Abstract
The invention belongs to the field of methods for knitting warp-knitted fabrics and in particular relates to a method for knitting a warp-knitted biaxial reinforced fabric. The method comprises the following steps: laying reinforced fibers in directions of 0 degree and 90 degrees, feeding the reinforced fibers in the directions of 0 degree and 90 degrees into a knitting mechanism of a biaxial warp-knitting machine, binding, and knitting the reinforced fibers into the biaxial reinforced fabric. The method has the advantages that the biaxial reinforced fabric produced by the method is not easily ravelled in a warp direction when being cut, the structural stability of a uniaxial reinforced fabric is improved, the requirements of customers on avoidance of the ravelling of the warp yarns of the biaxial fabric in a cutting process are met, the product quality of the biaxial reinforced fabric is greatly improved, and the fabric has the characteristics of low elongation rate, high strength, good toughness and the like.
Description
Technical field
The invention belongs to WARP-KNITTING weaving method field, specifically a kind of warp-knitted bi-axial strengthens the weaving method of fabric.
Background technology
Conventional braiding twin shaft is by the laying of the laying by 0 ° of orientation enhancement fiber, 90 ° of orientation enhancement fibers to the method that strengthens fabric, by through flat or variation, through flat weaving method, its binding being woven into to the enhancing fabric.The twin shaft that adopts conventional method to weave out is to strengthening fabric when the cutting, and warp yarn is easily decoherenced, and structural stability is poor, can't meet the specific (special) requirements of client to Research in Fabric Shear.
Summary of the invention
The characteristics that while the objective of the invention is can't avoid cutting for above-mentioned middle conventional twin shaft to the weaving method that strengthens fabric, fabric is decoherenced, a kind of twin shaft of proposition is to the weaving method that strengthens fabric.
The invention provides following technical scheme:
Warp-knitted bi-axial strengthens the weaving method of fabric, and it comprises the steps,
The laying of a, 0 ° of orientation enhancement fiber, the yarn cylinder of fortifying fibre is placed on creel, fortifying fibre arrives warp let-off roller through tenslator Dao Ge road yarn divider, more finally is incorporated in wrap attachment through yarn divider, completes the laying of 0 ° of orientation enhancement fiber;
The laying of the fortifying fibre on b, 90 ° of directions, be placed in the yarn cylinder of fortifying fibre on creel, and the paving latitude device through tenslator Dao Ge road yarn divider to biaxial warp knitting machine is completed the laying of 90 ° of orientation enhancement fibers by paving latitude device;
C, the fortifying fibre of the fortifying fibre of 0 ° of direction and 90 ° of directions is fed to the knitting mechanism of biaxial warp knitting machine simultaneously, its binding is woven into to twin shaft to strengthening fabric.
Binding weaving manner in described c step is the loop bonding mode that warp plain stitch combines with pillar stitch.
Advantage of the present invention is that the twin shaft produced by the present invention is to strengthening fabric, during cutting, warp-wise is difficult for decoherencing, improved single shaft to the structural stability that strengthens fabric, the requirement of having avoided warp yarn to decoherence while having met the client to the bi-axial fabric cutting, greatly promoted twin shaft to the product quality that strengthens fabric, and fabric the has characteristics such as percentage elongation is little, intensity is high, good toughness.
The specific embodiment
Warp-knitted bi-axial strengthens the weaving method of fabric, and it comprises the steps,
The laying of a, 0 ° of orientation enhancement fiber, the yarn cylinder of fortifying fibre is placed on creel, fortifying fibre arrives warp let-off roller through tenslator Dao Ge road yarn divider, more finally is incorporated in wrap attachment through yarn divider, completes the laying of 0 ° of orientation enhancement fiber;
The laying of the fortifying fibre on b, 90 ° of directions, be placed in the yarn cylinder of fortifying fibre on creel, and the paving latitude device through tenslator Dao Ge road yarn divider to biaxial warp knitting machine is completed the laying of 90 ° of orientation enhancement fibers by paving latitude device;
C, the fortifying fibre of the fortifying fibre of 0 ° of direction and 90 ° of directions is fed to the knitting mechanism of biaxial warp knitting machine simultaneously, its binding is woven into to twin shaft to strengthening fabric.
Binding weaving manner in described c step is the loop bonding mode that warp plain stitch combines with pillar stitch.
Produce the technological process of twin shaft to the reinforced composite fabric: warping, upper axle, braiding, check, packing, finished product warehouse-in are woven into twin shaft to the reinforced composite fabric by bundled yarn, 0 ° of warp thread, 90 ° of weft yarns through loop-forming element.Bundled yarn is the synthetic fiber material of two kinds of specifications: GB1: low elastic polyester filament, line density: 83.3～55.5dtex, GB2: low elastic polyester filament, line density: 55.5～83.3dtex, 0 ° of direction warp thread raw material: woven glass roving fabric, line density is: below 2400tex, 90 ° of direction weft yarn raw materials: woven glass roving fabric, line density is: below 1500tex, upper secret degree is: 2.85～3.5M/cm(line/centimetre) the unit are grammes per square metre is: 800～1200g/ ㎡ plane No.: the E7 machine rotational speed is: 400～700r/min bundled yarn adopts warp plain stitch to combine with pillar stitch, 0 ° of direction and 90 ° of orientation enhancement fibers are glass fibre, synthetic fibers are polyester fiber.
Pillar stitch: every warp thread pad yarn lopping on same knitting needle all the time.Warp plain stitch: every warp thread pads the tissue of yarn lopping in turn on two knitting needles.Pillar stitch+warp plain stitch can be so that fabric be difficult for decoherencing, and structural stability is good.Because the binding mode of conventional this type of bi-axial fabric of braiding be adopt single binding, i.e. warp plain stitch, the fabric warp thread woven is easily decoherenced, and affects client's use.
