NOVELTY - Composite phase change temperature regulating material, comprises a phase change energy storage microcapsules and phase change energy storage aerogels dispersed in a dispersant; where the core material of the phase change energy storage microcapsules is n-hexadecane or N-heptadecane, and the material of the capsule wall is gelatin and gum arabic; the phase change energy storage aerogel includes graphene aerogel and a phase change compound adsorbed in the pores of the graphene aerogel, and the phase change compounds include n-nonadecane, n-eicosane or n-eicosane. USE - The multiple phase-change temperature-adjusting fiber is useful in textiles (claimed). DETAILED DESCRIPTION - INDEPENDENT CLAIMS are also included for: (1) preparation of the composite phase change temperature regulating material, comprising: providing phase change energy storage microcapsules and phase change energy storage aerogels, combining the phase change energy storage microcapsules and phase change energy storage aerogels, and dispersing the capsule and the phase change energy storage aerogel in the dispersant; (2) multi-phase-change temperature-regulating fiber, comprising cellulose fiber and a composite phase-change temperature-regulating material, where the phase-change energy storage aerogel in the composite phase-change temperature-regulating material is adsorbed in the pores of the cellulose fiber, and the phase change energy storage microcapsules in the composite phase change temperature control material are cross-linked with cellulose fibers; and (3) preparing the multiple phase change temperature-regulating fiber, comprising mixing cellulose fiber spinning dope, denaturant, polyethylene glycol and composite phase-change temperature-regulating material to obtain a blended spinning fiber original solution, spinning and crosslinking the blended spinning dope to obtain the multiple phase change temperature-adjusting fiber.
