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. -

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. -
Troubleshooting H&E Stain
Melinda M. Chow, MS, HT(ASCP)CM Memorial Sloan Kettering Cancer Center Basking Ridge, New Jersey Hematoxylin & Eosin staining is the most frequent routine stain in the Mohs Micrographic Surgery tissue preparation. It has stood the test of time as the standard stain for histologic examination of human tissues since it was independently introduced in 1865 and 1875, by Böhmer and Fischer respectively. Common problems, pitfalls and troubleshooting tips. H & E is the primary diagnostic technique for evaluation of morphology in the histopathology labs. One of the best nuclear stains. H & E provides easier identification of histological features than T-blue. It is easy and simple to use. Stains are inexpensive, yet reliable and informative. It is stable and durable stain, lasting years without fading Hematoxylin is a natural dye extracted from the heartwood of logwood trees which is indigenous in Central America, Caribbean and other tropical countries. It is misleading to call hematoxylin stain as it alone does not stain. It has to convert to hematein. Hematein is what we call hematoxylin. It is a basic dye and carries a (+) charge. Affinity for basic dye is called basophilic. Hematein Chromatin (+) charge (-) charge Mordant (Al+3,Fe+3,Chr+3) This complex is held by covalent bonds Hematein-mordant-chromatin complex Courtesy of Biotek Progressive vs regressive Progressive stains are: Gill’s (I-III), Mayer’s Regressive stains are Harris's, Delafield's, Ehrlich's Progressive method : tissue is stained and stopped Regressive method: tissue is overstained Eosin is a synthetic stain It is the counterstain and acts as an acid dye. -

Theory of Staining Prepared By: Ms
Theory of Staining Prepared by: Ms. BR Tsauses Anatomical Pathology 2A (ANP611S) April 2020 Learning objectives • Understand the aims of staining • Describe why sections need to be coloured with dyes • Describe how dye bind to tissues • Understand the different types of staining • Describe the principle of the following stains; H&E Stain and PAP stain • Describe the reasons for mounting tissue Pre-learning Quiz • Please take the pre-learning quiz before proceeding with the presentation. Types of staining • Non-vital stains – staining of dead tissue that has been fixed, processed and sectioned • Vital stains – the colouring of living tissue/cells either using very dilute dyes or by the phagocytic action of macrophages ingesting dye particles. • Histochemical stains- utilizes a true chemical reaction in the tissue and matches what would happen if the reaction was performed in a test tube. Types of staining cont… • Lysochrome – the staining of neutral lipids/fats whereby elective solubility allows the dye molecules to leave the solvent and enter the lipid. • Silver Impregnation – Depositing metals onto or into tissue components. Silver is the metal most commonly employed, • Injection – the introduction of a coloured compound into the tissue to highlight various structures Types of staining cont… • Fluorochrome – staining is affected by combining a fluorochrome with a tissue entity, which is visualized under fluorescent light. • Immunostaining – staining is based on an antibody-antigen reaction whereby a labelled antibody permits the site of the reaction to be visualised. Why are stains taken into the tissue • Stain uptake due to dye-tissue or reagent-tissue affinities • Affinity – the tendency of a stain to transfer from solution onto section. -
Hematoxylin Formulae
Hematoxylin Formulae Bryan D Llewellyn Produced for distribution through StainsFile The Internet Resource For Histotechnologists http://stainsfile.info This document includes formulae for the alum and iron hematoxylin solutions included on the StainsFile Internet site. Some of these are no longer in use, and others are variations of other, more common, formulae. I have included a dis- cussion of the relationship between the dye and the mordant, and how the rela- tionship between them affects the staining character of a formula. The formulae have been collected from several sources, including older reference texts and the Internet. If any reader knows of a hematoxylin formula not listed in this document, I would most appreciate receiving details so that it may be included in the future.
