Core Viewpoint - The rising temperatures have led to an increased popularity of "cooling fabric technology" in the apparel and home textile markets, with various brands launching products that claim to provide an instant cooling sensation upon contact [1][4]. Group 1: Product Offerings - Numerous brands, including Muji, Uniqlo, and IKEA, have introduced cooling fabric collections this summer, featuring items like pillowcases, bed sheets, and clothing with labels indicating their cooling properties [4][2]. - A specific product, the "cooling pillowcase," is made of 60% nylon and 40% lyocell, designed to provide an instant cooling sensation and a soft, smooth touch [2][4]. Group 2: Technology Behind Cooling Fabrics - Cooling fabrics achieve their effects primarily through modifications in fiber structure, molecular arrangement, and moisture evaporation [6]. - The cooling sensation is created when the fabric absorbs body heat, leading to a rapid temperature drop upon contact with the skin [4][7]. Group 3: Standards and Evaluation - There are national and industry standards for assessing cooling fabrics, with a Qmax value greater than 0.15 indicating a product can be classified as cooling [7]. - The GB/T35263-2017 standard outlines testing methods for the cooling performance of textiles, applicable to various fabrics and products [7]. Group 4: Longevity of Cooling Effect - The cooling effect is temporary and diminishes as the fabric temperature approaches that of the body, with repeated use and washing further reducing its effectiveness [8][10]. - Brands like Tennie Wennie explicitly state that the cooling effect will weaken over time with usage [8]. Group 5: Consumer Guidance - Consumers are advised to look for products that meet national cooling standards rather than solely focusing on high Qmax values, as comfort also depends on the fabric's thermal conductivity and moisture absorption [9][10]. - The term "ice silk" is often used for marketing purposes and lacks a clear definition in national standards, with many products containing synthetic fibers that may not provide the expected comfort [9].
