Intelligent temperature adjusting viscose fiber and preparation thereof

The invention relates to intelligent temperature adjusting viscose fibers and a preparation method thereof. The intelligent temperature adjusting viscose fibers are prepared by addition of phase-transition microcapsules during the process of producing common viscose fibers, wherein, the compositions by weight percentage of the fibers are as follows: the content of completely dry fibers is between 84.7 and 92.85 percent; the content of the phase-transition microcapsules in the completely dry fibers is between 2 and 25 percent; the moisture content is between 7 and 15 percent; and the oil content is between 0.15 and 0.30 percent. The fibers inherit the superior characteristics of the viscose fibers and simultaneously have obvious functions of heat storage, heat liberation and bilateral temperature adjustment; the solidification and heat liberation enthalpy of the fibers delta H is more than 2.5 J/g, and the fusion and heat liberation enthalpy delta H is more than 2.5 J/g; and the fibers can be widely applied in
