[0002] On some garments, the zipper placket is required to be rainproof. Generally speaking, fabrics with a higher waterproof grade and waterproof zippers are used to make garments. However, when fabrics with a slightly lower waterproof grade and ordinary zippers are used, moisture can easily enter along the sewing threads and needle holes, causing the rainproof function to fail. Summary of the invention

[0003] In response to the above technical requirements, the present invention provides a rainproof zipper placket structure. The present invention also provides a method for preparing the rainproof zipper placket structure, aiming to improve the problem of rain seepage of a placket composed of low waterproof grade fabrics and non-waterproof zippers.

[0009] Another technical solution of the present invention is as follows: A method for preparing a rainproof zipper placket structure, comprising the steps of:

[0010] Sewing the first fabric layer and the first side fabric of the bottom tube to the front and back surfaces of the first side code tape of the zipper respectively;

[0011] Rolling a first laminated layer on a side of the first fabric layer facing away from the zipper so that the first laminated layer covers the stitching holes of the first fabric layer and the first side code tape of the zipper, and covers the stitching holes of the first fabric layer, the first side code tape, and the first side fabric;

[0012] The second fabric layer of the bottom tube is overlapped with the first fabric layer, the first side code tape, and the first side fabric to sew the bottom tube closed, so that the sewing line of the first side fabric, the first side code tape of the zipper, the bottom tube, and the first side lining fabric passes through the first glue layer;

[0013] Sewing a first side lining on a side of the second fabric layer of the bottom tube facing away from the first fabric layer;

[0014] The second side fabric and the second side lining fabric are respectively sewn to the front and back surfaces of the second side code tape of the zipper.

[0015] Furthermore, after the second side fabric and the second side lining fabric are respectively sewn to the front and back surfaces of the second side code tape of the zipper, the method includes the following steps: unfolding the first side lining fabric and the first side fabric to both sides respectively and rolling a second glue layer on the sewing positions of the inner surfaces of the first side lining fabric and the first side fabric, so that the second glue layer covers the first side fabric, the first side code tape of the zipper, the bottom tube and the sewing thread eyes of the first side lining fabric.

[0032] The present invention will be further described below in conjunction with the embodiments, but are not intended to limit the present invention.

[0033] Please refer to the accompanying drawings (each of which is used to show the positional relationship of each layer, so each layer will be drawn with a certain thickness, and the illustration will produce an enlarged height difference between each layer due to the thickness), the method for preparing the rainproof zipper placket structure of the embodiment of the present invention includes the following steps:

[0034] Step 1: unfold the bottom tube of two layers of fabric, the first fabric layer 1 and the second fabric layer 2, wherein one side of the first fabric layer 1 and the second fabric layer 2 is already sewn and the other side is openable. Sew the front side of the first fabric layer 1 (the side that will eventually present the appearance of each fabric is defined as the front side, and the other side is defined as the back side) opposite to the back side of the first side code tape 3 of the zipper, as shown in FIG. Figure 1 shown.

[0035] Step 2: Sew the front of the first side fabric 4 opposite to the front of the first side code tape 3 of the zipper. The sewing penetrates the first side fabric 4, the first side code tape 3 of the zipper and the first fabric layer 1. The seams A sewn in steps 1 and 2 are close to or overlap each other. Figure 2 shown.

[0036] Step 3: Roll the first adhesive layer 5 on the side of the first fabric layer 1 facing away from the zipper, i.e., the back side of the first fabric layer 1. The first adhesive layer 5 covers the stitches A sewn in steps 1 and 2, i.e., covers the stitches between the first fabric layer 1 and the first side code tape 3 of the zipper, and covers the stitches between the first fabric layer 1, the first side code tape 3, and the first side fabric 4. The first adhesive layer 5 should cover the edge of the sewing side of the first fabric layer 1, such as Figure 3 shown.

[0037] Step 4: overlap and sew the second fabric layer 2 of the bottom tube with the first fabric layer 1, the first side code tape 3, and the first side fabric 4 to close the bottom tube. The sewing line B in step 4 is close to the edges of the second fabric layer 2, the first fabric layer 1, the first side code tape 3, and the first side fabric 4, and ensure that the sewing line B passes through the first glue layer 5. Figure 4 shown.

[0038] Step 5: Sew the front side of the first side lining 6 to the front side of the second fabric layer 2 of the bottom tube (the side of the second fabric layer 2 facing away from the first fabric layer 1), and the sewing line C is located between the sewing lines A of steps 1 and 2 and the sewing line B of step 4 and is close to the sewing line A of steps 1 and 2, and is generally 0.1 cm away from the sewing line A of steps 1 and 2. The sewing line C runs through the first side lining 6, the second fabric layer 2, the first fabric layer 1, the first side code tape 3 and the first side fabric 4, as shown in FIG. Figure 5 shown.

[0039] Step 6: Fold the first side lining 6 and press the first side lining 6. The pressing line D passes through the first side lining 6 twice, and then passes through the second fabric layer 2, the first fabric layer 1, the first side code tape 3 and the first side fabric 4 in sequence. Figure 6 shown.

[0040] Step 7: Sew the front of the second side fabric 7 and the front of the second side code tape 8 of the zipper opposite to each other. During the sewing, the sewing line E passes through the second side fabric 7 and the second side code tape 8 of the zipper. Figure 7 shown.

[0041] Step 8: Sew the front of the second side lining 9 and the back of the second side code tape 8 of the zipper opposite to each other. During the sewing, the sewing line F passes through the second side lining 9, the second side code tape 8 of the zipper and the second side fabric 7. The sewing line F in step 8 is closer to the zipper teeth than the sewing line E in step 7. Figure 8 shown.

[0042] Step 9: Fold the second side lining 9 and press the second side lining 9. The pressing line G passes through the second side lining 9 twice, and then passes through the second side code tape 8 and the second side fabric 7 in sequence. Fig. 9 shown.

[0043] Step 10: unfold the first side lining 6 and the first side fabric 4 to both sides respectively, and the first side fabric 4, the first side code tape 3 of the zipper, the first stop formed by the bottom tube and the first side lining 6 are turned toward the first side fabric 4, and then the second glue layer 10 is rolled on the sewing position of the first side lining 6 and the inner surface (i.e., the back side) of the first side fabric 4 and the first stop facing the first side lining 6, so that the second glue layer 10 blocks the stitches formed by the pressing line in step 6, and also blocks the passages between the layers of fabric at the first stop position, such as Fig.10 shown.

[0044] Step 11: unfold the second side lining 9 and the second side fabric 7 to both sides respectively, and the second stop formed by the second side fabric 7, the second side code tape 8 of the zipper and the second side lining 9 is turned toward the second side fabric 7, and then the third glue layer 11 is rolled on the sewing position of the second side lining 9 and the inner surface (i.e., the back side) of the second side fabric 7 and the second side fabric 7 and the side of the second stop facing the second side lining 9. The sewing line needle eye formed by the pressing line in the third blocking step 9 also blocks the channel between the layers of fabric at the second stop position, such as Fig.11 shown.

[0045] Finally, each glue layer is pressed to ensure full adhesion. In this embodiment, since the first side lining 6 and the second side lining 9 are pressed, the stitching needle holes covered by the second glue layer 10 and the third glue layer 11 are the stitching needle holes produced by the pressing lines D and G, and the stitching needle holes produced in step 5 must pass through the first glue layer 5 because the stitching line C is close to the stitching line A in steps 1 and 2, and the first glue layer 5 can block it. The stitching needle hole position produced in step 8 can be blocked by the bottom tube, which can meet the rainproof test requirements.
