Abstract

An improved high retention lubricant for textile-machinery comprises a naphthenic base oil, a tackiness agent (e.g., polyisobutylene), and an effective amount of a lithium soap (e.g., 0.1 to 1.5% lithium stearate) to provide a MacMichael viscosity at 70.degree.F of at least 5, more preferred at least 15 (preferably 20 to 35). Typically, the base oil can have a viscosity in the range of 60 to 600 SUS at 100.degree.F (more preferably 125 to 300 SUS) and an aniline point in the range of 150 to 170.degree.F, said base oil comprising at least one hydrorefined naphthenic oil component having a viscosity in the range of 40 to 12,000 SUS at 100.degree.F, and preferably, is a wide boiling range blend containing at least two such hydrorefined naphthenic oils.

Dependent claims

A high retention lubricant for textile-machinery, said lubricant comprising a base oil, an effective amount of a tackiness agent for retention in a bearing, and sufficient lithium soap to provide a MacMichael viscosity at 70.degree.F in the range of 5 to 15, said base oil having a viscosity in the range of 60 to 600 SUS at 100.degree.F, a 335 UVA in the range of 0.01 to 0.4, and an aniline point in the range of 150.degree. to 170.degree.F, and containing in the range of 85 to 100% of at least one hydrorefined naphthenic oil component having a viscosity in the range of 40 to 12,000 SUS at 100.degree.F, said tackiness agent being selected from the group consisting of polyacrylates, aluminum oleate, olefin polymer, hydrogenated olefin polymer, mixtures of hydrogenated and unhydrogenated olefin polymer, and natural rubber obtained from dehydrated latex.
