Description

Technical Field

[0001] The invention belongs to the technical field of textile fabrics, and in particular relates to a multi-warp hank weaving method, weaving equipment and a heald frame device. Background Art

[0002] Known as the Land of Silk, China boasts a long history of silk production and is renowned for the development and evolution of various fabric structures. Chinese textiles not only embody China's historical wisdom and culture, but also provide valuable resources for modern textile consumption and offer insights into the development of functional textiles.

[0003] Shirred is an ancient textile renowned for its soft, light, and breathable texture and high quality. Unlike the conventional cross-weave pattern of plain weave, the warp threads are twisted together in a series of figure-eight patterns, while the weft threads pass through the interstices created, creating a strong yet open mesh. This results in a stable, dimensional and structural design that resists deformation, laying the foundation for the durability of shirred garments. The open mesh provides porosity, allowing air and light to pass through the fabric more easily, resulting in a comfortable wearer.

[0004] Traditional leno fabrics typically feature two to four twisted warp threads. Leno fabrics can be categorized as either fixed-twist or loose-twist. In loose-twist leno fabrics, each warp thread is twisted with another, with four-warp lenos with loose-twist threads being the most complex. However, traditional leno weaving is typically performed by hand, relying on the individual weaver's skill. Most weaving methods and equipment have been lost.

[0005] Existing weaving equipment mainly includes a bracket, a single heald frame installed on the bracket, and a weft knife. Usually, a weaving equipment can only weave a single-structure hank, and the weaver needs to perform complex operations during the weaving process, resulting in slow weaving speed and low production efficiency.

The projections of the M healds on a plane parallel to the heald frames do not overlap, wherein N is a positive integer greater than or equal to 2, and M is a positive integer greater than or equal to N. The projections of the heald eyes of the M healds on a plane parallel to the heald frames are located on a straight line and can be arranged evenly. The projections of the M healds in the N heald frames on a plane equal to the heald frames do not overlap. The present invention can conveniently and flexibly weave a variety of woven fabrics with different organizational structures through the combination of N heald frames. The following example illustrates a heald frame device for weaving woven fabrics with different organizational structures.

[0134] Heald frame device embodiment 1

[0135] See also Figure 1 、 Figures 2A to 2D The heald frame assembly of this embodiment is used to weave a four-warp hank with no fixed hank group. The heald frame assembly includes four heald frames and eight healds 10. The four heald frames have the same structure and shape. The eight healds 10 have the same structure and can be needle-shaped healds with heald eyes. The height of the healds 10 is 1 / 3 to 2 / 3 of the height of the heald frame, and preferably, the height of the healds 10 is 1 / 2 of the height of the heald frame.

[0136] Along the front-to-back direction, the four heald frames are respectively named as a first heald frame 11 , a second heald frame 12 , a third heald frame 13 and a fourth heald frame 14 .

[0137] See also Figures 2A to 2D In this embodiment, the heald frame is rectangular and includes opposing top and bottom bars, as well as left and right bars connecting the top and bottom bars. Eight healds 10 are fixed to the bottom bars of the four heald frames, with two healds 10 fixed to the bottom bar of each heald frame, with the heald eyes of the healds 10 facing upward. Each heald frame and the healds 10 fixed thereto can be manufactured by cutting, die-casting, 3D printing, or other methods.

[0138] For the convenience of description, the bottom rods of each heald frame are marked in sequence from left to right starting from 1, that is, position 1, position 2... until position 8.

[0139] The first heald 10 in the first heald frame 11 is fixed at position 1 of the bottom bar, and the second heald 10 is fixed at position 5 of the bottom bar.

[0140] The first heald 10 in the second heald frame 12 is fixed at position 3 of the bottom bar, and the second heald 10 is fixed at position 7 of the bottom bar.

[0141] The first heald 10 in the third heald frame 13 is fixed at position 2 of the bottom bar, and the second heald 10 is fixed at position 6 of the bottom bar.

[0142] The first heald 10 in the fourth heald frame 14 is fixed at position 4 of the bottom bar, and the second heald 10 is fixed at position 8 of the bottom bar.

[0143] As can be seen from the fixed positions of the healds 10 described above, there is a gap of three positions between adjacent healds 10 on each heald frame. The projections of the eight healds 10 on a plane parallel to the heald frames, such as the first heald frame, do not overlap and are evenly arranged. The heald eyelets of the eight healds 10 are aligned in a straight line.

[0144] In the above description, two healds 10 are fixed on the bottom rod of each heald frame. In actual application, the length of the bottom rod of each heald frame can be extended from left to right to the required length, such as the designed width, so that more healds 10 can be added to the bottom rod. The number of added healds 10 can be a multiple of 8, and the arrangement on the bottom rod of each heald frame can be the same as the arrangement of the original 8 healds 10. In this case, the rib fabric woven using such a heald frame device has the same weave structure. On the other hand, the number of added healds may not be a multiple of 8, and the arrangement may be different from the original healds. In this case, the rib fabric woven using such a heald frame device has a different weave structure.

[0145] In this embodiment, a specific embodiment of the heald frame device is described by taking as an example an example in which the number of heald frames N is 4 and the number of healds M is 8 (M is twice N). In other embodiments, the number of heald frames N is not limited to 4, but may also be 3, 5, 6, etc., and the number of healds M may not be a multiple of the number of heald frames N. The specific design can be flexible according to the structure of the hank fabric.

[0146] See also Figure 1 Furthermore, the heald frame device of this embodiment also includes a transverse heald drawing device, a longitudinal heald lifting device and a guiding device.

[0147] The transverse heald drawing devices are respectively arranged on the left and right sides of the N heald frames, and are used to push and draw the heald frames in the left and right directions. Figure 1As shown, the transverse drawing device in this embodiment includes a plurality of draw ropes 21, one end of each of which is connected to the left rod and the right rod of the four heald frames respectively. In order to facilitate holding or fixing with the transverse driving device (not shown), the other end of each of the draw ropes 21 can be fixed with a stop block 22 respectively.

[0148] The longitudinal heald lifting devices are respectively arranged on the top side of the N heald frames, and are used to lift the heald frames in the up and down directions. Figure 1 As shown, the longitudinal heald lifting device in this embodiment includes multiple elastic suspension ropes 23, such as springs. One end of each of the elastic suspension ropes 23 is connected to the top rods of the four heald frames. For convenient gripping or securing to the longitudinal drive device (not shown), the other ends of the elastic suspension ropes 23 can be connected to a suspension rod 24. To prevent the heald frames from tilting during the lifting process, each heald frame's top rod can be connected to an elastic suspension rope 23 at each end. The other ends of these two elastic suspension ropes 23 are connected to the ends of the same suspension rod 24.

[0149] In some other embodiments, the longitudinal heald lifting devices can also be respectively arranged on the bottom sides of the N heald frames, or simultaneously arranged on the top and bottom sides of the N heald frames, which will not be illustrated here.

[0150] The heald frame device of the present invention can be driven manually, semi-automatically or fully automatically. In the absence of a transverse heald lifting device and a longitudinal heald lifting device, the heald frames can also be moved up and down or left and right by directly moving the heald frames.

[0151] The guide device is set on the left and right sides of the N-piece heald frame. Figure 1 As shown, the guide device in this embodiment includes two guide plates 25, which are symmetrically arranged on the left and right sides of the four heald frames. The guide plates 25 are provided with four guide slots 26 extending in the left-right direction. The left and right sides of the four heald frames, such as the left and right rods, are respectively accommodated in the guide slots 26. The guide plates 25 are provided with perforations corresponding to the guide slots 26 to allow the draw cords 21 in the transverse heald drawing device to pass through.

[0152] In this embodiment, the cross-section of the guide plate 25 can be L-shaped, but the present invention is not limited thereto. In other embodiments, the guide plate 25 can also be in other shapes, such as a flat plate. As long as a guide groove extending left and right can be set in it, the structure is feasible.

[0153] The guide device plays a guiding role in the movement process of the heald frame: when the suspension rod 24 above the top rod of a heald frame is pulled upward, the heald frame is driven to rise upward along the guide groove 26 through the elastic suspension rope 23 connected to the suspension rod 24; when the pull rope 21 on the left rod or right rod of a heald frame is pulled left or right, the heald frame moves left or right along the guide groove 26.

[0154] See also Figures 3A to 3D In this embodiment, the heald frame is an inverted U-shape, comprising a top bar and left and right bars connected to its ends. The healds 10 are secured to the top bar, with the heald eyes facing downward. The height of the heald frame is 0.4-1 times the height of the healds 10, preferably 0.5 times the height of the healds 10. With this heald frame shape, the height of the heald frame, namely the height of its left and right bars, can be relatively short.

[0155] use Figures 3A to 3D The other structures of the heald frame device of the heald frame shown may be the same as those of the heald frame device embodiment 1, and will not be described in detail here.

[0168] Heald frame device embodiment 5

[0169] like Figure 9B As shown, the difference between the heald frame device embodiment 5 and the heald frame device embodiment 1 mainly lies in the different arrangement positions of the healds on each heald frame. In detail:
