Why is down soft and lofty?
Tuesday, November 17, 2009
Ducks and geese have soft insulating down clusters on their breasts. Down is a plume, which means that it has no hard elements such as a quill like feathers have. Down clusters contain many thousands of soft filaments that radiate out like a dandelion and form the spherical plume.
Down has a structure that is three-dimensional that gives it superior lofting and fill power. A goose down pillow is incredibly soft and luxurious because of the loft of down.
