The preparation method comprises the following steps: 1, adding zirconium carbide into a polymer solution, uniformly stirring, and then carrying out ultrasonic oscillation to prepare a polymer-ZrC suspension; 2, the yarn sequentially passes through a polymer-ZrC turbid liquid stock tank and a drying cylinder of a sizing machine, and preparing yarn / polymer / ZrC composite yarn; and 3, weaving the yarn / polymer / ZrC composite yarn to obtain the multifunctional fabric with the photothermal conversion function. The fabric has the following advantages: the fabric has excellent photothermal conversion function and anti-ultraviolet function, strong light absorption capability and high and adjustable photothermal conversion efficiency; the preparation process is simple, and the yarns are prepared by a traditional sizing process; the yarns are not damaged in the processing process, and the physical and chemical properties of the yarns are enhanced; and the fabric can be recycled for multiple times and is washable and good in cycling stability.

Description

technical field [0001] The invention relates to a preparation method of a light-to-heat conversion fabric, more specifically, the invention relates to a light-to-heat conversion multifunctional fabric and a preparation method thereof. Background technique [0002] As a new type of high-performance textile, photothermal conversion functional textiles are widely used in temperature control and energy saving, heat preservation and dehumidification, solar steam devices, seawater desalination, wastewater treatment and other fields. It has broad market prospects and can be used as another development path for traditional textiles. [0003] At present, the production of light-to-heat conversion functional textiles is mostly by microcapsule method and coating method. For example, Li Changlei of Tianjin University of Technology patented a light-to-heat conversion, heat storage and temperature-adjusting cellulose fiber and its preparation method (application number: CN201910700950.8)....
