METHOD FOR POLYAMINO ACID CONJUGATE FIBER PRODUCTION BY AQUEOUS SOLUTION INTERFACIAL SPINNING PROCESS AND APPARATUS FOR CONTINUOUS SPINNING

摘要

PROBLEM TO BE SOLVED: To provide a method for spinning a water-insoluble conjugate fiber from an aqueous solution of a water-soluble polymer material, especially a polyamino acid and an apparatus for continuous spinning of fiber. SOLUTION: This method for solution interfacial spinning is characterized in that a cationic polymer electrolyte composed of especially a polyamino acid, an anionic polymer electrolyte and their aqueous solutions are used. This apparatus for polymer conjugate fiber spinning comprises a solution feed pump, an interfacial reaction tank, a dehydration bath, a winding roller and a warm-air dryer. Consequently the water-insoluble conjugate fiber constituted of two kinds of polymer electrolyte components can be spun by using only water as a spinning solvent by taking advantage of spontaneous polymer electrolyte compound material formation at a mixed interface of two polymer electrolyte aqueous solutions having mutually opposite electric charges.
