Abstract

The invention provides a process for ferric salt after-mordanting of a real silk fabric by using a henna pigment. The process comprises the steps of dyeing and after-mordanting. The real silk fabric obtained by using the process has 5-grade crockfastness, 5-grade washing fastness, 5-grade acidic perspiration fastness and 5-grade alkaline perspiration fastness and meets the actual production and use requirements. According to the process provided by the invention, a great number of researches on the process for ferric salt after-mordanting of the real silk fabric by using the henna pigment are carried out, and conditions such as a henna pigment extraction process, a dyeing method, a dyeing temperature, the pH value of a dye bath, the dyeing time and mordanting additives as well as the mutual influences among the conditions are researched, so that a dyeing process capable of meeting the actual production and use requirements can be obtained.

Description

technical field [0001] The invention relates to the field of textiles, in particular to an iron salt post-mordant dyeing process of henna pigment on silk fabrics. Background technique [0002] When dyes are produced by traditional methods in synthetic dye factories, almost all unit processing and operations produce many toxic substances, and these toxic substances enter the ecosystem without exception. The society is increasingly emphasizing the safety of workers in the production process of synthetic dyes and the production must be friendly to the environment. Simultaneously, important resources such as oil and coal, which are needed for the production of synthetic dyes, will be greatly reduced, and more and more carcinogens from synthetic dyes have been found, which seriously affect human health. Therefore, it is imperative to research and develop natural vegetable dyes. [0003] The dyes from natural plants have good luster and low toxicity, and because they come from n...
