A fabric and a method of making the same

Abstract

The application discloses a fabric and a preparation method thereof. The fabric comprises at least a first weaving area and a second weaving area. The first weaving area is interwoven by warp yarns and weft yarns according to a two-over weft weave. The second weaving area is interwoven by warp yarns and weft yarns according to a single-layer change warp weave. The weft yarns of the surface layer of the first weaving area are surface layer weft yarns. The weft yarns of the inner layer of the first weaving area are inner layer weft yarns. The shrinkage rate of the surface layer weft yarns is less than that of the inner layer weft yarns. The shrinkage rate of the surface layer weft yarns of the two-over weft weave is less than that of the inner layer weft yarns. Because the shrinkage rate of the surface layer weft yarns is low and the shrinkage rate of the inner layer weft yarns is high, the shrinkage amount of the inner layer weft yarns is large and the shrinkage amount of the surface layer weft yarns is small after the fabric is shaped at high temperature. Therefore, the surface layer weft yarns are longer than the inner layer weft yarns and are forced to bow and present a convex state. After the surface layer weft yarns are convex, the fabric presents a three-dimensional effect.

Description

Technical Field

[0001] The present invention relates to the field of weaving technology, in particular to a fabric and a preparation method thereof. Background Art

[0002] As people's living standards improve, new requirements are being placed on the surface of shoe upper fabrics. These fabrics are not only required to be strong and comfortable, but also to have a three-dimensional effect. However, existing woven shoe fabrics are usually flat and lack a three-dimensional effect.

[0003] Therefore, how to make fabrics have a three-dimensional effect is a technical problem that those skilled in the art currently need to solve. Summary of the Invention

[0004] In view of this, the object of the present invention is to provide a fabric so that the fabric has a three-dimensional effect;

[0005] Another object of the present invention is to provide a method for preparing the above-mentioned fabric.

[0006] In order to achieve the above object, the present invention provides the following technical solutions:

[0007] A fabric comprising at least a first weaving area and a second weaving area, wherein the first weaving area is formed by interweaving warp yarns and weft yarns in a double weft weave, and the second weaving area is formed by interweaving warp yarns and weft yarns in a single-layer variable warp weight plain weave;

[0008] The weft yarn of the surface layer tissue of the first weaving area is the surface weft yarn, and the weft yarn of the inner layer tissue of the first weaving area is the inner weft yarn. The shrinkage rate of the surface weft yarn is smaller than the shrinkage rate of the inner weft yarn.

[0009] Optionally, in the above fabric, the surface weft yarn is thicker than the inner weft yarn.

[0010] Optionally, in the above fabric, the picking ratio of the inner layer weft yarn to the surface layer weft yarn is 2:1, and the surface layer structure of the first weaving area is a full down structure, and the inner layer structure of the first weaving area is a 1 / 1 plain weave.

[0011] Optionally, in the above-mentioned fabric, the weft yarn of the second weft area includes a first weft yarn and a second weft yarn, wherein the shuttle ratio of the first weft yarn and the second weft yarn is 2:1, the weft structure formed by the first weft yarn and the warp yarn is a 1 / 1 plain weave, and the weft structure formed by the second weft yarn and the warp yarn is a half-shuttle plain weave, so that the second weft area constitutes a two-up-one-down warp-weight plain weave.

[0012] Optionally, in the above fabric, the first weft yarn and the inner layer weft yarn are the same yarn, and the second weft yarn and the surface layer weft yarn are the same yarn.

[0013] Optionally, in the above fabric, the warp yarn, the first weft yarn and the inner weft yarn are all monofilaments, and the second weft yarn and the surface weft yarn are all multifilaments.

[0014] Optionally, in the above fabric, the warp yarn is nylon monofilament, the first weft yarn and the inner layer weft yarn are TPEE monofilament or TPU monofilament, and the second weft yarn and the surface layer weft yarn are nylon multifilament or polyester multifilament.

[0015] Optionally, in the above fabric, the first weft yarn and the inner weft yarn are 100D-200D TPU monofilament;

[0016] The second weft yarn and the surface weft yarn are 500D-700D polyester double-twisted colored yarn.

[0017] Optionally, in the above fabric, the area of ​​the first knitting area is smaller than the area of ​​the second knitting area, and the first knitting area is the pattern of the fabric.

[0018] The fabric provided by the present invention has a double-weave weave structure in the first weft region and a single-layer plain weave structure with variable warp weight in the second weft region. The shrinkage rate of the surface weft yarns in the double-weave weave is lower than that of the inner weft yarns. Because the shrinkage rate of the surface weft yarns is lower than that of the inner weft yarns, after the fabric is subjected to high-temperature setting, the inner weft yarns shrink more, while the surface weft yarns shrink less. This causes the surface weft yarns to be longer than the inner weft yarns and be forced to arch, presenting a convex state. This convexity of the surface weft yarns creates a three-dimensional effect on the fabric.

[0019] A method for preparing a fabric comprises the steps of:

[0020] Fabric weaving, weaving the fabric as described in any one of the items to obtain an initial fabric;

[0021] Fabric shaping: heating the initial fabric to a preset temperature to shape the initial fabric to obtain a finished fabric product.

[0022] The method for preparing the fabric provided by the present invention has the technical effects of the above-mentioned fabrics because it prepares the above-mentioned fabrics, and will not be described in detail herein. BRIEF DESCRIPTION OF THE DRAWINGS

Obviously, the drawings described below are only some embodiments of the present invention.

[0029] The core of the present invention is to provide a fabric so as to give the fabric a three-dimensional effect;

[0030] Another core of the present invention is to provide a method for preparing the above-mentioned fabric.

[0031] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0032] like Figure 1 As shown, the present invention discloses a fabric that can be used as a shoe upper fabric, clothing fabric, etc. The present invention does not limit the scope of application of the fabric. The fabric disclosed in this embodiment includes at least a first knitting area 100 and a second knitting area 200. The first knitting area 100 and the second knitting area 200 have different weave structures.

[0033] The first weave region 100 is formed by interweaving warp and weft yarns in a double weft weft pattern, while the second weave region 200 is formed by interweaving warp and weft yarns in a single layer, variable warp weight plain weave pattern. That is, the weave structure of the second weave region 200 is a variable warp weight plain weave and a single layer weave. The weft yarns of the surface weft of the first weave region 100 are surface weft yarns, while the weft yarns of the inner weft of the first weave region 100 are inner weft yarns. The shrinkage rate of the surface weft yarns is lower than that of the inner weft yarns. In this embodiment, different yarns are selected for the inner and surface weft yarns, resulting in different shrinkage rates for the inner and surface weft yarns, thereby creating a three-dimensional effect. The greater the difference in shrinkage rate between the inner and surface weft yarns, the stronger the three-dimensional effect.

[0034] Double plain weave refers to a weave formed by extending the weave points along the warp (or weft) yarn direction based on the plain weave.

[0035] The warp-weight plain weave is based on the plain weave and is formed by extending the weave points along the warp direction.

[0036] Variable warp weight plain weave means that the weave points are extended along the warp direction, and the warp float length is a variable;

[0037] The double weft structure refers to the overlapping and covering of the weft yarns of the surface and lining systems in the fabric. Its arrangement ratio, interweaving, surface and lining structures are similar to the double warp structure, except that the warp and weft are interchanged.

[0038] In summary, the fabric provided by the present invention has a double-weft weave structure in the first weft region 100 and a single-layer plain weave structure with variable warp weight in the second weft region 200. The shrinkage rate of the surface weft yarn in the double-weft weave is lower than that of the inner weft yarn. Because the shrinkage rate of the surface weft yarn is lower and that of the inner weft yarn is higher, after the fabric undergoes high-temperature setting, the inner weft yarn shrinks more, while the surface weft yarn shrinks less. Due to the difference in shrinkage between the two weft yarns after the high-temperature setting process, the surface weft yarn is longer than the inner weft yarn and is forced to arch, presenting a convex state. This convexity of the surface weft yarn gives the fabric a three-dimensional effect.

[0039] The fabric disclosed in the embodiment of the present invention is a woven fabric, which adopts a fabric structure that combines a double weft structure and a single-layer variable warp plain structure, so that the surface of the fabric on one side has a texture structure with a strong three-dimensional sense, thereby allowing the prepared shoe material fabric to have different appearance effects and wearing comfort.

[0040] To further enhance the three-dimensional effect on one side of the fabric, in this embodiment, the surface weft yarn is designed to be thicker than the inner weft yarn. Because the surface weft yarn shrinks less than the inner weft yarn and is thicker than the inner weft yarn, it curves and creates a raised effect after the inner weft yarn shrinks. In this embodiment, the raised surface weft yarn is thicker, meaning the difference in thickness between the surface and inner weft yarns is significant, creating a more three-dimensional effect.

[0041] In a specific embodiment of the present invention, the shuttle ratio of the inner weft yarn and the surface weft yarn is 2:1, the inner weft yarn is inserted into 2 strands, and the surface weft yarn is inserted into 1 strand. The specific arrangement method can be the inner weft yarn, the inner weft yarn, the surface weft yarn, the inner weft yarn, the surface weft yarn, the inner weft yarn, the surface weft yarn, the inner weft yarn, the inner weft yarn. The specific method to be adopted can be selected by technical personnel in this field according to needs.

[0042] The surface weave of the first weaving area 100 is a full-down weave, meaning the warp and surface weft yarns are not interwoven to form floating weft yarns. The back weave of the first weaving area 100 is a 1 / 1 plain weave. A full-down weave differs from a 1 / 1 plain weave in that all warp yarns are not raised. In a 1 / 1 plain weave, one weft yarn is raised while the other is not. A plain weave is a basic weave in which the warp and weft yarns alternate in a 1:1 ratio. This weave is formed by alternating warp and weft yarns, one above the other. This means that the warp and weft yarns alternately float and sink in a counterclockwise fashion, creating a fabric structure in which the warp and weft yarns alternately float and sink in a counterclockwise fashion.

[0043] Furthermore, in this embodiment, the area of ​​the first knitting area 100 is smaller than the area of ​​the second knitting area 200, and the first knitting area 100 is a pattern of the fabric. Those skilled in the art can design the shape of the first knitting area 100 according to actual needs, and the shape of the first knitting area 100 is not limited to Figure 1 The pattern shown.

[0044] Since the first weaving area is smaller and the floating length of the surface weft yarn is shorter, and the thickness of the surface weft yarn and the inner weft yarn are quite different, the three-dimensional effect of the raised surface weft yarn is further enhanced.

[0045] like Figure 2 As shown, in a specific embodiment of the present invention, the weft yarns of the second weft area 200 include a first weft yarn and a second weft yarn, wherein the picking ratio of the first weft yarn and the second weft yarn is 2:1. Figure 2 In the illustrated solution, two first weft yarns and one second weft yarn are arranged in the manner of first weft yarn, first weft yarn, second weft yarn.

[0046] Figure 2 From the structure at A in the figure, we can see that the structure formed by the first weft yarn and the warp yarn is a 1 / 1 plain weave. Figure 2 From the structure at B in the middle, it can be seen that the second weft yarn and the warp yarn cannot form a complete 1 / 1 plain weave, but can only form half of the 1 / 1 plain weave, which is called a half-shuttle plain weave, so that the second weaving area 200 constitutes a two-up-one-down warp-weight plain weave.

[0047] In this embodiment, the first and second weft yarns can partially form a plain weave with a common weft. During high-temperature setting, the first and second weft yarns mutually influence each other's shrinkage, and the weft yarn floats are minimized, resulting in a plain weave with a minimal weft length. Ultimately, the first and second weft yarns shrink in close alignment, resulting in a smooth finish.

[0048] In this embodiment, the first weft yarn and the inner weft yarn are the same yarn, and the second weft yarn and the outer weft yarn are the same yarn. Specifically, the warp yarn, the first weft yarn and the inner weft yarn are all monofilaments, and the second weft yarn and the outer weft yarn are all multifilaments.

[0049] After high-temperature setting, the reverse side of the fabric exhibits uniform shrinkage, as each shed contains monofilaments. Consequently, all yarns on the reverse side interweave on the same plane, resulting in a relatively smooth reverse side. Furthermore, since each shuttle of weft yarn exhibits a high degree of expansion and contraction, the fabric exhibits a slight degree of elasticity after high-temperature setting, perfectly meeting the elasticity requirements of shoe fabrics.

[0050] The fabric disclosed in the embodiments of the present invention utilizes a fabric structure that combines a double-weft weave with a single-layer, variable-weight plain weave, resulting in a three-dimensional textured woven fabric, enhancing both the appearance and comfort of the shoe. This three-dimensional textured fabric exhibits a slightly elastic, spatial texture, resulting in point contact with the skin. Combined with the wrapping properties of the slightly elastic texture, this improves wearing comfort, effectively channeling sweat and preventing adhesion to the skin's surface.

[0051] Furthermore, in this embodiment, the warp yarn of the fabric can be nylon monofilament, and the first weft yarn and the inner weft yarn can be TPEE (thermoplastic polyester elastomer) monofilament or TPU (thermoplastic polyurethane elastomer) monofilament. It should be noted that the first weft yarn and the inner weft yarn can be any high-shrinkage monofilament and are not limited to the two examples listed above.

[0052] The second weft yarn and the surface weft yarn are nylon multifilament or polyester multifilament. It should be noted that the second weft yarn and the surface weft yarn can be any multifilament and are not limited to the two examples listed above.

[0053] Furthermore, the first weft yarn and the inner weft yarn can be 100D-200D TPU monofilament, such as 150D TPU single-color yarn; the second weft yarn and the surface weft yarn can be 500D-700D polyester double-twisted colored yarn, such as 600D / 192F polyester double-twisted colored yarn.

[0054] The present invention discloses a method for preparing a fabric, comprising a fabric weaving step and a fabric shaping step. The fabric weaving step comprises weaving the fabric disclosed in the above embodiment to obtain an initial fabric. It should be noted that after the fabric structure disclosed in the above embodiment, a fabric having the aforementioned structure can be woven using conventional weaving methods to obtain an initial fabric.

[0055] The fabric setting step involves heating the initial fabric to a preset temperature to set the initial fabric and obtain the finished fabric. It should be noted that the setting temperature (i.e., the preset temperature) in the fabric setting step should be selected based on the yarn used in the fabric. Typically, the preset temperature can be set between 160°C and 200°C. For the fabric disclosed in the embodiments of the present invention, the preset temperature can be set at 180°C.

[0056] The present invention further discloses a pair of shoes comprising the fabric disclosed in the above embodiment. The shoes disclosed in the present invention, because they comprise the above fabric, have all the technical effects of the above fabric, which will not be described in detail herein.

[0057] It should be noted that the various embodiments in this specification are described in a progressive manner, and each embodiment focuses on the differences from other embodiments. The same and similar parts between the various embodiments can be referenced to each other.
