Abstract: The invention relates to nonwoven fabrics containing polymeric multiple component fibers which include a core component and a plurality of wing components attached to the core. The polymeric core component has an elasticity that is greater than the elasticity of at least one of the wing polymeric components. The fibers assume a spiral twist configuration in which the plurality of wings substantially spiral about the core. In a preferred embodiment, the nonwoven fabrics have elastic stretch and recovery properties with a textile-like hand.

Abstract: A method for preparing stretchable bonded nonwoven fabrics which involves forming a substantially nonbonded nonwoven web of multiple-component continuous filaments or staple fibers which are capable of developing three-dimensional spiral crimp, activating the spiral crimp by heating substantially nonbonded web under free shrinkage conditions during which the nonwoven remains substantially nonbonded, followed by bonding the crimped nonwoven web using an array of discrete mechanical, chemical, or thermal bonds. Nonwoven fabrics prepared according to the method of the current invention have an improved combination of stretch-recovery properties, textile hand and drape compared to multiple-component nonwoven fabrics known in the art.

Abstract: This invention relates to an improved method for preparing stretchable multiple-component bonded composite sheets which involves bonding a fibrous layer of spirally-crimpable multiple-component continuous filaments or staple fibers to one or more non-spirally-crimpable layers using an array of intermittent mechanical, chemical, or thermal bonds, and heating the bonded composite to activate the spiral crimp of the fibers in the spirally-crimpable layer. Multi-layer nonwoven fabrics prepared according to the method of the current invention have an improved combination of strength, aesthetics, stretch-recovery properties, and textile hand and drape compared to multiple-component nonwoven fabrics known in the art.
