Description

Technical Field

[0001] This utility model belongs to the textile field, specifically relating to a multi-layer jacquard fabric for clothing and a down jacket. Background Technology

[0002] Existing fabrics, such as those used in down jackets, are mainly double-layered. The problems with double-layered fabrics are: (See...) Figure 12 In double-layered fabrics, the upper and lower layers are directly interwoven, creating multiple interlacing points. When insulating filler is added between the upper and lower layers, it cannot be filled at the interlacing points. This results in an uneven surface between the upper and lower layers, making both layers rough. Furthermore, the lack of insulating filler at these points allows cold wind to penetrate, and the insulating filler can easily escape through them, severely impacting the garment's warmth, product quality, and lifespan. Additionally, the marks left at the interlacing points result in a poor feel and user experience. The dyeing at the interlacing points also differs from other areas, leading to an overall unattractive appearance and failing to achieve both warmth and aesthetics. Utility Model Content

[0003] The purpose of this invention is to provide a multi-layer jacquard fabric for clothing and down jackets, which overcomes the cold bridging phenomenon of double-layer fabrics compared to double-layer fabrics; the fabric has high down-proof properties and good warmth retention.

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

[0006] The inner connection point, the first outer connection point, and the second outer connection point do not refer to a single point, but rather to multiple tissue points at the connection point that present a linear structure along the second extension direction, such as a straight line or a curve.

[0013] For the second outer connection point formed by the connection between the second inner fabric layer and the second outer fabric layer, the weft yarn at the second outer connection point is formed by the interlacing of the warp yarns of the second inner fabric layer and the weft yarns at the corresponding junction of the second outer fabric layer, and the warp yarn forming the weft yarn at the second outer connection point is pressed between the warp and weft yarns at the corresponding position of the weft yarn at the second outer fabric layer; or the weft yarn at the second outer connection point is formed by the interlacing of the weft yarns of the second inner fabric layer and the warp yarns at the corresponding junction of the second outer fabric layer, and the weft yarn forming the weft yarn at the second outer connection point is pressed between the warp and weft yarns at the corresponding position of the weft yarn at the second outer fabric layer.

Preferably, based on the width and fabric weight, the total number of the plurality of inner connection points, the plurality of first outer connection points, and the plurality of second outer connection points are 4 to 25 per meter.

[0029] According to some embodiments of the present invention, the first outer connecting point and the second outer connecting point correspond one-to-one. Preferably, the first outer connecting point and the corresponding second outer connecting point are directly opposite each other in the fabric thickness direction.

[0030] According to some embodiments of this utility model, the heights of the plurality of inner connection points at the corresponding positions of the fabric thickness are the same or different. Preferably, the inner connection points are located at positions of 1 / 10 to 9 / 10 of the fabric thickness. More preferably, the inner connection points are located at positions of 1 / 2 of the fabric thickness.

[0031] According to some embodiments of this utility model, along the first extending direction, the plurality of storage channels constitute a plurality of storage units, each of the storage units including an adjacent but relatively independent first storage channel, a second storage channel and a third storage channel. The first storage channel and the second storage channel are distributed along the thickness direction of the fabric, and the third storage channel is located on the same side of the first storage channel and the second storage channel. When the fabric is in use, the cross-sections of the first storage channel and the second storage channel are triangular, and the cross-section of the third storage channel is quadrilateral.

[0032] Preferably, the first storage channel and the second storage channel are both isosceles triangles; the third storage channel has a square or rectangular cross-section.

[0033] Preferably, the fabric has a symmetrical structure along the fabric thickness direction, the first extension direction, and the second extension direction. In this case, the first storage channel and the second storage channel are both isosceles triangles, and the cross-section of the third storage channel is square or rectangular.

[0034] In some embodiments, the fabric has a symmetrical structure along both the first and second extension directions.

[0035] In some embodiments, the fabric has a symmetrical structure along the fabric thickness direction.

[0036] In some embodiments, the fabric has an asymmetrical structure along the fabric thickness direction, the first extension direction, and the second extension direction.

[0037] In some embodiments, the first extension direction is perpendicular to the second extension direction.

[0038] According to some embodiments of this utility model, the warp density of the first outer fabric layer and the second outer fabric layer is greater than or equal to the warp density of the first inner fabric layer and the second inner fabric layer, and the weft density of the first outer fabric layer and the second outer fabric layer is greater than or equal to the weft density of the first inner fabric layer and the second inner fabric layer. Preferably, the warp density of the first outer fabric layer and the second outer fabric layer is greater than the warp density of the first inner fabric layer and the second inner fabric layer, which can reduce the overall weight.

[0039] According to some embodiments of this utility model, the warp density of the first outer fabric layer, the second outer fabric layer, the first inner fabric layer, and the second inner fabric layer is 20-150 threads / 10cm, and the weft density of the first outer fabric layer, the second outer fabric layer, the first inner fabric layer, and the second inner fabric layer is 20-150 threads / 10cm.

[0040] Preferably, the warp density of the first outer fabric layer and the second outer fabric layer are both 60-100 threads / 10cm, and the weft density of the first outer fabric layer and the second outer fabric layer are both 60-100 threads / 10cm; the warp density of the first inner fabric layer and the second inner fabric layer are both 30-50 threads / 10cm, and the weft density of the first inner fabric layer and the second inner fabric layer are both 30-50 threads / 10cm.

[0041] According to some embodiments of this utility model, when in use, the distance between the first outer fabric layer and the second outer fabric layer is greater than or equal to 1 cm and less than or equal to 5 cm.

[0042] Furthermore, the fabric also includes a third inner fabric layer, which is arranged intersectingly with the first inner fabric layer and / or the second inner fabric layer in the thickness direction of the fabric. The two outer sides of the third inner fabric layer are connected to the first outer fabric layer and the second outer fabric layer, respectively. The middle portion of the third inner fabric layer is connected to the first inner fabric layer and / or the second inner fabric layer to form multiple inner connection points. The third inner fabric layer is also connected to the first outer fabric layer and the second outer fabric layer to form multiple third outer connection points. Each of the multiple inner connection points, the multiple first outer connection points, the multiple second outer connection points, and the multiple third outer connection points is distributed along the first extension direction, thereby forming multiple storage channels extending along the second extension direction on the fabric. Adding a third inner fabric layer increases the number of storage channels. When filled with filler, while ensuring the outer surface of the fabric is flat, it can better contain the filler, preventing it from escaping, resulting in better down-proof properties of the garment.

[0043] The third inner fabric layer includes multiple segments continuously and sequentially arranged along the first extending direction. The multiple segments include a first segment, multiple intermediate segments, and a second segment. The first segment and the second segment are located at opposite ends of the multiple intermediate segments. One outer side of the first segment is connected to the second outer fabric layer, and the other outer side of the first segment and one outer side of the adjacent intermediate segment are jointly connected to the first outer fabric layer. One outer side of the second segment is connected to the first outer fabric layer, and the other outer side of the second segment and one outer side of the adjacent intermediate segment are jointly connected to the second outer fabric layer. The two outer sides of the intermediate segments are respectively connected to the first outer fabric layer and the second outer fabric layer.

[0044] The third outer connection point formed by the connection of one outer side of the first segment and the second outer fabric layer maintains a distance from the adjacent second outer connection point. Similarly, the third inner connection point formed by the connection of the other outer side of the first segment and the outer side of the adjacent middle segment to the first outer fabric layer maintains a distance from the adjacent first outer connection point. Likewise, the connection of one outer side of the second segment to the first outer fabric layer maintains a distance from the adjacent first outer connection point. The third inner connection point formed by the connection of the other outer side of the second segment and the outer side of the adjacent middle segment to the second outer fabric layer maintains a distance from the adjacent second outer connection point. By setting the first and second segments, when the fabric is in use, the first and second outer fabric layers can be better stretched apart, resulting in smoother surfaces for both layers. Simultaneously, the increased number of storage channels improves down-proof properties.

[0045] In some implementations, the number of multiple third outer connection points is greater than or equal to the number of multiple first outer connection points, and the number of multiple third outer connection points is greater than or equal to the number of multiple second outer connection points.

[0046] In some embodiments, the filling material in the storage channel is one or more combinations of down, cotton, and wool.

[0047] This utility model also provides a down jacket, wherein at least a portion of the down jacket is made of the aforementioned garment fabric.

[0048] The multi-layer jacquard fabric for clothing of this utility model includes, but is not limited to, clothing, home textiles, and inflatable products. Home textiles include, but are not limited to, down comforters and curtains. The multi-layer jacquard fabric for clothing of this utility model is preferably used for clothing.

[0049] Due to the application of the above technical solution, this utility model has the following advantages compared with the prior art:

[0050] This utility model provides a multi-layered jacquard fabric for clothing. The first inner fabric layer is connected to one or both of the first outer fabric layer and the second outer fabric layer. The second inner fabric layer is also connected to one or both of the first and second outer fabric layers. The connections do not disrupt the structural organization of the first and second outer fabric layers. When used to make garment filling, the outer surfaces of the first and second outer fabric layers remain smooth and even, resulting in uniform dyeing. The filling will not leak out from the connections, and the connections will not be penetrated by cold wind, providing insulation. It has high pile quality; and combined with the connection between the middle of the first inner fabric layer and the middle of the second inner fabric layer, the multiple storage channels formed on the fabric are not only structurally stable, but also better able to limit the filling material, making it less likely for the internal filling material to leak out. It can also better distribute the filling material, resulting in a more uniform distribution of the filling material, good product quality stability, and further improved product warmth retention and other properties. Compared with double-layer fabrics, it overcomes the cold bridging phenomenon of double-layer fabrics. Because the outer surfaces of the first outer fabric layer and the second outer fabric layer are flat, it is easier to achieve a consistent thickness, density, and hand feel throughout the outer surface of the fabric.

[0051] The down jacket provided by this utility model has high down-proof properties, good warmth retention, and a smooth outer surface after filling. Based on this, a more uniform dyeing effect can be obtained, and different graphic styles can be displayed. Attached Figure Description

Detailed Implementation

[0066] The present invention will be further described below with reference to the embodiments shown in the accompanying drawings.

[0067] Example 1

[0068] See Figures 1-6 The first inner fabric layer 2 and the second inner fabric layer 3 are arranged in a cross direction in the thickness direction of the fabric. The first inner fabric layer 2 is continuously arranged, and the second inner fabric layer 3 is continuously arranged. The two outer sides of the first inner fabric layer 2 are connected to the first outer fabric layer 1 and the second outer fabric layer 4 respectively to form a plurality of first outer connection points 5. The two outer sides of the second inner fabric layer 3 are connected to the first outer fabric layer 1 and the second outer fabric layer 4 respectively to form a plurality of second outer connection points 6. The middle part of the first inner fabric layer 2 is connected to the middle part of the second inner fabric layer 3 to form a plurality of inner connection points 7. Here, the middle part does not only refer to the very center position, but refers to the position of the first inner fabric layer 2 and the second inner fabric layer 3 other than the outer side.

[0069] In the usage state, the first inner fabric layer 2 forms multiple segments similar to Figures 1-6 The zigzag shape shown is formed by multiple segments of the second inner fabric layer 3. Figures 1-6 The diagram shows a broken line shape.

[0070] In this example, the first storage channel 8a, the second storage channel 8b, and the third storage channel 8c constitute a storage unit, and the storage unit is repeatedly arranged along the first extension direction. At one end of the fabric, only the first storage channel 8a and the second storage channel 8b are provided.

[0071] In a preferred embodiment of this example, multiple inner connection points 7, multiple first outer connection points 5, and multiple second outer connection points 6 are each uniformly distributed along a first extending direction. The first outer connection points 5 and their corresponding second outer connection points 6 are directly opposite each other in the fabric thickness direction. On the first outer fabric layer 1, the first outer connection points 5 and second outer connection points 6 are arranged adjacent to each other, with equal spacing between each adjacent first outer connection point 5 and second outer connection point 6. On the second outer fabric layer 4, the first outer connection points 5 and second outer connection points 6 are arranged adjacent to each other, with equal spacing between each adjacent first outer connection point 5 and second outer connection point 6. In use, the inner connection points 7 are located at 1 / 2 of the fabric thickness; the first storage channel 8a and the second storage channel 8b are both isosceles triangles; the third storage channel 8c has a square or rectangular cross-section.

[0072] In this example, on the first outer fabric layer 1, a first outer connection point 5 has a first distance a1 between it and an adjacent second outer connection point 6, and a second distance a2 between the second outer connection point 6 and another adjacent first outer connection point 5. Correspondingly, on the second outer fabric layer 4, a second outer connection point 6 has a first distance b1 between it and an adjacent first outer connection point 5, and a second distance b2 between the first outer connection point 5 and another adjacent second outer connection point 6, satisfying a1 + a2 = b1 + b2. One implementation method is as follows: See [link to implementation details]. Figure 1 a1, a2, b1, and b2 are all equal; another implementation method is: see Figure 2 a1 equals b1, a2 equals b2, a1 does not equal a2; another implementation method is: see Figure 3 and Figure 4 a1 equals b2, a2 ​​equals b1, a1 does not equal a2; another implementation method is: see Figure 5 b1 equals b2, a1 and a2 are not equal; another implementation method is: see Figure 6 a1 equals a2, b1 does not equal b2, a1+a2=b1+b2.

[0073] More preferably, see Figure 1The first outer connecting point 5 and the corresponding second outer connecting point 6 are directly opposite each other in the fabric thickness direction, and a1, a2, b1, and b2 are all equal. The inner connecting point 7 is located at 1 / 2 of the fabric thickness (the distance between the inner connecting point 7 and the first outer fabric layer 1 is equal to the distance between the inner connecting point 7 and the second outer fabric layer 4). The density of the first outer fabric layer 1 and the second outer fabric layer 4 is consistent. More preferably, when in use, the first storage channel 8a and the second storage channel 8b are both isosceles right triangles, and the distance H between the first outer fabric layer 1 and the second outer fabric layer 4 is H = a1 / 2.

[0074] In the different embodiments described above, the outer surfaces of the first outer fabric layer 1 and the second outer fabric layer 4 present different patterns, which will present different styles after being made into clothing or textiles. The forms are varied and rich, meeting different needs.

[0075] Example 2

[0076] The difference between this example and Example 1 is as follows: See Figure 7 The fabric also includes a third inner fabric layer 10, which is provided once. The two outer sides of the third inner fabric layer 10 are connected to the first outer fabric layer 1 and the second outer fabric layer 4 respectively to form a plurality of third outer connection points 12. The middle part of the third inner fabric layer 10 is connected to the first inner fabric layer 2 and / or the second outer fabric layer 4 to form a plurality of inner connection points 7.

[0077] In this example, in the usage state, the third inner fabric layer 10 includes multiple segments that are continuously and sequentially arranged along the first extension direction. When the fabric is in use, the multiple segments are in a zigzag shape, with adjacent segments forming a V-shape. The longitudinal section of each segment is linear. At least one segment is connected to both the first inner fabric layer 2 and the second inner fabric layer 3, at least one segment is connected only to the first inner fabric layer 2, and at least one segment is connected only to the second inner fabric layer 3. Multiple inner connection points 7, multiple first outer connection points 5, multiple second outer connection points 6, and multiple third outer connection points 12 are each distributed along the first extension direction, thereby forming multiple storage channels extending along the second extension direction on the fabric.

[0078] See Figure 7The third inner fabric layer 10 includes multiple segments, including a first segment 10b, a middle segment 10c, and a second segment 10d. The first segment 10b and the second segment 10d are located at opposite ends of the multiple middle segments 10c. One outer side (one end) of the first segment 10b is connected to the second outer fabric layer 4, and the other outer side (the other end) of the first segment 10b and one outer side of the adjacent middle segment 10c are connected to the first outer fabric layer 1. One outer side of the second segment 10d is connected to the first outer fabric layer 1, and the other outer side of the second segment 10d and one outer side of the adjacent middle segment 10c are connected to the second outer fabric layer 4. The two outer sides of the middle segment 10c are connected to the first outer fabric layer 1 and the second outer fabric layer 4, respectively.

[0079] Specifically, the third outer connection point 12a formed by connecting one outer side of the first segment 10b with the second outer fabric layer 4 maintains a distance from the adjacent second outer connection point 6; the third inner connection point 12c formed by connecting the other outer side of the first segment 10b and one outer side of the adjacent middle segment 10c with the first outer fabric layer 1 maintains a distance from the adjacent first outer connection point 5; the third outer connection point 12b formed by connecting one outer side of the second segment 10d with the first outer fabric layer 1 maintains a distance from the adjacent first outer connection point 5; and the third inner connection point 12d formed by connecting the other outer side of the second segment 10d and one outer side of the adjacent middle segment 10c with the second outer fabric layer 4 maintains a distance from the adjacent second outer connection point 6.

[0080] Along the first extending direction, the plurality of storage channels include adjacent but relatively independent first storage units, a plurality of second storage units, and a third storage unit. The first storage unit includes a first channel 15a, a second channel 15b, a third channel 15c, a fourth channel 15d, and a fifth channel 15e. The first channel 15a and the second channel 15b are arranged along the first extending direction, while the third channel 15e, the fourth channel 15f, and the fifth channel 15g are distributed along the fabric thickness direction and located on the same side of the first channel 15a and the second channel 15b. The second storage unit includes a sixth channel 15e, a seventh channel 15f, an eighth channel 15g, and a fifth channel 15g. Nine channels 15h, six channels 15e, seven channels 15f, eight channels 15g, and nine channels 15h are distributed along the fabric thickness direction and located on the same side of the third channel 15c, the fourth channel 15d, and the fifth channel 15e. Multiple second storage units are distributed sequentially along the first extension direction. The third storage unit includes tenth channel 15i, eleventh channel 15j, twelfth channel 15k, thirteenth channel 15m, and fourteenth channel 15n. Tenth channels 15i, eleventh channels 15j, and twelfth channels 15k are distributed along the fabric thickness direction and located on the same side of the thirteenth channel 15m and the fourteenth channel 15n.

[0081] In this example, compared to Example 1, the number of storage channels is increased. After the filler is filled, the filler can be better contained while ensuring the outer surface of the fabric is flat, preventing the filler from escaping and improving the down-proof properties of the garment. The first and second sections are also designed to better separate the first and second outer fabric layers when the fabric is in use, resulting in smoother surfaces for both layers. Furthermore, the increased number of storage channels further enhances down-proof properties.

[0082] Example 3

[0083] The difference between this example and Example 1 is as follows: See Figure 8 The first inner fabric layer 2 and the second inner fabric layer 3 are arranged sequentially in the thickness direction of the fabric. The inner side of the first inner fabric layer 2 is connected to the inner side of the second inner fabric layer 3. The outer side of the first inner fabric layer 2 is connected to the first outer fabric layer 1 to form multiple first outer connection points 5. The outer side of the second inner fabric layer 3 is connected to the second outer fabric layer 4 to form multiple second outer connection points 6.

[0084] In this example, if the first inner fabric layer 2 first connects to the first outer fabric layer 1 to form the first outer connection point 5, then connects downwards to the second inner fabric layer 3 to form the inner connection point 7, and then connects upwards to the first outer fabric layer 1 to form the first outer connection point 5, and then connects downwards to the second inner fabric layer 3 to form the inner connection point 7, and then connects upwards to the first outer fabric layer 1 to form the first outer connection point 5, and so on, then in use, a similar structure is formed. Figure 8 The diagram shows a broken line shape.

[0085] The second inner fabric layer 3 first connects to the second outer fabric layer 4 to form the second outer connection point 6, then crosses upwards to connect with the second inner fabric layer 3 to form the inner connection point 7, and then connects downwards to connect with the second outer fabric layer 4 to form the second outer connection point 6. This process is repeated, forming a similar configuration when in use. Figure 8 The diagram shows a broken line shape.

[0086] In the preferred embodiment of this example, multiple inner connection points 7, multiple first outer connection points 5, and multiple second outer connection points 6 are each evenly distributed along a first extending direction. The first outer connection points 5 and the corresponding second outer connection points 6 are directly opposite each other in the fabric thickness direction. Only the first outer connection points 5 are provided on the first outer fabric layer 1, and the distance a1 between any two adjacent first outer connection points 5 is equal. Only the first outer connection points 5 are provided on the second outer fabric layer 4, and the distance b1 between any two adjacent second outer connection points 6 is equal, and a1 and b1 are equal. The inner connection points 7 are located at 1 / 2 of the fabric thickness. The first storage channel 8a and the second storage channel 8b are both isosceles triangles. The third storage channel 8c has a square or rectangular cross-section.

[0087] More preferably, both the first storage channel 8a and the second storage channel 8b are isosceles right triangles.

[0088] In other embodiments, the spacing a1 between two adjacent first outer connecting points 5 on the first outer fabric layer 1 is not equal; and the spacing b1 between two adjacent second outer connecting points 6 on the second outer fabric layer 4 is not equal. Different patterns can be presented on the outer surfaces of the first outer fabric layer 1 and the second outer fabric layer 4, resulting in different styles when made into clothing or textiles, offering a variety of forms to meet different needs.

[0089] Example 4

[0090] This example provides a down jacket; see [link / reference] Figure 1-8 The storage channel of the down jacket fabric is filled with filler material, which is the fabric of Example 1, Example 2 or Example 3.

[0091] When the storage channels of a down jacket are filled with filling material, the filling material will not leak out from the joints, resulting in high down-proof properties, a smooth outer surface, and a uniform dyeing effect; it can also display different graphic styles.

[0092] Due to the flexibility of fabrics, when made into clothing such as down jackets, the cross-sectional shape of the fabric's storage channels will change. For example, they will not be regular triangles or quadrilaterals, but rather the sides will be curved.

[0093] In the above embodiments, each segment of the first inner fabric layer 2 is as follows: Figure 9 As indicated in section 2a, each segment can be divided into two parts along the corresponding inner connection point, and these two parts form an inclined plane when the fabric is in use; each segment of the second inner fabric layer 3 is as follows Figure 10 As indicated in section 3a, each segment can be divided into two parts along the corresponding inner connection point, and when the fabric is in use, these two parts form an inclined plane.

[0094] In the above embodiments, the warp, weft, warp density, and weft density of the first outer fabric layer 1, the first inner fabric layer 2, the second inner fabric layer 3, and the second outer fabric layer 4 can be selected from different configuration combinations shown in Table 1 below. When the fabric also includes a third inner fabric layer 10, the warp, weft, warp density, and weft density of the third inner fabric layer 10 are consistent with the warp, weft, warp density, and weft density of the first inner fabric layer 2 or the second inner fabric layer 3.

[0095] When different warp and weft yarns, warp density, and weft density are selected for fabrics, whether it is clothing, textiles, or floating structures, the finished products have a wider variety of forms and functions.

[0097]

[0098]

[0099] As can be seen from the above embodiments, the advantages of the fabric of this utility model include at least the following:

[0100] 1. The first inner fabric layer is connected to at least one of the first outer fabric layer and the second outer fabric layer, and the second inner fabric layer is connected to at least one of the first outer fabric layer and the second outer fabric layer. The connection does not damage the structure of the first outer fabric layer and the second outer fabric layer. When the filling material is filled, the filling material will not escape from the connection, and the connection will not be penetrated by cold wind, resulting in high down-proof properties of the garment. The outer surfaces of the first outer fabric layer and the second outer fabric layer are flat and smooth, which can achieve a uniform dyeing effect. Because the outer surfaces of the first outer fabric layer and the second outer fabric layer are flat and smooth, it is easier to achieve a consistent thickness, density, and hand feel throughout the outer surface of the fabric.

[0101] 2. The first inner fabric layer is connected to at least one of the first outer fabric layer and the second outer fabric layer, and the second inner fabric layer is connected to at least one of the first outer fabric layer and the second outer fabric layer. The middle part of the first inner fabric layer is connected to the middle part of the second inner fabric layer. The multiple storage channels formed on the fabric are stable and can better limit the filling material. The multiple storage channels can better distribute the filling material, making the filling material more evenly distributed and improving the warmth retention of the fabric.

[0102] The above embodiments are only for illustrating the technical concept and features of this utility model, and are intended to enable those skilled in the art to understand the content of this utility model and implement it accordingly. They should not be construed as limiting the scope of protection of this utility model. All equivalent changes or modifications made in accordance with the spirit and essence of this utility model should be included within the scope of protection of this utility model.
