LOW-SLING FIBER LUBRICANT COMPRISING SHEARREDUCED HIGH MOLECULAR WIGHT POLYISOBUTYLENE

摘要

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.
