Business News, November 5th: With differentiation, functionality and high functionality, and the upgrading of functional fiber materials, the protective capabilities of occupational protective clothing have significantly improved. Professional attire, which is “escorted” by high-tech materials and incorporates traditional technological elements, will become a potential profit point in the clothing segment market in the future. At the second China Special Fabrics Summit Forum held last week, the participants reached a consensus. Increasing the development of high-performance, functional and differentiated fibers, expanding their application in key areas such as functional textiles, green and environmentally friendly ecological textiles, and industrial textiles, and relying on technological contribution to increase the added value of products will become the future chemical fiber industry and the purpose of separate diligence in the textile industry.
New materials integrate clothing uniqueness
According to Wang Yaomin, secretary-general of the China Professional Clothing Industry Association, at the just-concluded 2010 World Expo, high-tech professional attire emerged, showing the high-tech and The infinite fascination of new material. For example, clothing made of Flycool cooling fabrics can produce a momentary cold sensation that increases the temperature by 1°C to 2°C when in contact with the skin. Long-term sunlight exposure can produce a cooling temperature difference that increases the temperature by 3°C to 5°C. It also has moisture absorption and wicking properties. Sweat and anti-ultraviolet effects. This kind of cool fiber “cold fabric” has higher moisture regain and fiber heat dissipation rate than ordinary fibers. When wearing this series of clothing, you can increase the air conditioner by 1°C, saving 5% to 6% of electricity bills and reducing emissions by about 0.62kg. Carbon content. A company in Taiwan has developed “thermal fabric” clothing that generates heat naturally. The surface temperature before wearing is 27.4°C and can rise to 30.2°C after 15 minutes. It is called thermal clothing that does not use electricity.
During the World Expo, the kimono worn by the Japan Pavilion service staff was made of heat-resistant bioplastic fiber and Kyoto’s traditional silk fabric-Tango crepe. After the Expo, these uniforms will be transported back to Japan along with other equipment of the Japan Industrial Pavilion, and will be recycled and reused for processing and production. In addition, a variety of new functional fabrics such as anti-static, anti-oil stain, high temperature resistance, anti-flame retardant, etc., as well as professional attire made from these fabrics are dazzling.
Workwear calls for the “three modernizations” of fiber
Yang Wenfen, director of the National Labor Protection Products Quality Supervision and Inspection Center, said that hollow fiber, Kermel (aromatic polyamide argon amine) fiber, PBI The upgrading of materials such as (polybenzimidazole) fiber, microfiber, shape memory material, far-infrared ceramic fiber and high-strength fiber has significantly improved the protective capabilities of protective clothing. Nowadays, protective clothing is developing in the direction of multi-functional, composite and systematic, such as flame retardant and anti-static compatibility, chemical protection and moisture permeability, etc. In addition to meeting the protective measures, in the future protective clothing will also consider more comfort functions such as reducing the load on the clothing, adjusting the microclimate inside the clothing, and performing antibacterial processing. In addition to the traditional flame retardant and antistatic fields, the continuous emergence of new materials and processing techniques such as antibacterial and deodorant materials and retroreflective marking materials are also constantly expanding the application scope of protective clothing. At the same time, fiber raw materials are required to be differentiated, functional and high-end. Functional development.
According to Cheng Longdi, director of the Ministry of Education’s Key Laboratory of Textile and Fabric Technology at Donghua University and the National Fabric R&D Center, the reason why protective clothing has various protective functions is mainly due to the use of various functional fabrics. He said that functional materials have excellent electrical, magnetic, optical, thermal, acoustic, mechanical, chemical, and biomedical functions, or have special physical, chemical, and biological effects, and can realize mutual conversion of functions. They are mainly used for High-tech materials that are widely used in various fabrics for the manufacture of various fiber materials or finishing materials. Functional fabrics are textile fabrics that use functional fiber materials or undergo special textile dyeing and finishing processes to have special functions. Functional materials mainly include superconducting fiber materials, biomedical materials, solar cell materials, ecological environment materials, smart materials, etc. At present, research on traditional textile functional fiber materials mainly focuses on carbon fiber, aramid 1414, ultra-high molecular weight polyethylene (UHMWPE), polyimide, polyphenylene sulfide (PPS), PBO (polyphenylene benzoyl sulfide) bisoxazole), M5 fiber (liquid crystal aromatic heterocyclic polymer poly-2,5-dihydroxy-1,4-phenylenepyridodiimidazole), SiBNC ceramics and other fiber materials.
Characteristics.
Introduce high-tech materials such as functional fibers into the field of professional clothing protection, transform cutting-edge technologies into application technologies, and focus on the research and development of professional clothing in special fields such as aviation, navigation, metallurgy, electric power, and petrochemicals to meet high temperature resistance , acid and alkali resistance, fire protection, radiation protection, anti-static and other special protection requirements will be a key for the professional clothing industry to move from “food and clothing” to “well-off”.
