The invention discloses a finishing technology of nano-grade phase-change microcapsule heat-accumulation temperature-adjustment intelligent textile fabric printed cloth. The nano-grade phase-change microcapsules are prepared according to certain steps and process conditions. The nano-grade phase-change microcapsules and the textile fabric printed cloth are cross-linked and finished, such that a finished product is obtained. The textile fabric is printed cloth of cotton, tencel, modal, blended cotton (viscose cotton, polyester cotton, polyamide cotton), silk, wool cotton, and the like. According to the finished nano-grade phase-change microcapsule heat-accumulation temperature-adjustment intelligent printed cloth, the encapsulation appearance of the nano-grade microcapsules is complete, an average particle size is 150nm, a shell thickness is 15nm, a core-shell volume ratio is approximately 1:1, peak phase-change temperatures are respectively 18-40 DEG C, and phase-change enthalpies are respectively 57-60J / g. The heating or cooling rate of the finished nano-grade phase-change microcapsule printed cloth is substantially retarded, such that the cloth has an intelligent temperature-adjustment function. Therefore, the cloth can be widely applied in outdoor clothes, underwear, sweaters, shirts, hats, gloves, and bedclothes, and provides a good effect.
