　　 It is neither cold nor hot, which is the ideal demand of consumers for clothing or home textile bedding performance. Because there is no such material in nature, the concept of cool and warm clothing perception is derived from clothing or home textile bedding. In recent decades, the scientific research and development of such materials has also been deepening.

　　 In 2006, the scientific research team led by Miao Xiaoguang, a national model worker, a professor level senior engineer and a Beijing expert with outstanding contributions who enjoys special government transfer subsidies from the State Council of Beijing Xuelian Cashmere Co., Ltd., developed and industrialized the microencapsulated phase change energy storage casein modified acrylic fiber, Turn to the research and development of high energy storage solid solid phase transition energy storage materials with more high-tech content. The research team has developed the processing technology and master batch of elastic high solid solid phase enthalpy change energy storage textile materials with 800-2000 molecular weight polyethylene glycol as soft segment, isocyanate as hard segment and chain extender for 12 years. The master batch can be dissolved in sulfoxide solvent and melted at high temperature. According to the mold test, the master batch of the series absorbs heat by virtue of the inherent solid solid phase transition characteristics of the material itself between the external temperature of 20-42 ℃, and releases heat by virtue of the inherent solid solid phase transition characteristics of the material itself when the external temperature drops to - 18 to 15 ℃. During this process, the temperature of the fiber temperature layer is basically kept constant through frequent automatic conversion of heat absorption and desorption, and the phase transition enthalpy can reach 45 joules/g, When the melting temperature is above 105 ℃, the casting film has good elasticity and is resistant to boiling water and non stick.

　　 After the achievements came out, there were obstacles in the process of transforming into scientific and technological achievements. How to use these masterbatches to produce products with corresponding functions and meeting the market demand is the key to the next step. During the period from 2018 to 2014, the team led by Miao Xiaoguang, under the cooperation with the team led by Associate Professor Wang Ran of Beijing Institute of Fashion Technology, has successively made attempts in fiber spinning, fiber or fabric coating, melt blown non-woven fabrics, and melt blown flocs, and finally decided to settle down on melt blown non-woven fabrics as the first step. In June 2024, the scientific research team finally optimized the melt blown process, successfully developed melt blown non-woven fabrics with different weights, and then developed floc materials made of cashmere or yak hair or fluffy cotton.

　　 Recently, its cooperation team has been growing, and has successively developed flame-retardant and far-infrared series of melt blown non-woven fabrics and wadding sheet materials mixed with cashmere or yak hair or fluffy cotton by using these achievements, and combined with piezoelectric heating technology, developed the processing technology of piezoelectric heating solid solid phase to high heat storage intelligent temperature regulating insoles and intelligent temperature regulating shoes, And these flocs and non-woven fabrics with high solid solid enthalpy change have been used to develop high heat storage intelligent temperature regulating hats, jackets, ski shirts, quilts and other products, accelerating the industrialization of elastic high solid solid enthalpy change textile materials, and the products are expected to be applied in ice and snow sports projects.
