High strength and low shrinkage polyester three leaf shaped filament

     High strength and low shrinkage polyester three leaf shaped filament is a synthetic fiber with special properties and morphology, mainly composed of polyethylene terephthalate (PET), which is made by condensation reaction of terephthalic acid (PTA) and ethylene glycol (EG). During the production process, some special additives may be added to improve the performance of fibers, such as increasing strength and reducing shrinkage. Fibers have high tensile strength, higher than ordinary polyester filament, can withstand greater tensile forces, and are not easily broken. The cross-section of the fiber is in a trilobite shape, which endows the fiber with some unique properties.
