AQUEOUS COMPOSITION, METHOD FOR STABILIZING AQUEOUS BLOCKED POLYISOCYANATE, FIBER TREATMENT AGENT COMPOSITION, AND FIBER

摘要

The purpose of the present invention is to provide: an aqueous composition which has excellent storage stability and is capable of providing good durability in terms of washing even after storage; a method for stabilizing an aqueous blocked polyisocyanate; a fiber treatment agent composition which contains the aqueous composition; and a fiber which is treated with the fiber treatment agent composition. An aqueous composition which contains: an aqueous blocked polyisocyanate that has an isocyanate group to which a hydrophilic group is added and a blocked isocyanate group wherein an isocyanate group is blocked with a blocking agent; an amine compound in an amount of 10-400% by mole relative to the blocked isocyanate group; and water.
