Description

Technical Field

[0001] This utility model belongs to the field of long filament geotextile technology, and specifically relates to a shaped fiber structure for making long filament geotextiles. Background Technology

[0002] Geotextiles are a widely used building material in civil engineering, primarily used for soil reinforcement, preventing soil erosion, and controlling groundwater levels. Traditional geotextiles are mainly made from ordinary round fibers, produced through processes such as extrusion, stretching, and crimping, and then manufactured using techniques like cross-laying and needle punching. However, geotextiles made using this traditional method suffer from insufficient strength and poor permeability / filtration due to the uniform, regular circular fiber shape and inadequate fiber entanglement during use, thus failing to meet certain specialized engineering requirements. Summary of the Invention

[0003] In order to overcome the shortcomings of the prior art, this utility model provides a shaped fiber structure for making long filament geotextiles.

[0004] This utility model is achieved through the following technical solution: A profiled fiber structure for manufacturing filament geotextiles includes a filament fiber body, characterized in that: a plurality of small triangular protrusions and large triangular protrusions arranged at intervals are integrally connected to the outer ring of the filament fiber body.

[0005] There are four small triangular protrusions and four large triangular protrusions.

[0006] The central angle of the arc connecting the small triangular protrusion to the filament fiber body is 30°, and the central angle of the arc connecting the large triangular protrusion to the filament fiber body is 60°.

[0007] The vertex of the small triangular protrusion is higher than the vertex of the large triangular protrusion.

[0008] The beneficial effects of this invention are: the protrusions make the outer circumference of the filament fibers irregular, which allows the fibers to become more entangled during the web laying and needle punching process, thereby improving the strength of the geotextile. Compared with traditional geotextiles, this geotextile has better performance in soil reinforcement, soil erosion prevention and groundwater level control. Attached Figure Description

[0009] The present invention will be further described below with reference to the accompanying drawings.

[0010] Appendix Figure 1 This is a schematic diagram of the structure of this utility model; In the image, there is 1 long filament fiber body, 2 small triangular protrusions, and 3 large triangular protrusions. Detailed Implementation

[0011] The attached figure illustrates a specific embodiment of this utility model. This embodiment includes a filament fiber body 1, with a plurality of small triangular protrusions 2 and large triangular protrusions 3 integrally connected to the outer ring of the filament fiber body 1 at intervals. There are four small triangular protrusions 2 and four large triangular protrusions 3. The central angle of the arc connecting the small triangular protrusions 2 to the filament fiber body 1 is 30°, and the central angle of the arc connecting the large triangular protrusions 3 to the filament fiber body 1 is 60°. The apex of the small triangular protrusion 2 is higher than the apex of the large triangular protrusion 3.

[0012] This invention utilizes a profiled fiber structure for manufacturing long-filament geotextiles. Polyester chips are used as raw material, and the spinneret cross-section is made to match the cross-section of the profiled fiber, thereby extruding the profiled fiber. The profiled fiber is then randomly laid into a web and needle-punched to obtain the polyester long-filament geotextile. Irregular small triangular protrusions 2 and large triangular protrusions 3 are arranged on the outer circumference of the long-filament fiber body 1. The outer circumference is irregular, and the small triangular protrusions 2 and large triangular protrusions 3 are spaced at different heights, creating an undulating effect. During the web laying and needle-punching process, the fibers can more effectively entangle and wrap, thereby improving the strength of the geotextile.
