Methods For Producing and Using a Textile Machine Tool Part

A method of using a textile machine tool part (10, the textile machine tool part (11) comprising:

• a working section (12) configured to contact a thread or yarn;
• a holding section (14) configured to be held or moved by a textile machine;
• a tool core (16) that comprises a core material;
• wherein the tool core (16) in the working section (12) has a core surface (18) having a microstructure (19), at least in one section of the core surface;
• wherein the microstructure (19) of the core surface (18) has depressions and elevations that are connected to one another, wherein the depressions are depressed in a concave manner relative to a reference plane, while the elevations are raised in a convex manner relative to the reference plane, wherein a diameter of individual ones of the depressions and/or elevations is at most 60 μm and wherein a distance between a maximum depth of individual ones of the depressions and a maximum height of individual ones of immediately adjacent elevations is at least 10 μm and at most 60 μm;
• wherein the core surface (18) having the microstructure (19) is coated, at least in part, with a wear-resistant coating (17) that has a layer thickness (d) of a maximum of 20 μm and wherein an outer surface of the wear-resistant coating (17) also has a microstructure (22) due to the microstructure (19) of the core surface (18);
• and
• wherein the outer surface of the wear-resistant coating (17) forms at least part of an outer surface of the textile machine tool part (11);
• wherein the method comprises:
• producing or processing a textile material in a textile machine with at least one elastane yarn that comes into contact with the textile machine tool part (10).
