Nano-silica,
slurry additive, is beneficial to enhance the adhesion of slurry to fiber, and
can effectively improve the sizing performance of pure cotton yarn and
polyester-cotton yarn; the content of hydroxyl in yarn directly affects the
performance of nano-silica on sizing The degree of improvement, nano-silica has
a better effect on the surface properties and mechanical properties of pure
cotton yarn sizing. The product is prepared by a special process, and the nano
silica has high activity, so that the binding ability with the hydroxyl surface
of the yarn is greatly improved, and the sizing is more favorable, thereby
exerting a greater advantage in the nano silica in the textile. The role of the
above.

Application
characteristics of textile-specific nano-silica:
1.
It is beneficial to enhance the adhesion of the slurry to the fiber. There is a
strong or weak hydrogen bond 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 sizing of cellulose fibers.
3.
with the effect of strengthening and grinding and reducing hairiness.
4.
The slurry film of the mixed slurry of nano silica has better wear resistance
than the slurry film of pure starch slurry.
