METHOD FOR MAKING A CARPET HAVING A COATED SECONDARY BACKING

摘要

This invention relates to a method for making a carpet having a primary backing which is permeable to liquids and a secondary backing which is substantially impervious to liquids. The method involves applying a continuous coating of hydrophobic polymeric latex to the outer surface of a secondary backing material. The hydrophobic polymeric latex coating may be a modified latex containing fluorochemicals mixed therein.
