Novel geotextile production process

Abstract

The invention discloses a novel geotextile production process, and belongs to the production field of novel geotextile. Compared with a traditional process, positioning and extruding striped hot meltrubber are added to the geotextile outer surface in the novel geotextile production process and soil carrying capacity of the geotextile is convenient to increase, so that the geotextile processed bythe equipment has a good positioning function. Deviation and relative sliding at the appropriate location are prevented from happening, and the normal construction of the geotextile is ensured. Compared with common production process, the novel geotextile production process is added with anti-ultraviolet fiber. The inner material of the anti-ultraviolet fiber is acrylic, and the acrylic has a goodanti-ultraviolet aging effect, is laid on the upper surface of the geotextile through extrusion molding, and is subjected to waterproof spraying to achieve a good waterproof effect.

Description

technical field [0001] The invention relates to the field of production of novel geotextiles, more specifically, relates to a production process of novel 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,...

AI Technical Summary

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
