摘要： The present invention relates to a fabric, such as a backing suitable for tufted carpets or artificial turf, comprising slit films, tapes or monofilaments, said slit film, tape or monofilament comprising at least 70% by weight of a metallocene-catalyzed polyethylene composition based on the total weight of the slit film, tape or monofilament. The metallocene-catalyzed polyethylene composition comprised in the slit film, tape or monofilament is a metallocene-catalyzed polyethylene composition comprises: a) at least 45% by weight based on the total weight of the metallocene-catalyzed polyethylene composition of a metallocene-catalyzed polyethylene A, wherein said metallocene-catalyzed polyethylene A has a density of at most 0.918 g/cm3, and a melt index MI2 of at most 4.0 g/10 min; and b) at least 25% by weight based on the total weight of the metallocene-catalyzed polyethylene composition of a metallocene-catalyzed polyethylene B, wherein said metallocene-catalyzed polyethylene B has a density which is higher than the density of said metallocene-catalyzed polyethylene A; and a melt index MI2 which is higher than the melt index MI2 said metallocene-catalyzed polyethylene A. The invention further relates to processes for manufacturing said fabric, such as processes for manufacturing a backing suitable for artificial turf, processes for manufacturing the slit film, tape or monofilament and to articles, e.g. a (woven) fabric, comprising said slit film, tape or monofilament obtained by said processes.
