Cotton belt refers to a fabric woven from cotton yarn or cotton and cotton-type chemical fiber blended yarn. The cotton cotton belt is woven from pure cotton yarn, and the cotton belt has a wide variety of colors and colors. It can be divided into primary color cotton cloth, dyed cotton cloth, printed cotton cloth and yarn-dyed cotton cloth according to the dyeing method; or it can be divided into plain cotton belt, twill cotton belt and forged cotton belt according to the cotton belt structure. The cotton belt which is blended and interwoven by cotton and other fibers is collectively referred to as cotton blended and interwoven cotton belt. This includes the combination of cotton and other natural fibers, as well as the combination of cotton and various chemical fibers. Usually, cotton and chemical fiber are combined into various varieties and practical fabrics with various advantages.
Cotton belt characteristics
         It has the following characteristics:
         1. The cotton belt has strong hygroscopicity and a large shrinkage rate of about 4 to 10%.
         2. The cotton belt is resistant to alkali and acid. Cotton cloth is extremely unstable to inorganic acids, even if it is very dilute sulfuric acid, it will be destroyed, but the organic acid is weak and hardly destructive. Cotton cloth is more resistant to alkali. Generally, dilute alkali does not affect cotton at normal temperature, but the strength of cotton will decrease after strong alkali action. The "silked" cotton cloth can be obtained by treating the cotton cloth with 20% caustic soda.
         3. The cotton belt is generally light resistant and heat resistant. In the sun and the atmosphere, the cotton will slowly oxidize, causing the strength to drop. The long-term high temperature action will damage the cotton cloth, but the cotton belt can withstand a short high temperature treatment of 125~150 °C.
         4. Microorganisms have a destructive effect on cotton. It is not resistant to mold.
