Abstract
The present invention pertains to a process and product thereof, and an apparatus, for converting a twisted, continuous filament, multifilament yarn into a staple-like yarn. The process is carried out by needling the yarn with a barbed needle in order to break yarn filaments. The broken yarn filaments protrude from the yarn after the needling process. The protruding filament ends give the resulting yarn the appearance of a spun yarn.
