Abstract:
1. A fiber aggregate comprising organic polymeric fibers, wherein at least 50 percent by volume of fibers present in the fiber aggregate are the organic polymeric fibers, wherein the organic polymeric fibers have an average length in a range from 2 to 20 millimeters, an average diameter up to 100 micrometer, and comprise at least 75 percent by solid volume of the fiber aggregate, wherein up to 80% by number of the organic polymeric fibers have an acute included angle not greater than 20°, wherein the fiber aggregate has an unrestrained bulk density of at least 0.05 g/cm 3 and wherein at least 85% by solid volume of the fiber aggregate disassociates to provide dispersed fibers according to The Aggregate Disassociation Test.
