An artificial turf fiber comprising at least one monofilament, each monofilament comprising a cylindrical core and a cladding. The core comprises a core polymer and threadlike regions formed by a thread polymer and embedded in the core polymer. The cladding is formed by a cladding polymer surrounding the core. It has a non-circular profile and is miscible with the core polymer.

The present invention relates polyester tufted carpet where the tufts are engaged with a primary polyester backing and where a polyester extrusion coating is applied to the backside of the primary backing to lock the tufts which therefore avoids the use of a latex adhesive.

An artificial turf field system is provided. The system may include a plurality of synthetic turf strands attached to a backing layer and an infill material positioned between the synthetic turf stands. The infill material may include a plurality of porous particles. A sub-layer may be included beneath the backing layer, and may be formed of a resilient material. A support layer may be included beneath the sub-layer, and may include materials configured for drainage. The porous particles of the infill material may include porous ceramic particles and the sub-layer may include rubber. The porous particles may be at least partially coated, for example, by a polymer coating. The infill material may be free of sand and/or crumb rubber.

The present invention relates to an artificial turf. In the present invention, nylon is used as the main material. Through selecting straight fibers and curve fibers with certain cross-sectional shapes, lengths and widths and using the straight fiber and curve fiber together, the obtained grass fibers not only have relatively good temperature resistance, but also good handfeel, wear resistance, anti-aging performance, grass fiber resilience, trampling resistance and grass uprightness.

The invention provides for a method of manufacturing artificial turf (1000), The method comprising the steps of: —creating (100) a polymer mixture (100, 400, 500) comprising at least one polymer and a nucleat ing agent for crystallizing the at least one polymer; —extruding (102) the polymer mixture into a monofilament (606); —quenching (104) the monofilament; —reheating (106) the monofilament; —stretching (108) the reheated monofilament to form the monofilament into an artificial turf fiber (1004), wherein during the stretching the nucleating agent boosts the creation of crystalline portions of the at least one polymer within the monofilament; —incorporating (110) the artificial turf fiber into an artificial turf backing, thereby mechanically fixing the monofilaments of the arranged artificial turf fibers in the artificial turf backing.

The present invention pertains to a method for manufacturing a laminated textile product comprising providing a first intermediate product comprising a primary backing having a front surface and a back surface, and yarns stitched into the primary backing, the yarns extending from the front surface of the backing material, feeding the intermediate product along a body having a heated surface, the back surface being pressed against the said heated surface, to at least partly melt the yarns present in the intermediate product to bond the yarns to the backing, wherein the part of the back surface that is pressed against the heated surface has a relative speed with respect to the heated surface, so as to provide a second intermediate product having a calendered back surface, providing a dimensionally stable carrier sheet or secondary backing, and connecting the second intermediate product to the carrier sheet by providing a hot melt adhesive between the calendered surface and the sheet, and pressing the sheet to the second intermediate product to form the textile product.

A method for manufacturing an artificial turf fiber includes creating a polymer mixture that includes, 60-99% by weight of an LLDPE polymer and 1-15% by weight of an LDPE polymer. The method further includes extruding the polymer mixture into a monofilament; quenching the monofilament; reheating the monofilament; and stretching the reheated monofilament to form the monofilament into the artificial turf fiber.
