With the rise of
non-woven fabrics, the uses of non-woven fabrics are becoming more and more, and their raw materials are also diverse. So how do we choose the right one when we choose non-woven fabrics? It is still necessary to understand the difference of non-woven fabrics produced by different raw materials, so here is the difference between PET and PP non-woven fabrics:
1. The difference in raw materials: PP refers to polypropylene or polypropylene; PET refers to polyester or polyethylene terephthalate.
2. 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.
3. In terms of production and processing methods, these two have the same and different. Different processing methods determine their application in most cases. However, in our daily use, PP non-woven fabrics are widely used and have many uses.
4. PP raw materials are cheap, PET raw materials are expensive, PP waste can be recycled, and PET cannot be recycled, so the cost of PP non-woven fabrics is slightly lower.
5. The high temperature resistance of PP is about 200 degrees and that of PET is about 290 degrees. PET is more resistant to high temperature than PP.
6. Under the condition of tensile force, tension, bearing capacity and the same gram weight, PET has higher tensile force, tension and bearing capacity than PP. 65 grams of PET is equivalent to 80 grams of PP non-woven fabric, but in our daily use,
PP non-woven fabric can meet most of the needs.
7. From the perspective of environmental protection, PP can be mixed with PP waste that is returned to the furnace, while PET is all new polyester chips. PP is more environmentally friendly, more hygienic and has stronger regeneration performance.
The above is the difference between the two materials of non-woven fabrics. It can be seen that the difference between the two is relatively large, so when we choose the non-woven fabric to be used, we need to make a suitable choice according to our own needs. .
