The Production Method of Geotextile

The production of geotextiles has its own characteristics and can be divided into several types. The main advantages of the material include high strength and durability, which facilitates its use in construction projects of any level of complexity.

Geotextiles are synthetic materials. This type of building material has a wide range of uses. This is possible because of the versatility of geosynthetics and a host of positive qualities.

The production method of geotextile

There are two main methods of creating and producing geotextiles: organic woven and non-woven. The classification of building materials varies according to the raw materials used and the method of manufacture.

Raw materials can be of the following types:

Polyester;

Polypropylene fibers;

glass fiber;

A blended thread that contains wool or cotton. the

Geotextiles based on polymeric materials are considered to be of the highest quality and most durable. It is this type that is used in construction as the most durable. The polyester used in the production of geotextiles is a recycled secondary raw material. This option is a short line with layers of links. The structure is wool-like and the color can be any color including beige, black or brown.

Polypropylene requires primary raw materials. In this case, a continuous type of thread is formed, increasing the geotextile’s strength and creating a dense, lint-free structure. Color scheme refers to white or gray. The first production method is traditional. The lines are intertwined with each other, which allows you to adjust the size and density of the cells. A characteristic of this material is considered high tensile strength due to its good reinforcement properties.

Nonwoven geosynthetics need mechanical or thermal action in the form of polyester or polypropylene fiber bonds. Depending on the type of geotextile production, there are several types of such materials, , needle punched and bonded. Hydraulic bonding is rarely used. This is a new technology that has not yet become widespread.

The production of Nonwoven Geotextiles is divided into areas where one method or another is used. the

Geotextile Origin

The weaving method is used everywhere because it belongs to the traditional method. Nonwovens are obtained by needling or thermal bonding. According to the production characteristics of geotextiles, there are geographical divisions.

For example, needle-punched geotextiles need the use of needle presses. The perforation process allows the fibers to penetrate the different layers, giving the material a similar density to felt. This type of fabric has a good filtering ability, and water can pass in both directions, especially in the longitudinal and transverse directions. The main application for this fiber will be drainage systems. This method of production is common in most high-tech countries, including the European Union.

Thermal bonding is an alloy of polypropylene fibers. This method is most common in Asian countries and CIS countries.

Two methods of manufacturing geotextiles make obtaining materials with different properties possible. Needle-punched geotextiles have a high filterability level, making them suitable for any soil. But at the same time, its strength is not enough. For this reason, it needs to be compensated by adding reinforced mesh to the structure.

Heat-treated materials increase in strength, but only allow water to pass through. Due to its properties, this geotextile is used for soil reinforcement.

Each version of geosynthetics has its own application direction. This allows us to consider universal materials.

Application fields of geotextiles

The range of building materials is very large.

Range of use:

Construction of automobile and railway roads and runways;

Laying of paving stones and slabs;

foundation formation;

Needle-punched geotextiles are required for drainage systems and filtration facilities;

Medications in the form of disposable clothing and bedding need two or three layers of bonded geotextiles;

hygiene products;

Needle-punched geotextiles are used in agriculture, where necessary with durable covering materials;

Use of cheap geotextiles made of polyester or blended fibers in the furniture production process;

Filters are required for household appliances, and most technical equipment is made of geosynthetics;

materials used for packaging;

Arrangements for various communications related to the construction process.

Beyond these areas, there are many more options for using geotextiles. An example is the improvement of a piece of land. Due to the good properties of this material, it is often used in landscape design.

Geosynthetics are considered popular materials due to their positive qualities including cost-effectiveness and low price. It should be borne in mind that this geotechnical material is completely safe and is considered one of the most friendly materials.
