Preparation and Study of Polyvinyl Alcohol Fiber

Abstract:

The preparation of polyvinyl alcohol fibers mainly consists of three steps: 1. The polymerization of vinyl acetate. Need the preparation of vinyl acetate and polymerization of vinyl acetate. The polymerization of vinyl acetate uses acetylene method and ethylene method.2. Preparation of PVA. Mainly to let the polyvinyl acetate taking alcoholysis reaction to the effect of methanol or sodium hydroxide. 3. Preparation of polyvinyl alcohol fiber. Complete dope preparation through washing and dehydration, dissolving, mixing, filtering and deaeration, and uses the dry, wet two methods to form the spinning. Finally, through the follow-up processing, to accomplish the preparation of polyvinyl alcohol fiber. Water soluble and high concentration polyvinyl alcohol fiber ‘s performances are fine and is application widely.
