Bottom shirt with built-in integrally-formed bra

Abstract

The utility model discloses a bottoming shirt with a built-in integrally-formed bra, which comprises a front piece, a rear piece opposite to the front piece, a connecting part positioned below the front piece and the rear piece and arranged in a whole circle, and a suspender connecting the front piece and the rear piece, and the front piece, the rear piece, the connecting part and the suspender are formed by knitting 40D nylon yarns. The elongation rate of the front piece fabric is 15-20% larger than that of the suspender fabric. By adopting the structure, the three-dimensional forming of the bra part is realized by adopting a circular knitting machine after reverse compensation calculation by precisely measuring the difference between the expansion and contraction rates of the two fabrics (the elongation rate of the sleeping bra fabric is 15-20% higher than that of a suspender).

Description

Technical Field

[0001] This utility model relates to a base layer for a concealed one-piece molded bra, and more particularly to a base layer for a concealed one-piece molded bra with good skin-fitting effect. Background Technology

[0002] One-piece molding (such as the circular knitting one-piece molding of sleep bras) and sewing (such as the sewing of fabric together for camisoles) are two completely different manufacturing methods. Both the bra and camisole parts are made using sewing. However, because the strong elasticity of the sleep bra differs significantly from the elasticity of the outer fabric, if the elasticity characteristics of the two fabrics are not accurately grasped during the pattern-making stage, the joining process will be difficult to complete smoothly. Furthermore, even a 3mm difference in size between the sleep bra and the outer fabric during joining can easily cause the outer fabric to loosen.

[0003] When bras are made using a one-piece molding process, the bra section and the outer fabric (strap section) must be woven simultaneously, forcing them to be made of the same material. Even if you are not satisfied with the outer fabric, you cannot change it to another material. When the strap section and the bra are made of the same material, the straps may become too elastic and may highlight the material's unique luster (such as the plastic texture of synthetic fibers), thus ruining the overall design aesthetics. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a base layer with an integrated bra that has a good skin-fitting effect.

[0005] To solve the above-mentioned technical problems, the technical solution of this utility model is as follows: a base layer for a concealed one-piece molded bra, the innovation of which is that the base layer for the concealed one-piece molded bra includes a front piece, a back piece directly opposite the front piece, a connecting part located below the front piece and the back piece and arranged in a circle, and a strap connecting the front piece and the back piece. The front piece, the back piece, the connecting part and the strap are all knitted from 40D nylon yarn, and the elongation of the front piece fabric is 15-20% greater than that of the strap fabric.

[0006] Preferably, the front piece includes a left chest support portion, a right chest support portion, and a connecting portion connecting the left chest support portion and the right chest support portion, wherein both the left chest support portion and the right chest support portion are formed by three-dimensional knitting using a circular knitting machine.

[0007] Preferably, the connecting portion includes a first part located on the left side of the left chest support, a second part located between the left chest support and the right chest support, and a third part located on the right side of the right chest support. The connecting portion also includes a fourth part located between the left chest support, the right chest support, and the connecting portion. The fourth part is connected to the first part, the left chest support, the second connecting portion, the right chest support, and the third connecting portion, respectively.

[0008] Preferably, the connecting part adopts a knitting pattern of one stitch and three stitches skipped.

[0009] Preferably, the connecting part adopts a knitting pattern of one stitch and two stitches skipped.

[0010] Preferably, the elongation of the front fabric is 15% greater than that of the strap fabric.

[0011] Preferably, the suspenders retain 0.8-1.2% pre-shrinkage compensation during cutting.

[0012] Preferably, the suspenders retain 1% pre-shrinkage compensation during cutting.

[0013] The advantages of this invention are as follows: by adopting the above structure, by precisely measuring the difference in stretch rate between the two fabrics (the stretch rate of the sleep bra fabric is 15-20% higher than that of the strap), and after reverse compensation calculation, a circular knitting machine is used to achieve three-dimensional molding of the bra part. Attached Figure Description

[0014] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0015] Figure 1 This is a structural schematic diagram of a base layer for an integrated molded bra, which is part of this utility model.

[0016] In the diagram: 1-front piece, 11-left chest support, 12-right chest support, 131-first part, 132-second part, 133-third part, 134-fourth part, 2-back piece, 3-connecting part, 4-sling. Detailed Implementation

[0017] This utility model discloses a base layer for an integrated molded bra, comprising a front piece 1, a back piece 2 directly opposite the front piece 1, a connecting part 3 located below the front piece 1 and the back piece 2 and arranged in a complete circle, and straps 4 connecting the front piece 1 and the back piece 2. The front piece 1, back piece 2, connecting part 3, and straps 4 are all knitted from 40D nylon yarn. The elongation rate of the front piece 1 fabric is 15-20% greater than that of the straps 4 fabric. The 40D nylon yarn used in this utility model is 4030 yarn, which is thicker than 2030 yarn, and has approximately twice the spandex content of 2030 yarn. By adopting the above structure and precisely measuring the difference in stretch rate between the two fabrics (the elongation rate of the sleep bra fabric is 15-20% higher than that of the straps 4), and after reverse compensation calculation, a circular knitting machine is used to achieve the three-dimensional molding of the bra portion.

[0018] Compared with the traditional structure, this utility model eliminates the seam between the left chest support 11, the right chest support 12 and the connecting part in the front piece 1. The seam will have a slight wrinkling effect during the wearing process. Based on this, the connecting part adopts a knitting form of one stitch and three stitches to avoid the wrinkling effect.

[0019] The aforementioned front piece 1 includes a left chest support 11, a right chest support 12, and a connecting portion linking the left chest support 11 and the right chest support 12. Both the left chest support 11 and the right chest support 12 are formed using a circular knitting machine in three dimensions. The connecting portion includes a first part 131 located to the left of the left chest support 11, a second part 132 located between the left chest support 11 and the right chest support 12, and a third part 133 located to the right of the right chest support 12. The connecting portion also includes a fourth part 134 located between the left chest support 11, the right chest support 12, and the connecting portion 3. The fourth part 134 is connected to the first part 131, the left chest support 11, the second connecting portion 3, the right chest support 12, and the third connecting portion 3, respectively. The connecting portion area is a drop stitch knitted area. Increasing the proportion of drop stitch knitting will enhance the wearing pressure (unlike conventional plain knitting, the drop stitch process increases the fabric density and thickness by pulling the knit upwards).

[0020] The connecting part 3 of this utility model adopts a knitting pattern of one stitch and two stitches skipped (the larger the number, the stronger the tightness when worn). The elongation of the front piece 1 fabric is 15% greater than that of the suspender 4 fabric; the suspender 4 retains 0.8-1.2% pre-shrinkage compensation during cutting, preferably 1% pre-shrinkage compensation during cutting.

[0021] The preferred embodiments of the present invention disclosed above are merely illustrative of the invention and are not intended to limit the invention. Although the invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can make many modifications and variations to some of the technical features based on the content of this specification. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the invention should be included within the scope of protection of the invention.
