Problems solved by technology

[0014] The coating method is to use the coating processing method to mechanically bond the phase change material on the textile with an adhesive, which has the advantage of being simple and easy to implement; the current prior art is to directly mix the phase change material with the adhesive. Coated on textiles to make intelligent temperature-regulating textiles, however, because most phase change materials undergo phase change accompanied by the generation of a liquid phase, it will bring an oil-like appearance to the fabric when it absorbs heat and melts. negative impact, thereby reducing the wearing performance of products made by this method, and usually solve this problem by reducing the content of phase-change materials on the fabric, but this will also reduce the temperature-regulating effect of the fabric; the second is as patent No. CN200710057493.2 Invented by Tianjin University of Technology: a kind of intelligent temperature-regulating textile and its pr...

Abstract

The invention relates to an intelligent temperature adjustment textile and a making method thereof. The intelligent temperature adjustment textile is obtained through wrapping a phase change microcapsule by a coating adhesive, and coating the surface of a textile fabric. The above coating comprises 30-35wt% of the phase change microcapsule, 20-40wt% of an emulsion, 0.2-2wt% of a dispersant, 0.1-1wt% of an antifoaming agent, 2-8wt% of a thickener, 0.1-0.5wt% of a net removal agent and 20-30wt% of deionized water. The method comprises the steps of beating, pre-finishing, coating, baking and cooling rolling. The phase change material adopts the phase change microcapsule, so no oil immersion like negative effects of the fabric do not appear during endothermic melting; the textile adopting pint-like uniform coating has soft handle and good ventilating performance; and the temperature of a last stage hot air oven is controlled in a range of 150-180DEG C, so a cross-linking reaction of maleic anhydride and the phase change material is carried out, thereby the intelligent temperature adjustment textile coating has good fastness and water washing resistance.
