Description

Technical Field

[0001] This invention application relates to a firefighter protective suit that combines anti-icing and warmth retention properties. Through the coordinated design of materials and structure, the anti-icing and warmth retention properties of the equipment are achieved, which can meet the warmth needs of firefighters in northern regions when operating in low temperatures. At the same time, it can also effectively remove ice from the protective suit after it comes into contact with water, thereby improving the efficiency of personnel in low-temperature environments. Background Technology

[0002] Temperature differences between northern and southern my country are significant. In Hainan in the south, winter temperatures can reach as low as 15°C, while in Heilongjiang in the north, winter temperatures can plummet to -30°C, with Mohe even recording a low of -52.3°C. Currently, the GA10-2014 standard for firefighter protective clothing covers the entire country and does not differentiate between regions based on temperature variations. Generally, firefighters in the south wear three layers of protective clothing to improve breathability, while firefighters in the north wear a thicker four-layer suit to enhance warmth. A three-layer suit typically consists of an outer layer, a waterproof and breathable layer, and either a thermal insulation layer or a comfort layer. A four-layer suit typically consists of an outer layer, a waterproof and breathable layer, a thermal insulation layer, and a comfort layer. While the thermal insulation and waterproof and breathable layers can be thickened to improve warmth, the overall equipment has a 3.5kg weight limit, limiting the extent to which the fabric thickness can be increased.

[0003] In the north, firefighters typically wear underwear, sweaters or fleece jackets, and training uniforms during daytime training. Upon receiving an alarm, they immediately put on their firefighter protective suits and respond to the call.

[0004] In northern regions, firefighters typically rest in thermal underwear at night. Upon receiving an alarm, they might wear a sweater or fleece, then don their firefighting protective suit before responding. Even with these layers of underwear, sweaters or fleece, and four layers of firefighting protective suit, firefighters still feel cold in cold regions like Harbin. Therefore, it is necessary to develop a firefighting protective suit with excellent thermal insulation properties, while also addressing the issues of keeping the collar, wrists, cuffs, and hem of the suit warm.

[0005] Currently, firefighters' protective clothing consists of a collar made of woven fabric, a waterproof and breathable membrane composite nonwoven fabric layer, a nonwoven insulation layer, and another woven fabric. The neck area, where the collar connects the head and torso, is prone to drafts and requires insulation. The cuffs are typically made of ribbed fabric from meta-aramid fibers, whose insulation and cut resistance need improvement. The hem is usually composed of a woven fabric outer layer, a waterproof and breathable membrane composite nonwoven fabric layer, a nonwoven insulation layer, and a woven comfort layer. Located about 5cm above the bottom of the jacket, below the waist belt, this area is prone to drafts and requires insulation. Other parts of the jacket and trousers are typically composed of a woven fabric outer layer, a waterproof and breathable membrane composite nonwoven fabric layer, a nonwoven insulation layer, and a woven comfort layer. Current equipment primarily focuses on safety and lacks design considerations for warmth.

[0006] Meanwhile, water is the most commonly used extinguishing agent for firefighters. When using water to extinguish fires in low-temperature environments, water often freezes on the outer layer of their clothing. This restricts joint movement and increases the weight burden on firefighters, thus affecting their operational efficiency. Current firefighter protective clothing consists of woven fabric for the outer layers of the upper and lower garments. The surface of this fabric has many short fibers that easily freeze when wet. Water can also penetrate the outer woven fabric and freeze on the inner side. Therefore, designs with enhanced anti-icing properties are needed. Summary of the Invention

[0007] To address the problem that existing firefighter protective suits cannot meet the requirements of firefighters in northern regions for both warmth and anti-icing performance, this invention provides a firefighter protective suit that combines both anti-icing and warmth properties.

[0008] The design incorporates materials and structure to create firefighter protective suits that combine anti-icing and warmth retention. This includes applying a hydrophobic polymer coating to the traditional outer layer to enhance its anti-icing properties; introducing lower thermal conductivity fibers such as polyimide or aramid fiber to the traditional meta-aramid and para-aramid fibers; performing three-dimensional finishing or adhesive finishing on the traditional membrane composite structure; incorporating air gaps into the traditional four-layer fabric design; adding brushed knit fabric to the traditional collar area to improve warmth; thickening the traditional ribbed cuffs to enhance warmth; and adding para-aramid fibers to the traditional meta-aramid ribbed cuffs to improve cut resistance, thereby reducing cut injuries caused by frostbite and reduced dexterity of firefighters' hands in winter.
