Description

Technical Field

[0001] This invention belongs to the field of underwear manufacturing technology, specifically relating to an underwear patch and its bonding process. Background Technology

[0002] In the apparel industry, two or more layers of fabric are often used to achieve the design requirements of clothing styles. After using hot melt adhesive film technology to replace the traditional sewing process, the fabric and hot melt adhesive film are combined and cut into the required shape to obtain "adhesive patches (strips)". The adhesive patches (strips) are then hot melted and bonded to the garment pieces at the designated positions to achieve the desired design effects, such as the appearance of patterns and colors, the binding effect of patches reinforcing specific positions, and the functional role of pocket patches.

[0003] To achieve the functional effects of these patches, they need to be positioned and placed. The following are the current methods for positioning and placing: (1) drawing lines on the fabric to make marks. This method is inefficient and the subsequent processing of the lines is complicated; (2) using paper patterns for positioning. This method is complicated and inefficient; (3) infrared positioning. This method has a large error and long-term operation will affect eyesight; (4) using the lightbox base for perspective positioning. However, this method is not good for the perspective effect of some dark, black or thick fabrics, which makes the positioning effect poor. Summary of the Invention

[0004] In view of this, in order to overcome the shortcomings of the prior art, the purpose of this invention is to provide an underwear patch and its bonding process, which can effectively solve the problems existing in the positioning and placement of patches in the prior art, and can perform positioning and bonding operations on both sides of the garment simultaneously.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: This invention provides a bonding process for an underwear patch, comprising the following steps: Cut the garment pieces, bowl-shaped adhesive patches, and bra band adhesive patches according to the style of the underwear; Pre-prepared positioning inserts are made according to the shapes of the garment pieces, bowl rim adhesive patches, and bowl rim adhesive patches, and the positioning inserts are placed on the suction base of the hot press. The positioning inserts are provided with a first groove for accommodating the bowl rim adhesive patch and a second groove for accommodating the bowl rim adhesive patch, and the positioning inserts are also provided with the outline of the garment pieces. First, place the bowl-shaped adhesive patch into the first groove, and then position and place the garment piece according to the outline of the garment piece on the positioning insert; Then activate the suction base to adsorb the positioning insert and the garment piece, so that a recessed mark is formed on the garment piece at the position of the second groove corresponding to the positioning insert; wherein, the suction base can adsorb and fix the garment piece as a whole after the bowl rim adhesive patch and the bowl rim adhesive patch are placed; on the other hand, after the garment piece is placed, the suction and the positioning insert work together to form a recess on the garment piece, so as to facilitate the positioning of the bowl rim. Based on the indentation marks, place the bowl-shaped adhesive patch on the side of the garment piece away from the positioning insert in the corresponding second groove. Finally, the hot press is started to perform hot pressing, so that the cup opening adhesive patch and the cup side adhesive patch are respectively bonded to both sides of the garment piece to obtain the underwear patch.

[0006] In this invention, since the bowl-shaped adhesive patch and the bowl-shaped adhesive patch are located on opposite sides of the garment piece, the second groove is covered when the garment piece is placed on the positioning panel, making it inconvenient to place the bowl-shaped adhesive patch. At this time, the suction force generated by the suction base is used to firmly adhere the garment piece to the positioning panel, thereby creating a recessed mark on the garment piece corresponding to the second groove. The second groove can be easily positioned based on the recessed mark on the garment piece, making it clear and intuitive to place the bowl-shaped adhesive patch on the garment piece. This avoids misalignment and effectively improves the patching efficiency.

[0007] According to some preferred embodiments of the present invention, the positioning insert includes a positioning body and a backing sheet that fit together, the outline of the garment piece is disposed on the side of the positioning body away from the backing sheet, and the first groove and the second groove both penetrate through the thickness direction of the positioning body.

[0008] According to some preferred embodiments of the present invention, the shape of the first groove is the same as the shape of the bowl rim adhesive patch, the shape of the second groove is the same as the shape of the bowl rim adhesive patch, and the outline of the garment piece coincides with the outline of the garment piece.

[0009] According to some preferred embodiments of the present invention, both the first groove and the second groove are located within the area enclosed by the outline of the garment piece, the position of the first groove on the positioning body corresponds to the rim of the garment piece, and the position of the second groove on the positioning body corresponds to the circumference of the garment piece.

[0010] According to some preferred embodiments of the present invention, one side of the bowl-shaped adhesive patch and one side of the bowl-shaped adhesive patch are provided with hot melt adhesive film, and the bowl-shaped adhesive patch and the bowl-shaped adhesive patch are respectively bonded to both sides of the garment piece by the hot melt adhesive film.

[0011] According to some preferred embodiments of the invention, there is a gap between the outline of the garment piece and the side of the corresponding positioning body.

[0012] According to some preferred embodiments of the present invention, the positioning body is made of sponge, and the backing sheet is made of non-elastic fabric. The non-elastic backing sheet on the positioning insert is provided to ensure that the positioning body does not deform when it is held by the subdividing base and subjected to heat pressing.

[0013] According to some preferred embodiments of the invention, the thickness of the positioning body is 1-3 mm.

[0014] According to some preferred embodiments of the invention, the temperature of the hot press during hot pressing is 140-180°C, and the suction of the suction base is turned off during hot pressing.

[0015] The present invention also provides an underwear patch, which is made by the bonding process described above.

Then, position and place the garment piece 4 according to the garment piece outline 113 on the positioning insert 1, as shown. Figure 3 As shown.

[0027] 4) Restart the suction base to adsorb the positioning insert 1 and the garment piece 4, so that a recessed mark is formed on the garment piece 4 at the position of the second groove 112 corresponding to the positioning insert 1.

[0028] 5) Based on the indentation marks formed in step 4, place the bowl-shaped adhesive patch 3 according to the indentation marks on the corresponding second groove 112 on the side of the garment piece 4 away from the positioning body 11, such as... Figure 4 As shown, the side of the bowl-shaped adhesive patch 3 with the hot melt adhesive film faces downward (closer to the garment piece 4).

[0029] 6) Finally, start the upper hot platen of the hot press to press down the positioning insert 1, garment piece 4, cup-shaped adhesive patch 2, and cup-shaped adhesive patch 3 as a whole. Begin heating at a temperature of 140-180℃, while simultaneously turning off the suction base to melt the hot melt adhesive film, so that the cup-shaped adhesive patch 2 and the cup-shaped adhesive patch 3 are respectively bonded to both sides of the garment piece 4, thus obtaining the underwear patch of this embodiment. After hot pressing is completed, lift the pressure plate to remove the underwear patch.

[0030] The present invention discloses a bonding process for underwear patches, which uses a positioning insert 1 for auxiliary positioning, and combines it with a hot press equipped with a suction base.
