• characterized in that the layer thickness (d) of the wear-resistant coating (17) is at least 2 μm.

The textile machine tool part according to any of the preceding claims,

• characterized in that the wear-resistant coating (17) is a chromium coating or a DLC coating or a carbidic coating or a nitridic coating.

The textile machine tool part according to any of the preceding claims,

• characterized in that the core material is formed from a metal material or a metal alloy.

The textile machine tool part according to any of the preceding claims,

• characterized in that the microstructure (19) of the core surface (18) and/or the microstructure (22) of the wear-resistant coating (17) has elevations (21, 24) and depressions(20, 23), wherein the elevations (21, 24) in the region of their maximum, and/or the depressions (20, 23) in the region of their minimum, have an approximately spherical surface segment-shaped contour.

A use of the textile machine tool part (10) according to any of the preceding claims in a textile machine during a method for producing or processing a textile material with at least one elastane yarn that comes into contact with the textile machine tool part (10).

A method for producing a textile machine tool part having the following steps:

• Production of a tool core (16) from a core material,
• Creation of a microstructure (19) in at least one section of the core surface (28) of the tool core (16),
• Coating of at least part of the core surface (18) having the microstructure (19) with a wear-resistant coating (17) that has a layer thickness (d) of at most 20 μm such that the wear-resistant coating (17), due to the microstructure (19) of the core surface (18), also has a microstructure (22).
