(57) [Summary] [Structure] A warp sizing agent for spun yarns, which comprises starch, polyvinyl alcohol-based resin, and starch-based compound obtained by graft-polymerizing an olefin-based monomer having a carboxyl group onto starch. [Effect] The compatibility of the paste solution is good, and even when the paste solution is stored without stirring or under weak stirring, phase separation does not occur and stable pasting can be performed for a long time. As a result, a uniform sizing thread can be provided, and the sizing thread can be provided with good weaving properties, and the sizing workability is also improved. |
