Abstract
A flock material exhibiting an increased degree of filament separation prepared by cutting a fluoropolymer or carbon fiber yarn into lengths, introducing mechanical energy into the lengths in order to cause the lengths to separate into single-filaments fibers and removing or classifying at least a portion of the single-filament fibers from the lengths in order to obtain a flock having a particular fraction of single-filament, fluoropolymer or carbon fibers.
