Description

Technical Field

[0001] This utility model relates to a firefighter protective suit that combines impermeability and warning functions, belonging to the field of firefighter protection. Background Technology

[0002] Personal protective equipment (PPE) for firefighters is crucial for their safety. Taking firefighting protective clothing as an example, this equipment is specialized clothing worn by firefighters during firefighting and rescue operations to protect their torso, head, neck, arms, and legs. From the outside in, this clothing mainly consists of an outer layer, a waterproof and breathable layer, a thermal insulation layer, and a comfort layer. Key performance characteristics include flame retardancy, thermal stability, shrinkage rate, surface moisture resistance, tensile strength, tear strength, and impermeability. The waterproof and breathable layer, in addition to thermal stability requirements, also requires impermeability, specifically hydrostatic pressure resistance. The waterproof and breathable fabric itself and its seams must withstand a hydrostatic pressure of no less than 50 kPa after 25 washes. Currently, the outer layer of existing firefighting protective clothing is primarily made of woven fabric. Therefore, water can seep through the outer woven fabric and remain between the outer layer and the waterproof and breathable layer. This water accumulation increases the firefighter's load and poses a risk of burns from high-temperature vaporization. Meanwhile, there is also a technical need for reflective warning in the dense smoke environment of a fire scene. Currently, the existing reflective strips for firefighters are not very reasonable. For example, the reflective strips designed on the front and back of the uniform are usually horizontal structures, which do not fully take into account the essential equipment that firefighters need to carry on the front and back of the uniform at the fire scene, such as walkie-talkies and breathing apparatus. Carrying essential equipment often obscures part of the reflective strips on the front and back of the uniform, affecting the reflective warning effect of the reflective strips. Summary of the Invention

[0003] In view of the existing problems of water seepage in the outer layer and partial obstruction of reflective strips in firefighter protective clothing, this utility model designs a firefighter protective clothing that combines anti-seepage and warning functions. An adhesive strip is fixed to the seam of the composite outer layer inside the jacket, pants and protective hat to meet the anti-seepage requirements of the firefighter protective clothing. The structural design of the reflective strips of the firefighter protective clothing has both a warning function and adapts to the needs of front-line combat.

[0004] The technical solution adopted by this utility model is: a firefighter protective suit with both anti-seepage and warning functions, including a protective hat, a jacket and trousers that are integrated into one piece, as well as adhesive strips and reflective strips. The outer layer of the protective hat, jacket and trousers is a composite outer layer, and the suit also includes a backpack, which is located on the back of the jacket.

[0005] A strip of adhesive is fixed to the seam of the inner surface of the composite outer layer of the top, pants and protective hat. A reflective strip is fixed to the composite outer surface of the two sleeves of the protective hat, the placket of the top, the two sides of the backpack and the two legs of the pants.

[0006] The technical effects of this utility model are: 1. By fixing a strip of adhesive to the seam of the composite outer layer inside the firefighter's protective clothing top, pants and protective hat, the firefighter's protective clothing can achieve the anti-seepage function, thereby avoiding the problem of water seeping into the inner side of the outer layer and remaining between the outer layer and the waterproof and breathable layer, which would cause weight increase and the danger of water vaporization at high temperature burning the firefighter.

[0007] 2. The reflective strips on the surface of firefighters' protective clothing are designed to provide both reflective warning and prevent the necessary equipment carried from obstructing the view of the reflective strips.

[0008] 3. The backpack's structural design can effectively protect the air cylinders of the breathing apparatus carried by firefighters from external smoke and water contamination. Attached Figure Description

Detailed Implementation

[0016] like Figures 1 to 6 As shown, a firefighter protective suit with both impermeability and warning functions includes an integrated protective hat, jacket and pants, as well as adhesive strips 2, reflective strips 3 and backpack 4. The outer layer of the protective hat, jacket and pants is a composite outer layer 1.

[0017] The composite outer layer 1 is composed of polyurethane adhesive 1-1, polytetrafluoroethylene direct-permeable membrane 1-2 and outer woven fabric 1-3. The outer woven fabric 1-3 and polytetrafluoroethylene direct-permeable membrane 1-2 are bonded together by multiple polyurethane adhesive 1-1.

[0018] A backpack 4 is sewn onto the back of the jacket. A strip of adhesive 2 is attached to the seam of the composite outer layer 1 inside the jacket, pants and protective hat, respectively, to achieve the anti-seepage function at the seam, that is, the hydrostatic pressure resistance reaches 60kPa and the micron-level particle filtration efficiency reaches 99%, thereby resisting the intrusion of water spray and dust from the outside of the fabric.

[0019] A reflective strip 3 is sewn or attached to the surface of the composite outer layer 1 of the protective hat, the two sleeves of the jacket, the placket, the two sides of the backpack 4, and the two legs of the pants.

[0020] Among them, the reflective strip 3 on the protective hat is set vertically, with one end set at the brim of the protective hat and the other end set at the seam between the protective hat and the back of the jacket.

[0021] The reflective strip 3 on the placket is set vertically and is a reflective strip sewn or attached along the length of the placket;

[0022] The reflective strips 3 on both sides of the backpack 4 are set vertically. One end of the two reflective strips 3 is set on the shoulders of the protective suit, and the other end of the two reflective strips 3 is set on the waist of the protective suit.

[0023] The reflective strips 3 on the two sleeves and two trouser legs are all circular structures sewn or attached.

[0024] The distance between the reflective strips 3 on both sides of the backpack 4 and the backpack 4 is 197-203mm respectively;

[0025] The distance between the two reflective strips 3 on the sleeves and the cuffs is 114-226mm;

[0026] The distance between the reflective strip 3 on both pant legs and the pant leg opening is 248-252mm;

[0027] The reflective strip's 3-structure design, in addition to its conventional reflective function, boasts a retroreflective coefficient exceeding 300 cd / lx•m at 5 degrees and 12 minutes. 2 Other angles also meet the requirements of XF10-2014 "Firefighters Extinguishing Fires" for "Reflective Markings".

[0028] The reflective strip 3 includes a polyimide woven fabric 3-1, reflective glass microbeads 3-2, and a polyurethane hot melt adhesive layer II 3-3. A layer of polyurethane hot melt adhesive layer II 3-3 is coated on one side of the polyimide woven fabric 3-1, and multiple reflective glass microbeads 3-2 are pasted on the other side of the polyimide woven fabric 3-1. The width of the reflective strip 3 is 57-63mm.

[0029] The adhesive strip 2 is composed of a polytetrafluoroethylene barrier layer 2-1 coated with a polyurethane hot melt adhesive layer Ⅰ2-2, and the width of the adhesive strip 2 is 19-21mm.

[0030] Example 1: At the seam of the inner surface of the composite outer layer 1 of the shirt, pants and protective hat, adhesive strips 2 with a width of 19mm are respectively attached;

[0031] Reflective strips 3, each 60mm wide, are sewn or attached to the surface of the composite outer layer 1 of the protective hat, the two sleeves of the jacket, the placket, the two sides of the backpack 4, and the two legs of the pants.

[0032] The distance between the reflective strip 3 on both sleeves and the cuff is 160mm;

[0033] The distance between the reflective strip 3 on both pant legs and the pant leg opening is 250mm;

[0034] The distance between the reflective strips 3 on both sides of the backpack 4 and the backpack 4 is 200mm.

[0035] After attaching an adhesive strip 2 to each of the seams on the inner surface of the composite outer layer, it is then sewn together with the edges of layers such as the insulation layer and the comfort layer to finally form the firefighter protective suit.

[0036] When firefighters are engaged in firefighting and rescue operations, they wear protective suits and carry essential equipment such as walkie-talkies, which can be attached to the front of the suit. The backpack (4) can hold essential equipment such as empty exhalation cylinders. At the fire scene, regardless of rain or high-pressure water jets, rainwater or extinguishing water sprays onto the firefighters. Thanks to the adhesive strips (2) secured to the seams of the inner surface of the outer composite layer (1) of the protective suit, rainwater or extinguishing water cannot enter the suit. This overcomes the problem of increased weight and the risk of burns from high-temperature vaporization caused by water ingress in existing protective suits. Especially at night or in dense smoke conditions at a fire scene, the reflective strips (3) on the protective suit are structurally designed to prevent obstruction of reflective strips by essential equipment, ensuring a clear view of the firefighter's movement and facilitating command and dispatch.
