Problems solved by technology

At present, most of the changes in thickness of composite materials are adopted. The method of bonding is not a whole, the shearing ability between layers is poor, strong and weak rings are prone to appear, and the service life is low.

Embodiment Construction

[0028] The three-dimensional fabric of the same width and different thickness according to the present invention will be further described below in conjunction with a specific example.

[0029] The material is composite yarn. Firstly, nine layers of angle interlocking fabrics are designed, the warp density is designed to be 180 threads / 10cm, and the weft density is 18 threads / 10cm per layer. The number of fabric layers is 9 layers, the number of required heald frames is 10, and the warp is threaded according to the straight-through method. Then design the weave diagram of the 8-layer warp angle interlocking fabric, the required heald frame is 9 pages, the warp density remains the same, the total weft density is reduced by 18, and then design the 7-layer warp angle interlocking fabric, and finally input the pattern pattern in turn, the 8-layer weave Compared with the 9th floor pattern, one heald frame is used less, and a double warp will appear when the sutra is lifted. Compar...

Abstract

The invention belongs to the field of textile composites and particularly discloses a method for producing a same-width and different-thickness three-dimensional woven fabric on a general shuttleless loom. According to the method, the problem that the thickness of textile on the same fabric width can be variably designed under the condition that the machine is not stopped. The invention has the technical scheme that the weaving method comprises the following steps of: firstly, respectively designing a plurality of weave diagrams for the required textile thickness; secondly, sequentially sorting the weave diagrams and designing to change the weave diagram every a period of time; and then simultaneously lifting residual warp yarns on a heald frame and warp yarns of an adjacent system when the thickness of the textile is reduced by one layer. The subsequent operation is finished in the manner and textiles with variable thicknesses can be woven on the general shuttleless loom without stopping, and thus the production efficiency is increased. According to the weaving method disclosed by the invention, the field of products woven by the shuttleless loom is enlarged and the same-width and different-thickness fabrics suitably prepared from composite material are developed.

Description

technical field [0001] The invention relates to the field of textiles, in particular to a method for weaving three-dimensional woven fabrics. Background technique [0002] A lot of domestic research on three-dimensional fabrics began in the early 1990s. At present, three-dimensional knitted fabrics and three-dimensional braided fabrics are relatively mature. The research on three-dimensional woven fabrics is still relatively small. Three-dimensional woven fabric is a method of weaving fibers into three-dimensional fabrics with traditional looms. It is mainly produced by multi-layer warp weaving, and the fibers in the fabric are interpenetrated with each other. At present, various three-dimensional textile composite prefabricated parts can be woven. For example: three-dimensional orthogonal fabric, its isotropy is relatively good, the fabric woven with the same number of layers and the same thickness of yarn is relatively thick; the fabric with warp yarn passing through the...
