Abstract:
A nozzle for making a reinforced hollow fibre membrane discharges one or more reinforcing yarns at or near a plane where the dope exits the nozzle, or in the same plane as a discharge opening of dope passage, or both. Multiple discrete yarn discharge openings may be spaced around a longitudinal axis of the nozzle. A reinforcing yarn passage remains generally free of dope during use. The dope may be discharged in an annular ring inside of the one or more reinforcing yarns, in an annular ring outside of the reinforcing yarns, or both. Minimal tension is required to pull the yarns through the nozzle, which helps to reduce distortion of the membrane cross section in a coagulation bath.
