Problems solved by technology

However, in order to improve the fastness of dyed fabrics, natural dyes are currently dyed with mordant dyeing. The mordants used are generally heavy metal ions, which do not meet the requirements of current ecological textiles, and the shade of fabrics after heavy metal ion mordant dyeing mostly becomes dim, affecting Brightness and aesthetics of dyed fabrics

Embodiment 1

[0041] A kind of dyeing process of real silk fabric, comprises the following steps:

[0042] (1) Pretreatment: Pretreatment of chemical fiber, specifically: 1 g / L urea, 4.5 g / L TF-104M phosphate-free neutral deoiling spirit, 1 g / L sodium dodecylbenzenesulfonate, 60 % hydrogen peroxide 2 g / L, oxidative desizing agent OS 0.8 g / L, treated in a 30°C water bath for 2-3 minutes, the bath ratio is 20:1, and then the water bath is heated up at a rate of 2.5°C / min. After reaching 90°C, keep it at this temperature for 30-40min, and then lower the temperature of the water bath at a rate of 1.5°C / min. When the temperature drops to 60°C, discharge the treated wastewater, and then re-inject clean water to rinse at room temperature until The lotion is neutral and finally dried;

[0043] (2) Pre-setting: the pre-setting process is performed on the chemical fiber through the pre-setting machine. During the pre-setting process, the setting temperature is 160°C, the speed is 20m / min, and the ov...

Abstract

The invention provides a process for dyeing a silk fabric. The process comprises the steps of pre-treatment, pre-shaping, modifying treatment, dyeing, soaping, color fixing, post-arrangement, drying, shaping, calendering and rolling. According to the method, the fabric is modified in advance by chitosan to improve the dyeing rate, and the difficulty of the subsequent dyeing step is reduced; in the dyeing step, the chitosan is used as a mordant, and mangosteen hull serving as a natural dye is used and is free of poison and environmentally friendly; the dyeing firmness is good by additionally arranging the soaping and color fixing steps, environment-friendly formaldehyde-free TCD-R is adopted in the color fixing step, color-fixed fibers are stepwise dried, so that the fiber firmness degree is greatly improved; the post-arrangement process is additionally added, so that the color firmness and softness of the fabric is improved, the roughness of the fabric is reduced, and the fabric is fluffy and elastic.

Description

technical field [0001] The invention relates to a dyeing process of real silk fabrics. Background technique [0002] Fibers are divided into chemical fibers and natural fibers. Chemical fibers are fibers with textile properties that are made from natural polymers or artificially synthesized polymers through the processes of preparing spinning dope, spinning and post-treatment. It has the advantages of light resistance, wear resistance, easy washing and drying, no mildew and no moths. Widely used in the manufacture of clothing fabrics, filter cloths, conveyor belts, hoses, ropes, fishing nets, electrical insulation wires, medical sutures, tire cords and parachutes, etc. Natural fiber refers to the fiber that exists and grows in nature and has textile value. Silk is a kind of natural fiber. To be precise, it is a kind of natural protein fiber. And other properties, so it is also widely used in the textile field of clothing manufacturing. [0003] Dyeing is an important trea...
