“…Next, the cotton fibers are treated with a cellulase solution to break the covalent bonds between dyes and fibers. Once the enzymatic treatment is done, the reactive dyes are commonly bonded to a cellobiose unit that can be analyzed by chromatography and MS [18,21,22].…”

Dyes have become common substances since they are employed in mostly all objects surrounding our daily activities such as clothing and upholstery. Based on the usage and disposal of these objects, the transfer of the dyes to other media such as soil and water increases their prevalence in our environment. However, this prevalence could help to solve crimes and pollution problems if detection techniques are proper. For that reason, the detection and characterization of dyes in complex matrices is important to determine the possible events leading to their deposition (natural degradation, attempts of removal, possible match with evidence, among others).Currently, there are several chromatographic and mass spectrometric approaches used for the identification of these organic molecules and their derivatives with high specificity and accuracy. This review presents current chromatographic and mass spectrometric methods that are used for the detection and characterization of disperse, acid, basic, and reactive dyes, and their derivatives.

“…However, numerous solvent mixture systems have been documented for this purpose . Studies of dye extraction and TLC have been published for dyes on cotton, wool, and various other synthetic fibers . TLC is able to identify the extracted dyes and dye mixtures, but most of the textile fibers contain complex dye patterns.…”

Polymeric fibers are one kind of trace evidence found in the crime scenes, and they play a crucial role in criminal investigation. Identification and comparison of polymeric fibers are a direct result of professional analysis. When performed properly, the analytical method used in differentiating fibers of different origins can be of high evidential value. Regular forensic examinations of synthetic fibers to determine type and subtype are based on microscopy, spectroscopy, chromatographic, and mass spectrometry. This review covers different analytical methods used in the forensic analysis and comparison of synthetic fibers.

“…The extraction of fiber dyes for analysis by HPLC has been described (566). Enzymatic digestion of cotton fibers dyed with reactive dyes produces colored solutions which can be analyzed by TLC (567). A method for extracting reactive dyes for TLC analysis from wool fibers has been reported (568).…”

Cellulase digestion of cotton dyed with reactive dyes and analysis of the products by thin layer chromatography

Abstract: Enzymatic digestion of cotton fibres dyed with reactive dyes produces coloured solutions. These are not true dye extracts but they are nonetheless amenable to separation and analysis by thin layer chromatography.
