Cotton cloth is extremely unstable to inorganic acid, even very dilute sulfuric acid will damage it, but organic acid has weak effect and hardly destructive effect. Cotton cloth is more resistant to alkali. Generally, dilute alkali has no effect on cotton cloth at room temperature, but the strength of cotton cloth will decrease under the action of strong alkali. 20% caustic soda solution is often used to treat cotton cloth to obtain “mererized” cotton cloth; light resistance and heat resistance are average. Cotton cloth will be slowly oxidized in the sun and the atmosphere, reducing its strength. Long-term high temperature action will damage the cotton cloth, but it can withstand short-term high temperature treatment at 125~150℃.
