摘要：
This invention relates to methods for making a carpet having a secondary backing which is substantially impervious to aqueous solutions. The process involves applying a fluorochemical onto the underside of a secondary backing material, followed by drying and curing of the fluorochemical. This invention also includes the resultant carpets prepared from such a process.
