Technical Field

The invention relates to a blanket with a photothermal response function and a preparation method thereof, belonging to the technical field of textile materials.

Background

The blanket as a household textile becomes a necessary article for home use, but with the improvement of living standard of people, the single heat-preservation function of the blanket does not meet the use requirements of consumers.

The photothermal response blanket is a functional household article capable of converting light energy into heat energy, and has the functions of near infrared ray and visible light absorption, heat energy storage control, temperature regulation and the like besides good photothermal response and comfort. The photothermal response blanket has a great difference in function with the heat storage and preservation blanket put out in the market at present. The heat-storage heat-preservation blanket is a new household article, the product is developed by mainly utilizing the characteristic that a special Phase Change Material (PCM) in heat-storage heat-preservation fibers can absorb or release heat when the temperature of the external environment changes, has good heat-storage heat-preservation performance, can not convert light energy into heat energy like a photothermal response blanket, and has the functions of near infrared ray and visible light absorption, heat energy storage control, temperature regulation and the like.

According to relevant literature search, no report of research and development application of the photothermal response blanket is found at home. The functional and fashionable household articles at any time adopt fine denier terylene DTY (draw textured yarn) and fine denier profiled terylene FDY (fully drawn yarn) as raw materials, and the photothermal response blanket produced by the special functional finishing agent is expected to become a necessary household bedding article and be widely applied.
