An optical energy dual-layered composite fabric is formed by interweaving an inner woven layer and an outer woven layer. The inner woven layer is formed by weaving hydrophobic polypropylene fibers, while the outer woven layer is formed by weaving hydrophilic polyester fibers so that through such a definition of physical properties, control can be achieved for the outer woven layer and the inner woven layer to be both colored by fluorescent dyes when being dyed, and also, further control can be achieved to have the ratio of the fluorescent dye of the outer woven layer greater than that of the fluorescent dyes of the inner woven layer such that the outer woven layer that has a darker color can be of better color fixation and may effectively convert sun light into visible light of a specific wavelength while the inner woven layer that has a lighter color may reflect, as a mirror surface, ultraviolet light back and may also provide a synergistic effect of guiding light as having the same molecules of fluorescent dyes of the outer woven layer to thereby greatly optimize the transmission ratio of the visible light to provide an enhanced minor amount phototherapeutic beautification effect for skin.一種由一內織層及一外織層交織而成之光能兩層複合織物。該內織層係以具疏水物性之聚丙烯纖維織成,而外織層係以親水性之聚酯纖維織成,藉由該物理性界定,俾控制該外織層及內織層於染色時除能全部上色有螢光染料外,且能進一步控制外織層之螢光染料比例係大於內織層之螢光染料,以使較深色外織層除具有較佳之色牢度外,且能有效將太陽光轉換成特定波長可見光,至於較淺色之內織層仍能鏡面反射紫外線,且對外織層螢光染料具有同分子引導可見光之加乘作用,據以大大優化該等可見光之穿透率,以便對皮膚發揮更為優異之微量光療美容作用。10‧‧‧內織層11‧‧‧纖維20‧‧‧外織層21‧‧‧纖維22‧‧‧槽道30‧‧‧螢光染料40‧‧‧二氧化鈦
