A manufacturing process for straight seams on coat pockets

Abstract

This invention discloses a production process for straight seams on outerwear pockets, comprising: Step 1, fabric splicing: sewing together the required fabrics for the outerwear to create spliced ​​fabric; Step 2, opening the pocket: cutting the spliced ​​fabric prepared in the previous step at a certain width at a designated location according to design requirements, forming a slit; Step 3, trimming: trimming the fabric at the seams on both sides of the slit; Step 4, bonding the lining: bonding the lining to the slit on the back of the trimmed fabric, maintaining the widest part of the slit at a designated width; Step 5, pocket sewing: sewing the pocket according to process requirements. This invention's production process for straight seams on outerwear pockets employs a process of opening the pocket first and then bonding the lining, and trimming the fabric at the slit where the pocket is opened to reduce the fabric thickness at this location; and forming a certain width at the slit before sewing to prepare the pocket, resulting in a straight pocket that does not bulge.

Description

Technical Field

[0001] This invention relates to the field of garment manufacturing technology, and in particular to a production process for straight seams in outerwear pockets. Background Technology

[0002] In the manufacturing process of outerwear, especially women's outerwear, the fabric is often sewn together due to the design requirements of the waist area. Pockets are typically located on the sides of the garment, and because the fabric is sewn together, there are seams. When making the pockets, the sewn fabric needs to be opened at a comfortable location to create a slit. Current technology involves making the slit at the desired opening position first. However, this method results in pockets that arch at the seams, making them uneven and affecting product quality. Summary of the Invention

[0003] The purpose of this invention is to provide a production process for straight seams in coat pockets, so that the pockets of the prepared coats do not bulge and are straight.

[0004] To solve the above-mentioned technical problems, the objective of this invention is achieved as follows:

[0005] The present invention relates to a manufacturing process for straight seams on outer pockets, comprising the following steps:

[0006] Step 1: Fabric splicing: Sew together the fabrics needed for the coat to create a spliced ​​fabric.

[0007] Step 2, Opening the Bag: Cut the spliced ​​fabric prepared in the previous step into a certain width at the designated position according to the design requirements to form a slit;

[0008] Step 3: Trimming: Trim the fabric at the seam on both sides of the cut to reduce its thickness;

[0009] Step 4: Attach the interlining: Attach the interlining to the cut on the back of the trimmed fabric, ensuring that the widest part of the cut has the set width.

[0010] Step 5: Pocket sewing: Sew the pockets according to the process requirements.

[0011] Based on the above scheme and as a preferred embodiment of the above scheme: in step four, the lining is a non-woven fabric.

[0012] Based on the above scheme and as a preferred option: in step four, the width of the widest part of the cut is 0.2-0.3cm.

[0013] Based on the above scheme and as a preferred option: in step four, the width of the widest cut is 0.3cm.

[0014] Based on the above scheme and as a preferred option: in step three, trimming the fabric at the seam refers to trimming obliquely from the edge of the fabric towards the end of the seam at the cut.

[0015] The beneficial effects of the present invention are as follows: The production process for straight splicing of outer pockets involved in the present invention adopts a production process of opening the pocket first and then gluing the lining, and trimming the fabric at the cut of the opening to reduce the thickness of the fabric at this point; and forming a certain width at the cut before sewing to prepare the pocket, so that the prepared pocket does not arch and is straight.

[0023] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0024] Example

[0025] Combination Figure 1 , Figure 2 , Figure 3 and Figure 4 This embodiment will be described in detail below. The production process for straight seams on an outerwear pocket, as described in this embodiment, includes the following steps:

[0026] Step 1: Fabric splicing: The fabrics needed for the outer coat are sewn together to create a spliced ​​fabric. In this embodiment, the fabrics used include a first outer coat fabric 1, a second outer coat fabric 2, and a third outer coat fabric. The first outer coat fabric 1 and the second outer coat fabric 2 are sewn together to form a first seam 4 at the connection point. The second outer coat fabric 2 and the third outer coat fabric 3 are sewn together to form a second seam 5 at the connection point.

[0027] Step 2, Opening the bag: Cut the spliced ​​fabric prepared in the previous step into a certain width at the set position according to the design requirements, forming a slit 6.

[0028] Step 3, Trimming: Trim the fabric at the seam on both sides of the cut 6 to reduce the thickness; the trimming refers to trimming diagonally from the edge of the fabric towards the end of the seam at the cut.

[0029] Step 4: Attaching the interlining: Attach the interlining 8 to the cut on the back of the trimmed fabric, ensuring the widest part of the cut has the set width. Because the seam end at the cut has been modified, the thickness of the fabric at the cut after the interlining is applied can be reduced. Before attaching the interlining, push the upper side of the cut 6 upwards to create a certain gap with the lower side of the cut 6, resulting in a cut with a maximum width of 0.2-0.3cm (0.3cm in this embodiment). Attaching the interlining fixes the shape of the cut, ensuring the seam is straight and does not bulge when sewing the pocket.

[0030] Furthermore, the lining is a non-woven fabric, specifically a spunbond non-woven fabric with a weight of 15-20 grams per square meter.

[0031] Step 5: Pocket sewing: Sew the pockets according to the process requirements.

[0032] Comparative Example 1

[0033] The difference between the manufacturing process of the pocket in this comparative example and the embodiment of this invention lies in the following: after the fabric is spliced ​​together, a lining is glued to the back of the spliced ​​fabric at the location where the pocket needs to be opened, and then the pocket is opened to form a notch. The resulting pocket is as follows: Figure 5 As shown.

[0034] Comparative Example 2

[0035] The difference between the pocket manufacturing process described in this comparative example and the embodiment of this invention lies in the fact that, after trimming the ends of the seams on both sides of the cut, the lining is not glued before pocket preparation. The resulting pocket is as follows: Figure 6 As shown.

[0036] Figure 3 and Figure 5They are similar styles, as can be seen. Figure 3 The produced pockets do not bulge and are straight.

[0037] Figure 4 and Figure 6 They are similar styles, as can be seen. Figure 4 The produced pockets do not bulge and are straight.

[0038] The preferred embodiments of the present invention have been described in detail above. It should be understood that those skilled in the art can make numerous modifications and variations based on the concept of the present invention without creative effort. Therefore, all technical solutions that can be obtained by those skilled in the art based on the concept of the present invention through logical analysis, reasoning, or limited experimentation on the basis of existing technology should be within the scope of protection defined by the claims.
