The surface of PP non-woven fabrics and PET non-woven fabrics are very similar, and the embossing is usually a small square or sesame pattern. Below, we distinguish the differences between PP nonwovens and PET nonwovens in several ways.

Firstly, the difference in raw materials: PP refers to polypropylene; PET refers to polyester. They are completely different from raw materials.

Secondly, there is a big difference in the application of these two kinds of non-woven fabrics(China Spun bonded Non-woven Manufacturer), but in some respects, they can also substitute for each other. It's just a difference in performance. For example, PET nonwovens are often used as filter materials, but PP nonwovens are hardly used for this purpose. PET non-woven fabrics and PP non-woven fabrics are used for packaging materials, such as gift packaging, flower packaging(Packing Non-woven Fabric Wholesale), and so on.

In addition, the two methods are the same and different in the way of production and processing. Different processing methods determine the final application in most cases. Relatively speaking, PET is more expensive and more expensive.
Compared to PP nonwovens and PP nonwovens(China Non-woven Fabric Manufacturer), the performance has the following differences:

First, the stability of PET non-woven fabric than PP non-woven fabric
Mainly in: strong, wear and other properties. Due to the use of special raw materials for polyester non-woven fabrics, it has been advanced by advanced imported equipment and complicated and scientific processing techniques. It has far exceeded the technical content and requirements of polypropylene nonwovens.
Second, the thermal resistance of PET nonwovens is higher than that of PP nonwovens
Polypropylene non-woven fabric has obvious thermal shrinkage. According to the survey, when the temperature reaches 140°C, there is obvious shrinkage, while the maximum temperature of polyester non-woven fabric can reach about 230°C, which has obvious characteristics compared with polypropylene non-woven fabric. .
Third, the anti-aging period of PET non-woven fabric is longer than PP non-woven fabric
Polyester non-woven fabrics use polyester as raw material, which is resistant to insects, abrasion, and ultraviolet rays. These properties are higher than polypropylene nonwovens.
Fourth, PET non-woven fabrics and PP non-woven fabrics have good air permeability
Compared with polypropylene and other non-woven fabrics, polyester non-woven fabrics have excellent properties such as non-absorbent, non-water-tolerant, and strong air permeability.
