Chemical fiber grade titanium dioxide is designed to meet the specific requirements of the chemical fiber industry. This special form of titanium dioxide has an anatase crystal structure and exhibits excellent dispersion capabilities, making it the first choice for chemical fiber manufacturers. It has a high refractive index and, when incorporated into fibers, imparts luster, opacity and whiteness. Furthermore, its stabilizing nature ensures long-lasting color stability and resistance to harsh environments, making it an ideal additive in man-made fiber production. One of the main advantages of chemical fiber grade titanium dioxide is its ability to enhance the performance and appearance of textiles and nonwovens. Adding this special titanium dioxide during the manufacturing process can significantly improve the fiber's color strength, brightness and UV resistance. Not only does this produce an attractive and vibrant end product, it also extends the life of the fabric, making it highly durable and versatile. In addition, the superior durability and resistance of chemical fiber grade titanium dioxide make it an important component in the production of various textile products, including sportswear, swimwear, outdoor fabrics and home textiles. It is able to withstand sunlight exposure and harsh atmospheric conditions, ensuring that textile products remain alive and retain their original qualities for a long time. In addition to its aesthetic and performance-enhancing properties, fiber-grade titanium dioxide has exceptional antimicrobial and self-cleaning capabilities. When incorporated into the fibers, it actively eliminates harmful bacteria, reducing the risk of infection and bad odour. In addition, its self-cleaning properties allow it to break down organic matter on the surface of the fabric, thereby reducing the maintenance requirements of textile products. The application potential of chemical fiber grade titanium dioxide is not limited to the textile industry. It is also used in the production of paints, coatings and plastics. Its high opacity and whiteness make it an excellent additive in the production of white paints and coatings, providing excellent coverage and brightness. In the plastics industry, it acts as a UV stabilizer to prevent discoloration and degradation of plastic products caused by prolonged exposure to sunlight.
