GLOBAL COLOR MANAGEMENT

Since the beginning of 1989, Datacolor color management systems have been installed in Tootal Thred's main manufacturing dyehouses. The Tootal Group supplies thread from manufacturing units in more than twenty countries to customers in over sixty countries. The strategy of the company has been to produce gray thread in such low-cost areas..

ECONOMICS OF DYEING

In Surat, where small process houses manufacture manmade textiles, conditions are ripe for improvement in quality standards, cost competitiveness, and pollution awareness; the industry is not yet ready to support batch-to-batch reproducibility of first-time-right dyeings. The industry must invest in automation, computerized process contro..

COLOR COMBINATIONS--WHAT GIVES?

An overview of color science emphasizes the relation of this science to the dyeing of textiles. Basic terms, such as hue and shade, are defined. Colors classified as warm or cool, light or dark, and vivid or dull are purported to have specific effects on human emotions. Colors are combined to achieve order or disorder as a result of compl..

USE OF SOLVENTS IN THE DYEING OF CELLULOSIC FIBERS.

In order to conserve water, methods of dyeing cellulosic fibers using a non-aqueous system are studied. The effect of ethanol on the sorption of direct dyes on the fibers was examined. At high percentages, ethanol increases the degree of the association of the dye. The sorption of the aggregated dye also increases. 25 refs.

METHODS OF HIGH-SPEED MONOCHROMATIC DYEING OF CELLULOSE ACETATE-POLYESTER FABRICS.

Methods of monochromatic dyeing that are based on attaining an approximately equal accessibility of cellulose acetate and polyester fibers are described. The leveling of sorption activity of fibrous blend fabrics attained, with variation, a degree of superheating of azeotropic blend vapors. Monochromatic dyeing was produced as a result of..

POSSIBILITIES OF IMPROVING THE ECOLOGIC ACCEPTABILITY OF WASHING PROCESSES FOLLOWING REACTIVE DYEING.

The problem of waste resulting from reactive dyeing processes may be mitigated by in situ removal of hydrolysates formed from the dyes. The conventional afterclearing procedure must be improved to achieve this aim. For example, the temperature may be increased in the first bath in order to concentrate the hydrolysates. The pollution load ..

COMPARATIVE TESTS OF DYE ADSORPTION FOR COTTON ON COAL AND ALUMINA.

Adsorption is used to separate organic dyes in aqueous solutions, but the process has to be modified to increase the amount adsorbed at lower cost. The adsorption of both reactive dyes and deoxidants, both used in cotton mills, were studied from aqueous solutions onto activated carbon and alumina. Conductometry and spectrophotometry were ..

KERCHIEF COTTON FABRICS OF IMPROVED WEARABLE CHARACTERISTICS.

A technique for the impregnation of brown kerchief cotton fabrics that facilitates an intensive green coloration and improves wearability characteristics is described. Coloration is attained by means of a synthesis of mineral pigments in the thread. Subsequent paraffin-stearin treatment with the fixing of aluminum to sulfate waterproofs t..

PROVIDING SPECIFICATIONS FOR ACCURATE COLOR REPRESENTATION IN TEXTILES.

In response to the need for a color selection, matching, and control system, Pantone has developed a standardized palette of 1225 colors specifically designed for reproduction with opaque colorants. This Professional Coloring System, based on regulated, quality-controlled colors, is contained in two comprehensive reference manuals. One id..

WATER -- THE PRODUCT MOST WIDELY USED AT THE AZETA FINISHING AND DYEING PLANT.

Water is a critical component in every finishing and dyeing operation at the Azeta plant in Biella, Italy. The interaction of water, heat, and wool fiber is examined. For example, dimensional stability is achieved fabric fixation, steaming, and decating, thus producing optimal fabric handle and wearability. Control of humidity, temperatur..
