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.

摘要： 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.
