用されている。Conventionally, in a spinning machine traveler used in a spinning machine or a yarn twisting machine, the operating conditions are such that the yarn passes through the yarn passage section at high speed, or
Under operating conditions where the yarn contains special additives, wear resistance of the yarn passage section is required. Therefore, in order to improve this abrasion resistance, the surface of the yarn passing section is usually hardened.
Travelers with chrome plating or satin chrome plating are used.

問題点がある。However, due to faster operating conditions and specialization of the yarn being spun, in the conventional chrome-plated or matte chrome-plated travelers mentioned above, the yarn passing section wears out quickly, resulting in a decrease in yarn quality, yarn fuzz, and yarn breakage. There are problems in that it is not possible to obtain particles that are stable when the traveler is turned on, resulting in a short life and an increase in the number of steps required to replace the traveler.

A Cr-C alloy plating layer obtained from a bath using potassium formate as an agent has a film thickness of 5 μ to 30 μ, and a surface roughness of 1.5 μ to 3.5 μ (reference length 0 .8nwn), and further applied a hot air layer to increase the height of the Cr-C alloy plating layer from Hv1200 to Hv.
1600, the problem was solved by improving the abrasion resistance of the yarn passage section.
