With the development of the Times the wide use of high-speed sewing machines makes the application range of core sewing thread expanding. But what are the benefits of a high-speed sewing machine with a core sewing thread? The following benefits are specifically described here:
Core sewing thread is mainly used in high-speed sewing, due to the friction between stitches and fabrics, the temperature of the stitches will rise sharply, especially the speed in 5000/min above, sewing needles will be more than 300 degrees, and high-strength polyester filament of the melting point of 255 degrees to 260 degrees, so the polyester filament thread easy to fuse. The use of core sewing thread can avoid the above problems, because the core sewing thread to filament as the core, the outsourcing of cotton polyester staple fiber or high-quality cotton. Therefore, polyester filament is not directly contact with needle needle, and surface fiber can quickly dissipate heat.
