Description

Technical Field

[0001] This utility model relates to the field of fire protection equipment technology, and more specifically, to a heat-insulating protective fabric structure and protective clothing. Background Technology

[0002] In everyday fire scenarios, the main factors endangering personal safety include flames, dense smoke, high-temperature steam, and heat radiation. Among these, the factors causing the most injuries are high-temperature heat radiation and steam burns. In daily fire safety education, we often hear about methods such as wetting clothes and blankets with water for escape. However, since ordinary organic fiber products such as clothing and blankets are not flame-retardant, the risk of the clothing melting and dripping onto the skin after the water in the clothes has completely evaporated under the high temperature of the fire remains. Existing fabrics for high-temperature protection are mostly special fiber fabrics made of expensive new functional materials. However, the cost of such fabrics is very high, and protective clothing made of these fabrics is usually only worn by firefighters during rescue operations. Therefore, there is an urgent need for a lower-cost civilian heat insulation protection solution to resist the impact of flames and heat waves during fires, increasing the chances of escape and rescue. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide a heat-insulating and protective fabric structure, and to provide a protective garment made based on the above-mentioned defects of the prior art.

[0004] The technical solution adopted by this utility model to solve its technical problem is:

[0005] A heat-insulating and protective fabric structure is constructed, comprising a base fabric, wherein a first heat-insulating layer is disposed on the upper surface of the base fabric, the first heat-insulating layer has a high specific surface area, and multiple pores or gaps are dispersedly disposed within the first heat-insulating layer, wherein a modified water-based fire extinguishing agent is disposed within the pores, and the inner wall of the gaps is adhered with a modified water-based fire extinguishing agent.

[0006] The heat-insulating protective fabric structure of this utility model includes a second heat-insulating layer disposed on the lower surface of the fabric. The second heat-insulating layer has a high specific surface area and multiple pores or gaps are dispersedly disposed within the second heat-insulating layer.

[0010] The heat-insulating protective fabric structure of this utility model includes a second heat-insulating layer comprising multiple second microfiber fibers, the gaps in the second heat-insulating layer being the gaps between adjacent second microfiber fibers, and the modified water-based fire extinguishing agent adhering to the outer surface of the second microfiber fibers.

[0012] The beneficial effects of this utility model are as follows: By applying the fabric structure of this application, the substrate made of high specific surface area material provides a large dispersion space and heat insulation area, which improves the heat insulation effect and provides sufficient adhesion space for modified water-based fire extinguishing agents.

[0019] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, a clear and complete description will be provided below in conjunction with the technical solutions in the embodiments of this utility model. Obviously, the described embodiments are some, but not all, of the embodiments of this utility model. Based on the embodiments of this invention, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0020] The preferred embodiment of this utility model has a heat-insulating protective fabric structure, such as... Figure 1 As shown, see also Figures 2-5 The material includes a fabric 1, on the upper surface of the fabric 1 is provided a first heat insulation layer 2, the first heat insulation layer 2 and the second heat insulation layer 3 have a high specific surface area, and the first heat insulation layer 2 is provided with a plurality of pores or gaps, the pores are provided with modified water-based fire extinguishing agent 4, and the inner wall of the gap is attached with modified water-based fire extinguishing agent 4.

[0021] The fabric structure of this application, using a substrate made of high specific surface area material, provides a large dispersion space and heat insulation area, improving the heat insulation effect and providing sufficient adhesion space for modified water-based fire extinguishing agents. The special chemical chain structure in the modified water-based fire extinguishing agent can be rapidly transferred (solid transfer) from one end to the hydrophilic end. After the water molecules at the hydrophilic end absorb a large amount of heat, they are transformed into water vapor and carry away the heat, thus achieving the purpose of heat insulation.

[0022] Preferably, a second heat insulation layer 3 is provided on the lower surface of the fabric 1. The second heat insulation layer 3 also has a high specific surface area. Multiple pores or gaps are dispersed inside the second heat insulation layer 3. Modified water-based fire extinguishing agent 4 is provided in the pores, and modified water-based fire extinguishing agent 4 is attached to the inner wall of the gaps. The use of fabric combined with a double-sided heat insulation layer structure can effectively improve the protective effect. The manufacturing process is simple, the cost of the fabric can be kept low, and it is suitable for promotion and popularization.

[0023] like Figure 2As shown, a preferred embodiment may be: a first insulation layer comprising multiple first microfiber fibers, the gaps between the first insulation layer being the gaps between adjacent first microfiber fibers, and a modified water-based fire extinguishing agent adhering to the outer surface of the first microfiber fibers; a second insulation layer comprising multiple second microfiber fibers, the gaps between the second insulation layer being the gaps between adjacent second microfiber fibers, and a modified water-based fire extinguishing agent adhering to the outer surface of the second microfiber fibers;

[0024] Preferably, the greige fabric is made using warp knitting technology, which makes it more resistant to tearing and deformation; the microfiber is made of pure polyester, which has a better feel.

[0025] The process of producing high-efficiency heat insulation fabric using currently preferred materials is as follows: First, double-sided warp-knitted polyester coral fleece is woven, and then a specially formulated quantitative modified water-based fire extinguishing agent is sprayed / impregnated into the fleece using a suitable spraying / immersion device or equivalent device to obtain a low-cost and high-performance flame-retardant heat insulation fabric.

[0026] like Figure 4 and Figure 5 As shown, Figure 4 This is a schematic diagram of the active chemical substances that play a role in modified water-based fire extinguishing agents. There are hydrophilic and hydrophobic groups at both ends of the chemical structure chain, and the chemical bonds in the chemical structure chain provide a fast channel for heat transfer. Figure 5 This diagram illustrates the presence of this active substance in a large number of fire extinguishing agents / fabric examples. All hydrophilic ends aggregate and connect with larger water molecules. Heat is captured by hydrophobic groups and rapidly transferred to water molecules via chemical structural chains. Water molecules quickly absorb heat and convert it into water vapor, thus carrying away the heat.

[0027] Compared with existing technologies, this application has the following advantages:

[0028] 1. Excellent thermal insulation performance: In a formula of double-sided polyester coral fleece + modified water-based fire extinguishing agent, this flame-retardant and heat-insulating fabric can achieve more than twice the national standard requirement for the thermal insulation capacity of firefighter protective clothing; (The test standard is "XF 10-2014 Firefighter Firefighting Protective Clothing", the test item is 6.1 Overall thermal protection performance, and the TPP standard value requirement for firefighter protective clothing is 28cal / cm²). 2 The TPP test value of this formula fabric can reach >60cal / cm². 2 );

[0029] 2. Long protection time: In the double-sided polyester coral fleece + modified water-based fire extinguishing agent formula, the fabric can maintain a relatively long protection time in the 260℃ high temperature thermal stability test, which is enough to allow people to escape to a relatively safe space. Moreover, the actual protection time will be extended as the fire temperature decreases, providing a longer protection time.

[0030] 3. Lower cost: Compared with existing flame-retardant and heat-insulating fabrics made of special fibers such as aramid, PBI, and PBO, its cost is significantly lower (double-sided polyester coral fleece + modified water-based fire extinguishing agent formula fabric, its unit cost is significantly lower than that of firefighters' fire extinguishing protective clothing), making it suitable for widespread application in the field of civil fire protection.

[0031] It should be noted that:

[0032] 1. High specific surface area substrate: In addition to using microfiber double-sided fleece, there are many other solutions to make high specific surface area heat insulation substrate: ① Single-sided fleece (the fleece is a high specific surface area layer, facing outwards; the substrate is facing inwards) ② Various chemical fiber fleece, cotton fabric; ③ Porous materials made by foaming process, etc.

[0033] 2. Heat insulation agents: In addition to using modified water-based fire extinguishing agents, there are many other ways to produce high-performance heat insulation agents: ① High enthalpy phase change materials encapsulated by microencapsulation technology as a heat absorption solution; ② Materials with low boiling point temperature and fast evaporation rate, etc.

[0034] like Figure 3 As shown, another preferred embodiment may be adopted: the first heat insulation layer includes a first porous frame, and the pores of the first heat insulation layer are the holes on the first porous frame; the second heat insulation layer includes a second porous frame, and the pores of the second heat insulation layer are the holes on the second porous frame.

[0035] A porous framework (such as honeycomb pores, the distribution of which can be customized) serves as a carrier made of a high specific surface area material. The black dots on the framework represent heat-insulating agents dispersed within it, forming a unified whole that becomes the material used to manufacture fire-resistant fabrics. When heat is transferred to the surface of this material, it is captured by a large amount of heat-insulating agent through the high specific surface area material, thus being absorbed or reflected.

[0036] It is understandable that the first insulation layer can also be made of a velvet structure and the second insulation layer can be made of a honeycomb structure, or the first insulation layer can be made of a honeycomb structure and the second insulation layer can be made of a velvet structure. Both of these variations are also within the scope of protection of this application.

[0037] A protective suit, wherein the protective suit includes the heat-insulating protective fabric structure as described above; it should be noted that it is not limited to protective suits, but also includes other clothes, hats, scarves, etc. made using this fabric structure, which are all within the scope of protection of this application.

[0038] It should be understood that those skilled in the art can make improvements or modifications based on the above description, and all such improvements and modifications should fall within the protection scope of the appended claims.
