Method of delaying and reducing texture reversion of a textured artificial turf yarn

A method of creating an artificial turf infill comprising providing olive pit fragments from an oil extraction process employing compressing the olives for extracting the olive oil, and tumbling the olive pit fragments to smoothen sharp edges of the olive pit fragments to produce rounded olive pit fragments.

Method for making artificial turf infill with rounded olive pit fragments

A synthetic turf () includes a plurality of synthetic turf fibers () knitted together to form a knitted backing layer () of the synthetic turf, and a water permeable polyurethane coat () formed on the knitted backing layer.

Synthetic turf with high drainage and manufacturing thereof

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.

Artificial turf fiber with a non-circular cladding

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.

Artificial turf fiber with LLDPE and LDPE

A method of manufacturing an artificial turf includes creating fluid polyurethane mass. The creation including reacting first and second polyols with an isocyanate. The first polyol is a polyether polyol and/or a polyester polyol having at least 2 hydroxyl groups per molecule, the second polyol being polybutadien diol. The isocyanate including isocyanate monomers, isocyanate polymers or isocyanate prepolymers or a mixture thereof, the isocyanate monomers, isocyanate polymers and the isocyanate prepolymers having two or more isocyanate groups per molecule. The method further includes incorporating an artificial turf fiber into a carrier such that a first portion of the fiber protrudes to the front side of the carrier and that a second portion of the fiber is located at the back side of the carrier, adding the fluid polyurethane mass on the back side of the carrier, and hardening the fluid polyurethane mass.

The invention relates to a completely or partially compostable turf () the turf being a completely or partially compostable artificial turf or a hybrid turf () comprising a completely or partially compostable hybrid turf support, the turf comprising a decomposition inhibitor, the decomposition inhibitor in the turf being adapted to lose its functionality or leave the turf until a defined period of time has elapsed.

Compostable turf with decomposition inhibitor

A method of manufacturing artificial turf creating a liquid polymer mixture, wherein the polymer mixture is at least a two-phase system. A first one of the phases includes a first polymer and a first dye, and a second one of the phases of the polymer mixture includes a second polymer and a second dye. The second dye has a different color than the first dye, the second polymer being of the same or of a different type as the first polymer. The first and the second phase are immiscible, the first phase forming polymer beads within the second phase. The method further includes extruding the polymer mixture into a monofilament including a marbled pattern of the first and second color; quenching the monofilament; reheating the monofilament; stretching the reheated monofilament to deform the polymer beads into threadlike regions and to form the monofilament into an artificial turf fiber; and incorporating the artificial turf fiber into an artificial turf backing.
