    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.

    Abstract: Improvements in preventing heat- and moisture-shrink problems in specific polypropylene tape fibers are provided. Such fibers are basically manufactured through the initial production of polypropylene films or tubes which are then slit into very thin, though flat (and having very high cross sectional aspect ratios) tape fibers thereafter. Such fibers (and thus the initial films and/or tubes) require the presence of certain compounds that quickly and effectively provide rigidity to the target polypropylene tape fiber after beat-setting. Generally, these compounds include any structure that nucleates polymer crystals within the target polypropylene after exposure to sufficient heat to melt the initial pelletized polymer and upon allowing such a melt to cool. The compounds must nucleate polymer crystals at a higher temperature than the target polypropylene without the nucleating agent during cooling. In such a manner, the nullrigidifyingnull nucleator compounds provide nucleation sites for polypropylene crystal growth. Upon slitting of the initial film and/or tube, the fiber is then exposed to sufficient heat to grow the crystalline network, thus holding the fiber in a desired position. The preferred nullrigidifyingnull compounds include dibenzylidene sorbitol based compounds, as well as less preferred compounds, such as sodium benzoate, certain sodium and lithium phosphate salts (such as sodium 2,2null-methylene-bis-(4,6-di-tert-butylphenyl)phosphate, otherwise known as NA-11). Specific methods of manufacture of such inventive tape fibers, as well as fabric articles made therefrom, are also encompassed within this invention.
