ABSTRACT:
This invention relates to methods for making a carpet having a secondary backing which is substantially impervious to liquids. The methods involve applying a repellent finish onto the secondary backing material and drying the finish. The finish may be applied as foam to the secondary backing, against the force of gravity, by means of a press roll. This invention also includes the resultant carpets prepared from these methods.
