▎ 摘  要

NOVELTY - Preparing bistable multi-stimulus responsive Janus color-changing fibers comprises (1) dissolving the sodium alginate in water to obtain spinning mother liquid, (2) taking part of the spinning mother liquid and thermochromic microcapsule, uniformly mixing to obtain the bistable thermochromic spinning solution, recording Janus A spinning solution, taking the other part of spinning mother liquid and functional nanometre material, mixing uniformly to obtain the spinning liquid with photo-thermal and electric heating conversion function, recording Janus B spinning liquid, and (3) allowing to stand and defoaming the Janus A spinning liquid, Janus B spinning liquid, respectively installing in the two syringes, injecting two syringes into the coagulation bath through the same pinhole to prepare the bistable multi- stimulus responsive Janus color-changing fibers. USE - The fiber, the color-changing yarn, and the color-changing fabric are useful for preparing intelligent textiles (claimed). ADVANTAGE - The fiber has light, heat, electric triple stimulus response and double stability, and effectively solves the problem that the color of the color-changing fiber is affected by the dark color of the functional nano material. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are also included for: a bistable multi-stimulus responsive Janus color-changing fibers, prepared as above-mentioned method; a color changing yarn, obtained by spinning the bistable multi- stimulus responsive Janus color-changing fiber; and a color changing fabric, obtained by weaving the bistable multi-stimulus responsive Janus color-changing fiber or the color-changing yarn.
