Clear, stable low viscosity yarn lubricating compositions consisting of 40-60 percent by weight of a low viscosity hydrophobic lubricant such as butyl stearate and hexadecyl stearate; 20-55 percent by weight of a hydrophilic lubricant such as polyoxyethylene(2-10)fatty alcohols, polyoxyethylene(5-20)nonyl phenols, and polyoxyethylene(5-20)tridecyl alcohol; 5-15 percent by weight of selected antistats such as polyoxyethylene(8)lauric acid, polyoxyethylene(20)tallow amine, and polyoxyethylene(23)coconut fatty acid esters of glycerine, and from 0.1-5 percent of a polar coupling agent such as water, low molecular weight alcohols and low molecular weight alcohol-ethers are especially suitable for direct application in the processing of polyester and polyamide yarns.
A clear, stable yarn lubricating composition having a viscosity in the range of 35-65 centipoises as determined on a Brookfield Viscometer Model LVT using Spindle -1 at 60 R.P.M. at 75.degree. F. which consists essentially of:
A colorless, clear liquid blend consisting essentially of 55.0 parts isocetyl stearate;
