AI Technical Summary
The armholes of lightweight and soft fabrics are prone to permanent wrinkles due to arm movements. In existing technology, the seams are exposed on the fabric surface, and the lack of a cushioning structure leads to stress concentration, resulting in wrinkling problems.
A wrinkle-resistant fabric strip is added at the armhole seam connection to form a ring-shaped reinforcement layer. The strip is sewn along the armhole track to the outside of the garment body and sleeves, and connected by blind stitches to form a ring structure that completely covers the seam connection. The wrinkle-resistant fabric's resistance to deformation disperses stress and hides the seam on the inside of the fabric.
It effectively reduces wrinkles at the armhole, enhances the rigidity and aesthetics of the connecting parts, ensures that the seams are hidden, and improves the wearing experience.

Abstract
Description
Technical Field
[0001] This utility model relates to the field of clothing technology, and in particular to a wrinkle-resistant structure for clothing armholes. Background Technology
[0002] In garment structural design, the armhole (the connection between the bodice and sleeve) is one of the areas with the highest frequency of movement and the most complex stress on the fabric. This is especially true for lightweight and soft fabrics like silk and chiffon, which are prone to wrinkling due to the following issues: Traditional armholes use a "direct splicing + topstitching" technique: the fabric edges of the bodice and sleeve are directly aligned and connected via a straight seam or overlock seam, with the seams exposed on the fabric surface. This structure has the following drawback: when the arm moves, the fabric at the armhole forms a "stretch-contraction" cycle along the shoulder and armpit. Because there is no cushioning structure at the seam connection, the fabric is prone to permanent wrinkles at stress concentration points (such as the armpit joint and shoulder end).
[0003] To solve the problem of armhole wrinkling, especially for lightweight and soft fabrics, a wrinkle-resistant structure for garment armholes is needed. Utility Model Content
[0004] This utility model provides a wrinkle-resistant structure for garment armholes to solve the problems in the prior art.
[0005] The present invention adopts the following technical solution: a wrinkle-resistant structure for garment armholes, comprising a garment body and two sleeves, wherein the garment body has two symmetrical armholes and the two sleeves are respectively installed at the two armholes; the wrinkle-resistant structure further comprises: two strips of fabric, both made of wrinkle-resistant fabric, wherein both ends of the strips are folded inward along their length to form inner layers, and the fold lines of the two inner layers are distributed in parallel; the two strips of fabric are respectively located outside the two armholes, and each strip of fabric is sewn along the corresponding armhole trajectory at the seam connection between the sleeve and the garment body, so that the two fold lines of the strip of fabric are connected by a blind stitch to form a loop structure and completely cover the seam connection.
[0006] Preferably, the portion of the inner layer that protrudes from the side of the fabric strip in the width direction is defined as a protrusion, which is removed by cutting.
[0007] Preferably, the inner layer is sewn onto the strip of fabric along its outer contour and through a first seam.
[0008] Preferably, the fabric strip has its two sides folded inward along its width and sewn onto the garment body and sleeves via concealed stitching.
[0009] Preferably, the two fold lines of the fabric strip are located at the underarm joint of the sleeve.
[0010] Preferably, the fabric strip is configured as a twill fabric.
[0011] The above-mentioned technical solutions adopted in the embodiments of this utility model can achieve the following beneficial effects:
[0012] This anti-wrinkle structure creates a ring-shaped reinforcement layer by adding a strip of anti-wrinkle fabric at the armhole seam connection. The strip is sewn along the armhole track to the outside of the seam between the garment body and the sleeve, completely covering the seam connection. Utilizing the anti-wrinkle fabric's resistance to deformation, it restrains the relative displacement of the garment body and sleeve during movement, dispersing tensile stress in the shoulder and armpit areas, thereby reducing fabric wrinkles. The two ends of the strip are folded inward to form parallel fold lines, which are then connected into a loop structure through blind stitching (such as concealed stitching or picked-up stitching). This avoids the thickness buildup of traditional "layered connections," resulting in smooth edges, uniform thickness at the connection, and the seams hidden inside the fabric.

[0024] 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.
[0025] The technical solutions provided by the various embodiments of this utility model are described in detail below with reference to the accompanying drawings.
[0026] The existing garments are prone to wrinkling at the junction of the bodice 1 and sleeve 2, especially for garments made of silk, where the wrinkling is more severe. Therefore, referring to... Figures 1 to 8 As shown, this utility model embodiment provides a wrinkle-resistant structure for garment armholes, including a garment body 1 and two sleeves 2. The garment body 1 has two symmetrical armholes, and the two sleeves 2 are respectively installed at the two armholes. The wrinkle-resistant structure also includes: two fabric strips 3, both made of wrinkle-resistant fabric. The two ends of the fabric strips 3 are folded inward along their length to form inner layers 31, and the fold lines 32 of the two inner layers 31 are distributed in parallel. The two fabric strips 3 are located on the outside of the two armholes, and each fabric strip 3 is sewn along the corresponding armhole trajectory at the seam connection between the sleeve 2 and the garment body 1, so that the two fold lines 32 of the fabric strip 3 are connected by a blind stitch to form a loop structure and completely cover the seam connection.
[0027] In this embodiment, the anti-wrinkle structure forms a ring-shaped reinforcing layer by adding an anti-wrinkle fabric strip 3 at the armhole seam connection. The strip 3 is sewn along the armhole track to the outside of the seam between the garment body 1 and the sleeve 2, completely covering the seam connection. Utilizing the anti-deformation ability of the anti-wrinkle fabric, it restrains the relative displacement of the garment body 1 and the sleeve 2 during movement, dispersing the tensile stress in the shoulder and armpit areas, thereby reducing fabric wrinkles. The two ends of the strip 3 are folded inward to form parallel fold lines 32, which are connected into a ring structure by blind stitching (such as concealed stitching or pick stitching). This avoids the thickness accumulation of traditional "layered connection," making the edge of the connection smooth and the thickness uniform, and the seam hidden inside the fabric.
[0028] Using a wrinkle-resistant fabric (such as twill) as the main material for strip 3 can suppress wrinkles caused by repeated friction and stretching of the fabric at the armhole. The ring structure formed by strip 3 wraps around the armhole seam, enhancing the overall rigidity of the connection between the garment body 1 and the sleeve 2, and preventing structural collapse or wrinkling of the silk fabric due to its softness. Specifically, strip 3 forms a closed loop by connecting its two ends, which can cover the armhole seam 360° without dead angles, ensuring that areas prone to wrinkling, such as the shoulder, armpit, and sleeve cap, are evenly supported. It is especially effective in suppressing wrinkles caused by the multi-directional stretching of silk fabric during movements such as raising the arm and bending over.
[0029] In addition, since the armhole itself is a three-dimensional curved surface (the front armhole is rounded, and the back armhole is slightly steeper), the fabric strip 3 needs to be sewn along the curve. If a vertical fold is used (the fold line 32 is perpendicular to the length of the fabric strip 3), when the two ends of the fabric strip 3 are connected, excess fabric will accumulate due to the angle difference between the straight edge and the curved trajectory, resulting in local bulges or wrinkles; while a tilted fold can adjust the fold angle (usually at an angle of 15°-30° with the tangent of the armhole curve) so that the two ends of the fabric strip 3 naturally narrow, matching the curvature of the armhole, and the circular structure after connection fits the human shoulder contour better; the fabric strip 3 surrounds the outside of the sleeve and the body, so even if there are wrinkles at the armhole, they will be covered by the fabric strip 3 to prevent wrinkles from being exposed.
[0030] It should be noted that the portion of the inner layer 31 that protrudes from the side of the fabric strip 3 in the width direction is defined as the protrusion 33, which is removed by cutting. After removing the protrusion 33, the width of the fabric strip 3 is uniform (without local widening), improving the aesthetics of the fabric strip 3.
[0031] Specifically, the inner layer 31 is sewn onto the fabric strip 3 along its outer contour and through the first seam 4. The first seam 4 is sewn along the edge of the inner layer 31 to improve its stability.
[0032] In some practical applications, refer to Figure 1 , Figures 6 to 7 As shown, the fabric strip 3 has two sides folded inward along its width direction and is sewn onto the garment body 1 and sleeve 2 via concealed seams 5 (e.g., Figure 6 (This is a schematic diagram of the sewing position of the concealed seam 5). The two sides of the fabric strip 3 are folded inwards along its width (forming a narrow inner fold layer, this inner fold layer is the...) Figure 7 The lower folds at both ends of the central fabric strip are simultaneously fixed to the fabric of the bodice 1 and sleeve 2 via concealed stitching 5 (such as concealed hemming or facing stitching), further enhancing the structural stability and wrinkle resistance of the armhole connection area. The inner folded edge is fixed by concealed stitching 5, with the stitching completely hidden in the fabric interlayer, solving the problem of snagging on the side edges of silk fabric; at the same time, the inner folded edge makes the joint between the fabric strip 3 and the bodice 1 / sleeve 2 smooth, with no protrusion felt when touched from the inside of the garment, thus providing a better wearing experience.
[0033] In some practical applications, the two fold lines 32 of the fabric strip 3 are located at the underarm joint of the sleeve 2 (e.g. Figure 1 This is only a front view of the garment; the positions of the two fold lines are not shown in detail. Since the two fold lines 32 of the fabric strip 3 are sewn together using a blind stitch technique, there will still be a noticeable seam at the seam. However, placing the seam at the armpit joint effectively hides the seam and improves the garment's aesthetics.
