In the textile industry, the fabric treated by silica sol has high strength, the fabric size is stable, and the recovery elasticity is high, the invention improves the production efficiency and can spin the products with high count. In the process of wool spinning, silica sol is used as sizing agent in diameter spinning to reduce the breaking rate of wool fiber. Titanate fibers are included in the coating, and the silica sol can increase the surface heat resistance of the inorganic fiber material. The dosage of silica sol is generally controlled at 2-5% . You show into the state, that is, in wool and fine short hair, at the beginning of the addition, but the silica sol contains a certain amount of water, to calculate the machine in the moisture. Suppliers of silica sol s est adding silica sol to the sizing of diameter yarn to reduce end breakage and save size, and adding silica Sol to the polyvinyl alcohol, carboxymethyl cellulose, natural starch and grease and other slurry, can make diameter yarn separation easy, non-slip continuous yarn, woven nylon fishing net net net knot firm, not easy to slip loose; Nylon rope treated with silica sol can increase the friction between monofilaments, which can not only prevent slip, but also reduce its elongation, if the use of silica sol-treated fibers, you can get fluffy, elastic and no smooth feeling of bedding. The extinction effect can also be obtained by treating chemical fibers with silica sol
