Abstract:
1. A three-dimensional, cuspated profile, turf reinforcement mat comprising trilobal, thermoplastic polymer, filament yarn wherein the trilobal, thermoplastic polymer, filament yarn includes a cross-sectional geometry having a substantially circular core region and three substantially convex elongated lobes that are substantially equally spaced around the core region, each elongated lobe consisting of a single, substantially symmetrical half-ellipse shaped convex member disposed along a portion of the circumference of the core region, a shortest distance between a geometrical apex of the convex member and the portion of the circumference of the core region being substantially equal to a longest width of the convex member along a geometrical axis perpendicular to a geometrical axis defined by the shortest distance between the apex and the portion of the circumference of the core region, and three substantially concave and smoothly curved channels separating the elongated lobes, a portion of each smoothly curved channel comprising a plurality of points along the circumference of the core region wherein the trilobal, thermoplastic polymer, filament yarn is woven to form a generally planar mat wherein the generally planar mat is subject to heat of a temperature and duration sufficient to accentuate a three-dimensional, cuspated profile.
