使体感温度直降5摄氏度 稀土面料织就“清凉铠甲”

Core Viewpoint - The article highlights the innovative breakthroughs in textile materials utilizing rare earth technology, specifically the development of a cooling fabric that integrates advanced thermal control mechanisms, which is set to benefit workers in high-temperature environments [1][2]. Group 1: Product Development - The Tianjin branch of the Baotou Rare Earth Research Institute is producing a new type of fabric with a "personal air conditioning" feature, designed to provide cooling for workers in high-temperature conditions [1]. - The fabric, made from "rare earth infrared reflective hollow heat-insulating polyamide fiber," employs a dual cooling mechanism that reflects over 90% of solar radiation heat while achieving a 93% infrared transmittance rate [1][2]. - The fabric can lower perceived temperature by 3-5 degrees Celsius and maintains performance stability even after 50 washes, outperforming national standards by two times [2]. Group 2: Technological Innovation - The research team spent two years overcoming key technological challenges, resulting in a hollow porous fiber structure that enhances breathability by 30% and sweat discharge efficiency by 40%, while also providing antibacterial and UV protection [2]. - The production line for this technology is under construction in the Baotou Rare Earth High-tech Zone, with plans to scale up production capabilities significantly by 2025 [2]. Group 3: Market Potential - The global temperature-regulating fiber market has surpassed 100 billion yuan, while the penetration rate of rare earth functional textiles in China is still below 1%, indicating substantial growth potential for this innovative combination of rare earth materials and textiles [2]. - Collaborative efforts are underway with Nankai University to develop adaptive temperature-regulating clothing, which could further expand the applications of rare earth materials in everyday textiles [3].
