High strength and low shrinkage colored polyester filament

     High strength and low shrinkage colored polyester filament is a synthetic fiber with special properties, mainly made of polyester as the main raw material. Through a specific spinning process, colored masterbatch is added to the production process for coloring, so that the fiber presents various colors while having high strength and low shrinkage properties, without the need for subsequent dyeing processing, reducing environmental pollution and production costs.
