Abstract

The invention relates to semidull POY polyester fiber and a processing method thereof. The method specifically includes the steps that melt is online added into a front-of-pump injecting system through direct spinning, prepared semidull polyester slices serve as the front-of-pump injecting raw material, conventional polyester melt serves as main melt, and the semidull polyester melt and the main melt are mixed through the front-of-pump injecting system, are then subjected to before-spinning filtering, enter a spinning assembly to be subjected to melting and spinning, and are subjected to annular air blowing cooling, oiling, stretching and rolling to obtain the semidull POY polyester fiber. The semidull POY polyester fiber has excellent delustering effect, and the polyester POY fiber prepared with low addition content of titanium dioxide is high in tensile strength, high in inorganic powder dispersity and good in delusteirng effect, and has the advantages of preventing see-through, being high in luster and the like when used for preparing clothes fabric and home textile fabric.

Description

technical field [0001] The invention relates to the technical field of textile production, in particular to a semi-dull POY polyester fiber and a processing method thereof. Background technique [0002] Due to its excellent mechanical properties and heat resistance, polyester fiber has a very wide range of applications in clothing, home textiles, industrial use and other fields; as a high-end clothing fabric, polyester filaments are required due to their excellent light transmission The matting treatment of its light transmission has achieved the effect of shading and luminescence, making the fabric opaque or reducing its light transmission; titanium dioxide is a commonly used matting agent for polyester filaments, and it is usually beaten by copolymerization at present. The process of adding titanium dioxide as a matting agent for copolymerization to prepare a matting titanium dioxide product; POY polyester filament itself has a highly oriented structure, due to its re-draw...
