PET polyester non-woven fabric has:
1. Stability is better than polypropylene non-woven fabric
Mainly manifested in: strength, wear resistance and other properties. Because polyester non-woven fabrics use special raw materials, they are produced by advanced imported equipment and complex and scientific processing techniques, which have far exceeded the technical content and requirements of polypropylene non-woven fabrics.

2. Heat resistance is better than polypropylene non-woven fabric
Polypropylene non-woven fabric has obvious thermal shrinkage. According to investigation, there will be significant shrinkage when the temperature reaches 140°C, while the maximum temperature of polyester non-woven fabric can reach about 230°C, which has obvious characteristics compared with polypropylene non-woven fabric.

3. The anti-aging cycle is higher than that of polypropylene non-woven fabric
Polyester non-woven fabric is made of polyester, which is resistant to insects, abrasion, and ultraviolet rays. The above characteristics are higher than polypropylene non-woven fabrics.

4. It has good air permeability
Compared with polypropylene and other non-woven fabrics, polyester non-woven fabric has excellent properties such as non-absorbent, incompatible with water, and strong air permeability.
The first is the difference in raw materials: PP refers to polypropylene, which is polypropylene; PET refers to polyester, which is polyethylene terephthalate.
Secondly, these two kinds of non-woven fabrics are quite different in application, but they can be substituted for each other in some aspects. It's just a difference in performance.
In addition, in the way of production and processing, these two have the same and different. Different processing methods determine the final application in most cases. Relatively speaking, PET is more high-end and more expensive.
