PET polyester non-woven fabric has performance classification

2022-02-26

PET Nonwovens stability is better than that of polypropylene non-woven fabrics
Mainly in: strength, wear resistance and other properties. Because polyester non-woven fabrics are made of special raw materials, they are made by advanced imported equipment and complex and scientific processing technology, which has far exceeded the technical content and requirements of polypropylene non-woven fabrics.
Second, the heat resistance is better than polypropylene non-woven fabrics
Polypropylene non-woven fabrics have obvious heat shrinkage. According to the survey, when the temperature reaches 140 °C, there is obvious shrinkage, while the maximum temperature of polyester non-woven fabrics can reach about 230 °C, which has obvious characteristics compared with polypropylene non-woven fabrics. .
Third, the anti-aging cycle is higher than that of polypropylene non-woven fabrics
Polyester non-woven fabrics are made of polyester, which is resistant to insects, abrasion and ultraviolet rays. The above characteristics are higher than those of polypropylene non-woven fabrics.
4. Has good air permeability
Compared with polypropylene and other non-woven fabrics, polyester non-woven fabrics have excellent properties such as non-absorbent, intolerant of water, and strong air permeability.
The first is the difference in raw materials: PP refers to polypropylene, that is, polypropylene; PET refers to polyester, that is, polyethylene terephthalate.
Secondly, these two kinds of non-woven fabrics are quite different in application, but they can replace 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 polyester non-woven fabrics are higher-end and more expensive.
