First, water repellency. Polyester (PET) spunbonded filament nonwoven fabric is a kind of water-repellent nonwoven fabric, and its water-repellent performance varies with different weights. The greater the gram weight, the thicker it is, and the better the water resistance. If water drops on the surface of non-woven fabric, the water drops will directly slide off the surface.
Second, high temperature resistance. Because the melting point of polyester is about 260℃, the shape and size of non-woven fabric can be kept stable in the environment where temperature resistance is needed. It has been widely used in heat transfer printing, transmission oil filtration and some composite materials that need high temperature resistance.
Third, high strength. Polyester spunbonded nonwovens are filament nonwovens second only to nylon spunbonded nonwovens. Its excellent strength, good air permeability, tensile tear resistance and aging resistance have been applied by more and more people in various fields.
Fourth, it is resistant to gamma rays. Polyester (PET) spunbonded nonwovens also have very special physical properties: gamma ray resistance. That is to say, if it is applied to medical supplies, it can be directly sterilized by gamma rays without destroying its physical properties and dimensional stability, which is a physical property that polypropylene (PP) spunbonded nonwovens do not have.
