Stretchable nonwoven web and method therefor

A method for forming a nonwoven web comprising the steps of:

• melt spinning a plurality of continuous multiple component filaments comprising an elastomeric core component and a plurality of non-elastomeric permanently drawable wing components attached to the core and extending substantially continuously along the length thereof;
• quenching the filaments in a quench zone using a gas;
• passing the filaments through a gas jet, the jet gas providing draw tension to draw the filaments;
• and
• depositing the filaments onto a moving collector surface located below the gas jet to form a nonwoven web of multiple component filaments.

• quenching the filaments in a quench zone using a gas;
• passing the filaments in a single wrap alternately under and over at least two serpentine feed rolls;
• passing the filaments in a single wrap alternately under and over at least two serpentine draw rolls, the draw rolls being rotated at a surface speed that is greater than the surface speed of the feed rolls so that the filaments are drawn between the feed and draw rolls;
• passing the drawn filaments through a gas jet;
• and
• depositing the drawn filaments onto a a moving collector surface below the gas jet to form a nonwoven web of multiple component filaments.
