Description

Technical Field

[0001] The invention relates to the technical field of weaving machinery, and in particular to a double-layer three-dimensional fabric, an edge trimming method and a preparation method thereof, and a brush. Background Art

[0002] For three-dimensional fabrics, the main thing is the preparation of brushes. In the prior art, three-dimensional wool is generally woven onto the upper and lower layers of fabric to form a double-layer three-dimensional fabric with the upper and lower layers being fabrics and the middle being three-dimensional wool, that is, the double-layer three-dimensional fabric includes an upper fabric, a lower fabric and three-dimensional wool in the middle, and the two ends of the three-dimensional wool are woven into the upper fabric and the lower fabric respectively. After the double-layer three-dimensional fabric is woven, the three-dimensional wool of the double-layer three-dimensional fabric is cut to form a brush with the bottom plate being fabric and the fabric being three-dimensional wool. During the weaving process of the above-mentioned double-layer three-dimensional fabric, the upper and lower layers of fabric need to be trimmed. At present, the trimming method for double-layer three-dimensional fabrics on the market generally uses sock needles. When trimming with sock needles, it is necessary to introduce additional warp threads, and this part of the warp threads needs to be wound with a small disc head; because the number of warp yarns wound with the small disc head is different from the number of warp yarns wound with the large disc head, the tension of the large disc head and the small disc head is inconsistent, which will lead to the problem of trimming and hanging edges, and the high cost problem caused by the use of the small disc head.

[0062] Example 1: Preparation of double-layer three-dimensional fabric and brush

[0063] The double-layer three-dimensional fabric consists of an upper fabric, a lower fabric, and fluff fibers located between the upper fabric and the lower fabric. The fluff fibers are vertically interwoven with the upper fabric and the lower fabric; the net height of the fluff fibers is 5.5±0.2 mm.

[0064] The raw materials of the double-layer three-dimensional fabric are polyester filament and nylon filament. The specification of nylon filament is 850D / 120F, and the specification of polyester filament is 30s and 3 strands of base warp and 300D of weft.

[0065] Weaving steps: The warp yarn specifications of the upper and lower fabrics of the double-layer three-dimensional fabric are conventional polyester filaments, the weft yarn specifications of the upper and lower fabrics are conventional stranded polyester yarns, the warp yarn specifications of the middle layer of fluff fiber are 850 / 120 nylon filaments, and the weft density is 10 needles. The upper and lower fabrics are plain weaves, and the middle fluff fiber warp is woven using a U-shaped consolidation weaving process.

[0066] Edge finishing method: The threading of the twisted warp and the ground warp is based on Figure 11 is the twisted warp in the upper fabric, 2 is the ground warp in the upper fabric, 3 is the twisted warp in the lower fabric, and 4 is the ground warp in the lower fabric; two twisted heddles are used to trim the upper fabric and the lower fabric respectively, and the twisted heddles used in the upper fabric and the lower fabric are named: upper twisted heddles and lower twisted heddles respectively; the half heddles of the upper twisted heddles and the half heddles of the lower twisted heddles are paired, 1 is inserted into the threading hole of the half heddles of the upper twisted heddles, 2 is placed between the two base heddles of the upper twisted heddles and directly below the half heddles, and the weft yarn is introduced into the weft needle; 3 is inserted into the threading hole of the half heddles of the lower twisted heddles, 4 is placed between the two base heddles of the lower twisted heddles and directly below the half heddles, and the weft yarn is introduced into the weft needle; the base heddles of the upper and lower twisted heddles are respectively inserted into the heddles 1 and 2, and the heddles 1 and 2 are a group; the number of warp threads wound by the large pan head is 184. The weft yarn in the weft needle is introduced into the twisted heddles structure through the shed formed when the twisted heddles move. The double-layer three-dimensional fabric is woven on a multi-arm loom, and then the double-layer three-dimensional fabric is cut in layers to obtain the brush.

[0067] according to Figure 2 Drawing in the healds and reeds is performed, specifically, the first heald and the second heald are threaded with nylon filaments, and the remaining healds are threaded with polyester filaments; Figure 2 In the diagram of reed and heald drawing, all healds are 5-hole healds. Looking from the top to the bottom of the heald frame, the holes are numbered in sequence: hole ①, hole ②, hole ③, hole ④, hole ⑤; in the figure: "△" represents the upper warp, which passes through hole ① of frames 3-6; "×" represents the lower warp, which passes through hole ⑤ of frames 7-10; "▼" represents the gray yarn warp, which passes through hole ③ of frame 1; P1 represents passing through hole ③ of frame 1, and P2 represents passing through hole ③ of frame 2; two openings are formed by adjusting the height of the heald frame, and two weft needles are used for weft insertion, and the heald is used for edge finishing.

[0068] according to Figure 3 Set up the upper machine pattern card diagram, in the diagram: on page 3-8, the brown frame “■” indicates that the heald frame is lifted up, which is the warp tissue point; “□” indicates that the heald frame is lowered, which is the weft tissue point; on page 3-8, the brown frame “■” indicates that the heald frame is lifted up, which is the pile tissue point.

[0069] Figure 4 This is a picture of the edge before using the twisted heald structure. Figure 4 It can be seen that the edges are loose, the longitude and latitude lines float greatly, and are wavy. Figure 5 For the edge finishing pictures after using the heald, Figure 5 It can be seen that the edge is tight and the warp and weft are in a straight line. Compared with the edge picture before using the twisted heddle structure, after using the twisted heddle structure, the yarn tension of the wide edge of the fabric is more uniform and tighter. Figure 6 Comparison pictures of the webbing before and after the use of the twisted heald structure. The left side is the picture before the twisted heald structure is used, and the right side is the picture after the twisted heald structure is used. Figure 6It can be seen that before the twisted heald structure is used, the wide side is greater than 20mm and the tight side is about 8mm; after the twisted heald structure is used, the wide side is less than 20mm and the tight side is about 8mm; it can be seen that after adding the twisted heald, the width is reduced compared with the conventional one, which reflects the uniformity of the warp tension of the ribbon on another level.

[0070] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
