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. -
Staining Wood and Natural Materials Using PRO Washfast Water Based
Staining Wood and Natural Materials using PRO WashFast Water-Based Dyes Please read directions carefully before starting. Many materials, whose surface is only slightly wettable, may be colored with water-based (water soluble) dyes resulting in colored surfaces that do not hide the grain of the wood or the character of the substrate. This process is also suitable for the coloration of feathers, retouching wool tapestries and wool or nylon carpeting. Basically anything that does not have the high wash fastness requirements of wearable clothing fabrics. Wet fastness is good. Always do test samples before working on a large project. For additional information visit our web site at www.prochemicalanddye.com. Wear rubber gloves, apron, or old clothes. Utensils used for dyeing should never be used for food preparation. Procedure: 1. Dissolve the PRO WashFast Acid dye by placing 1 tsp (2.5 gm) of the dye in a one cup (250 ml) Pyrex container. Add 1 or 2 tsp (5 or 10 ml) of boiling water to make a paste. Gradually add more boiling water with continuous stirring to the 2 cup (125 ml) mark. Set aside to cool. 2. When cooled to room temperature, fill to one cup (250 ml) mark with denatured grain alcohol or Isopropyl rubbing alcohol (90%). Store in re-sealable glass container. 3. Apply to surface of substrate with foam brush or immerse object into dye solution for several minutes. Air dry and repeat procedure as often as needed for deeper color allowing previous coat to dry thoroughly. 4. After thorough drying, wood and similar materials may be coated to seal in the color and give lasting protection to the wood itself. -

Dyeing of Polyamide Fibres
Dyeing of Polyamide Fibres Polyamides • Nylon a Polyamide, it is a condensation polymers. The formation of a polyamide is same as the synthesis of a simple amide. One prominent difference is that both the amine and the acid monomer units each have two functional groups ‐ one on each side of the molecule. In this polymer, the repeating units are identical. • Nylon is made from 1,6‐diaminohexane and adipic acid by elimination of water molecules (‐H from the amine and ‐OH from acid as shown in red on the graphic). • A simple representation is ‐[A‐B‐A‐B‐A‐B]‐. Nylon 66 • Nylon 66, was discovered in 1931 by Wallace Cruthers at DuPont. It was the first fully synthetic fiber produced. It was introduced to women in nylon stockings in 1939 with huge success. During World War II, nylon production was used to make parachutes and other items needed by the military. • Nylon is very similar in structure to the protein polyamides in silk and wool as shown earlier, but is far stronger, more durable, more chemically inert, and cheaper to produce as compared to the natural fibers. Polyamide Fibres • It’s a Nylon fibre we generally know. • It consists of multiples of six carbon chains, in which half the end of carbon being converted to carbonyl and other half to imino nitrogen. • It is thermoplastic , is sensitive to heat and tension applied in various texturizing processes. • Total temperature‐tension history of yarn determines the degree of orientation in textured yarns. Dyeing of Polyamide Fibres • Acid, metal complexes, disperse reactive and disperse dyes are the important classes of dyes used in dyeing of nylon. -
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 .

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. -
Creative Designing of Fabric Patterns by Tie-Dyeing with Synthetic Dyes
www.ijird.com February, 2020 Vol 9 Issue 2 ISSN 2278 – 0211 (Online) Creative Designing of Fabric Patterns by Tie-Dyeing with Synthetic Dyes Nelima Barasa Lecturer, Department of Physical sciences, Rongo University, Kenya Francis Ongachi Olal Senior Lecturer, Department of Physical sciences, Rongo University, Kenya Abstract: Tie and dye are a resist method of fabric decoration where patterns are skillfully introduced on plain fabrics through tying and dyeing with synthetic dyes. Hot synthetic dyes were used in this study due to their advantage in terms of color variety, brightness and fastness. This study produced fabric pattern designs by tie and dyeing with hot water dyes which are good in terms of color fastness. Different types, forms, techniques, and processes of creating unique patterns by tie and dyeing was done. Basic tie-dyeing methods twisting, folding, pleating, wrapping, crumbling and sewing were then used to create new patterns when dyeing each color. Though tie and dye as a technique is familiar to many people, exploration in terms of the unique fabric patterns design has not been done especially in Kenya thus making us to get the tie-dyed fabrics from the international market. This paper therefore creatively introduced unique patterns on fabrics through folding, twisting, crumpling and tie and dye. The fabric patterns formed are very unique compared to what is available in the Kenyan market. The tie-dyed fabrics can be used in designing and developing fashion items like men’s shirts, ladies wear, ladies hand bags and scuffs. The methodology involved aims at create unique fabric patterns which was done through folding, twisting, crumpling and tying, followed by preparation of the dye bath and then dyeing the prepared fabrics. -
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. -
Real Time Analysis and Control of Batch Dyeing Processes
C95S4 Page 1 Project Title: Real Time Analysis And Control of Batch Dyeing Processes Project Number: C95-S4 PI(s): R. McGregor (Leader NCSU), K. R. Beck, G. K. F. Lee, C. B. Smith, W J. 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.
