Abstract

The invention relates to a multi-segment thermochromic temperature-regulating fabric. A temperature change pigment, phase-change temperature regulating microcapsules, auxiliaries and water are prepared into color paste, and then the color paste is continuously printed on a fabric by use of a flat screen or rotary screen printing process to form a textile having double effects of heat discoloration and temperature regulation. The multi-segment thermochromic temperature-regulating fabric can be widely applied to knitwears, woven products and non-woven products. The temperature change pigment is capable of changing colors by a plurality of segments, and the change of different patterns can be realized in the color change process due to the design of the printing process. The multi-segment thermochromic temperature-regulating fabric is capable of achieving the thermochromic fashionable or warning effect, and also capable of achieving the two-way regulation and delaying effects of temperature regulation, and is wide in market application prospect.

Description

technical field [0001] The invention relates to functional fabrics, in particular to a textile with dual functions of multi-stage temperature-sensing color change and temperature adjustment. Background technique [0002] With the advancement of science and technology, the functionalization, differentiation and fashion of textiles have become a trend. At the same time, the high added value of functional textiles has become a new economic growth point for my country's textile industry. Due to the continuous deepening of the research on the function of textiles, the application fields of functional textiles have also been continuously expanded. In addition to the traditional application fields such as clothing and home textiles, the application of textiles with different functions has extended to all aspects of people's production and life. [0003] Invention patent CN201210239380.5 discloses a coating slurry composition for heat-sensitive discoloration and energy storage texti...
