Some differences between the two fabrics were noted, therefore fabric structure and properties must be considered when conducting BPA on apparel fabrics. Statistically, drop height did not affect the size of the parent bloodstain (wet or dry), but did affect the number of satellite bloodstains formed. Very little blood was transferred between a bloody fabric and a second piece of fabric. The blood soaked unequally through to the technical rear of both fabrics. Visually, the passive bloodstain patterns produced on the technical face of fabrics from the different drop heights were similar. The effect of drop height on the development of passive, absorbed and transferred bloodstains was investigated using image analysis and statistical tools. High-speed video was used to investigate the interaction of the blood and fabric at impact. In this work, the development of bloodstains (passive, absorbed and transferred) dropped from three different heights (500, 1,000, 1,500 mm) on two cotton apparel fabrics (1 × 1 rib knit, drill) was investigated. However, the interaction of blood and apparel fabrics has not been widely studied. Bloodstain pattern analysis (BPA) is the investigation and interpretation of blood deposited at crime scenes.
