Recent Developments in Effluent Purification/Colour Stripping.

Recent developments in dyehouse technology include purification, color stripping, and minimizing and reusing dyehouse effluent. Purification of dyehouse effluent by electrochemical processes uses an electroflotation process developed by Klose Abwassertech

Colormetry-Part 5: Colour Difference Measurements and Their Use.

The CIELAB system of color difference measurement is well known in the textile industry. In the CIELAB color space, acceptability and perceptibility tolerances vary with position, or in terms of hue, chroma, and lightness. Equations proposed by the SDC Co

Recent Developments in Colour Measurement and Colour Management.

The technology for color measurement and management has improved dramatically in recent years. New spectrophotometers and colorimeters rely on computerized control and sophisticated software to achieve an unprecedented level of accuracy and reproducibility. The color measuring instruments are often components of a completely integrated co..

The Influence of Washing Powder Components on Dye Loss and Dye Fading.

Detergent manufacturers often attribute the loss of color during washing to the action of bleach. Researchers tested the validity of this assumption by examining color loss resulting from washings in detergents containing bleach and 'color safe' detergent

UV Stabilization of PET Fibers: Microscopy Study.

Researchers investigated the radial diffusion of three ultraviolet stabilizers in high molecular weight polyethylene terephthalate fibers. The study used a benzophenone derivative, a benzotriazole derivative, and a benzotriazine derivative as stabilizers.

New Technologies in Package/Piece Dyeing.

A short discussion, which is heavily supplemented by photographs, illustrations, and diagrams, reviews technical developments in package and piece dyeing technology. In package dyeing, recent innovations include the introduction of horizontal and vertical designs, automation of chemical dosing, improved process control, robotic package tr..

Extremely Rapid Heating and Cooling.

Werner Mathis produces the Micromat HT beaker dyeing machine. The machine provides for extremely rapid heating and cooling. Other features include direct dye liquor heating, and direct dye liquor temperature measurement. Microwaves used as the heat source provide for maximum heat gradients. Switching over to nozzle type water sprays suppl..

The Most Modern Technique to Process and Handle Small Lots and Products Sensitive to Tension.

Benninger designed its modular Ben-Jig dyeing machine to process small lots of fabrics, including those with a high level of sensitivity to tension. The machine is notable for its robust construction, ease of operation and maintenance, and safety. It processes rolls of fabric up to 1,000 minute. The longitudinal tension varies from 5-100 ..

Factors Affecting the Dyeability of Cotton Crosslinked with Polycarboxylic Acid.

Researchers at the Southern Regional Research Center of the United States Department of Agriculture improved the dyeing properties of cotton fabrics that were crosslinked with polycarboxylic acid by adding reactive nitrogenous additives, such as alkanolam

ITMA '95 Bleaching, Dyeing, Printing and Finishing Machinry Developments.

An overview of wet processing machinery on display at ITMA 1995 highlights increased production rates, integrated process controls, and reduced cycle times available in upgraded bleaching machines, dyeing machines, printing machines, and finishing machines from such machinery manufacturers as Benninger, Brugman, Gaston County, Krantz, Lon..
