PET is a milky white or light yellow, highly crystalline polymer, commonly known as polyester. The surface is smooth and shiny. It has excellent physical and mechanical properties in a wide temperature range. The long-term use temperature can reach 120°C. The electrical insulation is excellent. Even at high temperature and high frequency, its electrical properties are still good, but the corona resistance is poor. Creep resistance, fatigue resistance, friction resistance, and dimensional stability are all very good. PET non-woven fabric is made by spunbonding and hot rolling using this material.
If there are water droplets on the surface of the non-woven fabric, the water droplets will slide directly off the surface. And high temperature resistance. Because the melting point of polyester is around 260°C, pet non-woven fabrics can maintain the stability of non-woven fabric dimensions in environments that require temperature resistance. It has been widely used in heat transfer printing, transmission oil filtration, and some composite materials that require high temperature resistance. It is a filament non-woven fabric second only to nylon spunbond non-woven fabric. The excellent strength, good air permeability and anti-aging properties of PET non-woven fabrics have been used by more and more people in various fields.
