Popular Science On Cotton Fabrics

- Jul 18, 2020-

Go to the mall to buy clothes or towels for daily necessities. Shopping guides will tell us to choose pure cotton. Over time, the clothes, towels, bed sheets, socks and other products closely related to our lives at home have become synonymous with "pure cotton". So is cotton fabric really that good?


Regarding what is good about pure cotton fabrics, Nuoanfen's designers mainly explained in terms of moisture absorption, heat preservation, heat resistance, alkali resistance, and hygiene:


Hygroscopicity: Cotton fiber has good hygroscopicity. Under normal conditions, cotton fiber can absorb moisture from the surrounding atmosphere, and its moisture content is 8-10%, so it touches human skin and makes people feel soft and soft. Not stiff. If the humidity of the cotton cloth increases and the surrounding temperature is higher, all the moisture contained in the fiber will evaporate, so that the fabric can maintain a water balance and make people feel comfortable.


Heat preservation: Because cotton fiber is a poor conductor of heat and electricity, the thermal conductivity is extremely low, and because cotton fiber itself has the advantages of porosity and high elasticity, a large amount of air can accumulate between the fibers, and air is a poor conductor of heat and electricity. Therefore, pure cotton fiber textiles have good thermal insulation properties, and people feel warm when wearing pure cotton clothing.


Heat resistance: Pure cotton fabric has good heat resistance. When it is below 110℃, it will only cause the moisture on the fabric to evaporate without damaging the fiber. Therefore, the pure cotton fabric will have no effect on the fabric when it is worn and used at room temperature. This pair improves the washability and wearability of pure cotton fabrics.


Alkali resistance: The cotton fiber has a high resistance to alkali. 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 it can also be used for pure cotton textiles. Dyeing, printing and various processing techniques to produce more new varieties of cotton.


Hygiene: Cotton fiber is a natural fiber, its main component is cellulose, containing a small amount of waxy substances, nitrogenous substances and pectin. The pure cotton fabric has been tested and practiced in many ways, and the fabric has no irritation or side effects in contact with the skin. It is beneficial and harmless to the human body when worn for a long time, and has good hygiene properties.


Of course, everything has two sides, and pure cotton fabrics also have some disadvantages, such as:


Wrinkles are more difficult to smooth; easy to shrink, the shrinkage rate of pure cotton clothing is 2% to 5%; afraid of acid, when acid (such as vinegar) accidentally gets on the clothes, they should be washed in time to prevent acetic acid from damaging the clothes .
