Applied linear structure of aramid fiber in warp knitting

Abstract

The invention relates to the technical field of warp knitting screen cloth, in particular to an applied linear structure of aramid fiber in warp knitting. The structure comprises first aramid fiber main threads and second aramid fiber main threads; the first aramid fiber main threads are vertically arranged at equal intervals; the second aramid fiber main threads are horizontally arranged at equal intervals; the first aramid fiber main threads and the second aramid fiber main threads are vertically arranged in a downward crossing manner; the aramid fiber first main threads penetrate through first interpenetrating threads in sequence; the side faces of the first interpenetrating threads are provided with second interpenetrating threads; and the first interpenetrating threads and the second interpenetrating threads are wound in a crossed mode to form an 8-shaped node. The structure has the beneficial effects that by the arranged 8-shaped node and O-shaped winding mode, a connecting mode between threads of traditional mesh cloth is changed; and tightening threads, limiting threads and fixing threads are reasonably interpenetrated into construction structures of mesh cloth threads at equal intervals, so that the overall structure of the aramid warp-knitted mesh cloth is tighter, the aramid warp-knitted mesh cloth can bear relatively large tension, and the service life of the aramid warp-knitted mesh cloth is prolonged.

Description

technical field [0001] The invention relates to the technical field of warp knitting mesh, in particular to the linear structure of aramid fibers applied to warp knitting. Background technique [0002] At present, ordinary materials or some polyester industrial yarns are used in the market to strengthen the strength of the fabric, which cannot meet the production of mesh fabrics that exceed the performance. This product directly uses aramid fiber on the warp knitting is a new breakthrough method. Through special warping and adjustment of the machine, the aramid fiber that was not easy to be woven in the past can be produced in the mesh. [0003] Some existing warp-knitted mesh fabrics are not tightly connected between threads, and the elastic capacity ratio is poor, so that the mesh fabric cannot bear a large tensile force, the tightness of the fabric structure is poor, and its overall strength is poor. Very easy to pull damage. [0004] Therefore, we need the linear struc...
