What is the difference between PP non-woven fabric and PET non-woven fabric

PP non-woven fabric and PET non-woven fabric are two common non-woven materials, which have significant differences in raw materials, properties, and applications. PP non-woven fabric is made from polypropylene, while PET non-woven fabric is made from polyester. The following are the main differences between the two:

1、 Raw materials and characteristics:

1. PP non-woven fabric: Polypropylene is a thermoplastic material with characteristics such as lightweight, chemical corrosion resistance, and good waterproofing. PP non-woven fabric is usually softer and has better breathability, but its high temperature resistance is poor (generally not exceeding 80 ° C).

2. PET non-woven fabric: Polyester fibers have high strength, high temperature resistance (up to 150 ° C or above), and excellent UV resistance. PET non-woven fabric is more durable and suitable for long-term outdoor use.

2、 Production process:

1. PP non-woven fabrics are mostly produced by spunbond or melt blown methods, which are suitable for manufacturing lightweight products.

2. PET non-woven fabric is often processed through needle punching or water punching techniques, resulting in thicker and more suitable products for high-strength applications.

3、 Application scenarios:

1. PP non-woven fabric: commonly used in medical supplies (such as masks, protective clothing), packaging materials, household items (such as shopping bags), and other fields that require high flexibility and breathability.

2. PET non-woven fabric: commonly used in geotechnical materials (such as roadbed reinforcement, drainage maintenance), automotive interiors, filter materials, and other scenarios that require high strength and durability.

4、 Cost and Environmental Protection:

1. PP non-woven fabric has a lower raw material cost, but it is difficult to recycle.

2. PET non-woven fabric is recyclable and environmentally friendly, but the production cost is relatively high.

5、 Performance comparison:

1. Tensile strength: PET non-woven fabric is significantly higher than PP non-woven fabric, suitable for load-bearing scenarios.

2. Weather resistance: PET is not easily aged after long-term outdoor use, while PP is susceptible to UV radiation.

6、 In summary, choosing PP or PET non-woven fabric depends on specific needs: PP is suitable for low-cost, lightweight short-term applications, while PET is more suitable for high-strength, durable long-term projects. Now there are polyester non-woven fabric products in the store, which have high strength, high temperature resistance, and UV resistance, suitable for engineering scenarios such as road reinforcement and drainage maintenance.
