Geotextile Selection: Filament or Short Silk?
For non-woven geotextile, according to different processes, there are mainly two types of products on the market: Filament Geotextile and Short Silk Geotextile. Due to the differences in their physical properties, customers can choose according to their own needs. Below are the general differences between the two products：
| Differences | Filament geotextile | Short silk geotextile |
| 1. Base material | PP or PET | PP or PET |
| 2. Process | After melting, spun into a web and then reinforced with needles | Mixed from short fiber into a web, then reinforced with needle felting |
| 3. Appearance | continuous fibers, even and tidy surface | distributed short fibers in a chaotic manner, giving a fluffy feeling |
| 4. Performance | The overall load distribution is uniform with high strength in all aspects; good toughness and elongation; strong bonding, fatigue resistance and durability; uniform pore structure and good filtration and drainage capacity. | All performances are lower than filament geotextile under the same specification. |
| 5. Application | Projects with high requirements for performance and long expected life, such as high-speed railways, high-grade highways and large reservoir embankments. | For engineering with general performance requirements, ordinary highway subgrade, drainage ditches and slope greening. |
Based on the above comparison, it can be seen that the overall performance of filament geotextile is superior to that of short silk geotextile. However, due to the complex process of filament geotextile, the investment is higher. Therefore, under the premise of meeting performance requirements, short silk geotextile can also achieve good protection, filtration, breathability and drainage.
Zhonglong Environmental Protection has production lines for both products, offering a width selection of 3-6m and a unit area quality specification of 100-800g. Therefore, it is important to clarify the needs when making a purchase to avoid additional cost.
