Embodiment 1

[0029] (1) Colored and flame-retardant masterbatches are compounded with colored additives and flame-retardant additives;

[0030] (2) Add colored flame retardant masterbatch through flexible online adding device;

[0031] (3) Drying of colored flame retardant masterbatch: dry air dew point ≤ -50, wind pressure 1.2kgf, temperature 90°C, drying time 8 hours, water content of masterbatch ≤50ppm;

[0032] (4) Compounding of colored flame retardant masterbatch and high-viscosity slices: the colored flame-retardant masterbatch is accurately supplied quantitatively by a metering station of the metering device, and at the same time, the high-viscosity slices with a viscosity of 1.08dL / g Through horizontal conveying, it enters another metering station for metering, and at the same time enters the static mixing unit to obtain the multifunctional composite masterbatch and high-viscosity chip compound mixture according to the required process requirements, and send it to the batching bin...

Embodiment 2

[0047] (1) Colored additives, flame retardant functional additives and anti-ultraviolet aging additives are compounded to make colored flame-retardant and anti-aging masterbatches;

[0048] (2) Add colored flame retardant and anti-aging masterbatch through flexible online adding device;

[0049] (3) Drying of colored flame retardant and anti-aging masterbatch: dry air dew point ≤ -50, wind pressure 1.3kgf, temperature 95°C, drying time 9 hours, water content of masterbatch ≤55ppm;

Abstract

The invention relates to a production method for flexible preparation of a high-strength polyester industrial yarn with multiple composite functions. One or more functional master batches are added through a flexible online adding device; the coloring of an original solution is taken as the basic function to prepare the high-strength polyester industrial yarn with multiple composite functions, ortwo or more functional additives are compounded into composite functional master batches; and then the composite functional master batches are added by using the flexible online adding device to prepare the corresponding high-strength polyester industrial yarn with multiple composite functions. The production method provided by the invention is continuous and stable in production, can be used forproducing matching products according to the different needs of subsequent customers, effectively improves the efficiency and lowers the labor cost; and the products obtained by production have more than two (including) functional characteristics.

Description

technical field [0001] The invention belongs to the technical field of textiles, and in particular relates to a production method of high-strength polyester industrial yarn with multiple composite functions. Background technique [0002] Polyester industrial yarn refers to high-strength, coarse denier polyester industrial filament, and its fineness is generally 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 characte...
