Cloth, in which air permeability is variable by energization, includes: a fibrous object composed of composite fibers, each of the composite fibers including: an electrical-conductive polymeric material; and a material different from the electrical-conductive polymeric material, the different material being directly stacked on the electrical-conductive polymeric material; and electrodes which are attached to the fibrous object, and energize the electrical-conductive polymeric material. Each of the composite fibers has a structure in which the material different from the electrical-conductive polymeric material is stacked on at least a part of a surface of the electrical-conductive polymeric material, or a structure in which either one of the electrical-conductive polymeric material and the material different from the electrical-conductive polymeric material penetrates the other material in a longitudinal direction. The cloth is capable of controlling the air permeability by a control factor enabling weight reduction and space saving. |
