Production technology and characteristics of woven geotextile application geotextile is a kind of building material that can be used in geotechnical engineering after cement, wood and steel; It has the functions of reinforcement, drainage and protection; With the arrival of the peak of China's infrastructure construction, this material is facing unprecedented opportunities.

There are many kinds of geotextiles, and the classification methods are different. For example, according to the different production processes, they can be divided into knitted, nonwoven and woven geotextiles. In this paper, we mainly discuss the performance and production process of woven geotextiles; Woven geotextile is made of two groups of filaments or flat strips, which can be divided into single layer and double layer; The main raw material is polypropylene flat silk cloth, supplemented by nylon high loom fabric. The commonly used specifications in the project are generally 200-500g / ㎡, with a width of about 4m.

The production process of single-layer woven geotextile: polymer chip particles → filament (or flat) warp yarn → particle storage → spinning → overall weaving → inspection and finishing → finished products. Conventionally, single-layer woven fabric is also known as geotechnical filter fabric; And the double layer is called the geotextile bag.

Woven geotextile has excellent heat in high strength applications such as reinforcement, reinforcement and erosion prevention; It is mainly used for the treatment of railway and highway disease sections and sections with soft soil; Or slope protection and reinforcement of river banks and dams; Or the construction of airport runways and artificial islands; The reason why it is so widely used is that it has the following characteristics: 1. Good stress-strain relationship; 2. Stable structure; 3. Good filtering effect; Although this material has many advantages, its production process is complex, its output is low, and its cost is high, so it will be prohibitive for projects with low budget.
