Description

Technical Field

[0001] This invention relates to a shoe upper, and more specifically, to a shoe upper comprising a three-dimensional pattern. Background Technology

[0002] Typically, a shoe consists of a sole and uppers. The sole is the part that contacts the ground, and the uppers are combined with the sole to wrap around the wearer's foot.

[0003] To improve the ease and efficiency of manufacturing the shoes as described above, the upper can be woven into a one-piece form. However, details regarding uppers woven in this one-piece form are described in detail in Korean Patent No. 10-1437472 (August 28, 2014). Furthermore, details regarding looms for weaving heterogeneous fabrics, uppers woven using such looms, and shoes are described in detail in Korean Patent No. 10-1557130 (September 24, 2015).

[0004] However, inserting logos or other patterns onto the shoe upper requires additional sewing work to attach separately manufactured pattern components to the upper. In particular, inserting three-dimensional patterns into the shoe upper requires a process for creating the three-dimensional pattern and then sewing the pattern onto the upper, which is highly complex and increases manufacturing costs.

[0019] The embodiments of the present invention will now be described in detail with reference to the accompanying drawings.

[0020] In this instruction manual, the fabric is broadly classified into basic structure and twisted structure.

[0021] In this specification, basic weave refers to fabrics made by neatly twisting warp and weft yarns together. Plain weave, twill weave, and satin weave are the three basic weaves that belong to this category.

[0022] In this specification, a twisted structure refers to a fabric in which the weft yarns are arranged side by side, but the warp yarns are spaced apart and interchanged to form a twist. Gauze weave belongs to this category. In the gypze weave, the weft yarn is the center, and two warp yarns form a pair, which cross each other and twist to form an opening. The weft yarn passes through the opening for weaving.

Figure 4 A diagram of the cross-section of A cut at L3-L3'.

[0027] Reference Figures 1 to 4 According to a specific example of an embodiment of the present invention, the upper 100 including a three-dimensional pattern is woven using warp yarns 113 and weft yarns 111, 112. As described in more detail below, the upper 100 according to the present invention is an upper continuously woven from a basic weave fabric and a leno weave fabric.

[0028] In this invention, the weft yarns 111 and 112 are formed by overlapping a first weft yarn 111, which is a high-elastic yarn, and a second weft yarn 112, which is a regular yarn. The high-elastic yarn constituting the first weft yarn 111 can be, for example, polyurethane high-elastic yarn, and the regular yarn constituting the second weft yarn 112 can be, for example, ordinary polyester false twist yarn or recycled polyester yarn, and is not limited thereto.

[0029] In addition, at least one of the warp yarns can be transparent.

[0030] Furthermore, the upper of the shoe of the present invention includes three-dimensional patterned areas 110 and 130a, wherein the three-dimensional patterned areas 110 and 130a are disposed inside by a first weft yarn 111 and a second weft yarn 112 is disposed on the surface, thereby forming a three-dimensional pattern on the surface.

[0031] In this instruction manual, unless otherwise specified, "surface" refers to the side of the upper that is visible on the outside of the shoe, and "inside" refers to the other side of the upper that is inside the shoe and not visible on the outside.

[0032] In the three-dimensional pattern areas 110 and 130a that form a three-dimensional pattern on the surface of the shoe upper, the second weft yarn 112, which is a regular yarn, is arranged so that it protrudes from the surface of the shoe upper, while the first weft yarn 111, which is a high-elastic yarn, is arranged inside. With this configuration, as the first weft yarn 111, which is a high-elastic yarn, arranged inside the shoe upper shrinks, the second weft yarn 112, which is a regular yarn, arranged on the surface of the shoe upper does not shrink but protrudes, thus forming a three-dimensional pattern on the surface of the shoe upper.

[0033] In another specific example according to the invention, the upper of the shoe also includes patternless areas 120 and 130b, which are disposed on the surface by a first weft yarn 111 and disposed inside by a second weft yarn 112, so that no three-dimensional pattern is formed on the surface.

[0034] In the patternless areas 120 and 130b on the surface of the shoe upper where no three-dimensional pattern is formed, the first weft yarn 111, which is a high-elastic yarn, is arranged so that it protrudes from the surface of the shoe upper, while the second weft yarn 112, which is a regular yarn, is arranged inside. With this configuration, as the first weft yarn 111, which is a high-elastic yarn, arranged on the surface of the shoe upper shrinks, no three-dimensional pattern is formed on the surface of the shoe upper. At this time, the second weft yarn 112, which is a regular yarn, can protrude into the inside of the shoe upper without shrinking.

[0035] In another specific example according to the present invention, the three-dimensional patterned area and the unpatterned area of ​​the shoe upper are continuously woven in a seamless manner. For example... Figure 4 As shown, in the area where the three-dimensional patterned area and the unpatterned area meet, the first weft yarn 111 and the second weft yarn 112 are twisted and supplied in a manner that their positions intersect each other. For example, the first weft yarn 111, which was previously disposed on the surface of the shoe upper, is disposed on the inside of the shoe upper, and the second weft yarn 112, which was previously disposed on the inside of the shoe upper, is disposed on the surface of the shoe upper. Although Figure 2 and Figure 3 Not shown in the image, but related to Figure 4 As shown in the diagram, the first weft yarn 111 and the second weft yarn 112 can also be configured to cross each other and be arranged alternately.

[0036] The three-dimensional patterned area and the unpatterned area can be jacquard fabrics woven by a jacquard loom.

[0037] Typically, fabrics are woven in the following way: to allow the warp yarns to pass through, the warp yarns are inserted into the heddle eye located in the center of the heddle and allowed to pass through. Then, the warp yarns rise and fall according to the up-and-down movement of the heddle, creating an opening between adjacent warp yarns. The weft yarn is then inserted into this opening. Depending on the type of opening device, fabrics can be divided into dobby fabrics, which can be woven with simple weaves or small patterns, and jacquard fabrics, which can be woven with large or complex patterns. Jacquard fabrics are fabrics woven using a jacquard loom. The weaving process of a jacquard loom involves adjusting each warp yarn with an independent heddle. The heddle is not fixed to the heddle frame but moves up and down independently. Simultaneously adjusting the heddle movement creates an opening between the warp yarns, and the weft yarn is inserted into this opening to weave the fabric. Jacquard fabrics have the advantage of being able to form diverse and complex patterns.

[0038] Figure 2 The basic weave structure of the three-dimensional patterned area of ​​the upper according to a specific example of the present invention is schematically shown. Figure 3 A diagram illustrating the basic weave structure of the unpatterned area of ​​the upper according to a specific example of the invention.

[0039] Reference Figure 2 and Figure 3 In another specific example of the shoe upper according to the present invention, the three-dimensional patterned area and the unpatterned area respectively include a basic weave three-dimensional patterned area 110 and a basic weave unpatterned area 120 woven with a basic weave.

[0040] Specifically, warp yarns 113 and first weft yarns 111 are configured such that the weave point values ​​of warp yarns 113 and first weft yarns 111 are smaller in the three-dimensional patterned area of ​​the basic structure compared to the patternless area 120 of the basic structure.

[0041] In this invention, the weave point value refers to a numerical value representing the degree to which warp and weft yarns intersect in the fabric structure. It is expressed as follows: when warp and weft yarns intersect in the fabric structure, the numerator is recorded as 1, and the number of warp yarns forming the repeating unit of the structure is recorded as the denominator. For example, in a plain weave, the number of warp yarns forming the repeating unit [1up 1down] is 2. Therefore, the weave point value of a plain weave is 1 / 2, making it the weave with the largest weave point value and the strongest weave. Furthermore, in the case of a 4-end twill weave (3up 1down), the weave point value is 1 / 4, and in the case of an 8-end twill weave (7up 1down), the weave point value is 1 / 8. Therefore, a small weave point value indicates a sparse weave in the fabric.

[0042] Reference Figure 2Looking at the weave point values ​​of warp yarn 113 and the first weft yarn 111 in the direction indicated by arrow a, as a 7up 1down weave, the weave point value is 1 / 8. At this time, the first weft yarn 111, which is a high-elastic yarn, is connected to another down point adjacent to the down point of the warp yarn, and can shrink by a distance represented by D1.

[0043] Additionally, refer to Figure 3 The weft point values ​​of warp yarn 113 and first weft yarn 111, when viewed in the direction indicated by arrow b, are 1 / 4 of the 3up 1down weave. At this time, the first weft yarn 111, which is a high-elastic yarn, is connected to another down point adjacent to the down point of the warp yarn. Therefore, the distance represented by D2 can be contracted.

[0044] Therefore, the distance represented by D1 is larger than the distance represented by D2. Compared to the first weft yarn 111 in the basic weave patternless region 120, the first weft yarn 111 in the basic weave three-dimensional patterned region 110, in which the warp and weft yarns are arranged in a manner that ensures the distance represented by D1, can shrink more, so that the second weft yarn 112 can correspondingly protrude more towards the surface, thereby maximizing the effect of the three-dimensional pattern.

[0045] Therefore, by configuring the warp yarn 113 and the first weft yarn 111, the weave point values ​​of the warp yarn 113 and the first weft yarn 111 are compared to those in the patternless area 120 of the basic weave. Figure 3 In the case of a tissue point value of 1 / 4, in the basic tissue three-dimensional pattern area 110 ( Figure 2 In this case, the organization point value is smaller (1 / 8), so that in the basic three-dimensional pattern area 110, the second weft yarn 112 protrudes further to the surface, which can maximize the effect of the three-dimensional pattern.

[0046] Reference Figure 2 and Figure 3 In the upper of a shoe according to another specific example of the invention, warp yarns 113 and second weft yarns 112 are configured such that the weave point values ​​of warp yarns 113 and second weft yarns 112 are the same in the basic weave three-dimensional patterned area 110 and the basic weave unpatterned area 120.

[0047] That is, the warp yarn 113 and the first weft yarn 111 are configured such that the weft point values ​​of the warp yarn 113 and the first weft yarn 111 are smaller in the basic weave three-dimensional patterned region 110 compared to the basic weave plain region 120. The warp yarn 113 and the second weft yarn 112 are configured such that the weft point values ​​of the warp yarn 113 and the second weft yarn 112 are the same in the basic weave three-dimensional patterned region 110 and in the basic weave plain region 120. Thus, the second weft yarn 112, which is a regular yarn, is connected at the same distance to another lower point adjacent to the lower point of the warp yarn. The effect of the three-dimensional pattern can be maximized by only changing the shrinkage distance of the first weft yarn 111, which is a high-elastic yarn.

[0048] Reference Figure 2 and Figure 3 In a shoe upper according to another specific example of the invention, warp yarns 113 and weft yarns 111, 112 are arranged in the basic weave plain area 120 such that the weave point values ​​of the warp yarns 113 and the first weft yarn 111 are greater than or equal to the weave point values ​​of the warp yarns 113 and the second weft yarn 112. The first weft yarn 111, which is a high-elastic yarn, shrinks (does not protrude), while the second weft yarn 112, which is a regular yarn, protrudes when the first weft yarn 111 shrinks. However, in the basic weave plain area 120, the second weft yarn 112, which is arranged inside the shoe upper, does not need to protrude. Therefore, the first weft yarn 111, which is a high-elastic yarn, is arranged to be more tightly connected than the second weft yarn 112, which is a regular yarn, so that the basic weave plain area 120 can be formed flat.

[0049] Figure 4 The diagram illustrates, in a schematic manner, the weaving structure of the three-dimensional patterned area and the unpatterned area of ​​the gauze fabric in the upper of a shoe according to a specific example of the present invention.

[0050] Reference Figure 4 In another specific example of the shoe upper according to the invention, the warp yarns include a first warp yarn 113a and a second warp yarn 113b, the first warp yarn 113a and the second warp yarn 113b are crossed in opposite directions and twisted to form openings a and b, and the weft yarns pass through the openings to form a leno weave fabric.

[0051] Gauze weave fabric is centered around the weft yarn and consists of two warp yarns that cross each other in opposite directions and are twisted together. Generally speaking, it can be woven with the first warp yarn always passing above the weft yarn and the second warp yarn always passing below the weft yarn.

[0052] The opening includes a first opening a through which the first weft yarn 111 and the second weft yarn 112 pass together, and a second opening b through which only the second weft yarn 112 passes.

[0053] In addition, the three-dimensional patterned area and the unpatterned area respectively include a three-dimensional patterned area 130a of gauze fabric woven with gauze fabric and an unpatterned area 130b of gauze fabric woven with gauze fabric.

[0054] In the three-dimensional patterned area 130a of the leno weave, one or more second openings b are arranged between the first opening a and other adjacent first openings a'. The first weft yarn 111, being a high-elasticity yarn, is connected via other first openings a' adjacent to the first opening a, thus allowing it to be arranged according to... Figure 4 The shrinkage is represented by the distance D4. Therefore, the larger the distance represented by D4, the greater the shrinkage distance of the first weft yarn 111, which is a high-elastic yarn, and thus the more it can shrink. The second weft yarn 112, which is a regular yarn, can be correspondingly more prominent, thereby maximizing the effect of the three-dimensional pattern.

[0055] Reference Figure 4 In the upper of a shoe according to another specific example of the invention, the warp and weft yarns are arranged such that the number of second openings b between the first opening a and the other first openings a' adjacent thereto is greater in the three-dimensional patterned area 130a of the leno weave than in the patternless area 130b of the leno weave.

[0056] like Figure 4 As shown, in the case of the patternless region 130b of the leno weave, the first weft yarn 111 is connected by other first openings a' adjacent to the first opening a, thereby allowing it to be arranged according to the pattern in ... Figure 4 The distance represented by D3 is contracted. Therefore, the distance represented by D4 is greater than the distance represented by D3, so the first weft yarn 111 in the three-dimensional patterned area 130a of the leno weave, in which the warp and weft yarns are arranged in a manner that can ensure the distance represented by D4, can contract more than the first weft yarn 111 in the unpatterned area 130b of the leno weave, so that the second weft yarn 112 can correspondingly protrude more towards the surface, thereby maximizing the effect of the three-dimensional pattern.

[0057] In another specific example, warp and weft yarns are arranged in the plain leno weave region 130b such that there is no second opening b between the first opening a and the other adjacent first opening a'. In the plain leno weave region 130b, the second weft yarn 112 arranged inside the upper does not need to protrude, so the first weft yarn 111, which is a high-elastic yarn, and the second weft yarn 112, which is a regular yarn, pass through the opening formed by the first warp yarn 113a and the second warp yarn 113b to achieve weaving, and the plain leno weave region 130b can be formed flat.

[0058] In another specific example, in the upper of a shoe according to another specific example of the present invention, the three-dimensional patterned area includes a basic weave three-dimensional patterned area woven with a basic weave and a gauze weave three-dimensional patterned area woven with a gauze weave, and the patternless area includes a basic weave patternless area woven with a basic weave and a gauze weave patternless area woven with a gauze weave.
