Title:

SPANDEX FIBER DRY SPINNING COMPONENT AND SPINNING PART

Document Type and Number:

WIPO Patent Application WO/2016/086383

Kind Code:

A1

Abstract:

A spandex fiber dry spinning component and spinning part. The spinning component comprises: a temperature controlled box (3), which comprises: a housing (31), where the housing (31) is longitudinally provided with multiple polymer solution channels (32) separated from each other, areas in the housing (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 a spandex fiber dry spinning polymer solution in the polymer solution channels (32); and, a spinneret (4) detachably connected to the temperature controlled box (3), where the spinneret (4) comprises multiple filament-spraying nozzle sets (41) separated from each other, and the multiple filament-spraying nozzle sets (41) are correspondingly in communication with outlets of the multiple polymer solution channels (32). The spinning part comprises a metering apparatus and the spinning component. The metering apparatus is detachably connected to the temperature controlled box (3) and is used for metering and allocating the spandex fiber dry spinning polymer solution to the multiple polymer solution channels (32). The spinning component and the spinning part are convenient to install and service and are highly efficient.
