Henan Fengjin Clothing Co., Ltd. has a keen insight into the pain points of the industry. Relying on its strong scientific research strength and innovative spirit, it has deeply cultivated the field of acid and alkali resistant protective equipment, reshaped industry standards with breakthrough technologies, and built a solid and reliable safety line for high-risk workers.
The company’s R&D team has successfully developed a new generation of nano-composite protective fabrics after three years of technical research to address the common disadvantages of traditional acid and alkali resistant work clothes, such as thickness, stuffiness, poor breathability, and limited activities. The fabric adopts a multi-layer structure design: the surface layer is a dense nano-coating, which uses molecular-level cross-linking technology to form a highly hydrophobic and acid-repellent protective film that can instantly block the penetration of strong acids and alkalis; the middle layer is a high-performance fiber reinforcement layer, which uses a special weaving process to increase the tear strength of the fabric by 3 times, effectively resisting the scratches of sharp chemical containers; the inner layer uses a bionic breathable membrane to simulate the breathing principle of human skin, with millions of micropores per square centimeter to ensure rapid discharge of sweat, and the body temperature is more than 5°C lower than that of traditional fabrics. According to the test of a third-party authoritative organization, the fabric can protect against 98% concentrated sulfuric acid and 30% sodium hydroxide solution for more than 8 hours, far exceeding the national standard, and the weight is reduced by 40%, which greatly improves the flexibility of operation.
In terms of process innovation, Fengjin Clothing breaks through the limitations of traditional garment production and introduces 3D stereoscopic cutting and seamless hot pressing technology. According to the characteristics of the physical activities of chemical and laboratory workers, a three-dimensional splicing design is adopted in key parts such as shoulders and elbows, so that the wearer can raise his hands, bend over, and other movements without restraint; and the seams abandon the traditional needle and thread stitching, and use high-frequency hot pressing technology instead, to eliminate the hidden dangers of pinhole water seepage and achieve all-round protection without dead angles. In addition, the work clothes are also equipped with humanized functional design: hidden acid and alkali concentration detection strips, which can monitor the degree of fabric erosion in real time; built-in breathable and moisture-conducting lining to avoid the discomfort caused by long-term wear; reflective warning strips and luminous signs to ensure the safety of night operations.
With outstanding technological innovation, Fengjin acid and alkali proof work clothes have been successfully used in more than 200 chemical companies such as PetroChina and Sinopec, as well as laboratories of scientific research institutions such as the Chinese Academy of Sciences and Tsinghua University. A large chemical group reported that since changing to new acid and alkali proof work clothes, the rate of heat stroke caused by stuffiness among employees has dropped by 75%, the work efficiency has increased by 20%, and no safety accidents caused by acid and alkali penetration have occurred in three years. This innovative achievement not only fills the technical gap of domestic high-end acid and alkali protection equipment, but also promotes the transformation and upgrading of the industry from “passive protection” to “comfortable and safe integration”.
In the future, Henan Fengjin Clothing will continue to increase R&D investment and explore the application of intelligent protection technology in the field of acid and alkali protection, such as developing intelligent work clothes that can monitor environmental data in real time, further improving the safety level of operations in highly corrosive environments, and escorting the safe production of high-risk industries such as chemical industry and scientific research, helping enterprises to achieve a dual improvement in safety and efficiency.
