Abstract

The application relates to the technical field of polyester fibers, and specifically discloses a high wear-resistant POY polyester yarn and a preparation method thereof. The preparation method includes the following steps: S1: raw material preparation; S2: melt extrusion: melt extrude the raw material, and filter; S3: spinning: obtain POY precursor; S4: cooling, clustering and oiling: cooling POY precursor, Bundled and oiled with an oil agent; S5: winding molding; raw materials include the following components in parts by weight: 100 parts of polyethylene terephthalate; 2-9 parts of self-drying silicone resin; the oil The agent comprises the following components in parts by weight: 40-60 parts of smoothing agent; 20-40 parts of emulsifier; 3-7 parts of antistatic agent; 0.5-2 parts of sizing agent. The POY polyester yarn obtained by the preparation method of the present application has the advantage of lower friction coefficient, thereby improving wear resistance.

Description

technical field [0001] This application relates to the technical field of polyester fibers, more specifically, it relates to a high wear-resistant POY polyester yarn and a preparation method thereof. Background technique [0002] POY is a pre-oriented filament, which is an incompletely stretched chemical fiber filament obtained by high-speed spinning with a degree of orientation between the unoriented filament and the drawn filament, based on polyethylene terephthalate (PET). . POY has a certain degree of orientation and good stability, and is generally used to draw false twist textured yarn (DTY). [0003] Since POY needs to be stretched and deformed at a high temperature of 200-220°C during the process of processing to DTY, and at the same time be subjected to high-speed shearing action of false twist friction disc, it will be subject to great friction. Therefore, the wear resistance of POY will directly affect whether the processing of DTY can be carried out smoothly. ...
