Abstract

The invention discloses a production method for colored PET industrial filaments. A chip spinning one-step method production line is employed; when PET melt flux passes through a melt flux pipeline, color oil and auxiliary agent are added to the PET melt flux via an injection port on the melt flux pipeline; then the color oil and the PET melt flux are evenly mixed via a plurality of novel static mixers in the melt flux pipeline; and the mixed PET melt flux is redistributed into a spinning case or each spinning position. Colored high-strength PET industrial filament possesses even and bright colors, requires short production period and low energy consumption by the use of the production method.

Description

technical field [0001] The invention belongs to the technical field of textiles, and in particular relates to a production method of colored polyester industrial yarn. Background technique [0002] Polyester industrial yarn refers to high-strength, coarse-denier polyester industrial filament, and its fineness is not less than 550dtex. According to its performance, it can be divided into high strength and low elongation type (ordinary standard type), high modulus and low shrinkage type, high strength and low shrinkage type, and active type. Among them, high-modulus low-shrinkage polyester industrial yarn has a tendency to gradually replace ordinary standard polyester industrial yarn in tires and mechanical rubber products due to its excellent properties such as high breaking strength, high elastic modulus, low elongation, and good impact resistance. ; High-strength and low-elongation polyester industrial yarn has the characteristics of high strength, low elongation, high mod...
