Product Details

Product Introduction

When used as a slurry additive, this product helps enhance the slurry's adhesion to fibers, effectively improving the sizing performance of pure cotton and polyester-cotton yarns; the hydroxyl content in the yarn directly affects the degree to which nano-silicon dioxide improves sizing performance, and nano-silicon dioxide shows a better improvement effect on the surface and mechanical properties of pure cotton yarn sizing. This product is prepared through a special process, and the nano-silicon dioxide has high activity, which greatly improves its ability to combine with the hydroxyl groups on the yarn surface, making sizing easier and further enhancing the advantages of nano-silicon dioxide in textiles.

Application Range

1. It helps enhance the adhesion of the slurry to the fibers; the active hydroxyl groups on its surface and the hydroxyl groups on starch and cotton fibers have hydrogen bonding, which can effectively improve the sizing performance of pure cotton and polyester-cotton yarns;

2. It is more conducive to sizing cellulose fibers;

3. It has the effect of strengthening, increasing gloss, and reducing fuzz;

4. The sizing film of the composite slurry with starch has better wear resistance than the sizing film of pure starch slurry;

5. The composite slurry with starch can replace or partially replace PVA slurry and is a green and environmentally friendly material.
