    • 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 Ω 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.
    • 要解决的问题:为了提供具有光热转化性能的再生纤维素纤维,其具有分散在细颗粒状态的纤维中的光热转化颗粒,具有高的光热转化功能,具有足够的抗静电性能,并且具有几乎相同的性质 作为通常人造纤维的色调和质感; 其制造方法; 和纤维结构。解决方案:再生纤维素纤维含有在纤维中具有热射线吸收特性的光热转化颗粒。 光热转化颗粒是BET比表面积在5-120m 2 / g,粉末电阻小于30%的颗粒; cm,并以分散状态包含在纤维中。 再生纤维素纤维的制造方法包括:制备光热转化颗粒的水性分散液; 将水分散液与含纤维素的粘胶储备溶液混合,制备用于纺丝的粘胶溶液; 从喷嘴挤出用于纺丝的粘胶溶液以形成纤维; 并使纤维凝结和再生。
