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.
