Goose down has superior thermal insulating properties as a filler material used widely as
an insulator in textile products. Its particular “tree” structure is expected to attribute greatly
to this insulating property. In this paper, fractal structures of the down “tree” are observed
using scanning electron microscopy (SEM), and the configuration characteristics of goose
down are described quantitatively by local fractal dimensions. From two expects, the local
fractal dimensions were calculated both theoretically and experimentally, revealing its value
to be very close to the golden mean, 1.618. This near-optimal fractal dimension may be
attributable to the excellent thermal insulation of goose down assembly, and the potential
applications of such a fractal structure are also discussed.
