Towel used for a long time, become stiff people uncomfortable, the most important is contaminated by a large number of bacteria, harmful to human body. The towel made of pure cotton yarn, cotton fiber is a tubular structure, the cell containing the hollow cavity, can store water; its main chemical composition of cellulose molecule contains a large number of hydrophilic genes, can absorb water. The moisture absorption and water storage property of the cotton yarn makes the towels feel comfortable and the cleaning ability is strong, and is suitable for cleaning. But it is also because of this characteristic that it provides a convenient condition for the growth of bacteria. Bacteria love warm and humid environments best. A long time in the wet towel, after a certain period of time, has become a paradise for bacteria, combined with human skin oil, dust and impurities in the water, the bacteria in the air and deposited on the towel, then towel wipe the skin, not only plays the role of clean, but will stain the skin, clogging pores. Women who like make-up and children with fast metabolism have more oil and more infections, which is especially harmful.
In the recently held annual meeting of the textile association, according to home textile experts, personal towels should be replaced about 30 days, the maximum should not exceed 40 days.
We usually use water, there are some minerals that can be dissolved by water, such as calcium, magnesium and so on. One of the soaps we use is a substance called fatty acid sodium. Sodium salt, which meets calcium and magnesium in water, can become a deposit that can not be dissolved by water. These deposits stay in the fibers of the towels and harden the towels. When the hard towels are boiled in lye or vinegar, the deposits are removed and the towels are softened again.
