1. strong Hygroscopicity, shrinkage is large, approximately 4~10%
2. alkaline not acid-proof. Cotton on mineral acids are unstable, even dilute sulfuric acid will cause it to be destroyed, but weak organic acids, hardly destructive. Cotton more alkalis, dilute alkalis at room temperature on cotton will not take effect, but under the action of strong base, cotton strength is reduced. Used 20% liquid caustic soda processing cotton, can be "silky" cotton.
3. the light resistance, heat resistance. Sunshine and cotton will be slow to be oxidized in the atmosphere, makes a strong decline. Prolonged high temperatures cause damage to cotton, but their tolerance to 125~150℃ short high-temperature treatment.
4. microbes have a destructive effect on cotton fabric, in that it is not mildew.
5. health: cotton is a natural fiber, its main ingredient is cellulose, there is a small amount of wax-like substance and nitrogen-containing substances and pectin. Multiple examinations by cotton fabric, and practice, without any contact with the skin to stimulate the fabric without side effects, beneficial to the human body, health and good performance.
