Characteristics of polyester needle punched non-woven fabrics - insoluble in organic acids
Polyester needle-punched non-woven fabrics have the characteristics of high strength, good elasticity, good recovery performance, good air permeability, heat preservation, water absorption, stretchability, and good hand feeling. It also has good use characteristics at room temperature, that is, it is acid-resistant and insoluble in organic acids.
Polyester needle-punched non-woven fabrics are acid-resistant and insoluble in organic acids. At low temperature, they are very stable to concentrated inorganic acids, but they can be dissolved in concentrated sulfuric acid and heated m-formic acid.
