Abstract

The present invention provides an elastic fiber dry spinning component and spinning part. The spinning component includes: a temperature control box (3) including a box body (31), wherein the box body (31) is longitudinally provided with multiple polymer solution channels (32) separated from each other; areas in the box body (31) other than the polymer solution channels (32) are cavities, and the cavities are used for circulation of a fluid medium that exchanges heat with an elastic fiber dry spinning polymer solution in the polymer solution channels (32); and a spinneret part (4) detachably connected to the temperature control box (3), wherein the spinneret part (4) includes multiple spinneret orifice sets (41) separated from each other, and the multiple spinneret orifice sets (41) are correspondingly in communication with outlets of the multiple polymer solution channels (32). The spinning part includes a metering device and the above-mentioned spinning component; the metering device is detachably connected to the temperature control box (3) and is used for metering and allocating the elastic fiber dry spinning polymer solution to the multiple polymer solution channels (32). The spinning component and the spinning part are convenient to install and maintain and are highly efficient.
