The so-called High Tenacity Polyester Filament Twisted Yarn is a process of winding raw silk into yarn. For example, a yarn is composed of 24 filaments. The 24 filaments need to be intertwined to make the yarn more solid and delicate. The tighter the winding, that is, the higher the twist, the fabric will be relatively compact, with good sag and fastness. High tenacity polyester fiber twisted yarn is produced by twisting.

The application range of High Tenacity Polyester Filament Twisted Yarn is as follows; Viscose twist yarn, polyester twist yarn, nylon twist yarn, real silk twist yarn and other varieties, jinsiyuan special silk products with its latest development technology, non steam vacuum setting make its twist yarn quality superior, twist yarn is also known as double twist yarn, also known as twist yarn, in short, let its filament add twist.

High Tenacity Polyester Filament Twisted Yarn is a kind of twisted yarn. It is suitable for knitting and weaving, covering all fields of textile. The specification is thick yarn because the thickness (15D-50D is ultra-fine denier) is above 150D. The twist is measured by the number of twists per centimeter. It is said that 80-500 twists are weak twists, and 500-1000 twists are medium twists, More than 1000 twists are called strength twists. The direction of twist is s and Z. according to the fabric style, it is necessary to use single Z twist or s and Z pair,

High Tenacity Polyester Filament Twisted Yarn also needs specific machines and materials to make twisted yarn. It can be understood that double twist yarn must be produced by double twist machine. High Tenacity Polyester Filament Twisted Yarn can be made by twisting machine. It's just different in different specifications. But the super fine denier twisted yarn (double twisted yarn) must be made on the real silk double twisting machine with strong professional requirements. Relevant tension and path are the guarantee of quality process.
