In this study, nano-cool fiber membranes were prepared by electrospinning in the solution of PVA, and the effects of xylitol ratio on the cold sensation were investigated. The effects of the ratio of xylitol on the cold sensation were observed by electron microscopy. The fineness of the fineness of the fiber. From the results of the study, the addition of xylitol will make the fiber fineness larger, fineness range of 0.18-0.68μm, and make the composite film coolness rise. When the ratio of xylitol to water is 8:2, the thermal conductivity is the best
