(57) [Abstract] Non-stretched, tough, durable, melt-bondable macrodenier thermoplastic plastic multi-component filaments, such as core-sheath and bonded filaments, consist of all material / air boundaries of the filaments, Or comprising a first plastic component and a second plastic component defining at least a portion. These filaments are formed by melt extruding a thermoplastic to form the hot filaments, cooling and solidifying the hot filaments, and collecting the solidified filaments without any tension thereon. Can be manufactured by Filament aggregates can be manufactured in the form of floor mats or abrasive articles. |
