Application Of Pvd Coatings To Enhance The Wear Life Of Needles Used In The Textile Industry, Neil Donnelly

Masters

Needles are used in the textile industry for weaving. In high volume textile production a problem is wear of the needle eyelet as the threat is pulled through. This wear results in a cost to the textile manufacturer both in needle replacement, but in many cases more importantly, lost production during needle substitution The objective of this study was to examine the potential of wear resistant coatings deposited using the magnetron sputtering technique to increase the life-time of textile needles. Four coatings were evaluated, titanium nitride, titanium carbonitride, titanium diamond-like carbon and a novel coating titanium nitride/molybdenum disulphide. These coatings …
