Problems solved by technology

Among the existing preparation methods, most of them focus on the unilateral research of porous matrix composite phase change heat storage materials and photothermal conversion materials, while the research on photothermal conversion synergistic phase change temperature regulation function is still relatively small.
At the same time, most of the research is aimed at the surface of fibers or fabrics, and there are relatively few functional studies using yarn as a carrier, and there are problems such as complex processes, cumbersome processes, and low production efficiency.

Abstract

The invention relates to sized and coated photo-thermal phase change composite yarn and a preparation method thereof. The method comprises the following steps of 1, preparing a polyvinyl butyral / zirconium carbide / aluminum oxide suspension and a polyvinyl butyral solution; 2, preparing a molten paraffin material; and 3, by taking a polyvinyl butyral / zirconium carbide / aluminum oxide coating as a surface layer, paraffin as a middle layer and terylene / polyvinyl butyral / zirconium carbide / aluminum oxide composite yarn or pure terylene yarn as core yarn, preparing terylene / polyvinyl butyral / zirconium carbide / aluminum oxide / paraffin composite yarn through a coating method. The method has the advantages that 1, the photo-thermal conversion function is achieved, and the photo-thermal conversion efficiency is relatively high; 2, the phase change function is achieved, and the heat storage and temperature adjustment can be achieved; 3, the preparation method is simple, economic and rapid; and 4, the service life is long, and the shape stability is better.

Description

technical field [0001] The invention relates to a preparation method of a photothermal phase change composite yarn, more specifically, the invention relates to a sizing-coated photothermal phase change composite yarn and a preparation method thereof. Background technique [0002] The development of functional textile materials is a trend in the textile industry at present. With the development of economy and society, textile materials should have many functional features in addition to conventional warmth and covering, such as phase change temperature regulation, light-to-heat conversion, Conductive etc. [0003] Li et al. used zirconium carbide as the photothermal conversion material to prepare viscose composite fibers with photothermal effect by wet spinning method. The near-infrared light absorption rate of the composite fiber can reach 90%, and when irradiated with infrared light for 60s, its temperature can be increased by 39.4 °C compared with the original viscose fib...
