Description

Fire-fighting protective clothing for firemen
Technical Field
The invention belongs to the technical field of textile clothing, and particularly relates to a fire-extinguishing protective garment for a fireman.
Background
The fire-fighting protective clothing for the firefighters is important individual protective equipment for protecting the trunk, the limbs and the head of the firefighters in fire-fighting rescue combat. In order to standardize the performance requirements of the fire-fighting protective clothing for firefighters, the performance standards of the protective clothing are provided in all countries, wherein the fire-fighting protective clothing for the firefighters in the national standard adopts the industrial standard GA10 fire-fighting protective clothing, and the standard four-layer fabric combined structure is specified and comprises an outer layer, a heat insulation layer, a waterproof breathable layer and a comfortable layer. Such thermal protective garments comprising a four-layer laminate composite structure may provide adequate thermal protection, but are relatively heavy. For example, bulkier garments are less stretchable, not only fatiguing the wearer, but also presenting a risk of heat stroke when worn in the hot summer environment. Furthermore, for firefighters, there is often a lot of perspiration during fire protection due to the heat of the environment and the effort they are trying to perform their fire-fighting duties. The perspiration is typically absorbed by the inner layer so that the firefighter can remain dry. The weight of an already relatively heavy garment may increase significantly if a large amount of perspiration is absorbed into the inner layer. In addition, these absorbed perspiration can affect the breathability and thermal comfort of the thermal protective garment. In order to maintain the thermal comfort of the thermal protective garment, the garment assembly must be capable of allowing water vapor, such as that of perspiration, to pass therethrough at an appropriate level, i.e., have good moisture vapor transmission properties.
Therefore, the ideal fire-extinguishing protective clothing for summer is a thermal protective clothing combination which is developed by using the lightest possible combined fabric and has high heat insulation efficiency, so that the weight of the clothing combination is reduced, the operability and the moisture permeability are increased, and the individual safety protection requirement in a high-temperature environment is met.

In the following description, reference is made to the accompanying drawings that describe several embodiments of the application. The following detailed description is not to be taken in a limiting sense, and the scope of embodiments of the present application is defined only by the claims of the issued patent. Spatially relative terms, such as "upper," "lower," "left," "right," "lower," "below," "lower," "above," "upper," and the like, may be used herein to facilitate describing one element or feature's relationship to another element or feature as illustrated in the figures.
Fig. 1 shows a schematic structural view of one implementation of the firefighter fire fighting protective garment of the present invention, as shown in fig. 1, comprising: an outer layer fabric 1 and a comfortable layer fabric 2; the outer-layer fabric 1 is a double-layer weave structure weaving fabric and comprises a fabric surface layer and a fabric inner layer; the thermal protection performance of the combined outer layer fabric and the comfortable layer fabric is more than or equal to 28cal/cm2。
Referring to fig. 2, in the present embodiment, the surface fabric layer 11 and the back fabric layer 12 form an interwoven region 13 and a non-interwoven region in the double-weave-structure woven fabric, and after a predetermined treatment is performed on the surface fabric layer 11 and the back fabric layer 12, protrusions 14 are formed in the non-interwoven region.
In the present embodiment, the surface layer 11 and the back layer 12 of the fabric are subjected to water washing and high temperature setting treatment, and then the protrusions 14 are formed in the non-woven region. Specifically, the warp and weft yarns of the fabric surface layer 11 are elastic yarns, for example, elastic flame-retardant yarns, the flame-retardant yarns may be formed by twisting flame-retardant carbonized yarns and elastic spandex yarns together, the yarn count thickness of the flame-retardant yarns is Ne:50/2-Ne:36/2, and in a specific embodiment, the optimal yarn count thickness of the fabric surface layer 1 is Ne: 40/2.
The warp and weft yarns of the lining layer 12 are inelastic yarns, such as para-aramid yarns with strong rigidity; the yarn count thickness of the inner layer 12 of the fabric is 100D-600D. In a specific embodiment, the optimum yarn count thickness of the inner layer 2 of the fabric is 200D.
In one embodiment of the invention, in the fabric weave circulation, the fabric surface layer 11 and the fabric inner layer 12 are connected by the lower binding yarns according to a certain rule, and the shape of the non-interweaving area of the fabric surface layer 11 and the fabric inner layer 12 is a symmetrical pattern structureThe symmetrical pattern structure includes, for example: circle, rhombus, quadrangle, triangle, pentagon, hexagon, etc., wherein the area of the non-interlacing area is not less than 0.25cm2. As shown in fig. 3, the shape of the non-interlaced region in this embodiment is circular.
In the embodiment, the surface layer 11 of the fabric with the warp and weft yarns as the flame-retardant elastic yarns and the lining layer 12 of the fabric with the warp and weft yarns as the rigid para-aramid yarns are adopted, and the square meter gram weight range of the fabric is 250-350g/cm2The fabric represents an elastic convex double-layer fabric, and the weight of the fabric is greatly reduced by adopting the fabric.
In the present embodiment, since the surface fabric layer 11 is made of elastic yarns, and the inner fabric layer 12 is made of inelastic rigid yarns, so that the yarns of the surface fabric layer 11 shrink, but the yarns of the inner fabric layer 12 do not shrink, the yarns of the inner fabric layer 12 form the protruding structures 14 according to the shape of the non-interlaced region, and the protruding structures 14 form the stable air layer structure 15 in the surface fabric combined structure, air is the best heat insulating material, and thus the heat insulating Performance, i.e. the Thermal Protective Performance (TPP), is good.
In specific application, after the fabric with the double-layer structure is subjected to water washing-high-temperature setting treatment, the yarns of the surface layer 11 of the fabric shrink, and the yarns of the inner layer 12 of the fabric do not shrink, so that the inner layer 12 of the fabric and the surface layer 11 of the fabric form a protruding structure 14 in a non-interweaving area to form an air layer structure 15. Specifically, in order to make the air layer structure 15 of the projection structure 14 effective for preventing the scald/burn due to high temperature, the height of the projection structure 12 is not less than 1mm, although the higher the air layer height of the projection structure 12 is, the better the effect is, and the height is not particularly limited in the present application.
In other embodiments, when the protective clothing using the double-layer fabric is used for high-temperature operation, the protective clothing can be subjected to predetermined treatment by watering, soaking, sprinkling and the like in advance, so that the raised structures 14 are formed in the non-interlaced areas of the surface fabric layer 11 and the inner fabric layer 12, and the air layer structure 15 is formed, and thus the protective clothing can be effectively used for preventing the high-temperature operation from being burnt by high temperature.
In the present embodiment, the comfort layer fabric 2 may be a single-layer fabric or a double-layer fabric. The fabric comprises an outer layer fabric, a single-layer/double-layer tissue comfort layer fabric and a PTFE membrane layer, wherein the outer layer fabric and the single-layer/double-layer tissue comfort layer fabric are arranged in parallel, the PTFE membrane layer can be arranged at a proper position according to actual requirements, for example, the PTFE membrane can be attached to the comfort layer fabric, the invention is not limited to this, and the PTFE membrane can be arranged in other ways according to actual requirements.
When the outer layer fabric 1 in the embodiment is combined with the single-layer structure comfort layer fabric to test the heat insulation performance, the GA10 TPP value of more than 28cal/cm can be satisfied2Specifically, the single layer weave comfort layer fabric may have a unit gram weight of 160 grams per square meter. If the outer layer fabric and the double-layer-structure comfortable layer fabric are combined to test the heat insulation performance, the TPP heat protection performance value is better, because the thickness of the double-layer structure of the fabric with the same gram weight is larger than that of the single-layer structure, and the thickness directly influences the combined heat protection performance TPP value, in the embodiment, the unit gram weight of the double-layer-structure comfortable layer fabric is 160 g/square meter. It should be noted that, in practical application, the fabric of the protective clothing may be designed as the composition of the double-layer outer fabric and the single-layer-weave comfort layer fabric, or as the composition of the double-layer outer fabric and the double-layer-weave comfort layer fabric, which is not limited in this respect.
Next, in this embodiment, a performance comparison test of the protective suit using the double-layer outer fabric, the single-layer/double-layer comfort layer, and the PTFE film layer and the standard four-layer fabric combined structure is performed, and the comparison information is shown in table 1.

And measuring and recording the temperature change condition of the sample along with time by using a copper heat sensor, and converting the temperature change condition into heat energy transmitted through the sample by combining the thermal performance parameters of copper to obtain a heat transfer reaction curve of the heat energy along with the time change. It is composed of a base, a cover and a coverThe actual protective effect of the material fabric in use can be objectively predicted by relating the thermal protection of the fabric to the visual perception of human skin. Therefore, the TPP value is an important data index for evaluating the thermal protection performance of the clothes. Higher values of TPP indicate better thermal protection of the fabric.
According to the range value of the test data, by adopting the two-layer fabric combination scheme of the embodiment, the TPP thermal protection performance can meet the requirement of thermal protection performance in the standard GA10 (not less than 28 cal/cm)2). Moreover, the weight of the protective clothing can be greatly reduced by adopting the two layers of fabrics, and the comfort of the protective clothing is improved.
As shown in fig. 4, the structural schematic diagram of another implementation of the fire fighter fire fighting protective clothing of the invention is a structural schematic diagram, and as shown in the figure, the protective clothing comprises: an outer layer fabric 3 and a comfortable layer fabric 4; the outer-layer fabric 3 is a double-layer weave structure weaving fabric and comprises a fabric surface layer 31 and a fabric inner layer 32; the thermal protection performance of the combined outer layer fabric and the comfortable layer fabric is more than or equal to 28cal/cm2。
Referring to fig. 5, in the present embodiment, the surface fabric layer 31 and the inner fabric layer 32 form an interwoven region and a non-interwoven region in the double-weave-structure woven fabric, and after a predetermined treatment is performed on the surface fabric layer 31 and the inner fabric layer 32, a protrusion 33 is formed in the non-interwoven region.
In the embodiment, the warp and weft yarns of the surface layer 31 of the fabric are aramid IIIA yarns, and the IIIA yarns include 93% of meta-aramid fiber, 5% of para-aramid fiber and 2% of antistatic fiber; the warp and weft yarns of the inner layer 32 of the fabric are para-aramid yarns with strong rigidity.
The aramid IIIA yarn of the surface layer 31 of the fabric has a larger shrinkage performance when encountering flame or high temperature, while the para-aramid yarn of the inner layer 32 of the fabric does not shrink or shrinks less when encountering fire, and at this time, the yarns of the inner layer 32 of the fabric form a protruding structure 33 according to the shape of a non-interlaced area surface, specifically, as the protruding structure 33 shown in fig. 4 in the embodiment, the protrusion forms a stable air layer structure 34 in the fabric combined structure, and air is an optimal heat insulating material, so that the heat insulating performance is good, that is, the Thermal Protection Performance (TPP) is good.
In the present embodiment, when the double-layer fabric is used as an outer layer of the protective clothing, the fabric surface layer 31 contracts in the warp and weft directions, and the fabric inner layer 32 does not contract, so that the raised structures 33 are formed, and the raised structures and the fabric surface layer 31 form the air layer structure 33. Specifically, the height of the protrusion is 1mm at the lowest, and generally, the higher the height of the protrusion is, the better the protection effect is. When the fabric is used at high temperature, the convex structure 33 can be automatically formed, so that the fabric is a thermally-induced convex double-layer fabric; in the embodiment, the fabric is formed by the surface layer 31 of the fabric with the warp and weft yarns as the aramid IIIA yarns and the inner layer 32 of the fabric with the warp and weft yarns as the rigid para-aramid yarns, and the square meter grammage range of the fabric is 200-250 g/square meter.

In this embodiment, when the thermally raised double-layer fabric is used as the outer fabric, the fabric of the protective garment is not required to be raised and shaped in advance, and the thermally raised double-layer fabric and the double-layer tissue comfortable fabric are directly combined to be designed into the fabric of the protective garment, so that the shape of the protective garment is designed. When the protective clothing using the thermotropic convex double-layer fabric as the outer-layer fabric is in the protection process, if open fire or high temperature is met, the surface fabric surface layer of the outer-layer fabric of the protective clothing can contract in the warp and weft directions by itself, and forms a protrusion with the inner layer of the surface fabric of the outer-layer fabric to form an air layer for heat insulation protection.
In this embodiment, the protective performance of the protective suit with the double-layer fabric combined structure of this embodiment is compared with that of the standard four-layer fabric combined structure, and the comparison information is shown in table 3.
