Description

Technical Field

[0001] This utility model relates to the field of footwear manufacturing technology, specifically to a regionally transparent knitted shoe upper. Background Technology

[0002] In the current field of knitted shoe upper manufacturing, various technical solutions exist to achieve a transparent effect in specific areas of the upper. Some knitted uppers incorporate yarns with a certain degree of transparency during the weaving process, using conventional weaving structures to create a uniformly semi-transparent or partially transparent upper effect. However, this method struggles to achieve precise control over the transparency of specific areas; the shape and position of the transparent areas are relatively fixed, preventing flexible customization of transparency in any area to meet individual needs. Other uppers undergo chemical treatment after weaving, such as using special solvents to treat specific areas of the upper, altering the fiber structure and making them transparent. However, this chemical treatment method is often difficult to control precisely, potentially causing adverse effects on other parts of the upper, and chemical residues may affect the wearing experience and the environmental friendliness of the upper. Additionally, some methods create a transparent effect by laminating a transparent film to specific areas of the upper. This requires an additional lamination process, where the cut transparent film is first pasted onto the predetermined position on the upper, ensuring a secure bond. During subsequent wear, the film is prone to curling or detachment due to friction and bending, affecting the overall aesthetics and usability of the upper. Utility Model Content

[0003] The purpose of this invention is to solve the problems of existing transparent knitted shoe uppers, such as lack of flexibility and customization in the transparent area, limited breathability, high production cost, and insufficient comfort.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A regionally transparent knitted shoe upper, characterized in that: it includes a bottom layer of shoe upper and an upper layer of shoe upper disposed on the bottom layer of shoe upper, the bottom layer of shoe upper is made of transparent monofilament yarn braided together, the upper layer of shoe upper includes a transparent part and a plurality of effect parts, the boundary of the transparent part is densely woven with auxiliary yarn, and the effect parts are woven with yarn.

[0006] A further improvement is that the effect section located at the edge of the shoe upper is woven with abrasion-resistant yarn.

[0007] A further improvement is that the wear-resistant yarn is a blend of polyester fiber yarn and spandex.

[0008] A further improvement is that the effect section located on the front of the shoe upper is woven with soft yarn.

[0009] A further improvement is that the soft yarn is either cotton yarn or polyester fiber yarn.

[0010] A further improvement is that the effect section is made of plain weave or rib weave.

[0011] A further improvement is that the plurality of effect sections include a first effect section, a second effect section, a third effect section, a fourth effect section, and a fifth effect section.

[0012] A further improvement is that the transparent monofilament yarn is either polyester transparent monofilament yarn or nylon transparent monofilament yarn.

[0013] A further improvement is that the separable yarn is a soluble yarn or a breakable yarn.

[0014] A further improvement is that an inner layer of the upper is provided between the bottom layer of the upper and the upper layer of the upper, and the inner layer of the upper is either a cotton layer or a mesh polyester fiber layer.

[0015] A method for preparing a regionally transparent knitted shoe upper, characterized by comprising the following steps:

[0016] Step 1: Selection of yarn materials. Transparent monofilament yarn is selected as the weaving material for the bottom layer of the shoe upper, abrasion-resistant yarn is selected as the weaving material for the edge of the upper effect part, soft yarn is selected as the weaving material for the main part of the upper effect part, and separable auxiliary yarn is selected as the weaving material for the upper transparent part.

[0017] Step 2: Weaving the bottom layer of the shoe upper. A chain weave is selected as the weaving method. Transparent monofilament yarns are interlaced to form longitudinal rows, with a certain interval between adjacent longitudinal rows, so that the yarns form regular and appropriate gaps.

[0018] Step 3: Delamination weaving of the upper layer of the shoe upper. When weaving the upper layer of the shoe upper, according to the pre-set transparent area of ​​the shoe upper, separable auxiliary yarns are used to weave the transparent area; the boundary of the transparent area is densely woven to interweave the auxiliary yarns more tightly with the surrounding regular yarns; the effect area is woven normally using plain weave or rib weave.

[0019] Step 4: Delamination and Cutting. After weaving the upper layer of the shoe upper, delamination is performed according to the type of separable yarn selected, so that the yarn in the transparent area is delaminated and separated from the other parts of the shoe upper. After delamination is completed, fine cutting is performed along the edge of the transparent area to cut off the excess upper fabric of the transparent area, so that the bottom transparent monofilament yarn layer is completely exposed.

[0020] Step 5: Overall structural optimization. According to the preset, add an inner layer of the shoe upper between the bottom layer and the top layer of the shoe upper. Cotton or mesh polyester fiber is used as the inner layer. The inner layer of the shoe upper in the transparent part is treated with laser perforation and micro-perforation weaving.

[0021] Compared with existing technologies, the above technical solution has the following advantages:

[0022] It has enabled the manufacturing of custom-designed transparent knitted uppers, ensuring upper quality, breathability, and transparency in synergy while allowing for customization of transparent areas. This simplifies the production process, saves costs, and provides excellent comfort. Attached Figure Description

[0027] See Figures 1-2 As shown, the technical solution adopted in this specific embodiment is: a regional transparent knitted shoe upper, including a bottom shoe upper 1 and an upper shoe upper 2 disposed on the bottom shoe upper 1. The bottom shoe upper 1 is made of transparent monofilament yarn braided and woven. The upper shoe upper 2 includes a transparent part 6 and several effect parts. The boundary of the transparent part 6 is made of auxiliary yarn densely woven. The effect parts are woven with yarn.

[0028] The effect section, located at the edge of the shoe upper, is woven from wear-resistant yarn.

[0029] The wear-resistant yarn is a blend of polyester fiber yarn and spandex.

[0030] The effect section, located on the front of the shoe upper, is woven from soft yarn.

[0031] The soft yarn is either cotton yarn or polyester fiber yarn.

[0032] The effect part is made of plain weave or rib weave.

[0033] Among them, the plurality of effect parts include a first effect part 3, a second effect part 4, a third effect part 5, a fourth effect part 7, and a fifth effect part 8.

[0034] Among them, several of the effect parts are three colors, and the first effect part 3, the fourth effect part 7 and the fifth effect part 8 are the same color.

[0035] The transparent monofilament yarn is either polyester transparent monofilament yarn or nylon transparent monofilament yarn.

[0036] The separable yarn is either a soluble yarn or a breakable yarn.

[0037] An inner layer of the shoe upper is provided between the bottom layer 1 and the upper layer 2 of the shoe upper, and the inner layer of the shoe upper is either a cotton layer or a mesh polyester fiber layer.

[0038] A method for preparing a regionally transparent knitted shoe upper, characterized by comprising the following steps:

[0039] Step 1: Selection of yarn materials. Transparent monofilament yarn is selected as the weaving material for the bottom layer of the shoe upper, abrasion-resistant yarn is selected as the weaving material for the edge of the upper effect part, soft yarn is selected as the weaving material for the main part of the upper effect part, and separable auxiliary yarn is selected as the weaving material for the upper transparent part.

[0040] Step Two: Weaving the Underbody of the Upper. A chain weave is chosen as the weaving method, where transparent monofilament yarns are interlaced to form longitudinal rows, maintaining a certain spacing between adjacent rows (the spacing is set according to the yarn thickness and the desired transparency and breathability). This creates regular and appropriate gaps between the yarns, allowing light to pass through more smoothly, thus creating a transparent effect. These gaps also provide channels for air circulation, contributing to improved breathability. During the weaving process, the weaving density of each row of yarn is strictly controlled to ensure the flatness and uniformity of the entire underbody structure, laying the foundation for the subsequent upper weaving and the overall quality of the upper.

[0041] Step 3: Delamination weaving of the upper layer. When weaving the upper layer, according to the pre-designed transparent area of ​​the upper, separable auxiliary yarns are used to weave the transparent area (soluble yarns, such as special chemical fiber yarns that can be quickly dissolved in solutions with specific temperatures and pH levels) (or yarns that can be easily broken after special treatment, such as yarns that can be broken by setting weak points at specific locations and applying a certain external force); the boundary of the transparent area is densely woven to interweave the auxiliary yarns more tightly with the surrounding regular yarns; the effect area is woven normally using plain weave or rib weave to ensure the overall structural integrity and strength of the upper.

[0042] Step 4: Delamination and Cutting. After weaving the upper layer of the shoe upper, delamination is performed according to the type of separable yarn selected, so that the yarn in the transparent area is delaminated and separated from the rest of the shoe upper. After delamination, use a sharp and appropriate cutting tool (such as professional cutting scissors) to carefully cut the upper transparent part of the shoe upper along the edge of the transparent part, cutting off the excess upper fabric of the transparent part, so that the bottom transparent monofilament yarn layer is completely exposed, and finally achieving a precise transparent effect in the desired area of ​​the shoe upper. During the cutting process, pay attention to keeping the edges neat and smooth, avoiding unnecessary damage to the bottom transparent fiber layer, ensuring that the boundary of the transparent area is clear and beautiful, and that there are no rough edges, unevenness, or other issues that affect the appearance and quality.

[0043] Step 5: Overall structural optimization. According to the preset, add an inner layer of the shoe upper between the bottom layer and the top layer of the shoe upper. Cotton or mesh polyester fiber is used as the inner layer. The inner layer of the shoe upper in the transparent part is treated with laser perforation and micro-perforation weaving.

[0044] The working principle of this utility model:

[0045] I. High degree of customizability of transparent areas

[0046] By using a bottom layer of transparent fiber weaving and a top layer delamination process, a transparent effect can be precisely achieved in any desired area of ​​the shoe upper (whether it is a specific pattern shape, functional area, or part of a personalized aesthetic requirement) according to specific design intentions. This makes the transparent area of ​​the shoe upper no longer limited by the inherent pattern of traditional weaving methods, greatly improving the degree of personalization of the shoe upper, meeting consumers' needs for footwear products to show unique personality and aesthetic pursuit, and bringing greater flexibility and creativity to footwear upper design.

[0047] II. Excellent synergy between breathability and transparency

[0048] Starting from the weaving process itself, based on the selection of transparent fiber yarns with good breathability, the bottom transparent structure is constructed by using weaving methods such as chain braiding to facilitate breathability. At the same time, the upper delamination process and subsequent operations do not obstruct the breathability channels. While presenting an ideal regional transparency effect, the upper ensures that air can circulate smoothly, and the breathability and comfort of the feet are significantly improved when wearing. This achieves mutual promotion and synergistic optimization of breathability and transparency, allowing users to enjoy a wearing experience that combines aesthetics and comfort.

[0049] III. Excellent overall quality and durability of the shoe upper

[0050] The transparent effect is achieved through a stable weaving structure, eliminating the risk of adhesive issues. During long-term wear, the various parts of the upper can work stably and collaboratively to maintain good integrity and structural strength, effectively resisting wear and tear caused by daily activities and external environmental factors. This greatly extends the durability of the upper, ensures the overall quality of the upper, reduces the occurrence of premature replacement of the upper due to quality problems, and improves the cost-effectiveness of footwear products.

[0051] IV. Simplified Production Process and Cost Advantages

[0052] Based on innovative weaving technology, no complex chemical treatment process or additional bonding process is required. Custom transparent areas can be achieved simply by selecting appropriate yarns, designing the weaving structure, and carrying out orderly weaving, delamination, and cutting operations. This not only simplifies the production process and reduces the reliance on various special materials and complex processes, making it easier to control and operate the production process, but also reduces production costs, improves production efficiency, and reduces production costs.

[0053] V. Excellent wearing comfort

[0054] By selecting soft and comfortable yarn materials for the non-transparent areas of the shoe upper and adding breathable and comfortable linings as needed (while ensuring that the lining does not affect the breathability and visual effect of the transparent areas), the contact feeling between the foot and the shoe upper is further optimized. The entire upper structure can naturally conform to the foot's movements during wear, and will not cause discomfort to the wearer due to problems such as excessive stiffness or lack of breathability in certain areas. This comprehensively improves the wearing comfort of footwear products and meets the comprehensive needs of modern consumers for high-quality footwear.
