Phase transition constant temperature cloth

The utility model discloses a phase transition constant temperature cloth, phase transition constant temperature cloth includes first cloth layer, sponge layer, first protective layer, phase change layer, second protective layer and second cloth layer, and wherein first cloth layer and second cloth layer do phase transition constant temperature cloth's surface and bottom surface layer, sponge level in first cloth layer below has first protective layer and second protective layer respectively with following above the phase change layer, and second cloth level is below the second protective layer. It is effectual that the phase transition adjusts the temperature adjusting the temperature of cloth, and the gas permeability is good, feels soft, and the phase change material dispersion is even and can not permeate the loss, and the washing fastness is good.
