Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of body shaping products, in particular to a full-molding waistband main body and a molding method thereof. BACKGROUND

[0002] The waistband is an underwear that plays a shaping role on the waist and abdomen of the human body. It uses the combination of elastic and non-elastic materials to play a traction or restraint role on the waist and abdomen of the human body, so as to maintain or adjust the size and shape of the waist and abdomen of the human body, and meet the body shaping and beautifying needs of female users for slim waist curve and good waist-hip ratio.

[0003] In terms of structure, it generally includes a waistband main body and a connecting component located at both ends of the waistband main body. The connecting component is various, such as a belt, a row of buttons, or a magic tape, etc. If the waistband main body is single-layer, the shaping effect is general. Therefore, in order to enhance the body shaping strength of the waistband, some increase local shaping pieces by sewing on the basis of single-layer elastic fabric on the market, such as Chinese public literature (CN217906373U). This will increase the subsequent sewing process. Some others use multiple elastic ribbons or rubber between the surface single-layer fabric and the inner single-layer fabric, such as Chinese public literature (CN217310744U) and Chinese public literature (CN211185890U). The surface layer and the inner layer of this type of waistband also use elastic yarns. Since the rubber is glued and pasted, the elasticity of each layer needs to be considered to balance the stretching and rebound performance of each layer of the waistband. At the same time, the surface layer and the inner layer are required to be high-density and high-elastic, and the air permeability needs to be improved. After wearing for a long time, it is hot and uncomfortable, especially the sandwiched rubber is thick and heavy and has poor air permeability. SUMMARY

[0004] The purpose of the present application is to provide a full-molding waistband main body and a molding method thereof, which are simple to make, good in shaping, and comfortable and breathable to wear.

[0005] To achieve the above-mentioned purpose, the technical solution adopted by the present application is: The full-molding waistband main body is a piece of weft-knitted spacer fabric structure, which is fully molded by a surface layer, an inner layer, and a spacer layer connected between the surface layer and the inner layer. The spacer layer uses spandex elastic yarn, and the surface layer and the inner layer use yarn nylon or chinlon. The surface layer has a plain-knitted area and a loop transfer-knitted area, and the inner layer is entirely knitted as a plain-knitted structure.

[0006] Preferably, the spandex elastic yarn is spandex covered yarn.

[0007] Preferably, the spandex covered yarn is spandex single-covered yarn or spandex double-covered yarn.

[0008] Preferably, the two outer cover yarns of the spandex double-covered yarn have opposite twist directions.

[0009] Preferably, the loop transfer-knitted area is knitted as a leno-knitted structure.

[0011] Preferably, the color of the outer wrap yarn of the spandex cover yarn is different from the color of the yarn of the loop transfer knitting area of the surface layer, and the spandex cover yarn is exposed at the eyelet position.

[0012] Preferably, the spacer layer is connected with the surface layer and the back layer by tuck stitches or fabric layer connection.

[0013] The application also provides a forming method of a fully-formed waistband main body, including spacer fabric knitting of a flat knitting area and spacer fabric knitting of a loop transfer area. The spacer fabric knitting of the flat knitting area includes the following steps: the surface layer and the back layer are respectively knitted by using the front needle bed and the back needle bed; and the V-shaped spacer layer is obtained by tuck knitting every other needle on the front needle bed and the back needle bed, each row is staggered from the previous row by one stitch, and each flat knitting course connects one spacer yarn course by tuck. The spacer fabric knitting of the loop transfer area includes the following steps: the surface layer and the back layer are respectively knitted by using the front needle bed and the back needle bed, the surface layer is circularly knitted with two courses as a repeating unit, the stitches on the even needles of the first course are transferred to the odd needles of the adjacent needles, and the even needles of the second course are looped on the empty needles; and the V-shaped spacer layer is obtained by tuck knitting every other needle on the front needle bed and the back needle bed, each row is staggered from the previous row by one stitch, and each second course connects one spacer yarn course by tuck.

[0014] The application also provides a forming method of a fully-formed waistband main body, including spacer fabric knitting of a flat knitting area and spacer fabric knitting of a loop transfer area. The spacer fabric knitting of the flat knitting area includes the following steps: step S11, flat knitting N1 on the back needle bed and flat knitting N2 on the front needle bed; step S12, connecting course C1 of flat knitting on the back needle bed; step S13, knitting fabric layer L by using even needles on the back needle bed; step S14, loop transfer C2 of the last course of the fabric layer L to N2 of the front needle bed of step S11; and repeating steps S11-S14. The interval fabric weaving of the transfer loop weaving area comprises the following steps: step S21, weaving plain stitches N1 on the back needle bed and weaving said leno stitches N2, N3 on the front needle bed; step S22, weaving a connecting course C1 of plain stitches on the back needle bed; step S23, weaving a fabric layer L on the back needle bed by using even needles; step S24, transferring the last course C2 of the fabric layer L to the leno stitch N3 of the front needle bed of step S21; repeating steps S21-S24.
