Problems solved by technology

[0003] At present, there are two main methods of anti-felting finishing technology: one is the oxidation method, which mainly damages the structure of wool scales, reduces its directional friction effect, and reduces the one-way movement and entanglement ability of fibers. This method is easy to affect the mechanical properties of wool fabrics Damage, affecting the performance of the product

Abstract

The invention provides a method for finishing machine washable wool fabrics. The method comprises the following steps: performing reduced pretreatment on wool fabrics by adopting an oxidizing agent todamage the scale layer of wool fibers to a certain degree, so that the orientation friction effect of the wool fibers is further reduced, and the felting shrinkage of the fabrics is reduced; performing repair incremental treatment with a keratin solution under a certain conditions, and forming a coating effect on the surface of the wool fibers, so that the apparent structure of the wool fibers isfurther smoothened, the differential friction phenomenon is improved, and the felting shrinkage of the product is reduced; drying to obtain the wool fabric, wherein the felting shrinkage is less than5%, and the 'machine washable' standard can be reached. The wool fabric finished by the technology is small in mechanical property damage, is weak in influence of performances such as hand feeling, moisture permeation, breathability and the like, and has wide application value.

Description

technical field [0001] The invention relates to the technical field of textile functional finishing, in particular to a finishing method for machine-washable wool fabrics. Background technique [0002] Wool fabric is repeatedly extruded by mechanical external force under the action of damp heat and chemical reagents, and the fiber aggregate gradually shrinks and interpenetrates and entangles with each other to become felted, which is called fluffing. Flocking gives wool fabrics excellent warmth retention, bulkiness, and elasticity, and at the same time, it is easy to cause wool fabrics to shrink during washing, which in turn affects their wearing performance. How to keep woolen fabrics with excellent properties without feeling shrunk during washing (i.e. "shrinkproof finishing of woolen fabrics") has become a hotspot in the wool spinning industry. [0003] At present, there are two main methods of anti-felting finishing technology: one is the oxidation method, which mainly ...
