Weaving method and weaving device for multiple-weft high-density water spraying jacquards

Abstract

The invention discloses a weaving method and a weaving device for multiple-weft high-density water spraying jacquards. The weaving device comprises a weaving machine body, a first warp beam, a second warp beam, a jacquard loom, a multiple-arm loom, a heald frame, a plurality of first harness wires, a plurality of second harness wires, a plurality of harness cords, a plurality of harness wire returning springs and at least one weft storing device. The jacquard loom and the multiple-arm loom are installed on the weaving machine body, the plurality of harness cords are arranged on the jacquard loom, the lower ends of the harness cords are connected with the first harness wires, the lower ends of the first harness wires are connected with the harness wire returning springs, and the lower endsof the harness wire returning springs are fixed on the weaving machine body. The first harness wire are provided with first mail eyes, the lower portion of the multiple-arm loom is connected with theheald frame, the second harness wires are arranged in the heald frame, and second mail eyes are arranged on the second harness wires. First warps and second warps are respectively wound on the first warp beam and the second warp beam, the first warps penetrate through the first mail eyes, second warps penetrate through the second mail eyes, the first warps and the second warps form a shed along with movement of the first harness wires and the second harness wires, and wefts on the weft storing device penetrate through the shed. The weaving method and the weaving device for the multiple-weft high-density water spraying jacquards improves definition of a weaving hole (the shed) and achieves good weaving of high-density jacquard fabrics.

Description

【Technical field】 [0001] The invention relates to the technical field of textile technology, in particular to a multi-weft high-density water-jet jacquard weaving method and a weaving device. 【Background technique】 [0002] At present, most of the existing jacquard fabrics have a low warp density, and most of them are single-layer jacquard structures. However, when the existing jacquard devices weave products with a warp density of 140 or more, the number of warp yarns raised varies. The shed is not clear and curved, which affects the normal weft insertion, and is generally single weft weaving. Moreover, when weaving on a wide-width water-jet jacquard loom, affected by factors such as shed opening, vehicle speed, width, and equipment structure, the position of the nozzle is restricted, which is not conducive to multi-weaving water-jet weaving, which greatly limits the product quality. development and production. 【Content of invention】 [0003] The purpose of the present ...

[0002] At present, most of the existing jacquard fabrics have a low warp density, and most of them are single-layer jacquard structures. However, when the existing jacquard devices weave products with a warp density of 140 or more, the number of warp yarns raised varies. The shed is not clear and curved, which affects the normal weft insertion, generally for single weft weaving

Moreover, when weaving on a wide-width water-jet jacquard loom, affected by factors such as shed opening, vehicle speed, width, and equipment structure, the position of the nozzle is limited, which is not conducive to multi-weaving water-jet weaving, which greatly limits the product quality. development and production
