Abstract:
1. A process for forming textile yarns into fabric, the process comprising the steps of applying to said textile yarns a wax-free and oil-free aqueous emulsion size mixture comprising a polyvinyl alcohol and a hydrophilic lubricant macromolecule to deposit a lubricating-effective amount of the hydrophilic lubricant macromolecule and the polyvinyl alcohol onto said textile yarns and form sized textile yarns, wherein the textile yarns are a blend of cotton and synthetic fiber, and wherein the hydrophilic lubricant macromolecule is a condensation product of aromatic ester groups which contains from about 10 to 50% by weight of ethylene terephthalate repeat units together with from about 50 to 90% by weight of oxyethylene repeat units, removing the water from the sized textile yarns, and forming fabric from said sized textile yarns, wherein the molar ratio of ethylene terephthalate repeat units to oxyethylene repeat units is from about 1:20 to about 1:2.
