Embodiment Construction

[0056] like figure 2 As shown, the present invention uses the three-position double shed opening of the warp yarn and the double weft insertion layer by layer as the means, and by changing the warp passing mode and the law of shedding and weft insertion, the maximum distance H between the uppermost warp yarn and the lowermost warp yarn when shedding is ′=2h+t<

[0057] Orthogonal fabric warp threading method is attached image 3 As shown, there are multi-layer three-dimensional fabric 2, reed 3, heddle 4, warp yarn 5 as shown in the figure. The heddle 4 is provided with a heald eye. The numbers of the heddles are arranged as Z1, Zn+1, Z2, Z3...Zn-1, Zn, which are respectively used to drive the warp yarns 1, n+1, 2, 3,...n-1 arranged in sequence from top to bottom , n. The warp yarn 5 is divided into a binding yarn and a lining warp yarn. The binding yarn is a warp yarn conne...

Abstract

The invention provides a weaving method of a multilayer three-dimensional fabric. By opening and guiding wefts layer by layer, the warp drafting manner and opening and weft guiding rules are changed, the problem that the multilayer fabric reed height and the beating up stoke are excessive large is solved, the maximum distance between the top layer of warps and the bottom layer of warps is shortened during opening, strict limits of layers of the fabric are avoided, the layers of the fabric is increased as several times of the original, wear times between warps and harness wires and between warps are reduced, warp breakage rate is decreased, and operating efficiency of a spinner and fabric quality are improved.

Description

technical field [0001] The invention relates to the textile field of three-dimensional fabrics, in particular to a weaving method of multi-layer three-dimensional three-dimensional fabrics. Background technique [0002] With light weight, high strength, high modulus, high temperature resistance and other excellent properties, it is widely used in the field of aviation and aerospace carbon fiber composite materials, and its skeleton structure material is carbon fiber multi-layer three-dimensional fabric. At present, multi-layer three-dimensional three-dimensional fabrics are mostly woven by opening n sheds at the same time and inserting n wefts at the same time. This method is limited in the number of weaving layers. like figure 1 As shown, t is the fabric thickness (1-30mm), n is the number of layers (1-30 layers), h is the single shed height (about 50mm), because the distance H′ between the uppermost layer and the lowermost warp yarn is n times the height h of a single sh...
