Problems solved by technology

[0003] Polyester is an important part of chemical fibers. Due to the physical and chemical properties of polyester itself, polyester dyeing usually requires high temperature and high pressure, so chemical dyeing is usually used, but chemical dyes are highly polluting to the environment. In order to reduce environmental pollution, research has begun to use natural dyes. dyes, but natural dyes usually need to be dyed at a lower temperature, and the dyeing effect of natural dyes is poor, and the dyed fabric has low color fixation. In order to improve the color fixation, a large amount of dyeing is usually added during the dyeing process Soda ash and inorganic salts, which bring great difficulty to the treatment of printing and dyeing wastewate

Abstract

The invention discloses a high-fixation high-flame retardation polyester fabric dyeing and finishing technology. The technology comprises pre-treatment, pre-setting, modification treatment, dyeing, soaping, dye fixation, after finishing, drying, setting, calendering and rolling. Supersonic wave is used for pre-treatment and a modification treatment process is used. In dyeing, a lot 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 fixation effects are improved, environmental pollution is avoided and environmental protection requirements are satisfied. Through modification and flame retardation treatment on the fabric by montmorillonite, fabric fire resistance is high. Through the dyeing and finishing technology, the high-fixation high-flame retardation polyester fabric is obtained.

Description

technical field [0001] The invention relates to a dyeing and finishing process of polyester fabric with high color fixation and high flame retardancy. Background technique [0002] Fibers are divided into chemical fibers and natural fibers. Natural fibers refer to fibers that exist and grow in nature and have textile value; chemical fibers use natural polymers or artificially synthesized polymers as raw materials. Fibers with textile properties produced by silk and post-treatment processes. Chemical fibers have 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. [0003] Polyester is an important part of chemical fibers. Due to the physical and chemical properties of polyester itself, polyester dyeing usually requires high temperature and...
