Description

Technical Field

[0001] The utility model relates to the technical field of textile fabrics, in particular to a waterproof and heat-insulating fabric. Background Art

[0002] At present, as a key protective equipment for firefighters during mission execution, fire-fighting suits already have certain fire-proof functions. However, in complex and changeable rescue environments, firefighters still face multiple challenges, such as sweat discharge and sewage splashing, which pose higher requirements for the sweat-venting and waterproof properties of fire-fighting suits.

[0003] Traditional fire-fighting suits are mostly made of flame-retardant materials to achieve basic fire-proof functions. To improve the waterproof performance, some fire-fighting suits are coated with waterproof membranes on the outer layer. However, these measures often sacrifice the breathability and sweat-venting properties of the fabric, resulting in firefighters feeling stuffy and uncomfortable after long-term operations.

[0004] Existing fire-fighting suits are difficult to achieve a balance in waterproof, heat-insulating and sweat-venting properties, and lack effective antibacterial functions, thus unable to comprehensively ensure the safety and health of firefighters. Summary of the Utility Model

Detailed description of the specific embodiment

[0031] The present utility model will be further described in detail below with reference to the accompanying drawings. The same components are denoted by the same reference numerals. It should be noted that the terms "front", "rear", "left", "right", "upper", "lower", "bottom surface" and "top surface" used in the following description refer to the directions in the drawings, and the terms "inner" and "outer" refer to the directions towards or away from the geometric center of a specific component, respectively.

[0032] The present utility model discloses a waterproof and heat-insulating fabric, as Figures 1 to 3 shown, which includes an aramid material layer 1. The surface of the aramid material layer 1 adopts plasma etching technology to increase its surface roughness and hydrophilicity. An adhesive layer 2 is provided outside the aramid material layer 1. An adhesive 9 is provided on the surface where the adhesive layer 2 is connected to the aramid material layer 1 and the spunlace felt layer 5. The adhesive 9 is used to bond the adhesive layer 2 to the aramid material layer 1 and the spunlace felt layer 5. The adhesive 9 adopts an acrylate adhesive 9, and the acrylate adhesive 9 has good bonding performance and weather resistance, which can ensure the long-term stable bonding between the adhesive layer 2 and the aramid material layer 1 and the spunlace felt layer 5. A plurality of accommodation cavities 3 are provided on the adhesive layer 2, and the plurality of accommodation cavities 3 are evenly distributed. The accommodation cavities 3 are filled with ceramic microbeads 4. The uniform distribution of the ceramic microbeads 4 can ensure effective heat insulation inside the fabric and improve the heat insulation performance. A spunlace felt layer 5 is provided outside the adhesive layer 2. A PTFE film 6 is coated on the surface of the spunlace felt layer 5. Due to its one-way waterproof property, the PTFE film 6 significantly improves the waterproof performance of the fabric. At the same time, an ultrafine fiber mesh 7 is added between the spunlace felt layer 5 and the PTFE film 6. The ultrafine fiber mesh 7 is tightly combined with the PTFE film 6 to form a composite waterproof layer, further consolidating the waterproof effect. The PTFE film can be replaced with other polymer film materials with similar waterproof performance, such as polyvinylidene fluoride (PVDF) film or polyvinyl alcohol (PVA) film, etc. While maintaining the waterproof effect, these replacement materials can adjust the cost, flexibility and weather resistance of the fabric according to specific application scenarios. A porous structure 8 is provided on the ultrafine fiber mesh 7. These evenly distributed porous structures 8 not only help the fabric absorb moisture but also quickly discharge sweat, thus greatly improving the wearing comfort.

[0033] An anti-ultraviolet layer 10 is provided outside the spunlace felt layer 5. This layer is made of a coating material containing titanium dioxide, enabling the fabric to add a new anti-ultraviolet function while maintaining the original waterproof and heat-insulating properties. Titanium dioxide provides additional protection for the wearer with its excellent ultraviolet shielding ability. Sealing edges 11 are provided at the edges of the aramid material layer 1, the viscose layer 2, and the spunlace felt layer 5. The aramid material layer 1, the viscose layer 2, and the spunlace felt layer 5 are edge-sealed through the sealing edges 11. Through this edge-sealing treatment of the sealing edges 11, a strong defense line is also formed at the edge part of the fabric, effectively preventing moisture and heat from penetrating through the edges, thereby comprehensively improving the overall waterproof and heat-insulating effect of the fabric.

[0034] Working principle: A waterproof and heat-insulating fabric designed by the utility model mainly consists of three parts: the aramid material layer 1, the viscose layer 2, and the spunlace felt layer 5. The aramid material layer 1, the viscose layer 2, and the spunlace felt layer 5 are arranged in sequence from the inside to the outside. The aramid material layer 1 and the spunlace felt layer 5 are connected to each other through the adhesive 9 with the viscose layer 2. By coating a PTFE film 6 on the surface of the spunlace felt layer 5, a one-way waterproof function is realized. By arranging uniformly distributed ceramic microspheres 4 in the viscose layer 2, the heat-insulating function of the fabric is realized. At the same time, by using the ultrafine fiber mesh 7 arranged between the spunlace felt layer 5 and the PTFE film 6, a composite waterproof layer is formed, further improving the waterproof ability of the fabric. At the same time, by using the porous structure 8 of the ultrafine fiber mesh 7, the moisture absorption and sweat discharge ability of the fabric can be enhanced without affecting the waterproof performance. In summary, a waterproof and heat-insulating fabric designed by the utility model realizes the performance improvement of the fire-fighting suit fabric in multiple aspects such as fire prevention, waterproofing, heat insulation, and antibacterial by combining multiple layers of structures such as aramid materials, the viscose layer 2, the spunlace felt layer 5, and the PTFE film.

[0035] The above are all the preferred embodiments of this application. The protection scope of this application is not limited by this. Therefore, all equivalent changes made according to the structure, shape, and principle of this application should be covered within the protection scope of this application.
