Description

Seven-piece garment body and seven-piece garment body assembly method Technical Field

[0001] The present application relates to the technical field of clothing, and in particular to a seven-piece clothing body and a method for assembling the seven-piece clothing body. Background Art

[0002] Currently, commonly used disposable non-woven garments on the market, such as isolation gowns and surgical gowns, are typically manufactured by dividing the fabric pieces into three, five, six, or other numbers of pieces. Specifically, the three-piece, five-piece, and six-piece garments each comprise at least a garment body and two cylindrical sleeves connected to either side of the body. During the actual manufacturing process of these garments, the fabric pieces must be manually sewn into a cylindrical shape and then attached to the sides of the garment body, or the T-shaped sleeve pieces must be sewn to the garment body and then assembled into the cylindrical sleeves. Due to the cylindrical shape of the sleeves and the soft nature of the non-woven fabric, automated assembly is difficult, requiring manual assembly. This results in low assembly efficiency and a low yield rate.

[0003] In addition, during the fabric usage statistics process, it was discovered that the existing V-shaped or olive-shaped joints between the sleeves and the body of the garment result in low fabric utilization and are more likely to cause fabric waste. The fabric needs to be cut separately for the front, back, and sleeves, a cumbersome cutting process that makes the entire garment manufacturing process inefficient. Specifically, each sleeve piece needs to be manually sewn to the body of the garment, which is inefficient and prone to quality issues such as leaking seams, skipped stitches, folds, dirt, and holes. Especially for medical supplies, the manual sewing process is complicated and, after multiple transfers, the product is easily contaminated and has a high bacterial count. Summary of the Invention

[0047] The “up” and “down” involved in the embodiments of the present application are based on the orientations shown in FIG. 3 and FIG. 9 .

[0048] The existing three-piece disposable non-woven isolation gown or disposable non-woven surgical gown is shown in Figure 1. As can be seen from the figure, the three-piece disposable non-woven isolation gown or disposable non-woven surgical gown includes a body and two sleeves. The body is composed of a complete main body fabric including the front and back of the body, and the sleeves are made of a fabric unfolded into a trapezoid. As shown in Figures 2 and 3, during production, the left and right sleeves are first combined into a cylindrical shape, and then the sleeves are sewn at the cuff. Alternatively, the sleeves are sewn from the wide parts of the left and right sleeves to the cuff of the body, and then sewn along the cuff to the shoulder to form the garment. Although the three pieces can be assembled to form a complete disposable non-woven isolation gown or disposable non-woven surgical gown, the main body of the gown has multiple irregular clothing connection openings, resulting in waste of fabric cut at the openings. At the same time, the main body of the gown is combined and assembled to form a complete gown. The preparation process of the gown is complicated, the production efficiency is low, and it is prone to quality problems and a high total colony count.

[0049] The existing five-piece disposable non-woven isolation gown or disposable non-woven surgical gown is shown in Figures 4 and 5, and includes a body front, a first body back, and a second body back, as well as a first sleeve and a second sleeve connected to both sides of the body front, wherein the body front is assembled correspondingly to the first body back and the second body back, the first sleeve and the second sleeve are cylindrical, and the connection between the first sleeve, the second sleeve and the body is set to an arc or V shape, or an olive shape, and then the sleeves are sewn at the cuff; or as shown in Figure 6, the left and right lower pieces of the sleeve are first sewn together, and then the sleeve width parts of the left and right pieces of the sleeve are sewn to the cuff of the body, and then sewn along the cuff to the shoulder to form a garment. In actual cutting, it is necessary to cut into a preset arc or V shape, or olive shape, and at the same time, manual sewing or welding is performed during assembly, which greatly increases the workload in the assembly process and reduces the production efficiency. Based on the above problems, this application proposes a seven-piece clothing body assembly method, which divides the fabric into seven pieces through scientific and reasonable analysis, saving fabric, making the assembly of the entire clothing more efficient and the quality more stable.

[0050] In a first embodiment, a method for assembling a seven-piece garment body is provided, as shown in Figures 7 and 8 , the method comprising the following steps:

[0051] Step S1: Cut the original fabric into a body front piece 1, a first body back piece 2, a second body back piece 3, a left sleeve upper piece 4, a left sleeve lower piece 5, a right sleeve upper piece 6 and a right sleeve lower piece 7.

[0052] Preferably, the clothing body in this embodiment includes but is not limited to disposable isolation gowns, disposable surgical gowns, hand-washing gowns, protective gowns and daily clothing.

[0053] Prepare original fabric, as shown in Figure 9, and cut the original fabric into seven pieces of preset shapes according to preset shapes and sizes, wherein the front piece 1 of the body is the same length as the first back piece 2 and the second back piece 3 of the body, the left sleeve upper piece 4 is the same length as the left sleeve lower piece 5 and has the same corresponding shape, the right sleeve upper piece 6 is the same length as the right sleeve lower piece 7 and has the same corresponding shape; at the same time, the left sleeve upper piece 4 is the same length as the back sleeve upper piece and has a symmetrical shape.

[0054] Step S2: Connect the left sleeve upper piece 4 to the left edge of the body front piece 1 , and connect the right sleeve upper piece 6 to the right edge of the body front piece 1 .

[0055] First, unfold the front body panel 1 and lay it flat, as shown in Figure 10. Then, symmetrically lay the left sleeve upper piece 4 and the right sleeve upper piece 6 on both sides of the front body panel 1, and make sure that one end of the left sleeve upper piece 4 and the right sleeve upper piece 6 extend a certain distance into the front body panel 1 to facilitate assembly and connection of the left sleeve upper piece 4 and the right sleeve upper piece 6 to the front body panel 1. The left sleeve upper piece 4 and the right sleeve upper piece 6 are assembled and connected along the edges where they overlap with the front body panel 1. Specific assembly methods include, but are not limited to, one or more of manual sewing, ultrasonic welding, high-frequency welding, hot pressing, and gluing.

[0056] Step S3: Connect the left sleeve lower piece 5 to the left edge of the first body back piece 2 , and connect the right sleeve lower piece 7 to the right edge of the second body back piece 3 .

[0057] Specifically, it includes: laying the front body piece 1 flat, and aligning the first back body piece 2 and the second back body piece 3 and laying them flat on the upper layer of the front body piece 1; wherein, the structures of the first back body piece 2 and the second back body piece 3 are shown in Figures 11 and 12.

[0058] As shown in Figure 13, align the left sleeve lower piece 5 with the left sleeve upper piece 4, and connect the left sleeve lower piece 5 to the first body back piece 2, align the right sleeve lower piece 7 with the right sleeve upper piece 6, and connect the right sleeve lower piece 7 to the second body back piece 3.

[0059] For example, as shown in Figure 14, after the connection between the body front piece 1 and the left sleeve upper piece 4 and the right sleeve upper piece 6 is completed, the first body back piece 2 and the second body back piece 3 are laid flat on both sides of the body front piece 1, so that a gap is provided between the first body back piece 2 and the second body back piece 3, and the left sleeve lower piece 5 and the right sleeve lower piece 7 are respectively connected to the side of the first body back piece 2 and the second body back piece 3 away from the central axis, and ensure that the side of the first body back piece 2 and the second body back piece 3 away from the gap are aligned with the two edges of the body front piece 1.

[0060] A gap is provided between the first back piece 2 and the second back piece 3, which greatly saves the time of putting on and taking off the protective clothing during use and improves the convenience of putting on and taking off the protective clothing.

[0061] Step S4: Lay the front body piece 1, the first back body piece 2 and the second back body piece 3 flat and align them, and assemble and connect them with the first back body piece 2 and the second back body piece 3 along the left and right edges of the front body piece 1 to form a seven-piece garment body.

[0062] As shown in Figure 15, the state in which the front body piece 1, the first back body piece 2, and the second back body piece 3 are stacked and aligned in step S3 is maintained. The left sleeve upper piece 4 is aligned with the left sleeve lower piece 5 and assembled along the edges of the left sleeve upper piece 4 and the left sleeve lower piece 5 to form the left sleeve. The right sleeve upper piece 6 is aligned with the right sleeve lower piece 7 and assembled along the edges of the right sleeve upper piece 6 and the left sleeve lower piece 5 to form the right sleeve. At the same time, the upper edges of the front body piece 1, the first back body piece 2, and the second back body piece 3 are assembled to form the assembly line at the collar of the disposable non-woven isolation gown or disposable non-woven surgical gown.

[0063] At the same time, as shown in Figures 15 and 16, the edges of both sides of the front body 1 are assembled from the lower part of the left sleeve to the lower edge of the front body 1 in the vertical direction, and are assembled along the lower part of the right sleeve to the lower edge of the front body 1 to form the assembly of both sides of the disposable non-woven isolation gown or the disposable non-woven surgical gown body.

[0064] In a specific embodiment, a neckline 8 is provided at the edges of the front body piece 1, the first back body piece 2, and the second back body piece 3, and the front and back of the front body piece 1, the first back body piece 2, and the second back body piece 3 at the neckline 8 are aligned. As shown in FIG13 , in order to improve the stability of the disposable non-woven isolation gown or disposable non-woven surgical gown on the user when the user performs other operations after wearing the disposable non-woven isolation gown or disposable non-woven surgical gown or the garment body, a strap 11 is assembled and connected to the first back body piece 2 and the second back body piece 3. Specifically, the size of the strap 11 is 4*180cm, and two points are set in the middle of the strap 11 to connect with the first back body piece 2 and the second back body piece 3 respectively. The two ends of the strap 11 are in a separated state to facilitate manual tightening of the isolation gown.

[0065] It should be noted that the installation position of the strap 11 is not limited. The strap 11 can be installed on the front piece 1 of the garment according to actual use needs.
