Abstract
Fibers such as caustic treated non round polyester fibers are prepared having certain lubricants strongly adhered to the surfaces thereof. These fibers are prepared by contacting the fibers, such as immediately prior to a crimping device, with a suitable heated hydrophilic lubricant in a processing operation followed by heating to dry or the lubricant onto and/or into the surface of the fibers.
