Abstract:
A polyvinyl alcohol fiber that can easily be fibrillated at a low manufacture cost is provided. The readily fibrillative polyvinyl alcohol fiber contains a polyalkylene oxide in addition to a polyvinyl alcohol. A mass ratio of the polyalkylene oxide ranges from 3 to 40% relative to the total mass of the polyvinyl alcohol and the polyalkylene oxide. A method for manufacturing the polyvinyl alcohol fiber is also provided.
