ABSTRACT:
Polyester fiberfill having spiral crimp that is randomly-arranged and entangled in the form of fiberballs with binder fibers, preferably with a minimum of hairs extending from the surface of the fiberballs, so as to be air-transportable on account of the low cohesion between the balls. A process for making such fiberballs by repeatedly air-tumbling small tufts of such fiberfill/binder/blend against the wall of a vessel. Improved bonded batts or molded articles or other bonded articles obtained by bonding such fiberballs.
