In the geotechnical material industry, there are many kinds of classification of geotextile products, each of which has its own characteristics and concepts. To use geotextile, the first thing we need to do is to understand its basic knowledge. As one of the professional manufacturers, if we want to get further development, we need to better serve our customers. For this, the relevant technical personnel have several types of geotextile products A detailed introduction to the fabric:

1. Short fiber needle punched geotextile is a kind of nonwovens and industrial fabrics. It is made of polyester crimp staple fiber with fiber size of 6-12dan and length of 54-64mm. The nonwoven production equipment is made into cloth by the process of opening, carding, disordering (short fibers interweave with each other), laying mesh (standardized tangle and fixation), acupuncture and other production processes. As long as it is applied to the reinforcement of railway subgrade, maintenance of highway pavement, protection of sports hall, dike, isolation of hydraulic structure, Suidong, coastal beach, reclamation, environmental protection and other projects.

2. Woven geotextile is a kind of geosynthetic material, which is made of polypropylene and polypropylene flat fiber. It is widely used in water conservancy, electric power, harbor, highway, railway construction and other geotechnical engineering.

How many kinds of geotextiles are there? It's really not clear if it's briefly summarized, because there are different bases for the classification of geotextiles, such as the classification according to the manufacturing methods, the classification according to the raw materials, the classification according to the materials and even the classification according to the functions, etc., so if you want to know the types of geotextiles, you need to know the basis for the classification of geotextiles first.

The following is a brief introduction to the performance differences of different kinds of geotextiles according to the manufacturing methods:

1. Short thread needled non-woven geotextile: the obvious advantage of short thread needled non-woven geotextile is aging resistance, which also determines that compared with general geotextile, short thread needled non-woven geotextile has stronger UV radiation. In addition, it has the advantages of good flexibility and simple and quick construction.

The short-term needled non-woven geotextile is mainly used to reinforce the highway, construction, water conservancy engineering and other aspects.

2. Spunbond needle punched nonwoven geotextile: sometimes it is also called nonwoven geotextile directly. Short thread needle punched nonwoven geotextile has the advantages that nonwoven geotextile basically has, in addition, it also has a certain sealing effect.

The main function of spunbond needle punched nonwoven geotextile is to protect, such as in the construction of tunnels, waste disposal and so on. Sometimes it can also be combined with membrane for seepage control.

3. Woven non-woven geotextile: the strength of woven non-woven geotextile is relatively high, that is to say, it is not easy to break and deform. In the face of the impact of some irresponsible small stones on the cloth surface, woven non-woven geotextile has a certain resistance.

The main function of woven non-woven geotextile is reinforcement, which is common in some stone, slope protection and soil improvement and reinforcement.

4. Composite geotextile: in most cases, it is also called composite geomembrane. It is mainly composed of geotextile and plastic film. The function of geotextile is mainly to protect plastic film. Its main feature is impermeability.

Composite geotextile is more widely used in the construction of two cloth and one membrane. Because of its good anti-seepage performance, it is often used in projects such as dams, subway tunnels, artificial lakes and so on.

These are the advantages of four different kinds of geotextiles. In the process of practical application, it is better to choose the geotextiles according to the actual situation and the characteristics of geotextiles.
