There are endless new types of fabrics on the market, and the polyester flannel fabric is one of them. So what are the chemical properties of polyester flannel fabric and so on?
Polyester is very stable to acids (especially organic acids). After soaking in 5% by mass hydrochloric acid solution at 100℃ for 24h, or immersed in 70% by mass sulfuric acid solution at 40℃ for 72h, its strength There is no loss, but it cannot resist the long-term action of concentrated nitric acid or concentrated sulfuric acid at room temperature.
Because the ester groups on polyester macromolecules are easily hydrolyzed by alkali. The fiber can be destroyed by reacting with concentrated alkali at normal temperature and dilute alkali at high temperature, and it is relatively stable to dilute alkali or weak alkali at low temperature.
Of course, polyester flannel fabric has other chemical properties. Because of its stable chemical properties and warmth and comfort, it can also be used as a home textile fabric . www.dfknit.com
