Referring to fig. 1 and 2, an embodiment of the present invention provides an outer fabric of a high thermal protection fire-fighting clothing, which mainly includes: comprises a surface layer fabric 10 formed by interweaving surface layer warp yarns 11 and surface layer weft yarns 12 and an inner layer fabric 20 formed by interweaving inner layer warp yarns 21 and inner layer weft yarns 22; the surface layer fabric 10 and the lining layer fabric 20 are bound through a plurality of warp binding yarns 13 and a plurality of weft binding yarns 23, so that an air layer is formed at the non-binding position of the surface layer fabric 10 and the lining layer fabric 20;
wherein, the thermal shrinkage rate and the thermal conductivity of the surface layer warp yarns 11 and the surface layer weft yarns 12 are higher than those of the back layer warp yarns 21 and the back layer weft yarns 22; the surface layer warp yarns 11, the surface layer weft yarns 12, the warp-wise binder yarns 13 and the weft-wise binder yarns 23 are yarns made of one or more of aramid fibers, modacrylic fibers, flame-retardant viscose fibers, basalt fibers and organic conductive fibers, the inner layer warp yarns 21 and the inner layer weft yarns 22 are yarns made of 70-85% of low-thermal-conductivity fibers, 13-28% of aramid fibers and 2% of organic conductive fibers in percentage by mass, and the low-thermal-conductivity fibers are one or more of polyimide fibers, wool fibers and aramid fibers.
In the embodiment, the outer fabric of the high-heat protection fire-fighting clothing provided by the embodiment of the invention is of a double-layer structure and mainly comprises a surface fabric and an inner fabric. The surface fabric is formed by interweaving surface warp yarns and surface weft yarns, the lining fabric is formed by interweaving lining warp yarns and lining weft yarns, and the surface fabric and the lining fabric can be plain, twill or variable weave.
Further, the surface layer fabric and the lining fabric are bound by a plurality of warp binder yarns and a plurality of weft binder yarns, so that the surface layer fabric and the lining fabric form a plurality of air layers at non-binding positions. Because the thermal shrinkage rate and the thermal conductivity of the surface layer warp yarns and the surface layer weft yarns are higher than those of the inner layer warp yarns and the inner layer weft yarns, the outer layer fabric shrinks to form air bulges when being heated due to the inconsistent thermal shrinkage rate of the surface layer warp yarns and the inner layer weft yarns, and the structure can effectively block heat and improve the heat insulation performance of the outer layer fabric.
In addition, the existing outer-layer fabric usually adopts imported fibers, although a certain heat insulation effect can be achieved, the imported fibers are expensive and high in production cost, and meanwhile, the fabric is heavy in gram weight and is difficult to lighten. In the embodiment, the outer layer fabric preferably adopts a material with lower thermal conductivity to achieve the purpose of high thermal insulation performance, the proportion of the used material in the gram weight of the total fabric is fully considered when the low thermal conductivity of the material is utilized, the size of a generated air layer is also considered, and the surface layer of the outer layer fabric cannot crack due to long-time flame contact after the low thermal conductivity material is adopted, so that the materials are reasonably selected, the synergistic effect among fibers is realized, the production cost can be reduced and the weight is reduced when the thermal insulation performance of the outer layer fabric is improved, and the outer layer fabric can meet the actual use requirement.
Therefore, in this embodiment, the surface layer warp yarns, the surface layer weft yarns, the warp binder yarns and the weft binder yarns are yarns made of one or more of aramid fibers, modacrylic fibers, flame retardant viscose fibers, basalt fibers and organic conductive fibers, and the lining warp yarns and the lining weft yarns are yarns made of 70-85% by mass of low thermal conductivity fibers, 13-28% by mass of aramid fibers and 2% by mass of organic conductive fibers, wherein the low thermal conductivity fibers are one or more of polyimide fibers, wool fibers and aramid fibers. The aramid fibers in the surface layer warp yarns, the surface layer weft yarns, the warp binder yarns and the weft binder yarns are preferably aramid 1313 fibers and aramid 1414 fibers, and the aramid fibers in the lining warp yarns and the lining weft yarns are preferably aramid 1313 fibers.
Therefore, the outer-layer fabric realizes higher heat-insulating performance, effectively lightens the whole weight of the fabric, reduces the production cost and is very suitable for manufacturing high-heat protection fire-fighting clothing by a plurality of air layers formed at the non-binding positions of the surface-layer fabric and the inner-layer fabric and the materials prepared from the components and the proportion.

Preferably, the surface fabric 10 is provided with a continuous lattice structure, the longitudinal stripes of the lattice structure are formed by two surface layer warp yarns 11 interwoven by the surface layer weft yarns 12, and the transverse stripes of the lattice structure are formed by two surface layer weft yarns 12 interwoven by the surface layer warp yarns 11; the warp binder yarns 13 bind the surface layer fabric 10 and the inner layer fabric 20 at the wales, and the weft binder yarns 23 bind the surface layer fabric 10 and the inner layer fabric 20 at the wales.
Specifically, a continuous lattice structure is further arranged on the surface layer fabric, and the lattice structure is also called as a two-centimeter lattice, so that the surface layer fabric has special functions of tearing resistance, wear resistance and the like. Even two adjacent structure points of surface fabric longitude and latitude are the same, the same department of structure point will play check like this, when tearing the surface fabric, plays check department and is difficult for tearing to have anti-tear function.

In this embodiment, the size of the lattice structure is preferably set to 0.5 × 0.5cm, and the effect of preventing tearing is excellent.
Further, when the surface layer fabric and the inner layer fabric are bound by a plurality of warp binder yarns and a plurality of weft binder yarns, it is preferable that the warp binder yarns bind the surface layer fabric and the inner layer fabric at the vertical stripes of a certain lattice structure and the weft binder yarns bind the surface layer fabric and the inner layer fabric at the horizontal stripes of a certain lattice structure. By the arrangement, warp binder yarns can be fully extruded by two adjacent surface layer warps, and weft binder yarns can be fully extruded by two adjacent surface layer wefts, so that the warp binder yarns or the weft binder yarns are not exposed, the yarns are less exposed on the surface layer, and the problem that the surface of the fabric is uneven due to the fact that the yarns are raised can be avoided.
Preferably, the arrangement of the surface layer warp yarns 11 and the back layer warp yarns 21 is 1.2-1.5: 1, and the arrangement of the surface layer weft yarns 12 and the back layer weft yarns 22 is 1.6-2: 1.

By adopting the arrangement configuration, the weight of the surface layer fabric accounts for 50-58% of the total weight of the whole outer layer fabric, and the weight of the inner layer fabric accounts for 42-50% of the total weight of the whole outer layer fabric.
Preferably, the distance between each adjacent warp-wise binder yarn 13 is 1 to 3cm, and the distance between each adjacent weft-wise binder yarn 23 is 1 to 3 cm.
Specifically, when the surface fabric and the lining fabric are bound by the plurality of warp binder yarns and the plurality of weft binder yarns, a certain distance should be kept between two adjacent warp binder yarns or two adjacent weft binder yarns to sufficiently increase an air layer between the surface fabric and the lining fabric, so that a relatively obvious air bulge can be generated when heat is applied, and the heat insulation performance is increased.
The warp and weft are respectively bound, so that the formed air layer is of a quadrilateral structure, and one warp binder yarn and one weft binder yarn are arranged in each air layer, so that the surface fabric can be prevented from being seriously shrunk, and the structure of the surface fabric is more stable.
