Abstract:

The present invention relates to an improved process for the production of artificial turf, and the improved artificial turf. In accordance with this process, fibers are treated via corona discharge, tufted into a primary backing to form a greige good, and a precoat is applied to the back surface the greige good. Suitable fibers are polyolefins, and suitable precoats are reactive polyurethane mixtures. The fibers may be treated by corona discharge either before they are tufted into the primary backing to form the greige good or after the are tufted into the primary backing. Artifical turfs of the present invention comprise a greige good having fibers tufted into a primary backing, with the fibers being treated by corona discharge either before or after being tufted into the primary backing, and a precoat which is attached by its face surface to the back surface of the greige good.
