Alyaf A401 is a nonwoven geotextile made from staple polyester fibers that are mechanically bonded through needle punching. The geotextile has a tensile strength of 17 kN/m in the cross direction and 11.2 kN/m in the machine direction, and is UV resistant with a melting point of 256°C. Alyaf geotextiles are manufactured and tested according to ISO quality, environmental, and safety standards. The geotextile is used in applications such as soil separation, drainage, and erosion control.

ALYAF geotextiles are non-biodegradable, have excellent resistance to chemicals and salts present in the soil and are unaffected by prolonged contact with hydrocarbons such as gasoline and diesel. Predicted to be durable for a minimum of 25 years in natural soil with 4 < pH < 9 and soil temperatures < 25° C. 2. These have excellent UV resistance and exhibit strength retention of 70% on test for weathering resistance to EN 12224. 3. As an organization committed to the safe environmental practices we suggest our customers to dispose the used material and the wastes during installation through a certified agency as the material is recyclable. 4. Engineered grades to meet specific project requirements are available upon request. 5.
