Warp-knitting-like high-performance woven mesh fabric and weaving method thereof

Abstract

The invention provides a warp-knitting-like high-performance woven mesh fabric and a weaving method thereof, and relates to the technical field of weaving. The warp-knitting-like high-performance woven mesh fabric comprises a plurality of warp units arranged side by side, each warp unit comprises two pieces of warp, the two pieces of warp are twisted together to form the warp unit, and a plurality of through holes are continuously formed in the length direction of the warp units; the plurality of wefts are arranged side by side in the length direction of the warp units, and the wefts sequentially penetrate through one through hole of each warp unit to connect the plurality of warp units; wherein every two adjacent warp units and every two adjacent weft units are enclosed to form meshes. According to the structure provided by the warp-knitting-like high-performance woven mesh fabric, high-performance fibers can be used for weaving in a weaving mode, the problems of broken holes and curled edges generated by the high-performance fiber woven mesh fabric are solved, meanwhile, the tensile strength is improved, and the gram weight of the fabric is reduced.

Description

technical field [0001] The present application relates to the technical field of weaving, in particular to a warp-like high-performance woven mesh fabric and a weaving method thereof. Background technique [0002] High-performance composite materials usually require high-performance fiber fabrics as reinforcement or skeleton materials. In order to have good adhesion between the substrate and the fabric to achieve the best reinforcement effect, the fabric is often used in a mesh structure, especially Knitted mesh fabric. And because the longitudinal and transverse tensile strength of warp knitted fabrics are improved compared to weft knitted fabrics, warp knitted fabrics are used as reinforcement or skeleton material of high-performance conforming materials. For example, aramid warp knitted fabrics with a certain density are widely used in various fields such as power system pressure and temperature resistant hoses, automobile fuel pipes, heater pipes, power steering pipes, ...

AI Technical Summary

Problems solved by technology

For this reason, in the weaving process, the repeated bending degree of the yarn is relatively large, and there is a high requirement for the bending resistance (flexibility) strength of the yarn. Conventional cotton yarn, polyester (or nylon) filament and other conventional fibers can be used. The high-performance mesh fabric uses a high-performance fiber material with a large initial modulus and strong rigidity. When weaving, holes will be generated due to warp yarn breakage, which will affect the normal use of the fabric; To form holes, due to the limitation of gram weight and equipment, generally only single yarn can be used for weaving, and the yarn strength is limited (far lower than strands or filaments). At the same time, in order to form relatively large holes and take into account the gram weight, the local yarn The degree of overlap is large, the surface density uniformity of the base fabric is poor, and the strength uniformity of the composite material is also poor. The knitted loop structure cannot give full play to the overall axial tensile strength of the high-performance fiber material, and the overall longitudinal and transverse tensile strength of the base fabric. low pull strength
