Abstract: Embodiments of the present disclosure are directed to stretched filaments comprising a non-functionalized polyolefin and at least one functionalized polymer. The functionalized polymer is a propylene-based plastomer or elastomer having one or more functional groups grafted on the propylene-based plastomer or elastomer. The one or more functional groups is selected from the group consisting of amine groups and imide groups. The at least one functionalized polymer has a DSC melting point from 100° C. to 130° C. When the stretched filament is stretched to a stretch ratio of 5, the stretched filament has a tenacity greater than 0.90 cN/dtex

Abstract: Artificial turf system (10) including a primary backing layer (12) and a shock absorption component (20). The primary backing layer (12) has a plurality of artificial turf yarns (14) projecting upwardly from the primary backing layer (12). The shock absorption component (20) is composed of a sheet of three-dimensional random loop material 3DRLM (30). The sheet of 3DRLM (30) is in contact with the primary backing layer (12). The shock absorption component (20) includes (i) a cushioning layer (40) and (ii) a shockpad (50). The 3DRLM (30) in the cushioning layer (40) has an apparent density that is greater than the apparent density of the 3DRLM (30) in the shockpad (50).
