase of free formaldehyde content after fabric finishing. question
