<p>Disclosed is a spinning machine traveler in which even when spinning operation is performed at an ultra high spindle rotational speed of 25,000 rpm or more, it is possible to do away with running-in operation at the start of use of the traveler and to elongate the service life thereof. The traveler is formed by a base material consisting of hard steel wire, a nitrogen compound layer, and a sulfide layer such that the nitrogen layer is on the base material side. The nitrogen compound layer and the sulfide layer are formed by executing sulphonitriding treatment on the hard steel wire bent into a traveler shape. The borders between the base material, the nitrogen compound layer, and the sulfide layer are not necessarily clear. Nitrogen is diffused into at least the portion of the base material near the outer side thereof, and into the core depending upon the thickness of the traveler, to form a nitrogen diffusion layer. In the vicinity of the border between the nitrogen compound layer and the sulfide layer, a sulfide component is diffused in the nitrogen compound layer. <IMAGE></p> |
