A Practical Guide to Microbead Media Selection.

The use of microbead agitator mills for the micronizing and dispersion of paints, printing inks, and dyes, as well as other wet grinding applications, requires the proper selection of grinding media. The correct medium increases milling production, reduces power consumption, limits mill wear, and lowers grinding media consumption. A corre..

Dye from Gulmohr Flowers.

Researchers developed a dye for silk based on the red flowers of the gulmohr tree, which grows throughout the tropics. An acidic extraction method and post mordanting produced good shades. The optimal concentration for dyeing was 3 grams of gulmohr flower in 100 milliliters of water containing 1 percent hydrochloric acid. Optimal dye extr..

The Functions and Limits of Direct Dyes in the Finishing Process

Direct dyes offer such advantages as bright colors, lightfastness, dyeing stability at 130 degrees centigrade, reduced dyeing times, and excellent dye penetration. Fixing agents ensure dye fixation to the functional groups of the fiber to prevent migration and develop fastness. Ciba offers three groups of nonformaldehyde fixing agents tha..

Application of Magnetically Treated Water to Dyeing of Wool and Woollen Fabrics.

The physical properties of water passed through an electromagnetic or magnetic field can be controlled so that water can be prepared for a particular technological process. Researchers investigated the use of water treated with a magnetic field for dyeing woolen fabrics. Woolen fabrics dyed with magnetically treated water exhibited an inc..

Fibrillation Tendency of Lyocell and Its Modification by Reactive Dyeing

A decrease in interfibrillar cohesion renders lyocell fibers prone to wet fibrillation that can be controlled to create novel fabric surface effects. A typical processing sequence to attain peach skin effects includes open width desizing, singeing, primary fibrillation in an aerodynamic machine under alkaline wet conditions in rope form a..

Behavior Dynamics of Disperse Dyes on Polyester

An overview of disperse dye behavior during the dyeing of polyester fibers includes discussions of simplified batch dyeing, thermofixation, continuous coloration, thermomigration, colorfastness testing, the nature and distribution of disperse dyes, sorption and desorption in microfibers, carriers, leveling agents, and finishing chemicals...

Spectrophotometric Studies for Determining Binding of Disperse Dyes.

A study used spectrophotometry and Klotz's method to study the binding of disperse dyes with different chemical structures (C.I. Disperse Red 118, C.I. Disperse Violet 26, and C.I. Disperse Yellow 42) to anionic surfactant treated polyester fibers in the presence of a carrier. Each mole of surfactant bound more than 1 mole of dye, which i..
