Vorrichtung zum Spinnen von Mantel-Kern-Verbundfaeden

摘要

A spinning device for producing sheath-core composite fibers. The device has an end plate with two kinds of openings, one to form the sheath component and the other to form the core component, the two kinds of openings supplying the streams of two different spinning solutions isolated from each other. The device has a first distributing plate which supplies the first spinning solution to the back side of a spinnerette plate and has openings therethrough to lead streams of the second spinning solution to second and third distributing plates. The second distributing plate has openings therethrough to lead the streams of the two different spinning solutions to the subsequent third distributing plate. The third distributing plate has flowing-down grooves on the surface contacting the second distributing plate to flow streams of the second spinning solution to the back side of the spinnerette. Sheath-component flowing-in grooves are provided in the device to supply sheath-component spinning solution from the first distribution plate so as to surround the core-component-forming spinning solution streams. The spinnerette plate has spinnerette orifices with axial centers substantially coinciding with the axial centers of the flowing-down grooves in the third distributing plate through which the composite fibers are extruded.
