Processing technology for smooth and non-shrinkable wool yarns

Abstract

The invention discloses processing technology for smooth and non-shrinkable wool yarns, and belongs to the technical field of performance processing for textile yarns. The processing technology comprises the following steps of: analyzing mechanical and physical properties of wool yarns sold in the market, and humidifying the wool yarns in a yarn processor; performing socking, preprocessing, rinsing, biochemical preparation processing and neutralizing on the wool yarns; and adding a softening and dispersing agent consisting of a silicone softening agent, fatty alcohol-polyoxyethylene ether, amide ether, double-chain esterquat for function processing, drying, and packaging finished products. For the wool yarns processed by the technology, the density and thickness of scales are all reduced, so felt contraction is reduced, and the itchy feeling of the wool is removed on the basis of maintaining the special elasticity and warmness of fibers. Meanwhile, various adverse effects in the spinning process after the wool fibers are subjected to fiber loosening processing in the industry in the prior art are overcome. The wool yarns processed by the technology are smooth, soft, non-shrinkable and non-itchy, and have bright and uniform colors and lasting effect.

Description

technical field [0001] The invention belongs to the technical field of performance treatment of textile yarns, and in particular relates to a silky and shrink-proof performance treatment process of wool yarns. Background technique [0002] The research on the properties of wool fiber has been done for a long time, and there are many methods. Most of them remove or weaken the scale layer of wool fiber by physical and chemical methods, so as to improve its physical, mechanical and chemical properties, improve the wearability of the fiber, and obtain higher added value. Compared with ordinary wool, the treated wool fiber is mainly The characteristics are shrink-proof, machine washable, and anti-pilling, which are more and more favored by consumers in recent years.

Problems solved by technology

[0003] In the traditional wool fiber performance treatment process, the chlorination method is generally used. This method has a better treatment effect and is the most economical but has pollution problems; there is also a resin method. The function of the resin is to deposit a layer on the wool surface. The resin film smoothes the surface of wool scales and reduces the surface friction effect of fibers. Second, the active groups on the polymer molecular chains chemically combine with the active groups on the fiber surface to crosslink the fibers and prevent the friction between fibers. Free movement, the fibers treated by this method feel rough, and the resin is easy to fall off in the subsequent process, and the effect cannot last

At present, the performance treatment of wool fibers in the industry usually adopts the loose wool treatment process. The treated wool fibers are smooth, shrink-resistant, and friction is reduced, which makes the cohesion of the fibers weaken during the spinning process, and the number of broken ends increases and it is difficult to spin.
