1. High Tenacity Polyester Filament Sewing Thread: It is made of 65% polyester and 35% cotton. It has the advantages of polyester and cotton. It has high strength, wear resistance, heat resistance and good shrinkage. It is mainly used for cotton, High-speed sewing of various garments such as polyester and cotton.

2. High Tenacity Polyester Filament Hollow Sewing Thread: The filament is the core and is made of natural fiber outsourcing. The strength depends on the core thread. The wear resistance and heat resistance depend on the outer yarn. It is mainly used for high-speed and firm garment sewing.

In recent years, with the further improvement of labor production efficiency and the widespread use of high-speed sewing machines, the application range of High Tenacity Polyester Filament Hollow Sewing Thread has been continuously expanded. The reason is that due to the friction between the needle and the fabric during high-speed sewing, a large amount of heat is generated on the needle; when the number of fabric layers to be sewn increases (such as shirt collars, etc.), the temperature of the needle will rise sharply, especially when sewing When the speed is above 5000 stitches/min, the stitches will exceed 300℃, and the melting point of High Tenacity Polyester Filament Sewing Thread is 255℃-260℃, so the polyester filament thread is easy to break.

Using High Tenacity Polyester Filament Hollow Sewing Thread can avoid the above problems, because the polyester filament in High Tenacity Polyester Filament Hollow Sewing Thread does not directly contact the needle eye, and the surface fiber can quickly dissipate heat. High-strength polyester and cotton core-spun sewing threads are made of high-strength polyester filaments outsourcing cotton-type polyester staple fibers or high-quality long-staple cotton.

High Tenacity Polyester Filament Hollow Sewing Thread not only has the high strength of polyester filament sewing thread, but also has the natural hairiness and feel of polyester staple fiber sewing thread or upper thread. It is very suitable for high-speed sewing and can fully meet the style of clothing fabrics and other technologies. The requirements for the use of wires in the field have broad prospects for development.
