Production method of worsted shell fabric containing polyolefin elastic fibers

Abstract

The invention discloses a production method of worsted shell fabric containing polyolefin elastic fibers. The shell fabric is formed by spinning wool fibers, cashmere fibers, bamboo charcoal polyester fibers, superfine poly(butylene succinate) silk yarns and the polyolefin elastic fibers, and anti-pilling treatment, enzyme treatment and softening treatment are respectively conducted on the wool fibers and the cashmere fibers; the wool fibers, the cashmere fibers, the bamboo charcoal polyester fibers, the superfine poly(butylene succinate) silk yarns and the polyolefin elastic fibers are spun into the shell fabric according to the weight ratio of 55-75 : 12-18 : 18-28 : 12-15 : 5-8, and eventually aftertreatment is conducted on the shell fabric through a water-soluble polyurethane wool anti-shrinking agent. The production method has the advantages that damage to wool fiber products can be greatly reduced, the pilling phenomenon is reduced, the shell fabric made of the wool fibers, the cashmere fibers, the bamboo charcoal polyester fibers, the superfine poly(butylene succinate) silk yarns and the polyolefin elastic fibers as major raw materials is softer, the felting shrinking percentage is greatly reduced, and the quality of the shell fabric is better.

Description

technical field [0001] The invention relates to a production method of a fabric, in particular to a production method of a worsted wool fabric containing polyolefin elastic fibers. 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 woo...

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
