Viscose Fibre Structure and Morphology
topic
Viscose fibres exhibit regenerated cellulose II crystal structure (antiparallel chains), crystallinity of 30-40%, degree of polymerization 250-350, circular to serrated cross-section (skin-core structure with denser skin), longitudinal striations, and characteristic 'Christmas tree' pattern under polarized light from irregular orientation.
Role
The relatively low crystallinity and DP result in lower tenacity than cotton but superior moisture absorption (11-14% regain), dyeability, and drape characteristics.
