Cotton fabric has good hygroscopicity when used. Under normal conditions, its fiber can absorb water into the surrounding atmosphere. Its moisture content is 8-10%, so it contacts human skin and makes people feel soft. Not stiff. If the humidity of the cotton cloth increases and the ambient temperature is high, the water content in the fiber will all evaporate and disperse, so that the fabric maintains a water balance state, which makes people feel comfortable.
Cotton fabric is a poor conductor of heat and electricity. Its heat transfer coefficient is extremely low during operation. Because of its porous nature and high elasticity, cotton fiber can accumulate a large amount of air between the fibers, and the air is hot and electric. The poor conductor, therefore, cotton fiber textiles have good warmth, wearing cotton fabric clothing makes people feel warm.
The heat resistance of the cotton fabric is good. When the temperature is below 110 °C, it will only cause the water on the fabric to evaporate without damaging the fiber. Therefore, the cotton fabric is worn at normal temperature, and the washing and dyeing have no effect on the fabric. It improves the washability and durability of cotton fabrics.
Cotton fiber has great resistance to alkali. The cotton fiber does not break in the alkali solution. This property is beneficial to the washing and disinfection of impurities after washing, and can also dye and print pure cotton textiles. Various processes are processed to produce more new varieties of cotton.
