Dyeing technology for fiber garment

Abstract

The invention relates to a dyeing technology for a fiber garment. The technology comprises the following steps that 1, hot water of 80-100 DEG C is poured into a dye vat, and the fiber garment is soaked in the dye vat for 30-50 min; 2, then dye, anhydrous sodium sulphate, a levelling agent, glycerol, sodium bicarbonate, cellulose, fatty acid, a cosolvent and water are evenly mixed to form a dyeingagent, and heating and stirring are conducted for 50-60 min; 3, the fiber garment soaked in the first step is dried at 50-70 DEG C and soaked in the dyeing agent prepared in the second step, and thefiber garment is repeatedly turned over and soaked for 30-50 min; 4, the fiber garment is taken out, dried in a vacuum environment and then placed in a natural environment for standing for 2-3 h so that a finished product can be contained. The dyeing technology is simple, convenient to operate, high in color fastness and dye fixation rate and free of toxicity and harm to the human body, special odor cannot be generated, secondary pollutants cannot be generated in the preparation process, environment-friendly and clean production is achieved, and the preparation materials are low in price and wide in source.

Description

technical field [0001] The invention belongs to the technical field of garment dyeing, and in particular relates to a dyeing process of fiber garments. Background technique [0002] A large number of chemical dyes are used in the printing and dyeing industry, which has a serious impact on the environment. Currently commonly used synthetic dyes contain carcinogenic substances, which directly harm the wearer or the producer, and are irritating and allergic to the skin. In order to prevent the aggravation of environmental pollution, the number of chemical dyes banned in the world has increased from dozens to hundreds. [0003] Sodium alginate, also known as sodium alginate, kelp gum, alginate, and alginate, is a natural polysaccharide carbohydrate extracted from kelp. However, since the main raw material for the preparation of sodium alginate is kelp, not only the resources are limited, but also the cost is high. In order to promote the development of the printing and dyeing ...

Problems solved by technology

However, since the main raw material for the preparation of sodium alginate is kelp, not only the resources are limited, but also the cost is high. In order to promote the development of the printing and dyeing industry, silk, wool and cashmere blended interweaving can overcome the disadvantages of poor wrinkle resistance and easy cracking of real silk products. , improve the wearing performance of the product, and at the same time increase the variety of designs and colors of the product, and expand the wearing season, which has the practical significance of killing multiple birds with one stone.

Compared with spun silk and cashmere blended fabrics, spun silk, drawn wool, and cashmere blended fabrics use drawn wool to replace most of the cashmere, which reduces the cost, and the market price of the product is much higher than that of pure silk products, which has a broad market Foreground, but the dyeing process is difficult
