The present embodiment will be described in detail with reference to fig. 1 and 3. The cutting-resistant and stab-resistant composite fabric comprises a cutting-resistant fabric 1, an interlayer fabric 2 and a lining layer 3; the raw material used by the interlayer fabric 2 is ultra-high molecular weight polyethylene filament; the anti-cutting fabric 1 is a weft-knitted fabric taking the anti-cutting covered yarn 5 as a raw material,
the areal density of the interlayer fabric 2 is 500-700 grams per square meter, and in the embodiment, 500 grams per square meter is selected. The surface density of the anti-cutting fabric 1 is 200 and 500 grams per square meter, and in the embodiment, the surface density is 500 grams per square meter. The face width of the backing layer 3 is 30-50 grams per square meter, in this embodiment 30 grams per square meter is chosen. The interlayer fabric is a weft knitting fabric knitted by an ultra-high molecular weight polyethylene filament warp circular knitting machine.
A composite layer 4 is arranged outside the anti-cutting fabric 1. The composite layer 4 can be white fabric, and the white fabric used for preparing the white gown of the medical care personnel. When the white fabric is used, the white fabric can be used for preparing a puncture-proof garment worn by medical personnel for protecting the medical personnel, the white fabric is used on the outer side, looks the same as a conventional medical white gown in appearance, has strong concealment, and can effectively protect the medical personnel on the premise of not causing panic of a patient when the medical personnel wear the white gown.
The cut-preventing covered yarn 5 includes, in order from the inside to the outside, a core 51, a covered filament 52, and a covered filament. The covering wire 52 completely covers the core wire 51 so that the core wire 51 does not leak. The wrapping filament wraps the wrapping filament 52, i.e., the wrapping filament is located outside the wrapping filament 52.
The core yarn 51 used in this example was a glass fiber filament having a fineness of 100 tex. The used coating filament 52 is an ultra-high molecular weight polyethylene filament with the fineness of 200-400D, and in the embodiment, 400D is selected. The wrapping filaments include Z-direction wrapping filaments 531 and S-direction wrapping filaments 532. The sum of the deniers of the Z-direction wrapping yarn 531 and the S-direction wrapping yarn 532 is 150D. In the present embodiment, the fineness of the Z-direction wrapping filament 531 and the fineness of the S-direction wrapping filament 532 are both 75D. The pitch of the Z-direction wrapping wire 531 and the S-direction wrapping wire 532 is 5 to 10 times the diameter of the wrapping wire.
Furthermore, the wrapping yarn is polyester filament yarn or nylon filament yarn. In the present embodiment, the Z-direction wrapping yarn 531 and the S-direction wrapping yarn 532 are both selected to be polyester, and are black in color.
Example two
This embodiment will be described in detail with reference to fig. 2. The difference between the cutting-resistant and stab-resistant composite fabric related to the embodiment and the embodiment is as follows:
the areal density of the interlayer fabric 2 is 500-700 g/m, in this embodiment 700 g/m. The surface density of the anti-cutting fabric 1 is 200 and 500 grams per square meter, and 200 grams per square meter is selected in the embodiment. The areal density of the backing layer 3 is 30-50 grams per square meter, in this embodiment 50 grams per square meter is selected.
The ultra-high molecular weight polyethylene filaments used in the cut-resistant covering yarn 5 had a fineness of 200D. The other difference is that the Z-direction wrapping yarn 531 and the S-direction wrapping yarn 532 are both two, that is, four wrapping yarns are arranged on the outer side of the wrapping yarn 52, the Z-direction wrapping yarn 531 is selected as a polyester filament yarn, the S-direction wrapping yarn 532 is selected as a nylon filament yarn, and the colors of the filaments are both selected as gray. The fineness of the selected polyester filament and nylon filament is 75D. Alternatively, the polyester filaments may be selected to be 50D and the nylon filaments to be 100D.
A composite layer 4 is arranged outside the anti-cutting fabric 1. The composite layer 4 is black common fabric or camouflage fabric; when the fabric is black, the fabric can be used as protective clothing with strong concealment such as jackets. When the jacket is worn by security personnel, the jacket can be hidden in people, and has strong concealment. When the composite layer 4 is made of camouflage fabric, the camouflage fabric can be used as a camouflage bag or camouflage clothing, so that the camouflage bag or the camouflage clothing has a good stab-resistant function, and the clothing made of the fabric is lighter than the existing stab-resistant clothing, and can reduce the load of military and police personnel.
The results of the blade Cut Resistance of the Cut resistant fabrics of examples one and two, as measured by intetek corporation, are shown in the following table:
| I1 | I2 | I3 | I4 | I5 | mean value of | |
| Example one | ﹥22.8 | ﹥22.8 | ﹥22.8 | ﹥22.8 | ﹥22.8 | ﹥22.8 |
| Example two | ﹥21.0 | ﹥21.0 | ﹥21.0 | ﹥21.0 | ﹥21.0 | ﹥21.0 |
In the european standard EN388:2016, the minimum requirement for a level 5 cut according to the standard test method is 20.0. The cut resistant fabrics in both examples one and two meet the specification of level 5, which is the highest standard in european standard EN388: 2016.
The interlayer fabrics prepared by the ultra-high molecular weight polyethylene filaments are arranged in the first embodiment and the second embodiment, so that the interlayer fabrics have good performance in the aspect of puncture resistance. And the effect of non-penetration is achieved through the detection of the security of the police department and the quality detection center of the police electronic product.
The cut-preventing covering yarn referred to in example one was named a first cut-preventing covering yarn, and the cut-preventing covering yarn referred to in example two was named a second cut-preventing covering yarn. In the first embodiment, the cutting-resistant fabric is formed by weft knitting of the first cutting-resistant covering yarn, and in the second embodiment, the cutting-resistant fabric is formed by weft knitting of the second cutting-resistant covering yarn.
Furthermore, the anti-cutting fabric in the stab-resistant and bulletproof vest is formed by weft knitting the first anti-cutting wrap yarn and the second anti-cutting wrap yarn, and the arrangement sequence of the two anti-cutting wrap yarns may not be limited to 1: 1, may also be 1: 2. 1: 3. 1: 4, or 2: 1. 3: 1. 4: 1, more preferably 2: 2. 2: 3. 3: 3, and other arrangements and ratios. The anti-cutting fabric can have different performances. The so-called arrangement order is 1: the arrangement rule of the two yarns is that one first anti-cutting covering yarn and one second anti-cutting covering yarn.
The foregoing has described in detail preferred embodiments of the present invention. It should be understood that numerous modifications and variations can be devised by those skilled in the art in light of the present teachings without departing from the inventive concepts. Therefore, the technical solutions that can be obtained by a person skilled in the art through logic analysis, reasoning or limited experiments based on the prior art according to the concepts of the present invention should be within the scope of protection defined by the claims.
