Characteristics of polyester needle punched non-woven fabric-insoluble in organic acids

Polyester needle-punched non-woven fabric has the characteristics of high strength, elasticity, good recovery performance, good air permeability, heat preservation, water absorption, elasticity 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 fabric is an acid-resistant, insoluble material in organic acids. It is stable to concentrations of inorganic acids at low temperatures, but can be dissolved in concentrated sulfuric acid and heated m-formic acid. The solvent is relatively stable and has high chemical stability. Therefore, based on the acid resistance of polyester needle-punched non-woven fabric, it is a material that can be washed without deformation. Widely used in: clothing filling, bedding, cushions, agricultural insulation quilts, geotextiles, masks, automobiles, medical care products, etc.


Each fiber of the polyester needle-punched non-woven fabric is independent, and at the same time it has strong adsorption, good adsorption and dispersion in the medium. Therefore, it can protect and improve the stability of products when applied to different products. It is an ideal reinforcing material.
