First, polyester (PET) spunbonded filament non-woven fabric is a kind of water repellent non-woven fabric. The water repellency of non-woven fabric is different according to the weight. The bigger and thicker the gram weight is, the better the water repellency is. If there are water drops on the surface of the non-woven fabric, the water drops will fall directly from the surface.
Second, high temperature resistance. Because the melting point of polyester is 260 ° C, in the need of temperature environment, can maintain the stability of non-woven fabric dimensions. It has been widely used in heat transfer printing, transmission oil filtration, and some composite materials that need high temperature resistance.
Thirdly, PET spunbonded nonwovens is a kind of filament nonwovens second only to nylon spunbonded nonwovens. Its excellent strength, good air permeability, tensile, tear resistance and anti-aging properties have been applied to more and more people in various fields.
Fourth, PET spunbonded nonwovens also have a very special physical properties: gamma ray resistance. In other words, if it is applied to medical products, it can be directly disinfected with gamma rays without damaging the physical properties and dimensional stability, which is the physical properties that polypropylene (PP) spunbonded non-woven fabric does not have.
