Lubricant for textile machinery
Abstract
Abstract A lubricating composition that is uniquely designed for the lubrication of textile machinery such as a circular knitting machine comprises a lubricating oil containing zinc oxide as an antiwear agent. The zinc oxide is incorporated in the lubricating oil composition by first preparing an additive concentrate wherein up to 10 weight percent of zinc oxide has been dispersed in a lubricating oil using as a dispersing agent zinc naphthenate, magnesium naphthenate or mixtures thereof. The lubricating composition also preferably contains an oiliness agent, an antioxidant and an extreme pressure agent. The zinc naphthenate or magnesium naphthenate not only serves to suspend the zinc oxide but also imparts scourability to the composition, thereby aiding in the removal of the lubricant from the textile processed by the textile machinery.
