METHOD FOR DYEING POLYESTER-BASED WOVEN AND/OR KNIT GOODS OR NONWOVEN FABRIC

摘要

PROBLEM TO BE SOLVED: To improve the dyeability of polyester-based woven and/or knit goods or nonwoven fabric, to achieve deep-coloring dyeing by a dye, and to improve the resistance to washing of dyed woven and/or knit goods or nonwoven fabric. SOLUTION: A method for dyeing polyester-based woven and/or knit goods or nonwoven fabric comprises the following processes: a process that the polyester-based woven and/or knit goods or nonwoven fabric is irradiated with the plasma or ionizing radiation to form active species; a process that the active species are subjected to graft copolymerization with a polymerizable monomer; and a process that the polyester-based woven and/or knit goods or nonwoven fabric is dyed with a dye.
