Abstract

Ultrahigh molecular weight (average mw at least about 5,000,000) polyisobutylene additives are compounded with mineral oil vehicles under very low shear conditions to provide consistently low-sling fiber lubricants for a range of textile operations; the lubricants are particularly suited for very high speed operations.
