The invention provides luminous optical fiber fabric capable of showing dynamic pictures. The fabric comprises a stripe synthesized pattern formed by optical fibers, the optical fibers constituting the pattern are optical fibers capable of performing side glowing or performing end surface glowing by damaging a surface protection layer through laser ablation, acetone corrosion or mechanical grinding, and can realize multi-point side surface glowing; luminous or non-luminous showingof the optical fibers in the pattern area is realized by controlling whether light rays are emitted into the optical fiber end surfaces; the stripe synthesized pattern can be divided into two or more stripe dividing patterns; the pictures are shown at certain time intervals, so that the dynamic pictures are formed. Meanwhile, the invention provides a preparation method of the dynamic luminous fabric. The fabric is ingenious in structure, attractive and practical and can show the dynamic pattern, the preparation method is scientific and easy to operate, and the problem that conventional fabric with the dynamic pictures is difficult to prepare due to the fact that design is complicated andaccurate dimensional coordination of a double-layer structure is neededissolved.
