Application of silica sol in textiles In the textile industry, fabrics treated with silica sol have high strength, stable fabric dimensions, and high recovery elasticity; silica sol and synthetic wool oil are used together to increase the cohesion between fibers and increase the tensile strength. , improves production efficiency and can spin high-count products. During the wool spinning process, silica sol is used as an auxiliary for spinning sizing to reduce the breakage rate of wool fibers. Titanate fiber and silica sol are included in the coating to increase the surface heat resistance strength of the inorganic fiber material. The dosage of silica sol is generally controlled at 2 to 5%. The best adding state is when wool and fine short hair are first added, but the silica sol contains a certain amount of moisture, which must be calculated into the moisture regain on the machine. Adding silica sol to the diameter yarn sizing can reduce breakage and save sizing; when using fine-grain rolling or twisting sizing, add silica sol to polyvinyl alcohol, carboxymethyl cellulose, natural starch, oil and other materials In the slurry, the radial yarns can be separated easily, and the yarns are anti-slip and continuous. The woven nylon fishing net has a strong knot and is not easy to slide and loosen; the nylon rope treated with silica sol can increase the friction between the single filaments. It is anti-slip and can reduce its elongation; bedding materials made of synthetic fibers are generally smoother. If you use fibers treated with silica sol, you can get a bedding that is fluffy, elastic and non-slippery. Treating chemical fibers with silica sol can also obtain a matting effect. Silica sol can also be used in fabric dyeing. Because it has adhesive properties and can form an excellent protective liquid, it helps the pigment adhere to the surface of the fabric, increases the uniformity and fastness of dyeing, and prevents pigment aggregation; add silica sol with 60% of the pigment amount to the starch glue. Used to treat fabrics, such as carpets, etc. After treatment, they can be anti-slip, dust-proof, prevent static electricity, and do not stick to dust. Nylon yarn is dipped in 5% silica sol solution and knitted into socks, which can prevent or reduce the generation of burrs. In short, the range of fabrics that can be treated with silica sol is extremely wide. Regardless of various textiles and knitwear, as well as fabrics made of nylon viscose fiber, polyester, acetate fiber, polypropylene, etc., it can be treated with good results.
