Stretchable composite sheets and processes for making

Image Number 3 for United States Patent #7005395.

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.
