There are significant differences between long-filament geotextile and short-filament geotextile

Release time:

2024-11-01

There are significant differences between long-filament geotextile and short-filament geotextile in many aspects. The following is a detailed comparative analysis:

1. Raw materials

Long-filament geotextile: The raw material is polyester chips, which are granular in shape.

Short-filament geotextile: The raw material is polyester fiber or other chemical fiber materials.

2. Production process

Long-filament geotextile: The production process is relatively complicated. First, the polyester chips are melted, and the fiber filaments are extruded, then stretched and shrunk, cut into short fibers, and then processed by textile methods and machine weaving. The process also includes steps such as needle punching and thermal bonding.

Short-filament geotextile: The production process is relatively simple, including opening, combing, messing (short fibers are intertwined with each other), laying (standardized entanglement and fixation), needle punching and other processes, and finally made into cloth.

3. Appearance

Long-filament geotextile: The color is usually white, and the surface fibers are long and visible to the naked eye.

Short-filament geotextile: The color can also be white, but the color may vary depending on the standard. In addition, there are short-filament geotextiles in black, dark green, grass green and other colors. Its surface fiber is shorter.

4. Technical indicators and performance
Long-filament geotextile: It has higher technical indicators, such as acid and alkali resistance, breaking strength, bursting strength and friction coefficient, which are better than short-filament geotextile.
Short-filament geotextile: Although the technical indicators are slightly lower, it still has good reinforcement, protection, isolation, drainage, filtration and other functions.

5. Price
Long-filament geotextile: Due to the high price of raw materials and complex production process, the price is usually more expensive than short-filament geotextile.
Short-filament geotextile: The price is relatively low and suitable for some engineering projects that do not have particularly high performance requirements.

6. Application field
Long-filament geotextile: Due to its excellent physical and chemical properties, it is widely used in highways, railways, civil engineering, water conservancy projects, environmental protection projects and other fields. Especially in engineering projects that require high strength, high durability and high stability, long-filament geotextile has more advantages.

Short-filament geotextile: It also has a wide range of applications, such as reinforcement of railway roadbed, maintenance of highway pavement, protection of sports halls and dams, etc. Its price advantage makes it more competitive in some engineering projects that do not have particularly high performance requirements.

In summary, there are significant differences between long-filament geotextiles and short-filament geotextiles in production materials, production processes, appearance, technical indicators and performance, prices, and application areas. When choosing, comprehensive consideration should be given to the needs and budget of the specific engineering project.
