Hygroscopic properties of pure cotton children's sweater: cotton fiber has good hygroscopic properties. Under normal conditions, the fiber absorbs moisture into the surrounding air, which is 8-10% moisture, so it touches the human skin, making it feel soft rather than stiff. If the humidity of the cotton cloth increases and the surrounding temperature rises, all the water in the fiber will evaporate and disperse, leaving the fabric in a state of water balance and comfortable feeling.
Thermal insulation of pure cotton children's sweater: because cotton fiber is a bad conductor, the thermal conductivity is very low, and because the cotton fiber itself has the advantages of porous and high elasticity, there will be a lot of air accumulated between the fibers, and the air is a bad conductor of heat and electricity, therefore, pure cotton fiber textiles have good thermal insulation, people will feel warm when wearing pure cotton clothes.
Heat resistance of pure cotton children's sweater: Pure cotton fabric has good heat resistance. When the temperature is below 110 degrees Celsius, it will only cause the moisture on the fabric to evaporate, without damaging the fiber. Therefore, cotton fabric at room temperature has no effect on the fabric, such as wearing, washing, printing and dyeing. Thus improve the washability and durability of pure cotton fabric.
Cotton children's sweater alkali resistance: cotton fiber alkali resistance. In an alkaline solution, cotton fibers are not damaged. This feature facilitates washing contamination, disinfection and removal of impurities after use. Meanwhile, pure cotton textiles can also be dyed, printed and processed by various processes to produce more new varieties of cotton.
Health of pure cotton children's sweater: cotton fiber is a natural fiber, its main component is cellulose, containing a small amount of wax, nitrogen and pectin. After testing and practice in many aspects, pure cotton fabric has no irritation and side effects in contact with skin, which is beneficial to human body and has good health performance for long-term wear.
