The history of alum mineral processing was reviewed to emphasise on the heritage knowledge inherited by current trends in fashion technology and textile engineering. The review will also demonstrate the conservative environmental preservation nature of alum mineral as mordant. The need for modern evaluation of natural dyes and mordants will be highlighted. Keywords: Alum; Mordant; Industrial heritage Introduction the calcined mass the calcined shale was barrowed to a series Alum was known as one of the most imperative components of stone leaching pits nearby with typical dimensions of 9 x of textile industry before the introduction of chemical dyes in 4.5 x 1.5m. Fresh liquid was added to the leaching tanks and the process repeated for several weeks. The waste solids were alum quarrying and trade in several geographical areas [1]. In the 1850s. Its significance could be explored when studying the literature, interesting notes on alum as a mordant for textile liquor from leaching rose to 1.12, indicating 12 tons of dissolved dyeing of yarn, cloth and leather in North America, China, Libya, eventually dug out and discarded. -

Tegeran dyes gives deep yellow color in cotton and silk batik with good fastness properties, but rarely reported about its result quality using different type of solvents in extracting process. Therefore, we conducted this research to find out how much different type of solvent in extracting process giving influence on dyeing result quality of silk batik. In this research has been carried out Tegeran wood extraction using four different solvent such as alcohol 70%, aquadest, acid/acetic acid solution pH 2.5 and alkaline/sodium hydroxide solution pH 12. The extract then used to dye batiked silk fabric. Tegeran wood extract coloring result in silk batik giving range colour from yellow to deep cream. The color strength values obtained were batik fabric dyed with Tegeran wood extract from alcohol 70% solvent 0.49, acid 0.57, aquadest 1.15, and alkaline 1.78. From color difference testing results, we obtain value of batik fabric colored with tegeran wood extract from alcohol 70 % L*=79.34, a*=6.37, b*=53.51; aquadest L*=87.91, a*=-0.69, b*=34.53; alkaline L*=76.06, a*=9.41, b*=14.76; and acid L*=77.70, a*=8.21, b*=36.72. -

Removal of Acid Blue 25 Dye by Using Dried Water Hyacinth from Aqueous Solution
REMOVAL OF ACID BLUE 25 DYE BY USING DRIED WATER HYACINTH FROM AQUEOUS SOLUTION A thesis submitted in the the fulfillment of the requirements for the award of the degree of Bachelor of Chemical Engineering Faculty of Chemical Engineering & Natural Resources Universiti Malaysia Pahang iv ABSTRACT Water hyacinth (Eichhornia crassipes) is a free floating aquatic weeds that robustness in its growth used as an adsorbent to remove Acid Blue 25 dye from aqueous solution. The parameters studied include the adsorbent dosage, initial dye concentration, pH, and also contact time in a batch adsorption process at room temperature 21ºC. The results shows the optimum conditions for each parameter studied, adsorbent dosage at 0.60 g, initial concentration 400 mg/L, pH 2 and 100 minutes contact time. The samples after the dye uptake were analyzed by using UV-Vis spectrophotometer. Furthermore, before and after the experiments, FTIR analyses were studied to know the functional groups of the water hyacinth. In addition, the equilibrium data fitted well pseudo-second order kinetics, Langmuir and Freundlich isotherm. The maximum sorption capacities for Langmuir equation were 83.33 mg/g whereas the amount of n for Freundlich is favourable. While for pseudo-second-order kinetics, it has a low error for equilibrium sorption capacity for experimental and calculated values. This study is favourable and economically feasible for the removal of Acid Blue 25. v ABSTRAK Keladi bunting merupakan gulma air yang mengambang yang digunakan sebagai adsorben untuk menyingkirkan pewarna Asid Biru 25 dari akuas larutan.

Eosin Staining
Science of H & E Andrew Lisowski, M.S., HTL (A.S.C.P.) 1 Hematoxylin and Eosin Staining “The desired end result of a tissue stained with hematoxylin and eosin is based upon what seems to be almost infinite factors. Pathologists have individual preferences for section thickness, intensities, and shades. The choice of which reagents to use must take into consideration: cost, method of staining, option of purchasing commercially-prepared or technician-prepared reagents, safety, administration policies, convenience, availability, quality, technical limitations, as well as personal preference.” Guidelines for Hematoxylin and Eosin Staining National Society for Histotechnology 2 Why Do We Stain? In order to deliver a medical diagnosis, tissues must be examined under a microscope. Once a tissue specimen has been processed by a histology lab and transferred onto a glass slide, it needs to be appropriately stained for microscopic evaluation. This is because unstained tissue lacks contrast: when viewed under the microscope, everything appears in uniform dull grey color. Unstained tissue H&E stained tissue 3 What Does "Staining" Do? . Contrasts different cells . Highlights particular features of interest . Illustrates different cell structures . Detects infiltrations or deposits in the tissue . Detect pathogens Superbly contrasted GI cells Placenta’s large blood H&E stain showing extensive vessels iron deposits There are different staining techniques to reveal different structures of the cell 4 What is H&E Staining? As its name suggests, H&E stain makes use of a combination of two dyes – hematoxylin and eosin. It is often termed as “routine staining” as it is the most common way of coloring otherwise transparent tissue specimen. -

Colour and Textile Chemistry—A Lucky Career Choice
COLOUR AND TEXTILE CHEMISTRY—A LUCKY CAREER CHOICE By David M. Lewis, The University of Leeds, AATCC 2008 Olney Award Winner Introduction In presenting this Olney lecture, I am conscious that it should cover not only scientific detail, but also illustrate, from a personal perspective, the excitement and opportunities offered through a scientific career in the fields of colour and textile chemistry. The author began this career in 1959 by enrolling at Leeds University, Department of Colour Chemistry and Dyeing; the BSc course was followed by research, leading to a PhD in 1966. The subject of the thesis was "the reaction of ω-chloroacetyl-amino dyes with wool"; this study was responsible for instilling a great enthusiasm for reactive dye chemistry, wool dyeing mechanisms, and wool protein chemistry. It was a natural progression to work as a wool research scientist at the International Wool Secretariat (IWS) and at the Australian Commonwealth Scientific Industrial Research Organisation (CSIRO) on such projects as wool coloration at room temperature, polymers for wool shrink-proofing, transfer printing of wool, dyeing wool with disperse dyes, and moth-proofing. Moving into academia in 1987 led to wider horizons bringing many new research challenges. Some examples include dyeing cellulosic fibres with specially synthesised reactive dyes or reactive systems with the objective of achieving much higher dye-fibre covalent bonding efficiencies than those produced using currently available systems; neutral dyeing of cellulosic fibres with reactive dyes; new formaldehyde-free crosslinking agents to produce easy-care cotton fabrics; application of leuco vat dyes to polyester and nylon substrates; cosmetic chemistry, especially in terms of hair dyeing and bleaching; security printing; 3-D printing from ink-jet systems; and durable flame proofing cotton with formaldehyde-free systems. -

Jasper Graduate Students: M. S. Arora, C. E. Bright, R. P. Joshi, M. R. Lefeber Wallace, J. T. Merritt. Industrial Collaborator: W. Hunter (Cotton Inc.). Goals: The overall objective of this project is to optimize batch-dye process control by monitoring dyebaths, and by understanding and controlling the state of the dyeing process, both in the laboratory and commercial dyeing machines. Specific objectives are to: 1. Educate graduate students and advance dyeing knowledge and technology. 2. Develop neural network/fuzzy logic control for dyebath monitoring and colorant formulation. 3. Develop control systems and strategies for closed loop control via dosing, fuzzy logic and neural networks. 4. Comparatively evaluate control strategies and the absolute levels of control possible. 5. Develop useful theoretical kinetic and thermodynamic models and generic process models. Abstract: This report describes our (Dye Applications Research Group, DARG) recent progress in real-time monitoring, modeling, and controlling batch dyeing processes. The flow injection analysis (FIA) system was modified to allow injection of a small volume of dyebath into a high performance liquid chromatograph (HPLC). This FIAIHPLC system is being used to study four different procedures for exhaust dyeing cotton with reactive dyes. Data are reported for isothermal dyeings at different temperatures. Preliminary work to develop a spectrophotometric method for monitoring exhaustion of vat dyes, especially indigo, is reported. Calibration models developed from indigo powder and indigo paste under a nitrogen atmosphere indicate significant differences in the purity of the dye in these two forms. -
