Problems solved by technology

[0005] 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
[0006] 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 low-temperature dyeing and finishing technology for bamboo fiber fabric. The low-temperature dyeing and finishing technology includes the steps of pretreatment, preshaping, modification treatment, dyeing, mordant removal, soaping, color fixation, after finishing, drying, shaping, calendering and rolling. Helicase, scouring enzyme and alpha-amylase are adopted for pretreatment, modification treatment is adopted before dyeing, the performance of the bamboo fiber fabric is modified fundamentally, and the dye-uptake rate of the fabric is increased; as in the dyeing working procedure, alkaline substance and inorganic salts are not used in quantity, and a levelling agent is added, the dyeing levelness is improved; environment pollution is avoided by using natural dyestuff, which meets the requirement for environmental protection; as self-cleaning treatment is added in after treatment, the self-cleaning capacity, crease-resistant performance and wash-resisting firmness of the fabric are improved; crease-resistant finishing is added, and therefore the crease-resistant performance of the fabric is improved; the whole technology is environmentally friendly and free from pollution.

Description

technical field [0001] The invention relates to a low-temperature dyeing and finishing process for bamboo fiber fabrics. 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] Bamboo fiber is a cellulose fiber extracted from naturally growing bamboo, and it is the fifth largest natural fiber after cotton, hemp, wool and silk. Bamboo fiber has the charac...
