Problems solved by technology

The elastic energy storage temperature-regulating fiber has the advantages of low cost, low pollution, high enthalpy, and strong energy storage and temperature-regulating ability, but the phase change medium in this patent will flow around during the phase change process, resulting in the The uneven distribution in the phase change fiber affects the temperature adjustment effect of the phase change fiber. Moreover, in the process of preparing the elastic energy storage phase change fiber, it is often difficult for the phase change medium to be evenly distributed in the second part

Abstract

The invention discloses a phase-change energy-storing fiber. The phase-change energy-storing fiber is of a skin-core structure which comprises a skin layer and a core layer, wherein a skin layer raw material is a thermoplastic polymer; and a core layer raw material is a mixture of the thermoplastic polymer, clay mineral powder and a phase-change material. A preparation method of the phase-change energy-storing fiber comprises the following steps: (1) weighing 2-20 parts of the phase-change material and 5-20 parts of the clay mineral powder in parts by weight, uniformly mixing the weighed phase-change material and clay mineral powder by virtue of ultrasonic oscillation under a vacuum condition, putting the mixture into a vacuum oven so as to obtain a composite phase-change material, and uniformly mixing 60-90 parts of thermoplastic polymer with the prepared composite phase-change material, so as to obtain the core layer raw material; and (2) carrying out melt spinning on the thermoplastic polymer, as skin layer raw material, and the core layer raw material by virtue of a compound spinning machine, so as to obtain the phase-change energy-storing fiber being of the skin-core structure. The preparation method is simple and low in cost, and the prepared phase-change energy-storing fiber has large phase-change enthalpy and a uniform temperature regulation effect.

Description

technical field [0001] The invention relates to the field of functional fibers, in particular to a phase change energy storage fiber and a preparation method thereof. Background technique [0002] With the development of the global economy and the improvement of people's living standards, the requirements for clothing and household textiles are increasing day by day. In terms of comfort in contact with human skin, people are pursuing a fiber that can freely adjust the internal temperature of textiles according to changes in external temperature. The human body is in a comfortable state. Therefore, the research and development of phase change fibers with bidirectional temperature regulation function is increasingly important. [0003] The heat storage and temperature adjustment function of phase change fiber is mainly realized by the heat absorption and heat release of phase change material during the phase change process. Therefore, the selection of phase change materials ...
