Abstract

The invention provides a high-friction textile raw material and a preparation method thereof, wherein a high polymer material is doped with an inorganic nano material, so that the friction force of plastic is increased. The method comprises the following steps: (1) grinding a nano material and a high polymer material together by using a vibration mill; and (2) modifying an inorganic nano oxide on the surface of the high polymer material by using an atomic layer deposition technology, so that the surface of the high polymer material is rougher. The preparation method is simple, and the performance of the obtained product is obviously higher than that of existing market products.

Description

technical field [0001] The invention relates to the field of preparation of polymer materials, in particular to a preparation method of a surface-modified polymer material, which is used in the manufacture of textiles. Background technique [0002] Abrasion resistance of textiles refers to the ability of textiles to resist abrasion under repeated mechanical friction. The abrasion resistance of textiles has a direct impact on the use time and effect of the product. The wear phenomena of textiles under repeated mechanical friction mainly include damage, weight loss, color fading, and pilling. [0003] The method to improve the wear resistance of textiles is mainly the post-finishing method, which combines physical and chemical methods to endow the fabric with certain specific properties. Such as protective finishing: waterproof, fireproof, mildew-proof, oil-proof, cold-proof, atomic energy radiation-proof, melting-proof, pilling-proof, etc. Resin finishing can significantly...
