Claim 3:
4. A fiber optic fabric comprising:
a pattern formation part forming a fiber optic pattern on the surface, and
a main body part having a surface free of optical fibers,
wherein the pattern formation part being comprised of:
a leno-weave fabric made by interweaving first warp yarns which are transparent warp yarns and transmit at least part of light and second warp yarns which are opaque warp yarns with first weft yarns which are fiber optic weft yarns, with the first warp yarns and the second warp yarns being twisted in opposite direction around the first weft yarns,
the first weft yarns forming a fiber optic pattern on the surface, and
the first weft yarns always going under the first warp yarns and always going over the second warp yarns during weaving; and
the main body part being comprised of:
a leno-weave fabric made by interweaving first and second main body part warp yarns with first main body part weft yarns, with the first and second main body part warp yarns being twisted in opposite direction around the first main body part weft yarns,
wherein the fiber optic fabric being formed by the pattern formation part and the main body part in which the first warp yarns and the second warp yarns of the pattern formation part are continued across the main body part, forming first main body warp yarns and second main body part warp yarns, and
wherein the pattern forming part further comprises: second weft yarns which are alternately arranged with the first weft yarns next to each other as seen on the same plane of the pattern formation part, and
during weaving, the first and second weft yarns run together through the same slots or run separately through different slots that are formed by the first and second warp yarns,
with the second weft yarns always going under the first warp yarns and always going over the second warp yarns, and
the second weft yarns are pattern formation weft yarns of a certain color for creating a pattern when the first weft yarns are not illuminated.
