ABSTRACT OF THE DISCLOSURE An apparatus and a process are disclosed for preparing a new type of conjugate fiber composed of multiple layers of different polymer materials. In the process, different fluid polymers are continuously supplied through parallel passages in a movable peripherally grooved flat plate to a chamber situated between said flat plate and a spinneret plate. As the polymers are supplied to the chamber, the flat plate is moved relative to the spinneret plate so that a multiple layer polymer flow results wherein the different poly- fiber is obtained in which the different polymers are alternately arranged along the fiber. The interfaces between the different polymers are parabolic curved surfaces. The novel conjugate fiber so obtained has excellent proper- ties with regard to dye acceptance, luster and touch, and is suitable for a wide range of uses such as for clothing and interior fabrics.
