Abstract
An elasticized non-woven fiber material is made by combining one or more textile fibers with one or more elasticizeable fibers and bonding the combined fibers together. The resultant web of bonded non-woven fibers is then heat-treated to heat-shrink the elasticizeable fiber and recover its elasticity thereby shrinking the fibers and the web of material. An elasticized non-woven fabric made by the described method is also provided.
