In this article, we will delve into the specific features and benefits of the geotextile from BPM Geosynthetics, highlighting its contributions to enhancing project efficiency and environmental sustainability.
1. Definition Of 4m Geotextile
Geotextile, also known as geotextile, is a water-permeable geosynthetic material made of synthetic fibers through needle punching. It is divided into woven and non-woven types. Geotextile has excellent filtering, isolation, reinforcement, and protection functions. Additionally, it has high tensile strength, good permeability, and resistance to high temperatures, freezing, aging, and corrosion. Because the material is light and soft, it is easy to transport, lay, and construct.
2. Production Process Of 4m Geotextile
2.1 Raw material selection
2.1.1 Polypropylene (PP):
- Features: Light, corrosion-resistant, suitable for most geotechnical applications.
- Application: Widely used in agriculture, horticulture and soil protection.
2.1.2 Polyester (PET):
- Features: High strength, good durability, anti-ultraviolet and chemical corrosion.
- Application: Suitable for civil engineering projects with high strength requirements, such as roads and water conservancy projects.
2.2 Production process
2.2.1 Raw material preparation:
Use polypropylene particles or other synthetic fibers as raw materials.
2.2.2 Fiber web:
The added polypropylene particles are extruded into continuous fiber filaments. These filaments are then stretched and shrunk. Subsequently, the fibers are cut into staple fibers. These fibers are placed in the machine for flattening. Afterward, the stretched tows are separated by the oscillating wire. Finally, they are evenly laid on the mesh curtain of the web forming machine. This process forms a fiber web with a certain gram weight and thickness.
2.2.3 Needle punching reinforcement:
The fiber web undergoes needle punching for reinforcement. This process is divided into two steps: pre-needling and main needling. Pre-needling targets the fluffy, weak fiber net from web laying. Main needling further strengthens this fiber net.
2.2.4 Post-treatment:
The geotextile, after needle punching reinforcement, undergoes heat setting. This heating stabilizes the fiber cross-linking points. It enhances dimensional stability and deformation resistance. Following heat setting, post-treatment processes are applied. These include singeing and filter pressing. They improve surface finish and air permeability.
2.2.5 Finished product processing:
The processed polyester staple fiber geotextile is trimmed to remove irregular edge parts. This ensures accurate finished product size. Next, chemical oil treatment is carried out as needed. This makes the geotextile smoother and improves micropore distribution. Finally, it is rolled and packed for storage.
2.3 Quality control
2.3.1 Influence of raw materials
High-quality fiber raw materials are essential for high-performance geotextiles. The strength, abrasion resistance, and aging resistance of the fiber determine its mechanical properties and service life. Therefore, BPM strictly controls raw material selection to ensure fiber quality meets relevant standards.
2.3.2 Production process
From carding to web laying and needle punching, each link requires delicate operation. Process parameters such as needle punching density affect its strength. BPM adopts advanced production technology and strict quality control to ensure high-quality products.
2.3.3 Environmental factors
During storage and transportation, geotextiles may be affected by environmental factors. Temperature, humidity, and light can lead to fiber aging and strength loss. Therefore, BPM takes protective measures to ensure stable quality during these stages.
