Description

Technical Field

[0001] This utility model relates to the field of knitted fabrics, specifically to jacquard fabrics with gradually varying loop widths or thicknesses, as well as shoe uppers, curtains, and tops. Background Technology

[0002] Knitted fabrics are commonly used in shoe uppers, clothing, home textiles, and backpacks. With societal progress and rising living standards, the demands for breathability, comfort, and functionality in textile products are increasing. This is especially true for plain weave fabrics. Plain weave is the basic structure of plain weave fabrics, characterized by alternating warp and weft yarns, numerous interlacing points, and a tightly packed yarn arrangement. This tight structure results in small pores within the fabric, hindering rapid air exchange between the inside and outside, thus leading to poor breathability in plain weave fabrics. Therefore, further research and exploration are needed in this area.

[0003] In view of this, the applicant has conducted in-depth research on the above-mentioned issues, which led to this case. Utility Model Content

[0045] To make the objectives, technical solutions, and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this utility model.

[0046] Example 1

[0047] like Figures 1-2 As shown, this embodiment provides a jacquard fabric with gradually varying loop width or thickness. The jacquard fabric includes a fully knitted top layer 1, a spaced-knitted bottom layer 3, and an intermediate layer for connecting the top layer 1 and the bottom layer 3. The bottom layer 3 has a plurality of spaced-knit grooves 4. In this embodiment, each spaced-knit groove 4 is strip-shaped.

[0048] A first coil strip A is formed on the surface layer 1, a first coil is formed inside the first coil strip A, and a breathable gap is formed in the space enclosed by the first coil strip A. The breathable gap inside the first coil strip A is connected to at least one needle groove 4.

[0049] It should be noted that the length direction of the first coil strip A can be the same as the length direction of the needle spacer groove 4, or the length direction of the first coil strip A can form an angle with the length direction of the needle spacer groove 4.

[0050] The first coil bar A includes at least one gradient segment, the width of which gradually changes from one end to the other and / or the thickness of which gradually changes from one end to the other. The change here refers to the change in the width of adjacent first coils. For example, the change here can be first increasing and then decreasing, or first decreasing and then increasing, or first increasing and then decreasing and then increasing, or first decreasing and then increasing and then decreasing.

[0051] Furthermore, the surface layer 1 also has a second coil strip B, which is arranged alternately with the first coil strip A, forming a raised strip texture.

[0052] It should be noted that the first loop strip A can be jacquard together with the second loop strip B to form the texture of the jacquard fabric; the first loop strip A can also be in the form of a line to form the texture of the jacquard fabric on its own; or the first loop strip A can also be in the form of a block to form the regional jacquard texture of the jacquard fabric.

[0053] Preferably, the outline of the first coil bar A is circular or elliptical.

[0054] The structure of the needle groove 4 formed by the bottom 3 needles, combined with the breathable gap of the first loop strip A, makes the air permeability of the jacquard fabric 20%-40% higher than that of plain weave fabric, and the air permeability of the jacquard fabric is relatively good.

[0055] Preferably, the jacquard fabric has several full-permeable holes and / or several semi-permeable holes. The presence of full-permeable and semi-permeable holes improves the breathability of the jacquard fabric. It should be noted that full-permeable holes refer to through-holes that penetrate the jacquard fabric, while semi-permeable holes refer to blind holes that do not penetrate the fabric. Full-permeable and semi-permeable holes can be formed using existing conventional weaving techniques, which will not be elaborated further.

[0056] The surface layer 1 includes the face yarn, the bottom layer 3 includes the bottom yarn, the middle layer includes the middle yarn, the first coil strip A includes the first yarn, and the second coil strip B includes the second yarn.

[0057] Preferably, the first yarn is connected to the bottom layer 3 and interwoven with the bottom yarn.

[0058] Preferably, the fineness of the first yarn is greater than that of the second yarn, so that the texture formed by the jacquard of the first loop strip A and the second loop strip B together is more three-dimensional, creating a difference in visual and tactile sensation.

[0059] Preferably, the first yarn is one or at least two of the following: quick-drying absorbent yarn, water-repellent yarn, high-strength yarn, PU-coated yarn, and elastic yarn. These yarns are all conventional blended yarns. When the first yarn is a quick-drying absorbent yarn, the moisture-wicking and quick-drying properties of the first loop A are enhanced, which is beneficial for perspiration wicking. When the first yarn is a water-repellent yarn, the waterproofness of the first loop A is enhanced. When the first yarn is a high-strength yarn, the strength and durability of the first loop A are improved. When the first yarn is a PU-coated yarn, after high-temperature setting, the PU on the surface of the first yarn melts, making the structure of the area where the first loop A is located more stable, resulting in a stronger integrated support effect in that area. It should be noted that when the first yarn is at least two of the following: quick-drying absorbent yarn, water-repellent yarn, high-strength yarn, PU-coated yarn, and elastic yarn, the first yarn is essentially a composite yarn.

[0060] Preferably, the first yarn is one or at least two of polyester, nylon, PU, ​​hot melt yarn, and animal or plant fibers. It should be noted that when the first yarn is at least two of polyester, nylon, PU, ​​hot melt yarn, and animal or plant fibers, the first yarn is essentially a composite yarn.

[0061] like Figures 1-3 As shown, this embodiment also provides a method for manufacturing jacquard fabric with gradually varying loop width or thickness (i.e., the method for manufacturing the jacquard fabric described above). The method involves using a weft knitting machine to knit the fabric to obtain a greige fabric. This weft knitting machine has at least four loop-forming systems, namely, the first loop (L1), the second loop (L2), the third loop (L3), and the fourth loop (L4). The weft knitting machine also has a cylinder and a needle plate. In this embodiment, the weft knitting machine is a 14-gauge, 20-inch circular knitting machine with a jacquard device and a transfer function, featuring an 8-way knitting and 4-way transfer configuration. It should be noted that the weft knitting machine can also be a conventional circular knitting machine or a flat knitting machine with a jacquard device.

[0062] The fabric includes a full-needle knitted surface layer 1, a spaced-needle knitted bottom layer 3, and an intermediate layer for connecting the surface layer 1 and the bottom layer 3. The surface layer 1 has a first loop strip A and a second loop strip B. The second loop strip B is staggered from the first loop strip A. The surface layer 1 includes a face yarn, the bottom layer 3 includes a base yarn, the intermediate layer includes an intermediate yarn, the first loop strip A includes a first yarn, and the second loop strip B includes a second yarn.

[0063] The intermediate yarn can be made of conventional yarn. In this embodiment, the fineness of the intermediate yarn is 150D.

[0064] The veil can be made of conventional yarn. In this embodiment, the veil includes 300D polyester yarn and hot melt yarn.

[0065] The base yarn can be a conventional yarn. In this embodiment, 40D / 100D×3 core-spun yarn is used as the base yarn for weaving. Here, 40D / 100D×3 means that the core yarn is a 40D spandex yarn and the outer covering yarn is a 100D single yarn, which are combined to form a 40D / 100D covering yarn. Then, the three 40D / 100D covering yarns are fed into the weaving together.

[0066] Preferably, the first yarn is one or at least two of polyester, nylon, PU, ​​hot melt yarn, and animal or plant fibers.

[0067] Preferably, the first yarn is one or at least two of the following: absorbent and quick-drying yarn, water-repellent yarn, high-strength yarn, and PU-coated yarn. When the first yarn is an absorbent and quick-drying yarn, the moisture absorption and quick-drying performance of the first loop A is enhanced, which is beneficial for perspiration wicking; when the first yarn is a water-repellent yarn, the waterproof performance of the first loop A is enhanced; when the first yarn is a high-strength yarn, the strength and durability of the first loop A are improved; when the first yarn is a PU-coated yarn, after high-temperature setting, the PU on the surface of the first yarn melts, which makes the structure of the area where the first loop A is located more stable, and gives the area where the first loop A is located a stronger integrated support effect.

[0068] During weaving, a four-way loop system is used as one cycle, namely, the first loop L1, the second loop L2, the third loop L3 and the fourth loop L4 constitute one cycle; among them, no yarn is fed into the fourth loop.

[0069] In the first line L1, the intermediate yarn is knitted alternately on the cylinder and needle plate in a loop manner to form the intermediate layer.

[0070] In the second path L2, the yarn is knitted on the needle cylinder in a full-stitch manner to form the surface layer 1. Preferably, in the second path, the following action is also performed: when knitting the second loop strip B, the second yarn is knitted on the needle cylinder in a full-stitch manner to form the second loop strip B. It should be noted that the second yarn can also be knitted using skipped stitches, turning stitches, or tucking stitches.

[0071] In the third path L3, the base yarn forms the bottom layer 3 on the needle plate by skipping needles. The position where the base yarn performs the skipping needle action is defined as the empty needle position. When knitting the first loop strip A, the first yarn is first knitted in a loop on the needle plate and then moved to the needle cylinder to knit in a loop and gathers at the empty needle position to form a transition loop. Alternatively, the first yarn is knitted in a loop on the needle cylinder and gathers at the empty needle position to form a transition loop. After forming a transition loop, the first yarn moves to the needle cylinder to continue knitting.

[0072] In the fourth path (L4), the transition coil unwinding action is performed; one or at least two consecutive transition coils unwind to form the first coil. It should be noted that the unwinding action specifically refers to performing the unwinding action on the transition coil formed in the previous cycle, while the transition coil formed in the current cycle does not unwind in the current cycle. In other words, the transition coil formed in the current cycle only unwinds in the next cycle of the fourth path (L4). In the first cycle, since there is no previous cycle, there is naturally no transition coil formed in the previous cycle; only the unwinding action is performed, but there is no object to unwind. Similarly, if no transition coil was formed in the previous cycle, only the unwinding action is performed, but there is no object to unwind. Furthermore, in the fourth path, at least two unwinding actions are performed for each empty needle position. In this embodiment, two unwinding actions are performed for each empty needle position. By setting two unwinding actions, the success rate of unwinding can be improved, which helps to avoid unsuccessful unwinding.

[0073] After multiple consecutive cycles, multiple first coils are formed to form the first coil bar A.

[0074] Figure 3 At position C, both the top layer 1 and the bottom layer 3 are woven simultaneously.

[0075] It should be noted that the reason why one or at least two consecutive transition coils can form the first coil after unwinding is that when the transition coil is unwinding, it will be pulled onto the surface layer 1 after the subsequent knitting process because it is no longer constrained by the knitting needle.

[0076] Furthermore, in the fourth path L4, two to six transition coils are continuously decoupled to form the first coil.

[0077] Furthermore, the above-mentioned manufacturing method also includes post-processing the greige fabric to obtain jacquard fabric with gradually changing loop width or thickness; the post-processing includes dry heat setting or calendering of the greige fabric. It should be noted that dry heat setting and calendering are both conventional processing techniques. Specifically, a setting machine can be used to set or calender the greige fabric at a temperature of 160-180℃.

[0078] Using the above manufacturing method, during the weaving process, the loop length of the first loop can be effectively increased by the loop gathering and unwinding action, thereby ensuring that the interior of the first loop strip A of the jacquard fabric can form a breathable gap.
