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.times.10.sup.-10 in..sup.4 to 8.33.times.10.sup.-9 in.sup.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.
Claims18
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.times.10.sup.-10 in..sup.4 to 8.33.times.10.sup.-9 in..sup.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.

An artificial grass product, comprising:
- a pile fabric with yarn comprised of a single fiber 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.times.10.sup.-10 in..sup.4 to 8.33.times.10.sup.-9 in..sup.4, the yarn tufted into a backing to form successive rows of loops of the fiber which are cut to provide a cut-pile face.
