JapanWith the wide use of high-speed sewing machines, the application range of core-spun sewing threads has been continuously expanded. But what are the benefits of core-spun thread for high-speed sewing machines? Yiyang clothing equipment to introduce to you.
1. Core-spun sewing thread is mainly used in high-speed sewing. Due to the friction between the needle and the fabric, the temperature of the needle will rise sharply, especially when the speed is above 5000/min, the needle will exceed 300 degrees, and high-strength polyester The melting point of the filament is 255 degrees to 260 degrees, so the polyester filament thread is easy to melt.
2. The core-spun sewing thread has the high strength of polyester filament sewing thread, and has the natural hairiness and feel of polyester staple sewing thread or cotton thread, which is very suitable for high-speed sewing.
3. Because the core-spun sewing thread uses filament as the core and is covered with cotton-type polyester staple fiber or high-quality long-staple cotton. Therefore, the polyester filament does not come into direct contact with the needle eye, and the surface fibers can quickly dissipate heat.
Cotton-covered polyester is mainly suitable for upholstered furniture, automotive industry, light fabrics and decorative sewing of leather and denim. Polyester packaged polyester is mainly suitable for high-quality products such as shoe materials, tablecloths, bedding, and sportswear, coats, and security clothing.
