Heat preservation body structure using potential difference regulation to change fiber expansion

The present invention provides a heat preservation body structure using potential difference regulation to change fiber expansion mainly and respectively attaching the surface and lining layers of the inclined wrinkling cotton web plaited and formed from a long-fiber cotton net ribbon on the surface and lining clothes taking the non-woven cloth or cloth as the material so as to form the sandwiched structure similar to a bird's feather internally that containing eiderdown. By regulating the levelly potential differences or angles relative to the surface and lining clothes, the three-dimensional variation of fiber expansion of the wrinkling cotton web can be changed, thereby providing a heat preservation body structure suitable for different kinds of products, such as sleeping bags, bed quilts, skiing jackets, snowshoes, etc., and for sound insulation and heat insulation purposes and having better heat preservation effect.
