A soft-substrate carpet made from recycled yarns includes a carpet fiber layer and a recycled fiber layer in a top-to-bottom order, wherein the carpet fiber layer comprises carpet fibers and a first non-woven scrim, the carpet fibers being tufted on the first non-woven scrim, and the recycled fiber layer comprises recycled fibers and a second non-woven scrim, the recycled fibers being tufted on the second non-woven scrim; the carpet fiber layer and the recycled fiber layer are permanently bonded.

A dimensionally stable universal floor covering includes a tufted textile having stitches and a reinforcement layer operatively connected to the stitches to provide dimensional stability for the entire floor covering. The reinforcement layer is made of fibers that are initially contained within a composition of adhesive and fibers. Mixing of the adhesive/fibers composition and/or injection of compressed air, assists in preparing the adhesive and fiber composition to be in the preferred condition and position prior to the forming of the reinforcement layer. Multiple sources of pressure, including vacuum, are applied in a controlled manner for moving the adhesive and fiber composition to form a reinforcement layer of fibers that is operatively connected to the stitches and/or to form a layer of fibers and adhesive that is contained within the stitches. The universal floor covering is selectively cut and transported in a roll for installation, and it can be conveniently recycled if necessary.

The invention relates to an aqueous vinyl acetate-ethylene-copolymer dispersion for carpet coating compositions, which is obtained by means of radical-initiated emulsion polymerization, in an aqueous medium, of vinyl acetate and ethylene and optionally additional ethylenically unsaturated comonomers, characterized in that, for stabilization of the dispersion, 5 to 10 wt %, based on the total weight of the comonomers, of one or a plurality of partially saponified and low-molecular polyvinyl alcohols having a hydrolysis degree of 80 to 95 mol % and a Höppler viscosity, in 4% aqueous solution, of 1 to 5 mPas (method according to Höppler at 20° C., DIN 53015) are contained.

A soft-substrate carpet made from recycled yarns includes a carpet fiber layer and a recycled fiber layer in a top-to-bottom order, wherein the carpet fiber layer comprises carpet fibers and a first non-woven scrim, the carpet fibers being tufted on the first non-woven scrim, and the recycled fiber layer comprises recycled fibers and a second non-woven scrim, the recycled fibers being tufted on the second non-woven scrim; the carpet fiber layer and the recycled fiber layer are permanently bonded.

The invention comprises a method of making synthetic turf. The method comprises applying an ethylene-vinyl acetate copolymer adhesive to a first primary surface of a tufted primary backing to form a coating thereon and wherein the primary backing is tufted with a plurality of synthetic filaments to form a face pile extending outwardly from a second primary surface of the synthetic turf opposite the first primary surface and heating the ethylene-vinyl acetate copolymer adhesive to a temperature above its melting point so that the ethylene-vinyl acetate copolymer adhesive melts and at least partially flows into the primary backing. The method also comprises heating a linear low-density polyethylene film to a temperature below the softening point of the film and pressing the heated linear low-density polyethylene film into contact with the polymer coated first primary surface of the tufted primary backing. The method further comprises allowing the ethylene-vinyl acetate copolymer adhesive and the linear low-density polyethylene film to cool, whereby the linear low-density polyethylene film is adhered to the tufted primary backing.

The present invention relates to a composite comprising a nonwoven fabric being the substrate of the composite, wherein the nonwoven fabric comprises a polymer (A) selected from the group consisting of polyethylene, polypropylene, polyethylene terephthalate and polyamide; and a coating layer, wherein the coating layer comprises a polymer (B), wherein said polymer is an ethylene copolymer, preferably a polar ethylene copolymer; whereby the coating layer overlays at least one surface of the nonwoven fabric; and whereby the composite has a water vapor transmission rate (WTVR) according to ASTM E-96 ((water cup method) at 38° C. at 50% RH at the outside of the sample and 100% RH at the inside of the samples) of more than 50 g/[m.sup.2/24 h], preferably of more than 100 g/[m.sup.2/24 h].

A carpet tile includes a textile top member and a carrier mat that is coupled with the textile top member via a thermoplastic material. The textile top member includes carpet yarns and a backing that is coupled with the carpet yarns so that the backing structurally supports the carpet yarns. The carrier mat includes a polymeric material component, a reinforcement, and a binder that is uniformly distributed throughout the polymeric material component and reinforcement component. The polymeric material component includes polymer fibers that are randomly oriented and entangled together. The reinforcement is disposed within the polymeric material component so that the reinforcement is entirely covered and concealed by the entangled polymer fibers to prevent exposure to a user. The reinforcement mechanically reinforces and stabilizes the polymeric material component and carpet tile.

A method for forming an antimicrobial coating on a substrate is provided. The method comprises dissipating and entrapping (embedding) sulfonated copolymer particles in void spaces or interstices of fibers of a fabric forming an outer layer of a substrate. The sulfonated copolymer is selected from the group of perfluorosulfonic acid polymers such as sulfonated tetrafluoroethylene, polystyrene sulfonates, sulfonated block copolymers, polysulfones such as polyether sulfone, polyketones such as polyether ketone, sulfonated poly(arylene ether), and mixtures thereof. The fibers comprise a thermoplastic polymer having a melting point of less than 120° C., or 45-110° C., or 45-80° C. The sulfonated copolymer forms an antimicrobial coating layer for killing at least 90% microbes in the air within 30 minutes of contact with the coating.

The invention provides a flame retardant material comprising a substrate, an optionally corona-treated coating on the substrate, the coating comprising a polyolefin composition comprising a) an ethylene based plastomer with a density in the range of 0.857 to 0.915 g/cm.sup.3 and an MFR.sub.2 in the range 0.5-30 g/10 min; b) a propylene based plastomer with a density in the range of 0.860 to 0.910 g/cm.sup.3 and an MFR.sub.2 in the range 0.01-30 g/10 min; and c) a flame retardant, a primer layer on top of the coating and a lacquer topcoat.
