cotton Backpack webbing In fact, it refers to the fabric made of cotton yarn or cotton and cotton type chemical fiber blended yarn. It has the following characteristics:
1. Microbes can damage cotton fabric. Its performance is that it is not resistant to mold, and the cotton belt will change color and smell after being stored for a long time.
2. The light resistance and heat resistance of cotton belt are general. The cotton cloth will be oxidized slowly in the sun and atmosphere, which will reduce its strength. Long term high temperature effect will damage the cotton cloth, but the cotton belt can withstand 125~150 ℃ temporary high temperature treatment without any impact temporarily.
3. The cotton belt is alkali resistant and acid resistant. Cotton cloth is extremely unstable to acid, even very dilute acid will damage it, but organic acid has weak effect, almost no damage. The cotton cloth is relatively alkali resistant. Generally, the dilute alkali does not affect the cotton cloth at room temperature, but the strength of the cotton cloth will decline after the strong alkali action. Mercerized cotton cloth can be obtained by treating cotton cloth with 20% caustic soda.
4. The cotton backpack webbing is highly hygroscopic and has a large shrinkage rate, which is about 4~10% according to the data.
