Abstract
In some embodiments, the inventive subject matter relates to a fiber construct suitable for use as a fill material for insulation or padding, comprising: a primary fiber structure comprising a predetermined length of fiber; a secondary fiber structure, the secondary fiber structure comprising a plurality of relatively short loops spaced along a length of the primary fiber. In some embodiments, the inventive subject matter relates to insulative fiber structures that mimic the structure and scale of natural down and thereby provide similar properties.
