Problems solved by technology

[0008] Existing three-dimensional looms are difficult to form effective and clear openings when weaving satin fabrics, and it is more difficult to form openings on three-dimensional looms for weaving 2.5D satin fabrics with longer floating lengths. The problem of being able to efficiently weave 2.5D satin-like fabrics with complex structures

Embodiment

[0051] The structure of a three-dimensional fabric is determined by the interweaving relationship of the warp and weft yarns in the fabric, that is to say, during the fabric weaving process, the openings formed by lifting and lowering different warp yarn columns can weave fabrics of different structures. The shedding process described in this patent is to raise and lower different warp yarn rows under a specially arranged warp yarn group, and lift it twice to realize the shedding required for weaving 2.5D satin weave. Describe the weaving process of a kind of 4-layer 2.5D class satin weave fabric that the minimum number of cycles N is 8 in the embodiment, the fabric parameters are shown in Table 1, and this method is also applicable to the weaving of the 2.5D satin weave fabric that the minimum number of cycles N is N Weaving.

Abstract

The invention relates to a weaving method for a 2.5 D satin weave structural fabric. The method comprises the steps that warp is arranged on a multi-layer warp carrier of a three-dimensional loom on the basis of the rank rules, a three-dimensional loom opening device is modified, a special opening unit is designed and installed, particularly, a shedding sequence and an opening motion are designed on the basis of the warp and weft interweaving structural characteristics of a satin fabric, two-time lifting is performed on warp columns, all warp columns generate height differences, weft is introduced between two layers of warp in sequence, the weft is pushed into a weaving opening, and the fabric weaving is achieved. By adopting the technical scheme, weaving of the 2.5 satin weave structural fabric can be achieved. On the surface of the 2.5 D fabric, weaving points of warp and weft have the organizational structural characteristics of the plane satin fabric, the number of the weaving points of the weft and warp of the 2.5 D satin fabric is small, the better wettability, drapability and deformability are achieved, and the fabric used as an enhancing body can meet the requirement of a hook face thick wall composite material for the overall shape and performance of the fabric.

Description

technical field [0001] The invention relates to a three-dimensional fabric and its weaving technology, in particular to a weaving opening device and a weaving method for a 2.5D satin structure fabric. Background technique [0002] Three-dimensional fabric is an integral fiber network structure formed by interweaving continuous fiber bundles in space according to certain rules by using a unique three-dimensional textile processing method. As composite reinforcements, 3D fabrics provide the structural skeleton for composite members like a building's steel frame. Three-dimensional fabric is a preformed fabric with great development potential. It is composed of structural units repeated in two-dimensional or three-dimensional directions. In addition to strengthening the composite material structurally, it can also achieve near-net formation of the composite material. type. The earliest engineering application of 3D fabrics was in the field of carbon / carbon composites. In thei...
