Weight range: 10-260gsm
Air permeability: Means air can go through the nonwovens.
the polyester nonwovens can be produced as air filter for automotive, air conditioners to filtering the air.
It is the feature of nonwoven which means the spunbond nonwoven
fabric itself does not absorb any liquid. We also call it
water-repellent or water resistant (waterproof). This does not mean
the water cannot go through the nonwovens. If you want some water
immerses through the nonwoven, you need to choose the lightweight
between 10gsm-25gsm. Whether the water can go through or not depends
on the weight of per square meter. The lighter weight can immerse
easily than the thicker. As this reason, we can use this for
agriculture or horticulture mulch for frost protection or prevent weed
growth(30-50gsm is suitable for this).
High temperature resistant: The melting point of PET spunbond fabric is around 260℃
which is dimensional stability in the high temperature conditions.
As this feature, it is also used as the substrate of composite materials for high temperature lamination.
Ultrasonic composite is also perfect.
Lightweight and durable: Compare to spunbond PP nonwoven fabric it is lightweight and durable. For example, Same weight 50gsm, pet spunbond nonwovens has better strength than PP nonwoven. Technical data of 50gsm pp spunbond nonwovens equals to around 35gsm polyester spunbonded nonwoven fabrics. In some way, you choose polyester spunbond it is also saved the transportation costs because lightweight. (In one container, you can load more products)
Good tensile strength and thin thickness, excellent uniformity, anti-pull and tear, anti UV-and aging, anti-gamma, corrosion-resistant, soundproof, moth-proof and etc.
No additives during the whole production process. So, it is non-toxic to human skin etc and eco-friendly.
