Problems solved by technology

Slight fluffing and feathering on the surface of wool fabric can make people feel soft and plump, but if the hairiness is too long and the fur is too dense, when the length of the supporting fibers exceeds a certain range, the adjacent supporting fibers will be entangled with each other. Phenomenon, and then through the action of external force, these intertwined fibers break into free fibers, which causes more serious pilling phenomenon

Abstract

The invention discloses a method of preparing an anti-pilling finishing liquid for a worsted tweed. The method comprises the steps of preparing a sweeping agent solution, extracting wool keratin, adding an indifferent oxide steady solution and an ionic liquid, and the like. The method of preparing the anti-pilling finishing liquid for the worsted tweed is implemented by way of combining a phosphoric ionic liquid with a keratin solution, in which the hydrophilic groups of the cationic fraction in the phosphoric ionic liquid cause irreversible changes in the fabric, including dissolving part of scale layers and removing edges and corners from scales to expose more active sites on the surface of the wool; the active groups of the keratin form hydrogen bonds with the active groups of the wool to form a netted film having a certain strength on the fiber surface of the wool, with the netted film functioning in reducing the directional friction effect of the wool and the crimp elasticity of the wool, thus achieving the anti-pilling effect. In addition, the addition of the ionic liquid is conducive to decreasing the usage of the keratin.

Description

technical field [0001] The invention relates to the technical field of textile finishing liquid, in particular to a preparation method of worsted tweed anti-pilling finishing liquid. Background technique [0002] In the daily life and actual wearing and washing process, clothing materials will be subjected to continuous friction, especially on the parts that are prone to friction, there will often be serious pilling. This kind of pilling process can be attributed to: the hairiness on the surface of the fabric becomes messy; after friction and pulling by external force, more fabric hairiness is produced, and these fabric hairiness are entangled with each other to form a ball; further subjected to external force friction , so that the tethered fiber at the bottom of the pom-ball is broken, and the pom-pom on the surface of the fabric falls off. The directional friction effect caused by the wool scale layer structure and the curl elasticity of wool are the main reasons for the...
