Description

Technical Field

[0001] The invention relates to the technical field of footwear manufacturing, and in particular to a regional transparent knitted shoe upper. Background Art

[0002] In the current field of knitted upper manufacturing, there are many technical solutions to achieve the transparent effect of the upper area. Some knitted uppers are mixed with yarns with a certain degree of transparency during the knitting process, and conventional knitting structures are used to create a semi-transparent or partially slightly transparent upper effect as a whole. However, this method is difficult to achieve precise regional transparency control. The shape and position of the transparent area are relatively fixed, and the transparent effect cannot be flexibly customized in any area according to personalized needs. Some uppers are treated chemically after knitting, such as using special solvents to treat specific areas of the upper, so that the fiber structure of this part changes and becomes transparent. However, this chemical treatment method is often difficult to control accurately, and it is easy to have adverse effects on other parts of the upper, and the chemical residues may affect the wearing experience and the environmental protection of the upper. In addition, there is also a way to create a transparent effect by laminating a transparent film in the corresponding area of ​​the upper. This requires an additional laminating process. First, the cut transparent film is pasted on the predetermined position of the upper, and the adhesion strength must be ensured. In the subsequent wearing process, the film is prone to warping and falling off due to friction, bending, etc., which affects the overall appearance and use effect of the upper. Summary of the invention

[0003] The purpose of the present invention is to solve the problems of existing transparent knitted shoe uppers, such as lack of flexibility and customization of transparent areas, limited ventilation function, high production costs and insufficient comfort.

[0004] To achieve the above object, the present invention adopts the following technical solutions:

[0005] A regional transparent knitted upper, characterized in that it includes an upper base layer and an upper layer arranged on the upper base layer, the upper base layer is formed by a chain of transparent monofilament yarns, the upper layer includes a transparent portion and a plurality of effect portions, the boundary of the transparent portion is formed by densely knitting with auxiliary yarns, and the effect portion is knitted with yarns.

[0006] A further improvement is that the effect portion is located at the edge of the upper and is woven with wear-resistant yarn.

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

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

[0009] A further improvement is that the soft yarn is one of cotton yarn and polyester fiber yarn.

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

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

[0012] A further improvement is that the transparent monofilament yarn is one of 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 arranged between the bottom layer of the upper and the effect part of the upper layer of the upper, and the inner layer of the upper is one of a cotton layer and a mesh polyester fiber layer.

[0015] A method for preparing a regional transparent knitted shoe upper, characterized in that it comprises the following steps:

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

[0017] Step 2: Weaving the bottom layer of the upper, selecting a chain weave as the weaving method, stringing the transparent monofilament yarns in sequence to form longitudinal rows, maintaining a certain spacing distance between adjacent longitudinal rows, so that regular and appropriate gaps are formed between the yarns;

[0018] Step 3: De-lamination weaving of the upper layer of the upper. When weaving the upper layer of the upper, according to the preset transparent part area of ​​the upper, the transparent part is woven with separable auxiliary yarns; the boundary of the transparent part is woven with dense weave to more closely interweave the auxiliary yarns with the surrounding conventional yarns; the effect part is woven normally with plain weave or rib weave;

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

[0020] Step 5: Optimize the overall structure. Add an inner layer between the bottom layer and the upper layer of the upper according to the preset. Use cotton or mesh polyester fiber as the inner layer. The inner layer of the upper at the transparent part is laser punched and microporous woven.

[0027] See also Figure 1-Figure 2 As shown, the technical solution adopted in this specific embodiment is: a regional transparent knitted upper, including an upper bottom layer 1 and an upper layer 2 arranged on the upper bottom layer 1, the upper bottom layer 1 is formed by a transparent monofilament yarn chain, the upper layer 2 includes a transparent part 6 and a plurality of effect parts, the boundary of the transparent part 6 is woven with auxiliary yarn, and the effect part is woven by yarn.

[0028] Wherein, the effect part is located at the edge of the upper and is woven with wear-resistant yarn.

[0029] Wherein, the wear-resistant yarn is a yarn blended from polyester fiber yarn and spandex.

[0030] The effect part is located on the front of the upper and is woven with soft yarn.

[0031] Wherein, the soft yarn is one of cotton yarn or polyester fiber yarn.

[0032] Wherein, 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, some of the effect parts have three colors, and the colors of the first effect part 3, the fourth effect part 7 and the fifth effect part 8 are the same.

[0035] Wherein, the transparent monofilament yarn is one of polyester transparent monofilament yarn or nylon transparent monofilament yarn.

[0036] Wherein, the separable yarn is a soluble yarn or a breakable yarn.

[0037] Wherein, an upper inner layer is arranged between the upper bottom layer 1 and the upper upper layer 2, and the upper inner layer is a cotton layer or a mesh polyester fiber layer.

[0038] A method for preparing a regional transparent knitted shoe upper, characterized in that it comprises the following steps:

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

[0040] Step 2: Weaving the bottom layer of the upper, select the chain weave as the weaving method, string the transparent monofilament yarns in sequence to form longitudinal rows, and keep a certain spacing distance between adjacent longitudinal rows (the spacing distance is set according to the thickness of the yarn and the desired transparency and air permeability), so that regular and appropriate gaps are formed between the yarns, and light can pass through more smoothly, thereby creating a transparent effect. At the same time, these gaps also provide channels for air circulation, which helps to improve the air permeability function; during the weaving process, strictly control the weaving density of each row of yarn to ensure the flatness and uniformity of the entire bottom structure, laying the foundation for the subsequent weaving of the upper layer and the overall upper quality;

[0041] Step 3, de-layer weaving in the upper area of ​​the upper. When weaving the upper area of ​​the upper, according to the preset transparent area of ​​the upper, use separable auxiliary yarn to weave the transparent part (soluble yarn, such as special chemical fiber yarn that can be quickly dissolved in a solution of specific temperature and pH) (or yarn that can be easily broken after special treatment, such as yarn that can be broken by applying a certain external force by setting weak points at specific positions of the yarn); the boundary of the transparent part is woven densely to interweave the auxiliary yarn with the surrounding conventional yarn more closely; the effect part is woven normally with 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 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 upper. After the delamination is completed, along the edge of the transparent part, use a sharp and appropriate cutting tool (such as professional cutting scissors) to finely cut the upper transparent part of the upper, cut off the excess upper fabric of the transparent part, and expose the bottom transparent monofilament yarn layer completely, and finally accurately achieve a transparent effect in the desired area of ​​the upper. During the cutting process, attention should be paid to keeping the edges neat and smooth to avoid unnecessary damage to the bottom transparent fiber layer, and ensure that the boundaries of the transparent area are clear and beautiful, and there will be no burrs, unevenness, and other situations that affect the appearance and quality.

[0043] Step 5: Optimize the overall structure. Add an inner layer between the bottom layer and the upper layer of the upper according to the preset. Use cotton or mesh polyester fiber as the inner layer. The inner layer of the upper at the transparent part is laser punched and microporous woven.

[0044] Working principle of the present invention:

[0045] 1. High degree of customization of transparent areas

[0046] Through the bottom transparent fiber weaving and the upper area delamination process, the transparent effect can be accurately achieved in any desired area of ​​the upper (whether it is a specific pattern shape, a functional area or a part with personalized aesthetic requirements) according to the specific design intention; the transparent area of ​​the upper is no longer limited to the inherent pattern of the traditional weaving method, which greatly improves the degree of personalized customization of the upper, meets the needs of consumers for footwear products to show unique personality and aesthetic pursuit, and brings higher flexibility and creativity to the design of footwear uppers;

[0047] 2. Excellent synergy between breathability and transparency

[0048] Starting from the weaving process itself, on the basis of selecting transparent fiber yarns with good air permeability, the bottom transparent structure is constructed by using a weaving method that is conducive to air permeability, such as a chain weave. At the same time, the upper delamination process and subsequent operations do not hinder the air permeability channel. While the upper presents an ideal regional transparency effect, it ensures that the air can flow smoothly. The air permeability and comfort of the foot are significantly improved when worn, achieving mutual promotion and coordinated optimization of the air permeability function and the transparency effect, so that users can enjoy a wearing experience that is both beautiful and comfortable at the same time.

[0049] 3. Excellent overall quality and durability of the upper

[0050] The transparent effect is achieved by relying on a stable woven structure, and there is no risk of sticking. During long-term wear, the various parts of the upper can work stably together to maintain good integrity and structural strength, effectively resisting wear and tear caused by daily activities and external environmental factors, greatly extending the durability of the upper, ensuring the overall quality of the upper, reducing the occurrence of premature replacement of the upper due to quality problems, and improving the cost-effectiveness of footwear products;

[0051] 4. Simplified production process and cost advantages

[0052] Based on the innovative weaving process, there is no need for complicated chemical treatment processes or additional pasting processes. The customized area transparency effect can be achieved only through reasonable yarn selection, weaving organization design, and orderly weaving, delamination, cutting and other operations. This not only simplifies the production process, reduces the dependence on a variety of special materials and complex process links, and facilitates the control and operation of the production process, but also reduces production costs, improves production efficiency, and reduces production costs;

[0053] 5. Good wearing comfort

[0054] By rationally selecting soft and comfortable yarn materials for the non-transparent areas of the upper, and adding a lining structure with good breathability and touch as needed (while ensuring that the lining does not affect the breathability and visual effect of the transparent area), the contact feeling between the foot and the upper when worn is further optimized. The entire upper structure can naturally adapt to the movement of the foot during wear, and will not cause discomfort to the wearer due to local hardness, airtightness, etc., thereby improving the wearing comfort of footwear products in all aspects, meeting the comprehensive needs of modern consumers for high-quality footwear.
