Abstract
Abstract A cloth having a semiconductor material deposited thereon is capable of producing a contact-potential difference when contacted with the skin for removing stiffness and recovering muscles from fatigue. The cloth is produced by pulverizing a contact-potential difference-generating substance such as germanium or silicon into a particle size of smaller than 200-250 μ, adding 4-100 g of the pulverized substance to 1 kg of a non-conducting organic polymer resin liquid or printing color paste, and printing or coating the mixture onto a woven or knit fabric.
