Method for producing high-strength worsted woolen fabrics

Abstract

The invention relates to a method for producing high-strength worsted woolen fabrics. The producing method includes that a mixture of phosphate and antimony trioxide is used as an anti-pilling agent to carry out anti-pilling processing and further heighten the fiber and fabric's anti-fluff effect which is thus improved to a level of 4 to 5; a water-soluble organosilicon softener is used for softening treatment, to make wool fabric and cashmere fiber have a smoother and fuller feel; finally, the fabrics is treated by a water-soluble polyurethane wool-shrink proof agent. After this post-treatment, the felting shrinkage rate of the processed wool fabric <= 3%, which is much smaller than the standard of 8% stipulated by the International Wool Secretariat, and therefore, the comprehensive quality of the fabrics is greatly improved. Polylactic acid fiber is characterized by easy blending so as to enhance advantages and offset disadvantages of each fiber, so that the fabrics made of the mentioned fiber have higher strength and stronger capability of water-absorption and heat-preservation. In addition, the fabrics are more crisp, and beneficial to people's health and environmental protection.

Description

technical field [0001] The invention relates to a production process of a fabric, in particular to a production process of a high-strength worsted wool fabric, and belongs to the technical field of garment fabrics. 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. The wool worsted fabrics currently on the market are often due to the use of inappropriate manufacturing methods, which greatly reduces the quality of the fabrics. For example, the use of mordant dyeing process, although the color is uniform, the color fastness is good, and the cost is low, but the dyeing temperature is high, the time is lo...

AI Technical Summary

Problems solved by technology

For example, the use of mordant dyeing process, although the color is uniform, the color fastness is good, and the cost is low, but the dyeing temperature is high, the time is long, the damage to the wool is great, and the fabric resilience is poor.

For another example, the use of inappropriate finishing process will make the surface of the fabric uneven, the phenomenon of curling is serious, the shrinkage rate is large, and it is easy to fluff and pilling
