Three-dimensional fabric surface layer reinforcing weaving method and structure thereof

Abstract

The invention discloses a three-dimensional fabric surface layer reinforcing weaving and a structure thereof. Mainly, a knitting machine is used for knitting yarn into three layers of weaving layers comprising a top-end reticular surface layer, a middle belt ply and a bottom-end weaving layer, wherein the top-end reticular surface layer is a reticulate body which is composed of plural main threadsections and an extending section, the main thread sections are overlapped by two coils, and the extending section only comprises single coil yarn formed by connecting plural coils in series; in the weaving process, the yarn of the middle belt ply carries out reciprocating motion between the top-end reticular surface layer and the bottom-end weaving layer; one end of the yarn of the middle belt ply is connected to the main thread section of the top-end reticular surface layer, and the other end is connected to the bottom-end weaving layer; when the yarn of the middle belt ply moves to the extending section, the yarn is lapped with the extending section so as to reinforce the extending section; and then, reciprocating weaving is carried out between the main thread section and the bottom-end weaving layer so as to achieve the purpose of reinforcing the top-end reticular surface layer.

Description

technical field [0001] The invention relates to a three-dimensional fabric surface layer reinforcement weaving method and its structure, especially refers to a kind of yarn passing through the middle support layer and the extension section of the top mesh surface layer overlapped to achieve the reinforcement of the top mesh The three-dimensional fabric surface layer reinforcement weaving method and its structure for the surface layer purpose. Background technique [0002] see Figure 1A , shown in B, is the schematic diagram of existing three-dimensional fabric, and it mainly comprises bottom layer (11), middle layer (12) and top layer (13), and wherein, this top layer (13) is mesh body or polygonal mesh body, and this The mesh body or polygonal mesh body comprises a main line section (131) and an extension section (132). In order to weave the top layer (13) into a mesh body, the main line section (131) is overlapped by two coil yarns. into, and the extension section (132) ...

AI Technical Summary

Problems solved by technology

However, the extension section (132) of the top layer (13) of the existing three-dimensional fabric only includes a single coil yarn, so that the structural strength of the extension section (132) is insufficient, and the extension section (132) is supported by the middle layer (12); When the surface of the top layer (13) is rubbed, the main line segment (131) and the extension segment (132) will be rubbed at the same time because the main line segment (131) and the extension segment (132) are simultaneously supported. , the extension section (132) with insufficient structural strength is easy to break first, causing the mesh body of the top layer (13) to be damaged and lose its function
