Environment-friendly high-strength sludge fence filter cloth

Abstract

The invention discloses environment-friendly high-strength sludge fence filter cloth which is prepared in the following steps: step A, preparing warp yarns and weft yarns: preparing high-strength silkthreads with an extrusion wire drawing machine; step B: beaming; step C: weaving: weaving the warp yarns and the weft yarns on an upper layer as well as the warp yarns and the weft yarns on a lower layer according to a law of three upper-layer yarns and one lower-layer yarn, wherein the arrangement ratio of the upper-layer warp yarns to the lower-layer warp yarns is 1:1, and the arrangement ratioof the upper-layer weft yarns to the lower-layer weft yarns is 1:1; step D, threading a tape: threading strip fabric into a double-layer part; step E: inspecting the appearance of geotechnical clothafter tape threading. According to the fence filter cloth, the geotechnical cloth is enabled to have the double-layer part and a single-layer part, and upper-layer fabric is connected with lower-layerfabric by the single-layer part, so that the connection strength of the upper layer and the lower layer is improved. Additionally, the strip fabric is threaded into a cavity formed by the double-layer part, so that the shading rate of the double-layer part can be improved, and the weft strength of the double-layer geotechnical cloth when in use is improved. The whole process is simpler than a fixing manner of bonding or sewing.

Description

technical field [0001] The invention relates to the technical field of geotextile preparation, in particular to an environment-friendly high-strength mud fence filter cloth. Background technique [0002] Fence cloth is mainly used for water and soil conservation of dams, rivers, creeks, etc. The density of the single-layer structure meets the pore size requirements of water and soil conservation, which not only ensures that the water flow can pass through the cloth surface slowly, but also filters most of the silt to ensure that the water and soil are not lost. At the same time, the double-layer structure is very strong, and the large-area fence connected by belts can effectively resist strong impacts such as strong winds and waves in harsh environments. The material itself is degradable polypropylene, which is safe and environmentally friendly. [0003] When the strength of the single-layer silt fence cloth cannot meet the requirements, an environmentally friendly high-st...

AI Technical Summary

Problems solved by technology

[0003] When the strength of the single-layer silt fence cloth cannot meet the requirements, an environmentally friendly high-strength silt fence filter cloth is required. In the conventional environmentally friendly high-strength silt fence filter cloth, two layers of geotextiles are glued or sewn together. Composite, but this method will increase the production cost and the production process is unreasonable
