The invention provides a production method of colored cotton blend light-sensitive heat energy fabric. The production method is characterized by comprising a fabric body, wherein the fabric body comprises a decoration layer, a light condensing layer, a conducting film, a temperature control layer and a protection layer from outside to inside. A plurality of hollow points distributed regularly are formed on the surface of the decoration layer, the light condensing layer is formed by connecting a plurality of ultrathin monomer nano-photocell panels in series, the conducting film is pasted on the inner side of the light condensing layer, the temperature control layer is a cavity organically sealed by a thickened plastic film, the temperature control layer is filled with a mixture of water and nano salt particles, the upper side of the temperature control layer is communicated with the conducting film by a transmission line, a self-control contact is arranged at any end of the temperature control layer, and the protection layer is laminated with the inner side of the temperature control layer in a hot melting manner. The production method provided by the invention has the positive effects: the fabric can keep warm and is comfortable after cotton is blended, heating and warm keeping are realized by a light source, and the fabric is practical and environment-friendly, so as to better meet dressing requirements of consumers in winter and in cold regions.
