The invention comprises a method of making synthetic turf. The method comprises applying a plurality of solid polyethylene polymer particles to a tufted primary backing of a tufted synthetic turf to form a coating thereon, wherein the solid polyethylene polymer particles have an average particle size of approximately 1 to approximately 1,000 microns and a melt index of approximately 50 to approximately 500 grams/10 minutes at 190&#xb0; C. at a weight of 2.16 kg. and wherein the primary backing is tufted with a plurality of synthetic filaments to form a plurality of synthetic filaments extending outwardly from the side of the synthetic turf opposite the primary backing. The method also comprises heating the solid polyethylene particles to a temperature above their melting point so that the solid polyethylene polymer particles melt and at least partially flow into the primary backing and cooling the polyethylene polymer on the primary backing. A product made by the foregoing process is also disclosed.

Scatter coating process for synthetic turf and product

The invention comprises a method. The method comprises applying a composition to a tufted primary backing material, wherein the primary backing material has a first primary surface and a second primary surface, wherein tufts extend outwardly from the first primary surface and loop backs are formed on the second primary surface, and wherein the composition is applied to the loop backs and second primary surface of the tufted primary backing material. The composition comprises an aqueous polymer dispersion of colloidal thermosetting polymer particles or colloidal thermoplastic polymer particles and second thermoplastic polymer particles dispersed in the water, wherein the second thermoplastic polymer particles have an average particle size of approximately 200 micron to approximately 1,000 microns. The method further comprises heating the tufted primary backing material and aqueous polymer dispersion to remove water therefrom. A novel adhesive composition is also disclosed.

Aqueous polymer dispersion composition and method of adhering textile materials

The invention comprises a method. The method comprises applying a quantity of an aqueous dispersion of thermoplastic polymer particles to a primary backing and loop backs of a tufted carpet or a tufted synthetic turf, wherein the thermoplastic particles have an average particle size less than 1,000 microns. The method also comprises heating the aqueous dispersion to a temperature sufficient to remove water therefrom, and heating the thermoplastic particles on the primary backing and loop backs to a temperature at or above the melting temperature of the thermoplastic particles. The method further comprises allowing the heated thermoplastic polymer particles to cool below their melting temperature whereby the loop backs are adhered to the primary backing.

Method of applying a theromplastic polymer coating

A method and apparatus for purifying and recycling synthetic turf are provided. The method includes removing a section of used synthetic turf, feeding the section to a rotating beater to knock sand infill loose, and passing the section through a rotating brush roll wherein a turf filament surface is directly contacted by the rotating brush roll to knock any entrained infill material loose from the section of used synthetic turf.
