1.1 Chemical Structure and Polymer Style

(PVA Fiber)

Polyvinyl alcohol (PVA) fiber is a synthetic polymer originated from the hydrolysis of polyvinyl acetate, leading to a linear chain composed of repeating–(CH ₂– CHOH)– units with varying degrees of hydroxylation.

Unlike most synthetic fibers produced by straight polymerization, PVA is typically produced by means of alcoholysis, where vinyl acetate monomers are very first polymerized and then hydrolyzed under acidic or alkaline problems to replace acetate groups with hydroxyl (– OH) functionalities.

The level of hydrolysis– ranging from 87% to over 99%– seriously influences solubility, crystallinity, and intermolecular hydrogen bonding, thereby determining the fiber’s mechanical and thermal habits.

Fully hydrolyzed PVA displays high crystallinity as a result of considerable hydrogen bonding in between surrounding chains, bring about premium tensile toughness and lowered water solubility contrasted to partly hydrolyzed forms.
