Description

Technical Field

[0001] This utility model relates to the field of garment dart structure technology, and in particular to a fabric dart structure. Background Technology

[0002] In the field of garment manufacturing, darts are a key technique for shaping garments into a three-dimensional form and conforming to the curves of the human body. By folding and sewing the excess fabric to form darts, a garment can achieve a fitted effect in areas such as the chest, waist, and hips. Its structural design directly affects the smoothness, crispness, and lifespan of the garment.

[0003] Traditional dart construction typically employs a single-sided folding and sewing method, where the dart is folded only to one side of the fabric and then directly secured. This structure results in a significant difference in fabric thickness on both sides of the dart seam—the folded side is thicker due to the multiple layers of fabric, while the other side is thinner due to the single layer of fabric, creating an asymmetrical "one side thick, one side thin" situation. This uneven thickness can easily cause bulges, dents, or misalignments on the garment surface, severely affecting the garment's smoothness and aesthetics. Utility Model Content

[0004] This utility model provides a fabric gathering structure to solve the problems in the prior art.

[0005] The present invention adopts the following technical solution: a fabric dart structure, including a dart pleat formed by the inward dart of the fabric and a dart seam located on the outer side of the fabric. The dart pleat has a double-layer structure. A first seam is sewn along the direction of the dart seam to sew the opening of the dart pleat at the dart seam. The dart pleat is folded to the right along the first seam and attached to the inner side of the fabric. A rectangular fabric piece is also provided on the inner side of the fabric. The rectangular fabric piece is folded to form a double-layer structure. One side of the rectangular fabric piece is aligned with the first seam and fixed to the dart pleat. The length of one side of the rectangular fabric piece is the same as that of the dart seam. The rectangular fabric piece is folded to the left along the first seam and attached to the inner side of the fabric.

[0006] Preferably, the rectangular fabric piece and the pleats are both ironed flat and shaped.

[0007] Preferably, the rectangular fabric piece is folded to form a central fold line, which is aligned with the first seam. The rectangular fabric piece is then sewn onto the dart at the first seam from the inside of the central fold line via a second seam.

[0008] Preferably, both the fabric and the rectangular fabric piece are twill fabric.

[0009] Preferably, a cover strip is connected to the outside of the dart and rectangular fabric piece, which completely covers the dart and rectangular fabric piece.

[0010] Preferably, the fabric strip is configured as an adhesive backing and is bonded to the fabric by high-temperature pressing.

[0011] The above-mentioned technical solutions adopted in the embodiments of this utility model can achieve the following beneficial effects:

[0012] Firstly, traditional dart structures suffer from uneven thickness due to the single-sided stacking of darts, which can easily lead to bulges and misalignment. In contrast, this structure uses a symmetrical double-layer folding design, with a double-layer dart structure on one side and a double-layer rectangular fabric structure on the other side, ensuring that the thickness on both sides of the dart seam is completely consistent, with no bulges or depressions on the fabric surface, thus greatly improving the smoothness of the garment.

[0013] Secondly, with equal thickness on both sides of the dart, the fabric is stressed more evenly, which can prevent the dart from shifting and the fabric from wrinkling due to excessive tension on one side, thus extending the garment's crispness and lifespan.

[0014] Thirdly, compared to the existing cutting and sewing method, which requires directly cutting the fabric at the dart pleat, then sewing it to both sides, and then finishing the cut with overlocking and other steps, which damages the original integrity of the fabric, especially for thin or easily frayed fabrics, potentially leading to edge wear, fraying, and increased post-processing difficulty, the present application uses a rectangular fabric piece that is the same length as the dart pleat and is fixed with one side aligned with the first seam. This eliminates the need for complex positioning or cutting, facilitates mass production, and does not damage the original integrity of the fabric. Attached Figure Description

[0023] To further illustrate the technical means and effects adopted by this utility model in order to achieve the intended utility model purpose, the following detailed description of the specific implementation methods, structure, features and effects of this utility model is provided in conjunction with the accompanying drawings and preferred embodiments.

[0024] The technical solutions provided by the various embodiments of this utility model are described in detail below with reference to the accompanying drawings.

[0025] Reference Figures 1 to 4 As shown, this utility model embodiment provides a fabric dart structure, including dart pleats 11 formed by the inward dart of fabric 1 (as shown in the figure). Figure 4 The fabric 1 includes a dart 12 located on the outer side of the fabric 1. The dart 11 has a double-layer structure. A first seam is sewn along the direction of the dart 12 to sew the opening of the dart 11 at the dart 12. The dart 11 is folded to the right along the first seam and adhered to the inner side of the fabric 1. A rectangular fabric piece 2 is also provided on the inner side of the fabric 1. The rectangular fabric piece 2 is folded to form a double-layer structure. One side of the rectangular fabric piece 2 is aligned with the first seam and fixed to the dart 11, and the length of one side of the rectangular fabric piece 2 is the same as that of the dart 12. The rectangular fabric piece 2 is folded to the left along the first seam and adhered to the inner side of the fabric 1 (e.g., ...). Figure 2 It should be noted that folding the rectangular fabric piece to the left and folding the darts to the right are relative terms; it is also possible for the rectangular fabric piece to be folded to the right while the darts are folded to the left.

[0026] The dart 11 has a double-layer structure. After being folded to the right along the first seam, it is attached to the inside of the fabric 1. At this time, one side of the dart 11 forms a three-layer structure of "fabric 1 + double-layer dart 11" (one layer of fabric 1 + two layers of dart 11). The rectangular fabric piece 2 is folded into a double-layer structure. One side of it is aligned with the first seam and fixed to the dart 11 (to ensure accurate positioning). Then, it is folded to the left along the first seam and attached to the inside of the fabric 1. At this time, one side of the rectangular fabric piece 2 forms a three-layer structure of "fabric 1 + double-layer rectangular fabric piece 2" (one layer of fabric 1 + two layers of rectangular fabric piece 2).

[0027] In traditional dart structures, after folding the dart 11 on one side, only one side has a double layer (the total thickness is one layer of fabric 1 + two layers of dart 11 = 3 layers). Therefore, this fabric dart structure balances the thickness on both sides of the dart seam 12 by using a double-layered folding structure of rectangular fabric pieces 2 symmetrically arranged with the two layers of dart 11, thus solving the problem of "unilateral thickening" in traditional dart structures. Furthermore, the first seam not only sewn the opening of the dart 11 but also serves as a "shared baseline" for the dart 11 and the rectangular fabric piece 2, ensuring that the two are folded in opposite directions but symmetrically distributed, avoiding thickness differences caused by positional offsets. At the same time, the fixation of the rectangular fabric piece 2 and the dart 11 enhances the stability of the overall structure. It should be noted that both the rectangular fabric piece 2 and the dart 11 are ironed flat to ensure their flatness.

[0028] In summary, traditional dart structures, due to the single-sided stacking of dart pleats 11, result in "one side being thick and the other side being thin," which easily leads to problems such as bulging and skewing. However, this structure, through a symmetrical double-layer folding design, namely a double-layer dart pleat 11 structure on one side and a double-layer rectangular fabric piece 2 structure on the other side, ensures that the thickness of both sides of the dart seam 12 is completely consistent (both are 3 layers), and the surface of the fabric 1 has no bulges or depressions, greatly improving the smoothness of the garment.

[0029] In addition, with equal thickness on both sides of the dart 12, the fabric 1 is subjected to more even stress, which can prevent the dart 12 from shifting and the fabric 1 from wrinkling due to excessive tension on one side (such as the waist dart 12 being pulled to one side due to tension difference when wearing the garment), thus extending the garment's crispness and lifespan.

[0030] In contrast to existing cutting and sewing methods that require directly cutting the fabric 1 at the dart 11, then sewing it to both sides, and finally finishing the cut with overlocking, which damages the original integrity of the fabric 1, especially for thin, easily frayed fabrics (such as silk and chiffon), potentially leading to edge wear, fraying, and increased post-processing difficulty, the present application uses a rectangular fabric piece 2 that is the same length as the dart 11 and is fixed with one side aligned with the first seam. This eliminates the need for complex positioning or cutting, facilitating mass production and preserving the integrity of the original fabric 1.

[0031] In some practical applications, the rectangular fabric piece 2 is folded to form a central fold line, which is aligned with the first seam. The rectangular fabric piece 2 is then sewn onto the dart 11 at the first seam from the inside of the central fold line via a second seam. It should be noted that the accompanying drawings of this application are for illustrative purposes only, showing the first and second seams.

[0032] If the rectangular fabric piece 2 is aligned by feel alone, it is easy for it to shift to the left or right (e.g., shifting to the left by 1mm, resulting in the left side being slightly thicker and the right side slightly thinner). However, in this embodiment, the center fold line formed by folding the rectangular fabric piece 2 is its own folding baseline. Aligning this center fold line with the first seam (i.e., the baseline of the dart 12) can prevent the rectangular fabric piece 2 from shifting to the left or right, thereby ensuring that the thickness on both sides is balanced.

[0033] The second seam is sewn from the inside of the center fold line of the rectangular fabric piece 2 (i.e., inside the folded double-layer structure) to the dart 11 at the first seam. This fixing method does not penetrate the outside of the fabric 1, but only completes the connection between the dart 11 and the rectangular fabric piece 2. This avoids the seam being exposed and damaging the appearance. At the same time, the second seam further strengthens the structural strength of the dart 12, which can prevent the seam from breaking due to stretching during the wearing of the garment. In practical applications, both the fabric 1 and the rectangular fabric piece 2 are twill fabrics. Twill fabrics have better stretchability along the diagonal weave (especially in the 45° direction). When the dart 11 (double-layer twill fabric) is folded to the right along the first seam and the rectangular fabric piece 2 (double-layer twill fabric) is folded to the left along the center fold line, the stretchability of the twill allows the fabric to more easily adapt to the folding angle.

[0034] In other practical applications, a cover strip 3 (such as...) is connected to the outside of the pleat 11 and the rectangular fabric piece 2. Figure 1 and Figure 2 The cover strip 3 completely covers the pleat 11 and the rectangular fabric 1. Specifically, the cover strip 3 is configured as an fusible interfacing and is bonded to the fabric 1 by high-temperature pressing.

[0035] The fusible interfacing (fabric strip 3) completely covers the outer sides of the dart 11 and the rectangular fabric piece 2. High-temperature pressing melts the adhesive layer on the back of the fusible interfacing, bonding it to the inner side of the fabric 1 (dart 11, rectangular fabric piece 2, and base fabric 1) to form a single unit. At this point, the fusible interfacing not only physically covers the overlapping area of ​​the dart 11 (right-folded double layer) and the rectangular fabric piece 2 (left-folded double layer), but also firmly secures the three components (dart 11, rectangular fabric piece 2, and base fabric 1) through adhesiveness.

[0036] In addition, the fusible interfacing itself has a certain rigidity (divided into soft, medium and hard types according to thickness), and will be shaped according to the fabric 1 after high temperature pressing. Since the dart 11 and the rectangular fabric piece 2 have formed a structure with equal thickness on both sides (both 3 layers) through symmetrical folding, the fusible interfacing will lock this flat shape when covering, avoiding unilateral thickening or bulging caused by the natural rebound of the fabric 1.

[0037] Furthermore, the fusible interlining is fixed by high-temperature heat pressing without needles and threads, completely covering the edges of the darts 11 and the rectangular fabric piece 2, the first seam, the second seam, and any overlapping marks. No stitches are visible on the outside of fabric 1, enhancing the garment's luxurious feel (especially for haute couture suits). Simultaneously, the double-layered folded structure of the darts 11 and the rectangular fabric piece 2 is prone to edge wear and pilling due to friction during daily wear (such as contact with underwear or other fabrics 1). The fusible interlining, acting as a protective layer, isolates the internal structure from external friction, reducing the risk of fraying and damage.

Although the present utility model has been disclosed above with reference to a preferred embodiment, it is not intended to limit the present utility model. Any person skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present utility model.
