Thermodynamic Modeling of Bifunctional Dye Hydrolysis under High Shear Boundary Layer Flow
High fluid shear compresses boundary layers, accelerating hydroxyl mass transfer and driving hydrolytic dyestuff loss in bifunctional reactive dyeing.
Alkaline Ph Measurement Errors in Reactive Dye Bath Operations
Uncorrected sodium ion interference and junction drift in high-alkaline reactive dye baths distort pH readings by up to 0.6 units, causing dye hydrolysis and batch off-shade failures.
Liquid Junction Potential Errors in High-Alkali Reactive Dye Baths
Uncorrected reference junction potentials in high-alkali dye baths cause hidden pH offsets up to 0.4 units, driving dye hydrolysis and shade off-tones.
Hydrolyzed Reactive Dye Extraction Kinetics during High Cover Factor Fabric Washing
Dense fabric wash-off requires electrolyte removal below 1 g/L before 95°C soaping to extract residual hydrolyzed dye without fastness failures.
Cotton Ply Twist Multipliers in Continuous Reactive Dyeing
Yarn ply twist multiplier controls intra-bundle pore radius; multipliers above 4.0 cause surface ring-dyeing frosting while values under 3.2 provoke migration.
