Abstract
A nonionic hydrophilic macromolecule without added lubricating oil provides lubrication to textured at least partially oriented yarns to protect the yarns during subsequent processing, such as weaving to improve weaving efficiency. Softer yarns and fabrics are obtained than with conventional textured yarns while also providing improved adhesion and dyeability.
