What are the advantages of pure cotton fabrics?
1. Hygroscopicity: Cotton fiber has good hygroscopicity. Under normal circumstances, the fiber can absorb moisture from the surrounding atmosphere, and its moisture content is 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 moisture contained in the fiber will evaporate and dissipate, keeping the fabric in a water balance state and making people feel comfortable.
2. Insulation: Since cotton fiber is a poor conductor of heat and electricity, the thermal conductivity Extremely low, and because the cotton fiber itself is porous and has 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 are suitable for wearing pure cotton clothing. Make people feel warm.
3. Heat resistance: Pure cotton fabric has good heat resistance. When it is below 110℃, it will only cause moisture on the fabric. Evaporation will not damage the fiber, so the pure cotton fabric has no effect on the fabric when worn, used, washed, printed and dyed at room temperature, thus improving the washing and wearing resistance of the pure cotton fabric. , 4. Alkali resistance: Cotton fiber has greater resistance to alkali. In the alkali solution, the fiber will not be damaged. This property is conducive to the washing of pollution after consumption, disinfection and removal of impurities, and can also be used to clean pure products. Cotton textiles are dyed, printed and processed in various processes to produce more new varieties of cotton fabrics.
5. Hygiene: Cotton fiber is a natural fiber, and its main component is cellulose. Contains a small amount of waxy substances, nitrogenous substances and pectin. Pure cotton fabrics have been tested and practiced in many aspects. There is no irritation or side effects when the fabric comes into contact with the skin. It is beneficial to the human body when worn for a long time and has good hygienic performance.
Disadvantages: 1. It wrinkles easily, and it is difficult to smooth out wrinkles. 2. It is easy to shrink. The shrinkage rate of pure cotton clothing is 2% to 5%, except for special processing or washing. 3. Easily deformed and lacks elasticity. Pure cotton clothes will be easily deformed, especially summer clothes because the fabric is relatively thin. 4. It is easy to stick to hair and difficult to remove completely. 5. Acid resistance, especially acid-phobic. When concentrated sulfuric acid contaminates cotton, holes will be burned into the cotton. When acid (such as vinegar) accidentally gets on the clothes, you should remove it immediately.
Wash to prevent acetic acid from causing fatal damage to clothes.
