Hygroscopicity: Cotton fibers have good hygroscopicity. Under normal conditions, the fiber absorbs moisture into the surrounding atmosphere, and its moisture content is 8-10%, so it contacts human skin and makes people feel soft and not stiff. If the humidity of the cotton product increases and the ambient temperature is high, the water content in the fiber will all evaporate and dissipate, so that the cotton product maintains the water balance state, which makes people feel comfortable.
Moisture retention: Since cotton fiber is a poor conductor of heat and electricity, the heat transfer coefficient is extremely low, and because the cotton fiber itself has porosity and high elasticity, a large amount of air can be accumulated between the fibers, and the air is a poor conductor of heat and electricity. Therefore, pure cotton fiber products have good moisturizing properties, and the use of pure cotton products makes people feel warm.
Heat resistance: The heat resistance of pure cotton products is good. When the temperature is below 110 °C, it will only cause the water on the fabric to evaporate without damaging the fibers. Therefore, the pure cotton products are used at normal temperature, and the washing and dyeing have no effect on the products. This improves the durability of the cotton product.
Alkali resistance: cotton fiber has greater resistance to alkali. Cotton fiber does not break in alkali solution. This property is good for washing and disinfecting impurities after washing. It can also be used for pure cotton products. Dyeing, printing and various processing to produce more new varieties of cotton.
Hygiene: Cotton fiber is a natural fiber, its main component is cellulose, and a small amount of waxy substances and nitrogen and pectin. Pure cotton products have been checked and practiced in many aspects. No contact with the skin, no side effects, long-term use is beneficial to the human body, and the hygienic performance is good.
