PET non woven fabric, also known as non woven polyester fabric, is a kind of non woven fabric and is the most commonly used non woven fabric in daily life. From home textiles to filtration, you don't need it. You probably know it's versatile, but do you know what features it has? What is the difference between it and PP non woven fabric?

1. Introduction of non woven polyester fabric

PET refers to polyester, which is polyethylene terephthalate.Non woven polyester fabric is a kind of non woven fabric, and its raw material is 100% polyester chips. It is made of countless continuous polyester filaments through spunbonding and hot rolling. It is also called PET spunbond filament non woven fabric or PES spunbond non woven fabric, also called one component spunbond non woven fabric.

2. Characteristics of  non woven polyester fabric

First, non woven polyester fabric is a water repellent non woven fabric, and the water repellent performance of non woven fabrics is different according to the size of the gram. The larger and thicker the gram weight, the better the water repellency. If there are water droplets on the surface of the non woven fabric, the water droplets will slide directly from the surface.

Second, high temperature resistance. Because the melting point of polyester is around 260°C, it can maintain the stability of the non woven fabric in the environment where temperature resistance is required. It has been widely used in thermal transfer printing, transmission oil filtration, and some composite materials that require high temperature resistance.

Third, it is a filament non woven fabric second only to nylon spunbond non woven fabrics. Its excellent strength, good air permeability, tensile and tear resistance and anti aging properties have been used by more and more people in various fields.

Fourth, non woven polyester fabric also have a very special physical property: resistance to gamma rays. That is to say, if it is applied to medical products, it can be directly sterilized with gamma rays without destroying its physical properties and dimensional stability, which is a physical property that PP (polypropylene) non woven fabric do not have.

3. The difference between non woven polyester fabric and PP non woven fabric

In terms of raw materials: non woven polyester fabric is a new polyester raw material, namely polyester fiber. There is no additive in the whole production process. It is a very good environmental protection product and belongs to thick non woven fabric. PP non woven fabrics are polypropylene raw materials, namely polypropylene fibers, which are thin non woven fabric. The raw material of PP is cheap, and the raw material of PET is expensive. The waste of PP can be returned to the furnace for reuse, and the waste of PET cannot be returned to the furnace, so the cost of PP is slightly lower.

High temperature resistance: The high temperature resistance of PP fabrics is around 200 degrees, while that of non woven polyester fabric is around 290 degrees, so non woven polyester fabric is more resistant to high temperatures than PP fabrics.

In terms of non woven printing and heat transfer effect: under the same width, PP fabric shrinks more, non woven polyester fabric shrinks less, and the effect is better, so non woven polyester fabric is more economical and wasteful.

Tension, tension, bearing capacity, and the same gram weight: PET non woven fabric

 has higher tensile force, tension and bearing capacity than PP fabric. 65 grams of PET non woven fabric is equivalent to the tensile force, tension and bearing capacity of 80 grams of PP fabric.

Environmental protection: PP fabrics are mixed with recycled PP fabric waste, and PET non woven fabric are all new polyester chips, so PET non woven fabric are more environmentally friendly and hygienic than PP fabrics.

Today, non woven polyester fabric is widely used in various fields. Such as home textiles, packaging, decoration, etc. This article explains the difference between polyester non woven fabrics and PP non woven fabric from the raw materials, properties, and PP non woven fabrics, so that everyone can have a better understanding of them.
