<p>The method involves deforming fiber sections of polymer fibers such as thermoplastic fibers e.g. polyethylene fibers or polypropylene fibers, with length ranging from 0.1-50 cm to form pourable particles. The fiber sections are directly cooled with liquid nitrogen before the deformation process such that a work is assisted to change physical characteristics i.e. molecular weight, of the polymer and to not to thermally decompose the fiber sections. Wheels or disks rotated relative to each other are arranged on rings. Independent claims are also included for the following: (1) a device for deforming fiber sections of polymer fibers (2) pourable particles made according to a producing method.</p> |
