Abstract
Crimped foamed fibers are produced by a process which eliminates any mechanical deformation steps. The process comprises the step of forming foamed fibers having a plurality of randomly arranged cells distributed asymetrically over a given cross section and occupying at least about 10% of the cross sectional area of the fiber, and heating the foamed fibers while maintaining the fibers under no load condition to produce a crimped foamed fiber. The crimped foamed fibers are used in apparel, carpet fibers, thermal insulation, acoustic and filtration.
