| Abstract: | Four high wet modulus viscose fibres (Avril, Avril III, Prima, and Viloft) were evaluated for dye exhaustion characteristics using cotton and standard viscose fibres as standards. Dyebath exhaustion was quantified by spectrophotometry analysis. Viscose fibres, as a class, exhibited higher percentage exhaustion for all dyes studied than did the cotton fibres. Dye uptake by the viscose fibres varied, highlighting the need for further research to enable the effect of differing dye classes or differing control fibres to be studied. Viscose fibres may vary in dyeability from one producer to another due to differences in fibre cross-section, skin-to-core ratio, molecular orientation or pore size. |
