report_problem Problem Statement

Viscose/rayon is the world's largest regenerated cellulose fibre — a $23B global market. Viscose is MORE wrinkle-prone than cotton due to its lower wet strength and amorphous cellulose structure, meaning finishing with DMDHEU is almost universal for apparel end-uses (blouses, dresses, linings, shirting). The EU REACH Aug 2026 formaldehyde restriction creates an immediate compliance crisis for mills in China, India, and Indonesia exporting to European brands. Most of the world's viscose finishing happens in Asia at mills that have no commercially available formaldehyde-free alternative. CAGE's amino acid + polycarboxylic acid system enters this market exactly when Asian export mills need it most.

flag Success Criteria

WRA ≥265° (warp + fill) on viscose substrate after 5 wash cycles. Tensile strength retention ≥55% vs untreated (viscose has lower initial strength than cotton). Whiteness index maintained ≥80 on white viscose substrates. pH optimum identified for viscose substrate specifically. Zero formaldehyde release.

precision_manufacturing Equipment Needed

Padding mangle, forced-air oven, AATCC 66 tester, pH meter, whiteness meter, tensile tester, 100% viscose fabric (woven and knit variants)
