Abstract
Description
Technical Field
[0001] This utility model relates to the field of clothing technology, and more specifically to a top with a belly-covering structure. Background Technology
[0002] Traditional tops, such as the polo shirt, are a classic garment that falls between a formal shirt and a casual T-shirt. Known for its comfort, versatility, and business casual style, it's widely used in the workplace, sports, and everyday wear. Polo shirts typically have a straight or inverted trapezoidal silhouette (narrower at the top and wider at the bottom). A straight-cut polo shirt can appear slightly loose, making the wearer look bulky. To balance functionality, traditional aesthetics, and ergonomics, most polo shirts today are inverted trapezoidal in shape. Figure 1 As shown, the chest circumference is 1-2cm larger than the hem circumference, and the waist and abdomen of the polo shirt are narrowed, causing the polo shirt to cling to the abdomen and highlight the wearer's body shape defects.
[0003] In addition, polo shirts are generally made with a loose cut or elastic fabric, which can easily make them look bulky when worn and prone to deformation after prolonged wear. Furthermore, the front and back panels of a polo shirt are sewn together with parallel seams of equal length, meaning that the seam is parallel to the side of the front or back panel and the seam allowance (the distance from the side of the front or back panel to the seam) is exactly the same. This prevents the polo shirt from creating a three-dimensional effect, making it impossible to conceal the abdomen or create a slimming effect, especially for wearers with a protruding abdomen.
[0004] In view of this, this application has conducted in-depth research on this basis, resulting in this case. Utility Model Content
[0005] The purpose of this invention is to provide a top with a belly-covering structure to provide an invisible concealment for the problem of a protruding abdomen.
[0006] To achieve the above objectives, the solution of this utility model is: a top with an abdominal covering structure, comprising an A-shaped top body, the top body comprising a front piece and a back piece sewn together, the length of the front piece corresponding to the bust line and hemline being greater than the length of the back piece corresponding to the bust line and hemline, and the two side seams of the front piece corresponding to the waistline and abdomen line respectively extending in a direction away from the middle position of the front piece to form protrusions, the side seams of the front piece on the same side corresponding to the bust line and the protrusions and the protrusions and the hemline respectively forming smoothly transitioning arc-shaped protrusions, the two side seams of the back piece being straight segments; wherein, the two side seams of the front piece and the two side seams of the stretched back piece are aligned one by one and sewn together to form a three-dimensional space inside the top body for abdominal shaping.
[0007] The chest circumference values of the front piece and the back piece are both first values, and the hem circumference values of the front piece and the back piece are both second values. The first value is less than the second value, and the difference between the first value and the second value is 1-2cm.
[0008] The length of the front piece is greater than the length of the back piece, and the difference in allowance between the lengths of the front piece and the back piece is 0.008 * fabric weight (g / m²) + 0.2cm.
[0009] The allowance difference between the length of the front piece and the length of the rear piece is in the range of 1.4-2.2 cm.
[0010] The waistline position of the front piece is the position after adding a set value along the direction close to the hem of the front piece, starting from the shoulder and neck point of the front piece. The set value is 1 / 4 of the human body height + 8cm.
[0011] The seams on both sides of the front piece extend 0.3-0.7cm from the waistline.
[0012] The main body of the garment is made of knitted fabric formed by plain weave or pique knit.
[0013] The weight of the knitted fabric is 180-250 g / m².
[0014] Both the front piece and the rear piece are A-shaped.
[0015] With the above structure, this utility model has the following beneficial effects: The utility model adopts a design where the hem of the upper body is larger than the bust circumference, making the upper body A-shaped. This slightly flared hem can distract visual attention. Combined with the two side seams of the front piece forming protrusions at the waist and abdomen line, so that both side seams of the front piece are arc-shaped protrusions, the upper body after the front and back pieces are sewn together provides physical accommodation space in the weft direction at the abdomen position. That is, the upper body has three-dimensional space, thereby achieving the effect of concealing the protruding abdomen of the wearer and thus achieving a slimming and shaping effect.

Detailed Implementation
[0021] To further explain the technical solution of this utility model, the following detailed description is provided through specific embodiments.
[0022] This utility model provides a top with a tummy-covering structure, including a top body 100, which is suitable for making various types of tops, such as polo shirts, T-shirts, etc. In this embodiment, a polo shirt is used as an example for explanation.
[0023] For ease of description, the front side of the human body is the front side of the garment body 100, the opposite side is the back side, and the direction of the human body's height when wearing the garment is the length direction (i.e., longitudinal direction) of the garment body 100. The left side of the human body when wearing the garment is the left side of the garment body 100, and the right side is the right side of the garment body 100.
[0024] like Figure 2 As shown, the above-mentioned upper garment body 100 includes a front piece 1 and a back piece 2. Both the front piece 1 and the back piece 2 are A-shaped, and both sides of the front piece 1 and the back piece 2 are side seam edges, that is, the positions where the front piece 1 and the back piece are sewn together. In this embodiment, both sides of the front piece 1 are front side seam edges 11, and both sides of the back piece 2 are back side seam edges 21. The two front side seam edges 11 of the front piece 1 and the two back side seam edges 21 of the back piece 2 correspond one-to-one, and the two front side seam edges 11 of the front piece 1 have the same structure, and the two back side seam edges 21 of the back piece 2 have the same structure. Therefore, the front side seam edge 11 on the right side of the front piece 1 is... The structure of the back seam 21 on the right side of the back piece 2 will be described below. The front seam 11 of the front piece 1 extends to the right corresponding to the waistline 33 to form a protrusion 4. That is, based on the A-shaped pattern, the front seam of the front piece 1 is adjusted so that the front seam 11 on the left side of the front piece 1 forms an arc-shaped protrusion corresponding to the line segment between the bust line 31 and the protrusion 4, and the line segment between the protrusion 4 and the hemline 32. The two arc-shaped protrusions are smoothly transitioned. Preferably, the front piece 1 is still A-shaped after adjustment. In this embodiment, the back seam 21 of the back piece 2 is a straight line segment 42. In this way, the side seams of the front piece 1 and the back piece 2 adopt the above structure, which can provide a space for the abdomen in the weft direction (left and right direction) inside the subsequently sewn upper body 100. That is, the upper body 100 has a physical space reserved inside to accommodate the wearer's abdomen.
[0025] To elaborate further, the waistline position 33 of the front piece 1 refers to the position after adding a set value C along the direction close to the lower hem of the front piece 1, starting from the shoulder and neck point 34 of the front piece 1. The set value C is 1 / 4 of the human body height + 8cm.
[0026] Furthermore, the two front side seams 11 of the aforementioned front piece 1 extend by 0.3-0.7cm respectively to the waistline 33, preferably by 0.5cm; wherein, the specific extension amount is set according to the actual size and pattern of the garment body 100, and is not limited to the above-mentioned extension amount.
[0027] The front piece 1 and the back piece 2 have the same bust circumference and the same hem circumference. The bust circumference of the front piece 1 and the back piece 2 is smaller than the hem circumference of the front piece 1 and the back piece 2, so that the front piece 1 and the back piece 2 both present the aforementioned small A-shape. In this embodiment, the bust circumference values of the front piece 1 and the back piece 2 are both first values, denoted as L1, and the hem circumference values of the front piece and the back piece are both second values, denoted as L2. The first value L1 is smaller than the second value L2, and the difference between the first value L1 and the second value L2 is in the range of 1-2cm. Preferably, the difference between the first value L1 and the second value L2 is in the range of 1cm, that is, the ratio of the first value L1 to the second value L2 is 1:1.01. In this way, after the front piece 1 and the back piece are sewn together, the upper body 100 presents a small A-shape, so that the hem of the upper body 100 is slightly flared to distract visual attention.
[0028] The length of the front piece 1 corresponding to the distance between the bust line 31 and the hem line 32 is denoted as L3; the length of the back piece 2 corresponding to the distance between the bust line 31 and the hem line 32 is denoted as L4. In this embodiment, the length of the front piece L3 is greater than the length of the back piece L4. The difference between the length of the front piece L3 and the length of the back piece L4 is the allowance difference. The allowance difference = 0.008 * fabric weight (g / m²) + 0.2cm. Specifically, in the size of a regular top body, the range of the allowance difference between the length of the front piece L3 and the length of the back piece L4 is 1.5-2.5cm. That is, the allowance difference is adjusted according to the weight of the fabric used to make the top body 100. The heavier the weight, the greater the lengthening of the front piece 1 (i.e., the allowance difference).
[0029] In this way, by using a front piece length L3 that is greater than the back piece length L4, a basic allowance is provided for the amount of fabric used during the sewing process, thereby ensuring that the amount of fabric used is evenly distributed. This allows the finished garment body 100 to have a three-dimensional space for concealed embellishment at the abdomen. In other words, after the front seam edge 11 of the front piece 1 and the back seam edge 21 of the stretched back piece 2 are aligned with each other, the garment body 100 is sewn along the side seam edge to form the aforementioned three-dimensional space for abdominal embellishment inside.
[0030] In this embodiment, the above-mentioned upper garment body 100 is made of knitted fabric, and the knitted fabric is woven using conventional plain weave or pique weave; in this way, it can be ensured that the upper garment body 100 can be flat and stretched after the following weight of ironing.
[0031] Furthermore, in this embodiment, the weight of the knitted fabric is 180-150 g / m², thereby ensuring that the garment body made of the knitted fabric is not easily deformed and is easy to iron.
[0032] This utility model also provides a method for making a top, which adopts the aforementioned top with a belly-covering structure, and includes the following steps:
[0033] S1. Cutting: Cut the knitted fabric into front piece 1 and back piece 2 in a POLO style.
[0034] The front piece 1 is made by cutting the knitted fabric according to the structure of the aforementioned front piece 1, and the back piece 2 is made by cutting the knitted fabric according to the structure of the aforementioned back piece 2. In other words, both the front piece 1 and the back piece 2 are A-shaped, and the two front side seams 11 of the front piece 1 are both curved convex sections, while the two back side seams of the back piece 1 are both straight sections; furthermore, the bust circumference of both the front piece 1 and the back piece 2 is smaller than the hem circumference.
[0035] S2. Sewing: S2-1. In the flat state, the front piece 1 and the back piece 2 are sewn together, and the outer sides of the front piece 1 and the back piece 2 are attached to each other. In other words, the outer side of the back piece 2 is superimposed on the outer side of the front piece 1, and the outer sides of the two overlap each other. At the same time, the two back seam edges 21 of the back piece 2 are aligned one-to-one with the two front seam edges 11 of the front piece 1.
[0036] To elaborate further, the hem endpoint 51 here refers to the endpoint of the side seam of the front piece 1 or the back piece 2 corresponding to the hemline, and the bottom endpoint 52 refers to the position of the armhole bottom.
[0037] To elaborate further, the seam here refers to the back piece 2 being overlapped on the outer surface of the front piece 1, with the two pieces facing each other.
[0038] S2-2. Apply a stretching force along the length of the back piece 2 to match the stretching length of the back piece 2 with the aforementioned allowance difference, so that the two back seam edges 21 of the back piece 2 are completely overlapped with the corresponding front seam edges 11 of the front piece 1. At this time, the lower hem endpoints 51 of the two back seam edges 21 of the back piece 2 are aligned with the lower hem endpoints 51 of the corresponding front seam edges 11 of the front piece 1, and the bottom end endpoints 52 of the two back seam edges 21 of the back piece 2 are aligned with the bottom end endpoints 52 of the corresponding back seam edges 21 of the front piece 1, so as to form a sewn top with aligned seams.
[0039] S2-3. Use a four-thread overlock sewing machine to sew the top to be sewn together, taking in the excess difference of the front piece 1, so as to form the top body with pleats.
[0040] It should be noted that the above-mentioned four-thread overlock sewing machine is a four-thread overlock sewing machine that is already available on the market, so it will not be described in detail here.
[0041] S3. High-temperature ironing and shaping: Use a steam iron at a temperature range of 150-180℃ to apply pressure of 3-4 kg / cm² along both sides of the seam of the garment body 100 for 8-12 seconds to completely eliminate wrinkles and create a three-dimensional space inside the garment body 100.
[0042] It should be noted that the side seam boning mentioned here refers to the boning formed after the side seams of the front piece 1 and the back piece 2 are sewn together, and the side seam boning of the bodice body 100.
[0043] Furthermore, the temperature, pressure, and ironing time of the steam iron for the pleated upper garment body 100 produced in steps S2-4 can be set according to the actual situation and are not limited here.
[0044] For example, the main body of the shirt 100 is a polo shirt. The standard size of the main body of the shirt 100 is size L, which is suitable for heights of 170-175cm. The parameters of the main body of the shirt 100 are shown in Table 1.
[0045]
[0046] In this embodiment, the garment body 100 is made using the parameters in Table 1, such as... Figure 3 As shown, A is a schematic diagram of wearing the upper body 100 of this utility model, and B is a schematic diagram of wearing a traditional polo shirt. In this embodiment, the visibility of the wearer's abdominal protrusion is reduced by more than 60%. In addition, after 30 wash tests, the side seam flatness error of the upper body 100 is ≤1.2mm, while the industry standard is ≤1.5mm.
[0047] This utility model discloses a top with a belly-covering structure and its manufacturing method. The top body has an A-line shape, with the hem circumference larger than the bust circumference. The two front seam edges 11 of the front piece are both curved convex sections. This ensures that after the front piece 1 and back piece 2 are sewn together to form the top body 100, a three-dimensional space is created within the abdominal area to conceal the wearer's abdomen (belly area). Simultaneously, the hem of the top body has a visually dispersing effect, further concealing the abdomen and creating a slimming effect. Furthermore, by making the front piece of the front piece 1 longer than the back piece of the back piece 2, the front seam 11 of the front piece 1 and the stretched back seam 21 of the back piece 2 overlap. This solves the problem of controlling the fabric's weight during the sewing process of the front piece 1 and back piece 2, and high-temperature setting ensures the flatness of the top body 100.
[0048] The above description is only a preferred embodiment of this invention. All equivalent changes and modifications made within the scope of the claims of this utility model shall fall within the scope of the claims of this utility model.
