When using nano silica as a sizing additive, it is beneficial to enhance the adhesion of the slurry to fibers, and can effectively improve the sizing performance of pure cotton and polyester cotton yarns; The content of hydroxyl groups in yarn directly affects the degree of improvement of sizing performance by nano silica, and nano silica has a better effect on the surface and mechanical properties of pure cotton sizing. This product has been prepared through a special process, and nano silica has high activity. This greatly improves the binding ability with hydroxyl groups on the surface of the yarn, making it more conducive to sizing and thus giving greater advantages to the role of nano silica in textiles.

Application characteristics of textile specific nano silica:

1. Beneficial for enhancing the adhesion of the slurry to fibers, there are strong or weak hydrogen bonding interactions between the active hydroxyl groups on its surface and the hydroxyl groups on starch and cotton fibers, 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. It has the effect of enhancing and increasing wear, as well as reducing hairiness.

4. The slurry film of nano silica mixed slurry has better wear resistance than that of pure starch slurry.
