Economical diamond coating for durable and wear-resistant textile machinery elements

The processing of spun-dyed and industrial yarns in the textile industry leads to considerable abrasive wear on machine ele ments, depending on the yarn. For example, an abrasively worn thread guide can affect product quality in downstream process stages. The DiaTex research project is therefore developing an economical and cost-efficient CVD diamond-coated yarn guide that leads to a significant increase in service life. This is being achieved by developing a two-part thread guide consisting of a bearing base body and a highly wear-resistant contact zone that is coated with CVD diamond using a direct process. The technology is expected to reduce reject rates, minimize set-up times, increase productivity and improve yarn quality. It can be exten ded to other applications, which increases the competitiveness of the German textile industry.
