Description

Technical Field

[0001] This utility model relates to the field of body shaping products technology, specifically to a body shaping waist belt with a fully molded main body. Background Technology

[0002] A shaping waist cincher is an undergarment that shapes the waist and abdomen. It uses a combination of elastic and non-elastic materials to pull or restrain the waist and abdomen, thereby maintaining or adjusting the size and shape of the waist and abdomen, and meeting the body shaping and beautifying needs of female users for a slim waist curve and a good waist-to-hip ratio.

[0003] Structurally, it generally includes a sheet-like main body and connecting components located at both ends of the sheet-like main body. The connecting components are diverse, including straps, buckles, or Velcro, etc. If the sheet-like main body is a single layer, the shaping effect is generally average. Therefore, in order to enhance the shaping power of the waist belt, some products on the market use additional plastic sheets sewn on a single layer of elastic fabric, such as Chinese public document (CN217906373U). This will increase the subsequent sewing process. Other products use multiple elastic strips or rubbers bonded between the outer single layer of fabric and the inner single layer of fabric, such as Chinese public documents (CN217310744U) and Chinese public document (CN211185890U). The outer and inner layers of this type of waist belt also need to use elastic yarns. Because of the adhesive bonding, the elasticity of each layer must be considered to balance the stretching and rebound performance of each layer of the waist belt. At the same time, the outer and inner layers are required to be high-density and high-elasticity, and the breathability needs to be improved. Wearing it for a long time will make it stuffy and uncomfortable, especially the interlayer rubber, which is thicker, heavier and has poor breathability. Utility Model Content

[0004] The purpose of this invention is to provide a body shaping waist belt that is fully molded, simple to manufacture, has good shaping properties, and is comfortable and breathable to wear.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: The body-shaping waistband with a fully formed main body includes a sheet-like main body and connecting components that are connected to both ends of the sheet-like main body and cooperate with each other. The sheet-like main body is a weft-knitted spacer fabric with a fully formed main body, an inner layer, and a spacer layer connecting the main body and the inner layer. The spacer layer is made of spandex elastic yarn, while the main body and the inner layer are made of yarn without spandex. The main body has a plain knitting area and a transfer knitting area. The transfer knitting area produces eyelets at the transfer points.

[0006] Preferably, the connecting component is a Velcro strap, zipper, snap fastener, or tie.

[0007] Preferably, a shaping bone is attached and fixed to the inner surface of the inner layer of the sheet-like main body.

[0008] Preferably, the shaping bone is glue bone or steel bone.

[0009] Preferably, the shaping bone is hot-pressed onto the inner surface of the sheet-like body using a hot-melt adhesive liner, which encapsulates the shaping bone.

[0010] Preferably, the hot melt adhesive backing comprises a hot melt adhesive layer and a fleece layer bonded together, the hot melt adhesive layer being hot-pressed to the sheet-like body, and the surface of the fleece layer away from the hot melt adhesive layer having a nap.

[0011] Preferably, the spandex elastic yarn is spandex-covered yarn.

[0012] Preferably, the spandex elastic yarn is a single-covered spandex yarn or a double-covered spandex yarn.

[0013] Preferably, the core yarn of the spandex-covered yarn is 100D-500D spandex.

[0014] Preferably, the outer covering yarn of the spandex-coated yarn is nylon filament or polyester filament.

[0015] Preferably, the fineness of the outer yarn is 100D-500D.

[0016] Preferably, the two outer yarns of the spandex double-wrapped yarn have opposite twist directions.

[0017] Preferably, both the outer and inner layers are made of polyester or nylon yarn.

[0018] Preferably, the inner layer is entirely woven with a plain knit pattern.

[0019] Preferably, the loop-shifting weaving area is woven with a leno fabric.

[0020] Preferably, the leno weave is woven in a repeating cycle with two horizontal rows as repeating units. The loops on the even-numbered needles of the first horizontal row are transferred to the odd-numbered needles of the adjacent needles, and the even-numbered needles of the second horizontal row are padded with yarn to form loops on the empty needles.

[0021] Preferably, the spandex elastic yarn is spandex covered yarn, the color of the outer yarn of the spandex covered yarn is different from the color of the yarn in the surface transfer knitting area, and the spandex covered yarn is exposed at the eyelet position in the transfer knitting area.

[0022] Preferably, the spacer layer is connected to the outer and inner layers by loop fastening or by a fabric layer.

[0023] Compared with the prior art, the present invention has the following beneficial effects: The main body of this body shaping waist belt adopts a one-piece structure of weft-knitted spacer fabric. The outer layer, inner layer and spacer layer can be seamlessly woven in one piece by computer flat knitting machine. There is no need for subsequent sewing or gluing processes. The finished product can be directly assembled and connected. It is simple to manufacture and has few processes.

[0024] In addition, the spacer layer uses spandex elastic yarn while the outer and inner layers use yarns without spandex. This concentrates the binding force generated by the stretching and rebound in the spacer layer. Coarse denier spandex has high elasticity and good shaping or support strength. The main area of ​​the outer layer and the inner layer use plain knit weave that deforms after transverse stretching, which can significantly reduce the interference and adverse effects of the outer and inner layers on the stretching and recovery of the spacer layer. At the same time, the spacer layer can be used to drive the stretching and recovery of the outer and inner layers.

[0025] Furthermore, the surface layer has a shifted loop knitting area, which creates an eyelet effect. The eyelets can effectively expose the spacer layer yarns, and the use of different colors between the spacer layer and the surface layer yarns achieves a decorative visual effect. At the same time, combined with the lateral stretching and deformation of the inner layer of the waistband, the breathability and moisture permeability of the shifted loop knitting area can be significantly enhanced, making it more comfortable to wear.

Detailed Implementation

[0039] To make the above-mentioned features and advantages of this utility model more apparent and understandable, specific embodiments are described below in conjunction with the accompanying drawings for detailed explanation.

[0040] like Figures 1-2 As shown, this embodiment provides a fully molded body shaping waistband, including a sheet-like main body 100 and connecting components 200 connected to both ends of the sheet-like main body 100 and cooperating with each other. The waistband can be wrapped around the user's waist through the connecting components 200 and the binding force generated after the sheet-like main body 100 is stretched can be used to apply a shaping or supporting effect to the waist.

[0041] Regarding the connecting component 200, there are several implementation schemes, the most common being the use of Velcro, where Velcro components are fixedly installed at both ends of the sheet-like main body 100, such as... Figure 3 As shown, the hook and loop fastener assembly includes a central shaping sheet 201 and hot-melt adhesive backing sheets 202 that are hot-pressed onto the front and rear sides of the central shaping sheet 201. The outer surface of the hot-melt adhesive backing sheets 202 away from the central shaping sheet 201 is brushed to obtain a pile surface 203. The ends of the hot-melt adhesive backing sheets 202 near the sheet-like body 100 are all hot-pressed together with the sheet-like body 100. One of the hook and loop fastener assemblies has a hook face sheet 204 of nylon hook and loop fastener glued to its surface. When the hook face sheet 204 of nylon hook and loop fastener is close to the pile surface 203 on the other hook and loop fastener assembly, they are fastened together. Since the pile surface 203 has a length along the length direction of the sheet-like body 100, the tightness of the waistband can be adjusted by adjusting the hook face sheet 204 at different length positions of the pile surface 203. To enhance the connection between the Velcro assembly and the sheet body 100, the hot melt adhesive backing 202 can be further sewn to the sheet body 100 at the end by stitching, while the intermediate shaping sheet 201 is generally made of nylon plastic sheet.

[0042] In other examples, the connecting component 200 can also be replaced with a zipper, snap buttons, or straps. Zippers and snap buttons are also common accessories in shapewear, allowing for opening and closing control between two items or at both ends or openings of the same item.

[0043] In this embodiment, the sheet-like main body 100 is a weft-knitted spacer fabric formed by a computerized flat knitting machine. It consists of a surface layer 101, an inner layer 102, and a spacer layer 103 connecting the surface layer 101 and the inner layer 102. The spacer layer 103 is a double-wrapped spandex yarn consisting of a 400D spandex core yarn wrapped with two 420D / 266F nylon filaments twisted in opposite directions. Both the surface layer 101 and the inner layer 102 are made of 240D / 180F nylon filaments. In other examples, the spacer yarn used in the spacer layer 103 can also be a single-wrapped spandex yarn, such as a 200D-500D spandex core yarn wrapped with a 200D-500D nylon filament. The outer wrapping yarn can also be replaced with polyester filament. The use of coarse denier spandex helps enhance the lateral tensile resilience of the waistband, conforming to the waist and achieving a mechanical support effect.

[0044] In this embodiment, the outer layer 101 is divided into a plain knit area 1011 and a loop knit area 1012. The plain knit area 1011 is knitted as a plain knit structure, and the loop knit area 1012 is knitted as a leather structure. The inner layer 102 is entirely knitted as a plain knit structure, and the spacer layer 103 is connected to the outer layer 101 and the inner layer 102 by loop knitting, such as... Figure 5 As shown.

[0045] The gauze weave can be designed in various ways according to pattern requirements. Specifically, in this embodiment, it is woven in a repeating cycle with two horizontal columns as the repeating unit, such as... Figure 8 As shown, the loops on even-numbered needles 2, 4, 6, 8, and 10 of the first row are transferred to odd-numbered needles 3, 5, 7, 9, and 11 of the adjacent needles. In the second row, even-numbered needles 2, 4, 6, 8, and 10 form loops by padding yarn on empty needles. This loop transfer occurs on even-numbered needles and forms eyelets on them. The color of the outer yarn of the spandex-covered yarn differs from the yarn color of the loop-transfer weaving area 1012 of the surface layer 101. For example, the outer yarn is navy blue while the surface layer 101 yarn is light gray. The loop-transfer weaving area 1012 exposes the spandex-covered yarn at the eyelet positions, achieving a decorative visual effect. Simultaneously, the lateral stretching of the waistband enhances the moisture permeability and breathability of the loop-transfer weaving area 1012. The second row of the leno weave serves as the row for loop connection or loop transfer weaving with the spacer layer 103.

[0046] During knitting, first use the front needle bed and back needle bed to knit the outer layer 101 and inner layer 102 respectively. Then, knit in tuck stitches on the front and back needle beds, alternating stitches to obtain a V-shaped spacer layer L, with each row offset by one loop from the previous row. Figure 6 This is a diagram showing the weaving process of the spacer fabric corresponding to the plain knit area 1011 of the surface layer 101. Figure 7This is a diagram showing the knitting process of the spacer fabric corresponding to the transfer knitting area 1012 of the outer layer 101. In the diagram, F1 represents the outer layer, F2 represents the inner layer, and L represents the spacer layer. The horizontal density of the outer layer 101 and the inner layer 102 is 60-80 threads / 10cm, and the vertical density is also 60-80 threads / 10cm. In the plain knitting area 1011, each plain knitting row is connected to a spacer yarn row by a tucked loop. In the transfer knitting area 1012, each row II is connected to a spacer yarn row by a tucked loop.

[0047] To maintain the waistband's firmness and prevent curling during use, this embodiment further includes a shaping frame 301 fixedly attached to the inner surface of the inner layer 102 of the sheet-like main body 100. The shaping frame 301 is either glued or made of steel, and there are three shaping frames 301 arranged on the left, center, and right. The shaping frames 301 are hot-pressed to the inner surface of the inner layer 102 of the sheet-like main body 100 using a hot-melt adhesive backing. Figure 4 As shown, the hot melt adhesive liner encapsulates the shaping bone 301. The hot melt adhesive liner includes a hot melt adhesive layer 302 and a fleece layer 303 bonded together. The hot melt adhesive layer 302 is hot-pressed to the sheet body 100. The surface of the fleece layer 303 away from the hot melt adhesive layer 302 has a nap to improve the feel of the touch.

[0048] It should also be noted that in some other examples, the spacer layer 103 can also be connected to the outer layer 101 and the inner layer 102 by a fabric layer, that is, the spacer layer 103 is woven into a fabric layer, such as... Figure 9 As shown, in this example, the yarn of the spacer layer 103 is a double-wrapped spandex yarn with a spandex fiber density of 100D-200D and an outer nylon yarn fiber density of 100D-250D.

[0049] like Figures 10-11 The diagram shows the knitting process of the spacer fabric connecting the fabric layers in the plain knitting area 1011. Step S11: Knit plain knitting N1 on the back needle bed and plain knitting N2 on the front needle bed; Step S12: Knit the connecting row C1 of the plain knitting on the back needle bed; Step S13: Knit fabric layer L on the back needle bed using an even number of needles; Step S14: Transfer the last row C2 of fabric layer L to N2 on the front needle bed in step S11; Repeat steps S11-S14.

[0050] like Figure 10 and Figure 12The diagram shows the knitting process of the spacer fabric connecting the fabric layers in the area of ​​the transfer knitting zone 1012. Step S21: Knit plain knit structure N1 on the back needle bed, and knit the above-mentioned leno structures N2 and N3 on the front needle bed; Step S22: Knit the connecting row C1 of the plain knit structure on the back needle bed; Step S23: Knit fabric layer L on the back needle bed using an even number of needles; Step S24: Transfer the last row C2 of fabric layer L to the leno structure N3 on the front needle bed of step S21; Repeat steps S21-S24.
