1. High moisture absorption, large shrinkage rate, about 4~10%
2. Cotton is resistant to alkalis but not to acids. Cotton fabric is extremely unstable to inorganic acids, even very dilute sulfuric acid can cause damage to it. However, organic acids have a weak effect and almost do not cause damage. Cotton is relatively resistant to alkalis, and general dilute alkalis do not affect it at room temperature. However, under the action of strong alkalis, the strength of cotton fabric will decrease. It is often used to treat cotton fabric with a 20% sodium hydroxide solution to obtain "mercerized" cotton fabric.
3. Light and heat resistance are generally average. Cotton fabric will slowly oxidize in sunlight and the atmosphere, causing strength to decrease. Long-term exposure to high temperatures can damage the fabric, but it can withstand brief exposure to temperatures between 125~150℃.
4. Microorganisms have destructive effects on cotton fabrics, which is manifested by their susceptibility to mold.
5. Hygiene: Cotton fiber is a natural fiber, consisting mainly of cellulose, along with small amounts of wax-like substances, nitrogenous compounds, and pectin. Cotton fabrics have been extensively tested and proven to be completely non-irritating and without any adverse effects when in contact with the skin. They are beneficial to the human body and are highly hygienic.
