Embodiment 1

[0030] The production process is: yarn preparation—knitting on the machine—finishing—composite layering—cutting—edge wrapping, sparse quilting—knitting flexible composite anti-stab vest fabric;

[0031] The preparation of the yarn is as follows: using 300D ultra-high molecular weight polyethylene yarn as a raw material for winding;

[0032] The knitting on the upper machine is as follows: a weft flat knitting machine is used to weave the weft flat stitch, and the loop length is 4.2mm;

[0033] The finishing is as follows: plain knitted fabric: cold and hot water washing; coated weft plain knitted fabric: cold and hot water washing—coating treatment. Cold and hot water cleaning is carried out according to the conventional process; the coating treatment uses aluminum oxide particles with a particle size of 50um, mixed with polyurethane and polyacrylate copolyester composite emulsion at a weight ratio of 2.5:1, and the coating thickness is 0.2mm;

[0034] The composite lay-up is...

Embodiment 2

[0038] The production process is: yarn preparation—knitting on the machine—finishing—composite layering—cutting—edge wrapping, sparse quilting—knitting flexible composite anti-stab vest fabric;

[0039] The preparation of the yarn is as follows: using 300D ultra-high molecular weight polyethylene yarn as a raw material for warping;

[0040] The knitting on the upper machine is as follows: warp-knitting single-needle bed Raschel machine is used to weave warp and satin weave, and the loop length is 4.3mm;

[0041] The finishing is as follows: warp satin fabric: cold and hot water washing; coated warp satin fabric: cold and hot water washing—coating treatment. Cold and hot water cleaning is carried out according to the conventional process; the coating treatment uses aluminum oxide particles with a particle size of 30um, mixed with polyurethane and polyacrylate copolyester composite emulsion at a weight ratio of 3.0:1, and the coating thickness is 0.3mm;

[0042] The composite l...

Embodiment 3

[0046] Preparation method is the same as embodiment 1 and embodiment 2, and difference is as follows:

[0047] The composite layer is as follows: the anti-stab vest fabric layer from the outside to the inside is: 3 layers of coated warp satin fabric layer - 6 layers of non-woven fabric layer - 6 layers of weft jersey fabric layer - 2 layers No weft layer - 2 layers of weft jersey fabric. Among them, the 3-layer coated warp satin fabric has part of the process reversed outwards and is stacked at 120 degrees; the 6-layer weft jersey fabric is part of the process reversed outwards and is stacked at 60 degrees; 2 layers of non-weft fabric are 90 degrees crossed Stacking; 2 layers of weft jersey fabric part of the reverse side of the process, 180 degrees cross-stacked;

[0048] The anti-stab fabric after composite layering is cut according to the specifications of the vest, and then bound with weft jersey fabric and sparsely quilted.

[0049] The warp-knitted and weft-knitted fle...

Abstract

The invention relates to a method for manufacturing a knitted soft composite stabproof vest fabric, which belongs to the field of methods for manufacturing stabproof vest fabrics. The method comprises the following steps of: (1) performing weft knitting spooling or tricot warping by adopting ultrahigh molecular weight polyethylene yarns or aramid fibers as raw materials; (2) knitting the yarns by adopting a circular weft knitting machine and a flat knitting machine or knitting the yarns by adopting a warp knitting machine; (3) washing the knitted fabric obtained by the knitting with cold water and hot water, and then performing coating treatment; (4) layering the finished knitted fabric, ultrahigh molecular weight polyethylene non-woven and a laid fabric; and (5) shearing the layered fabric, serging and quilting seam with rough stitches to obtain the knitted soft composite stabproof vest fabric. The method of the invention has the advantages of improving the shearing resistance of the soft stabproof layer of the obtained fabric, reducing the piercing depth of a cutting edge in the soft stabproof layer and effectively improving the interface strength and uniformity of the coating treatment, along with simplicity and suitability for industrial production; and the obtained fabric is light, soft and comfortable to use.

Description

technical field [0001] The invention belongs to the field of production methods of stab-proof vest fabrics, in particular to a production method of knitted flexible composite stab-proof vest fabrics. Background technique [0002] Anti-stab clothing is a kind of anti-stab personal armor used to protect the human body from sharp objects such as bayonets and daggers. According to the rigidity and flexibility of the main stab-resistant material, stab-resistant clothing can be divided into three types of stab-resistant clothing: rigid, semi-rigid and flexible. [0003] Stab-resistant personal armor is required to ensure the wearer's freedom of movement while performing official activities. Rigid and semi-rigid stab-resistant clothing contain rigid stab-resistant materials such as metal wires, metal meshes, and ceramic sheets, which have excellent penetration resistance, but have shortcomings such as heavy weight, uncomfortable wearing, and restricted movement; the stab-resistant...
