Polyester Semi Dull Chip is a widely used raw material in the textile industry, specifically for producing fibers, filaments, and various packaging materials. These chips have a matte appearance due to the addition of titanium dioxide (TiO2) during the polymerization process, which diffuses light and reduces the sheen on the final product. Known for their excellent tensile strength, durability, and chemical resistance, Semi Dull Chips are ideal for creating fabrics that require a less glossy finish, such as clothing, upholstery, and industrial textiles. Their versatility also extends to applications in the film and bottling industries.

Semi Dull Chip is commonly used in the production of polyester fibers and yarns, which are then utilized in a wide range of applications. In the textile industry, these fibers are used to manufacture fabrics for clothing, including sportswear, casual wear, and formal attire. In home furnishings, they are used in the production of items such as curtains, upholstery, and bed linens. Additionally, Semi Dull Chips find applications in industrial sectors, where they are used to produce high-strength ropes, conveyor belts, and filtration materials. Their versatility and durability make them a preferred choice across various industries.
Matte Finish: Polyester Semi Dull Chips feature a reduced gloss finish due to the addition of titanium dioxide (TiO2), making them ideal for fabrics with a more subdued appearance.
High Durability: These chips offer strong resistance to chemicals, abrasion, and moisture, making them suitable for textiles requiring long-lasting performance.
Versatile Applications: They are commonly used in the production of fibers, filaments, and industrial materials like upholstery and packaging, due to their balanced strength and flexibility.
Environmentally Friendly: Polyester Semi Dull Chips are recyclable, which aligns with sustainability initiatives in textile and packaging industries.
