Production method of Newdal-fiber-containing spun wool fabric

Abstract

The invention discloses a production method of a Newdal-fiber-containing spun wool fabric. The fabric is spun from wool fibers, cashmere fibers, bamboo charcoal terylene fibers, superfine poly(butylene succinate) yarns and Newdal fibers. The production method comprises the following steps: respectively carrying out anti-pilling treatment, enzyme treatment and softening treatment on the wool fibers and cashmere fibers; spinning the wool fibers, cashmere fibers, bamboo charcoal terylene fibers, superfine poly(butylene succinate) yarns and Newdal fibers in a weight ratio of (55-75):(12-18):(18-28):(12-15):(5-8) into a fabric; and finally, carrying out after-treatment on the fabric by using a water-soluble polyurethane wool anti-shrinking agent. The method can greatly reduce the damage of the wool fiber product and reduce pilling; and the fabric has the advantages of softer feeling, greatly lower felting shrinkage and better quality.

Description

technical field [0001] The invention relates to a production method of fabric, in particular to a production method of worsted wool fabric containing Newdale fiber. Background technique [0002] The most important wool fiber for textile is sheep wool, which is usually called wool, or wool fiber, or wool for short. Its advantages are obvious. First, it has high water absorption and is very comfortable to wear. Second, it has warmth retention property, natural curl, and can form many stagnant air zones as a barrier. The third is durable, with very good stretchability and elastic recovery. At the same time, it also has very obvious disadvantages. It is easy to produce felting reaction, and the edges of the hair scales are hooked to each other, and they are entangled to the point that they cannot return to their original length and size. Felting reaction and milling have a great influence on the softness, luster, feel and shape memory retention function of wool fiber products...

Problems solved by technology

But the used treatment bath pH value of the modified method of this patent is 3.6-4.8, although it is weakly acidic, it still has certain damage to the woolen fabric, if the acidic substance cannot be fully removed in the finishing process, it will cause damage to the skin of the human body. Stimulate and affect health; the time used in the method is 30 minutes to 2 hours for persulfuric acid or persulfate treatment time, 30 minutes to 2 hours for compound enzyme treatment time, and 30 minutes to 2 hours for softener treatment time , therefore, the whole process takes a long time, which not only affects the production efficiency, but also is not conducive to saving energy
