According to the scheme, on the premise that the whole thickness of the anti-stab sheet is not increased, the anti-stab sheet is divided into a plurality of layers, each layer of anti-stab sheet is adhered to one base cloth, and then the base cloth with the anti-stab sheet is arranged in a laminated mode; and the base cloth exists between every layer of the anti-stab sheet, and the arrangement of the multiple layers of the base cloth also contributes to the anti-stab resistance of the gap, so that the safety performance is further improved.
In order to prove that the multilayer stacked stab-resistant fabric has a better effect on stab resistance, the applicant adopts the public security department stab-resistant test standard GA68-2008, under the 24 Joule stab-resistant test strength condition, the thickness of the stab-resistant sheet on the original single-layer structure stab-resistant fabric needs to be 4.3mm to meet the condition, and by adopting the three-layer stacked stab-resistant fabric, the stab-resistant requirement can be met only by making the whole thickness to be 3.3mm, the stab-resistant fabric meeting the equal stab-resistant grade requirement is greatly reduced in the whole thickness, the weight of the fabric is greatly reduced, and the comfort level of a wearer is improved.
Example three:
referring to fig. 3, 4-7, the present embodiment is a laminated stab-resistant fabric 30 with a high safety factor, which includes a first base fabric 31, a plurality of first stab-resistant sheets 32 disposed on the first base fabric 31, a second base fabric 33 covering the first stab-resistant sheets 32, a plurality of second stab-resistant sheets 34 fixedly disposed on the second base fabric 33, a third base fabric 35 covering the second stab-resistant sheets 34, a plurality of third stab-resistant sheets 36 fixedly disposed on the third base fabric 35, a fourth base fabric 37 covering the third stab-resistant sheets 36, and a plurality of fourth stab-resistant sheets 38 fixedly disposed on the fourth base fabric 37, wherein the positions of the first stab-resistant sheets 32, the second stab-resistant sheets 34, the third stab-resistant sheets 36, and the fourth stab-resistant sheets 38 are disposed in a vertical direction.
Gaps 39 are formed between adjacent two first puncture-proof sheets 32, between adjacent two second puncture-proof sheets 34, between adjacent two third puncture-proof sheets 36, and between adjacent two fourth puncture-proof sheets 38. The upper and lower positions of the gap 39 in the two adjacent anti-prick layers are correspondingly arranged.
