Development of optical fiber fabric with pattern color changeable

To obtain a novel luminescent fabric,optical fibers and common yarns are used to fabricate a union fabric which has patterns on its surface that are formed by optical fibers via double picks structure design,and by utilizing the lateral light emitted from the crooked optical fibers in the fabric,coupled with circuit design and control unit design,the Chinese character ″FU″ woven with optical fibers in this fabric deplays in green light and red light alternatively.This light-emitting fabric with changeable patterns and colors has light-emitting diodes as its light source,and BM-5A luminance colorimeter is used to measure its luminance,the value is ranging from 0.7 to 4.5 cd /m2,far higher than that can be observed by human eye.The luminescent fabric developed in this paper can be used for all kinds of decoration and further development as flexible displays.
