Tuft and filament binding in unfinished carpet

摘要

A process for tuft and filament bonding of unfinished carpet includes applying a coating composition which contains from 50% to 100% by weight of a substantially amorphous poly-alpha-olefin as a melt to the backside of a carpet material so as to obtain a coating weight of from 20 to 1,500 g/m², the melt viscosity of the coating composition at 190° C. is in the range from 400 mPas to 10,000 mPas.
