Description

Anti-cutting covered yarn

Technical Field

The utility model relates to a weaving yarn technical field especially relates to a prevent cutting cladding yarn.

Background

There are two main types of cut resistant yarns available in the prior art: one is a covered yarn mainly made of aramid fiber, and the other is an anti-cutting covered yarn mainly made of superfine stainless steel wires and combined with polyester low-stretch yarn for covering. The raw and auxiliary materials of the first wrapping yarn are extremely high in price, the cutting resistance of a finished product is not ideal, and obvious scratches can be generated when the product is cut by a sharp object; the second kind is cheap, but the finished product that makes feels hard, the part weight, the net weight of a stab-resistant suit can reach about 3KG, is not suitable for general colony to wear; moreover, the appearance looks significantly different than ordinary clothes, is easily noticeable and has no concealment.

SUMMERY OF THE UTILITY MODEL

The utility model aims at providing a prevent cutting cladding yarn not only has higher cutting performance of preventing, still makes the clothing that makes similar with conventional clothing.

In order to solve the technical problem, the purpose of the utility model is to realize like this:

the utility model relates to an anti-cutting covered yarn, which comprises a core wire, a covering wire and a wrapping wire from inside to outside in sequence; the core wire is completely coated by the coating wire, and the core wire does not leak; the wrapping silk wraps the wrapping silk; the core filament is a glass fiber filament, the cladding filament is an ultra-high molecular weight polyethylene filament, and the wrapping filament comprises a Z-direction wrapping filament and an S-direction wrapping filament.

As a further illustration of the above scenario, the sum of the deniers of the Z-wrap and S-wrap is 150D.

As a further explanation of the above scheme, the wrapping yarn is polyester filament yarn or nylon filament yarn.

As a further explanation of the above scheme, the fineness of the glass fiber filaments is 100 tex.

As a further explanation of the above scheme, the fineness of the ultra-high molecular weight polyethylene filaments is 200D-400D.

The utility model has the advantages that: the utility model relates to a prevent cutting cladding yarn has used glass fiber filament, cladding silk to have used ultra high molecular weight polyethylene filament at the core silk, not only makes when having the cutting performance of preventing, still makes this cladding yarn cover glass completely, prevents that glass fiber from exposing, has effectively avoided traditional handicraft not to have middle level yarn, can not wrap glass fiber completely, and glass fiber exposes the human skin that leads to and meets glass fiber and produce the phenomenon of scratchiness.

FIG. 1 is a schematic structural diagram of the first embodiment;

FIG. 2 is a schematic structural diagram of the second embodiment.

The designations in the figures illustrate the following: 1-core filament; 2-coating silk; wrapping the silk in the 31-Z direction; wrapping the silk in the 32-S direction.

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. The anti-cutting covered yarn comprises a core yarn 1, a covering yarn 2 and a wrapping yarn from inside to outside in sequence. The covering wire 2 completely covers the core wire 1, so that the core wire 1 does not leak. The wrapping filament wraps the wrapping filament 2, i.e., the wrapping filament is located outside the wrapping filament 2.

The core yarn 1 used in this example was a glass fiber filament with a fineness of 100 tex. The used coating filament 2 is an ultra-high molecular weight polyethylene filament with the fineness of 200-400D, and in the embodiment, the fineness is selected to be 400D. The wrapping filaments include a Z-direction wrapping filament 31 and an S-direction wrapping filament 32. The sum of the deniers of the Z-wrapping yarn 31 and the S-wrapping yarn 32 is 150D. In the present embodiment, the fineness of the Z-direction wrapping yarn 31 and the fineness of the S-direction wrapping yarn 32 are the same and are both 75D. The pitch of the Z-direction wrapping wire 31 and the S-direction wrapping wire 32 is 5 to 10 times, in this embodiment, 5 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 31 and the S-direction wrapping yarn 32 are both selected to be polyester, and are black in color. 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. One of the differences between the cut-preventing covered yarn according to this embodiment and the embodiment is that the ultra-high-molecular-weight polyethylene filaments used have a fineness of 200D. The other difference is that the Z-direction wrapping yarn 31 and the S-direction wrapping yarn 32 are both two, namely four wrapping yarns are arranged on the outer side of the wrapping yarn 2, the Z-direction wrapping yarn 31 is selected to be a polyester filament yarn, the S-direction wrapping yarn 32 is selected to be a nylon filament yarn, and the colors of the Z-direction wrapping yarn and the S-direction wrapping yarn are both selected to be 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. The pitch of the Z-wrapping wire 31 and the S-wrapping wire 32 is 5 to 10 times, in this embodiment, 10 times the diameter of the wrapping wire.

In this embodiment, the two Z-direction wrapping filaments 31 and the two S-direction wrapping filaments 32 can effectively improve the wear resistance of the anti-cutting wrapping yarn, and have better wear resistance than the anti-cutting wrapping yarn prepared in the first embodiment.

The garment materials prepared from the anti-cutting covered yarns prepared in the first embodiment and the second embodiment can reach 5 grades of European standard EN388:2016, which is the highest grade.

The results of the knife-cut resistance measured by INTERTEK 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.

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.
