Problems solved by technology

[0006] However, the dyeing effect of natural dyes is poor, and the color fixation of the dyed fabric is low. 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 serious problems for the treatment of printing and dyeing wastewater with high salt content. It is more difficult, such as direct discharge will destroy the ecological environment and lead to soil salinization
[0007] At the same time, when natural dyes are used, some mordants containing metal ions are usually used. Although the use of mordants will improve the dyeing effect, if the mordants cannot be completely removed in post-processing, it will not only pollute the environment, but also cause pollution. It will make the shade of the fabric mostly dim, affecting the vividness and aesthetics of the dyed fabric
In addition, in order to reduce the difficulty of dyeing in the subsequent dyeing process, the fiber fabric usually needs to be pretreated before dyeing, but the current pretreatment basically uses alkaline solutions such as hydrosulfite and sodium carbonate for high temperature pretreatment, which will affect the fiber. Larger damage

Abstract

The invention discloses a dyeing and finishing process of polyester-nylon composite fiber fabric. The dyeing and finishing process of the polyester-nylon composite fiber fabric comprises pretreatment, preshaping, modification treatment, dyeing, mordant removing, soaping, fixation, finishing, drying, shaping, calendering and winding. According to the dyeing and finishing process of the polyester-nylon composite fiber fabric, helicase and alhpa-amylase are adopted to conduct pretreatment, the modification treatment is conducted before dyeing, modification is conducted on performance of the polyester-nylon fabric radically, and the dyeing rate of the fabric is increased; in the dyeing process, a large amount of alkaline matter and inorganic salt are not used, a levelling agent, substitution alkali, migration inhibitor and diffusant are added, the level-dyeing property is improved, natural dyestuff is used, therefore, environmental pollution is avoided, and requirements of green environmental protection are met; self-cleaning treatment is added in finishing, and the self-cleaning capacity, crease resistant property and fastness to washing of the fabric are improved; the whole process is environmentally friendly and free of pollution.

Description

technical field [0001] The invention relates to a dyeing and finishing process of polyester-nylon composite fiber fabric. Background technique [0002] Fiber is divided into chemical fiber and natural fiber. Natural fiber refers to the fiber that exists and grows in nature and has textile value. Chemical fiber is made of natural polymer compound or artificially synthesized polymer compound. Fibers with textile properties produced by silk and post-processing processes. Chemical fibers have the advantages of light resistance, wear resistance, easy washing and drying, no mildew, and no moths. They are widely used in the manufacture of clothing fabrics, filter cloths, and conveyor belts. , hoses, ropes, fishing nets, electrical insulation wires, medical sutures, tire cords and parachutes etc. [0003] Polyester nylon is a kind of chemical composite fiber, including polyester and nylon. It has the characteristics of polyester and nylon at the same time, so it can be widely used ...
