Quanzhou garment industry developed PM2.5 protective clothing

In response to increasing hazy weather and the growing public demand for better health protection, Quanzhou Textile and Apparel Industry Co., Ltd. has launched an initiative to develop "PM2.5 protective clothing." The goal is to create garments that can effectively block harmful particles found in smog, offering a practical solution to protect people from environmental pollutants. Renewable and biodegradable fabrics, alongside PM2.5 protective clothing, have become key focuses of R&D projects at Fujian Longfeng Textile Technology Industrial Co., Ltd. According to Wei Hao, deputy director of the R&D department, developing such products is a challenging task with no clear blueprint to follow. “We are venturing into uncharted territory,” he said, emphasizing the need for innovation and continuous experimentation. Inspired by research showing higher rates of dermatological issues in the Jing-Jin-Ji region—possibly linked to environmental factors—Wei Wei noted that Japan has developed clothing that reduces skin disease incidence through experimental findings. This inspired the team to explore how clothing could serve as a barrier against environmental harm. “The issue of smog today is primarily about excessive harmful particles in the air,” Wei explained. “We aim to make a breakthrough in this area.” Over the years, Quanzhou’s textile industry has focused on functional fabrics, particularly those with antibacterial properties. Fengzhu Textile recently introduced a new fabric called “Long-lasting antimicrobial silver ion fabric,” which has gained significant market interest. According to the company’s product development manager, their expertise lies in cotton textiles, and they continuously seek to enhance their offerings by blending other materials with cotton. “By incorporating silver nanomaterials during the spinning process, our fabric maintains long-term antibacterial effectiveness,” the manager explained. Unlike traditional methods that rely on additives, which lose potency after multiple washes, the silver ion-based technology offers a more durable and effective solution. This advancement has positioned Fengzhu Textile as a leader in innovative textile solutions.

Regulating Valve

Regulating valve is a fluid control device, it can control fluid flow, pressure, temperature and other parameters, in order to achieve the purpose of regulating fluid flow characteristics. It is composed of a piston or ball spool, in which there is a manual or electric mechanism with adjustment function, it can control the position of the piston or ball spool, so as to change the pressure and flow rate in the valve, so as to adjust the flow characteristics of the fluid.

The main function of the regulating valve is to adjust the flow rate, pressure and temperature, so that the fluid flow characteristics are more stable, so as to improve the efficiency of the fluid. It can regulate the flow of fluid to keep it at a low level, thus saving energy; The pressure of the fluid can also be adjusted to keep it at a low level, thus reducing noise in the piping system; The temperature of the fluid can also be adjusted to keep it at a low level, thus preventing condensation in the piping system, etc.
