Self-crimped ribbon fiber and nonwovens manufactured therefrom

摘要

Multi-component fibers or filaments that are ribbon shaped are provided having polymer components positioned in a side-by-side fashion. For example, the multi-component fibers may be bicomponent fibers having ribbon shape. The polymer components of the fibers are selected to have differential shrinkage behavior. Nonwovens are also provided that are manufactured from such ribbon shaped multi-component fibers or filaments.
