Abstract

The invention relates to a dyeing and finishing process for preparing a silk fabric with a formaldehyde-removing function. The technical problem to be solved is to provide dyeing and finishing process for a silk fabric with a formaldehyde-removing function, wherein the process can provide the fabric with the function of removing formaldehyde effectively, and the fabric has abundant colors. The technical scheme is that the finishing process for a silk fabric with a formaldehyde-removing function comprises the following steps of: 1) finishing, wherein the using amount of a tea polyphenol formaldehyde-removing finishing agent is 5%-10% of the fabric weight; 2) complexing. The dyeing and finishing process for a silk fabric with a formaldehyde-removing function comprises the following steps of: 1) dyeing, wherein a proper amount of acid dyes are used, and the using amount of the tea polyphenol formaldehyde-removing finishing agent is 5%-10% of the fabric weight; 2) complexing. The dyeing and finishing process for a silk fabric with a formaldehyde-removing function comprises the following steps of: 1) dyeing, wherein a proper amount of active dyes are used, and the using amount of the tea polyphenol formaldehyde-removing finishing agent is 5%-10% of the fabric weight; 2) soaping; 3) complexing.

Description

technical field [0001] The invention relates to a dyeing and finishing process of functional fabrics, in particular to a dyeing and finishing process of real silk fabrics with the function of removing formaldehyde. Background technique [0002] With the improvement of material living standards, indoor air pollution caused by interior decoration and decoration materials and the resulting health problems have gradually attracted widespread attention. Formaldehyde is a highly volatile organic compound with many pollution sources, high pollution concentration, and long duration. It has become the main pollutant in the decoration of new homes in our country. [0003] The harm caused by formaldehyde to human health is extremely serious. It has a strong stimulating effect on human mucous membranes and skin. When inhaled at high concentrations, severe irritation and edema of the respiratory tract will occur, the resistance of the respiratory tract will increase, and the respiratory ...
