High-strength polyester Bondi thread is an industrial long-fiber polyester sewing thread with relatively good breakage resistance and wear resistance, and it has excellent acid resistance and UV resistance. High-strength polyester Bondi yarn is made by twisting and bonding three or four polyester filaments together, making the yarn more uniform and enhancing its wear resistance, thereby improving its sewability. It is widely used as sewing thread for high-quality leather goods products.

High-strength polyester Bondi thread is our factory's flagship product. Our unique seamless and advanced oiling process ensures that the products have excellent gloss and lubricity, guaranteeing that each product has superior sewability. Composition: Polyester long fiber Dyes for dyeing: Disperse dyes Coloring temperature: 130℃
