Abstract
The study of textiles damage is an immensely valuable resource in the criminal examination that is used to find a way to resolve the stabbing cases, shooting cases and rape allegations. It also can overcome arson threats and "acid assaults." Here, the literature is reviewed to examine work on blunt force impact, stabbing and slashing wounds, the occurrence of proof forgery in sexual attacks, projectile harm, and the effect of decomposition on textile damage, amongst many others. It is evident there is a shortage of work in the field, but when the study was done, it was insightful and meaningful. Nevertheless, there are fields where more research is required, such as a thorough analysis of usual wear and tear, and ability of additives to inflict harm to textiles. This research deals with blood pattern analysis on 6 different fabrics that are most common in Pakistan. Almost 8 patterns were applied on these 6 fabrics to analyze bloodstain radius, diameter, width, height, length, angle of impact and area. These all parameters were studied on both laundry and brand new fabric to analyze differences in results. It was observed that bloodstains cover most of area on laundry fabric as compared to brand new fabric. Blood drop sizes were also observed that was different according to height. Absorbance factor of fabrics were also checked and it was observed that net had high absorbance factor.
