What is Polypropylene Geotextile?

Polypropylene geotextile is a permeable geosynthetic material processed from polypropylene (PP) fibers. 

It is widely used in highways, railways, water conservancy, and environmental protection, primarily serving functions like reinforcement, separation, filtration, drainage, and protection.

Manufacturing Process and Applications of Nonwoven Polypropylene Geotextile

Manufacturing Process: Composed of polypropylene staple fibers or filaments arranged randomly through mechanical entanglement (needle punching) or thermal bonding, resembling felt or tissue paper.

Core Characteristics: Why Polypropylene?

Polypropylene (PP) is a highly common plastic (e.g., household plastic buckets, tableware, and many other items are made from PP). It is chosen for geotextile production due to its outstanding properties:

1. Exceptional Chemical Resistance: Tolerant to acids, alkalis, salts, and chemicals, ideal for active environments like landfills, with minimal degradation.

2. Mold and Bacteria Resistant: Polypropylene offers no nutrients for microorganisms, preventing mold and insect infestation for a longer lifespan.

3. Lightweight yet High Strength: Excellent strength-to-weight ratio, making the geotextile easy to transport and install while maintaining high tensile and tear resistance.

4. Hydrophobic: Does not absorb water; allows free flow through its pores, meeting drainage and filtration needs without retaining moisture.
