Problems solved by technology

[0013] In the present invention, the phase change microcapsules are uniformly dispersed in the aqueous solution of nitrogen methylmorpholine nitrogen oxide with a concentration of 50 wt%, and then the method of low vacuum dehydration is adopted, which overcomes the problem of directly dissolving the phase change microcapsules in a high vacuum state in the traditional preparation method. The microcapsules are directly placed in the high-viscosity spinning solution, resulting in poor dispersibility and easy breakage. A polymer / phase change microcapsule composite fiber with good dispersibility and less prone to breakage and loss and its preparation method are provided. Thereby improving the addition efficiency of phase change microcapsules and the mechanical properties of the final composite fiber

Abstract

The invention relates to a polymer / phase-change microcapsule composite fiber and a preparation method thereof. The preparation method comprises the following steps: dispersing phase-change microcapsules in an aqueous N-methyl morpholine oxynitride solution with a concentration of 50 wt% so as to obtain dispersion liquid; adding a polymer into the dispersion liquid, carrying out mixing under stirring in a low vacuum state and then carrying out dehydration so as to obtain mixed dispersion liquid; then carrying out stirring and dehydration in a high vacuum state so as to prepare a functional spinning solution; and finally, carrying out spinning so as to prepare the polymer / phase-change microcapsule composite fiber. The preparation method provided by the invention is simple, flexible and low in cost and overcomes the disadvantages of poor dispersibility and proneness to damage caused by direct addition of phase-change microcapsules into a high-viscosity spinning solution in a high-vacuum state in the prior art; and in the eventually prepared composite fiber, the phase-change microcapsules are good in dispersibility and not prone to damage, so the eventually prepared composite fiber is high in the addition efficiency of the phase-change microcapsules and has excellent mechanical properties and good economic value and promotion value.

technical field [0001] The invention belongs to the field of composite fibers and relates to a polymer / phase change microcapsule composite fiber and a preparation method thereof. Background technique [0002] Phase-change microcapsules are phase-change composite materials made of phase-change materials, such as paraffin, wrapped in microcapsule wall materials, such as polymethacrylic acid, by using capsule technology. The diameter of phase-change microcapsules is generally at the micron level. It can be added into the base material as an additive to make a phase-change functional composite material, and the phase-change functional composite material is widely used in the fields of clothing and medical supplies. [0003] The phase change fiber is prepared by using the phase change microcapsule. The phase change fiber has the phenomenon of heat absorption at high temperature and heat release at low temperature at about 30°C, and it has the function of real-time temperature adj...
