You’re Probably Drying Your Towels Wrong - And It’s Ruining Them Faster

They are not often given much consideration. Yet they're one of the most durable items found in any household. Every day they take in water, undergo wash cycles and are subject to severe drying conditions. When they begin to become hard, brittle, or thin much faster than they expected, people blame the detergent or the water quality. However, the real problem usually lies with how the dried products are dried.

The Hidden Science Behind Towel Wear

In a small scale they are less delicate than they seem. They are mostly made of cotton, with a looped structure that is designed to hold moisture effectively. Loops in towels give them absorption and softness, however they also are susceptible to deterioration when subjected to extremely dry conditions.


A groundbreaking study, presented at the American Chemical Society by researcher Agnes Buisson at Universite de Haute Alsace in France showed just how destructive the heat of high temperatures can be. Fabrics of cotton that were drying in machines at temperatures of around 150°F broke 25 percent more easily when compared to those that were dried with gentler techniques like dry air and drip drying.

Research has shown that extreme temperature causes thermal degradation as well as hydrolysis, which breaks down fibers of cellulose at the molecular scale and leading to micro-sized cracks. Cracks in the structure weaken and cause the accumulation of excessive lint and reduced flexibility, and even faster wear.

To add to this, an experiment study that was published within the African Journal of Applied Research by Patience Danquah M. Gavor, and D. Agyirifo at the University of Cape Coast in Ghana studied how various drying techniques affect bath towels. Their research went beyond durability, revealing that vigorous drying does not only weaken the fibers, but also caused an increase in fungal and bacterial contamination. Fibers that were damaged created tiny pockets where the residues of moisture may remain and encourage the growth of microbial.

Everyday Habits That Are Damaging Your Towels

Unintentionally, many common dry habits decrease the longevity of towels. Tumble drying with high temperatures is one of the main culprits. Although it might seem efficacious, it saps the natural oils out of cotton fibers which causes brittleness and shrinkage. In time, the repeated strain can diminish the absorbency and softness of towels drastically.

Sun drying, which is often thought of as an option that is natural, however it has its drawbacks. The research that was published in International Journal of Clothing Science and Technology in the United Kingdom found that line drying under direct sun can cause fabrics to feel stiff and similar to cardboard. UV rays damage fibres and can fade dyes and the absence of tumbling causes the loops to form clumps which reduces their softness.

Overdrying can be another issue that is often overlooked. Drying towels longer than they are required may appear innocent, however it increases the stress on fibers. The reports on damage from dryers show the effects of prolonged exposure to heat on fabric, particularly at the points of stress like hems and edges.

The findings from research on hygiene add to these issues. A study of research conducted by Patrick and co-workers at the West Midlands Public Health Laboratory located in the United Kingdom, published through the National Institutes of Health database revealed that methods of drying have a significant impact on moisture retention. Although the study was is focused on hand drying this principle is applicable to all types of drying. Drying improperly or insufficiently results in residual moisture that could compromise cleanliness as well as the integrity of fabric.

When Drying Becomes a Hygiene Problem

Drying towels is also a factor in hygiene that the majority of people aren't aware. Dry fibers provide a perfect conditions for the growth of fungi and bacteria. Researchers from the University of Cape Coast study discovered that towels not properly dried were significantly more prone to microbes.

Additional evidence is provided by an article that was published in Nature Scientific Reports by researchers from Iran. The study looked at different hand-drying techniques and concluded that insufficient drying may leave surfaces less clean. If applied to towels for bathing the study suggests that bad drying techniques not only harm the fabric, but may also render towels less hygiene-friendly over long periods of.

When the environment is humid in bathrooms for instance, in which towels hang with no adequate airflow, the issue gets more severe. The towel that isn't fully drys isn't just uncomfortable to wash, it can be a source of undesirable microbes.

Smarter Drying for Longer-Lasting Towels

To preserve towels, it doesn't need complex procedures, however it requires a change to a different method of. Reduced heat exposure is among of the most efficient steps. The shorter drying times and air drying may effectively reduce damage to fibers. A study by the American Chemical Society study showed that cutting drying times by as little as 10 to 20 percent could prevent a lot of the structural degeneration.

Drying in the air is beneficial provided it is done properly. Drying towels inside or outside in shaded areas can help to protect the skin from UV damage, while preserving the softness. Simply shaking towels prior to hanging could separate fibers and reduce stiffness.

The quality of the material also plays a factor. The towels that have greater GSM and especially ones comprised of Egyptian and Turkish cotton, are likely to last longer. Yet, even the most durable towels can degrade quickly if exposed to extreme drying conditions.

Rethinking a Simple Routine

Drying the towels could seem to be an easy, everyday task however the consequences are quite significant. Research conducted by scientists from France, Ghana, the United Kingdom, and Iran repeatedly shows that poor drying damages fibers, diminishes the softness of towels, and can even impact hygiene. A seemingly simple route today could actually shorten the longevity of your towels for years.

When you alter your drying routine and putting them through some extra attention, you can be able to preserve their softness absorption, and hygiene to last for a long time. At the end of the day, the distinction between a soft lasting, long-lasting towel and damaged, scratchy one usually is in the method of drying.
