Description

Technical Field

[0001] The utility model relates to the technical field of fire fighting appliances, in particular to an ice - resistant fire fighting suit. Background Technique

[0002] As one of the important equipment for protecting the lives of firefighters who rush to the front line of rescue and disaster relief, the fire fighting suit is an essential personal protective equipment at the fire scene.

[0003] Firefighters have to come into frequent contact with water during the execution of tasks. The entire fire - fighting process is very long. Firefighters not only have to extinguish the fire, but also continuously spray water on the fire scene until there is no possibility of re - ignition. In a low - temperature environment below 0°C, water will freeze on the surface of the fire fighting suit, resulting in an increase in the wearer's load, a decrease in activity flexibility, a significant reduction in work efficiency, and even danger to the wearer. At the same time, during the high - intensity work process, firefighters will sweat a lot, and the sweat will be absorbed by the fire fighting suit, causing the humidity inside it to be too high, forming an uncomfortable wet - cold state. After the existing fire fighting suits are in contact with water for a long time in a cold environment, serious icing will occur on their surfaces. The frozen fire fighting suit becomes hard, which will greatly reduce the work efficiency of firefighters. After the existing fire fighting suits are worn for a long time, a wet - cold state is likely to form inside, greatly reducing the wearing comfort.

[0004] Therefore, the utility model provides an ice - resistant fire fighting suit to solve the above problems. Content of the Utility Model

[0005] In view of this, the purpose of the utility model is to provide an ice - resistant fire fighting suit to solve the problem that various existing fire fighting suits will have serious icing phenomena after being in contact with water for a long time in a low - temperature environment below 0°C, which will greatly reduce the work efficiency of firefighters.

[0006] Based on the above purpose, the utility model provides an ice - resistant fire fighting suit, which includes an upper garment and trousers. From the outside to the inside, the upper garment and trousers both include an ice - resistant flame - retardant layer, a waterproof, moisture - permeable and heat - insulating layer, and a comfort layer that are stacked in sequence. An ice - resistant material coating is provided on the side of the ice - resistant flame - retardant layer away from the human body surface. The waterproof, moisture - permeable and heat - insulating layer includes a heat - insulating aramid felt and waterproof, moisture - permeable membranes adhered to opposite sides of the heat - insulating aramid felt. An imitation brim - structured waterproof strip and an ice - resistant coating stripe are provided on both the upper garment and the trousers. The imitation brim - structured waterproof strip is used to prevent external water from quickly wetting the lower hem of the upper garment and from entering the fire boots, and the ice - resistant coating stripe is used to delay the icing time on the surface of the fire fighting suit and improve the ice - removal efficiency on the surface of the fire fighting suit.

[0026] Such as Figures 1 to 6As shown in the figure, a de-icing fire-fighting suit includes a coat 1 and trousers 2. The coat 1 and the trousers 2 both sequentially include a de-icing and flame-retardant layer 3, a waterproof, moisture-permeable and heat-insulating layer 4, and a comfort layer 5 which are stacked from outside to inside. A de-icing material coating is provided on the side of the de-icing and flame-retardant layer 3 away from the human body surface. The waterproof, moisture-permeable and heat-insulating layer 4 includes a heat-insulating aramid felt 6 and waterproof and moisture-permeable membranes 7 adhered to opposite sides of the heat-insulating aramid felt 6. The coat 1 and the trousers 2 are both provided with a waterproof strip 8 with a structure imitating a hat brim and a de-icing coating stripe 9. The waterproof strip 8 with a structure imitating a hat brim is used to prevent external water from quickly wetting the lower hem of the coat 1 and to prevent external water from entering the fire-fighting boots. The de-icing coating stripe 9 is used to delay the icing time on the surface of the fire-fighting suit and to improve the efficiency of removing the ice covering on the surface of the fire-fighting suit.

[0027] For example, by providing a de-icing material coating on the side of the de-icing and flame-retardant layer 3 away from the human body surface, the water that is about to come into contact with the de-icing fire-fighting suit is not easily adhered to the surface of the fire-fighting suit, and the ice covering that has already formed on the surface of the de-icing fire-fighting suit is easily removed. The heat-insulating aramid felt 6 in the waterproof, moisture-permeable and heat-insulating layer 4 is coated with two layers of waterproof and moisture-permeable membranes 7 to form a composite structure, which can prevent the heat-insulating aramid felt 6 from absorbing water, because the barrier of the waterproof and moisture-permeable membranes 7 prevents water from being absorbed by the heat-insulating aramid felt 6. After the moisture condenses into water droplets, due to the action of gravity, the water droplets quickly slide down on the waterproof and moisture-permeable membranes 7 or are absorbed by the comfort layer 5. The de-icing coating stripe 9 has characteristics such as low surface energy, high polarity, and smoothness, which can delay the icing time on the surface of the fire-fighting suit fabric and improve the efficiency of removing the ice covering on the surface of the fire-fighting suit. The waterproof strip 8 with a structure imitating a hat brim can guide the external water flow, prevent the water on the coat 1 from quickly wetting the lower hem, and prevent the water on the trousers 2 from pouring into the fire-fighting boots. Through the synergistic effect of the above functions, the de-icing fire-fighting suit can effectively delay the icing time on the surface of the fire-fighting suit, improve the efficiency of removing the ice covering on the surface of the fire-fighting suit, reduce the wet and cold degree of the fire-fighting suit, and at the same time prevent water from quickly wetting the lower hem of the coat 1 and entering the fire-fighting boots, enabling firefighters to perform tasks in a cold and water-rich environment for a long time without being troubled by the icing of the protective clothing.

[0028] As an optional embodiment, the comfort layer 5 is made of a pure cotton fabric 10 and a sweat storage functional material 11. The comfort layer 5 includes an outer side in contact with the body and an inner side in contact with the waterproof, moisture-permeable and heat-insulating layer 4, and human sweat is conducted from the outer side to the inner side.

[0029] As an optional embodiment, the sweat storage functional material 11 is made of a superabsorbent resin.

[0030] For example, the comfort layer 5 is made of pure cotton fabric 10 and sweat storage functional material 11. The sweat storage functional material 11 has extremely strong moisture absorption and water retention functions, can quickly absorb and store the sweat discharged by the human body, and prevent the sweat from quickly putting the comfort layer 5 into a wet and cold state. After the sweat of the human body is absorbed by the pure cotton fabric 10 of the comfort layer 5 and conducted to the sweat storage material, the superabsorbent resin has strong water absorption and can quickly absorb the sweat. The sweat storage material after absorbing water will expand to a certain extent, and its expansion range is between 1 - 1.5 mm, which basically does not affect the softness of the overall fabric. Its good water retention can ensure that the water absorbed by the sweat storage material will not return to the comfort layer 5 due to fabric extrusion during the operation of the firefighter, so as to achieve the effect of reducing the wet and cold state inside the fire suit.

[0031] As an alternative embodiment, the waterproof and moisture-permeable membrane 7 is made of polytetrafluoroethylene.

[0032] As an alternative embodiment, the brim-like waterproof strip 8 of the upper garment 1 is arranged at the waist, and the brim-like waterproof strip 8 of the trousers 2 is arranged at the cuffs.

[0033] For example, the brim-like waterproof strip 8 can guide the external water flow, prevent the water on the upper garment 1 from quickly wetting the lower hem, and prevent the water on the trousers 2 from pouring into the fire boots.

[0034] As an alternative embodiment, the ice-repellent coating stripes 9 of the upper garment 1 are arranged on the front piece, back piece and cuffs, and the ice-repellent coating stripes 9 of the trousers 2 are arranged on the buttocks, waist and cuffs.

[0035] For example, the ice-repellent coating stripes 9 have characteristics such as low surface energy, high polarity and smoothness, can delay the icing time on the surface of the fire suit fabric, and improve the ice removal efficiency on the surface of the fire suit.

[0036] As an alternative embodiment, both the ice-repellent coating stripes 9 and the brim-like waterproof strip 8 are made of a composite of materials such as tungsten, graphite, polytetrafluoroethylene, water-repellent finishing agent, and waterborne polyurethane.

[0037] As an alternative embodiment, the ice-repellent coating stripes 9 are composed of a combination of diagonal stripes and horizontal stripes.
