    摘要： The invention provides for a method of manufacturing an artificial turf fiber (710). The method comprises creating (502) a liquid polymer mixture (100, 200, 300, 400). The polymer mixture comprises a base polymer (102), plastic waste comprising one or more aged polymers (106, 302, 304), and a compatibilizer (104). The one or more aged polymers comprise an IM polymer (106, 302) that is not miscible with the base polymer. The base polymer is an unaged polymer. The liquid polymer mixture is a multi-phase system. The compatibilizer emulsifies the IM polymer within the base polymer such that the IM polymer forms polymer beads surrounded by the compatibilizer within the base polymer. The method further comprises extruding (504) the polymer mixture into a monofilament (606) and fabricating the artificial turf fiber from one or more of the monofilaments.

    摘要： A coextrusion head for manufacturing a bicomponent polymer fiber, comprising a first inlet for receiving a core polymer component (206), a second inlet for receiving a cladding polymer component (204), and a dual-channel nozzle (100) comprising an inner channel (102) and an outer channel (104 encompassing the inner channel (102). The inner and outer channel (102, 104) are in hydraulic connection with the first and second inlet, respectively. The dual-channel nozzle (100) further comprises a joining path (106, 108) establishing a hydraulic connection between the inner channel (102), the outer channel (104), and a nozzle outlet (108) of the dual-channel nozzle (100). The joining path (106) is adapted for bringing the core polymer component (206) and the cladding polymer component (204) into contact with each other such that a contact layer comprising a mixture of the core polymer component (206) and the cladding polymer component (204) is formed between the core polymer component (206) and the cladding polymer component.

    摘要： A method for producing a polyurethane flooring (129) for a sports ground, wherein a polyurethane foam (128) is applied to a ground in at least two lanes arranged adjacent to each other, comprising the following steps: - providing polyurethane reactive components comprising a isocyanate component and a polyol component, - determining environmental data, - determining process parameters for mixing the components, the parameters depending on the environmental data, - mixing the foam (128) by mixing the isocyanate component and the polyol component using a froth foam process with the process parameters, - applying a first lane of the liquid foam (128) to a ground (103), - applying a second lane of the liquid foam (128) to the ground, wherein a side edge of the second lane gets in contact with a side edge of the first lane, wherein the process parameters are determined so that the foam (128) of the first lane is not cured before applying the foam (128) of the second lane.

    摘要： The invention relates to a method of manufacturing artificial turf (200), the method comprising:
    - creating (102) a polymer mixture (300, 400, 500) comprising
    • a first polymer (304; 404;504) in an amount of at least 57% by weight of the polymer mixture, wherein a portion (304, 404, 506) of at least 30 % by weight of the first polymer is made from the renewable carbon source; and
    • a second polymer (302; 402, 502) in an amount of at least 8 % by weight of the polymer mixture, the second polymer being HDPE;
    - extruding (104) the polymer mixture;
    - generating (106) the artificial turf fibers (202) from the extruded polymer mixture.
