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 colo

Abstract

The invention discloses a dyeing and finishing process for a mulberry silk fabric. The process comprises the following steps: pretreatment; pre-setting; modification; dyeing; soaping; dye fixation; afterfinishing; drying; setting; calendering; and rolling. According to the invention, supersonic waves are used for pretreatment, and the step of modification is increased; and natural dyes instead of a great amount of alkaline substances and inorganic salts are employed in dyeing, and rosin powder is added as a fixing agent, so dye fixation effect is reinforced, environmental pollution is avoided, and requirements of greenness and environmental protection are met. Through treatment by using the process, the mulberry silk fabric with high rubbing fastness and high dye fixation degree can be obtained.

Description

technical field [0001] The invention relates to a dyeing and finishing process of mulberry silk fiber fabric. 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. Mulberry silk belongs to a kind of natural fiber, to be precise, it is a kind of natural protein fiber. Mulberry silk fiber is a high-grade textile raw material, the fiber is thin and soft, and has...
