Get this from a library. Identification of dyes on textile fibres. [Ellis Clayton]. Identification of textile fibers is an important text for forensic scientists, police and lawyers who may be involved with the use of textile fibers to provide evidence in criminal cases.

It will also be relevant for textile designers, technologists and inspectors wishing to assess fiber quality and understand fiber damage. Identification of dyes on textile fibres and detection of metals in fibrous materials, dyes and organic pigments.

Bradford, Yorkshire, Society of Dyers and Colourists [] (OCoLC) Document Type: Book: All Authors / Contributors: Ellis Clayton. textile processes have been introduced providing unique methods to form yarns and textile substrates of widely varying structure and properties.

This book addresses itself to the structure and properties of textile fibers, dyes, and finishes and the processes used in fiber, yarn, and substrate formation and in dyeing and finishing of these.

Representative samples of textiles taken from Ottoman costumes were chemically analyzed for dyes identification purpose. The collection dates from the 19th century and belongs to the Museum of Jordanian Heritage. The chemical analyses were carried. DYES A dye is substance which at least during stage of its application has inherent affinity for the textile material.

Dyes are soluble in the dyeing medium during or at least in some stage of the dyeing process. Dyes can diffuse into fibres and interacts with the polymer structure of the fibre. All textile dyes are organic chemical sythesised from coal tar chemicals. Disperse dyes and dyeing cellulose acetates Disperse dyes and their mechanism of dyeing.

Description of the methods of application, including diazotization and coupling on the fibre. Fastness properties of disperse dyes and gas fading. Reactive dyes Reactions of cyanuric chloride and the chemistry of reactive dyes. 1. Direct Dyes This test of direct dye holds valid for both cotton and silks.

A mg portion of the dyed sample is placed in a 35 ml test tube, ml of water and to 1 ml of conc. ammonia are added and the mixture is boiled in order to bleed off a sufficient amount of dye for redyeing a piece of white cotton cloth. In spite of this, metal-complexed dyes, especially chromium premetallised dyes, are commercially important to produce bright, wash-fast shades on natural protein and polyamide fibres without the risk of overdyeing and degradation of fibre.

Textile fibers are a key form of trace evidence, and the ability to reliably associate or discriminate them is crucial for forensic scientists worldwide. While microscopic and instrumental analysis can be used to determine the composition of the fiber itself, additional specificity is gained by examining fiber color.

This is particularly important when the bulk composition of the fiber is Cited by: Title: Microsoft Word - Identification of dye classess on Author: JAHIR VI Created Date: 11/21/ PM.

Dye-substrate affinity. Dyes containing one or more azo groups (i.e. azo dyes) comprise by far the largest family of organic dyes. Prominent types are 1) acid dyes for polyamide and protein substrates such as nylon, wool, and silk; 2) disperse dyes for hydrophobic substrates such as polyester and acetate, and 3) direct and reactive dyes for cellulosic substrates such as cotton, rayon.

The identification of fibers is important to the textile industry, forensic science, fashion designers and historians among others. Identifying fibers involves observing the physical and chemical properties of the fiber for which there are a wide diversity of instruments available. This book.

The list does not include examples of fibers from two (or more) generic classes of polymers spun into a single filament. Additional information on fiber types and trademarks is given in Refs (1, 2, and 3). The reduced dye is applied to the fabric, and then exposed to the air which oxidizes he dye back to its colored form.

Physico-Chemical Aspects of Textile Coloration provides a comprehensive treatment of the physical chemistry involved in the dyeing of the major types of natural, man-made and synthetic fibres with the principal types of dye.

The book covers. Forensic analysis of fluorescent brighteners, dyes and textile fiber degradation by capillary electrophoresis, liquid chromatography/mass spectrometry, and ultra performance liquid chromatography E. Mandel sensitivity applied to analytical method performance comparisons.

Basic dyes - usually water soluble cationic dyes that are mainly applied to acrylic fibers, but find some use for wool and silk.

Azo dyes - addition of the 2 components to make the azo dye directly on or within the fibre; Direct dyes - applied to cotton, paper, leather, wool, silk and nylon.

in. Fiber identification generally involves taking samples from the artifact and viewing them at times or greater magnification to study the fiber morphology. Stains are often employed to accentuate features and to determine pulping processes. Fiber identification, especially in the case of samples from paper, is not necessarily straightforward.

The identification of fibers is important to the textile industry, forensic science, fashion designers and historians among others. Identifying fibers involves observing the physical and chemical properties of the fiber for which there are a wide diversity of instruments available. This book provides a comprehensive review of fiber structure, the diversity of instruments available to identify.
