Non woven polyethylene fabric, also known as non woven polyethylene geotextile, is the permeable geosynthetic materials made of synthetic fibers by needling or weaving. The finished product is cloth shape, generally 4-6 meters in width and 50-100 meters in length. Nonwoven geotextiles are divided into needle punched nonwoven geotextile and filament nonwoven geotextile. Non woven polyethylene fabric has excellent filtration, isolation, reinforcement and protection, high tensile strength, good permeability, high temperature resistance, freezing resistance, aging resistance, corrosion resistance.
Effect
Nonwoven geotextile is a new generation of cushion protective geosynthetic material specially designed and developed for preventing slope slip in sanitary landfill site. It can effectively prevent ultraviolet damage to chemical fiber and enhance the anti-aging property of nonwoven geotextile; In engineering, it is combined with the rough surface of HDPE film to increase the friction force between the cloth film and play a good application effect.
Case Study
The Philippines, like most countries in the Asia-Pacific region, is grappling with a growing solid waste management problem in its large cities. According to the World Bank, nearly 25 percent of the country’s waste is generated in metro Manila. This issue stems from the rapid increase in consumption of various goods, including food packaging, due to high population density and the widespread use of disposable items. Moreover, many packaging materials contain harmful substances that pose environmental risks. If these wastes are not managed effectively, densely populated urban areas will face an escalating waste crisis.
With a rising population, increased per capita consumption, and ongoing urbanization, the Philippines faces three major challenges in waste management: first, the rapid growth of waste generation; second, changes in the composition of waste; and third, alterations in waste disposal methods. Consequently, the Philippine government has turned to landfills as a primary means of waste management.
Landfills non-woven geotextiles
Landfills often utilize non-woven geotextiles, specifically non-woven polyethylene fabric. This material is made by consolidating polyester chip textile yarn into a non-woven form, which is then subjected to acupuncture to create a 3D arrangement of polyester filaments. This process enhances the fabric’s toughness and ductility. Additionally, the acupuncture technique imparts excellent filtering properties to the non-woven geotextile. The polyethylene material ensures good corrosion resistance. These physical characteristics make non-woven geotextiles highly suitable for applications in landfill engineering, tailings ponds, river and highway construction. Commonly used weights include 200g/m2, 400g/m2, 600g/m2, and 800g/m2.
Negotiation process
The contractor of the Philippine project contacted the salesman through the BPM website. They won the bid for the domestic sanitary landfill project and needed us to provide the technical indicators, samples and third-party testing report of non woven polyethylene geotextile, with emphasis on alkaline resistance. BPM salesman recommended filament nnon woven polyethylene geotextile of 400gsm according to the requirements of the client’s project. After receiving the samples, the customer asked a third-party testing company to test various indicators. Finally, they were very satisfied with our products and fully met the customer’s requirements. Therefore, cooperation was finally reached after communication on quantity, price, delivery date and payment method.
Non-woven non woven geotextiles for landfill sites has the following Characteristics.
- With strong permeability, it can discharge engineering water in time;
- It has good creep resistance and can resist soil acidity and chemical corrosion;
- It has good extension adaptability and can adapt to the environmental soil conditions and fit the surface.
- Itcan play a permanent isolation role;
- Long-term isolation of soil layers composed of different components and properties and prevention of mixing;
- It has frost resistance and load bearing requirements required by construction.
- With good anti-filtration performance and anti-corrosion performance. Water can permeate in all directions without building up pressure. At the same time, it can prevent soil loss and is beneficial to stability and anti-corrosion performance.
- With reliable drainage performance. Because of the fluffiness of the structure, the drainage of geotechnical engineering surface can be effectively controlled.
- With good protection performance. Because of its good puncturing, extensibility and fluffiness, it can effectively protect the waterproof layer from potential mechanical damage.
- With reinforcement performance. The fluffiness and high strength improve the overall stability of the project and increase its strength.
Nonwoven Geotextile Construction and Laying
Non-woven polyethylene geotextile laying is crucial. Protect rolls from damage pre-installation. Store flat, max 4 high, visible ID plates. Cover with opaque material to prevent UV aging. Ensure label and data integrity during storage. Protect from damage in transit. Repair damaged rolls; discard badly worn. Avoid use if exposed to leaking chemicals. Proper laying methods are essential for effectiveness.
- Manual rolling.The cloth should be flat, and the appropriate amount of deformation allowance.
- Filament installation is usually done by lap, suture and welding. The width of suture and welding is generally more than 0.1m, and the lap width is generally more than 0.2m. nonwoven geotextiles that may be exposed for a long time should be welded or sutured.
- The stitching of nonwoven geotextiles. All stitching must be continuous (e.g., spot stitching is not allowed). nonwoven geotextiles must overlap at least 150mm before overlapping. Minimum stitching distance to selvage (exposed edge of material) is at least 25mm.
