Abstract
An industrial fabric of the variety used in the papermaking and similar industries has machine-direction (MD) yarns and cross-machine-direction (CD) yarns, which may be interwoven with one another to form a woven structure. The industrial fabric includes, as at least some of the MD and/or CD yarns, sheath/core yarns which have a core yarn surrounded by a sheath. The core yarn and the sheath are visually distinguishable by the naked eye from one another, such as by color, so that wear on a surface of the industrial fabric can be monitored visually during its operating life by the visual change that would become apparent when the sheath is worn away from the core yarn.
