Fabric knowledge: anti pilling finishing methods

The source:adminTime:2015-05-22

Anti pilling method more, before dyeing, dyeing method has such as changing the fiber structure, composition and properties, the change of yarn spinning and weaving structure, change the dyeing and finishing process such as, but we generally used in fabric and garment dyeing finishing, the methods are:

1 biological polishing (biological enzyme finishing)

Bio polishing is to improve the surface finish of cotton fabric with cellulase, in order to achieve the anti pilling effect lasting, increase the fabric smoothness and softness. The removal of fine fibers projecting from the surface of the yarn biopolishing, fabric surface villi is greatly reduced, and will not become smooth and pilling. (enzyme hydrolysis and mechanical the impact of the removal of common and plush fabric surface with the tip, make the fabric become more clear, more bright color). The practice proves that this method is durable to reduce pilling effect, because fiber endings were removed and not in place to be covered, but it should be noted that this method will have on fabric strength the loss and partial loss.

The cotton and polyester / cellulose fiber blended fabric was treated by cellulase, wool or polyester / wool blend fabric was treated by using the suitable biological protease.. It is necessary to strictly control the process conditions, otherwise it will resulted in loss of enzyme activities or serious injury, severe weight loss, and the bulk of the fabric is not very suitable for (a cylinder), so some knitted fabric dyeing and finishing plant unwilling to use this method.

2 mild method (mainly used for fulling wool fabrics, such as wool, wool knitwear)

Sweaters knitwear after mild after milling. The roots of the hair fiber within the yarn produced felt, between the fibers are entangled with each other, thus enhancing the coefficient of friction between the fibers, the fiber when subjected to friction is not easy to slide out from the yarn, and then make sweaters and other knit fabric pilling phenomenon can be reduced. At present, the general of worsted wool sweater fabric by mild felting to improve its anti pilling effect. The process is: the infiltration of the slight felting sweater - Cleaning - drying dehydration.

3 resin finishing method

Resin is a variety of polymers, use of resin in fiber surface film forming mesh chain function, the fiber surface is coated with a layer of wear-resistant resin film and the resin film make fiber slip weakening; at the same time, tree refers to the uniform hand chain condensation on the surface of the yarn, fiber end adhesion on the yarn, friction is not easy pilling, thus effectively improve of resistance to pilling of wool sweater.

Choice of resin
The selected resin and fiber have larger adhesion must be. At the same time, also should have a certain strength, finishing to have better elasticity and smooth and non sticky feeling, conjunctival stick does not affect the color of the dye fastness and gloss. No stimulation to human skin. No smell; tree refers to the stability of the performance, convenient, reliable, inexpensive.

At present, general resin (acrylic resin crosslinked by itself tree that has been unable to meet the customers demanded of fabric, because some anti pilling agent (resin) are treated handle harden, strength loss, color change, some resin must also baked at high and other issues. Abroad has been phased out and gradually developed a new generation of anti pilling agent, its main representative product is polyurethane polymer and organic silicone resin, now this kind of product has been domestic production, and has been widely used in knitwear production of anti pilling finishing.
