The present invention relates to a copolyester conjugated fiber capable of using hot water at a low temperature and a method for producing the same. More particularly, the present invention relates to a fiber having excellent properties such as a change in physical properties of a fiber forming component And at the same time, the elution is uniform, thereby preventing defective dyeing non-uniformity of the final fiber after the weight reduction step. Moreover, it is possible to prevent alkaline infiltration of the fiber forming component due to excellent application to water other than alkali, It can contribute to the reduction of safety and alkali cost, the cost of alkali wastewater treatment, and the eco-friendly reduction process. Further, the present invention relates to a copolyester conjugated fiber having low biodegradability and capable of self-decomposition at the time of landfill disposal, thereby minimizing environmental pollution, and a method for producing the same. |
