Abstract
A conductive far-infrared heat-generating fiber and a preparation method therefor. In the process of preparing the conductive far-infrared heat-generating fiber, the preparation method specifically comprises: A) pretreating a matrix fiber, and then drying same; B) impregnating, in a coating liquid of a conductive material, the matrix fiber obtained in step A, and then drying same; and performing step B) at least once, and obtaining the conductive far-infrared heat-generating fiber. The preparation method for the conductive far-infrared heat-generating fiber is simple and can realize good control of resistivity and heat generation.
