Abstract

A hydroformed expanded spun bonded nonwoven has a first substantially planar surface on one side thereof and a second surface on an opposite side thereof. The second surface includes a plurality of protuberances in a pattern. The hydroformed expanded spun bonded nonwoven web has an average loft of at least about 1.3 times greater than an original average loft of an original unexpanded spun bonded nonwoven web from which the hydroformed expanded spun bonded nonwoven web was created and an air permeability of at least about 1.2 times greater than an original air permeability of the original unexpanded spun bonded nonwoven web. The hydroformed expanded spun bonded nonwoven web includes bicomponent fibers combining a polymer with PLA in a ratio of polymer/PLA within a range of about 20/80 to 80/20.
