Abstract
Abstract An artificial grass product with pile fibers having a modulus of elasticity of from 25,000 p.s.i. to 100,000 p.s.i. and a moment of inertia of from 1.06×10 -10 in. 4 to 8.33×10 -9 in 4 . For fibers of rectangular cross-section the fiber dimensions range from 0.004 in. to 0.010 in. in thickness and 0.020 in. to 0.100 in. in width.

Claims Analysis
Total Claims: 20
Claim 1
Independent Claim
103 words
An artificial grass product, comprising: a pile fabric with yarn comprised of a plurality of fibers made of a polymeric material selected from the group consisting of copolymers of ethylene-vinyl acetate, ethylene-ethyl acrylate, ethylene-butylene, ethylene-propylene; polyvinyl chloride; chlorinated polyolefins; low density polyethylene; and mixtures thereof and having an elastic modulus of from 25,000 p.s.i. to 100,000 p.s.i. and a moment of inertia of from 1.06×10 -10 in. 4 to 8.33×10 -9 in. 4 , the fibers extending from and substantially perpendicular to a backing to which the fibers are secured, wherein the yarn is twisted at the point of emergence from the backing.
Claim 2
Dependent Claim
103 words
