1. What Is Non Woven Geotextile Landscape Fabric?
Non woven geotextile landscape fabric is a synthetic, permeable geotextile designed for geotechnical and landscaping applications. Unlike woven geotextiles, which are crafted by interlacing yarns in a crisscross pattern, non woven geotextiles are produced by bonding fibers through needle-punching, thermal bonding, or chemical processes. This creates a felt-like material with high permeability (100–150 gpm/ft²) and elongation (>50%), making it ideal for filtration and drainage. Typically made from polypropylene or polyester, non woven geotextiles are rot-resistant, UV-stabilized, and chemically inert, with a lifespan of 20–50 years in harsh conditions.
Composition and Manufacturing Process
Non woven geotextiles are manufactured using short or continuous fibers, primarily polypropylene (90% of the market) or polyester. The most common production method is needle-punching, where barbed needles interlock fibers to form a resilient, felt-like structure with 80–90 lbs grab tensile strength (ASTM D4632). Thermal bonding, used for lightweight fabrics (3–5 oz/yd²), applies heat to fuse fibers, enhancing durability by 15%. Chemical bonding, less common, uses adhesives for specialized applications, ensuring 95% resistance to mildew and soil chemicals.
- Needle-Punched: Creates a random fiber network, offering 20% higher water flow than woven fabrics. Thickness: 1–5 mm.
- Thermally Bonded: Produces thinner fabrics (0.5–1 mm), ideal for lightweight applications like garden weed control.
- Chemically Bonded: Enhances durability for heavy-duty uses, with 10% better puncture resistance (ASTM D6241).
These processes result in a fabric that balances strength (80–425 lbs tensile strength) and permeability (0.5–2.0 sec⁻¹ permittivity), tailored to specific project needs.
Key Specifications and Parameters
Non woven geotextile fabrics are categorized by weight, ranging from lightweight (3–5 oz/yd²) to heavyweight (10–16 oz/yd²), each suited for distinct applications. Below are key specifications based on industry standards (ASTM and ISO):
- Weight: 3–16 oz/yd² (100–540 g/m²). Lightweight fabrics (3–5 oz) offer 150 gpm/ft² flow rates, while heavyweight fabrics (10–16 oz) provide 80–100 gpm/ft² but 20% greater strength.
- Tensile Strength: 80–425 lbs (ASTM D4632), with elongation >50% for flexibility under load.
- Permeability: 100–150 gpm/ft² (ASTM D4491), ensuring efficient water flow while retaining soil particles.
- Apparent Opening Size (AOS): 0.075–0.212 mm (ASTM D4751), preventing clogging by 90% of soil particles.
- UV Resistance: 70–90% strength retention after 500 hours of exposure (ASTM D4355).
- Puncture Resistance: 200–800 lbs (ASTM D6241), ideal for rocky terrains.
- Thickness: 0.5–5 mm, with heavier fabrics offering 15% better load distribution.
These parameters make non woven geotextiles versatile for drainage, filtration, and separation, with 95% reliability in preventing soil migration.
