Description

Technical Field

[0001] This invention belongs to the field of textile technology, specifically a one-piece molded double-buffered webbing. Background Technology

[0002] As society continues to develop and progress, consumers' aesthetic preferences and pursuits regarding clothing are also constantly changing and improving, with a greater emphasis on the wearing effects brought about by innovation. As an essential accessory for clothing, webbing is facing increasingly diverse functional demands from consumers. However, existing webbing, after being deformed through warp arrangement, often struggles to return to its original shape, exhibiting poor resilience.

[0003] In addition, some webbing currently has a cushioning function, such as patent CN223329468U, which discloses a cushioning webbing. This webbing body is woven integrally with warp and weft threads. The webbing body includes an integrally woven weft elastic layer, a cushioning layer, and a covering layer. The weft elastic layer has a weft retraction function. The edge of the covering layer is connected to the weft elastic layer. The cushioning layer is sandwiched between the weft elastic layer and the covering layer. The weft elastic layer pulls back the cushioning layer and the covering layer in the weft direction, causing the cushioning layer and the covering layer to contract and form an arch, providing a certain degree of cushioning performance when compressed. However, it is a single-layer cushioning structure, and its cushioning effect is relatively limited. Summary of the Invention

[0004] To address the aforementioned technical problems, the present invention provides an integrally molded double-buffered webbing.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0006] An integrally formed double-buffered webbing includes a webbing body. The webbing body is formed by interlacing warp and weft yarns through a double-weft structure to form an upper double-warp structure layer and a lower double-warp structure layer. The upper double-warp structure layer includes an upper surface layer, an upper buffer layer, and an upper skeleton layer connected from top to bottom. The lower double-warp structure layer includes a lower skeleton layer, a lower buffer layer, and a lower surface layer connected from top to bottom. The upper skeleton layer and the lower skeleton layer are interlaced with synchronously interlaced weft yarns to form a central skeleton layer. The upper buffer layer is located above the central skeleton layer and the lower buffer layer is located below the central skeleton layer, forming a double-buffered structure.

[0007] As a further improvement, both the upper and lower buffer layers have an uneven structure.

[0008] As a further improvement, the warp yarns of the upper and lower buffer layers exist in the form of free yarns; or are partially or completely interwoven on their respective adjacent surfaces in the form of pile floats, with a float length ≥ 5 wefts.

[0009] As a further improvement, the warp yarns of the upper and lower surface layers are made of fine denier elastic core-spun yarn, which includes a core yarn and a cover yarn, wherein the core yarn is selected from 40D to 140D; and the cover yarn is selected from 40D to 140D with DPF ≤ 1.2.

[0010] As a further improvement, both the upper and lower buffer layers are made of 70D~600D high-loft elastic yarn.

[0011] As a further improvement, both the upper and lower skeleton layers are made of 140D-1680D elastic core-spun yarn.

[0012] As a further improvement, the upper surface layer and / or the lower surface are provided with a jacquard layer.

[0013] As a further improvement, both the upper and lower buffer layers are either a continuous, integral structure or a segmented structure.

[0014] As a further improvement, the upper and lower skeleton layers contain elastic yarns.

[0015] As a further improvement, the upper buffer layer and the lower buffer layer are provided with at least one layer.

[0016] The present invention has the following beneficial technical effects:

[0017] A dual-layer structure with upper and lower warp threads forms a double-buffered system, significantly improving impact absorption performance. The upper and lower surface layers, combined with the intermediate buffer layer, achieve flexible contact on both sides and uniform pressure distribution, enhancing wearing comfort. A co-weft interlacing technique fuses the two skeleton layers to form a central skeleton layer, maintaining structural integrity while optimizing mechanical properties. The symmetrical upper and lower structure enables a reversible design, expanding the product's applicability. Integrating the buffer layer and skeleton layer into a single unit achieves weight reduction and volume compression while maintaining the same level of protection.

[0018] By integrating the cushioning layer and the skeleton layer into a single molding process using a three-dimensional weaving technique, a double cushioning effect can be achieved without subsequent processing, enriching the usability of the webbing. It can be widely used in shoulder straps, armbands, necklines, back straps, and other fields. Attached Figure Description

[0027] like Figures 1-5As shown, an integrally formed double-buffered webbing includes a webbing body. The webbing body is formed by the interlacing of warp and weft yarns through a double-weft structure, forming an upper warp double structure layer A and a lower warp double structure layer B. The upper warp double structure layer A includes an upper surface layer A1, an upper buffer layer A2, and an upper skeleton layer A3 connected from top to bottom. The lower warp double structure layer B includes a lower skeleton layer B1, a lower buffer layer B2, and a lower surface layer B3 connected from top to bottom. The upper skeleton layer A3 and the lower skeleton layer B1 are interlaced with synchronously interlaced weft yarns to form a central skeleton layer C. The upper buffer layer A2 is located above the central skeleton layer C, and the lower buffer layer B2 is located below the central skeleton layer C, forming a double-buffered structure.

[0028] Warp double weave is a fabric structure composed of two warp yarn systems (outer warp and inner warp) interwoven with a single weft yarn system, exhibiting a warp-face effect on both sides. The outer warp and weft yarns form the outer layer structure, while the inner warp and weft yarns form the inner layer structure. The overlapping of the two achieves the effect of the outer layer covering the inner layer.

[0029] Both the upper buffer layer A2 and the lower buffer layer B2 have an uneven structure, and can be woven into a wavy structure for better cushioning.

[0030] The specific weaving process is as follows:

[0031] The upper warp double structure layer A and the lower warp double structure layer B are formed by interlacing warp yarns JA1, JA2, JA3, JB1, JB2, and JB3 with weft yarns WA and WB through a double weft structure. The upper surface layer A1 and the lower surface layer B3 form a comfortable and delicate layer that fits snugly against the skin. The lower skeleton layer A3 of the upper warp double structure layer A and the skeleton layer B1 of the lower warp double structure layer B are arranged adjacent to each other. Based on the characteristics of the double warp structure, the weft yarn WA of the upper warp double structure layer A is divided into two groups of weft yarns, WA1 and WA2, after interlacing with the warp yarns of the upper warp double structure layer A. Similarly, the weft yarn WB of the lower warp double structure layer B is divided into two groups of weft yarns, WB1 and WB2, after interlacing with the warp yarns of the lower warp double structure layer B. The upper surface layer A1 of the upper warp double structure layer A is formed by interlacing warp yarns JAI and weft yarns WA1. The buffer layer A2 is formed by filling the space between the upper surface layer A1 and the upper skeleton layer A3 with warp yarns JA2 in a non-interlaced state according to the characteristics of the double warp structure.

[0032] The lower skeleton layer A3 is formed by the interlacing of warp yarns JA3 and weft yarns WA2; the lower double warp structure layer B is configured in the opposite direction, with the upper surface being the lower skeleton layer B1, which is formed by the interlacing of warp yarns JB1 and weft yarns WB1. The buffer layer B2 is formed by filling the space between the lower skeleton layer B1 and the lower surface layer B3 with warp yarns JB2 in a non-interlaced state, according to the characteristics of the double warp structure, thus forming the intermediate warp-filled buffer layer B2. The lower surface layer B3 is formed by the interlacing of warp yarns JB3 and weft yarns WB2. Based on the principle of the double warp structure, the warp yarns of the upper skeleton layer A3 of the upper double warp structure layer A and the lower skeleton layer B1 of the lower double warp structure layer B simultaneously move in a 2-center, 1-up, 1-down pattern. During this 1-up, 1-down movement, due to the synchronous up-and-down motion, the warp yarns JA3 of skeleton layer A3 and JB1 of skeleton layer B1 lock the lower weft yarns WA2 of the upper double warp structure layer A and the upper weft yarns WB1 of the lower double warp structure layer B in the middle, forming an elastic central skeleton layer C.

[0033] Example 2

[0034] refer to Figures 1-4 As shown, the warp yarns of the upper and lower buffer layers exist in the form of free yarns; or are partially or completely interwoven on their respective adjacent surfaces in the form of pile floats, with a float length of ≥5 wefts, in the form of free yarns or pile floats to ensure good buffering performance.

[0035] The warp yarns of the upper and lower surface layers are made of fine denier elastic core-spun yarn, which includes a core yarn and a cover yarn. The core yarn is selected from 40D to 140D, and the cover yarn is selected from 40D to 140D with a DPF ≤ 1.2. Through the elastic core-spun yarn, the upper surface layer A1 and the lower surface layer B3 are formed into a delicate layer that can be used as a skin-friendly layer. This ensures skin-friendly comfort while achieving a synergistic match with the elastic recovery performance of the intermediate skeleton layer.

[0036] Both the upper and lower buffer layers are made of 70D~600D high-loft elastic yarn, preferably DTY elastic yarn. At least one upper and lower buffer layer is provided; multiple layers can be stacked together.

[0037] Both the upper and lower skeleton layers are made of 140D-1680D elastic core-spun yarn, with different specifications selected depending on the product category.

[0038] The upper and / or lower surfaces are provided with jacquard layers to form a decorative effect.

[0039] Both the upper and lower buffer layers are either a continuous, integral structure or a segmented structure.

[0040] Example 3

[0041] like Figures 1-5 As shown, it is produced using a computerized shuttle loom.

[0042] 1. Preparation of the wrapping root

[0043] Double wrapping is achieved using 560D spandex and 40D / 1 SD nylon, with the core layer being 560D spandex and the cover yarn being 40D / 1 nylon, forming a wrapping layer Y5604 / 30. Alternatively, the warp core layer is 70D spandex and the cover yarn is 40D / 1 nylon, forming a wrapping layer Y70V1 / 30.

[0044] 2. Preparation for Warping

[0045] The warp yarns used for the ribbon are sorted and wound onto warp beams for pre-weaving preparation. The warp yarns consist of 378 yarns: 70D / 2 nylon, 40D / 2 nylon, Y70V7 / 30 core-spun yarn, and Y5604 / 30 base-spun yarn. Of these, 52 are skeleton yarns and 326 are body yarns. All warp yarns are warped and prepared into a warp head.

[0046] 3. Wear brown

[0047] according to Figure 3 The warp yarns are arranged in the order shown in the diagram, so that all the warp yarns pass through the palm fiber holes. Figure 3 The small squares in the shaded area, "142, 141, 140…", represent the serial numbers of the computer's brown wire mesh. Figure 3 The numbers "1, 2, 3..." in the small and medium squares represent the brown frame sequence number; the numbers "↑1↑2↑3↑..." in the arrow squares represent the order in which the warp yarns enter the reed.

[0048] 4. Production density

[0049] The fabric density in this embodiment is 18.2 needles / cm.

[0050] 5. Width and reed

[0051] In this embodiment, the width is 17 mm, the reed specification is 30 (30 squares per inch), and a total of 25 squares are used. Figure 3 The reed insertion sequence shown in the diagram involves inserting the warp yarns into the designated grid positions on the reed.

[0052] 6. Weft yarn

[0053] In this embodiment, the weft yarn is one 40D / 1 nylon yarn on the top and one on the bottom.

[0054] 7. Trim

[0055] In this embodiment, the edge yarn is a single piece of 40D / 1 nylon.

[0056] 8. Laws of Movement in Organizational Structure

[0057] like Figure 4 As shown in the diagram, the tissue structure of this example is arranged according to the floral chain. Boxes 1, 2, 3, 4, 5, and 6 represent the skin-friendly comfort layer structure, with a tissue structure of 3 upper and 1 middle layer and 3 lower and 1 middle layer. The shaded area represents computer-controlled browning.

[0058] 9. The 40D / 1 weft yarn passes through the weft yarn conveyor, passing one weft yarn above and one below the weft hook, and the weft hook drives...

[0059] After the weft yarn passes through the opening formed by the warp yarn driven by the hard palm fiber chain, the edge yarn driven by the edge hook passes through the weft yarn from top to bottom, and is collected by the latch needle. The reed swings back and forth to secure the weft yarn that has passed through the opening.

[0060] 10. The rubber roller, driven by the density adjustment device, pulls the warp yarns after beveling to form a webbing.
