Abstract
A twister ring lubricant is formulated using a major portion of paraffin wax and a minor portion of conventional oil or grease. In the manufacture of ply which is used in making cord, the individual filaments are fed through the eye of a nylon traveler which spins around a steel twister ring. Two or more plies are cabled to form a cord also using a traveler which spins around a twister ring. The twister ring lubricant reduces the sliding friction between the nylon traveler and the steel twister ring.
Claims3
In a method for twisting yarn by passing the yarn through the eye of a nylon traveler turning on a twister ring to twist the yarn and feed it onto a rotating bobbin, wherein the surface of the twister ring is lubricated with a lubricant comprising a mixture of a lubricating oil and a paraffin wax, the improvement comprising lubricating the surface of the twister ring in contact with the traveler with a solid lubricant consisting essentially of a minor amount of the lubricating oil having an SUS viscosity at 20.degree. C. in the range of 30-600 selected from the group consisting of hydrorefined naphthenic petroleum oil, hydrorefined paraffinic petroleum oil, solvent refined paraffinic petroleum oil, hydrogenated polyolefin oil, and mixtures thereof and a major amount of the paraffin wax whereby the friction between the traveler and the twister ring is reduced.
In a method of lubricating a yarn twister ring wherein the improvement comprises applying to the ring a solid lubricant consisting essentially of a minor amount of lubricating oil having an SUS viscosity at 20.degree. in the range of 30-600 selected from the group consisting of hydrorefined naphthenic petroleum oil, hydrorefined paraffinic petroleum oil, solvent refined paraffinic petroleum oil, hydrogenated polyolefin oil, and mixtures thereof and a major amount of paraffin wax whereby the friction between a traveler riding on the ring and the ring is reduced.
