A production process of geotextile

Abstract

The invention discloses a production process of geotextiles, which belongs to the field of production of new geotextiles. It is a production process of geotextiles, which increases the positioning and extrusion of striped hot-melt rubber on the outer surface of geotextiles in the traditional process, It is convenient to increase the soil-carrying capacity with the soil, so that the geotextile processed by this equipment has a good positioning function, which ensures that it is not easy to shift and relative sliding at the appropriate position of embedding, and ensures the normal construction of the geotextile. Compared with the common production process, anti-ultraviolet fiber is added in this process. The inner material of anti-ultraviolet fiber is acrylic fiber, which has good anti-ultraviolet aging effect, and is laid on the upper surface of geotextile by extrusion molding, and is sprayed with waterproof Under the action of water, it can achieve good waterproof effect.

Description

technical field [0001] The invention relates to the field of production of new geotextiles, more specifically, to a production process of geotextiles. Background technique [0002] Geotextile, also known as geotextile, is a permeable geosynthetic material made of synthetic fibers through needle punching or weaving. Geotextile is one of the new geosynthetic materials. The finished product is cloth-like, with a general width of 4-6 meters and a length of 50-100 meters. Geotextiles are divided into woven geotextiles and non-woven filament geotextiles; [0003] The geotextile rolls should be protected from damage before installation and unfolding. The geotextile rolls should be stacked in a leveled place without water accumulation, and the stack height should not exceed the height of four rolls, and the identification sheet of the roll can be seen. Geotextile rolls must be covered with an opaque material to protect against UV aging. During the storage process, the integrity o...

Problems solved by technology

[0005] The production process for geotextiles in the prior art generally includes steps such as raw material hot-melt polymer, extrusion treatment, rotating spinneret, laying conveyor belt, hot pressing treatment, follow-up treatment, etc., and few of them carry out anti-ultraviolet operation, and Without anti-displacement treatment, the anti-ultraviolet performance of geotextiles manufactured in this way is very poor. During the construction process of geotextiles, it is easy to be affected by external influences and cause partial aging, and after local aging, it is difficult to protect the geotextiles The construction of the cloth is regularized;

[0006] However, the geotextiles produced by the existing geotextile production process are damaged and difficult to locate due to external force majeure factors during the pre-embedding process, which is inconvenient for construction, and is prone to offset and relative sliding at the appropriate position for embedding. , resulting in later project quality problems
