Spinning pack for wet spinning bicomponent filaments

A rectangular spinning pack for wet spinning bicomponent acrylic filaments comprising thin metal rectangular plates arranged side by side, said plates comprising:

• a. a pair of end plates
• b. a plurality of first and second spacer plates, each having a central cavity and an opening in the top edge thereof leading to said central cavity, said central cavity being a distance X from the bottom edge thereof;
• c. a plurality of capillary plates, each having a plurality of slots extending inwardly from the bottom edge thereof a distance greater than said distance X;
• and
• d. a plurality of divider plates, each having slots corresponding in number and shape to the slots of said first and second capillary plates except that the slots extend inwardly from the bottom edge thereof a distance less than said distance X;
• said spacer, capillary and divider plates being arranged between said pair of end plates such that the order thereof is first spacer plate, capillary plate, divider plate, capillary plate and second spacer plate, whereby said slots in said capillary and divider plates define orifices, means for forcing a first acrylic polymer solution through said orifices via said openings and said cavities in said first spacer plates and means for forcing a second acrylic polymer solution through said orifices via said openings and said cavities in said second spacer plates.
