Description

Underwear patch and attaching process thereof Technical Field The invention belongs to the technical field of underwear production, and particularly relates to an underwear patch and a bonding process thereof. Background In the clothing industry, 2 layers of fabric combinations are commonly used for realizing the design requirement of clothing style, and after the hot-melt adhesive film technology is utilized to replace the traditional sewing technology, the fabric and the hot-melt adhesive film are combined and cut into required shapes to obtain adhesive patches (strips), and the adhesive patches (strips) are subjected to hot-melt bonding at the set positions of the clothing pieces, so that the required design effects such as the appearance effect of patterns and colors, the beam-shaped effect of reinforcing the patches at the appointed positions, the functional effect of the clothing pocket patches and the like can be obtained. The functional effects of the patches are required to be positioned and placed, and the operation modes of positioning and placing currently include the following steps of (1) marking lines on the fabric, wherein the operation mode is low in efficiency and complex in processing process of the lines in the later period, (2) positioning by using paper patterns, the operation is complex and low in efficiency, (3) infrared positioning, the error of the positioning mode is large, the long-time operation can influence the vision, and (4) positioning by using a lamp box base perspective, but the positioning mode has poor perspective effects on some dark, black or thick fabrics, so that the positioning effect is also poor. Disclosure of Invention In view of the above, in order to overcome the defects of the prior art, the invention aims to provide an underwear patch and a bonding process thereof, which can effectively solve the problems existing in the prior art of positioning and placing the patch, and can simultaneously perform positioning and patch operation on the front side and the back side of a garment piece. In order to achieve the above purpose, the present invention adopts the following technical scheme: In one aspect, the present invention provides a process for attaching an undergarment patch, comprising the steps of: Cutting out a garment piece, a bowl mouth bonding patch and a bowl circumference bonding patch according to the underwear style; Preparing a positioning rule according to the shapes of the garment piece, the bowl mouth bonding patch and the bowl surrounding bonding patch, and placing the positioning rule on an air suction base of a hot press, wherein a first groove for accommodating the bowl mouth bonding patch and a second groove for accommodating the bowl surrounding bonding patch are formed in the positioning rule, and garment piece contour lines are further formed in the positioning rule; Firstly, placing the bowl mouth adhesive patch in a first groove, and then positioning and placing the garment piece according to the contour line of the garment piece on the positioning insert piece; The air suction base is started again to adsorb the positioning embedded piece and the clothes piece, so that a concave trace is formed at the position of the clothes piece corresponding to the second groove of the positioning embedded piece, wherein the air suction base can adsorb and fix the whole clothes piece placed with the bowl mouth adhesive patch and the bowl circumference adhesive patch on the one hand, and can form a concave on the clothes piece through the mutual matching of the air suction and the positioning embedded piece after the clothes piece is placed so as to position the bowl circumference; according to the concave trace, placing the bowl surrounding adhesive patch at a position of the garment piece, which is far away from the corresponding second groove on one side of the positioning panel; And finally, starting a hot press to perform hot pressing, so that the bowl mouth adhesive patch and the bowl circumference adhesive patch are respectively adhered to the two sides of the garment piece, and the underwear patch is obtained. In the invention, the bowl mouth bonding patch and the bowl circumference bonding patch are respectively positioned on two sides of the clothing piece, when the clothing piece is paved on the positioning panel, the second groove is covered, so that the placement of the bowl circumference bonding patch is inconvenient, at the moment, the clothing piece is tightly sucked on the positioning panel by utilizing the suction force generated by the suction base, thus a concave trace is generated at the position of the clothing piece corresponding to the second groove, the positioning operation of the second groove can be conveniently performed according to the concave trace generated on the clothing piece, the bowl circumference bonding patch can be placed on the clothing piece clearly and intuitively, the misplacement condition can not occur,
