The invention provides a fabric with good unidirectional moisture conductivity and a preparation method thereof. The preparation method comprises the following steps that firstly, a fabric base material is pretreated by a calcium salt solution; then fibers are formed by using a polyvinyl alcohol/sodium alginate solution through an electrostatic spinning method and deposited on a single surface ofthe fabric; a polyvinyl alcohol/calcium alginate gel layer is formed on the surface of the fabric in situ by using polyvinyl alcohol/sodium alginate; and the spinning layer is further cross-linked byusing a crosslinking agent, a cross-linked polyvinyl alcohol/calcium alginate (PVA/SA) functional layer is formed, and the unidirectional moisture-conducting fabric is obtained. By means of the treatment mode, the unidirectional moisture-conducting fabric can be obtained, and the obtained fabric has good air permeability and antistatic performance. The unidirectional moisture-conducting fabric canbe used for manufacturing
