REGENERATED CELLULOSE FIBER WITH PHOTOTHERMAL CONVERSION PROPERTY, METHOD FOR PRODUCING THE SAME AND FIBER STRUCTURE

摘要

PROBLEM TO BE SOLVED: To provide a regenerated cellulose fiber with photothermal conversion properties, which has photothermal conversion particles dispersed in the fiber in a fine particle state, has a high photothermal conversion function, has adequate antistatic properties, and has almost the same properties such as a color tone and texture as a usual rayon fiber; a method for producing the same; and a fiber structure.SOLUTION: The regenerated cellulose fiber contains the photothermal conversion particles having heat ray absorbing properties in the fiber. The photothermal conversion particle is a particle having a BET specific surface area of in a range of 5-120 m/g and a powder resistance of less than 30 &OHgr; cm, and is contained in the fiber in a dispersed state. The method for producing the regenerated cellulose fiber comprises: preparing an aqueous dispersion liquid of the photothermal conversion particles; mixing the aqueous dispersion liquid with a viscose stock solution containing cellulose to prepare a viscose solution for spinning; extruding the viscose solution for spinning from a nozzle to form a fiber; and coagulating and regenerating the fiber.
