Durable geotechnical cloth preparation process

Abstract

The invention discloses a durable geotechnical cloth preparation process. The durable geotechnical cloth preparation process comprises the following steps that S1, placing is carried out, specifically, cloth is placed on a material placing flat plate in the middle of a machine frame in a fitting mode; then the cloth sequentially penetrates through a leveling plate and a front guide roller, and one end of the cloth is fixed to a rolling shaft; and an upper ironing metal plate and the leveling plate are driven to move downwards by a hydraulic telescopic rod to be fitted on the surface of the cloth. A lower heating plate and an upper heating plate are used for heating a lower ironing metal plate and an upper ironing metal plate at the same time, geotechnical cloth passes through the space between the lower ironing metal plate and the upper ironing metal plate when being conveyed forwards, and the geotechnical cloth can be ironed through the lower ironing metal plate and the upper ironing metal plate; residual broken filaments on the surface of the geotechnical cloth in the geotechnical cloth manufacturing and weaving process are removed at high temperature, so that the surface of the geotechnical cloth is kept flat, and the broken filaments or thread residues are prevented from protruding; and the situation that the geotechnical cloth is torn due to the fact that the thread residues and the broken filaments are prone to being hung on foreign matter in the use process is avoided, and the service life of the geotechnical cloth is effectively prolonged.

Description

technical field [0001] The invention relates to the technical field of geotextile preparation, in particular to a preparation process of a durable geotextile. 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 material geosynthetics. The finished product is cloth-like. Geotextiles are divided into Spun geotextiles and non-woven filament geotextiles. Geotextiles have the characteristics of corrosion resistance, good water permeability, good anti-microbial properties and convenient construction. Geotextiles are widely used in geotechnical projects such as water conservancy, electric power, mines, roads and railways. Specifically Filter material for soil layer separation; drainage material for reservoirs and mine dressing, drainage material for high-rise building foundations; anti-scour material for river dams and slope protection; [...

AI Technical Summary

Problems solved by technology

[0004] The present invention provides a preparation process of durable geotextiles, which can effectively solve the problem that some hairs and thread ends are easily produced on the surface of the geotextiles in the production process of the above-mentioned background technology, which are residual products in the process of weaving and acupuncture. , when paving and pulling, it is easy to get caught in wool and threads, which will cause some small openings in the middle of the geotextile, which will affect the normal use of the geotextile.
