2016-07-27

With the development of the times, the wide use of high-speed sewing machine makes the application scope of core covered sewing thread expand. But what are the advantages of high-speed sewing machine with cored sewing thread? Here are the benefits:

The core covered sewing thread is mainly used in high-speed sewing. Due to the friction between the sewing needle and the fabric, the temperature of the sewing needle will rise sharply, especially when the speed is more than 5000 / min, the sewing needle will exceed 300 degrees, and the melting point of the high-strength polyester filament is 255 to 260 degrees, so the polyester filament is easy to fuse. The above problems can be avoided by using the core covering sewing thread, because the core covering sewing thread takes the filament as the core and is covered with cotton type polyester staple fiber or high-quality long staple cotton. Therefore, polyester filament does not contact with the needle eye directly, and the surface fiber can quickly dissipate heat. The core covering sewing thread has the high strength of polyester filament sewing thread, the natural hairiness and hand feeling of polyester staple sewing thread or cotton thread, which is very suitable for high-speed sewing. Cotton bag polyester is mainly used in upholstered furniture, automobile industry, light and thin fabrics, leather and denim decorative sewing. Polyester Bag polyester is mainly used for shoes, tablecloth, bedding, sportswear, overcoat, security clothing and other high-quality products. Changshu sewing equipment
