Approaches to research and their application

We may be interested in determining whether the type of fiber or the type of fabric structure dominates the tendency for a next-to-skin fabric to retain body odor. The experiment needs to be designed. Perhaps there is more than one experiment, and the various experiments need to be considered together. Indeed, McQueen s questions involved several types of investigation—human sensory perception (McQueen et al., 2(X)7a), instrumental determination of volatiles (McQueen et al., 2008), and links between odor volatiles and microorganisms resident on the human skin (McQueen et al., 2007b). 

Having demonstrated that odor of high intensity emanated from polyester fabrics and that this continued to emanate from polyester fabrics even after 28 days, McQueen sought to detect possible compounds in the headspace above the wool, cotton, and polyester fabrics using the instrumental technique of proton-transfer-reaction spectrometry (McQueen et al., 2008). Malodors continued to increase over 7 days with the polyester fabrics, but not with either the wool or the cotton fabrics, with the intensity of axillary odor seemingly inversely related to fiber hygroscopicity.
