    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: The method includes creating a polymer mixture, wherein the polymer mixture includes a stabilizing polymer, a bulk polymer, a flame retardant polymer combination, and a compatibilizer. The stabilizing polymer polymer and the bulk polymer are immiscible. The stabilizing polymer includes fibers surrounded by the compatibilizer within the bulk polymer. The stabilizing polymer is aramid. The flame retardant polymer combination is a mixture of triazin and melamine. The method further includes extruding the polymer mixture into a monofilament. The method further includes quenching the monofilament. The method further includes reheating the monofilament. The method further includes stretching the reheated monofilament to align the fibers relative to each other and to form the monofilament into an artificial turf fiber. The method further includes incorporating the artificial turf fiber into an artificial turf backing.
