Technical Field

The invention relates to the technical field of protective fabrics, in particular to a high-cut-resistant fabric with a double-layer structure.

Background

In order to meet the working requirements of special industries, different functional fabrics need to be customized. For example, the fabric of the clothing for firefighters needs to have flame retardant properties, cut resistance, and also a certain comfort.

The prior Chinese patent with publication number CN206124334U discloses a flame-retardant water-absorbing humidity-sensitive textile, wherein the fabric used by the textile comprises at least 3 layers of structures, namely a humidity-sensitive material layer, a flame-retardant water-permeable layer and a flame-retardant water-absorbing layer from outside to inside, and the flame-retardant water-absorbing layer is used for improving the thermal stability of a non-woven fabric containing water-absorbing materials by mixing water-absorbing fibers and flame-retardant fibers, so that the safety of a user is improved. This is the functional fabric that applicant developed for firefighter protective clothing before, but the problem that exists in the actual manufacturing is: firstly, the number of piles is more, and soft comfort level is relatively poor, secondly does not do resistant cutting consideration at that time, and the anti-cutting grade of fabrics is not high.

Based on the situation, a new functional fabric which has the advantages of cutting resistance, softness and good comfort and is suitable for protective clothing in special industries needs to be developed urgently.

Disclosure of Invention

Aiming at the defects in the prior art, the invention aims to provide a high-cut-resistant fabric with a double-layer structure.

The above object of the present invention is achieved by the following techniqueThe scheme is realized as follows: the utility model provides a bilayer structure's high anti-cutting surface fabric, high anti-cutting surface fabric includes two-layer, upper and lower interconnect between two-layer, its characterized in that: one layer adopts a cutting-resistant fabric layer (1), the cutting-resistant grade of the high-cut-resistant fabric is American standard ANSI cutting-resistant grade 2-9 grade, ISO13997 grade B-F grade, and the gram weight of the high-cut-resistant fabric is 200-700 g/m²。

Through adopting above-mentioned technical scheme, provide a new high anti-cutting surface fabric, be different from prior art's multilayer, the number of piles is still less, and the preparation is convenient, and ventilative comfort level is good. After one layer is a cutting-resistant fabric layer, the overall gram weight of the high-cut-resistant fabric can reach 200-700 g/m²And the cutting-resistant grade of the high-cutting-resistant fabric can be effectively enhanced. The fabric in the gram weight range is good in finishing quality and high in anti-cutting performance level.

The present invention in a preferred example may be further configured to: the high-cut-resistant fabric has the cut-resistant grades of American standard ANSI (American national standards institute) cut-resistant grade 2-5 and ISO13997 grade B-E: the other layer of the high anti-cutting fabric is a comfortable layer and is formed by weaving polyester yarns or polyester blended yarns, and the polyester blended yarns are formed by one or more of polyester blended cotton, acrylic fibers, spandex and nylon.

By adopting the technical scheme, when the other layer is woven by pure polyester yarns or polyester blended yarns, the obtained fabric has the advantages of wear resistance, flexibility and elasticity, and high overall comfort level after the protective clothing is manufactured.

The present invention in a preferred example may be further configured to: the side of the comfortable layer close to the skin is coated with a strip-shaped fibroin coating.

By adopting the technical scheme, the comfortable layer close to the skin has skin-friendly property and air permeability, and the wearing feeling of a person is more comfortable after the fabric is made into the protective clothing.

The present invention in a preferred example may be further configured to: the high-cut-resistant fabric has the cut-resistant grades of American standard ANSI (American national standards institute) cut-resistant grade 6-9 and ISO13997 grade F: the other layer of the high anti-cutting fabric is a covering yarn layer and is formed by weaving mineral fiber covering yarns, and the mineral fiber covering yarns are formed by mineral fibers and one or more of cotton, acrylic fibers, spandex, nylon and terylene through a covering process.

By adopting the technical scheme, when the other layer is woven by pure glass fiber or glass fiber coated yarns, the cutting-resistant grade of the fabric is enhanced again due to the high strength and high modulus of the glass fiber.

The present invention in a preferred example may be further configured to: one surface of the covering yarn layer close to the skin is coated with a strip-shaped fibroin coating.

By adopting the technical scheme, the coating yarn layer close to the skin has skin-friendly property and air permeability, and a product made of the fabric is more comfortable to wear in summer.

The present invention in a preferred example may be further configured to: the cutting-resistant fabric layer is formed by weaving covering yarns or covering yarns, the covering yarns or the covering yarns comprise covering yarns and core yarns, the covering yarns at least comprise aramid fibers 1414 or polyethylene, and the core yarns are metal wires with the thickness of 10-80 micrometers or mineral fiber filaments with the thickness of 50-400D.

By adopting the technical scheme, the raw material of the cutting-resistant fabric layer is convenient to obtain, the performance is stable, and the finished product rate of the manufactured fabric is high. Among them, aramid 1414 can provide flame retardant properties and polyethylene can provide wear resistance.

The present invention in a preferred example may be further configured to: and a thermoplastic glue block or a spot bead hot glue coating layer is bonded on one surface of the cutting-resistant fabric layer close to the other layer.

By adopting the technical scheme, the thermoplastic rubber block and the hot coating rubber can ensure that the connection between the comfortable layer or the covering yarn layer and the cutting-resistant cloth layer is firmer. Besides, the thermoplastic block and the hot glue also have the following functions: firstly, because of the laminating is inseparable, the whole compacter of high anti-cutting surface fabric is flat, secondly the tie coat can let resistant cutting bed of cloth's anti-cutting ability stronger.

The present invention in a preferred example may be further configured to: and a leather layer is sewn on one surface of the cutting-resistant fabric layer, which is far away from the other layer.

By adopting the technical scheme, the leather has certain elasticity, after the leather is stretched to a certain length, the resilience does not linearly generate along with the elimination of external force, but slowly recovers according to a specific curve, and the mechanical property of the slow resilience can ensure that the protective clothing made of the fabric is more comfortable to wear and is attached to the body without oppression to the body. In addition, the leather has good air permeability and moisture absorption and discharge.

In summary, the invention includes at least one of the following beneficial technical effects:

1. by arranging the cutting-resistant fabric layer and the comfortable layer/covering yarn layer, the cutting-resistant fabric can provide the cutting-resistant protection effect for the fabric, and the cutting-resistant protection effect is doubled;
