摘要

PURPOSE: A method for attaching a functional processing agent to fiber while enhancing color fastness is provided to enhance color permeability. CONSTITUTION: A method for attaching a functional substance to a dyed material with enhanced color fastness comprises: a step of opening fibers using protease, amylase, and cellulase to bulk the fibers; a step of fixing dye and functional processing agent to the fibers; and a step of polymerizing the functional processing agent.
