Polyvinyl alcohol-based hollow fiber membrane and process for producing the same |
摘要 |
A polyvinyl alcohol-based hollow fiber membrane having a ratio between the size of particles of 90% rejection and that of particles of 10% rejection of not more than 5, thus proving to have a sharp fractionating property, is produced by a process which comprises, on producing a polyvinyl alcohol-based hollow fiber membrane by dry-jet wet spinning or wet spinning, using a spinneret having heat insulating structure.
