ABSTRACT:
A tufted pile fabric for use indoors or outdoors as a substantially permanent floor covering. The tufted pile fabric is made entirely from man-made or synthetic materials and includes a synthetic plastic primary backing, and a synthetic plastic secondary backing, laminated together by a hot melt adhesive to form a relatively rigid impervious sheet. The structure is then provided with a plurality of perforations through the substantially impervious sheet comprising the secondary backing, the hot melt adhesive and the primary backing to give the fabric a softer hand and breathability. The tufted pile fabric may then be adhesively secured to a floor structure by a water based adhesive, inert to the primary and secondary backings and hot melt adhesive, with the water evaporating through the perforations to set the adhesive and thereby avoid puckers and edge rippling due to unbonding the pile fabric from the floor structure.
