Abstract
A method of producing a non-woven fabric having a high recovery after elongation and a substantially uniform surface including the steps of microcrepeing the fabric between about 20% and 35%, and heat setting the fabric to a temperature between its glass transition temperature and its melting temperature. A non-woven fabric having a recovery of at least 40% after five cycles of 35% elongation is made from a microcreped fabric of basis weight from 1-3.5 osy. The non-woven fabric has a uniform surface that is substantially free of bunching, gathering, and that is otherwise substantially flat to the eye and touch.
