Detailed Description

The present invention will be further described with reference to the accompanying drawings and specific embodiments.

Example one

This embodiment will be described in detail with reference to fig. 1 and 2. The anti-cutting fabric related to the embodiment is a weft-knitted fabric, and the texture is weft-flat. The used raw materials are first anti-cutting covering yarns 1, namely, the raw materials used by the anti-cutting fabric are all the first anti-cutting covering yarns 1. The areal density of the cut-resistant fabric in this example was 300 grams per square meter.

Further, the first anti-cutting covered yarn 1 sequentially comprises a core yarn 3, a covered yarn 4 and a wrapping yarn from inside to outside, the covered yarn 4 completely covers the core yarn 3, and the core yarn 3 does not leak. The wrapping yarn wraps the wrapping yarn 4.

In this embodiment, the core filament 3 is a glass fiber filament, and the sheath filament 4 is an ultra-high molecular weight polyethylene filament. The core filament 3 is completely coated by the coating filament, namely the outer side of the glass fiber filament is completely covered by the ultra-high molecular weight polyethylene filament, so that the glass fiber is prevented from being exposed, and the phenomenon that the human skin is itching when encountering the glass fiber due to the fact that the glass fiber cannot be completely coated because the middle layer yarn is not available in the traditional process is effectively avoided. The fineness of the glass fiber filaments was 100 tex. The fineness of the ultra-high molecular weight polyethylene filaments is 200D to 400D, and 200D is selected in the embodiment.

The wrapping filaments include a Z-direction wrapping filament 5 and an S-direction wrapping filament 6. The wrapping yarn is polyester filament yarn or nylon filament yarn, and in the embodiment, the Z-direction wrapping yarn 5 and the S-direction wrapping yarn 6 are both selected to be black polyester filament yarn. The pitch of the Z-direction wrapping wire 5 and the S-direction wrapping wire 6 is 5 to 10 times the diameter of the wrapping wire, and 5 times is selected in this embodiment. The wrapping yarn functions to improve the wear resistance of the cut wrap yarn and improve the appearance of the prepared fabric, so that the fabric looks similar to a conventional fabric.

Example two

This embodiment will be described in detail with reference to fig. 2, 3, and 4. The area density of the anti-cutting fabric related to the embodiment is 500 grams per square meter, and the difference from the embodiment one is that:

the raw material used also comprises a second cut-resistant covering yarn 2. And the first cutting-proof covering yarn 1 and the second cutting-proof covering yarn 2 are arranged alternately, namely one first cutting-proof covering yarn 1 and one second cutting-proof covering yarn 2 in one circulation.

The second cutting-prevention covering yarn 2 used differs from the first cutting-prevention covering yarn 1 in that the wrapping filaments include two Z-direction wrapping filaments 5 and two S-direction wrapping filaments 6, i.e., four wrapping filaments on the outer side of the wrapping filaments. And the Z-direction wrapping yarn 5 is selected as a polyester filament yarn, the S-direction wrapping yarn 6 is selected as a nylon filament yarn, and the colors are all selected as grey.

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. The pitch of the Z-direction wrapping wire 5 and the S-direction wrapping wire 6 is 5 to 10 times, in this embodiment, 10 times the diameter of the wrapping wire.

The anti-cutting fabric prepared in the first embodiment and the second embodiment can reach 5 levels of EN388:2016, the highest level, through tests.

The results of knife cut resistance as measured by intetek corporation are shown in the following table:

In the european standard EN388:2016, the minimum requirement for a level 5 cut according to the standard test method is 20.0. The fabrics produced in both examples one and two meet the specification of level 5, which is the highest standard in european standard EN388:2016, level 5.

Further, the arrangement order of the first cut-preventing covering yarn 1 and the second cut-preventing covering yarn 2 in the cut-preventing fabric is not 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 second cut-preventing covering yarn 2 may even be used entirely.

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.
