ABSTRACT:
An improved thermally insulating batt particularly designed for use as filling material for winter apparel, quilts, sleeping bags and the like, is produced by first preparing carded webs consisting of natural or synthetic fibers, plying several webs to form a batt, and then subjecting this batt to a subsequent resin treatment, on at least one face thereof, by using specific cross-linked glues. The resin treated batt is then calendered, under controlled temperature and pressure conditions, so as to obtain, on its surface, a soft, resilient and heat-sensitive film and, in the interior, an air chamber so as to provide a low thermal exchange coefficient and a proper control of the body temperature.
