“…The effects of fabric contacting a heating plate and open flame showed that characteristic changes occur in different types of fabric and fibers (Was-Gubala & Kraub, 2006). This is not entirely a novel approach.…”

Forensic science has long been used in criminal investigations and the justice system. The standards applied to contemporary forensic practice have changed dramatically in the past decade. Presented here is a modern-day review of textile damage science in the context of these changing standards, and how they have challenged the presentation of scientific evidence. The prevalence of textile damage examinations is fluctuating in the current forensic environment. Some laboratories are conducting more examinations than ever, and other laboratories are no longer able to conduct examinations due to limitations in resourcing or case numbers. This dynamic landscape will no doubt continue as the occurrence of crime fluctuates throughout and beyond the pandemic affecting the world.

“…The heat not only causes irreversible changes in the morphological and chemical structure of the fibre but is often the cause of its total destruction. The task of the forensic expert examining thermally altered fibres is to define the properties of the textile material before the changes that occurred under the influence of heat [15]. Many modern instrumental analysis methods allow fibres altered in such a way to be examined to some extent.…”

The detection of changes in the morphological and chemical structure of four cotton/polyester blend fabrics and their constituent fibres caused by thermal radiation was the purpose of the study. Relatively short exposure times, i.e., 20 s, 25 s, 30 s and 40 s, of fabrics for an incident heat flux density of 10 kW/m2 were applied so that they did not cause changes visible to the naked eye. Such experimental conditions have been selected to resemble the ones that may occur during firefighting, rescue operations, some professional activities as well as during criminal events. The assumption that using the sequence of physicochemical methods, i.e., optical microscopy, scanning electron microscopy and FTIR spectroscopy, will make it possible to identify selected thermal changes in examined materials caused by a short-term temperature increase has been positively verified. Out of applied techniques, scanning electron microscopy showed the highest efficiency in tracking morphological changes in fibres occurring under the influence of heat radiation, while the FTIR method allows for the identification of thermal changes in the chemical structure of cotton fibres. Optical microscopic methods were also characterised by relatively high usefulness in the detection of thermal changes, especially in terms of the physical microstructure of PES fibres. The changes occurring in the fibres due to the action of heat radiation depend not only on the thermal behaviour of a particular type of fibre but also on the structural parameters of the examined textiles, i.e., porosity, and the mutual position of particular types of fibres in the three-dimensional structure of yarns and fabrics. Moreover, the studies revealed the presence of tiny, deformed balls at the ends of the thermoplastic fibres, visible on the surface of some original polyester-cotton textiles, caused by a singeing technological process, which should be taken into account during interpretation of analytical findings.
