AI Technical Summary
Traditional denim fabrics have too many seams in their multi-layered structure, resulting in a high rate of weaving breakage, low production efficiency, and an unclear twill pattern on the fabric surface; too few seams result in loose connections between the upper and lower layers, making them prone to separation.
The surface layer is formed by interlacing the first warp and the first weft, and the bottom layer is formed by interlacing the second warp and the second weft. The radial cross-sectional area of the first warp and the weft is relatively large, and the number of joints is limited. Moreover, the number of warp weave points formed by the first warp in the surface layer is more than twice that of the second weft. The interlacing method is three-up-one-down twill and one-up-one-down plain weave, which hides the joints.
It achieves the ability for the surface layer to easily cover the bottom layer, the bottom layer to be less likely to detach, the joints to have little impact on the texture of the surface layer, high production efficiency and stable fabric quality.

Abstract
Description
Technical Field
[0001] This utility model relates to a patterned denim fabric, belonging to the textile field. Background Technology
[0002] Traditional denim fabric is woven from warp and weft yarns. The warp yarns are made of pure cotton yarn dyed with indigo, while the weft yarns are made of off-white pure cotton yarn. Traditional denim fabric is favored for its tightness, thickness, and durability, and after more than a century of development, it has remained a staple in the fashion world, holding an irreplaceable position in the clothing market. With social progress and economic development, single-structure fabrics can no longer meet market demands, leading to the emergence of double-layered denim fabrics. Denim garments made from double-layered denim fabrics have gradually gained popularity. Double-layered denim fabrics create different effects by using different structures on the upper and lower layers. Typically, the upper layer exhibits the texture of traditional denim fabric, while the lower layer utilizes a different fabric structure to improve the tactile feel (hand feel) of the fabric.
[0003] When constructing multi-layered fabric structures, connection points are needed to link the upper and lower layers. These points are formed by the occasional interlacing of warp yarns in the upper layer with weft yarns in the lower layer, or vice versa. Generally, one or two connection points are set within a minimum weave repeat. Too many connection points will result in a high weave breakage rate, low production efficiency, and numerous quality defects. Furthermore, too many connection points will affect the twill pattern of the fabric and make the texture unclear. If too few connection points are set, the connection between the upper and lower layers will be weak, and the layers will easily separate. Utility Model Content
[0004] In order to overcome the shortcomings of the existing technology, this utility model provides a fancy denim fabric in which the seams do not easily affect the fabric texture on the front of the surface layer, and the surface layer and the bottom layer are not easily separated.
[0005] The technical solution adopted by this utility model to solve its technical problem is:
[0006] A patterned denim fabric includes an outer layer woven from a first warp and a first weft, and an inner layer woven from a second warp and a second weft. The radial cross-sectional area of the first warp is at least 1.5 times that of the second warp, and the radial cross-sectional area of the first weft is at least 1.5 times that of the second weft. The number of knots is at most one within one minimum weave cycle and at least one within three consecutive minimum weave cycles. In the minimum weave cycle, the number of warp knots formed by the first warp in the outer layer is at least twice the number of weft knots formed by the second weft in the inner layer.
[0007] The fancy denim fabric provided in this application has a first warp yarn that is thicker than the second warp yarn that is thicker than the second weft yarn that is thicker than the second weft yarn that is thicker than the second weft yarn that is thicker than the second weft yarn that is thicker than the second weft yarn that is thicker than the third weft yarn. The surface layer can easily cover the bottom layer. The bottom layer is woven with finer yarns and is thinner than the surface layer. With fewer knots, the bottom layer can be "hung" under the surface layer, and the surface layer and the bottom layer are not easy to separate. With fewer knots and the yarns that form the knots in the bottom layer are finer yarns, and the number of warp points formed by the first warp yarn in the surface layer is more than twice the number of weft points formed by the second weft yarn in the bottom layer, the knots have minimal impact on the fabric texture of the front of the surface layer.
[0008] Furthermore, the first warp yarn and the first weft yarn are interwoven in a three-up-one-down twill weave, while the second warp yarn and the second weft yarn are interwoven in a one-up-one-down plain weave. The second warp yarn and the second weft yarn interweave to form a tight and strong plain weave structure, which makes the thin bottom layer less prone to delamination even with fewer joints. The first warp yarn and the first weft yarn can interweave to form a twill weave similar to that of traditional denim fabric.
[0009] Furthermore, the joining point is the warp weave point formed by the overlap of the second warp yarn and the first weft yarn, which is more conducive to visually hiding the joining point from the front of the surface layer.
[0010] Furthermore, the radial cross-sectional area of the first warp yarn is 2 to 10 times that of the radial cross-sectional area of the second warp yarn.
[0011] In some embodiments, the first warp yarn is 6S to 16S cotton yarn.
[0012] Furthermore, the second warp yarn is a 32S~60S cotton yarn.
[0013] Alternatively, the second warp yarn is a 75D~300D synthetic filament.
[0014] Furthermore, the radial cross-sectional area of the first weft yarn is 2 to 10 times that of the radial cross-sectional area of the second weft yarn.
[0015] In some embodiments, the first weft yarn is a 6S to 16S elastic yarn. The elastic first weft yarn can tighten the structure of the surface layer, making the surface layer more compact and providing stronger coverage to the underlying layer.
[0016] Furthermore, the second weft yarn is a 75D~300D synthetic filament.
[0017] The beneficial effects of this utility model are as follows: In this utility model, the first warp yarn participating in the formation of the surface layer of the fancy denim fabric is thicker than the second warp yarn participating in the formation of the bottom layer, and the first weft yarn participating in the formation of the surface layer is thicker than the second weft yarn participating in the formation of the bottom layer. The surface layer can easily cover the yarns of the bottom layer. The bottom layer is woven with finer yarns and is lighter and thinner than the surface layer. Fewer knots are needed to prevent the surface layer and the bottom layer from delaminating. With fewer knots and the yarns participating in forming the knots in the bottom layer being finer yarns, and the number of warp weft points formed by the first warp yarn in the surface layer being more than the number of weft weft points formed by the second weft yarn in the bottom layer, the knots are less likely to affect the fabric texture style on the front of the surface layer.

[0027] Unless otherwise specified, all technical and scientific terms used herein have the standard meaning in the field to which the claimed subject matter pertains. Where multiple definitions exist for a term, the definition herein shall prevail.
[0028] This application provides a fancy denim fabric, including a surface layer woven from a first warp and a first weft, and a bottom layer woven from a second warp and a second weft. The radial cross-sectional area of the first warp is more than 1.5 times that of the second warp, and the radial cross-sectional area of the first weft is more than 1.5 times that of the second weft. The number of knots is at most one within one minimum weave cycle and at least one within three consecutive minimum weave cycles. In the minimum weave cycle, the number of warp knots formed by the first warp on the surface layer is more than twice the number of weft knots formed by the second weft on the bottom layer.
[0029] This type of double-layer denim fabric has the following advantages:
[0030] (1) The first warp yarn that forms the surface layer is thicker than the second warp yarn that forms the bottom layer, and the first weft yarn that forms the surface layer is thicker than the second weft yarn that forms the bottom layer. Therefore, the surface layer can easily cover the bottom layer.
[0031] (2) The bottom layer is woven with finer yarns. The bottom layer is lighter and thinner than the top layer. The top and bottom layers are not easy to separate. With fewer joints, the bottom layer can be "hung" under the top layer.
[0032] (3) Fewer knots and the yarns involved in forming knots at the bottom layer are finer yarns, making it difficult to see the knots on the front of the surface layer; at the same time, the number of warp points formed by the first warp yarn on the surface layer is more than twice the number of weft points formed by the second weft yarn at the bottom layer, which is conducive to forming knots by overlapping the first weft yarn and the second warp yarn. Such knots have little impact on the fabric texture style on the front of the surface layer.
[0033] A specific embodiment can be referred to. Figure 1 , Figure 1 This is the minimum weave repeat for this fabric. Columns represented by uppercase letters represent the first warp yarn, and columns represented by lowercase letters represent the second warp yarn. Rows represented by odd-numbered Arabic numerals represent the first weft yarn, and rows represented by even-numbered Arabic numerals represent the second weft yarn. Unfilled squares indicate that the weft yarn is on top of the warp yarn, while filled squares indicate that the warp yarn is on top of the weft yarn. The first warp and first weft yarns are interwoven in a 3-up-1-down twill weave, and the second warp and second weft yarns are interwoven in a 1-up-1-down plain weave. The number of warp weave points formed by the first warp yarn on the surface layer is three times the number of weft weave points formed by the second weft yarn on the bottom layer. The second warp yarn in column h overlaps with the first weft yarn in row 23 to form a warp weave point, which serves as the junction point in this minimum weave repeat.
[0034] To better understand the organizational structure of the top and bottom layers, please refer to... Figure 2 , Figure 2 and Figure 1 These represent the same embodiment, only with different representations. Figure 2The middle section has multiple rows of first warp yarns arranged together, and multiple rows of second warp yarns arranged together, making it easier to see that the surface layer is twill and the bottom layer is plain.
[0035] In another embodiment, please refer to Figure 3 In the vertical axis, odd-numbered Arabic numerals represent the first weft yarn, and even-numbered Arabic numerals represent the second weft yarn. Odd-numbered Arabic numerals on the horizontal axis represent the first warp yarn, and even-numbered Arabic numerals represent the second warp yarn. Unfilled cells indicate the weft yarn is on the warp yarn, while filled cells indicate the warp yarn is on the weft yarn. The first warp and first weft yarns are interwoven in a 3-up-1-down twill weave, and the second warp and second weft yarns are interwoven in a 1-up-1-down plain weave. The number of warp weft points formed by the first warp yarn on the surface layer is three times the number of weft weft points formed by the second weft yarn on the bottom layer. That is, ignoring knots, the minimum weave repeat is... Figure 1 The embodiments shown are the same, the difference being that, Figure 3 In a representative embodiment, a junction point is set only every three minimum weave cycles, that is, the second warp yarn in column 32 and the first weft yarn in row 35 overlap to form a warp weave point as a junction point.
[0036] In the two embodiments described above, preferably, the second warp yarn is finer than both the first warp yarn and the first weft yarn, and the second weft yarn is finer than both the first warp yarn and the first weft yarn. Specifically, the first warp yarn can be 6S~16S cotton yarn, and the second warp yarn can be 32S~60S cotton yarn or 75D~300D synthetic fiber filament. The first weft yarn can be 6S~16S cotton yarn, and the second warp yarn can be 32S~60S cotton yarn or 75D~300D synthetic fiber filament.
[0037] More preferably, the first weft yarn is a 6S~16S elastic yarn. When the elastic first weft yarn interweaves with the second warp yarn to form a joint, the joint is less likely to break, the surface layer and the bottom layer are less likely to come apart, and the elastic first weft yarn can tighten the structure of the surface layer, making the surface layer more compact and the surface layer has a stronger covering effect on the bottom layer, which is more conducive to visually hiding the joint from the front of the surface layer.
[0038] In the description of this specification, the references to terms such as "one embodiment," "some embodiments," "illustrative embodiment," "example," "specific example," or "some examples," etc., indicate that a specific feature, structure, material, or characteristic described in connection with the embodiment or example is included in at least one embodiment or example of this utility model. In this specification, the illustrative expressions of the above terms do not necessarily refer to the same embodiment or example. Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples.
[0039] The above description is the preferred embodiment of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications are also considered to be within the protection scope of this utility model.
