Abstract
Mixtures of microfibers and crimped bulking fibers produce a lofty resilient web having properties that are unique for microfiber-based webs. Included in these properties are a combination of high thermal resistance per unit of thickness and moderate weight, as well as other properties which give the web a distinctive utility as thermal insulation.
