BIOMIMIC DESIGN OF MULTI-SCALE FABRIC WITH EFFICIENT HEAT TRANSFER PROPERTY

Abstract

Wool fiber has a complex hierarchic structure. The multi-scale fibrils are assembled o form a tree-like channel net in wool fiber, providing an efficient heat ransfer property. The optimal inner configuration of wool fiber can also be invited o biomimic design of textile fabrics to improve the thermal comfort of loth. A heat transfer model of biomimic multi-scale fabric using the fractal derivative s established. Theoretical analysis indicates that the heat flux efficiency n the biomimic fabric can be 2 orders of magnitude comparing with that of the ontinuous medium.
