    Abstract: A carpet structure and backing of superior dimensional stability and integrity which is especially useful in a free float system of installation. In one aspect of the invention, a carpet is provided having a selected dimensional stability in which there is (i)a first carpet part having a primary layer with pile substantially covering a first side of the layer, the pile tufted through the primary layer to leave tuft bundles on a second side of the primary layer and a binder encapsulating the tuft bundles, the first part having a predetermined force of expansion and contraction under cycling conditions of temperature and moisture; (ii) a second part in layered relationship to the first carpet part, the second carpet part constructed from one or more layers to have a predetermined resistance to expansion and contraction at least equal to or greater than the force of expansion and contraction of the first carpet part under cycling conditions of temperature and moisture and traffic loads on the carpet pile.

    Abstract: A modified secondary backing fabric (20) for carpet (50) comprises a secondary backing scrim fabric (15) and a fiber batt (21) integrated with the secondary backing fabric forming the modified fabric, providing a soft face (51) opposite the face (52) presented by the scrim fabric, uninterrupted by the scrim fabric. A carpet (50) comprises a face yarn (11); a primary backing fabric (12), the face yarn being tufted into the primary backing fabric; a modified secondary backing fabric (20) attached to the primary backing fabric; and an adhesive material (14) binding the face yarn to the primary backing fabric and the primary backing fabric to the secondary backing fabric. The modified secondary backing fabric (20) comprises a secondary backing scrim fabric (15) and a fiber batt (12) integrated as a unitary scrim, providing a soft face (51) forming the underside of the carpet, the soft face forming a barrier uninterrupted by the scrim fabric and blocking exudation of any of the adhesive material from the underside of the carpet. A method for the manufacture of a modified secondary carpet backing (20) comprises selecting a secondary backing scrim fabric (15) and a fiber batt (21); joining the two fabrics to form the modified secondary carpet backing (20), providing a soft face (51) opposite the face (52) presented by the scrim fabric, uninterrupted by the scrim fabric; and subjecting the modified fabric to heat sufficient to remove substantially all loose fibers (45) projecting from the soft surface. The present invention also provides a method for the manufacture of carpet.

    Abstract: This invention relates to a novel modular carpet tile mat construction and a process of making same. More particularly, the invention relates to a novel modular carpet tile mat construction which is specifically adapted to hold carpet tiles in a fixed position so that they may be used in combination as a floor mat or a covering for part of a floor area, or a self-contained floor covering. A mat base composed of woven or spun-bonded polyester, nylon or polypropylene fibres comprising: (a) a woven or spun-bonded polyester, nylon or polypropylene fibre mat; (b) a plastic binder enveloping the fibre mat and binding the fibres of the mat together to provide a first side on one side of the plastic-enveloped woven or spun-bonded fibre mat and a second side on an opposite side of the plastic-enveloped woven or spun-bonded fibre mat; (c) a first layer of resilient expanded or foamed polymer or rubber distinct from the plastic binder (b) and adhered to the first side of the plastic-enveloped woven or spun-bonded fibre mat; and (d) a second layer of resilient expanded or foamed polymer or rubber distinct from the plastic binder (b) and adhered to the second side of the plastic-enveloped woven or spun-bonded fibre mat.
