What are the characteristics of general cotton flannel:
① Pure cotton flannel has hygroscopicity: pure cotton flannel has good hygroscopicity. Under normal conditions, the fiber can absorb moisture from the surrounding atmosphere, and its moisture content is 8-10%, so it touches Human skin makes people feel soft and not stiff. If the humidity of the cotton cloth increases and the surrounding temperature is higher, all the water contained in the fiber will evaporate and disperse, so that the fabric can maintain a water balance and make people feel comfortable.
② Pure cotton flannel has moisture retention: because the flannel is a poor conductor of heat and electricity, the thermal conductivity is extremely low, and because the cotton fiber itself has the advantages of porosity and high elasticity, a large amount of air can accumulate between the fibers. It is a poor conductor of heat and electricity. Therefore, pure cotton fiber textiles have good moisture retention. Wearing pure cotton clothing makes people feel warm.
③ Pure cotton flannel has heat resistance: pure cotton flannel has good heat resistance. When the temperature is below 110 ℃, it will only cause the moisture on the fabric to evaporate without damaging the fiber. Therefore, the pure cotton fabric is worn and used at room temperature. Washing, printing and dyeing, etc. have no effect on the fabrics, thus improving the washability and durability of cotton fabrics.
④ Pure cotton flannel has alkali resistance: cotton fiber has greater resistance to alkali, and the cotton fiber will not be damaged in the alkali solution. This performance is conducive to the washing of pollution after consumption, disinfection and removal of impurities, and at the same time, It is also possible to dye, print and process all kinds of pure cotton textiles to produce more new varieties of cotton weaving.
⑤ Pure cotton flannel is hygienic: cotton fiber is a natural fiber, its main component is cellulose, and a small number of waxy substances, nitrogenous substances and pectin. Pure cotton fabric has been tested and practiced in many ways, and the fabric has no irritation or negative effect in contact with the skin. It is beneficial and harmless to the human body when worn for a long time, and has good hygienic properties.
