① Pure cotton flannel has hygroscopicity: pure cotton flannel has good hygroscopicity. Under normal circumstances, the fiber can absorb water into the surrounding atmosphere, with a moisture content of 8-10%, so it contacts people’s skin and makes people feel soft but not stiff. If the humidity of cotton cloth increases and the surrounding temperature is high, all the water content in the fiber will evaporate and disperse, so as to keep the fabric in water balance and make people feel comfortable.
② Pure cotton flannel has moisture retention: because flannel is a bad conductor of heat and electricity, the thermal conductivity is very low, and because cotton fiber itself has the advantages of porosity and high elasticity, a large amount of air can be accumulated between fibers, and air is a bad conductor of heat and electricity, pure cotton fiber textiles have good moisture retention, and people feel warm wearing pure cotton fabrics and clothes.
③ Pure cotton flannel has heat resistance: pure cotton flannel has good heat resistance. When the temperature is below 110 ℃, it will only cause moisture evaporation on the fabric and will not damage the fiber. Therefore, the wearing, washing, printing and dyeing of pure cotton fabric at room temperature have no impact on the fabric, which improves the washing and wearing performance of pure cotton fabric.
④ Pure cotton flannel has alkali resistance: cotton fiber has great resistance to alkali. When cotton fiber is in alkali solution, the fiber will not be damaged. This performance is conducive to washing, disinfection and impurity removal after taking. At the same time, it can also dye, print and process pure cotton textiles, so as to produce more new cotton varieties.
⑤ Pure cotton flannel is hygienic: cotton fiber is a natural fiber, its main component is cellulose, and a small amount of waxy substances, nitrogen-containing substances and pectin. The pure cotton fabric has been inspected and practiced in many aspects. The contact between the fabric and the skin has no stimulation and negative effect. It is beneficial and harmless to the human body for a long time, and has good hygienic performance.
Flannel (flano, flannel) is a foreign word. It is a soft and suede wool fabric made of combed wool yarn. It was created in Wales, England in the 18th century. In China, it generally refers to the woolen fabric with jacquard style woven from mixed color combed wool yarn. Its surface is covered with a layer of plump, fine and clean wool, does not expose the texture, feels soft and flat, and its body bone is slightly thinner than Melden.
