    A sustainable and hydrolysis-free dyeing process was developed for polylactic acid (PLA) fibers. PLA is a biobased alternative to petroleum based polyethylene terephthalate (PET), which is the most widely used textile fiber. However, the hydrolytic degradation of PLA fibers under the conventional aqueous dyeing conditions limited its applications in textile by: conditions will destroy the reuse physical strength properties of cotton.

Investigation of textile dyebath reconstitution and reuse. Research Triangle Park, NC: U.S. Environmental Protection Agency, Industrial Environmental Research Laboratory ; Cincinnati, OH: Center for Environmental Research Information [distributor], (OCoLC) Material Type.

CiteSeerX - Document Details (Isaac Councill, Lee Giles, Pradeep Teregowda): Over billion gallons of wastewater are discharged annually in the United States from the finishing of textile products. It is estimated that about 80 percent of textile finishing mills discharge their wastewater to publicly owned treatment works (POTW).

Most of. Fact sheet on an analysis system for dyebath processes in the carpet manufacturing industry written for the NICE3 Program. The Georgia Institute of Technology (G.I.T.) has developed an effective automated dyebath analysis and reuse system that improves the energy, environmental, and economic performance of dyehouse batch operations.

The new system enables dyeing solutions to be Author: P. Simon. of the spent dye liquor, (ii) clean-up and reuse of the spent dye liquor, and (iii) reconstitution and reuse of the spent dye liquor.

The objective of this work was to investigate the possibility of obtaining a series of dyeings in a number of different colors, by reconstituting and reusing the spent dyebath after each dyeing.

The system chosen for. Dyebath reuse has been systematically investigated as a viable low capital modification of batch dyeing processes to reduce the volume of water required, the quantities of chemicals discharged and. The feasibility of reconstitution and reuse of an acid dye dyebath for wool dyeing with different dye concentrations was studied.

The residual dyebath was analyzed and reconstituted to the. Evaluation of Water Reuse Technologies for the Textile Industry. A pilot scale study of dyebath reuse was conducted using ten commercial dye shades. of the scientific investigations were.

In a typical textile dyeing process, more than 80% of the salt and 90% of the color is discharged with the dyebath and first rinsing bath. In the study, the wastewater was divided into two parts, one (COD concentration of over mg/L) was discharged into the wastewater treatment plant; the other (COD concentration of less than mg/L Cited by: Contents Contributorcontactdetails xiii WoodheadPublishingSeries in Textiles xvii Parti General aspects of dyeing 1 1 Fundamentalprinciplesofdyeing 3 ,UniversityofLeeds,UK Introduction 3 Principlesofdyeing 3 Exhaustdyeing 4 Continuousdyeing 6 Printing 7 Classificationsystemsfordyes 8 Classificationofdyesbydyeclass 11 Conclusion 25 File Size: KB.

Successfully decolour dyebath wastewater (about 90%) Reused treated water in textile pretreatment bath. Got optimum whiteness, absorbency,lower strength and weight losses of pretreatmented.

Dyebath reuse in polyester fiber dyeing was explored. Exhausted hot dyebaths were examined to determine the concentration of residual colorants, replenished, and reused to dye more batches.

Water Conservation Through Automated Dyebath Reuse. By James L. Clark. Abstract. Proceedings of the Georgia Water Resources Conference, March, Athens, e wet processes, particularly batch dyeing and finishing, consume vast quantities of water, posing significant demands on the water resources in regions where the Author: James L.

Clark. The absorbance of the dyebaths was measured at various wavelengths and the results are summarized in Table photographs of dyed linen fabrics and the spent dyebath are presented in Fig. absorbance of the dyebath at all wavelengths showed an insignificant reduction after the first dyeing cycle, thus indicating the possibility of reuse of spent dyebath for further dyeing without loss Cited by: 4.

commercial reuse depends on an automated analysis system that precisely analyzes dyebath samples in real-time and provides for reconstitution and reuse. If fully implemented throughout the carpet industry, this innovation is expected to reduce energy consumption by trillion Btu/year. Waste and cost savings will also be : P.

If fully implemented throughout the carpet industry, this innovation is expected to reduce energy consumption by trillion Btu/year.

Waste and cost savings will also be substantial. Four AOPs have been investigated: O 3, O 3 /H 2 O 2, O 3 /UV and O 3 /UV/H 2 O the case of the O 3 /H 2 O 2 and O 3 /UV/H 2 O 2 processes, hydrogen peroxide was added to the reaction mixture before the ozone was applied.

The reaction progress for all ozone-based AOPs was stopped by the addition of M Na 2 SO 3 to the collected samples.

This is necessary both to allow an automatic control of dyeing kinetics and, especially, to enable the correct reutilization of the residual dye baths.
