Polyester microfiber has a series of excellent properties, such as high fracture strength and elastic modulus, moderate resilience, excellent thermal setting effect, good heat resistance and light resistance. The melting point of polyester fiber is about 255 ℃, the glass transition temperature is about 70 ℃, the shape is stable under a wide range of end-use conditions, the fabric has washability, in addition, it also has excellent resistance (such as resistance to organic solvents, soap, detergent, bleach, oxidant) and good corrosion resistance, stable to weak acid, alkali and so on, so it has a wide range of use and industrial applications.
Polyester microfiber is widely used as civil fabric and industrial fabric because of its high strength such as
crib bumper pads. high modulus and low water absorption. As a textile material, polyester staple fiber can be pure spinning, but also especially suitable for blending with other fibers; it can be mixed with natural fibers such as cotton, hemp and wool, as well as with other chemical staple fibers such as sticky fiber, acetate fiber, polyacrylic fiber and so on.
