TLDR
Using UV-visible range microspectro-photometry (MSP) spectra, the degree of spectral variation and consequent discriminating power of MSP varied according to the dye class, from 0.13 for sulphur dyes to 0.93 for reactive dyes.About:

Journal ArticleDOI
Forensic analysis of dyed textile fibers
TL;DR: This review will focus on more recent methods for comparing fiber color by using chromatography, spectroscopy, and mass spectrometry, and the increasing use of multivariate statistics and other data analysis techniques for the differentiation of spectra from dyed fibers.
Journal ArticleDOI
Blocks of colour IV: the evidential value of blue and red cotton fibres.
TL;DR: The very high discriminating power using a combination of light microscopy, fluorescence microscopy and UV/VIS microspectrophotometry shows that even blue and red cotton fibres can provide excellent evidence when involved in fibre transfer cases.

TL;DR: It is shown that it is possible to detect the presence of dye in fibres with concentrations below that detectable by the traditional methods of light microscopy and microspectrophotometry and Raman spectroscopy.

A textile fibre survey as an aid to the interpretation of fibre evidence in the Sydney region
TL;DR: Frequency figures of the fibre population on textile cinema seats were measured in Sydney, Australia, in winter to emphasise the significance of fibres as evidence of contact.
Journal ArticleDOI
The discrimination of (non-denim) blue cotton.
TL;DR: The degree of discrimination obtained between non-denim blue cotton fibres using visible-UV range microspectrophotometry alone was found to be high, similar to that reported by a previous study where this method was combined with light and fluorescence microscopy.

Forensic examination of fibres
TL;DR: In this paper, the collection and recovery of fibres from crime scenes, laboratory aspects contamination classification, and fibres structure and composition microscopic examination are discussed, including fibres colour analysis, thin layer chromatography colourant analysis, high performance liquid chromatography infra-red spectroscopy pyrolysis gas chromatography pryloysis Gc-mass spectrometry miscellaneous examinations.

The Analytical chemistry of synthetic dyes
TL;DR: The chapter likely to be of most value to the paint industry is that on the identification of organic pigments on substrates other than textile fibers.

An Assessment of the Value of Blue, Red, and Black Cotton Fibers as Target Fibers in Forensic Science Investigations
TL;DR: In this article, the value of non-denim blue, red, and black cotton fibers as evidence was evaluated using comparison microscopy, microspectrophotometry, and fluorescence microscopy.
Journal ArticleDOI
The Colour Index
TL;DR: The Colour Index as discussed by the authors is an international compilation of the structure and properties of dyes and pigments, as well as a system of numbering these materials, which is a potentially valuable tool for all users of colorants.
