Cotton has good hygroscopicity. Under normal conditions, the fiber can absorb water into the surrounding atmosphere, and its water content is 8-10%, so it contacts human skin and makes people feel soft and 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 and down keep warm, chemical fiber porous fiber has better hole-to-hole warming effect, and silk is cooler for summer use;
The cotton fabric has good heat resistance. When the temperature is below 110 °C, only the baby sleeping bag will 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. This improves the wear resistance of the cotton fabric.
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.
