Method for weaving coating terylene industrial yarn doup structure sunshade screen

Abstract

The invention discloses a method for weaving a coating terylene industrial yarn doup structure sunshade screen. the invention adopts coating terylene industrial yarn as raw materials of warp yarn and weft yarn and comprises the following steps: carrying out warping and drawing-in on the warp yarn and then weaving together with the weft yarn; inspecting blanks, stretching or hot-rolling baking and moulding to obtain a finished product. The method is characterized in that the warp yarn is divided into a ground warp and a doup warp according to a texture structure, and the doup warp and the ground warp are arranged according to a certain proportion; by adopting a doup device, the doup warp generates left and right doup rotation around the ground warp in the weaving process to be interwoven into a leno texture pattern weaving grain mesh structure together with the weft yarn; and by utilizing the characteristic that a gel melting point of a surface coating of composite yarn is lower than that of core-layer terylene yarn, after fabrics are woven, the stretching baking or the hot-rolling moulding is carried out to form an even and stable mesh-shaped fabric structure. The coating terylene yarn doup structure sunshade screen material has the characteristics of high strength, excellent toughness, corrosion resistance and aging resistance.

Description

technical field [0001] The invention relates to a method for weaving a sunshade net with a coated polyester industrial yarn skein structure. Background technique [0002] The sunshade net is a flexible material that uses mesh fabric to block strong sunlight and is used to adjust the light intensity of living rooms, halls or outdoor parking lots, greenhouses, green belts and other places. Among them, the medium and low-grade sunshade nets are made of polypropylene split film flat wire woven nets processed by asphalt coating. The net structure is loose, high porosity, high light transmittance and low wind resistance. It is mainly used in outdoor parking lots and greenhouses. , green belts, newly planted large trees to keep alive or field planting and other places to adjust the intensity of light in hot summer, prevent sun exposure, prevent heavy rain, reduce wind speed, adjust humidity, prevent insects and birds, etc., in urban greening, dairy farming, greenhouse planting, Gr...

AI Technical Summary

Problems solved by technology

[0003] Because the medium and low-grade sunshade nets are made of asphalt-coated polypropylene split film flat wire mesh, the material has poor sun resistance and mesh stability, low strength, easy aging, single color, rough structure, and no decoration.

Although the high-grade fabric-coated sunshade net has stable structure, high strength, anti-aging and certain decorative effects, this kind of sunshade net requires a relatively tight fabric structure, a large amount of coating, too low porosity, fine and rigid voids, and lack of three-dimensional structure. effect and artistic effect, therefore, it cannot meet the light transmission and decoration style requirements of high-end luxury environment
