Have you ever wondered why a polyester T-shirt tends to be smellier than a cotton one after a workout? According to recent research conducted at the University of Alberta, the answer lies in the unique properties of different types of fibers. The analysis of various fibers soaked in a simulated sweat solution revealed that cellulosic fibers like cotton and viscose tend to absorb and release smaller amounts of odor-causing compounds compared to synthetic fibers such as polyester, nylon, and wool.

The study, led by Rachel McQueen, a clothing and textiles scientist, sheds light on why some fabrics retain odors more than others. The research, published in the Textile Research Journal, highlights the importance of understanding how odorants transfer and are selectively absorbed by different fiber types when exposed to sweat. By using a simulated liquid sweat solution, the study provided a more realistic approach to investigating odor retention in textiles, as opposed to standard methods that solely focus on airborne odor transfer.

Sweat, primarily composed of water with oily compounds, plays a crucial role in generating body odors when bacteria break down these compounds. The interaction between these oily compounds and odorants in sweat varies depending on the fiber chemistry of the fabric. While cellulosic fibers like cotton and viscose have a higher affinity for water and absorb more moisture from sweat, synthetic fibers like polyester repel water and tend to absorb more odorants and oily compounds, leading to persistent odor retention.

The findings of the study have significant implications for consumers when selecting clothing items. The research suggests that garments made from cellulosic fibers are less prone to developing odors compared to those made from synthetic fibers. While nylon and wool initially absorb a considerable amount of odorants, they also dissipate them more quickly than polyester. This indicates that airing out nylon and wool garments may be sufficient to remove odors, reducing the need for frequent washing.

In light of the study’s results, consumers are encouraged to consider the fiber composition of clothing items to make more informed choices. Opting for cellulosic fibers like cotton and viscose over synthetic fibers like polyester can help prevent persistent odors. Additionally, the study cautions against relying solely on anti-odor claims on clothing labels, as these properties may not be as effective in combating odor retention related to fiber chemistry interactions.

The research findings also have implications for textile scientists and manufacturers in developing fabrics with improved odor-resistant properties. By understanding the key role of fiber chemistry in odor retention, advancements in fabric technology may lead to the creation of synthetic fibers that are more water-loving and less inclined to retain oily compounds, ultimately offering consumers more odor-free clothing options.
