Bio-based or petroleum-based energy storage phase change materials are applied to melt spinning, and are developed, applied and mass-produced in different carriers, including long fibers, short fibers and spunbonded nonwovens, with enthalpy higher than 25J/G; That is, it responds to the promotion of national energy storage applications, and also aims to improve people's livelihood and improve the quality of life of modern people. It can also be used in special clothing, bedding and outdoor special environment, such as troops and fire fighting. As we all know, phase change materials for home textiles can't be produced normally in melt spinning at present because of their extremely low volatilization point. There are only surface treatments such as phase change coating, padding, printing, etc. In the market, which are easy to lose powder and not resistant to washing. Only wet-spun viscose and lyocell fibers are implanted with chemical fibers. Our company focuses on pre-dispersing and wrapping phase change materials in one or more characteristic materials to make high-temperature resistant microcapsules, and then grafting them on different carriers for melt spinning to produce staple fibers and spunbonded nonwovens used in different fields, which solves the application of phase change materials in melt spinning of different carriers; So as to improve the temperature resistance of the phase change material and reduce the volatilization of the phase change material at high temperature; The highest enthalpy can reach above 32 j/g. There are eight invention patents and six utility patents in application, and five utility patents have been issued. According to the situation that the country vigorously promotes energy storage, special polymer materials and chemical fiber, through in-depth understanding of customers, in the next five years, phase change fiber will be a functional material widely used in military, medical, civil and sanitary materials at home and abroad; Because of the particularity of its products, in the next five years, with the development and use of the market, the output value will reach several billion, with great potential. The company has been constantly improving, and the third generation of products will also be put on the market, with higher enthalpy and better effect.
