Description

Technical Field

[0001] This invention belongs to the field of garment manufacturing technology and relates to a heat-sealed single garment and a process for smoothing the edge of the double-layered hood on the single garment. Background Technology

[0002] Commonly seen hooded sweatshirts with heat-sealed construction typically have a single-layer hood structure, with only a fabric strip around the inner hood opening. The exposed seams elsewhere lack refinement, requiring a high level of precision in the heat-sealing process. Furthermore, the direct contact of the fabric's reverse side with the face can be uncomfortable. Double-layered hoods better meet user needs. However, applying heat-sealing directly to the bottom of a double-layered hood carries the risk of the heat-sealing strip detaching. Additionally, the double-layered seams at the front center and neckline can negatively impact wearing comfort due to the thickness of the double-layered tape and seams. Summary of the Invention

[0003] The purpose of this invention is to provide a heat-sealed single garment and a process for smoothing the edge of the double-layered hood on the single garment, thereby solving the above-mentioned technical problems.

[0004] A type of heat-sealed garment includes a double-layered hood, a garment body, heat-sealing strips, patchwork strips, and double-sided adhesive.

[0005] The double-layered hat includes a lining and a face, with the lower edge of the face sewn to the neckline of the garment to form a first seam.

[0006] The double-sided adhesive is bonded to the front side of the strip along its length, and the lower edge of the double-sided adhesive is aligned with the lower edge of the strip.

[0007] The patchwork strip is reversed and facing upwards. The upper edge of the patchwork strip is sewn together with the lower edge of the hood lining. The patchwork strip covers the first seam and is bonded and fixed to the garment body with double-sided tape.

[0008] The heat-sealing strip is pressed against the lower edge of the splicing strip;

[0009] The heat-sealed strip, after being pressed, is fixed by a heat press machine.

[0010] Furthermore, the width of the double-sided adhesive is smaller than the width of the splicing strip.

[0011] Furthermore, the bonding joint between the patchwork strip and the garment body is an adhesive structure reinforced by ironing.

[0012] Furthermore, the lower edge of the splice strip is located in the center of the heat-sealing strip.

[0013] A process for smoothing the bottom edge of a double-layered hood on a seam-sealed garment, the garment comprising a body and a double-layered hood, the double-layered hood including a lining and a face, comprising the following steps:

[0014] The bottom edge of the hat is sewn to the neckline of the garment to form the first seam.

[0015] A splicing strip is provided, and double-sided adhesive is adhered to the front side of the splicing strip along its length, with the lower edge of the double-sided adhesive aligned with the lower edge of the splicing strip.

[0016] Place the patchwork strip with the double-sided adhesive on the inside of the cap, face up, and sew the top edge of the patchwork strip to the bottom edge of the cap.

[0017] Turn the sewn patch over so that it covers the first seam, and use the double-sided tape to glue and fix the patch to the garment.

[0018] A heat-sealing strip is provided, and the heat-sealing strip is pressed onto the lower edge of the splice strip by a heat-sealing machine;

[0019] The heat-sealed strip is pressed again using a heat press machine.

[0020] Furthermore, after the strips are glued and fixed to the garment body, the adhesive joints of the double-sided adhesive are reinforced by ironing.

[0021] Furthermore, the width of the double-sided adhesive is smaller than the width of the splicing strip.

[0022] Furthermore, the lower edge of the splice strip is located in the center of the heat-sealing strip.

[0023] Furthermore, the lower seam edge of the strip is laser-treated to make the lower edge of the double-sided adhesive flush with the lower seam edge of the strip.

[0024] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0025] This invention uses a splicing strip to stagger the inner and outer neckline seams, reducing the thickness of the double-layer seam. The positioning of the double-sided adhesive makes the heat sealing operation more convenient and reduces the risk of easy detachment of the adhesive. While ensuring functionality, it also makes the finished garment more in line with the needs of wearing comfort. While ensuring the waterproof function, it reduces the thickness of the neckline and also reduces the need for a heat sealing strip. Attached Figure Description

[0033] The features and performance of the present invention will be further described in detail below with reference to embodiments.

[0034] Example

[0035] Please see Figures 1-2A type of heat-sealed single garment includes a double-layered hood 10, a garment body 11, a heat-sealing strip 12, a patchwork strip 13, and double-sided adhesive 14. The double-layered hood 10 includes a hood lining 101 and a hood top. The lower edge of the hood top is sewn to the neckline of the garment body 11 to form a first seam 15. The first seam 15 faces upward and is ironed flat to facilitate the subsequent bonding of the double-sided adhesive 14.

[0036] Double-sided adhesive 14 is adhered to the front side of the strip 13 along its length. The lower edge of the double-sided adhesive 14 is aligned with the lower edge of the strip 13, or the lower edge of the double-sided adhesive 14 is aligned with the lower edge of the strip 13 by laser engraving. Preferably, the lower edge of the double-sided adhesive 14 is aligned with the lower edge of the strip 13 by laser engraving, which is more precise and produces a more aesthetically pleasing edge compared to manual alignment.

[0037] With the reverse side of the patchwork strip 13 facing up, the upper edge of the patchwork strip 13 is sewn together with the lower edge of the hood lining 101. The patchwork strip 13 covers the first seam 15 and is glued and fixed to the garment body 11 with double-sided tape 14.

[0038] The heat-sealing strip 12 is pressed onto the lower edge of the strip 13. Specifically, the heat-sealing strip 12 is pressed onto the lower edge of the strip 13 using a heat-sealing machine. The heat-sealing machine has a reference temperature of 460℃, a speed of 10 m / min, a wheel pressure of 0.3 MPa, and an air nozzle pressure of 0.035 MPa. Preferably, the lower edge of the strip 13 is located in the center of the heat-sealing strip 12. This ensures that the heat-sealing strip 12 has an equal-width adhesive layer above and below the edge of the strip 13, which can evenly distribute the tensile stress generated during wear and form a symmetrical waterproof barrier, ensuring good sealing performance even after repeated washing and stretching.

[0039] After pressing, the heat-sealing strip 12 is fixed by applying additional pressure with a heat press machine. The reference temperature of the heat press machine is 150℃, the pressure is 3.5KG, and the time is 35min for hot pressing and 2s / min for cold pressing.

[0040] In another embodiment, the width of the double-sided adhesive 14 is smaller than the width of the strip 13, so that the upper part of the strip 13 is not covered by the double-sided adhesive 14, and the seam between the strip 13 and the lining 101 is smooth and without adhesive residue.

[0041] In another embodiment, the bonding joint between the patch strip 13 and the garment body 11 is an ironed and reinforced bonding structure. Specifically, the double-sided adhesive 14 is heated at the bonding joint between itself and the garment body 11 using an iron. The ironed double-sided adhesive 14 increases the bonding strength, further improves the stability, and significantly enhances the water resistance.

[0042] A process for smoothing the bottom edge of a double-layered hood 10 on a seam-sealed garment, the seam-sealed garment having a body 11 and a double-layered hood 10, the double-layered hood 10 including a hood lining 101 and a hood outer layer, comprising the following steps:

[0043] The bottom edge of the hat is sewn to the neckline of the garment body 11 to form the first seam 15. The first seam 15 is facing upwards and is ironed flat to facilitate subsequent operations.

[0044] A strip 13 is provided, and double-sided tape 14 is adhered to the front side of the strip 13 along its length, so that the lower edge of the double-sided tape 14 is aligned with the lower edge of the strip 13. Preferably, the lower seam edge of the strip 13 is laser-treated so that the lower edge of the double-sided tape 14 is flush with the lower seam edge of the strip 13. The laser treatment makes the lower seam edge of the strip 13 smooth and neat, and precisely aligned with the double-sided tape 14, avoiding the error of manual alignment and improving positioning accuracy and operation efficiency.

[0045] Place the patch strip 13 with double-sided tape 14 facing up on the lining 101, and sew the top edge of the patch strip 13 to the bottom edge of the lining 101.

[0046] Turn the sewn patch 13 over so that it covers the first seam 15, and use double-sided tape 14 to glue and fix the patch 13 to the garment body 11.

[0047] A heat sealing strip 12 is provided, and the heat sealing strip 12 is pressed onto the lower edge of the splice strip 13 by a heat sealing machine.

[0048] The heat-sealed strip 12 is pressed again using a heat press machine.

[0049] In another embodiment, after the patch 13 is glued and fixed to the garment body 11, the adhesive joint of the double-sided adhesive 14 is reinforced by ironing. During the ironing process, it should be ensured that the iron covers the entire adhesive area and moves evenly to avoid local overheating or under-pressure. Ironing reinforcement improves the adhesion between the patch 13 and the garment body 11, prevents the patch 13 from shifting in subsequent processes, and improves production efficiency and yield.

[0050] In another embodiment, the width of the double-sided adhesive 14 is smaller than the width of the strip 13. The upper part of the strip 13 is free of double-sided adhesive 14, which facilitates the stitching operation, making the stitching process smooth and efficient, and the stitches neat. The adhesive-free design of the upper part of the strip 13, combined with the ironed and reinforced adhesive structure of the lower part of the strip 13, makes the functions of both ends of the strip 13 clear - the upper part is easy to sew, and the lower part is firmly fixed. The overall structure is reasonable and the process is simple.

[0051] In another embodiment, the lower edge of the splice strip 13 is located in the center of the heat-sealing strip 12. The centering of the lower edge of the splice strip 13 provides a clear alignment reference for the heat sealing machine, making the operation simple, ensuring good quality consistency, and avoiding defective products caused by misalignment.

[0052] The above description is merely a preferred embodiment of the present invention and is not intended to limit the scope of protection of the present invention. Any modifications, equivalent substitutions, and improvements made by those skilled in the art within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
