There are many anti-pilling methods. Before and during dyeing, methods such as changing the structure, composition and properties of the fiber, changing the spinning process and fabric structure of the yarn, and changing the dyeing and finishing process are used, but we are generally used to fabrics and garments. Finishing after dyeing. Below is the Bedding Twill Printed Fabric Factory to tell you a few ways to prevent cloth pilling.
1 biological polishing (biological enzyme finishing)
Bio-polishing is a finishing process that uses cellulase to improve the surface of cotton fabrics in order to achieve long-lasting anti-pilling effect and increase the fabric's smoothness and softness. Bio-polishing removes the fine fibers protruding from the surface of the yarn, the fluff on the surface of the fabric is greatly reduced, and it becomes smooth without fluffing. (Enzymatic hydrolysis and mechanical shock remove the pile and fiber ends on the fabric surface, making the fabric structure clearer and brighter.) Practice has proved that this method has a long-lasting effect on reducing fluff and pilling, because the ends of the fibers are removed instead of being covered in place, but it should be noted that this method will have a certain loss of fabric strength and partial weight loss. For cotton and Polyester Twill Dyed Fabric, cellulase is used; for wool or polyester / wool blended fabric, suitable bioprotease is used for polishing. Therefore, the process conditions must be strictly controlled, or enzyme inactivation or serious damage and weight loss will be caused, and large quantities of fabrics are not suitable (there is a cylinder difference), so some knitted fabric dyeing and finishing plants are unwilling to apply this method.
2 Mild down method (mainly used for wool fabrics, such as woolen sweaters, wool knitwear)
After knitting such as woolen sweaters, the roots of wool fibers are felted in the yarn after slight shrinking, and the fibers are entangled with each other, so the coefficient of friction between the fibers is enhanced, making it difficult for the fibers to withstand friction. The yarn slips out, which reduces pilling in fabrics such as sweaters. At present, fabrics such as worsted woolen sweaters are generally slightly raised to improve their anti-pilling effect. The process is as follows: sweater infiltration-light flocking-washing-dehydration-drying.

3 resin finishing method
Resin is a variety of polymers. By using the function of resin to form a cross-linked network film on the fiber surface, the fiber surface is wrapped with a wear-resistant resin film. This resin film weakens the fiber slip; at the same time, the tree finger Evenly linked and condensed on the surface layer of the yarn, so that the fiber end is adhered to the yarn, and it is difficult to pilling when rubbing, so the pilling resistance of the sweater can be effectively improved.
The selected resin must have a large adhesion with the fiber, and at the same time it should have a certain strength. After finishing, it must have good elasticity and smooth and non-sticky feel. The adhesive film does not affect the color of the dye. Fastness and gloss. No irritation to human skin. No odor; tree finger has stable performance, convenient application, reliable and low price.
At present, ordinary resins (acrylic acid self-crosslinking tree fingers) can no longer meet the high requirements of customers for fabrics, because some anti-pilling agents (resin) have a hardened feel and reduced strength after treatment. Changes occur, and some resins must be baked at high temperatures.
The above are several tips for preventing pilling of fabrics shared by Plain Printed Cotton Fabric supplier.
