Composite fabric with heat-accumulation temperature-adjustment phase-change materials as well as preparation method and application thereof

Abstract

The invention discloses a compound fabric with heat-accumulation temperature-adjustment phase-change materials as well as a preparation method and the application thereof. The composite fabric consists of three layer, phase-change materials PEG are extruded into a thin film by a threaded rod, then two PE films are compounded on and under the thin film to be extruded into a three-layer compound film, and then both ends of the three-layer compound film are cut to seal edges according to different needs of bedclothes or clothes packing courses. The compound fabric has the heat-accumulation temperature-adjustment effect of the phase-change materials, thereby having functions such as absorption, storage and release of heat energy; and in addition, the compound fabric is a novel compound fabricand is especially suitable for being used as the bedclothes and constant temperature clothes for babies and old and weak patients.

Description

technical field

[0001] The present invention relates to a multi-layer polymer film and fabric composite fabric and its preparation method and application, more particularly, to a composite fabric with heat storage and temperature adjustment phase change material and its preparation method and application.
