Detailed Description
The present invention will be further described with reference to the accompanying drawings and specific embodiments.
The first embodiment is as follows:
a tear resistant high strength warp knit fabric comprising: a base fabric layer 1; the base cloth layer 1 adopts a full width weft insertion warp knitting structure, the main body is formed by warp knitting high-strength environment-friendly yarns, and ultrahigh molecular weight polyethylene fiber yarns are inserted;
the high-strength environment-friendly yarn comprises a core yarn and a cladding yarn, wherein the core yarn is formed by cabling three strands of regenerated polyester filaments 11; the wrapping yarn is a regenerated nylon yarn 12, and the regenerated nylon yarn is spirally wound outside the core yarn. At least one of the three strands of regenerated polyester filament yarns is antibacterial regenerated polyester filament yarn, so that the high-strength environment-friendly yarn has antibacterial property, the functions of warp knitted cloth are enriched, and the texture of all over warp yarns is improved.
Preferably, the preparation method of the antibacterial regenerated polyester filament comprises the following steps: step 1, pre-crystallizing materials, wherein the materials belong to PET bottle piece recycled materials; specifically, the method comprises the steps of pre-crystallizing by dehumidifying and drying hot air; step 2, feeding materials in a screw type; feeding the dried PET bottle flakes into a screw extruder; step 3, filtering, homopolymerizing and pressurizing; filtering the melt extruded by the extruder, then adding the filtered melt into a homopolymerization reaction kettle for tackifying, vacuumizing to remove small molecules, simultaneously mixing polyester macromolecular chain segments uniformly, and then using a booster pump to ensure the continuous production of spinning and the constancy of melt pressure; and 4, adopting a set of homopolymerization reaction kettle by the composite spinning technology, preparing the melt of the skin layer core layer from the reaction kettle, additionally arranging a dynamic mixer on a melt pipeline of the skin layer, controlling the quantitative injection of the antibacterial master batch melt by a computer, injecting the two groups of melts into the composite spinning assembly through the melt pipeline for spinning, wherein the melts with the antibacterial effect are of a skin layer structure, the conventional melts are core layers, and then winding and forming are carried out.
