Abstract
Description
technical field
[0001] The invention belongs to the technical field of dyeing and finishing in the textile industry, and relates to a pretreatment process for fabric dyeing and finishing, in particular to a pretreatment process for hemp or its blended fabrics by dipping biological enzymes. Background technique
[0002] Both hemp fiber and cotton fiber are natural cellulose fibers. Compared with cotton fiber, hemp fiber has 15%-25% lower cellulose content, 5%-6% higher lignin content, and 0.9%-1.8% higher waxy content. These natural cellulose fibers, in addition to their own natural impurities, also have additional impurities such as various pulps and oil stains contaminated during processing. In the weaving process, since the warp yarns of the fabric must be sized before weaving, there are many additional impurities remaining in the woven fabric, such as polyvinyl alcohol slurry, starch slurry and other sizing. The presence of these impurities seriously affects the wetting ...
