Low-temperature cold weather industrial environments bring dual safety threats to workers: frostbite and low-temperature injury caused by long-term exposure to cold air, and flame, high-temperature splash, and combustion hazards inherent in industrial operations. Cold weather fire resistant protective clothing is specially developed for low-temperature hazardous working scenarios, perfectly combining excellent cold insulation performance and professional flame retardant protection, breaking the limitation that traditional fire-resistant clothing is thin and not suitable for winter use and ordinary cold-proof workwear lacks flame retardant functions. This protective clothing adopts a three-layer composite structure of outer flame retardant layer, middle warm insulation layer, and inner skin-friendly comfort layer, realizing the dual protection of cold resistance and fire resistance without sacrificing the flexibility and practicability of workwear.

The outer layer of the cold weather fire resistant protective clothing is made of high-performance permanent flame retardant aramid blended fabric, which has stable flame retardant and heat insulation properties. It can effectively resist open flame impact, high-temperature heat radiation, and molten metal splashes, and will not produce toxic and harmful gases when burned, ensuring the personal safety of workers in case of fire hazards. The middle warm layer uses high-density fluffy thermal insulation cotton with low thermal conductivity, which can lock body heat efficiently, resist low-temperature environments of minus 20 degrees Celsius and below, and effectively prevent body heat loss during long-term outdoor winter operations. The inner layer is made of soft and skin-friendly antibacterial fabric, which is breathable and sweat-absorbent, avoiding the cold and damp feeling caused by sweat accumulation during work, and greatly improving the wearing comfort in cold weather.

In terms of structural design, this cold-resistant fire protective clothing adopts an integrated tight-fitting design with reinforced windproof cuffs, elastic waistband, and windproof stand collar, which can effectively block cold wind infiltration and enhance the overall warm effect. All key stress parts such as elbows and knees are reinforced with thickened fabrics to improve wear resistance and extend service life. The overall version is ergonomically optimized, which can adapt to various working postures such as squatting, bending, and stretching, without affecting the flexibility of workers' operation. It is widely used in winter operation scenarios such as northern industrial production, outdoor electric power maintenance, petroleum and natural gas exploitation, metallurgical forging, and cold-region chemical operations, providing reliable dual safety protection against cold and fire for frontline industrial workers in low-temperature environments.
