Abstract
The invention belongs to the field of production of warp-knitted fabrics, and in particular relates to a method for producing a warp-knitted biaxial felted reinforced fabric. The method for producing the warp-knitted biaxial felted reinforced fabric comprises the steps of producing single weft cloth, drawing the single weft cloth into skewing weft cloth through a skewing weft knitting machine, and producing a biaxial felted warp-knitted fabric. The method has the advantages that the weft direction of the biaxial felted reinforced fabric knitted by the process is unlikely to extend to two sides; the structural stability of the biaxial felted reinforced fabric is improved; a special structural design requirement on a biaxial felted fabric caused by a customer is met; fabrics with different breadths can be produced; the warp-knitted biaxial felted reinforced fabric has the characteristics of low extension rate, high strength and high resin permeability.

Summary of the invention
The weaving method that the objective of the invention is to strengthen fabric for the two axial zone felts of above-mentioned middle routine can't be produced Stability Analysis of Structures, fabric that intensity is high, a kind of pair of axial zone felt proposed strengthens the production method of fabric, it can be by upper and lower two-layer single shaft to strengthening 45 ° of 60 ° of the angled +/-of fabric oblique pull or angle +/-, by the weaving method of warp plain stitch, its binding is woven into to the enhancing fabric.
Warp-knitted bi-axial band felt strengthens the production method of fabric, and it comprises that the step of manufacture order latitude cloth, Dan Weibu pull into the step of Oblique Weft Fabric and the step of producing two axial zone felt WARP-KNITTINGs by skew weft knitting machine,
One, the step of manufacture order latitude cloth, formed by the bundled yarn braiding that is positioned at 0 ° of direction by the weft layers of the spun yarn layer that is positioned at 0 ° of direction and 90 ° of directions; Bundled yarn is low elastic polyester filament, and binding yarn number number is 55.5-83.3dtex, and the spun yarn layer of 0 ° of direction is glass fiber spun yarn, and number number of glass fiber spun yarn is 136dtex to the maximum, and upper secret degree is 3.0-5.0M/cm, and the unit are grammes per square metre is 400-600g/m
2, machine rotational speed is 400-600r/min, bundled yarn adopts pillar stitch;
Two, Dan Weibu pulls into the step of Oblique Weft Fabric by skew weft knitting machine, the Dan Weibu that step 1 is produced is held in place on the roll unwinding device after the biaxial warp knitting machine machine, then pull into respectively two groups of Oblique Weft Fabric by skew weft knitting machine, wherein the weft yarn angle of one group of Oblique Weft Fabric be+60 ° or+45 ° of inclinations, another the group Oblique Weft Fabric weft yarn angle be-60 ° or-45 ° of inclinations;
Three, the step of two axial zone felt WARP-KNITTINGs, two axial zone felt WARP-KNITTINGs be by being+60 ° or+45 ° of Oblique Weft Fabric that direction tilts, the Oblique Weft Fabric that is-60 ° or-45 ° direction inclinations forms the first layer, the second layer, lay in addition the chopped layer of 0 ° of direction, chopped layer forms the 3rd layer, by the first layer, the second layer, total bundled yarn integrated by weaving for the 3rd layer, wherein bundled yarn is positioned at 0 ° of direction, the 3rd layer is positioned at the first layer, the upper strata of the second layer, the weft yarn of Oblique Weft Fabric is woven glass roving fabric, latitude yarn number number is below 2400tex, the first layer, the upper secret degree of the second layer is 2.0～3.0M/cm, the unit are grammes per square metre is: 900～1500g/ ㎡, machine rotational speed is 300～500r/min, total bundled yarn adopts warp plain stitch.
What in described step 1, step 3, adopt is biaxial warp knitting machine, and the step 1 plane No. is E10; The step 3 plane No. is E7.
Advantage of the present invention is that two axial zone felts of this craft woven strengthen fabric, broadwise is difficult for expanding and prolonging to both sides, improved the structural stability that two axial zone felts strengthen fabric, met the specific (special) requirements of client to two axial zone felt fabric textures, and can produce different fabric widths, fabric has the advantages that percentage elongation is little, intensity is high, resin impregnated is good.
