Today, let’s talk to you about the characteristics of cotton fabrics. What are their advantages and disadvantages?
Advantages of pure cotton fabrics:
1. Hygroscopicity:
Cotton fiber has good hygroscopicity. The fiber can absorb moisture from the surrounding atmosphere, and its moisture content is 8-10%, so when it contacts people’s skin, it 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:
Because cotton fiber is a poor conductor of heat and electricity, the thermal conductivity coefficient is extremely low, and because cotton fiber itself has the advantages of porosity and high elasticity, the fiber A large amount of air can accumulate in the space, and air is a poor conductor of heat and electricity. Therefore, pure cotton fiber textiles have good thermal insulation properties, and wearing pure cotton fabric clothing makes people feel warm.
3. Heat resistance:
Pure cotton fabric has good heat resistance. When it is below 110℃, it will only cause the water on the fabric to evaporate without damaging the fiber. Therefore, pure cotton The fabric has no effect on the fabric when worn, used, washed, printed and dyed at room temperature, thus improving the washability and durability of pure cotton fabrics.
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 and disinfection of contamination after consumption. Impurities can be removed, and pure cotton textiles can also be dyed, printed and processed in various processes to produce more new varieties of cotton fabrics.
5. Hygiene:
Cotton fiber is a natural fiber, its main component is cellulose, and contains a small amount of waxy substances, nitrogen-containing 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 of pure cotton fabrics:
1. It wrinkles easily, and it is difficult to smooth out wrinkles.
2. It shrinks easily. The shrinkage rate of pure cotton clothing is 2% to 5%. Exceptions are made after special processing or washing.
3. Easy to deform and lack of 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 completely remove.
5. Acid resistance, especially acid-resistant. When concentrated sulfuric acid contaminates cotton, the cotton will be Burning holes, when acid (such as vinegar) accidentally gets on the clothes, it should be cleaned in time to prevent acetic acid from causing fatal damage to the clothes.
