    摘要： This invention concerns a method for stabilizing polarized polymeric piezoelectric films wherein a polarized polymeric piezoelectric film is exposed to an electric field of reverse polarity to that employed in the polarization step for a period sufficient to remove unstable homo- and hetero-charges but insufficient to depolarize useful charges in the final film.

    摘要： The present invention relates to tufted goods comprising a greige good having fibers tufted into a primary backing, a precoat which is adhered to the back surface of the greige good, and a flexible film which is laminated to the back surface of the precoat. The flexible film is treated via corona-discharge prior to being laminated to the precoat. This invention also relates to a process for producing tufted goods. This process comprises treating a flexible film via corona-discharge, contacting the treated flexible film with the uncured or partially cured back surface of a precoated greige good, and curing the article. Optional embodiments of this invention include having a foam layer between the precoat and the flexible film, or having a foam layer on the back surface of the flexible film. An alternate embodiment of this invention comprises substituting a foam layer for the precoat.

    摘要： 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.
