This invention provides a treatment liquid with excellent removal and stability of organic residues. It also provides a method for treating a substance related to the above treatment liquid. The treatment liquid contains water, hydroxylamine, and one or more hydrazines selected from hydrazine, hydrazine salts, and hydrazine derivatives, wherein the total content of the hydrazines is less than 1 part by mass relative to 100 parts by mass of hydroxylamine.

Provided is a fiber bundling agent that comprises an aqueous urethane resin composition containing a urethane resin and an aqueous medium, and that is characterized in that: the urethane resin is obtained by using, as essential raw materials, a polyol compound, a diisocyanate compound, a nonionic group-containing compound, and a hydrazine derivative having an active hydrogen atom; the polyol compound includes a polyester polyol; the diisocyanate compound includes an aliphatic diisocyanate compound and / or an alicyclic diisocyanate compound; the nonionic group-containing compound includes polyoxyethylene monomethyl ether and / or polyethylene glycol; and the percentage content of the nonionic group-containing compound is in the range of 3-10 mass% of the raw materials of the urethane resin. The fiber bundling agent exhibits excellent storage stability and bundling properties, generates less pyrolysis gases during molding, and can contribute to yellowing resistance of a formed product.
