<P>PROBLEM TO BE SOLVED: To provide a method for producing a fiber sizing agent that has excellent scouring properties in a post-processing step after weaving, is capable of providing adhesive properties such that a warp yarn breakage is suppressed and is capable of suppressing occurrence of removal of sizing agent; a sized yarn obtained by sizing with the fiber sizing agent obtained by the method; and a method for producing a woven fabric performed by using the fiber sizing agent. <P>SOLUTION: A method for producing a fiber sizing agent comprises a neutralized product of a copolymer. The method includes: a copolymerization process for copolymerizing polymerizable components containing (meth)acrylic acid, (meth)acrylic acid ester-based monomer and styrene-based monomer by an emulsion polymerization; and a neutralization process for neutralizing the copolymer obtained by the copolymerization process. <P>COPYRIGHT: (C)2013,JPO&INPIT |
