Geotextile non-woven fabric is one kind of geotextile material. Called non-woven because this material is not produced through the woven method. In the woven geotextile type, the yarn or filament fibres, which are the raw materials, are united by weaving. That means each component yar in interconnected.
On the other hand, the raw materials in the non-woven geotextile are united by using the bonding or interlocking method. Sometimes you can also find non-woven geotextiles that are produced by a combination method. The bonding method requires support from machines, chemicals, solvent, heat, or a combination of these.
While the interlocking method generally uses the needle punch technique. Generally, the materials used to produce geotextile are Polypropylene, Polyester, or the combination of both. On this chance, we’d like to share with you the functions of non-woven geotextiles.


Drainage
Non-woven geotextile fabric is used as a passive element to bring liquids or gases. Non-woven geotextile can independently carry out this drainage function without having to be mixed with additional substances. However, this non-woven material is sometimes combined with other elements to get optimum results. For example, drainage cores.
The combination of perforated non-woven with drainage cores will increase the drainage capacity. This combination is often called geo-composite drainage.
Filtration
Another function of non-woven geotextile fabric is for filtration. When it comes to this function, non-woven materials are used to hold soft aggregate particles. Filtration will prevent smooth particles from grinding or washing. Both elements, which are aggregates and liquids, will separate without having to break the original structure.
This filtration function was the geotextile’s main function back in the mid-1960s. The use of geotextiles at that time was massive, especially in Europe. One of the countries that massively use non-woven geotextiles is the Netherlands. Around 50% of Netherland territories are below sea level. This makes this country prone to tidal floods, where sea water gets into the land.
Geotextile materials are added to the dam structure built along the beach to get the best protection. This way, Dutch lands will not sink.
Separation
Non-woven geotextile is used for separating two layers of soil that have different characteristics. By adding non-woven geotextile as a separator, the fine soil layer will not get into the permeable granular layer. In a nutshell, the fine layer will not be washed away by water. If the fine layer isn’t washed away, its position will remain and won’t get mixed with other layers with different particle sizes.
Separation of non-woven geotextile materials is necessary to ensure the long-term performance of the construction structure. The most common applications of this function are sea walls, dam walls, railroad tracks, and highway foundations.
Non-woven geotextile is normally available in the form of unwoven sheets. In the construction industry, this material is also known as filter fabric. The main advantage of non-woven geotextile is that it has quite a large tensile strength and is resistant to microorganisms and UV rays. It also comes with a permeability property. That’s all that you need to know about geotextile non-woven fabric.
