The reason why the towel has been hardened for a long time is summarized as:
The towel frequently contacts the sweat glands on the skin during use, and the pores continuously secrete body fluids such as oil and sweat. Impurities such as oils, proteins, dander, inorganic salts, and gray scale are not easily dissolved in water. If it is washed with pure water, it is difficult to clean it, and these impurities will accumulate in the towel fiber. In addition, the soap used in bathing and washing the face is easily combined with calcium and magnesium ions in the water to form calcium and magnesium soap, which penetrates into the fibers along the grease, so that the towel loop fibers are hard and rough. Therefore, the longer the use time, the more grease and impurities accumulated between the fibers, the more the towel feels harder.
