Abstract

The invention discloses a preparation method of a stain-resistant polyester industrial filament. The method comprises operation steps as follows: (1) polyurethane slices are put in a continuous solidphase polymerization device, melamine cyanurate and poly(cyclic amide) are added, the mixture is mixed uniformly and then subjected to a reaction at 235-240 DEG C for 20-25 h, and a base material is prepared; (2) the base material and an additive are mixed in the mass ratio being (18-22):1 and then added to a screw extruder, melt extrusion and traction drawing are performed, and the polyester industrial filament is prepared. The polyester industrial filament prepared with the provided preparation method of the stain-resistant industrial polyester filament has excellent mechanical properties and particularly has excellent stain resistance, and the quality of the polyester industrial filament is effectively improved.

Description

technical field [0001] The invention belongs to the technical field of polyester industrial yarn preparation, and in particular relates to a method for preparing stain-resistant polyester industrial yarn. Background technique [0002] Polyester industrial yarn has the advantages of high strength, large modulus, small elongation, good heat resistance, impact resistance, and good fatigue resistance.
