Description

Technical Field

[0001] The utility model relates to the technical field of stretch yarn, and more specifically, to a wear-resistant polyester stretch yarn. Background Art

[0002] Polyester stretch yarn is a kind of deformed yarn of polyester chemical fiber, which can be divided into high-elastic yarn and low-elastic yarn. It uses polyester chips as raw materials and adopts high-speed spinning to make polyester pre-oriented yarn. Pre-oriented yarn is generally not used directly for weaving and must be post-processed before it can be used. The process of stretching is: using pre-oriented yarn as raw material, through stretching and deformation treatment, the pre-oriented yarn is transformed into a stretch-deformed yarn with relatively stable physical properties that can be directly used for weaving. The treated stretch yarn has good elastic expansion rate, but because the structural strength between the fiber monofilaments is not very good after twisting and stretching, when the stretch yarn is subjected to external force, the fiber monofilaments move relative to each other, and the friction between them easily leads to the reduction of the strength and wear resistance of the stretch yarn itself.

[0007] When using a wear-resistant polyester stretch yarn of the present technical solution, the strength of the polyester stretch yarn is improved by winding a plurality of polyester yarns and a filling layer on the surface of the central fiber, and the wear-resistant layer is spirally wound on the surface of the polyester yarn and the filling layer in a short distance, thereby improving the wear resistance of the polyester stretch yarn and improving its compacting effect at the same time, thereby preventing the polyester yarn and the filling layer from becoming loose.
