(57) [Abstract] [Purpose] Adhesiveness to fibers, prevention of fluff and yarn breakage, general performance of fiber sizing agents such as weaving properties, and no decrease in tying force, and adhesion between fibers To provide a hot melt sizing agent with improved workability and low melt viscosity and excellent workability. [Structure] Polyvinyl acetate having a hydrophilic group, which contains a polyvinyl acetate-based resin (A) having a hydrophilic group, a hydroxy fatty acid having 6 or more carbon atoms or its derivative (B) and a plasticizer (C). 5 to 30 parts by weight of a hydroxy fatty acid having 6 or more carbon atoms or its derivative (B) and 1 to 20 parts by weight of a plasticizer (C) are blended with 100 parts by weight of the resin (A). |
