Abstract

The invention relates to a temperature-sensing discoloring cloth which comprises a base cloth and a printing coating layer or a full-plate printing coating layer, wherein the printing coating layer or the full-plate printing coating layer is printed on the surface of the base cloth by color paste through a printing process; and a prescription of the color paste mainly comprises a solvent type polyurethane coating agent, at least two of dimethyl fomamide, butanone and toluene, a bridging agent and reversible temperature-sensing discoloring powder. The color and the luster of traditional fabrics are static, i.e. after being printed or dyed, the fabrics present unchanged color and luster or pattern; however, the invention can endow the fabrics with dynamic color and luster, i.e. the color and the luster of the printing layer are changed along with the change of the temperature, thereby improving the living standard of people and leading commodities to be more diversified.

Description

technical field [0001] The present invention relates to cloth, in particular to a temperature-sensitive color-changing cloth. The printing pattern printed on the base fabric of this kind of fabric is colored at low temperature. After the temperature is sensed, when the temperature rises to the discoloration point, the color of the printed pattern instantly becomes colorless or other colors. When the temperature drops below the discoloration point The printed pattern immediately returns to its original color at temperature. Background technique [0002] As we all know, cloth is an indispensable basic material for people to dress and decorate. For a long time, people have paid special attention to the decorative effect of fabrics, so printed fabrics with various color and pattern combinations emerge in an endless stream. Prints on traditional fabrics will only fade and not change color. With the advancement of science and technology, in order to pursue novel decorative effe...
