Description

Technical Field

[0001] This utility model relates to a webbing, specifically a seamless spliced ​​perforated knitted webbing. Background Technology

[0002] Webbing is widely used in the textile industry and other daily life, especially in the clothing industry. Adjustable cords are widely used in sportswear, primarily for adjusting the tightness of the waistband. With the continuous development of the clothing industry, webbing has also evolved, with its technology and applications constantly being updated and iterated. Consumers are no longer just pursuing functionality, but also increasingly valuing aesthetics and innovative designs. Currently, there are two main types of perforated webbing on the market: 1. Fabric strips are sewn into a channel structure and then holes are punched in them. This process is complex, inefficient, and costly. The final product only shows the effect of the fabric covering, limiting the diversity of appearance and hindering the design of more diverse products; 2. ... Figure 1 As shown, the perforated knitted tape is made of two pieces of fabric A and B spliced ​​together, with a splice mark 1 on the surface. During use, when the tape is stretched with the adjustment cord, the holes are prone to deformation and tearing. There is a risk of exposed thread at the splice, and there is a clear splice mark. The surface of the tape is uneven and not visually appealing.

[0003] Most of the perforated tapes commonly found in the clothing market are woven from the two structures mentioned above. As a result, they suffer from limited variety in appearance, low production efficiency and high cost, unstable quality, and lack of visual appeal, making it difficult to meet the increasingly high consumption demands of consumers. Summary of the Invention

[0004] To address the aforementioned technical problems, this invention provides a seamless splicing perforated knitted tape.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: A seamless, perforated knitted tape includes a tape body comprising holes, a surface layer, a root yarn layer, and a bottom layer. The root yarn layer is located between the surface layer and the bottom layer and serves to connect the two layers. At least two holes are provided and spaced apart, with the holes sequentially penetrating the surface layer, the root yarn layer, and the bottom layer. The surface layer has a hole spacing area and a hole parallel area. The hole spacing area is located between adjacent holes, and the hole parallel area is located above and below the holes. The hole spacing area and the hole parallel area are completely traversed by the weft yarn of the surface layer in one go, thereby forming a tape body with a seamless surface layer.

[0006] As a further improvement, the hole spacing area includes a small hole spacing area and a large hole spacing area. The small hole spacing area is the region where the ends of two holes that are close to each other face the middle of the webbing body, and the large hole spacing area is the region where the ends of two holes that are far apart face the edge of the webbing body.

[0007] As a further improvement, the hole parallel region includes an upper parallel region and a lower parallel region, the upper parallel region being the area above the hole and the lower parallel region being the area below the hole.

[0008] As a further improvement, the root yarn layer is formed by lateral yarn movement, and the root yarn layer is woven with elastic yarn.

[0009] As a further improvement, the surface layer includes an upper layer, a middle layer, and a lower layer that are distributed in an overlapping manner; the lower layer is woven across the entire area after passing through the hole spacing area along a single needle yarn to the upper parallel area of ​​the hole, and also woven across the entire area after passing through the hole spacing area along a single needle yarn to the lower parallel area of ​​the hole; the weft yarns of the middle layer all cross the hole spacing area and the upper parallel area of ​​the hole, and the weft yarns of the upper layer all cross the hole spacing area and the lower parallel area of ​​the hole.

[0010] As a further improvement, the bottom layer and the top layer of the webbing body have the same organizational structure; or the bottom layer is formed by splicing two pieces of fabric together.

[0011] As a further improvement, the hole is located in the middle, slightly above the middle, or slightly below the middle of the main body of the webbing.

[0012] As a further improvement, the parallel areas of the holes are provided with patterns, meshes, or jacquard.

[0013] As a further improvement, the main body of the webbing is made of polyester fiber, polyamide fiber, polyurethane fiber or cotton.

[0014] As a further improvement, the main body of the webbing is either non-elastic webbing or elastic webbing.

[0015] This utility model has the following beneficial technical effects: By using a fully transverse weft yarn structure, the surface of the belt is seamless, resulting in a smoother surface that is less prone to showing white areas and is more visually appealing. This also mitigates the risk of deformation and tearing of the holes after the adjustment cord is stretched. Furthermore, the multi-layered surface structure ensures consistent thickness.

Thus, features defined with "first" and "second" may explicitly or implicitly include one or more of the stated features.

[0019] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection. They can refer to a mechanical connection or an electrical connection. They can refer to a direct connection or an indirect connection through an intermediate medium, and they can refer to the internal communication of two components or the interaction between two components. For those skilled in the art, the specific meaning of the above terms in this invention can be understood according to the specific circumstances.

[0020] Example 1 like Figure 2As shown, a seamless, perforated knitted tape includes a main body, comprising holes 4, a surface layer 1, a root yarn layer 2, and a bottom layer 3. The root yarn layer 2 is located between the surface layer 1 and the bottom layer 3 and serves to connect them. Two holes 4 are provided and spaced apart, penetrating the surface layer 1, root yarn layer 2, and bottom layer 3 sequentially. The surface layer 1 has a hole spacing area and a hole parallel area. The hole spacing area is located between the two holes, and the hole parallel area is located above and below the holes. The hole spacing area and the hole parallel area are formed by the weft yarn of the surface layer crossing the entire area at once, thus forming a seamless tape body with a seamless surface layer. By having the weft yarn of the surface layer cross a certain number of stitches, the problem of visible seams when two pieces of fabric are joined is solved.

[0021] The top and bottom layers are planar layers and can be designed as solid structures.

[0022] The hole spacing zone refers to the transition area formed by continuous weft knitting between adjacent holes. This can be achieved by adjusting the needle density and is used to disperse stress concentration around the holes. The hole parallel zone refers to the extended areas on the upper and lower sides of the holes that are parallel to the hole axis. This can be formed by arranging parallel weft yarns and is used to maintain the flatness of the tape surface. The root yarn layer connects the surface layer and the bottom layer through yarn lateral movement. This can be achieved by using elastic yarns to enhance the interlayer bonding strength. A single weft yarn crossing refers to the same weft yarn passing through both the hole spacing zone and the parallel zone simultaneously. This can be achieved using a double-needle bed knitting machine and is used to eliminate surface layer splicing marks.

[0023] Specifically, during the weaving process, the surface weft yarns run continuously between the hole spacing area and the parallel area, avoiding the yarn breakage or splicing operations required in traditional processes. The root layer uses elastic yarns that run laterally through the surface and bottom layers, forming a reinforced structure in the hole penetration area. The spacing area between adjacent holes maintains uniform tension of the tape by adjusting the weft yarn density, while the parallel areas above and below the holes maintain the integrity of the tape surface through continuous weft yarn extension. This structure allows the hole area to form a seamless connection with the surrounding fabric, avoiding weak points in strength caused by splicing.

[0024] Example 2 refer to Figure 2-6 As shown, the hole spacing area includes a small hole spacing area 51 and a large hole spacing area 52. The small hole spacing area 51 is the region where the ends of two holes 4 that are close to each other face towards the center of the webbing body, and the large hole spacing area 52 is the region where the ends of two holes 4 that are far apart face towards the edge of the webbing body. In other words, the small hole spacing area is the region near the center line of the webbing body, and the large hole spacing area is the region near the two side edges of the webbing body. The length of the large hole spacing area depends on the required webbing length, and the small hole spacing depends on the length between the two cords, generally 30-40 mm is optimal.

[0025] refer to Figure 2 The main body of the webbing is longitudinal in length and transverse in width. The parallel area of ​​the hole includes an upper parallel area 61 and a lower parallel area 62. The upper parallel area 61 is the area above the hole 4, and the lower parallel area 62 is the area below the hole 4.

[0026] The surface layer 1 comprises an upper layer 13, a middle layer 12, and a lower layer 11, which are distributed in an overlapping manner. The lower layer 11 is woven across the entire area after passing through the hole spacing area along a single yarn to the upper parallel area of ​​the hole, and also across the entire area after passing through the hole spacing area along a single yarn to the lower parallel area of ​​the hole. The weft yarns of the middle layer all cross the hole spacing area and the upper parallel area of ​​the hole, and the weft yarns of the upper layer all cross the hole spacing area and the lower parallel area of ​​the hole. By setting the surface layer as three layers and weaving them according to a specific cross-layout pattern, the thickness of the surface layer after weaving is ensured to be consistent.

[0027] Specifically, the lower layer 11 first transitions along a single needle yarn from the large-spacing area 52 and the small-spacing area 51 to the upper parallel area 61 of the holes before crossing it completely; the lower parallel area 62 of the holes is similarly transitioned along a single needle yarn from the large-spacing area 52 and the small-spacing area 51 to the lower parallel area 62 of the holes before crossing it completely; the middle layer crosses the large-spacing area, the small-spacing area, and the upper parallel area of ​​the holes completely; the upper layer crosses the large-spacing area, the small-spacing area, and the lower parallel area of ​​the holes completely. Through the three overlapping layers, a perforated knitted tape with no splicing marks and uniform thickness is achieved.

[0028] The continuous cross-weaving of the lower layer between the perforation spacing area and the perforation parallel area ensures uniform yarn distribution around the perforations, avoiding surface unevenness caused by localized yarn density differences. The weft yarns of the middle layer cover the perforation spacing area and the upper parallel area of ​​the perforations, weaving to form a stable mesh structure and preventing deformation of the perforation edges due to stretching. The weft yarns of the upper layer cover the perforation spacing area and the lower parallel area of ​​the perforations, forming an alternating weaving path with the lower layer, further eliminating seam marks on the surface. The three woven layers interweave with each other through yarn extension paths in different directions, ultimately forming a seamless, integrated structure.

[0029] The entire span is used at the junction of the hole spacing area and the hole, which to some extent improves the risk of deformation and tearing of the holes after the rope is stretched.

[0030] The bottom layer can be formed by the same weave as the top layer, that is, by multiple bottom layers spanning across, or by splicing together multiple pieces of fabric. The splicing method will leave traces, but the bottom layer will not be visible because it is covered by the top layer. The splicing method can reduce the use of combs.

[0031] The root yarn layer is formed by a small number of stitches, such as 1 stitch, with the yarn shifting laterally. The root yarn layer is woven with elastic yarn.

[0032] The holes are located in the middle, slightly above the middle, or slightly below the middle of the main body of the webbing. In addition to two holes, more can be added. By adjusting the hole positions, the visual balance of the holes can be adjusted according to different garment design needs. For example, a central position is suitable for symmetrical belt structures, while slightly above or below the middle is suitable for functional garments that require concealing the holes.

[0033] Example 3 The parallel areas of the holes are decorated with patterns, meshes, or jacquard to enhance their decorative appeal.

[0034] Patterns refer to visual designs created through the arrangement or weave variations of colored yarns. These can be achieved using a jacquard loom or alternating weaves of two-color yarns, and include elements such as letters, geometric shapes, or gradient textures. Mesh refers to an open structure formed by sparse weft yarns. This can be achieved by reducing weft density or using skip-stitch weaving techniques, creating honeycomb or striped breathable areas. Jacquard refers to three-dimensional patterns created through variations in the texture of different weave structures. This can be achieved using float weaving or localized thickening techniques, creating effects such as embossed designs or imitation embroidery textures.

[0035] While ensuring the structural stability of the perforated tape, the area around the holes can accommodate diverse design elements. Pattern design can enhance product recognition, mesh structure can improve breathability, and jacquard texture can increase surface texture. All three can be completed simultaneously through the weaving process without the need for subsequent processing.

[0036] The main body of the webbing is made of polyester fiber, polyamide fiber, polyurethane fiber or cotton.

[0037] Polyester fiber refers to synthetic fibers made of polyethylene terephthalate, specifically polyester filament or staple yarn, which are characterized by high abrasion resistance and controllable cost. Polyamide fiber refers to synthetic fibers composed of nylon materials, specifically nylon 6 or nylon 66 yarn, which have high breaking strength and resistance to deformation. Polyurethane fiber refers to elastic fibers containing urethane segments, specifically spandex core-spun yarn or bare spandex yarn, which impart elastic recovery properties to the weave body. Cotton refers to natural plant fibers, specifically combed cotton or carded cotton yarn, which have moisture-wicking and breathable properties.

[0038] The main body of the webbing can be either non-elastic or elastic. Non-elastic webbing refers to webbing woven from low-elasticity or non-elastic fibers, specifically polyester or cotton fibers using plain or twill weaving techniques. Its structure is dense and not easily deformed, making it suitable for scenarios requiring a fixed shape or withstanding significant tensile force. Elastic webbing refers to webbing woven from elastic yarns, specifically polyurethane fibers or elastic composite yarns using knitting techniques. It can stretch and recover its original shape within a certain range, making it suitable for scenarios requiring dynamic adjustment or conforming to curved surfaces.

[0039] Example 3 This example demonstrates a planar structure where the bottom layer uses a spliced ​​construction, the top layer uses a seamless construction, and the weft weft pad shifts laterally by ≥2 needle positions with ≥2 cycles (the longitudinal direction of the webbing is the cycle direction). Figure 4 As shown, the right side of the bottom weft weave structure forms a planar structure F1 by shifting 13 needle positions laterally, the left side of the bottom weft weave structure forms a planar structure by shifting 13 needle positions laterally, and then forms a perforated area F2 according to the process cycle length. The left side of the bottom weft weave structure forms a perforated spacing area F3 by shifting 14 needle positions laterally and according to the cycle length.

[0040] refer to Figure 5 and 6 In the outer layer, the bottom layer is formed into perforated areas F4 and F7 on both sides by shifting 13 needle positions laterally and according to the cycle length. Then, transitional perforated areas F5 and F6 are formed on both sides by shifting 1 needle position laterally and according to the cycle length. The preferred yarn padding number for the transitional areas is 1-1-2-2. The middle and top layers are formed into perforated areas F8 and F10 on both sides by shifting 13 needle positions laterally and according to the cycle length. Then, the perforation spacing area F9 is formed on both sides by shifting 26 needle positions laterally and according to the cycle length. The preferred materials are PA6 and PES. The core layer can be located between the bottom and outer layers, and shifting 1 needle position laterally gives the webbing good elasticity. Combining the overlapping and covering processes of the bottom and outer layers creates a seamless perforated knitted webbing with a smooth surface that is less prone to showing white areas and has a more aesthetically pleasing appearance.

[0041] refer to Figure 7 It can be applied to trousers, or clothing, underwear and other garments.

[0042] It should be noted that the above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. However, any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
