  • the invention relates to a fiber-guiding textile machine plastic part for guiding fibers or a yarn produced therefrom.
  • the invention further relates to a textile machine with fiber-guiding functional components.
  • the invention further relates to a method for producing a fiber-guiding textile machine functional component for guiding fibers or a thread produced therefrom.
  • the invention also relates to a use of a plastic body with a chemically deposited functional surface layer.
  • the invention has for its object to be able to produce generic fiber-engineered textile machinery functional components cost-effective.
  • the object of the invention is achieved by a fiber-guiding textile machine plastic part for guiding fibers or a yarn produced therefrom with a wear-resistant functional surface layer of a chemically deposited layer, wherein the wear-resistant functional surface layer by means of cavities produced on the surface of the fiber-guiding textile machine plastic part with the fiber-guiding textile machines Plastic part is particularly intimately connected by positive locking.
  • inventive fiber-guided textile machine plastic parts can be produced much cheaper than conventional textile machine functional components for guiding fibers or a thread produced therefrom.
  • the present wear-resistant functional surface layer is not comparable to such an optically beautifying surface layer. Therefore, it is also evident to use such a chemically deposited layer as a wear-resistant functional surface layer on textile machine functional components for guiding fibers.
  • a textile machine functional component for guiding fibers or a thread produced therefrom by a fiber-guiding textile machine plastic part with a wear-resistant functional surface layer of a chemically deposited layer is characterized.
  • This fiber-guided textile machine plastic part is also extremely resistant, since the wear-resistant functional surface layer is particularly intimately connected by positive engagement with the plastic surface.
  • This particularly intimate connection is based on the fact that on the surface of the plastic part prior to the deposition of the chemical layer, a multiplicity of caverns have been produced, into which this chemically deposited layer can at least partially penetrate.
  • the advantageous positive connection is produced.
  • the object of the invention is also achieved by using a synthetic material body having caverns on its surface with a functional surface layer which is chemically deposited on the surface and in the caverns and is particularly intimately connected with the plastic body as a fiber-guiding textile machine functional component.
  • fiber-guided textile machine functional components can be produced advantageously, for example as a plastic injection-molded component.
  • the wear-resistant functional surface layer is a chemical nickel layer.
  • a chemical nickel layer is particularly advantageous in view of the fact that subsequent heat treatment, in particular annealing, of the fiber-guiding textile machine plastic part is not possible in order to increase the layer hardness.
  • chemico-nickel layer has heretofore been used merely as an intermediate carrier layer for other layers, such as an acid copper layer and / or a glossy nickel layer or the like, but not as a wear-resistant functional surface layer on a fiber-guiding textile machine plastic part textile machine.
  • a particularly preferred embodiment provides that the wear-resistant functional surface layer is a low-phosphorus-containing nickel phosphorus layer.
  • the present wear-resistant functional surface layer could also be produced by means of a medium phosphorus-containing nickel phosphorus layer.
  • a particularly hard and thus particularly resistant chemically deposited layer can be achieved on the fiber-guiding textile machine plastic part according to the invention.
  • the fiber-guiding textile machine plastic part is equipped with a low phosphorus-containing nickel phosphor coating.
  • the object of the invention is also achieved by a method for producing a fiber-guiding textile machine functional component for guiding fibers or a yarn produced therefrom, in which the fiber-guiding textile machine functional component is produced from a plastic body, and in which caverns on the plastic body in a pickling process be produced and the plastic body is then coated in a low phosphorus solution with a wear-resistant functional surface layer, wherein the wear-resistant functional surface layer is particularly intimately connected by a cavitation caused by the positive connection with the plastic body.
  • plastic bodies designed as fiber-conveying textile machines can be coated with a long-lasting phosphorus-containing nickel-phosphorus coating.
  • the fiber-guiding textile machine plastic parts according to the invention can easily be produced in larger quantities and at low cost.
  • plastic parts are previously pretreated accordingly. For example, they are cleaned of dirt and grease.
  • palladium may preferably be added to the thus prepared surface of the fiber-guiding textile machine plastic part prior to coating in order to favor the coating process of the wear-resistant functional surface layer.
  • a further preferred embodiment provides that the wear-resistant functional surface layer has a hardness of 700 HV or more.
  • Such Vickers hardnesses can be achieved consistently with a low-phosphorus nickel phosphorus layer in the chemical deposition process on the fiber-guiding textile machine plastic part consistently, which sufficiently stable and durable fiber-bearing textile machine plastic parts can be provided.
  • a long-lasting functional capability of the wear-resistant functional surface layer on the fiber-guiding textile machine plastic part can be ensured particularly reliably if the wear-resistant functional surface layer has a layer thickness of more than 8 ⁇ m or more than 10 ⁇ m. In addition, such a layer thickness promotes good corrosion resistance.
  • the wear-resistant functional surface layer has a layer thickness of less than 30 ⁇ m or less than 20 ⁇ m, the production costs with regard to the wear-resistant functional surface layer can be kept lower.

  • the fiber guide surface area can be channel-shaped or open-channel-shaped in the direction of its longitudinal extent.
  • the channel-shaped fiber guide surface area is round, oval, or rectangular in cross-section, in order to be able to guide fibers accordingly.
  • channel-shaped fiber guide surface area may be straight or curved in the direction of its longitudinal extent.
  • fiber guide surface regions directed towards one another on the fiber-guiding textile machine plastic part are designed with the wear-resistant functional surface layer, so that the fiber-guiding textile machine plastic part is sufficiently well protected against mechanical stress caused by fibers.
  • the fiber-guiding functional component is designed to be very wear-resistant on its insides by precisely this low-phosphorus-containing nickel phosphorus layer.
  • the fiber-guiding textile machine plastic part may also have further layers, which may be arranged in particular between the plastic body and the outer low-phosphorus nickel phosphorus layer.
