Producing cellulose diacetate fiber

Producing cellulose diacetate fiber

A process for producing cellulose diacetate fibers superior in yarn tenacity, which comprises preparing a spinning solution by dissolving cellulose diacetate in a mixture of methylene chloride and methanol to give a viscosity of 2200 to 4000 poises as measured at 25 DEG C by the ball fall method, an...

Zusammenfassung:A process for producing cellulose diacetate fibers superior in yarn tenacity, which comprises preparing a spinning solution by dissolving cellulose diacetate in a mixture of methylene chloride and methanol to give a viscosity of 2200 to 4000 poises as measured at 25 DEG C by the ball fall method, and subjecting the spinning solution to dry spinning.
