Description

Garments with smooth seams Technical Field

[0001] This invention relates to a garment, specifically, to a garment with smooth seams. Background Technology

[0002] During the garment-making process, multiple pieces of fabric are joined together, especially when using quilting. To prevent the seams from coming undone, the stitches are spaced a certain distance from the fabric edge of the garment piece; this allowance is called the seam allowance. In actual garment manufacturing, although methods such as overlocking, binding, and applying adhesive tape are used to conceal the seam allowance, these methods can still result in issues such as visible seams on the outside of the garment and increased thickness at the joint, which can affect the garment's appearance and wearing comfort.

[0003] Patent document 1 discloses a method for sealing the seam of an unlined women's suit without visible seam allowance on the reverse side. The method mainly involves covering and bonding the seam allowance with polyurethane adhesive strips, thereby completely concealing the seam allowance.

[0004] Patent document 2 discloses a flat, highly waterproof, and highly reliable garment bonding structure in which the edges of two fabrics are folded and then bonded together, the roots of the bonding surfaces are sewn together, and finally the two sides are pressed onto any fabric with adhesive strips, thereby increasing the strength of the fabric joint.

[0008] However, in Patent Document 1 and Patent Document 2, compared with conventional fabrics, the adhesive strips are thicker, feel harder, and have poor flexibility, and may fall off after repeated high-temperature ironing or washing.

[0009] To make the joint area smoother, more aesthetically pleasing, and more comfortable to wear, the present invention employs the following techniques:

[0010] [1] A garment with a smooth joint, wherein the inner side of the garment body piece joint is bonded with a strip of bonding fabric by a dotted adhesive, and the strip of bonding fabric completely covers the joint.

[0011] [2] According to the garment with a smooth joint as described in [1], the long strip of fabric is a webbing with a long side overlock.

[0012] [3] According to the garment with a smooth joint as described in [1], the long strip of fitted fabric is the same as the fabric of the main garment piece.

[0013] [4] According to the garment with a smooth joint as described in [3], the fabric ends of the two opposite long sides of the strip-shaped adhesive fabric are folded toward the main body garment piece.

[0014] [5] According to the garment with a smooth joint as described in [4], the folding distance is 2 to 10 mm.

[0015] [6] The garment with a smooth joint according to any one of [1] to [3], wherein the width of the strip-shaped adhesive fabric is 5 to 22 mm.

[0016] [7] The patch adhesive is a reactive hot melt adhesive in the garment with a smooth joint as described in [1]. Attached Figure Description

Detailed Implementation

[0023] When sewing clothes, a certain distance needs to be left between the thread and the fabric edge to ensure the strength of the stitching. This section from the thread to the fabric edge is generally called the seam allowance. However, a certain width of seam allowance not only affects the appearance of the garment when hanging, but also the friction from the raised seam allowance against the skin when worn close to the skin, affecting comfort. Existing technologies also include joining methods other than sewing, such as ultrasonic bonding or thermal bonding, but the bonding strength at these joints is slightly insufficient.

[0024] This invention provides a garment with a smooth joint, strong connection, and a feel and flexibility similar to the main fabric.

[0025] Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

[0026] Figures 1 and 2 are schematic diagrams illustrating one embodiment of the present invention. In Figure 1, the left garment piece 1 and the right garment piece 2 are sewn together by a flat seam. The resulting seam allowance 3 is split and pressed onto the left garment piece 1 and the right garment piece 2 respectively. Then, a strip of bonding fabric 4 is simultaneously fixed and bonded to the seam allowance 3, the left garment piece 1, and the right garment piece 2 using a dotted adhesive 5, so that the strip of bonding fabric 4 completely covers the seam allowance 3. When processing the seam allowance 3, it is also possible, as shown in Figure 2, to backstitch the seam allowance 3, so that the seam allowance 3 is pressed onto the left garment piece 1 or the right garment piece 2, and then the strip of bonding fabric 4 is simultaneously fixed and bonded to the seam allowance 3, the left garment piece 1, and the right garment piece 2 using a dotted adhesive 5, so that the strip of bonding fabric 4 completely covers the seam allowance 3.

[0027] The seam allowance 3 is typically 3-10mm wide during sewing. When backstitching, the width of the joint is the same as the seam allowance 3; when splitting, the width of the joint is twice the seam allowance 3. The width of the elongated fabric 4 needs to be slightly larger than the joint width, completely covering the joint while ensuring that the left and right garment pieces 1 and 2 are each fixedly connected to the elongated fabric 4 with at least one row of dotted adhesive 5 (i.e., the elongated fabric 4 needs to be at least 1mm wider on each side than the seam allowance). Considering both conditions, the width of the elongated fabric 4 is preferably 5-22mm. It should be noted that when the elongated fabric 4 is laid flat on a horizontal table without wrinkles, the two long sides can be parallel, or they can be curves or folds of the same frequency. The width of the elongated fabric 4 refers to the shortest distance between the two long sides perpendicular to its length.

[0028] The elongated bonding fabric 4 can be made of woven or knitted tape with two long edges overlocked. With the two long edges overlocked, the elongated bonding fabric 4 has no exposed loose threads, avoiding fraying or loose edges during use. However, due to the difference in feel between woven and knitted tapes, woven tapes are generally stiffer and lack elasticity, while knitted tapes are softer and have a certain degree of elasticity. Therefore, knitted tape is preferred as the elongated bonding fabric 4.

[0029] Besides using woven or knitted ribbons as the long strip bonding fabric 4, for the sake of overall garment appearance consistency, the same fabric as the main garment piece can also be used as the long strip bonding fabric 4. It should be noted that "same as the main garment piece fabric" includes being completely identical to the main garment piece fabric, and also includes being similar in color or material. When the long strip bonding fabric 4 is the same as the main garment piece fabric, since the two long sides of the long strip bonding fabric 4 are formed by cutting the fabric, as shown in Figures 1 and 2, the two long sides are exposed, which may lead to frayed edges during subsequent use. To avoid this phenomenon, the present invention provides the bonding method shown in Figure 3. As shown in Figure 3, the fabric ends of the two opposite long sides of the long strip bonding fabric 4 are folded towards the main garment piece side, and then the folded fabric ends are folded 8 and bonded to the joint of the main garment piece inside the garment using dotted adhesive 5. At this time, the fabric ends of the two opposite long sides of the long strip of fabric 4 are hidden between the main garment piece and the long strip of fabric 4, so that there will be no frayed edges or loose edges.

[0030] The folding width of the two opposite long sides of the elongated bonding fabric 4 is preferably 2-11 mm. If the folding width is too small, the folding and bonding operations will be more difficult, and the folded fabric ends may easily unfold again. If the folding width is too large, the overall thickness of the joint will increase, which will also increase the cost of the elongated bonding fabric 4 and the adhesive. Therefore, to facilitate the folding and bonding of the fabric ends and to make the joint relatively flat, the folding width is more preferably 2-5 mm. In actual operation, the folding width of the two opposite long sides of the elongated bonding fabric 4 is kept consistent, preferably 2-11 mm, and more preferably 2-5 mm. Of course, it is not excluded that different folding widths may be set according to special needs.

[0031] It should be noted that the bonding method described in Figures 1 to 3 of this invention is not only applicable to the joints of different garment pieces sewn together, but also to the joints of different fabrics formed by other sewing or non-sewing methods, such as ultrasonic bonding and thermal bonding. The joints of ultrasonic bonding and thermal bonding are relatively flat. The purpose of bonding the long strip of bonding fabric 4 to their joints is mainly to increase the strength of the joint and prevent the joint from cracking.

[0032] Figure 4 shows a schematic diagram of a strip of bonding fabric 4 attached to the joint of different garment pieces formed by ultrasonic bonding or thermal bonding. The strip of bonding fabric 4 is simultaneously fixed to the left garment piece 1 and the right garment piece 2 by dotted adhesive 5 to cover the ultrasonic bonding joint 7. When the strip of bonding fabric 4 is a woven or knitted ribbon, it can be laid flat as shown in Figures 1 and 2; when the strip of bonding fabric 4 is the same as the fabric of the garment piece, it is preferable to fold it first and then attach it as shown in Figure 3.

[0033] As shown in Figure 5, the long strip of bonding fabric is not only suitable for the connection of two or more pieces of fabric, but also for the folded ends of a single piece of fabric, such as the hem and cuffs. Bonding the long strip of bonding fabric to the hem or cuffs strengthens the joint and makes the edges smooth. During bonding, the long strip of bonding fabric 4 is fixed to the left garment piece 1 by dotted adhesive 5 covering the seam 6 and seam allowance 3. When the long strip of bonding fabric 4 is a woven or knitted ribbon, it can be bonded flat as shown in Figures 1 and 2; when the long strip of bonding fabric 4 is the same fabric as the main garment piece, it is preferable to fold it first and then bond it as shown in Figure 3.

[0034] The diameter of the dotted adhesive described in this invention is set between 0.5 and 2 mm. To ensure that the bonded edges do not lift, the distance between the dotted adhesive near the edge and the edge should be within 2 mm, more preferably within 1 mm. The spacing between the centers of the dotted adhesive is preferably 1 to 5 mm, and more preferably 2 to 3 mm to further increase the adhesive strength.

[0035] In this invention, regarding the resin constituting the dotted adhesive, synthetic resins are preferred, and thermoplastic resins are more preferred. Examples include polyethylene, polypropylene, polyvinyl chloride, polystyrene, polyvinyl acetate, polyurethane, polytetrafluoroethylene, polyacrylic acid, polyamide, polyacetal, polycarbonate, polyphenylene ether, polyester, polyphenylene sulfide, polysulfone, polyethersulfone, polyetheretherketone, polyimide, and polyamide-imide.

[0036] It is preferred that the resin constituting the adhesive is a reactive hot melt adhesive. When the resin is a reactive hot melt adhesive, the resin softens or melts and penetrates into the interstices of the adhesive area. After cooling and solidification, it reacts with the surrounding moisture, thereby cross-linking, and forming an adhesive structure with excellent heat resistance, solvent resistance, and washability.

[0037] This invention creates a garment by attaching a long strip of fabric to the joint of the main body piece on the inside of the garment, resulting in a smoother and more aesthetically pleasing joint, stronger connection, and a feel and flexibility similar to the main body fabric, making it more comfortable to wear.

[0038] Example 1

[0039] Prepare two rectangular pieces of clothing fabric, align the ends of the fabric, and sew them together on the reverse side of the fabric, setting the seam allowance to be 3mm.

[0040] A woven tape with an 8mm width and overlocked edges is used as a long strip of bonding fabric 4. Four rows of dot-shaped adhesive 5 are coated on one side of the long strip of bonding fabric 4 in a straight array along its length. The dot-shaped adhesive 5 is a circle with a diameter of 0.8mm. The distance between the center of the outermost dot-shaped adhesive 5 and the edge of the woven tape is within 1mm, and the distance between adjacent dot-shaped adhesive 5 is 3mm (distance between the center points).

[0041] Make a split seam allowance 3 (press the seam allowance to both sides and iron it), then align the side of the long strip of bonding fabric 4 coated with dotted adhesive 5 with the middle position of the seam allowance 3, and use a heating machine to heat the long strip of bonding fabric 4 at 80℃ for 10 seconds, so that the long strip of bonding fabric 4 covers the seam allowance 3, as shown in Figure 1.

[0042] At this point, the garment does not show seam allowances, but because woven tape is used, the joints feel stiff but the shape is smoother, making it suitable for outerwear.

[0043] Example 2

[0044] Replace the woven tape with a knitted tape of the same size, and the rest is the same as in Example 1.

[0045] At this point, the garment has no visible seams, and the joints are soft to the touch, making it suitable for clothing that comes into direct contact with the skin.

[0046] Example 3

[0047] Fold the seam allowance 3 to one side and iron it. The rest is the same as in Example 2, as shown in Figure 2.

[0048] At this point, the garment has no visible seams. With the same width of the bonding fabric, the bonding fabric and the main garment fabric have a wider joint, resulting in a tighter bond.

[0049] Example 4

[0050] When sewing flat, the width of the seam allowance is set to 5mm, and the width of the long strip of fabric 4 is 12mm, the rest is the same as in Example 2.

[0051] At this point, the garment does not show seam allowances, and its appearance is flat and beautiful. However, seam allowance 3 is relatively wide, which increases the amount of fabric used for the garment body and the long strip of bonding fabric 4.

[0052] Example 5

[0053] When sewing flat, the width of the seam allowance is set to 1mm, and the width of the long strip of fabric 4 is 5mm, the rest is the same as in Example 2.

[0054] At this point, the seam allowance is not visible, but a seam allowance that is too narrow is difficult to sew, and there may be gaps in the seam. Although there will be no cracks at the seam after attaching the long strip of bonding fabric 4, there will be openings on the front of the garment where the seam is not sewn, affecting the appearance of the front.

[0055] Example 6

[0056] Prepare a rectangular piece of garment fabric. Fold one end of the fabric inward by 20mm and sew it together with the main fabric of the garment to form the hem of the garment. Attach a 7mm wide patch to the hem. The rest is the same as in Example 1.

[0057] At this point, the inner seam and fabric edge are not exposed, resulting in a smoother and more aesthetically pleasing finish.

[0058] Example 7

[0059] The same fabric as the rectangular garment fabric is selected as the strip bonding fabric 4. The width of the strip bonding fabric 4 is 8mm, and the rest is the same as in Example 1.

[0060] Because the bonded fabric is consistent with the garment, it looks more uniform and aesthetically pleasing. However, the two long edges of the bonded fabric are exposed, which can easily cause frayed edges during wear.

[0061] Example 8

[0062] The width of the strip-shaped bonding fabric 4 is 18mm. First, the two opposite long sides of the strip-shaped bonding fabric 4 are folded 4mm towards the main garment piece and ironed. Then, dotted adhesive 5 is applied. The rest is the same as in Example 7. The shape of the strip-shaped bonding fabric 4 is shown in Figure 3.

[0063] Compared to Example 7, since the long side of the strip-shaped adhesive fabric 4 is folded inward first, the fabric end is not exposed, and no frayed edges will be generated during wear.

[0064] Example 9

[0065] After aligning the ends of the fabric, cut off the excess part by ultrasonic sewing, and then attach a long strip of fabric 4 to the ultrasonic sewing joint, the rest is the same as in Example 1.

[0066] Because of the use of ultrasonic sewing, there are no protrusions at the seam itself, and the strength of the joint is enhanced after the long strip of bonding fabric 4 is pasted on.

[0067] Comparative Example 1

[0068] Replace the woven tape with polyurethane strips, and the rest is the same as in Example 1.

[0069] The polyurethane adhesive strips used have a stiff feel and will leave obvious marks on thinner clothing, affecting wearing comfort.

[0070] Comparative Example 2

[0071] Replace the woven tape with polyurethane strips, and the rest is the same as in Example 9.

[0072] Polyurethane adhesive strips provide sufficient strength, but they have a poor feel and affect wearing comfort.
