Waste Minimization Avenues in the Textile Dyeing Industry.

Waste mininization and waste reduction decrease waste liability and mininze the costs associated with waste collection, handling, and treatment. Waste minimization can be an effective waste management strategy for textile dyeing operations. the wastewater volume and the concentration of chemicals used during dyeing can be reduced by caref..

Polychromatic Dyeing. Part 1. Quantitative - Multicomponent Spectroscopic Analysis.

When textile dyers attempt polychromatic dyeings they must know the strike through of each individual dye within the mixture to optimze the dyebath recipe and attain maximum processing reliability. A study based on the trichromatic dyeing of cotton with direct dyes demonstrates that it is possible to obtain the exact concentration of each..

Reply to Comments on Using Neural-Networks to Predict Dye Concentrations in Multiple Dye Mixtures.

In this letter to the editor, Warren J. Jasper responds to comments by L. Vangheluwe and associates about the importance of verification and validation of models generated using cumulative back propagation. To validate the model, Jasper used a three out or 21 way cross validation and a one out cross validation. These validations indicated..

Comments on Using Neural Newtorks to Predict Dye Concentrations in Multiple Dye-Mixtures

A paper by Warren J. Jasper demonstrates how neural networks can predict dye concentrations during continuous dyeing. Cumulative back propagtion is a commonly used neural network analysis technique that yields a complex functionasl relationship between input and output parameters. The number of weight s and bias wights in the neural netwo..

Modeling Cationic Dyeing -- Consideration of Ionic and Hydrophobic Interactions in a Modified Donnan Approach.

To determine the quantitative relationship between the dye distribution coefficient and salt concentration during cationic dyeing, the author derived a modified Donnan-model based on hydrophobic and ionic interatctions between dyes and fibers. Analysis showed that the model accurately predicated the cationic dye equilibrium absorption on ..

Single and Multibath Facilities.

Roaches Engineering's Pyrotec range of infrared heated laboratory dyeing machines has single and multibath capabilities. Two and three bath models process a number of samples simultaneously at varying volumes and temperatures. An online computer controls the processing conditions, which permits the simulations of production processes. The..

The Dropper prepares controlled solutions and calculates dyestuff color, yield, and solution variation. THe P-DOS robot sytem easures dyestuff..

Dyeing Machines of the Long Horn Series.

MCS recently introduced two new dyeing machines: the Lon Horn M and Hera. Both machiens have incresed kettle diameters and achieve larger dyeing capacities with production amounts of up to 200 kilograms perrope and up to six ropes. The Long Horn M uses the jet/flow principle, which offers maximum flexibility when processing different mate..

Small Batch Dispensing.

Datacolor International's Formula Moving Valve Dispensing System (MVDS) is a small batch dispensing system for dyes. The system is notable for its speed and high level of precision and flexibility. Central to its design is the dispensing head, which contains three flow rate mocrovalves that are pneumatically positioned and controlled. The..

Compact Dispenser and Solution Maker.

Datacolor International recentaly introduced the DS5-32, a compact gravimetric dispenser and solution maker for small dyehouses that use a limited range of dyestuffs. The DS5-32 can store up to 30 dye or auxiliary solutions in 1 liter glass bottles and automatically dispenses recipes to an accuracy of 0.02 gram. On average, the DS5-32 tak..
