Description

Technical Field

[0001] This invention relates to the field of jeans waistbands, and in particular to a double-layer wraparound jeans waistband. Background Technology

[0002] Currently, most traditional trousers or shaping bottoms on the market use a standard straight waistband or a single-layer waistband structure. Their waistline is relatively straight and doesn't conform to the natural curves of the human waist. During wear, uneven fit is common between the waistband and the waist, sides, and lower back, especially at the top and bottom of the waist, where there are often areas of looseness, outward protrusion, or uneven pressure, resulting in insufficient comfort and support.

[0003] Meanwhile, traditional waistband structures often don't fully utilize elasticity. Even if the fabric itself has some stretch, the simple design and stitching of the waistband mean that the fabric's elasticity cannot be fully released and utilized along the curves of the human waist. This results in poor adaptability to people with different body types and waist circumferences. For people with excess fat around the waist or significant changes in waist circumference, traditional waistbands are prone to leaving marks, feeling tight, or becoming loose in certain areas, making it difficult to achieve good coverage, support, and waist protection.

[0004] Furthermore, existing wide-waisted trousers are prone to curling, wrinkling, gaping, or deformation after prolonged sitting, bending, or wearing for extended periods. This is due to the stretching and compression of the waist and abdomen caused by body movements. This not only affects wearing comfort but also reduces the overall smoothness and aesthetics. Particularly in the lower back and side waist areas, the ordinary waistband structure lacks three-dimensional support, making it difficult to stably conform to the body's waistline, often resulting in problems such as an excessively large waistband opening and noticeable gaps at the lower back.

[0005] Furthermore, traditional waistband front structure often uses overlapping and buttoning of left and right waist pieces or multiple layers of fabric for connection. Due to the large number of structural layers, the front center area is prone to problems such as localized heaviness, bulges, or unevenness. Especially in the areas of the front waistband flaps, front center overlaps, and buttons, the multiple layers of fabric, waistband lining, seam allowances, and accessories affect the flatness and refinement of the front waist area, making the front center area appear bulky when worn, and reducing the overall visual slimness and sophistication of the garment.

[0006] Therefore, the existing waist structure still has problems such as poor fit to the human waist, insufficient elasticity, easy rolling up and gaps in the wide waist area, weak three-dimensional support of the waist, and heavy and unsightly front and middle layers. There is an urgent need for a waist structure that can conform to the curvature of the human waist, give full play to the elasticity of the fabric, enhance the waist hugging and fit, reduce the thickness of the front and middle layers, and improve the smoothness of the appearance. Summary of the Invention

[0039] The present invention also provides a sewing method for sewing a waist panel as described in the first aspect of the present invention, the sewing method comprising:

[0040] Fold the bottom fabric of the first main panel to its reverse side to form a first folded panel, and fold the top fabric of the second main panel to its reverse side to form a second folded panel. Sew the first folded panel and the second folded panel together at the folds to connect the first main panel and the second main panel.

[0041] Fold the fabric at both ends of the main panel to its reverse side to form the main folded panel, and fold the fabric at one end of the end panel to its reverse side to form the end folded panel. Sew the main folded panel and the end folded panel together at their folds to connect the main panel and the end panel.

[0042] A substrate is sewn onto the reverse side of the waist panel, so that the main folded piece and the end folded piece are flattened in different directions, while the first folded piece and the second folded piece are flattened in the same direction; for example: the main folded piece faces the main panel, the end folded piece faces the end panel, and the first folded piece and the second folded piece face the first main panel.

[0043] The double-layer wraparound denim waistband provided by this invention has the following beneficial effects:

[0044] 1) The double-layer wraparound waistband of the jeans provided by this invention can fit the human waist. The waistband adopts a double-layer wraparound design (double-layer wraparound means that the main panel is made up of a first main panel and a second main panel, and the first folded piece and the second folded piece are folded together to form a waist-cinching piece), which can better highlight the three-dimensionality of the waist and the waist-cinching function, as well as bring a slim and beautiful appearance to the waist. At the same time, the open seam splicing process is made under the front waistband, and the front center does not have a double-layer waistband design, which can perfectly avoid the thickness of the front center overlap (that is, the waist-cinching piece does not extend to the end panel, and the thickness of the placket formed by the two end panels after overlapping is relatively thin), which reflects the smoothness and refinement of the front center.

[0045] 2) Furthermore, the waist trainer can have a waist-cinching effect. For people with thicker or thinner waists, the waist trainer has a certain shaping effect, preventing the main body piece from collapsing inward and bulging outward, and maintaining the flatness of the waist.

[0046] 3) Furthermore, the double-layer wrap-around waistband of the jeans used in this invention has an arc that can better reflect the elasticity of the fabric, thus demonstrating the strong inclusiveness of the curved waist. Attached Figure Description

[0072] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention. In the description of the present invention, it should be noted that the terms "top edge," "bottom edge," "end," "both ends," "one end," "side edge," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the present invention. In addition, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0073] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the term "connection" should be interpreted broadly, for example, it can refer to a fixed connection, a detachable connection, or an integral connection. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances. The "connection" between fabrics mentioned herein can refer to sewing, that is, using needle and thread to sew the common edges of the fabrics together to join two pieces of fabric.

[0074] Before providing a detailed explanation of the invention, let's first clarify the concept of a jeans waistband: A jeans waistband is typically made by stacking and sewing two layers of fabric together. The layer that comes into contact with the body is called the lining (2) or simply the waist lining, while the layer that doesn't come into contact with the body is called the outer waistband (1) or simply the outer waistband. The reverse side of the outer waistband (1) and the reverse side of the lining (2) are the opposite sides of the outer waistband (1) and the inner waistband (2). The front side of the outer waistband (1) and the front side of the lining (2) are the opposite sides of their respective reverse sides. The concepts of reverse and front also extend to the sub-concepts of the outer waistband (1) and the lining (2). For example, the reverse side of the main outer waistband (1-1) should be the same as the reverse side of the outer waistband (1). Similarly, the front side of the end face (1-2) should be the same as the front side of the outer waistband (1). In addition, the waistband of jeans usually consists of a front waistband and a back waistband. The waistband of jeans is cut into two parts from the coronal plane of the human body. The part that contacts the abdomen is the front waistband, and the part that contacts the back waistband is the back waistband.

[0075] The first aspect of this invention provides a waistband panel suitable for jeans, as shown in FIG1. ​​The waistband panel 1 includes a main panel 1-1 and two end panels 1-2, which are located at both ends of the main panel 1-1 and connected to it respectively. The main panel 1-1 includes a first main panel 1-1-2 and a second main panel 1-1-3 connected thereto. The bottom fabric of the first main panel 1-1-2 is folded to its reverse side, and the top fabric of the second main panel 1-1-3 is folded to its reverse side. The folded fabrics overlap to form a waistband 3. Specifically, the first main panel 1-1-2 and the second main panel 1-1-3 are sewn together at the folds of the first and second folded panels.

[0076] Among them, the waist-cinching piece 3 can have a waist-cinching effect. For people with thicker or thinner waists, the waist-cinching piece 3 has a certain shaping effect, preventing the main piece 1-1 from collapsing inward and bulging outward, and maintaining the flatness of the waist.

[0077] A second aspect of the present invention provides a double-layer wraparound jeans waistband, as shown in FIG4, comprising a waistband lining 2 and a waistband facing 1 provided in the first aspect of the present invention, wherein the waistband facing 1 overlaps with and is connected to the waistband lining 2. As shown in FIG5, the jeans waistband also includes an ear flap 4, wherein a seam 5 is formed at the connection between the main facing 1-1 and the end facing 1-2, the ear flap 4 is connected to the waistband facing 1, and the seam 5 located on the front of the waistband facing 1 is covered by an ear flap 6 located at the front waistband.

[0078] It is important to emphasize that the waistband 3 does not extend throughout the entire waistband, but only within the area of ​​the main panel 1-1. The fly of the jeans is formed by the partial overlap of the end panels 1-2. This maintains the aforementioned benefits while reducing the thickness of the waistband in the fly area, thus increasing comfort. Simultaneously, the seam 5 formed between the main panel 1-1 and the end panels 1-2 is concealed by the flaps 4, maintaining the aesthetic appeal of the waistband.

[0079] Further, as shown in Figures 1 and 2, a substrate 6 is provided on the reverse side of the waist panel 1, and substrates 6 are provided at both ends of the reverse side of the waist panel 2. Specifically, the substrate 6 can be a PCC liner, which is a commercially available liner. The PCC liner has a warp elasticity of 30.62%, a weft elasticity of 33.07%, an adhesion speed of 14 seconds, a temperature of 150°C, and a pressure of 3 kg. Other liners with the same or similar effects as the PCC liner should also be within the scope of protection of this invention. For example, a certain liner has a warp elasticity of 25-35%, a weft elasticity of 25-35%, an adhesion speed of 10-20 seconds, a temperature of 120-180°C, and a pressure of 2-4 kg.

[0080] Further, as shown in Figure 1, the fabric at both ends of the main panel 1-1 is folded towards its reverse side to form a main folded panel 1-1-1, and the fabric at the end of the end panel 1-2 near the main panel 1-1 is folded towards its reverse side to form an end folded panel 1-2-1. The seam 5 is located between the main folded panel 1-1-1 and the end folded panel 1-2-1. The main panel 1-1 and the end panel 1-2 are sewn together at the folds of the main folded panel 1-1-1 and the end folded panel 1-2-1. Even further, as shown in Figure 1, the main folded panel 1-1-1 overlaps with the main panel 1-1, and the end folded panel 1-2-1 overlaps with the end panel 1-2.

[0081] Further, as shown in Figure 2, the top and bottom fabrics of the waist lining 2 are folded toward their reverse side to form the upper waist lining fabric 2-1 and the lower waist lining fabric 2-2, respectively, forming a second gap between the upper waist lining fabric 2-1 and the lower waist lining fabric 2-2. As shown in Figure 3, the top and bottom fabrics of the waist panel 1 are folded to their reverse side to form the upper waist panel fabric 1-3 and the lower waist panel fabric 1-4, respectively, and a first gap is formed between the upper waist panel fabric 1-3 and the lower waist panel fabric 1-4. Specifically, the lining piece 2 and the outer piece 1 are sewn together at the folds of the upper fabric 2-1 and the upper fabric 1-3 of the lining piece, and at the folds of the lower fabric 2-2 and the lower fabric 1-4 of the outer piece.

[0082] Furthermore, the edges of the lower fabric 1-4 of the waist panel and the lower fabric 2-2 of the waist lining are staggered to form a full-edge design as described in Embodiment 1.

[0084] In one feasible embodiment, the width of the end fold is 0.8~1.2 cm.

[0085] In one feasible embodiment, the width of the first folded piece is 0.8 to 1.2 cm.

[0086] In one feasible embodiment, the width of the second folded piece is 0.8 to 1.2 cm.

[0087] In one feasible embodiment, the width of the waistband is 0.8~1.2 cm.

[0088] In one feasible embodiment, the first gap With the second gap The width difference is 2.5~6.5 cm.

[0089] In one feasible embodiment, such as Figure 8 As shown, the first gap The width is 0~1 cm;

[0090] In one feasible embodiment, such as Figure 8 As shown, the second gap The width is 2.5~6.5 cm.

[0091] In one feasible embodiment, such as Figure 7 As shown, the height of the waist panel 1 It ranges from 4 to 8.5 cm.

[0092] In one feasible embodiment, such as Figure 6 As shown, the height of the waist panel 2 It ranges from 4 to 8.5 cm.

[0093] In one feasible embodiment, the height of the first main panel 1-1-2 is 2.3~4.55 cm.

[0094] In one feasible embodiment, the height of the second main panel 1-1-3 is 1.7~3.95 cm.

[0095] In one feasible embodiment, such as Figure 7 As shown, the arch height of the upper edge of the waist panel 1 It ranges from 3 to 11 cm.

[0096] In one feasible embodiment, such as Figure 6 As shown, the arch height of the upper edge of the waist panel 2 It ranges from 3 to 11 cm.

[0097] In one feasible embodiment, such as Figure 7 As shown, the width of the upper fabric 1-3 of the waist panel is 0.8~1 cm, and the width of the lower fabric 1-4 of the waist panel is 3~8 cm.

[0098] In one feasible embodiment, such as Figure 6 As shown, the width of the upper fabric 2-1 of the waist lining is 0.8~1 cm, and the width of the lower fabric 2-2 of the waist lining is 0.8~1 cm.

[0099] In one feasible embodiment, as shown in FIG1, the width of the main folded piece 1-1-1 is 0.8~1.2 cm.

[0100] In one feasible embodiment, as shown in FIG1, the width of the end folding piece 1-2-1 is 0.8~1.2 cm.

[0101] The present invention also provides a sewing method for sewing a waist panel as provided in the first aspect of the present invention, the sewing method comprising the following steps:

[0102] Step 1) Fold the bottom fabric of the first main panel 1-1-2 to its reverse side to form a first folded panel, and fold the top fabric of the second main panel 1-1-3 to its reverse side to form a second folded panel. Sew the folds of the first and second folded panels together to connect the first main panel 1-1-2 and the second main panel 1-1-3.

[0103] Step 2) Fold the fabric at both ends of the main face piece 1-1 to its reverse side to form the main folded piece 1-1-1, and fold the fabric at one end of the end face piece 1-2 to its reverse side to form the end folded piece 1-2-1. Sew the fabric at the folds of the main folded piece 1-1-1 and the end folded piece 1-2-1 to connect the main face piece 1-1 and the end face piece 1-2.

[0104] Step 3) Sew the substrate 6 on the reverse side of the waist panel 1, so that the main folded piece 1-1-1 and the end folded piece 1-2-1 are flattened in different directions, and the first folded piece and the second folded piece are flattened in the same direction; for example: the main folded piece 1-1-1 faces the main panel 1-1, the end folded piece 1-2-1 faces the end panel 1-2; the first folded piece and the second folded piece face the first main panel 1-1-2.

[0105] Example 1

[0106] In this embodiment, a full hem below the waist is used for medium-thin and light-colored fabrics (6~12.5 oz / yd²). The full hem below the waist is, for example... Figure 8 As shown, a full stop means that the width of the lower fabric 1-4 of the waist panel is greater than the width of the upper fabric 1-3 of the waist panel, and there is almost no first gap between the lower fabric 1-4 and the upper fabric 1-3 of the waist panel. However, a noticeable second gap still forms between the upper fabric 2-1 and the lower fabric 2-2 of the waist lining. Second gap It can effectively reduce the thickness of the entire waistband of jeans.

[0107] Meanwhile, a backing 6 is provided on the reverse side of the waistband panel 1, and a backing 6 is provided at both ends of the reverse side of the waistband lining panel 2. The backing 6 is made of PCC lining, with a warp elasticity of 30.62%, a weft elasticity of 33.07%, an bonding speed of 14 seconds, a temperature of 150℃, and a pressure of 3kg. The backing 6 prevents the formation of washing channels in medium-thin fabrics and light-colored denim jeans during washing, and prevents the waistband from curling or becoming loose, keeping the waistband flat.
