摘要： The invention provides for a method of manufacturing artificial turf (1000). The method includes creating a polymer mixture, such as polymer mixture (400), where the polymer mixture is at least a three-phase system. The polymer mixture includes a first polymer, a second polymer and a compatibilizer. The first polymer is a polyamide (PA) and the second polymer is a polyethylene (PE). The first polymer is included in an amount of 0.125 percent to 5 percent by weight, the second polymer is included in an amount of 60 percent to 97 percent by weight and the compatibilizer is included in an amount of 0.375 percent to 15 percent by weight. The first polymer and the second polymer are immiscible, and the first polymer forms polymer beads surrounded by the compatibilizer within the second polymer.

摘要： A method for producing polyurethane flooring includes providing polyurethane reactive components including a isocyanate component and a polyol component, determining environmental data, determining process parameters for mixing the polyurethane reactive components, wherein the process parameters depend on the environmental data, mixing the foam for the polyurethane flooring 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 to a ground, applying a second lane of the liquid foam 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 parameter are determined so that the foam of the first lane is not cured before applying the foam of the second lane. Furthermore, the invention relates to an apparatus and a system for producing a polyurethane flooring.

摘要： A method of manufacturing artificial turf includes the steps of: creating a polymer mixture including at least one polymer and a nucleating agent for crystallizing the at least one polymer, extruding the polymer mixture into a monofilament; quenching the monofilament; reheating the monofilament; stretching the reheated monofilament to form the monofilament into an artificial turf fiber, wherein during the stretching the nucleating agent boosts the creation of crystalline portions of the polymer within the monofilament; incorporating 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.

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

摘要： 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.
