Imported spunbond non-woven fabric is a non-toxic, odorless, milky white, highly crystalline polymer. It is one of the lightest varieties of all plastics at present. It is particularly stable to water, with a water absorption rate of only 0.01% in 14 hours in water.
The molecular weight is about 80,000 to 150,000, and the formability is good.
It has good heat resistance, with a melting point of 164~170℃, and the products can be sterilized at temperatures above 100℃.
It will not deform at 150℃ without being affected by external force.
The embrittlement temperature is -35°C. Embrittlement will occur below -35°C, and the heat resistance is not as good as PE.
Imported spunbond non-woven fabrics are resistant to high temperatures.
Because the melting point of polyester is around 260°C.
In environments where temperature resistance is required, the stability of the outer dimensions of the non-woven fabric can be maintained.
It is also a water-repellent non-woven fabric.
The water-repellent properties of non-woven fabrics vary depending on the weight.
The greater the weight and thickness, the better the water repellency.
If there are water droplets on the surface of the non-woven fabric, the water beads will slide directly from the surface.
If you want the non-woven fabric to allow some moisture to pass through, you can choose our thin-weight non-woven fabric.
In some cases, waterproof.
