Abstract
Abstract A fabric formed from fiber-like strands of hollow, transparent filaments which have been woven or otherwise joined together is disclosed. The hollow strands contain a liquid in which color-coded micromagnets are dispersed. The micromagnets are free to rotate within the filament, the fabric thereby being capable of changing colors, either selectively or totally, when an activating magnetic force causes the micromagnets therein to rotate. The fabric may incorporate, in place of color-coded micromagnets, other orientable bodies which are also capable of being oriented, as for example by an electromagnetic or electrostatic force field, to produce a visual display. Further, the fabric may comprise a material having one or more liquid filled veins, the liquid again containing color-coded micromagnets or orientable bodies dispersed therein.
