Leuco Potential
The potential at which a VAT dye leuco body begins to be oxidized and precipitated.
Cohesive Energy
The amount of heat absorbed by 1mol of material to vaporize and sublimate.
Direct Printing
Directly print printing paste of various colors on white or colored textile fabrics to form printing patterns.
Rheological Property
Under shear stress action, the flow deformation characteristics of an object.
Tinting Strength
The ability of a pigment to give color to the colored base material by its own color.
Adsorption Isotherm
Distribution curve of the dye concentration on the fiber and the dye concentration in the dye solution at constant temperature dyeing equilibrium.
Curve of Dyeing Rate
Dying under constant temperature condition, dye concentration or dyeing rate on the fiber is taken as the vertical coordinate, and the dyeing time is taken as the horizontal coordinate.
Salt Effect
Use salt to control the dyeing process of direct dyes. The mechanism of promoting dyeing: Sodium ion in neutral electrolyte combines with the negative charge of fiber, so that the charge repulsion of fiber and dye decreases, the activation energy decreases, and the dyeing rate increases.
Fixing Rate
The total amount of dye covalently combined with fiber accounted for the percentage of the total amount of dye input.
