A straight-type finish, which has improved storage characteristics and is capable of preventing synthetic fibers from becoming electrically charged and uneven dyeing from being generated, contains a lubricant and a functional improvement agent at specified ratios. A metal organic sulfonate of a specified type is contained at least as a part of the functional improvement agent at a specified mass % of the total.
