Abstract
Description
Technical Field
[0001] This application relates to the field of knitted garment shaping technology, specifically to a method for preparing a fully-shaped pressure-cushioned bra. Background Technology
[0002] With economic development and societal progress, consumers are becoming increasingly discerning in their clothing choices, and bras have become an essential part of women's daily attire. Knitted bras dominate the market due to their close fit, breathability, and comfort. However, most current bra manufacturing methods involve cutting and sewing, which can cause discomfort due to repeated friction at the seams. Furthermore, these bras are labor-intensive and resource-intensive to produce. Some bras emphasize a seamless, close-fitting design, utilizing seamless conformal cutting and bonding techniques. However, these methods inevitably result in high production costs and low efficiency during the cutting and bonding processes.
[0003] Patent CN114698880A discloses a processing method for seamless inner cup women's underwear and the underwear itself. The underwear first uses a seamless underwear machine to weave inner and outer pieces, then uses hot pressing and hot-melt adhesive to fix the inner and outer pieces and the molded cups; finally, the edges between the outer and inner pieces are sewn together, and the shoulder straps are processed. Although the inner and outer pieces woven using a seamless underwear machine do not require cutting and achieve a double-layer structure for the underwear, the manufacturing process is complex. The hot pressing and edging processes increase production costs, and the presence of hot-melt adhesive reduces the comfort of wearing the underwear.
[0004] With the development of computerized flat knitting machines and full-featured knitting technology, knitted bras made by full-featured knitting technology have gradually entered the public eye. However, due to the limitations of equipment and knitting principles, conventional methods cannot achieve the knitting of a three-layer structure, consisting of a double-layer chest structure and a single-layer back structure, on a single needle bed.
[0005] Patent CN112553761B discloses a fully-formed sports bra and its knitting method. This method achieves full-needle knitting of a double-layer structure, but it uses a separate knitting method for the front and back pieces, failing to achieve the effect of knitting three layers on a single needle bed. Furthermore, the double-layer structure of the sports bra's chest area is the entire front piece, resulting in poor fit to the chest and causing discomfort when worn. Summary of the Invention
[0006] This application provides a method for preparing a fully formed pressure-cushioning bra, which can solve the technical problem of making a pressure-cushioning bra through fully formed knitting.
[0007] This application provides a method for manufacturing a fully molded pressure-cushioning bra. The fully molded pressure-cushioning bra of this invention is woven from bottom to top, specifically as follows:
[0008] Step S1: First, use the cylindrical knitting method and a No. 1 yarn feeder to knit the underband P1 of the bra;
[0009] Step S2: Then, using the method of multiple partial knitting, continuously knit the outer part of the back piece and the front piece with yarn feeder No. 1, and knit the center part of the front piece with yarn feeder No. 2, leaving space for the chest area;
[0010] Step S3: Next, using the partial knitting method, use yarn feeders No. 1 and No. 2 to knit the left and right breast pad parts P3 with pressure cushioning function respectively;
[0011] Step S4: Finally, using a No. 2 yarn feeder, weave the shoulder straps and the connection between the shoulder straps and the garment body, P4.
[0012] Further, the specific method for reserving the chest position in step S2 is as follows: (1) Knit the front and back pieces of the garment body with the same structure on the front and back knitting beds; (2) By setting function lines, prevent the loops on the back knitting bed from turning to the front upper knitting bed, and retain the loops on the back knitting bed; (3) According to the shape outline of the chest, gradually turn the loops on the back knitting bed to the front knitting bed to form the chest structure, with a hollow reservation; (4) Use No. 2 yarn feeder to knit the reserved gap of the chest pad part by partial knitting; (5) Knit the front and back pieces of the garment body with the same structure on the front and back knitting beds.
[0013] Furthermore, when knitting the double-layered chest pad portion P3, the process includes: when knitting the outer layer loops, knitting one row using a method of one front bed knitting and one tuck stitch, then knitting a cycle of one tuck stitch and one front bed knitting stitch, offset from the previous row, to form a full front bed knitting row; when knitting the inner layer loops, knitting one row using a method of one back bed knitting and one tuck stitch, then knitting a cycle of one tuck stitch and one back bed knitting stitch, offset from the previous row, to form a full back bed knitting row.
[0014] Furthermore, the bra pad portion of the thickened knitting structure includes: first knitting one stitch on the back bed, then gathering stitches on the front bed, and repeating the back bed knitting and front bed gathering stitches at fixed intervals of n. The next row of knitting is offset from the previous row by one stitch position, and knitting 4 (n+1) rows constitutes one cycle.
[0015] Furthermore, the bottom portion P1 adopts a septum air layer structure, forming a septum structure with a total of four layers from front to back.
[0016] Furthermore, a transfer loop structure is incorporated during the knitting process to create breathable holes at designated locations on the bra, which is often used in sports bras.
[0017] Furthermore, during the weaving of the garment body P2.1 in step S2, a transfer loop structure is added to form breathable holes at designated locations on the bra.
[0018] Furthermore, in step S3, the inner layer of the double-layer structure of the breast pad is pre-stitched with pins at the top 1-2 cm to form an opening for inserting the breast pad.
[0019] The technical solution of this application has at least the following advantages:
[0020] (1) The present invention provides a method for preparing a fully formed pressure-cushioning bra, which realizes that the bra has a double-layer structure, can add breast pads, or make the bra have a suitable thickness, so as to directly play a protective role.
[0021] (2) The present invention adopts the full needle knitting method and realizes true three-layer knitting through a four-needle bed computer flat knitting machine. The resulting fabric is tighter and thicker than the fabric knitted with intermittent needles, and plays a supporting and protective role for the chest.
[0022] (3) The present invention adopts a fully formed weaving method, which not only makes the bra one piece, shortens the bra weaving process, greatly reduces manpower and material costs, but also provides more possibilities for the functional design of the bra while improving the comfort of wearing it.

[0029] The technical solutions of this application will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this application. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.
[0030] See Figure 1 This is a schematic diagram illustrating the manufacturing method of a fully molded pressure-cushioning bra. The fully molded pressure-cushioning bra of this invention is woven from bottom to top, specifically as follows:
[0031] Step S1: First, use the cylindrical knitting method and No. 1 yarn to knit the underband P1 of the bra. The underband P1 uses a spaced-needle air layer structure to form a four-layer spaced-needle structure in the front and back.
[0032] Step S2: Using multiple partial knitting methods, knit single-layer garment body parts P2.1 and P2.2 using yarn feeder No. 1 and yarn feeder No. 2, and reserve the position of the bra; the specific method is as follows: (1) Knit the front and back pieces of the garment body with the same structure on the front and back knitting beds; (2) By setting the function line, prevent the loops on the back knitting bed from turning to the front upper knitting bed, and retain the loops on the back knitting bed; (3) According to the shape of the chest, gradually turn the loops on the back knitting bed to the front knitting bed to form the chest structure, and reserve the hollow part; (4) Using yarn feeder No. 2, knit the reserved gap of the chest pad part using partial knitting; (5) Knit the front and back pieces of the garment body with the same structure on the front and back knitting beds;
[0033] Step S3: Next, using a partial knitting method, weave the double-layered breast pad part P3 using yarn feeders No. 1 and No. 2;
[0034] Step S4: Finally, using a No. 2 yarn feeder, weave the shoulder straps and the connection between the shoulder straps and the garment body, P4.
[0035] The breast pad portion P3 is a double-layered structure knitted with full stitches. There are two specific methods for its construction. The first method involves knitting a double-layered structure, see [link to documentation]. Figure 2 First, knit four rows as the base, as shown in (a) to (d). The first row is knitted in a loop of "front knit - back knit". The second row is knitted in a staggered loop of "back knit - front knit". The third row is knitted in a staggered loop of "back knit - front knit". The fourth row is knitted in a staggered loop of "front knit - back knit". These four rows complete the base work for the double-layer knitting. Next, knit one row of the outer chest structure. When knitting the outer layer loops, knit one row using the method of one stitch knitted at the front bed and one stitch knitted. Then, knit one stitch knitted and one stitch knitted at the front bed in a staggered loop with the previous row, thus forming a row of full stitch knitted at the front bed. Finally, weave a row for the inner chest structure. When knitting the inner layer loops, use a pattern of one stitch for the back bed and one stitch for the tuck loop to knit one row, then repeat this cycle of one stitch for the tuck loop and one stitch for the back bed, offset from the previous row, to create a full back bed row. These two rows form a complete four-needle full stitch knit row, compensating for the limitation of four-needle flat knitting machines in not being able to knit a four-needle structure. Then, alternate between the inner and outer layers until the inner layer opening. Perform a cross stitch 1-2cm from the top of the inner layer to create an opening for the breast pad. Continue knitting the outer layer until finished. During the knitting process, a feeder can be added to feed in different yarn materials, giving the inner and outer layers of the bra different wearing properties.
[0036] The second type is a knitted structure with thickened breast pads, see [link / reference]. Figure 3 , Figure 3 The diagram shows a thickened structure with smaller intervals and thinner thickness. It indicates that after a gap of one stitch, one stitch is first knitted on the back bed, then gathered on the front bed, then skipped by one stitch, and the back bed knitting and front bed gathering are repeated. The next row is knitted one stitch away from the previous row. After knitting the back bed round and the front bed gathering, the same method is used to knit the front bed round and the back bed gathering.
[0037] If the number of empty stitches between intervals is n, then a cycle is formed by knitting 4 (n+1) rows. The value of the number of stitches n determines the thickness of the bra area; the larger n is, the thicker the bra area.
[0038] Example 1: A fully molded bra with a double-layered chest structure
[0039] See Figure 4The bra's shoulder straps 4-1 are woven with a low-density single-sided plain knit weave, making the shoulder straps thin and preventing them from easily deforming due to washing or other reasons. The right bust 4-4 and left bust 4-5 of the bra have a double-layer structure with full-needle knitting. The right bust opening 4-2 and left bust opening 4-3 are obtained by pre-knitting the inner layer of the full-needle knitted air layer. In actual wear, inserting breast pads on both sides can achieve pressure cushioning. The bra's underband 4-6 is woven with a spaced-needle air layer structure, forming a four-layer spaced-needle structure in the front and back, which has better stability and is not easy to deform or shift during wear. The bra body is woven with a normal-density single-sided plain knit weave, making the body lighter and more comfortable, suitable for summer wear.
[0040] Example 2: A fully molded sports bra with thickened breast pads
[0041] See Figure 5 The shoulder straps 5-1 of the sports bra are woven with a perforated air layer, providing greater support and lift to the chest. The breast pads 5-2 of the sports bra have a thickened structure and are woven in one piece. The underband 5-3 of the sports bra is woven with a perforated air layer, incorporating an elastic yarn during the weaving process to make the underband more stable, more elastic, and provide better support to the chest. The body of the sports bra 5-4 is woven with a plain weave fabric, with the outer layer incorporating moisture-wicking yarn and the inner layer made of quick-drying yarn. Regularly spaced ventilation holes 5-5 are formed in the middle of the back using a double-sided transfer loop weave, enhancing breathability during exercise.
[0042] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the scope of protection of this application.
