What's the difference between filament geotextile and short silk geotextile?

Abstract: Filament geotextile is a kind of geotextile reinforcement material, which is produced by high-quality polyester sheet source and is mainly used in the fields of retaining wall and dike reinforcement. Compared with short silk geotextile, filament geotextile is different from geotextile in six aspects: raw materials, production technology, appearance, product performance, price and national standards. When selecting, it is mainly based on the specific conditions and design requirements of the project. Let's look at the difference between filament geotextile and short silk geotextile. 1. What is filament geotextile?

Filament geotextile refers to polyester filament needle-punched nonwoven geotextile, which is a commonly used environmental protection building material. As a reinforced material, filament geotextile has a large thickness, which can ensure the three-dimensional porosity of geotextile, and is conducive to achieving excellent hydraulic performance. Its bursting strength has great advantages, especially for retaining walls and dikes, and it is an excellent geotextile reinforced material.

2. What's the difference between filament geotextile and short silk geotextile?

Geotextiles are divided into filament geotextiles and short silk geotextiles. Although they are both geotextiles, they are still different in many aspects. The main differences between geotextile filaments and short silk are:

1, differences in means of production

Filament geotextile is produced by high-quality polyester chip source, and the raw materials are granular. Short silk geotextile is made of PET polyester staple fiber, and the raw material is chemical fiber.

2, the difference between the production process

The production process of filament geotextile is that polyester chips are melted, stretched and shrunk, cut into short fibers, and then woven by machine. The production technology of geotextile in short silk is opening, carding, grouping, netting and needling.

3. Differences in appearance

The color of filament geotextile is white, while the fiber of short silk geotextile is short and the color is brighter than that of white geotextile.

4. Differences in performance

The breaking strength of filament geotextile is higher than that of short silk geotextile.

5. Price difference

For geotextiles with the same weight, the price of filament geotextiles is generally higher than that of short silk geotextiles.

6, the difference between applicable standards

The national standard of filament geotextile is geosynthetic filament woven geotextile (GB/T 17639-2008), and the national standard of short silk geotextile is geosynthetic short fiber needled nonwoven geotextile (GB/T 17638-20 17).

3. Which is better, geotextile filament or short silk?

Both filament geotextile and short silk geotextile play a role in strengthening and protecting in engineering. Comparatively speaking, the performance of filament geotextile is better, while short silk geotextile is cheaper, easier to master and not necessarily better. When choosing geotextile, whether to choose filament geotextile or short silk geotextile mainly depends on the specific conditions and design requirements of the project.
