Problems solved by technology

In the dyeing process, the dyes used are divided into natural dyes and synthetic dyes. Synthetic dyes are highly polluting and meet the requirements of environmental protection. At present, more and more dyeing processes use natural dyes, but the dyeing effect of natural dyes is poor. The dyed fabric has low color fixation. In order to improve the color fixation, a large amount of soda ash and inorganic salts are usually added during the dyeing process, which brings great difficulties to the treatment of printing and dyeing wastewater with high salt content. Destroy the ecological environment and lead to soil salinization. At the same time, when using natural dyes, some heavy metal ions are usually used as mordants, which do not meet the requirements of current ecological textiles. After heavy metal ion mordant dyeing, the color of the fabric mostly becomes dim, which affects dyeing. Brightness and aesthetics of fabric
[0004] At the same time, although real silk fabrics have many of the above advantages, they are easy to wrinkle, so they need to be treated in a certain way after finishing.

Abstract

The invention discloses a silk fabric dyeing and finishing method. The silk fabric dyeing and finishing method comprises pre-treatment, pre-setting, modification treatment, dyeing, soaping, dye fixation, finishing, drying, setting, calendering and rolling. The method utilizes supersonic wave to carry out pretreatment and utilizes a modification treatment process. In dyeing, a large amount of alkaline substances and inorganic salts are avoided, natural dye is adopted, and colophony powder is used as a dye-fixing agent so that dye-fixing effects are obtained, environmental pollution is avoided and environmental protection requirements are satisfied. Through the silk fabric dyeing and finishing method, the silk fabric with high crockfastness and high dye fixation is obtained.

Description

technical field [0001] The invention relates to a dyeing and finishing 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 ...
