Disclosed are eccentric sheath-core colored fibers, a preparation method and a preparation device thereof, and belong to the technical field of chemical fibers. The colored fiber comprises a sheath layer and a core layer, the sheath layer is wrapped around the outer periphery of the core layer, wherein, as viewed from the cross section of the eccentric sheath-core colored fiber, the core layer is offset from the geometric center of the sheath layer; the colors between the core layer and the sheath layer are different. The method comprises the following steps: preparing a core layer melt containing a first colorant and a sheath layer melt containing a second colorant; selecting a spinneret plate comprising a first spinning orifice and a second spinning orifice; under the condition of a set temperature, making the core layer melt flow through the first spinning orifice while the sheath layer melt flows through the core layer melt, and forming a first intermediate product at the outlet of the first spinning orifice and the outlet of the second spinning orifice; after post-treatment, a filament or a short fiber of the eccentric sheath-core colored fiber is obtained. The device comprises the spinneret plate. The eccentric sheath-core colored fiber prepared by the preparation method and the preparation device can make the core layer be eccentrically distributed in the sheath layer.
