Accompanying violent incidents occur frequently in various countries, and violent incidents such as fire, holding of instruments, and carrying of various tools occur in various parts of the world.

The protective equipment including the stab-resistant armor and the bullet-proof armor can protect the main trunk of the upper half of the human body, and the bullet-proof and explosion-proof helmet can protect the head from fatal injuries, but the neck, the face and the head cannot protect the cutting injury of ruffians. In addition, when ordinary people escape in riot, the people often need to prevent the damage of flame and dense smoke. For example, riots occurring in the middle east, uk, france and india are often associated with fire-in-the-middle events, and particularly head protection is required with cut-resistant, flame-retardant headgear. In the fields of fire fighting and police, a wearer needs to quickly adjust the fireproof headgear according to the head height, the neck length, the relative position of shoulders and the height of the wearer, and the wearing is finished in the shortest time; in addition, in a complex high-temperature flame emergency environment, the headgear needs to be kept stable to prevent splashing spark flames from entering the headgear.

In addition to and as a preferred embodiment of the above embodiment, a layer of flame retardant is attached to the outer layer. The flame retardant is attached to the outer layer, so that the flame retardant performance of the headgear can be improved, and the headgear has the effects of cutting resistance and puncture resistance and also has the flame retardant performance.

In addition to the above, as a preferable mode of the above, the upper part of the headgear body is shaped like a human head, and the lower part is in the form of a cape. The design accords with the human body structure, and the design is more humanized.

The utility model has the advantages that: compared with the prior art, the utility model discloses a dacron cladding ultra high molecular weight polyethylene filament and gain better anti-cutting and prevent thorn effect, wear comfortable soft, can fold in a flexible way, can also use as the cold-proof headgear of ordinary head. And a layer of flame retardant is attached to the outer layer, so that the headgear has an excellent flame retardant effect. Is suitable for extreme occasions such as fire, fire control, violence and the like. The utility model has the advantages of simple structure, reasonable design, good warm-keeping effect, cutting and puncture resistance and flame retardance.

Detailed Description

Reference will now be made in detail to embodiments of the present invention, examples of which are illustrated in the accompanying drawings, wherein like reference numerals refer to the same or similar elements or elements having the same or similar function throughout. The embodiments described below with reference to the accompanying drawings are exemplary only for the purpose of explaining the present invention, and should not be construed as limiting the present invention.

In the description of the present invention, it is to be noted that, unless otherwise explicitly specified or limited, the terms "mounted," "connected," and "connected" are to be construed broadly, and may be, for example, fixedly connected, detachably connected, or integrally connected; may be mechanically connected, may be electrically connected or may be in communication with each other; either directly or indirectly through intervening media, either internally or in any other relationship. The specific meaning of the above terms in the present invention can be understood according to specific situations by those skilled in the art.

As shown in fig. 1-3, a flame retardant protective headgear comprises a headgear body 1, wherein the headgear body 1 comprises an inner layer 2 close to one side of a user and an outer layer 3 far away from one side of the user; an opening 4 is formed in one surface of the head cover main body 1; the inner layer 2 is formed by weaving ultra-high molecular weight polyethylene filaments; the outer layer 3 is formed by weaving wrapping yarns; the wrapping yarn sequentially comprises a core yarn 5 and a polyester wrapping yarn from inside to outside, wherein the core yarn 5 is an ultrahigh molecular weight polyethylene filament.

Specifically, the polyester coated yarns comprise Z-direction coated yarns 6 and S-direction coated yarns 7. The ultra-high molecular weight polyethylene chain structure is a typical linear structure, has few branched chains far lower than common polyethylene, has less than 1/1000 branch points, and has ultra-long macromolecular chains reaching tens of thousands of nanometers, so the ultra-high molecular weight polyethylene chain structure is an ideal material for preparing flexible chain high-strength fibers. In order to prevent the invasion of sharp objects, particularly in the environments of overspeed sports and emergent events, the research and development of a high-cutting-resistance fiber and a woven product thereof (such as various military and civil facilities, clothes, hats, gloves and foot sleeves and the like) are always attracted by the attention of the domestic and foreign industries. The ultra-high molecular weight polyethylene fiber is one of three high-tech fibers, is a fiber with the highest specific strength which is already commercially produced, and is mainly applied to the fields of safety protection, aviation, weaponry, sports and the like. The anti-cutting and anti-puncturing fabric woven by the ultra-high molecular weight polyethylene fibers can bear the impact and friction of metal and the like, and can effectively protect the safety of a user. Further, the fineness of the ultra-high molecular weight polyethylene filament is 200D-400D. More specifically, the inner layer 2 and the outer layer 3 are weft-knitted fabrics.

Still further, a layer of flame retardant is attached to the outer layer 3. The flame retardant is attached to the outer layer, so that the flame retardant performance of the headgear can be improved, and the headgear has the effects of cutting resistance and puncture resistance and also has the flame retardant performance. Furthermore, the upper part of the head cover body 1 is in the shape of a human head, and the lower part is in the shape of a cape. The design accords with the human body structure, is more fit with the head of a person and is more humanized.

The utility model discloses the concrete connection mode does:

the outer layer 3 that weaves the cladding yarn and the inlayer 2 that forms that ultra high molecular weight polyethylene filament was woven overlap and place on the workstation, make up or fix with other modes along headgear design profile, obtain a fire-retardant protection headgear.

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.
