Abstract


The article introduced a new type of synthetic fiber of milk synthesis, physical properties, application performance and the advantages and disadvantages and the dyeing theory at home and abroad.In the study of milk fibers dyeing thermodynamics, linear regression analysis is made between dye liquor concentration and absorbance. Cationic Dyestuff Red X-GRL、Cationic Dyestuff Yellow X-GL、Cationic Blue GRRL、Weak-Acid Dyestuff Red 2R、Weak-Acid Dyestuff Yellow 4R and Weak-Acid Dyestuff Blue are used to dye milk fibers Under different conditions. Dye residue absorption is measured and the concentration of dye liquor is calculated by linear regression equation .drawing the adsorption isotherms and discussing adsorption isotherms after that obtaining dye fiber affinity, thermal and dye staining thermodynamic parameters. In the end analyzing dyeing mechanism of Cationic Dyestuff on milk fiber and Weak-Acid Dyestuff on milk fiber dyeing mechanism.In the study of milk fibers dyeing thermodynamic, Cationic Dyestuff Red X-GRL,、Cationic Dyestuff Yellow X-GL and Cationic Blue GRRL are used to dye milk fiber. Dyeing percentage is measured and dyeing rate curve is drew at different temperatures or adding different types of surfactants when the Cationic Dyestuff takes up milk fiber. Kinetic parameters such as diffusion coefficient, balanced dyeing percentage, half-dyeing time and dyeing rate constant of Cationic Dyestuff dyeing milk fiber was obtained. The dyeing speed of Cationic Dyestuff on Acrylic and milk fiber is contrasted. In the end a diffusion model about Cationic Dyestuff and Weak-Acid Dyestuff dye milk fiber was proposed.Some dyeing of basic data of milk fiber is obtained and the dyeing theory through the study of the subject is supplemented.
