REMOVING COLOR FROM DYEHOUSE EFFLUENT.

Archaeus Tchnology's treatment system uses Arcasorb to remove soluble color from dyehouse effluent. Arcasorb, a granular meterial based on a natrually occurring polymer, is especially effective ofr removeing reactive dyes from effluent. Raw effuent flows initlally through a prefilter. The effluent passes from the filter to the Arcasorb D ..

MEASURING COLOR-MATCHING FUNCTIONS. PART 1.

The Munsell Color SCience Laboratory at the Rocheseter Institute of Technology developed a model for the determination of color-matching functions. The model was used to design a visual colorimeter. The colorimeter utilzed laser primaries and was improved to include CRT primaries and seven interfaerencd filters that simulated daylight in ..

IMPREGNAION SYSTEM FOR AUTOMOTIVE NEEDLEFELTS.

Texicon's Autofoam system impregnates needlefelt fabric sfor use in the autombile in dustry. The system can be installed as part of a larger, more complete production line. Autofoam makes it easy to control the penetration of the binder into the mass of fibers. The foam is produced by a double rotor water-cooled dynamic foam genertor. App..

SHORT RUNS AND CONTINUOUS DYEING -- CONFLICT OR OPPORTUNITY ?

A challenge facing the continuous dyer is the ability ot meet today's fashion demands for short runs and quick responese. Advances in machinery. processes, and dyestuff now enable efficient production of short lots in continuous dyeing plants. Developments in machinery have occurred in color preparation system, quick-change padding equipm..

EARLY AMERICAN TEXTILE DYER -- CHEMIST AND ENTREPRENEUR.

The history and developemtn of dyeing and the dyeing industry during the 17th, 18th, and early 19th centureis in the United States are reviewed. Three principle operations are considered: dyeing preparation, color application, and finishing. The technology of the typical dyehouse and the types of dyes and chemicals used are discussed. Met..

EFFECT OF YARN DENSITY ON DIFFUSTIONOF p-AMINOAZOBENZENE IN MULTIPLE LAYERS OF NYLON FABRIC.

The diffusionof p-aminoazobenzene dye into multiple layers of fabric was studied in four plain weave nylon fabrics. Varying the pick spacing altered the yarn density of the fabrics. By approximating the apparent diffustion coefficient and the diffustional boundary layer parameter, the experimental data fit the teoretical curve of concentr..

BLIND DYEING -- THE WAY AHEAD.

The Society of Dyers and Colorists Midlands Symposium attracted one of its largest audiences in recent years due to the growing interest in blind dyeing or right-first-time (RFT) dyeing. Participants of the conference discussed several topics related to blind dyeing techniques that may help dyers to cope with the greater emphasis on value..

OPTIMIZATION OF PROCESSING OF COTTON KNIT GOODS.

To remain competitive in the international market, india's textile dyers will have to modernize their machinery and implement right-first-time (RFT) production methods, especially for batchwise dyeing of cotton knit goods. In India, cotton knit goods continue to be winch dyed. This method consumes tremendous amounts of water, dyestuffs, a..

COLOR CORRECTLY CONVEYED.

The perception of color depends on the light source, the object, and the visual system. Because of these variables, it is difficult to communicate color. The Hong Kong Productivity Council's computer-aided color communication system for designers and dyers replaces the old method of passing color samples back and forth between the designe..
