BLOCKED POLYISOCYANATE WATER DISPERSION, FIBER PROCESSING AGENT COMPOSITION, AND FABRIC

摘要

The purpose of the present invention is to provide: a blocked polyisocyanate water dispersion having favorable water dispersion stability, capable of achieving high coating strength, exhibiting excellent mechanical stability as a fluorine-doped fiber processing agent, and capable of producing a fabric having high washability; and a fiber processing agent composition containing the same. The blocked polyisocyanate water dispersion contains water and a blocked polyisocyanate at least having component units (1-3), and has an average dispersed particle diameter of the blocked polyisocyanate of phi=1-250nm. 1) A polyisocyanate unit having at least one type of diisocyanate monomer unit selected from a group consisting of aliphatic diisocyanate monomers and alicyclic diisocyanate monomers. 2) A polyethylene oxide unit having a hydroxyl group on one end. 3) A blocking agent unit.
