[PROBLEMS] To provide a knitted fabric having excellent stretchability, dimensional stability, fit to skin, excellent strength retention, and rich in design. A dyeing method for a knitted fabric knitted only with a knitting yarn made of polyurethane-based elastic fibers. The polyurethane-based elastic fiber is a polyurethane-based elastic fiber obtained mainly by the reaction of a polymer diol, diisocyanate, and a chain extender, and contains a polymer containing a sulfonic acid group. The polyurethane elastic fiber is dyed at 30 ° C. or higher and 130 ° C. or lower with a cationic dye at least either before or after knitting of the knitted fabric. [Selection figure] None |
