On the recovery of fibres by tape lifts, tape scanning, and manual isolation

The effect of tape type, taping method and tape storage temperature on the retrieval rate of fibres from various surfaces: An example of data generation and analysis to facilitate trace evidence recovery validation and optimisation

“…Figure 6 summarises those findings and provides evidence that the overall median target fibre retrieval rate from the smooth polyester tracksuit trousers exceeded those for each of all the other textile surfaces except the seatbelt and the smooth cotton T-shirt. The finding of the latter of these two exceptions (a surface not studied by Lowrie & Jackson [2938]) is essentially consistent with the findings of Schotman & vVan dDer Weerd [9], as, in their study there was some overlap between the retrieval rates of polyester target fibres on cotton fabric and of such target fibres on polyester fabric. Although, in their study with polyester target fibres, cotton fabric produced, on average (x̅ = 97.4%, n = 3), higher retrieval rates than did polyester fabric (x̅ = 96.0%, n = 3).…”

“…There is only one study reported in which the fibre retrieval properties of J-LAR were investigated [9]. This concerned its use with garments, not other surface types.…”

Readers interested in comparing the performance of a wider range of tape types are referred to the work of Schotman & vVan der Weerd [9], and Wael, Gason & Baes [5]. Similarly, the work that Warwickshire and West Mercia Police wished to see strongly influenced the choice of the other experimental factor variables and their levels used.…”
