ABSTRACT:
Wet steam or hot water treatment of a secondary backing just before application to an aqueous adhesive coated back of a carpet or rug such as a tufted carpet containing a primary backing provides on drying and curing of the laminate an increase in many instances in the dry and wet strength of the secondary backing to the primary backing and some reduction in the time of drying or curing of the adhesive to bond the laminate together.
