Geotextile membrane specifications come in 2 main types. Maybe some people don’t really understand membrane geotextiles. However, people who work in the technical field certainly understand the purpose and functions and the differences.
Understand Geotextile Membrane Specifications
Membrane geotextiles are pieces of cloth that come with pores which function for building construction. In general, this membrane geotextile is called permeable, which can be woven or non-woven.
Using this material can make it easier for water to pass through. Actually, the functions of this geotextile membrane are many. Most people only know about its function as reinforcement. However, this material still has many functions that can be used in construction projects by engineers.
The geotextile membrane specifications themselves have the same type of geosynthetic as geogrid or geomembrane. Furthermore, geotextiles are made from polymer materials, namely polyester or polypropylene.
Detailed Geotextile Membrane Specifications
When viewed from the manufacturing method, geotextiles consist of several very varied types. However, there are two types that are most widely used, namely woven and non-woven geotextiles. The following is a clearer geotextile membrane specifications:
1. Non Woven Geotextiles
For woven itself it means woven. This type is divided into several categories of manufacturing methods. Moven geotextiles are developed from synthetic fibers, which are then produced using weaving techniques.
This type of Woven has the characteristics of 2 sets of threads. Long running threads are called wraps. Most of the woven strength of polypropylene is in the form of extruded ribbons.
This type of woven geotextile comes with raw materials in the form of thread or filament fiber. Then it is put together by weaving or plaiting with interrelated constituent processes.
2. Non-woven Geotextiles
Meanwhile, in the non-woven type, the raw materials are put together using a bonding method or an interlocking method. However, Kia can also find non-woven geotextiles which are produced using a combination method.
The next type is non-woven geotextile, which means it is not woven (not woven). Non-woven geotextiles are produced using stable fibers or filament yarns using thermal or mechanical techniques. Apart from that, this type is also processed using mechanics or chemistry. This is certainly different from woven.
Manufacturing Method and Function
One of the main differences between woven geotextile and non-woven geotextile materials lies in the manufacturing method. Woven material is produced using the weaving method.
Thin strips or threads of film are woven together to form a large sheet. Furthermore, repeated weaving will certainly produce a uniform surface appearance.
Meanwhile, non-woven geotextiles are produced using non-woven methods. To make non-woven materials, you can use the bonding method or interlocking.
Specifically for the bonding method, the joining of threads (film layers) is carried out using machines, chemicals and heat. Meanwhile, the interlocking method is carried out using the needle punch or embroidery technique.
In terms of function, the two are quite different. Woven geotextile material has high tensile strength and is able to withstand heavier loads. So it is more suitable for reinforcement and containment functions.
Meanwhile, non-woven geotextiles have main functions which are more like filtration, separation and drainage. This is because the surface tends to be dense with small pores. However, non-woven is permeable to water and gas, and is able to filter fine aggregate particles.
By understanding geotextile membrane specifications which consist of two different materials, we can provide a more precise picture of the use of geotextiles. This will certainly help in infrastructure work.
