Embodiment Construction

[0019] Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, the same numerals in different drawings refer to the same or similar elements unless otherwise indicated. The implementations described in the following exemplary examples do not represent all implementations consistent with the present invention. Rather, they are merely examples of means consistent with aspects of the invention as recited in the appended claims.

[0020] This embodiment provides a method for producing a composite non-woven fabric warp-knitted grid, comprising: weaving the longitudinal ribs of the warp-knitted grid with the non-woven fabric through a warp-knitting machine, and the longitudinal ribs of the warp-knitted grid pass through The warp-knitted thread and the non-woven fabric are warp-knitted together. Here, the warp-knitted thread may be yarn or co...

Abstract

The invention provides a composite non-woven fabric wrap-knitted grid and a production method thereof. A backing fabric of a hot-rolled and spunbonded non-woven fabric and a common wrap-knitted grid are knitted together through a warp knitting machine, advantages of the backing fabric of the hot-rolled and spunbonded non-woven fabric and the common wrap-knitted grid are integrated, in a civil engineering project, effects of reinforcing and dispersing stress can be achieved, the strength of knots of the warp-knitted grid is enhanced with the aid of features of isotropy and high strength of the non-woven fabric, meanwhile, the filtering performance is good, water and soil loss of a civil engineering base material is avoided effectively, and improvement of integral quality and prolongation of the service life of the civil engineering project are greatly guaranteed and promoted.

Description

technical field [0001] The invention relates to the technical field of grid processing, in particular to a composite non-woven fabric warp-knitted grid and a production method thereof. Background technique [0002] Glass fiber grid (abbreviated as EGA) is the abbreviation of glass fiber geogrid. Fiberglass grid is an excellent geosynthetic material used for road surface reinforcement, old road reinforcement, roadbed reinforcement and soft soil foundation. It has become an irreplaceable material in the application of dealing with reflective cracks in asphalt pavement. This product is a semi-rigid product made of high-strength alkali-free glass fiber through the international advanced warp knitting process and then surface coated. It has high tensile strength and low elongation in the two directions of warp and weft, and has excellent properties such as high temperature resistance, low cold resistance, aging resistance, and corrosion resistance. It is widely used in asphalt ...
