Product Description

Features

When nano-silica is used as a sizing additive, it is beneficial to enhance the adhesion of the sizing to the fiber and improve the sizing properties of pure cotton yarn and polyester-cotton yarn. The content of hydroxyl in yarn directly affects the improvement of sizing performance of nano-silica, and nano-silica has a better effect on the surface and mechanical properties of pure cotton yarn. This product is prepared by special process, nano silica has high activity, so that the binding ability with the yarn surface hydroxyl group has been greatly improved, more conducive to sizing, thus playing the role of nano silica in textile.

Application 

1. It is beneficial to enhance the adhesion of the slurry to the fiber, and there is strong or weak hydrogen bonding between the active hydroxyl group on the surface and the hydroxyl group on the starch and cotton fiber, which can effectively improve the sizing performance of pure cotton and polyester cotton yarn.

2, nano silica is more conducive to the sizing of cellulose fibers.

3, with the effect of enhancing and increasing wear and reducing hair.

4. The slurry film of nano-silica mixed slurry has abrasion resistance compared with that of pure starch slurry.

5, improve the integrity and penetration rate of the slurry film.
