PURPOSE:To improve discoloration resistance to chlorine of a final product of interknitted fabric from a polyurethane based elastic fiber and a polyamide based fiber and/or ordinary pressure-dyeable polyester based fiber, especially of a dyed product. CONSTITUTION:A substance being >=50mm equivalent/g in the reaction amount with chlorine measured according to a method described in this patent is added to interknitted fabric from a polyurethane based elastic fiber and a polyamide based fiber and/or ordinary pressure cation dyeable polyester based fiber and the interknitted fabric is further treated with resins to provide the objective dyed interknitted fabric having excellent discoloration resistance to chlorine, causing no lowering of discoloration resistance to chlorine by steam heating treatment such as washing or use in chlorine water, etc., and excellent in durability. |
