Abstract
A composition for forming a filament including a blend of: (a) from 1 wt % to 40 wt % of a post-consumer recycled material having a density of from 0.910 g/cmto 0.940 g/cmand a melt index of from 1.0 g/10 min to 5.0 g/10 min; wherein the post-consumer recycled material consists essentially of (ai) from 30 wt % to 99 wt % of a linear low density polyethylene and (aii) from 1 wt % to 70 wt % of a low density polyethylene; and (b) from 60 wt % to 99 wt % of a virgin linear low density polyethylene; wherein the viscosity in pascal-seconds of the virgin linear low density polyethylene is no less than 0.5 times the viscosity of the post-consumer recycled material and no more than 2.0 times the viscosity of the post-consumer recycled material in the range of from 50 rad/s shear rate to 220 rad/s shear rate; a process for making the above filament composition; a filament made from the above filament composition; a process for producing the above filament; an artificial turf made from the above filament; and a process for manufacturing an artificial turf.
