Anti-pilling treatment method for cotton type wool knitted fabric

Abstract

The invention relates to an anti-pilling treatment method for a cotton type wool knitted fabric. The method comprises: selecting Australasian wool whose quality count is 64-80, performing stretch breaking, blending the Australasian wool with blend fibers or performing pure spinning, to obtain yarns, weaving, when a fabric is off a loom, cooking cloth and dehydrating, then scotching, washing wool fabric, cleaning, and dehydrating; putting the fabric in a microwave drying setting-low temperature normal pressure plasma treatment device, firstly performing microwave drying setting, then performinglow temperature normal pressure plasma treatment; finally performing soft finishing, to obtain the anti-pilling fabric. Through pretreatment of stretch breaking, varieties of wool fibers which can beblended are greatly increased, so woolen fabrics are more enriched. The wool fibers after stretch breaking can be spun on a cotton spinning device, and wool spinning process flow is shortened. The wool fibers after stretch breaking have a series of variations on physical and mechanical properties, so microwave drying setting-low temperature normal pressure plasma treatment has more obvious effecton surface modification effect of wool fibers, and reduces felting of wool fibers and improves anti-pilling property of the fabric.

Description

technical field [0001] The invention belongs to the field of fabric treatment methods for woolen clothes, in particular to an anti-pilling treatment method for cotton-type wool knitted fabrics. Background technique [0002] Wool is a relatively precious natural animal protein fiber with its own unique structure and performance characteristics. The wool fiber is composed of three parts: the scale layer covering the outside, the cortex layer that forms the wool entity, and the opaque medulla layer in the center of the hair shaft. The scale layer covering the hair shaft is composed of flaky keratinocytes, and its shape can be divided into ring-shaped covering, tile-shaped covering or crack-like covering; the inside of the scale layer is the main part of the cortex that determines the main physical and chemical properties of wool Layer, because there are disulfide bonds and more hydrophilic groups between its macromolecular chains, the fibers have larger curls, are soft and ela...

Problems solved by technology

Since the mid-1950s, various experts and scholars have begun to study pilling, and have achieved certain results. At present, the more mature ways to improve the pilling performance of wool fabrics mainly include improving yarn twist, hairiness, and fabric texture. The more common methods such as structure and resin finishing, wool modification treatment, ozone finishing, etc. Although the more common methods have certain effects on improving the pilling performance of wool fabrics, the effect is not very obvious, and most of the finishing methods have damage to the fabric feel. and pollution issues
