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