Principle Analysis and Solution of Pilling

Fabric in the processing and taking the process, when subjected to external friction, such as friction is greater than the fiber strength or friction between the fibers or cohesion, the fiber ends will be pulled out to form a ring and fluff, the fabric surface to produce fluff So that the fabric lost luster. When the villi exposed to a certain length, the villi in a certain distance due to rubbing friction, repeated elongation and retraction and entangled into a ball, seriously affecting the appearance of the fabric surface.

When the fabric surface of the pompon formation, due to the different fiber breaking strength, yarn twist, fabric structure and so on, some pompon after the formation of easy to fall off, and some easy to fall off, entanglement, and easy to filth , Affecting the quality of clothing taking.

Cashmere fiber fine fineness, low strength, poor spinnability; Soybean protein fiber monofilament fine fineness, light weight, high strength, and acid and alkali resistance, moisture moisture permeability is good, with a soft feel of cashmere, silky soft luster, was As "artificial cashmere".
Soybean protein fiber and cashmere blended products have a good moisture permeability and antibacterial health care function, and showing a silky glossy, velvety feel. However, in the processing, wearing and washing process, due to the fabric and the fabric and other objects can easily produce pilling between the phenomenon of pilling, the fabric appearance significantly worse. So, how does the mechanism of soy protein fiber and cashmere fiber pilling up?

For the cashmere, soy protein fiber blended fabric, the soybean protein fiber has good strength, in the pilling and chemical fiber similar, thus exacerbating the pilling phenomenon of the fabric.
For the spinning weaving, wool fabric pilling performance should be the most important one, then, how can we effectively improve it? Here to introduce the two types of items from the pilling tester solution.1. Improve the spinning weaving process:
   Yarn with air-jet anti-pilling effect is better than ring spinning. Ring spinning, longer fibers tend to concentrate in the middle of the yarn, while the shorter ones are on the outside, resulting in pilling.
   In the process before combing, the cotton or sliver is fully combed to reduce the impurities and neps in cotton or sliver by controlling the yarn count, yarn twist, changing the fabric structure, improving the tightness, etc. Improve the fabric's anti-pilling performance, have a certain effect, but the fabric feel, appearance, etc. will be affected. Ring yarn cotton fabric singeing2. Polished:
   Bio-polishing is a finishing process used to improve the surface of cotton fabrics with cellulase to achieve lasting anti-pilling and increase the finish and softness of the fabric. Bio-polishing is to remove fine fibers that extend from the surface of the yarn.
   The hydrolysis of the enzyme and the mechanical impact of the common removal of the fabric surface of the plush and the end of the fiber, the fabric becomes clearer, more bright color, the use of bio-polishing to reduce the fabric pilling trend of lasting effect.3. Resin finishing:For cotton fabric pilling resistance, can be mainly used bio-polishing, and sometimes can be combined with singeing and resin finishing, but the singeing is not durable, focusing on governance table, resin finishing will affect the fabric feel.
