Technical Field

The invention relates to a protective product, in particular to comfortable bulletproof stab-resistant functional clothing.

Background

The bulletproof stab-resistant functional clothing is also a bulletproof stab-resistant clothing, and has a bulletproof function and a stab-resistant function as well as an individual protection product as the name suggests. For body armor and stab-resistant armor, the bulletproof mechanism and stab-resistant mechanism of the material are different, the bulletproof mainly depends on the tensile breaking strength of the material, the higher the tensile strength of the material is, the more energy of projectiles such as bullets or fragments and the like which are impacted at high speed is dissipated in the process of impacting the material and breaking/stretching the material, so that the projectiles are deformed and prevented from advancing; in the process of preventing the stabs, the stabs are a low-speed continuous process, the shearing strength of the material is higher, the deformation of the tool nose is quicker, and the sharp device can be prevented from continuously moving forwards, so that the protection purpose is achieved. In general, bulletproof and stab-resistant are contradictory, and materials with good bulletproof performance generally have poor stab-resistant performance, while materials with good stab-resistant performance generally have poor bulletproof performance. In recent years, research and development of bulletproof and stab-resistant functional clothes are greatly advanced at home and abroad, but in view of mechanism difference, products are mostly in the forms of multi-structure superposition, multi-material combination and the like of stab-resistant materials and bulletproof materials, and the superposition combination of multiple materials can often improve the weight of the bulletproof and stab-resistant clothes. At present, the bullet-proof and stab-proof functional clothes with the publication numbers CN 102788531A and CN101881582a combine the material with bullet-proof function and the material with stab-proof function, and the difference is that the bullet-proof and stab-proof functional clothes with the publication number CN 102788531A combine the bullet-proof material and stab-proof material in one layer by certain measures, and the bullet-proof and stab-proof functional clothes with the publication number CN101881582A simply combine the bullet-proof material and stab-proof material in one chip.

In addition to being heavier, the combination of ballistic and stab resistant materials also tends to be less than optimal in softness. If the performance of the bullet-proof vest and the stab-resistant vest can be combined into a whole, a balance point is found among effective protection, comfort, softness and light weight, comprehensive protection efficiency can be realized on a single structure and material, and a soft comfortable protection product is formed. At present, the comfortable soft bulletproof stab-resistant functional clothes made of only one single structure and material are not reported.

Disclosure of Invention

Aiming at the defects, the invention provides comfortable bulletproof and stab-resistant functional clothing which is used for overcoming the defects of heavy weight and poor comfort caused by simply combining bulletproof materials and stab-resistant materials in the prior art.

The invention provides comfortable bulletproof and stab-resistant functional clothes, which comprise a coat and a bulletproof and stab-resistant material arranged in the coat, wherein the bulletproof and stab-resistant material comprises a bulletproof and stab-resistant chip and a buffer material;

the bulletproof and stab-resistant chip is formed by orthogonally stacking up to 40 laminated plate cloths according to the angle of 0 degree/90 degrees, and the laminated plate cloths are formed by pressing laid fabrics;

the non-woven cloth is formed by bonding fiber yarns through an adhesive.

The bulletproof stab-resistant functional garment provided by the invention has a bulletproof effect and a stab-resistant effect. The bulletproof stab-resistant functional garment of the invention mainly exerts bulletproof stab-resistant effects through the bulletproof stab-resistant core sheet, wherein the manufacturing process of the bulletproof stab-resistant functional garment is divided into three steps of processes, and firstly, fiber yarns are bonded by an adhesive to obtain fiber cloth; then, orthogonally superposing the two layers of fiber cloth to obtain the weftless fabric; and finally, pressing the laid fabric to obtain laminated board cloth, and orthogonally combining the plurality of laminated board cloths to obtain the bulletproof and stab-resistant chip.

When the fiber cloth is generated initially, the basic requirements of bulletproof and stab-resistant performance are met through the combination of the fiber yarns with specific performance and the adhesive, so that the weftless cloth can be obtained only by orthogonal superposition of two layers of fiber cloth in the subsequent manufacturing process, and the bulletproof and stab-resistant chip can be obtained by orthogonal superposition of at most 40 layers of laminated cloth.

Specifically, the number of layers of the platen cloth can be specifically determined according to the protection effect required. For example, when the bulletproof and stab-resistant-1 level of the public security department is met, the number of required layers of the pressing plate cloth is 20-30; when the requirement of the public security department on bulletproof and stab resistance is met, the number of required layers of the pressing plate cloth is 30-40. Generally, when the number of layers of the laminated cloth is 30, the bulletproof and stab-resistant effect can be met. And the cushioning material may be selected from comfort elastomers such as EVA, XPE, and the like.

The bulletproof stab-resistant functional garment does not simply splice and combine materials with stab-resistant and bulletproof functions, but obtains a single bulletproof stab-resistant material with stab-resistant and bulletproof effects by using specific fiber yarns and adhesives as initial raw materials and processing the raw materials in a special sequence, and the single bulletproof stab-resistant material can simultaneously meet the requirements of bulletproof stab-resistant effects. Meanwhile, the bulletproof and stab-resistant material not only has bulletproof and stab-resistant effects, but also is softer and more comfortable due to the abandoning of a combination mode of multiple functional materials, and the safety, flexibility and comfort of users are obviously improved.

Further, the adhesive is selected from one or more of waterborne polyurethane, waterborne polyvinyl acetate, waterborne polyolefin adhesive and waterborne acrylate. After a great deal of research by the inventor, the adhesive or the composition thereof can absorb external energy after being produced into the fiber cloth, and the impact strength of the fiber cloth is obviously improved.

Further, the mass percent of the fiber yarn in the fiber cloth is 70-85%, and the mass percent of the adhesive in the fiber cloth is 15-30%. In order to further improve the bulletproof and stab-resistant effect of the bulletproof and stab-resistant functional clothing, the manufacturing process of the fiber cloth can be controlled during manufacturing, and particularly, the use ratio of the fiber yarns and the adhesive can be controlled. When the use ratio of the cellosilk and the adhesive is controlled within the range, the use strength of the fiber cloth is obviously improved, so that the laid cloth can be obtained only by orthogonal superposition of two layers of fiber cloth in the manufacturing process of the bulletproof stab-resistant chip, and over-elaborate operation of improving the material density through multilayer superposition and multi-angle superposition to achieve the protection effect in the prior art is avoided.

Further, the solid content of the adhesive is 20-50%. In the adhesive, the water accounts for the rest except the effective components of the adhesive, and the viscosity of the adhesive can reach 50-300 mPa.s and the pH value reaches 6-9 by controlling the solid content of the adhesive within the range. Wherein, this viscosity can further guarantee adhesive and cellosilk glue and glue the intensity that becomes the fiber cloth, and this pH value can guarantee the infiltration nature of adhesive to the cellosilk, further strengthens sticky effect.

Further, the surface density of the pressing plate cloth is 130-350g/m². The surface density of the transformer plate cloth can be changed by controlling the parameters of the adhesive and the fiber yarns. Through the research of the inventor, when the areal density of the laminated board cloth is controlled to be within the range, the bulletproof and stab-resistant effect of the bulletproof and stab-resistant chip can be remarkably enhanced.

Further, the fiber filaments constituting the non-woven fabric are selected from one or more of high-performance polyethylene fibers, aramid fibers and polyarylate fibers. When the non-woven fabric is manufactured specifically, the filament linear density of the fiber is 1.25-1.5dtex, and the mechanical property strength of the fiber is more than or equal to 22 cN/dtex.

The invention selects the specific adhesive to be uniformly combined with the fiber, so that the impact energy of the warhead can be diffused to the periphery of the fiber, the absorption of energy is facilitated, and the aim of preventing the warhead from proceeding is fulfilled. Compared with the traditional bulletproof and stab-resistant material, the bulletproof and stab-resistant material is a single material, and is not laminated with bulletproof and stab-resistant functional materials, so that the protective performance and the comfort of bulletproof and stab-resistant functional clothes are obviously improved.

Further, in order to enhance the bulletproof and stab-resistant effects, when the non-woven fabric is produced by dipping the fiber yarns, the fiber yarns are controlled to account for 70-85% of the non-woven fabric by mass, and the adhesive accounts for 15-30% of the non-woven fabric by mass. The laid fabric manufactured according to the proportion can achieve the effects of bullet resistance and stab resistance, the bending length of the subsequent pressboard fabric is 9-20 cm, and the comfort of the bullet-proof and stab-resistant functional clothing is obviously improved.

The implementation of the invention at least comprises the following advantages:

the bulletproof stab-resistant functional garment is excellent in performance, small in weight, high in comfort level and capable of obviously improving the comfort level and flexibility of users, and the bending length of the bulletproof stab-resistant functional garment is as low as 9-20 cm.
