In the dyeing, printing, and finishing sectors, exhibitors at OTEMAS 1993 presented various advances related to the growing use of automatic process monitoring and control. These systems, aided by microcomputers, provide increased production and improved quality. Another view of the exhibition looks at recent developments from Thies, Then..

Dwelling Bath for Pretreatment and Washing After Dyeing and Printing.

Fleissner recently upgraded the design of its auxiliary converyor dwelling bath to improve the efficiency of tis open width washing machinery. Fleissner's washing machines depend on a combination of perforated durms, cage rollers, and spray nozzles with steam-tight enclosures to prevent the escape of hazardardous vapors. The new dwelling ..

Microsample Dyeing Machine Development.

Scholl's MiniPlus range of fabric dyeing machines can process as little as 1-4 kilograms of fabric when equipped with its new Microstorage chamber insert. The Microstorage chamber sits abovethe standard storage chamber, which has a capacity of between 35 and 110 kilograms, and takes only 10 minutes to fit. The system uses the existing mai..

Dyestuff Technology for Livelihood.

Modern changes to the dyestuff industry can be attributed to would population growth and the rapid growth of the chemicals processing and fibers industries. This rapid growth has contributed to global environmental effects, including the depletion of natural resources and the greenhouse effect. Environmentally besign growth is recommended..

CHITIN REMOVES TEXTILE DYES FROM WASTEWATER

Researchers at North Carolina State University College of Textiles discovered that chitin removes color from wastewater at textile dyeing facilities. k bulk powdered form of chitin, which is polymer derived from crab sheels, acts as a filter in a laboratory decolorization module. The chitin absorbs up to 20 percent of its weight in dye. A..

ROMOVAL OF ACID DYES FROM AQUEOUS WASTEWATER SOLUTIONS. PART 5. SALTS AND TEXTILE AUXILIARIES.

Salts and textile auxiliaries influence the formation of insoluble complexes of dyes with the ligand curcurbituril. Because the salts complex with the curcurbituril, they compete with the dyes. A similar competition with surfactants is possible if parts of the surfactant molecule are located inside a hydrophobic cavity of the curcurbituri..

REMOVAL OF ACID DYES FROM AQUEOUS WASTEWATER SOLUTIONS. PART 4. USE OF LIGAND CURCURBITURIL.

The ligand curcurbituril selectively removed acid dyes from aqueous solutions. Passing the solutions through a column filled with the solid ligand effected removal. An investigation of factors influencing the formation of insoluble dye complexes determined that the chemical structure of the dye molecules and the pH of the solution were im..
