Abstract:
A treating agent for imparting a durable press configuration on a fiber product selected from the group consisting of chemical fibers and wools by a heating treatment, which comprises 0.01 to 20 percent by mass of a vinyl polymer containing a monomer unit selected from the following monomer units (A), (B) and (C) (provided that if the monomer unit (C) is not selected, both of the monomer units (A) and (B) are selected), wherein the ratio of a sum of the monomer units (A), (B) and (C) is 50 to 100 mol-% of the total constituent monomer units, and the content of a nonvolatile matter is 0.01 to 30%:the monomer unit (A): a vinyl monomer unit having a carboxy group, which is maleic acid, the monomer unit (B): a vinyl monomer unit having a hydroxyl group, selected from the group consisting of oxyethylene adduct and oxypropylene adduct, and the monomer unit (C): a vinyl monomer unit having a carboxy group and a hydroxyl group; wherein the vinyl polymer is a polymer capable of forming a self-crosslinked structure by heating, the treating agent possesses a pH at 20Â° C. of 3.0 to 6.5, and the equivalent ratio of the carboxy group to the hydroxy group is from 7:3 to 2:8, provided that when the vinyl polymer contains the monomer unit (A), said monomer unit (A) is present in a range of less than 50 mol-% in the polymer.
