ABSTRACT:
Lofty battings are prepared by a process involving carding to make one or more webs of fibers, preferably using a blend of mechanically-crimped filling fibers with bicomponent fibers of helical configuration, and that preferably also contains binder fibers, the fiber orientations preferably being randomized in the web(s) before cross-lapping to build up the batt, and preferably followed by spraying with resin and curing, thus providing a bonded batt in which the loft is improved by the presence or the different crimp configurations and/or randomized orientations that are fixed in the fibers in the bonded batt.
