Why did the towel break?

Towels have been stained after contact with the body. Dirty towels will start to breed microorganisms in a humid environment, and towels with microorganisms will be corroded. Just like soaking a towel in sewage, cotton fibers will soon rot. The towel just rotted away.

Most holes in towels are irregular. Observing the fragile discolored parts with a microscope, it was found that there was obvious mildew on the surface of the fiber, and the colony of fibrous mold could still be detected after washing. Fragile towels are stored in hot and humid containers after washing or wiping sweat and before drying. The longer they are stored, the easier they become brittle.

There are also new towels that break when washed. These towels are pulp towels that have not been washed and desized, and the starch inside is the nutrient of mold. Once it encounters humid and sultry environmental conditions, mold will multiply rapidly and secrete enzymes to decompose fiber and starch into glucose.

At the same time, the dander contained in sweat (including protein, fat, amino acids and inorganic salts such as potassium and sodium) further promotes the reproduction of microorganisms such as bacteria and releases acidic substances, which is not only beneficial to the survival of bacteria, but also accelerates the hydrolysis of starch and fiber. Therefore, the new towel will be moldy and brittle in a hot and humid environment without washing starch slurry.
