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 means, with a suitable heated hydrophilic lubricant in a processing operation followed by heating to dry or "bake" the lubricant onto and/or into the surface of the fibers.
