Polyester (PET) spunbonded filament nonwoven fabric is a kind of non-woven fabric, and its raw material is 100% polyester chips. It is made by spinning a number of continuous polyester filaments by spunbond hot rolling. Also known as PET spunbonded filament nonwoven fabric or PES spunbonded nonwoven fabric, also called single-component spunbonded nonwoven fabric.
PET Non-woven Features
First, water repellency. Polyester (PET) spunbonded filament nonwoven fabric is a water-repellent non-woven fabric, and the water-repellent properties of different nonwoven fabrics vary according to the size of the gram. The heavier and thicker the weight, the better the water repellency. If water droplets are on the surface of the nonwoven, the water droplets will slide directly off the surface.
Second, high temperature resistance. Since the melting point of polyester is around 260 ° C, the stability of the outer dimensions of the nonwoven fabric can be maintained in an environment requiring temperature resistance. It has been widely used in thermal transfer printing, transmission oil filtration, and some composite materials that require high temperature resistance.
Third, the intensity is high. Polyester (PET) spunbonded nonwoven fabric is a filament nonwoven fabric second only to nylon spunbonded nonwoven fabric. Its excellent strength, good breathability, tensile tear resistance and anti-aging properties have been used by more and more people in various fields.
Fourth, anti-gamma rays. Polyester (PET) spunbond nonwovens also have a very specific physical property: anti-gamma rays. That is to say, if applied to a medical product, it can be directly sterilized with gamma rays without deteriorating the physical properties and dimensional stability, which is a physical property that the polypropylene (PP) spunbonded nonwoven fabric does not have.
