Abstract
Pillows and other filled articles are filled with bicomponent polyester fibers that have 'spiral crimp' on account of a difference in chain-branched content of the polyester polymers of the components. Such bicomponent fibers are preferably novel 'spiral crimp' bicomponent fibers that are hollow and/or are slickened.
