Abstract
Description
Technical Field
[0001] This utility model relates to the textile field, and more specifically, to an irregularly perforated woven shoe upper. Background Technology
[0002] Traditional two-way woven fabrics are made by interlacing warp and weft yarns on a loom. The longitudinal yarns parallel to the selvage are called warp yarns, and the transverse yarns perpendicular to the selvage are called weft yarns. The intersection of warp and weft yarns is called the weft point. After decades of development in the textile industry, woven fabrics have become the main material for shoe uppers. However, since the warp and weft yarns of woven fabrics are interlaced, the gaps between the yarns are smaller, so woven fabrics have poorer breathability than knitted fabrics.
[0003] Existing woven fabrics have already encountered the problem of using heddle structures to weave leno weaves to improve the breathability of woven fabrics. The main principle of leno weave is to twist the warp yarns left and right to make the warp yarns occupy more space in the heddle group, while separating adjacent heddle groups. Twisting also separates adjacent weft yarns, preventing them from sticking together, thus forming yarn holes and improving the fabric's breathability. However, leno weave requires the installation of multiple heddle structures on the loom to achieve, making the weaving process relatively cumbersome. At the same time, because the yarn twisting creates uneven points at the weave points, it affects wearing comfort. Therefore, the applicant proposes a perforated woven shoe upper fabric that does not require warp yarn twisting but can increase the porosity of the weave points. Utility Model Content
[0004] This invention provides an irregularly perforated woven shoe upper, aiming to improve the technical problems of the cumbersome weaving and poor wearing comfort of existing woven fabrics with leno weave.
[0005] An irregular perforated woven shoe upper includes a perforated structure and a regular textured structure. The number of warp yarns at the perforated structure point is two or more, the number of weft yarns at the perforated structure point is two or more, all warp and weft yarns at the same perforated structure point are bundled together, all weft yarns at the same perforated structure point are bundled together, and the perforated structure and the regular textured structure are woven together continuously.
[0006] This utility model provides a loom for weaving the above-mentioned irregular perforated woven shoe upper. The loom structure includes: a warp feeding mechanism, a shedding mechanism, a weft insertion mechanism, a beat-up mechanism, and a crimping mechanism. The shedding mechanism includes:
[0007] The first heddle group consists of a column of at least two metal heddles.
[0008] The second heddle group consists of a column of at least two metal heddles.
[0009] The first and second heald sets are arranged sequentially along the direction of the weft yarn;
[0010] The loom also includes a jacquard mechanism, which independently controls the metal heddles to move up and down alternately according to the design.
[0011] Furthermore, the metal heddles of the first heddle group include a first metal heddle and a second metal heddle. The first metal heddle is raised and the second metal heddle is lowered to form a shed. Two or more weft yarns are introduced into the shed, and the warp and weft yarns are beaten to form a perforated structure.
[0012] Furthermore, the width of the loom determines the number of rows of heddle frames. A rapier loom typically has 25 to 30 rows of heddle frames.
[0013] Furthermore, the upper end of the metal heald is connected to the jacquard mechanism, and the lower end of the metal heald is connected to the loom body through a spring. The metal heald has a grommets in the middle for the warp yarns to pass through. The metal heald moves up and down alternately to lift some of the warp yarns and sink others to form a shed. The first heald group includes at least two metal heals, and the second heald group includes at least two metal heals.
[0014] Furthermore, the metal heddles of the second heddle group include a third metal heddle and a fourth metal heddle. The third metal heddle is controlled to rise and the fourth metal heddle is controlled to sink to form a shed and introduce a weft yarn. The warp and weft yarns are beaten to form a normal texture structure.
[0015] Furthermore, the warp feeding mechanism includes an upper warp beam and a lower warp beam, both of which are wound with warp yarns.
[0016] Furthermore, the weft insertion mechanism includes a rapier arrow, through which the weft yarn is introduced into the shed.
[0017] Furthermore, the beat-up mechanism includes a reed, which pushes the weft yarn toward the weft end to complete the warp and weft yarn interlacing.
[0018] This utility model also provides a method for weaving irregular perforated woven shoe uppers, using the above-mentioned loom for weaving irregular perforated woven shoe uppers, and the weaving steps are as follows:
[0019] S1. Pass the warp yarns of the upper and lower warp beams through the eyelets of the metal heddles according to the pre-design requirements. Each warp yarn is controlled by a corresponding metal heddle. After the warp yarn passes through the eyelet, insert two or more warp yarns to be bundled into the same tooth of the reed. Therefore, when a bundle of warp yarns is inserted into a tooth of the reed, the adjacent teeth will not insert warp yarns and will form an empty reed.
[0020] S2. When weaving a perforated structure, the first metal helium of the first helium group is raised and the second metal helium is lowered to form a shed. Two or more weft yarns are introduced into the shed. The bundled warp yarns on the same reed tooth and the multiple weft yarns on the same shed are gathered together to form a perforated structure with holes between the weaving points.
[0021] S3. When weaving a normal weave, the third metal helium of the adjacent second helium group is raised and the fourth metal helium is lowered to form a shed and introduce a weft yarn. At this time, the warp and weft yarns do not gather into a bundle, forming a normal weave.
[0022] S4. Repeat steps two and three above to weave the predetermined perforated structure and ordinary texture in the predetermined design area to obtain a woven shoe upper fabric with the perforated structure and ordinary texture woven together. According to the pre-design, the woven shoe upper fabric can be woven together to form more than three shoe uppers along the weft direction. The woven shoe upper fabric can be cut into pieces along the shape of the shoe upper using a laser cutting machine. The pieces of woven shoe upper can then be used for the next process of shoe production.
[0023] Preferably, in step S3, the common texture is one or more of the following: plain weave, twill weave, satin weave, plain weave variation, twill weave variation, and satin weave variation.
[0024] Preferably, the number of weft yarns introduced into the shed of the first heddle group and the second heddle group is variable. When one weft yarn is introduced into the shed of the first heddle group, a normal texture structure is formed. When two or more weft yarns are introduced into the shed of the second heddle group, a perforated structure is formed.
[0025] Preferably, the metal heldons of the first heldon group and the metal heldons of the second heldon group are arranged closely in sequence along the direction of the weft yarn, so the openwork structure and the ordinary texture structure are woven continuously in one go, and the dividing line between the openwork structure and the ordinary texture structure can form an irregular curve.
[0026] Beneficial effects:
[0027] This invention utilizes a specific loom and weaving method to create an irregularly perforated woven shoe upper. The perforated structure and the ordinary texture structure are woven continuously in one pass, and all warp and weft yarns at the same weave point in the perforated structure are bundled together to form ventilation holes between the weave points. This achieves the goal of increasing the porosity of the weave points without warp yarn twisting. At the same time, the boundary line between the perforated structure and the ordinary texture structure can form an irregular curve, which not only adds a pattern to the fabric but also improves its breathability, solving the problem of poor breathability of woven fabrics.

Detailed Implementation
[0040] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model. Therefore, the following detailed description of the embodiments of this utility model provided in the accompanying drawings is not intended to limit the scope of the claimed utility model, but merely represents selected embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.
[0041] Example 1, please refer to Figures 1 to 3 The first embodiment of this utility model provides a loom for weaving irregular perforated woven shoe uppers, including: a warp feeding mechanism 1, an shedding mechanism 2, a weft insertion mechanism 3, a beat-up mechanism 4, a crimping mechanism 5, and a jacquard mechanism 6; the shedding mechanism 2 includes 30 rows of heddle groups, each row of heddle groups is composed of two metal heddles 21, and the heddle groups are arranged sequentially along the travel direction of the weft yarn 8; the jacquard mechanism 6 independently controls the metal heddles 21 to move up and down alternately according to the set design.
[0042] Specifically, the upper end of the metal heddle 21 is connected to the jacquard mechanism 6, and the lower end of the metal heddle 21 is connected to the loom body through a spring. The metal heddle 21 has a grommets 213 in the middle through which the warp yarns 7 can pass. The metal heddle 21 moves up and down alternately independently, causing some of the warp yarns 7 to rise and others to sink to form a shed.
[0043] In addition, the warp feeding mechanism 1 includes an upper warp beam 101 and a lower warp beam 102, both of which are wound with warp yarns 7.
[0044] Meanwhile, the weft insertion mechanism 3 includes a rapier arrow, through which the weft yarn 8 is introduced into the shed. The beat-up mechanism 4 includes a reed 401, which pushes the weft yarn 8 toward the weft end to complete the warp and weft yarn interlacing.
[0045] Specifically, please refer to Figures 4 to 6 Using the aforementioned loom, the weaving steps for weaving an irregularly perforated woven shoe upper in this embodiment are as follows:
[0046] S1. The warp yarns 7 of the upper warp beam 101 and the lower warp beam 102 are passed through the eyelets 213 of the metal heald 21 according to the pre-design requirements. Each warp yarn 7 is controlled by a corresponding metal heald 21. After the warp yarn 7 passes through the eyelet 213, two or more warp yarns 7 to be bundled are passed into the same tooth of the reed 401. Therefore, when a bundle of warp yarns is passed into a tooth, the adjacent teeth will not pass into warp yarns and will form an empty reed.
[0047] S2. When weaving the perforated structure 901, the first metal helium 211 of the first helium group is raised and the second metal helium 212 is lowered to form a shed. Three weft yarns 8 are introduced into the shed. The bundled warp yarns 7 on the same reed tooth and the multiple weft yarns 8 on the same shed are gathered into a bundle to form a perforated structure 901 with holes between the weaving points.
[0048] S3. When weaving the ordinary texture 902, the third metal helium 221 of the adjacent second helium group is raised and the fourth metal helium 222 is lowered to form a shed and introduce a weft yarn 8. At this time, the warp and weft yarns are not bundled together, forming the ordinary texture 902. The 30 helium groups on the loom weave the perforated texture 901 and the ordinary texture 902 in the area according to the predetermined design. At the same time, the number of weft yarns 8 introduced into the shed of the helium group is variable. When the shed of the first helium group introduces one weft yarn 8, the ordinary texture 902 is formed. When the shed of the second helium group introduces three weft yarns 8, the perforated texture 901 is formed.
[0049] S4. Repeat steps two and three above to weave the predetermined perforated structure 901 and ordinary texture structure 902 in the predetermined design area to obtain a woven shoe upper fabric 9 woven with the perforated structure 901 and ordinary texture structure 902. According to the pre-design, in this embodiment, the woven shoe upper fabric 9 can be woven into 3 shoe uppers in one go along the weft direction. The woven shoe upper fabric 9 is then cut into pieces along the shape of the shoe upper by a laser cutting machine. The pieces of woven shoe upper can then be used for the next process of shoe production.
[0050] In step S3 of this embodiment, the ordinary texture 902 is a plain texture area.
[0051] Please see Figures 7 to 9 In this embodiment, the perforated structure 901 and the ordinary texture structure 902 of the woven shoe upper are woven together continuously.
[0052] Specifically, such as Figure 8As shown, the first warp 701, third warp 703, fourth warp 704, sixth warp 706, and weft 8 have more interlacing points, while the second warp 702, fifth warp 705, and weft 8 sandwiched in the middle have fewer interlacing points and longer floats. This configuration separates the third warp 703 and fourth warp 704 from each other, and also separates the third weft 803 and fourth weft 804 from each other, thus bringing the first warp 701, second warp 702, and third warp 703 together. The fourth warp yarn 704, the fifth warp yarn 705, and the sixth warp yarn 706 are bundled together, the first weft yarn 801, the second weft yarn 802, and the third weft yarn 803 are bundled together, and the fourth weft yarn 804, the fifth weft yarn 805, and the sixth weft yarn 806 are bundled together. Therefore, holes are formed between the third warp yarn 703 and the fourth warp yarn 704, and holes are formed between the third weft yarn 803 and the fourth weft yarn 804. This allows holes to be formed between the yarn weaving points without twisting the warp yarns, thus improving the permeability of the fabric.
[0053] Example 2, refer to Figure 10 This is a structural schematic diagram provided by the second embodiment of the present invention. The structure of the second embodiment is largely the same as that of the first embodiment. The difference is that when weaving the perforated structure 901, the number of weft yarns 8 introduced into the shed is five. In this embodiment, because the number of weft yarns 8 introduced into the shed is five, the bundled warp yarns 7 on the same reed tooth and the five weft yarns 8 on the same shed are more clustered together. Therefore, the holes between the weaving points are larger than the holes in the first embodiment with three weft yarns introduced, and the permeability is better.
[0054] The second embodiment of this utility model has the same implementation principle and technical effects as the first embodiment. For the sake of brevity, any parts not mentioned in this embodiment can be referred to the corresponding content in the first embodiment.
[0055] The above are merely preferred embodiments of this utility model and are not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
