Embodiment 1

[0027] A thread coating method for PVC-coated polyester industrial yarn, using polyester industrial yarn and PVC coating adhesive as raw materials, using polyester industrial yarn as the core material, using PVC coating adhesive as the cortex material, and coating the polyester industrial yarn The tows are composited into monofilaments of skin-core structure. The specific process is that the polyester industrial yarn is dipped in PVC coating glue to hang the glue to make the silk thread glued. After the silk thread is glued, it is extruded and scraped, and then spirally wound on the infrared baking cylinder with a diameter of 300mm at a distance of 15mm. Baking, the baking temperature is 190°C, after the dried silk thread is cooled by blowing and coiled, the coating glue is deeply infiltrated and coated on the core layer polyester industrial thread to form a composite structure coated thread.

Embodiment 2

[0033] A thread coating method for PU-coated polyester industrial yarn, which uses polyester industrial yarn and PU coating adhesive as raw materials, adopts polyester industrial yarn as the core material, adopts PU coating adhesive as the cortex material, and adds Nanoscale ZiO 2 Anti-ultraviolet and anti-aging agent, phosphorus flame retardant and ecological safety insect repellent, the polyester industrial tow is compounded into a skin-core structure monofilament after coating. The specific process is, first, the nano-sized ZiO 2 Anti-ultraviolet and anti-aging agents, phosphorus flame retardants, ecological safety insect repellents, etc. are uniformly dispersed and added to the PU coating adhesive in a certain proportion and mixed to form a PU functional coating adhesive, and then the polyester industrial yarn is added to the PU functional coating adhesive. The coating glue is soaked in hanging glue to make the silk thread glued. After the silk thread is glued, it is extr...

Embodiment 3

[0039] A thread coating method for PE-coated polyester industrial yarn, using polyester industrial yarn and PE coating adhesive as raw materials, using polyester industrial yarn as the core material, using PE coating adhesive as the cortex material, and adding Phosphorus-based flame retardant is added, and the polyester industrial tow is compounded into a skin-core structure monofilament after coating. The specific process is that first, the phosphorus-based flame retardant is uniformly dispersed and added to the PE coating glue in a certain proportion and mixed to form a PE functional coating glue, and then the polyester industrial yarn is impregnated with the glue in the PE coating glue. Apply glue to the silk thread, squeeze and scrape the glue after the thread is glued, and then wind it spirally on an infrared baking cylinder with a diameter of 350mm at a distance of 25mm for baking. The baking temperature is 200°C, and the dried silk thread is then blown After cooling and...

Abstract

The invention discloses a silk-coating method for PVC/PU coating polyester industrial yarns and a device thereof. The method comprises the following steps: using polyester industrial yarns as raw materials and a core layer structure; adopting a PVC-coating adhesive as a surface structure; dipping the polyester industrial yarns in the PVC-coating adhesive so that the adhesive is stuck to the silk;extruding the silk; scraping the adhesive; then, winding the silk in a spiral shape and baking; and drying, cooling the dried silk by cold air and coiling so that the coating adhesive is deeply permeated and coated on the core layer structure to form the silk of the coating polyester industrial yarns. The composite silk material has the advantages of high strength, good toughness, corrosion resistance, aging resistance, and the like. A melting point of PVC, PU or PE coating adhesive on the surface is lower than that of core-layer polyester yarns, woven fabrics in a stretching state are baked at high temperature or thermally rolled, shaped and processed, and warp yarns and weft yarns are melted and fused by the coating adhesive so that mesh fabrics are integrally smooth and stiff and meshesare uniform and stable.

Description

technical field [0001] The invention relates to a thread coating method and equipment for PVC / PU coated polyester industrial threads. 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 characteristics of high strength, low elongation, high modulus, and high dry heat ...
