Acetate and Triacetate Fibres
category
Acetate fibres are produced by esterifying cellulose with acetic acid/acetic anhydride forming cellulose acetate (2.5 acetyl groups per glucose unit for acetate, 2.9-3.0 for triacetate), dissolved in acetone, then dry-spun. Offer silk-like aesthetics, thermoplasticity, and quick-drying properties distinct from regenerated cellulose fibres.
Role
Bridge between regenerated cellulosics and synthetics, used in fashion apparel, linings, cigarette filters, and technical applications leveraging thermoplasticity and low moisture absorption.
