Abstract
An apparatus and method for forming liquid spinning solution into a solid formed product. The liquid spinning solution is passed through a die assembly having a tubular passage having walls formed partly of semipermeable and/or porous material. In operation, draw down of the liquid spinning solution is performed partly within the die assembly. The semipermeable and/or porous material allows parameters, such as the concentration of hydrogen ions, water, salts and low molecular weight constituents, of the spinning solution to be altered as the spinning solution passes through the tubular passage.
