Abstract
Nonwoven fabrics having a desirable level of bulk, elasticity and low permanent set are produced by creasing a precursor web and heat setting the creases. Such webs may have varying basis weights and compositions depending on the intended end use. Applications disclosed include components for personal care products such as disposable diapers and feminine hygiene products, for example, as well as garment applications such as training pants, surgical gowns and the like. Also, absorbent products such as wipers are disclosed. Methods for forming the creased nonwoven fabric are disclosed using interdigitated rolls for creasing in the machine direction or in the cross-machine direction.
