Spunbond nonwoven geotextile outperforms needle-punch alternatives when it comes to withstanding the stresses of installation, reducing the risk of tearing or weakening. This enhanced durability translates into a prolonged service life for geotextile applications. Spunbond geotextile provides reliable support and reinforcement, maintaining their strength and integrity over time.
1. What Is Spunbond Nonwoven Geotextile？
Spunbond nonwoven geotextile is a specialized material produced through the spunbonding manufacturing method. This process involves extruding filaments onto a collection belt and bonding them using heated rolls, resulting in a smoother, stiffer product with enhanced strength and reduced pore size. Typically appearing in gray color, spunbond nonwoven geotextiles consist of thermally bonded continuous polypropylene filaments. During production, thousands of fine filaments are oriented and bonded together, creating a sheet with unique properties and consistent quality compared to other geotextiles.
The production of spunbond nonwoven geotextile involves an integrated process of web formation, fiber spinning, and bonding, eliminating intermediate steps and streamlining production for increased efficiency and cost-effectiveness. This innovative fabric type has gained rapid popularity in recent years due to its exceptional properties and efficient manufacturing process, holding a significant share in the realm of nonwoven fabric production across various industries.
Spunbond nonwoven geotextile has high tensile strength, puncture resistance, and durability, spunbond nonwoven geotextiles find widespread application in civil engineering and construction projects. These geotextiles play crucial roles in soil stabilization, erosion control, drainage systems, filtration processes, and soil layer separation. With superior physical and mechanical characteristics, including lightweight construction, ease of installation, and resistance to UV degradation and chemicals, spunbond nonwoven geotextiles offer reliable reinforcement and protection in diverse geotechnical applications, ensuring long-term performance in demanding environments.

3. Is Spunbond Nonwoven Geotextilec Waterproof?
Spunbond nonwoven geotextile is not inherently waterproof. Spunbond nonwoven geotextiles are designed to allow water to pass through them while effectively filtering soil particles. However, they can contribute to the overall waterproofing system by providing protection to underlying waterproof layers. Spunbond nonwoven geotextiles act as a mechanical barrier, shielding the waterproof layer from potential damage caused by external factors such as mechanical stress or abrasion. This helps to maintain the integrity and effectiveness of the waterproofing system.
4. Case Study Of Spunbond Nonwoven Fabric Thailand for Dam Project
We received an inquiry from our client in Thailand regarding the use of spunbond nonwoven geotextile for a dam project. The client specifically requested PET material for the geotextile. In response, we provided them with technical data on PET filament spunbond nonwoven geotextile as a reference.
PET filament spunbond nonwoven geotextile is well-suited for dam projects, as it can be applied to the surface of the dam to provide effective anti-scouring protection. By preventing significant damage to the soil layers of the dam caused by erosion, it helps to safeguard the structure from potential collapse. This protective measure enhances the longevity of the dam and reduces the risk of future issues.
