Intelligent temperature adjustment textile and making method thereof

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.

Description

technical field [0001] The invention relates to an intelligent textile and a preparation method thereof, in particular to an intelligent temperature-regulating textile and a preparation method thereof. Background technique [0002] With the improvement of people's living standards, people's requirements for clothing have gradually changed from simple warmth retention to the pursuit of functionality and comfort. Among them, the successive appearance of anti-static, flame-retardant, waterproof and other functional textiles has greatly It has promoted the development of textile finishing technology. With the continuous expansion of research fields and the continuous development of textile processing technology, people have a new understanding and understanding of the most basic function of keeping warm and cold in clothing; organically integrating fashion, beauty and clothing warmth The intelligent temperature-regulating textiles produced by using modern high-tech textile proce...

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 preparation method, hydrolyzing and polymerizing tetraethyl orthosilicate, absolute ethanol and distilled water at room temperature into silica network structure gel, and then adding alcohol phase The composite phase change material made of changing materials, and finally the composite phase change material is mixed with an adhesive and coated on the surface of the textile fabric to make a smart temperature-adjusting textile; this method effectively activates the phase change material through the gel. Wrapping, and then using adhesives to mechanically bond the phase change material to the textile, solves the negative impact of the oil-like appearance of the fabric when the endothermic melting occurs. However, since the coating is scraped Pulp is formed, so the air permeability is poor, and there are problems with the fabric feel and the stability in use. The smart temperature-adjusting textiles made have poor wearability and limited uses, and have not been popularized so far.
