What are the ingredients of PP non-woven fabrics?
The main component is polypropylene, and a good non-woven fabric is made of melted polypropylene. ~ But some of the non-woven fabrics will be added calcium carbonate manufacturers, so the quality will be a lot worse, if you want to use it in the hygiene products must pay attention!

Comparison of (PP) Polyester Nonwovens and (PET) Propylene Nonwovens
1.PP material is cheap, PET material is expensive, PP waste can be recycled. PET is not reinstated, so the cost of PP is slightly lower.
2. PP high temperature is about 200 degrees, while PET is about 290 degrees, PET is more resistant to high temperature than PP.
3. Non-woven printing, thermal transfer effect, the same wide PP shrinkage, PET shrink PET effect is better, PET is more wasteful and less.
4. Tensile force, tension, bearing weight, same weight, PET tensile strength, tensile strength, loading capacity. 65 grams of PET is equivalent to 80 grams of PP tension, tension, loading capacity.
5. Environmental protection point of view, PP due to doping back to PP waste, PET all new polyester chips, PET is more environmentally friendly and sanitary than PP.
