Erucoyl Glycolates as Lubricants for Cotton Yarns

Abstract

Long-chain fatty acid derivatives of glycolic acid were evaluated as yarn lubricants for the preparation of cotton knitted fabrics. All experimental compounds imparted excellent lubricity, as measured by coefficient of friction, to both bleached and dyed cotton yarns. Yarns treated with polymeric sizing agents then topped with these compounds also exhibited improved lubricity. These treatments, therefore, have potential for greater efficiency in weaving as well as knitting fabrics. Frictional prop erties of these glycolic acid derivatives were among the best compared to commer cially available yarn lubricants.
