When nano-silica is used as a sizing additive, it is beneficial to enhance the adhesion of the slurry to the fiber, and can effectively improve the sizing performance of pure cotton yarn and polyester-cotton yarn. The content of hydroxyl groups in the yarn directly affects the effect of nano-silica on sizing. In terms of performance improvement, nano-silica has a better effect on improving the surface properties and mechanical properties of pure cotton yarn sizing. This product is prepared through a special process. Nano-silica has high activity, which greatly improves the binding ability with hydroxyl groups on the yarn surface, which is more conducive to sizing, thus giving greater advantage to nano-silica in textiles. function on.

Application characteristics of textile-specific nanosilica:
. It is beneficial to enhance the adhesion of slurry to fibers, and the active hydroxyl groups and starch on its surface and cotton fiber There are strong or weak hydrogen bonds between the hydroxyl groups on the yarn, which can effectively improve the sizing properties of pure cotton and polyester-cotton yarns.
. Nano-silica is more conducive to the sizing of cellulose fibers.
.It has the effect of enhancing and increasing grinding and reducing hairiness.
.The size film of the mixed slurry of nano-silica has better wear resistance than the size film of pure starch slurry.
