ABSTRACT:
An apparatus and method for forming liquid spinning solution into a solid formed product whereby the solution is passed through at least one tubular passage (17) having walls formed at least partly of semipermeable and/or porous material. The semipermeable and/or porous material allows parameters, such as the concentration of hydrogen ions, water, salts and low molecular weight, of the liquid spinning solution to be altered as the spinning solution passes through the tubular passage(s).
