Abstract
A stitchboard material including an elastomeric nonwoven fibrous web, e.g., an elastomeric web of meltblown fibers, and method of forming the material, is disclosed. The material, including the elastomeric web, is stretchable and has breathability, and avoids holes through the material at the location where the stitches pass through the material. The elastomeric web can be used in combination with elongatable or gatherable webs of fibrous material to provide stitchbonded stretchable composite fabrics having desired stretch and surface characteristics, and breathability, useful as fabric for wearing apparel (e.g., stretch corduroy) or other textile uses such as draperies and other home furnishings.
