Background
High performance composite materials, which generally require high performance fiber fabrics as the reinforcing or skeletal material, often have a mesh structure, especially a knitted mesh fabric, in order to provide good adhesion between the substrate and the fabric for optimum reinforcement. And since the warp knit fabric has an improved tensile strength in both the longitudinal and transverse directions compared to the weft knit fabric, the warp knit fabric is used as a reinforcing or skeleton material for a high-performance composite material. For example, aramid warp knitted fabrics with a certain density are widely used in various fields such as pressure-resistant and temperature-resistant rubber hoses for power systems, fuel pipes for automobiles, heater pipes, power steering pipes, rubber hoses for engine cooling systems, and the like.
In the prior art, warp-knitted mesh fabric is a knitted product, basic units of tissues are loops, the knitting is realized by mutual interlocking of the loops, and by tissue design, the yarns in longitudinal rows are locally disconnected, and the loops are interrupted to form mesh structures with different sizes, different shapes and a certain rule in the transverse direction. Therefore, in the weaving process, the repeated bending degree of the yarn is large, the requirement on the bending (flexibility) resistant strength of the yarn is high, conventional fibers such as conventional cotton yarn, polyester (or nylon) filament and the like can be used, and the high-performance mesh fabric is made of a high-performance fiber material which is large in initial modulus and strong in rigidity, and can generate holes due to broken ends of warp yarns during weaving to influence the normal use of the fabric; meanwhile, the warp knitting mesh fabric yarn forms eyelets through stitch stitches, generally only can be woven by single yarn due to gram weight and equipment limitation, the yarn strength is limited (far lower than that of strands or filaments), meanwhile, in order to form relatively large eyelets and take the gram weight into consideration, the overlapping degree of local yarns is large, the surface density uniformity of the base fabric is poor, the strength uniformity of the composite material is also poor, the whole axial tensile strength of the high-performance fiber material cannot be fully exerted due to the stitch stitches, and the whole longitudinal and transverse tensile strengths of the base fabric are low.
Therefore, further solutions to the above-mentioned problems are needed.
