Apparatus for spinning different colored filaments from a single spinneret

A spin pack for spinning mixed filament yarn from at least three components comprising:

• means for receiving three or more mutually separated molten polymer streams;
• a spinneret having at least one backhole and, and for each backhole, a fiber extrusion orifice in fluid flow communication therewith, at least one of said at least one backhole being an active backhole in fluid flow communication with said receiving means;
• upstream of said spinneret, a distribution device in fluid flow communication with said receiving means and having means for distributing said mutually separated molten polymer streams to said spinneret wherein each mutually separated molten polymer stream is accessible at every existing backhole;
• and
• intermediate said spinneret and said distribution device, a selection assembly having means for selecting which one stream from anyone of said mutually separated molten polymer streams flows into which active backhole.
