Why Are PET Non Woven Fabric Generally White Or Transparent?

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. It has excellent electrical insulation. Even at high temperature and high frequency, its electrical properties are still good. Creep resistance, fatigue resistance, friction resistance and dimensional stability are all very good. PET Nonwoven Fabric is made of this material by spunbond hot rolling.

If there are water droplets on the surface of the Non Woven Fabric, the water droplets will slide directly from the surface, and it is resistant to high temperature. Because the melting point of polyester is around 260 ° C, Polyester Non Woven Fabric can maintain the stability of the Nonwoven Fabric ' s external dimensions in an environment that requires temperature resistance. It has been widely used in thermal transfer printing, transmission oil filtration, and some composite materials that require high temperature resistance. It is a kind of filament nonwoven fabric second only to nylon Spunbond Nonwoven. The excellent strength, good air permeability and anti - aging performance of PET Non Woven Fabric Raw Material have been used by more and more people in various fields.
