Abstract
A synthetic fiber treatment agent and synthetic fibers including the synthetic fiber treatment agent, wherein the synthetic fiber treatment agent contains a silicone and a polyoxyalkylene alkyl ether in which an alkylene oxide with 2 to 4 carbon atoms is added at a ratio of 1 to 30 moles in total to 1 mole of a monohydric aliphatic alcohol having a hydroxy group at a β-position of an alkyl chain with 4 or more carbon atoms.
Claims7
