Description

A kind of elastic fireproof composite material

Technical field

The utility model is related to a kind of composite material, especially a kind of elastic fireproof composite material.

Background technology

Fire safety evaluating is the huge challenge faced in people's life, however the common fabric that people are worn does not have resistance mostly Fire function.Encounter open fire when wearing to be easy to be ignited, to damage the security of the lives and property of people.Currently, specially Metal aluminum foil is mostly used in the fire-fighting fire-proof clothes of industry greatly and carries out fire partition outside common fabric as composite layer, is reduced to people Body injures.Or the fabric prepared using the fiber for only having flame retarding function is as first of barrier of fireproof.Have at present The fiber of fire-proof function is mostly mineral fibre and metallic fiber, but because fiber stiffness is big, initial modulus is high, thus formed Fabric is nonelastic, and feel is poor, and density is larger, limits the movement range of fire fighter so that its clothes load aggravates, consumer Power.By metal aluminum foil is compound or prepared by metallic fiber, inorganic salt mineral fiber fireproof facing material because its weight is big, rigidity Greatly, not fit so that its comfort level worn substantially reduces.In scene of fire, clothes prepared by existing fireproof facing material are easy Sultry environment is formed, fire fighter's serious dehydration, threat to life safety are caused.For this purpose, how to research and develop a with elastic, light Thin, air-moisture-permeable fireproof facing material seems more significant.

Utility model content

The purpose of this utility model is to provide a kind of elastic fireproof composite material, close existing for existing fireproof facing material to solve The problems such as spending big, airtight, poor flexibility, while enough improving the fire protecting performance of fabric, meet snugness of fit.

The utility model provides a kind of elastic fireproof composite material, including base cloth layer, fireprotection layer and soak layer, the base Layer of cloth is compound in the side of the soak layer, and the fireprotection layer is compound in the other side of the soak layer, and the base cloth layer is by passing through Yarn and weft yarns form, and the warp thread includes elastic inner core and the first outer yarn and second for being coated on outside the elastic inner core Outer yarn, the first outer yarn are coated on opposite twist direction outside the elastic inner core with the described second outer yarn, the first outer yarn For polyamide fibre complex yarn, the second outer yarn is polyethylene fibre, and the weft yarn is polyester-cotton blend complex yarn, the fireprotection layer distance The soak layer includes interior fireprotection layer and outer fireprotection layer successively from the near to the distant.

Preferably, the elastic inner core is spandex thread.

Preferably, the described first outer yarn（5）For polyamide fibre complex yarn, including chinlon filament inner core（7）Be coated on brocade Synthetic fibre long filament inner core（7）The polyamide fibre aerophane in outside, the polyamide fibre aerophane is by least three groups of polyamide fibre filament fibers（8）Structure arranged side by side At；The second outer yarn（6）For polyethylene fibre.

Preferably, at least one group of the polyamide fibre filament fiber is antibacterial nylon silk.

Preferably, the weft yarn include polyester-cotton blend inner core, the intermediate yarn layer that is coated on outside the polyester-cotton blend inner core and cladding Outer yarn layer outside the intermediate yarn layer, the polyester-cotton blend inner core is that polyester fiber is mutually entwined with cotton fiber, in described Between yarn layer be cotton yarn layer, the outer yarn layer be copper ammonia fiber yarn layer.

Preferably, the interior fireprotection layer is polypropylene fiber layer, and the outer fireprotection layer is aramid fiber layer.

Preferably, the soak layer is bamboo fiber layer.

Compared with prior art, the beneficial effects of the utility model are：

Warp thread is spandex filament in Base fabric, has good elasticity, can ensure the fitness of fabric, reduction pair The limitation of motion amplitude.Cotton fiber regain in base fabric in the chinlon filament and weft yarn of warp thread is larger, can be by fire fighter The sweat of generation adsorbs rapidly so that fire fighter keeps body dry and comfortable in heated situation, and it is hot caused by body to reduce sweat Wet and discomfort.The polyethylene fibre of the second clad of base fabric warp thread has good heat resistance, fabric when ensureing heated It does not melt, does not scald skin.Have unidirectional moisture conducting function with the soak layer of composite for base fabric, it can be by sweat and steam rapidly from base Layer of cloth exports, and persistently maintains the dry and comfortable comfortable of base cloth layer.For existing pure cotton composition metal aluminium foil fireproof facing material, this The increased soak layer of utility model largely avoids sweat can form high heat and humidity environment in fireproof garment, and it is wet right to reduce heat The human injury of fire fighter and muscle power are overdrawed.In fireprotection layer, it is respectively adopted polypropylene fibre fabric and in kevlar fabric formed Outer fireprotection layer forms enhanced fire-proofing structure, improves fire safety performance.It is fine compared to existing metal aluminum foil and minerals The fireprotection layer formed is tieed up, the inside and outside fireprotection layer using polypropylene fibre fabric and kevlar fabric formation in the utility model increases The fitness of fireproof garment, alleviates fireproof garment weight, and the movement that ensure that fire fighter freely, protects fire fighter personal Safety.Meanwhile the inside and outside fireprotection layer of the polypropylene fibre fabric and kevlar fabric formation in the utility model has good resist Deformation behavior, the fireproof garment for overcoming metal aluminum foil and mineral fibres preparation is not foldable, and Large Amplitude Motion position is easily broken Defect increases the service life of fireproof clothes.
