How to improve the abrasion resistance of textile fabrics?

Textile fabric abrasion resistance tester is mainly applied to the degree of pilling of various fabrics under slight pressure and the method of determining the abrasion resistance and pilling level of fine book-like cotton, linen and silk woven fabrics. Testing the abrasion resistance of the fabric is only one way, the key is to fundamentally improve the abrasion resistance of the fabric. The following, Wenzhou inter high technology department briefly for you to introduce, improve the abrasion resistance of the fabric method

1, from the aspect of the nature of the fiber: the main nature of the impact of the abrasion resistance of the fiber is the physical properties of the fiber tensile, bending and shear. From the fiber type comparison, abrasion resistance size: nylon > polypropylene > vinylon > ethylene spandex > polyester > acrylic > chlorine spandex > wool > silk > cotton > hemp > rich fiber > copper ammonia fiber > viscose fiber > vinyl fiber > acetate fiber > glass fiber. Comparing from the fiber structure, the abrasion resistance of round cross-sectional structure fiber is higher than the strength of shaped fiber; the finer the fiber is, the worse the abrasion resistance is. So in order to improve the wear resistance need to try to choose good wear resistance of round cross-sectional fibers.

2, from the yarn category: the wear resistance of yarn is closely related to the structure of yarn. Different spinning methods, different ways of winding fibers in the yarn, and different sizes of holding force between fibers also have different wear resistance. Traditional ring spinning yarn has poor wear resistance because most of the fibers are in the form of spiral threads, and when repeatedly rubbed, the spiral thread fibers gradually become axial fibers, and the yarn is easy to lose twist and disintegrate and wear off quickly. Non-traditional spinning yarn has obvious advantages in abrasion resistance, rotor yarn, jet yarn and vortex yarn are composed of two parts: yarn core and outer fiber, the surface of the yarn wrapped with irregular twisted fiber, the yarn is not easy to disintegrate, while the surface friction coefficient of the yarn is large, in the fabric between the yarn and yarn hold well, not easy to produce relative slip, so the abrasion resistance improved. Compared with ring yarn, compact spinning yarn fiber arrangement is neat and straight, yarn structure is tight, fiber is not easy to disintegrate, so the yarn wear resistance is good.

3, from the fabric's organizational aspect: the fabric's organizational structure determines the tightness and thickness of the paper film, which has a significant impact on its abrasion resistance. Among the three basic tissues, the abrasion resistance of the plain tissue, the abrasion resistance of the satin tissue is zui poor, and the twill is in the middle.

4, from the fabric finishing method: fabric finishing is a combination of physical and chemical methods to give the fabric a specific performance finishing. Such as protective finishing: waterproof, fire, mildew, oil, cold, anti-atomic radiation \ anti-melting, anti-pilling, etc.. Resin finishing can significantly improve the abrasion resistance of the fabric.
