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.
