  • ABSTRACT WANG, GUAN. Synthesis and Application of Bleach Activators
    ABSTRACT WANG, GUAN. Synthesis and Application of Bleach Activators Containing Various Cationic Groups and PET Fabric Decolorization using Fenton’s Reagent. (Under the direction of Dr. David Hinks.) CBAs are quaternary ammonium salts (QAS) that are extensively used in various applications. Although most of the QAS are generally believed to be nontoxic to humans, they will harm aquatic life both animals and plants. CBAs are applied in textile bleaching process and the wastewater after bleaching contains chemicals including bleach activators. Even though wastewater contains CBAs will be treated in a wastewater treatment plant, the treated water still contain these chemicals. The study of acute toxicity and genotoxicity of CBAs to aquatic organisms was conducted in this study. Eight new bleach activators and two bench mark cationic bleach activators were investigated. New invented cationic bleach activator 3- PBBC is 86 times less toxic in the Daphnia sp. Immobilization Test, 18 times less toxic in Algae Toxicity assay and 10 times less mutagenic in the Salmonella/microsome microsuspension assay in comparison with the benchmark product (TBBC). This confirmed that replacing the cationic group in CBAs using low toxicity ammines can reduce the toxicity of CBAs to aquatic organisms. An effective low temperature and neutral pH bleaching system was developed using CBAs. A comparison life-cycle assessment for conventional and innovational bleaching system was conducted in this study. Their relative environmental performance was analyzed and compared. Based on data from industry, pre-published research, lab-scale experiments and the Ecoinvent database, the life-cycle-inventory (LCI) for both innovative and conventional bleaching process was developed.

  • Red, Blue and Purple Dyes
    Purple, Blue and Red Dyes We have discussed the vibrant colors of flowers, the somber colors of ants, the happy colors of leaves throughout their lifespan, the iridescent colors of butterflies, beetles and birds, the attractive and functional colors of human eyes, skin and hair, the warm colors of candlelight, the inherited colors of Mendel’s peas, the informative colors of stained chromosomes and stained germs, the luminescent colors of fireflies and dragonfish, and the abiotic colors of rainbows, the galaxies, the sun and the sky. The natural world is a wonderful world of color! The infinite number of colors in the solar spectrum was divided into seven colors by Isaac Newton—perhaps for theological reasons. While there is no scientific reason to divide the spectral colors into seven colors, there is a natural reason to divide the spectral colors into three primary colors. Thomas Young (1802), who was belittled as an “Anti-Newtonian” for speaking out about the wave nature of light, predicted that if the human eye had three photoreceptor pigments, we could perceive all the colors of the rainbow. He was right. 751 Thomas Young (1802) wrote “Since, for the reason assigned by NEWTON, it is probable that the motion of the retina is rather of a vibratory [longitudinal] than of an undulatory [transverse] nature, the frequency of the vibrations must be dependent on the constitution of this substance. Now, as it is almost impossible to conceive each sensitive point of the retina to contain an infinite number of particles, each capable of vibrating

  • ABSTRACT YI, DING. a Comparison of Mordant and Natural Dyes In
    ABSTRACT YI, DING. A Comparison of Mordant and Natural Dyes in Dyeing Cotton Fabrics. (Under the direction of Dr. Harold S. Freeman and Dr. Peter J. Hauser). Mordant dyes constitute a class of synthetic colorants that are applied to textile fibers mainly through the aid of transition metal ions such as Cr3+. The resultant dye-metal complexes are key to the fastness properties produced on wool. In the same way, most natural dyes require the use of a mordant to have coloring power on textiles such as cotton. Unlike mordant dyes on wool, the fastness properties of natural dyes on cotton are generally quite low. Consequently, they have largely been replaced by synthetic dyes that are more cost effective, brighter, and more durable under end-use applications. Interest in green technologies has led to renewed consideration of natural dyes for textile coloration because they are biodegradable and do not involve manufacturing processes requiring genotoxic aromatic amines. Interestingly, such a shift would bring dyeing technology full circle to a family of colorants lacking the vibrancy and technical properties of most synthetic dyes. However, similarities between the dyeing method for mordant and natural dyes brought to mind the potential for reducing the level of synthetic dyes used commercially by combining suitable dyes from these two classes for dyeing textiles. This thesis research was devoted to stage 1 of this idea, namely the evaluation of mordant dyes as colorants for cotton fabric. With this in mind, dyes such as Mordant Blue 13, Mordant Brown 40, Mordant Orange 6 and Mordant Yellow 8 were applied to cotton using various dyeing times, temperatures, dye bath concentrations and mordants.

Among the organic pollutants are dyes that come as effluents from the textile industries. Toxic metals are the main inorganic pollutants with their sources from industries such as mining, electroplating, batteries etc. The presence of both classes of pollutants in the aquatic environment poses a serious threat to aquatic organisms and humans who depend on these waters for domestic purpose.
