Problems solved by technology

[0002] Bamboo viscose fiber is a new type of regenerated cellulose fiber produced by viscose spinning process using natural bamboo as raw material. The surface of bamboo viscose fiber is shiny, the fabric feels smooth, good drapability, moisture absorption and breathability, and has antibacterial and deodorizing properties. And anti-ultraviolet function, excellent wearing performance, it is a high-grade summer clothing fabric, which meets people's demand for summer clothing. Bamboo viscose fiber fabric is favored by consumers for its excellent wearing performance, and the market demand and sales prospects are promising. The application number is CN200710070785 .X discloses a dyeing and finishing process of bamboo fiber, which sequentially includes the steps of enzymatic desizing, singeing, oxygen bleaching, dehairing enzyme finishing, dyeing, and post-finishing. It is carried out on the machine, which simplifies the technological process and saves energy. The hair-removing enzyme finishing after oxygen bleaching improves the color and gloss of the product. The occurrence of injury and other phenomena can reliably guarantee the product quality. The dosage of hydrogen peroxide is controlled to 3.5g / L, and the pH value does not need to be adjusted, which reduces the difficulty of process control. However, the bamboo fiber fabric produced by this process is relatively hard, moisture-absorbing and breathable. sex is also poor

Abstract

The invention discloses a dyeing process of bamboo viscose fiber, and relates to the technical field of bamboo fiber fabric production. The process comprises five process steps of singeing, pretreatment, dyeing, post treatment and pre-shrinkage. By optimizing the speed and the gasoline quantity, the singeing effect is good; in the pretreatment process, a mixed solution of caustic soda and hydrogen peroxide is used as a rinsing solution; the oxygen bleaching effect is improved; in addition, through the later stage puffing, swelling and fabric slurry and impurity degradation, cotton impurities are removed through steam steaming and water washing; the cotton impurity removal rate is high; the cloth damage is small; in the dyeing work procedure, the dyeing is sufficient; the effect is good; in addition, a cold batch dyeing process is used; the energy source consumption is reduced; the production efficiency is improved; the whole technical process is simple; the technical parameter controllability is good; the texture of the dyed fabric is soft; the moisture absorption and ventilation performance is good.
