Chapter 6. Conclusions and Future Work

6.4 Future Works

Once improved with the suggestions previously mentioned, the overall method could be utilized for other areas in the textile field, and possibly beyond. The next area of assessment could be apparel testing. One would need to reconfigure the methods to target the appropriate odor compounds responsible for axillary odor, but the rest could be conducted in the same manner to affiliate odor scores with the sampled concentrations.

The potential for conducting sampling with a miniature chemical agent monitoring device (Mini-CAM) is possible as well. Once the method was established for targeted compounds, one could potentially improve the speed of the air sampling process. The Mini-CAM is capable of providing real-time results for the concentrations present in the sampled product at any given time. The real-time feature may provide the ability to see at which rate the odor compounds dissipate from the shoes, giving an idea as to how much odor is lost with lack of replenishment over time.

Another route to consider for future works is the use of sweating manikins in conjunction with the air sampling and GC-FID methods. One could incubate a shoe, sock, or piece of apparel with odor-causing bacteria during a one-time human-based wear of the product. As long as the bacteria were kept in optimal conditions for odor production, which should be more easily controlled with a manikin in an environmentally-controlled chamber, one could potentially produce weeks’ worth of data for a wear trial population in a shorter period of time. Once odor scores were established by a significantly large population, the concentrations found from sampling the product on the manikin could be correlated to the scores, providing the line of best fit equation needed for future predictions.

Future testing of products should also consider the effect of size and materials used by results from this correlation method. The wear trial involved mainly the use of a size 9 shoe. Seeing as how structure appears to play a significant role, it is reasonable to think that size of a product is just as important in the overall scope of perceived odor. Granted this is one more variable to worry about during testing, but it may be feasible to accomplish with the established methods above.
