Uses for microfiber-based webs
Abstract
Microfiber webs and composite webs comprising blends of microfibers and crimped bulking fibers have a variety of uses, including use as thermal insulation for garments as well as various structures such as buildings, tents, refrigerator cabinets, or window shades; acoustic insulation; light weight fillers; various structural members, such as battery separators; filters; and applicators, cloths and wipes. For these and other uses the webs may be combined with other articles such as films or fabrics or other kinds of insulating or lofty webs.
