Advantages of 100% cotton towels： 1. moisture absorption, shrinkage larger, about 4~10% 2., alkali resistant, non acid. Cotton is very unstable to inorganic acids. Even dilute sulfuric acid can destroy them. But the action of organic acids is weak and almost no damage. Cotton is more alkaline, generally dilute alkali at room temperature on cotton does not play a role, but the strong alkali action, cotton strength will decline. Often use 20% caustic soda liquid to deal with cotton cloth, can get "mercerized" cotton cloth. 3. light resistance, heat resistance in general. In sunlight and the atmosphere, cotton fibers are slowly oxidized and reduced in strength. Long term high temperature can damage the cotton fabric, but it is short of 125~150 DEG C and high temperature treatment. 4. microorganisms are destructive to cotton fabrics and are resistant to mildew. 5. hygiene: cotton fiber is a natural fiber, the main component is cellulose, there are a small amount of waxy substances and nitrogen containing substances and pectin. Pure cotton fabric has been examined and implemented in many ways, and the fabric has no irritation to the skin. It has no negative effect. It is beneficial and harmless to the human body for a long time, and it has good hygienic performance.
