Detailed Implementation

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Most existing fire suits only have high-temperature resistance, which can easily cause burns to firefighters' skin and are not very comfortable when worn for a long time at a fire scene. The following describes some embodiments of the present invention with fire suits that have flame-retardant and cooling functions.

[0023] Example 1:

[0024] To ensure the effectiveness of fire suits, combined with Figures 1-4 As shown, a fire-fighting suit with flame-retardant and cooling functions is proposed, which is mainly composed of a body 1 and trousers 2. The materials of the body 1 and trousers 2 are both composed of an outer layer 101, a waterproof and breathable layer 102, a heat insulation layer 103, and a comfort layer 104.

[0025] To improve the flame-retardant and heat-insulating effect of the fire suit, the waterproof and breathable layer 102 is composed of an outer layer 1021, a middle layer 1022, and an inner layer 1023 made of polytetrafluoroethylene and polyethylene composite membrane material arranged sequentially. The outer layer 1021, middle layer 1022, and inner layer 1023 are perforated with gradient-distributed perforations 1024. The pore size of the outer layer 1021 is 0.1-0.5μm, the pore size of the middle layer 1022 is 0.5-2μm, and the pore size of the inner layer 1023 is 2-5μm. The middle layer 1022 has heat-sensitive fibers 1025 that automatically adjust porosity at high temperatures. The middle layer 1022 also has embedded paraffin microcapsules 1026 that enhance cooling effect and can absorb and store a large amount of latent heat. The heat insulation layer 103 is composed of silica aerogel and aramid fibers, using a 3D mesh needle. The fabric structure increases the air layer thickness to 5-8mm, improving the thermal insulation effect. By using a composite membrane of polytetrafluoroethylene and polyethylene, the perforations 1024 achieve a gradient pore size distribution of 0.5-5μm, greatly improving air permeability. Paraffin microcapsules 1026 are embedded in the middle layer 1022, which can absorb and store a large amount of latent heat, further reducing the temperature of the inner layer 1023. The heat-sensitive fiber 1025 and the perforations 1024 form a synergistic effect. When the temperature rises, the phase change material absorbs heat and expands, automatically adjusting the opening of the perforations 1024 to achieve dynamic air permeability regulation, ensuring the cooling effect of the fire suit. The thermal insulation layer 103 is composed of silica aerogel and aramid fiber composite, which significantly reduces the thermal conductivity. It adopts a 3D mesh knitted structure, increasing the air layer thickness to 5-8mm, improving the overall thermal insulation effect.

[0026] Example 2:

[0027] Based on Example 1, the technical solution proposed in Example 1 is used to solve the problem that most fire suits in the prior art only have the effect of high temperature resistance, which can easily cause firefighters to suffer skin burns and have low comfort when used in a fire scene for a long time. However, when fire suits are used in a fire environment, their comfort is related to the efficiency of firefighters, so they need to be further improved.

[0028] To improve the comfort of firefighters, combined with Figures 1-4 As shown, the comfort layer 104 is made of modified polyester and cotton blend, with sponge-like pores distributed on its surface to mimic the microstructure of human tissue, improving fit and enhancing the wearing effect for firefighters. Abrasion-resistant layers 3 are provided at the joints of the garment body 1 and trousers 2. Multiple reflective strips 4 are installed on the surface of the garment body 1 and trousers 2, making firefighters more visible in a fire environment and easier for trapped personnel to spot. The outer and inner sides of the garment body 1 are connected by Velcro 5. Breathable mesh fabric 6 is provided under the armpits of the garment body 1 to further improve the breathability of the fire suit and enhance the comfort of firefighters.

[0029] The outer layer 101 is a flame-retardant viscose blended woven fabric with micron-sized pores on its surface. The formation of micron-sized pores on the surface of the flame-retardant fabric maintains its flame retardancy while enhancing breathability and reducing its thermal conductivity. It also features a nano-titanium dioxide photocatalytic coating that can decompose oil stains and combustion residues, maintaining surface cleanliness.

[0030] It should be noted that the terms “comprising,” “including,” or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such process, method, article, or apparatus.

[0031] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
