Description

[Technical Field]

[0001] This invention relates to the field of garment manufacturing technology, and in particular to a garment manufacturing method and connection structure based on ultrasonic cutting, as well as clothes and trousers. [Background Technology]

[0002] Clothing refers to various styles of coverings made of fabrics such as cotton, silk, velvet, chemical fibers, polyester, linen, etc., used by humans or through humans to cover the body, keep warm, and decorate themselves. Current clothing manufacturing primarily uses sewing, where garment pieces are cut, overlapped, and sewn together using a sewing machine. After unfolding, the edges are bound to create the finished garment. This process requires significant initial investment in sewing machines and training for workers, resulting in substantial upfront costs in manpower and resources. Furthermore, machine-sewn garments often have seam seams that can rub against the body, affecting comfort. [Summary of the Invention]

[0003] The purpose of this invention is to provide a garment manufacturing method and connection structure based on ultrasonic bonding, as well as clothes and pants. By using ultrasonic bonding technology and the reinforcement effect of reinforcing strips, there is no need to use a sewing machine for sewing, which reduces the initial investment of manpower and material costs. Furthermore, by using ultrasonic bonding and attaching reinforcing strips, no sewn bone structure is formed at the connection position, which avoids rubbing against the body when wearing the garment and improves the comfort of wearing it.

[0004] This application is achieved through the following technical solution: a garment manufacturing method based on ultrasonic cutting, the garment manufacturing method is as follows:

[0005] The garment manufacturing method is as follows:

[0006] Step S1: Design the pattern and style of the garment to obtain preliminary design drawings;

[0007] Step S2: Based on the preliminary design drawings and the proportions and dimensions of each part of the human body model, draw a 1:1 design drawing, and make a pattern according to the design drawing, breaking it down into multiple garment pieces;

[0008] Step S3: Cut out the corresponding shapes of fabric from multiple pieces of clothing, and draw the corresponding seam lines on each piece of fabric. Grab two pieces of fabric from adjacent parts of the garment in turn, and overlap the two pieces of fabric along the edges where they need to be connected. Use an ultrasonic cutter to cut and splice the two pieces of fabric along the seam lines to form a semi-finished garment.

[0009] Step S4: Unfold the semi-finished garment and attach reinforcing strips at the ultrasonic cutting line inside and at the edges of the garment. After the adhesive has cured, the finished garment is obtained.

[0010] In the above-described garment manufacturing method based on ultrasonic cutting, in step S4, a non-elastic fabric is added at the position where the reinforcing strips intersect and overlap. The elasticity of the non-elastic fabric is less than that of the garment fabric.

[0011] In the above-described ultrasonic-based garment manufacturing method, the material of the elastic fabric in step S4 includes one or more of cotton, nylon, and polyester.

[0012] In the above-described ultrasonic-based garment manufacturing method, the elasticity of the reinforcing strip in step S4 is less than the elasticity of the garment fabric.

[0013] In the above-described ultrasonic-based garment manufacturing method, in step S4, a low-elasticity adhesive layer is sprayed at the overlapping positions of the reinforcing strips.

[0014] In the garment manufacturing method based on ultrasonic cutting as described above, the low-elasticity adhesive layer in step S4 includes AB glue.

[0015] A garment connection structure based on ultrasonic cutting technology includes at least two pieces of fabric and a connection structure for connecting adjacent fabrics. The connection structure includes an ultrasonic cutting connection structure for connecting and fixing adjacent fabrics, and a reinforcement structure covering one side of the connection between adjacent fabrics. Each piece of fabric has a suture line. An ultrasonic cutting blade operates along the suture line to form the ultrasonic cutting connection structure. The reinforcement structure covers the ultrasonic cutting connection structure. Adjacent fabrics are overlapped. The suture lines are respectively located on the opposite side of the two adjacent fabrics. The reinforcement device covers the side where the suture line is located to reinforce the connection between the two adjacent fabrics. The reinforcement structure includes a reinforcement strip and an adhesive layer installed on the side of the reinforcement strip facing the ultrasonic cutting connection structure.

[0016] The garment connection structure based on ultrasonic cutting technology as described above includes at least three pieces of fabric, which are connected by the ultrasonic cutting connection structure. Two reinforcing strips are sequentially bonded to the ultrasonic cutting connection structure, and a spring stop is provided at the overlapping part of the reinforcing strips.

[0017] A garment includes a front body, a back body, two sleeves, a neckline, and a connecting structure as described above. The two sleeves are connected end-to-end by the connecting structure to form a sleeve body. The connecting structure connects the front body, the back body, the two sleeve bodies, and the neckline to form the garment. The connection points of the sleeve bodies, the front body, and the back body form a cross-shaped structure. Two reinforcements are intersecting and overlapping at the cross-shaped structure. A spring-stopping element is disposed between the two reinforcement strips corresponding to the cross-shaped structure.

[0018] A pair of trousers includes a first front panel, a second front panel, a first back panel, a second back panel, a waistband, and a connecting structure as described above. The connecting structure connects the first front panel, the second front panel, the first back panel, the second back panel, and the waistband to form trousers. The first front panel, the second front panel, the first back panel, the second back panel, and the waistband form a "T" shape with each pair of the trousers and the waistband. Two reinforcing strips are intersecting and overlapping at the "T" shapes. A spring stop is disposed between the two reinforcing strips corresponding to the cross structure.

[0019] Compared with the prior art, this application has the following advantages:

[0020] 1. This invention discloses a garment manufacturing method based on ultrasonic cutting. Utilizing ultrasonic cutting technology, when overlapping fabric pieces at adjacent locations of the garment, ultrasonic technology is used for cutting. The ultrasonic vibrator generates vibrations that convert electrical energy into mechanical energy, which is then transferred to a HORN welding head for heat transfer. This heat is then transferred to a rotating cutting wheel to achieve the desired ultrasonic processing effect. Simultaneously, the high temperature at the cutting point causes the two pieces of fabric to join. A reinforcing strip is added at the connection point to further strengthen the connection strength between the adjacent fabric pieces. By utilizing ultrasonic cutting technology and the reinforcing effect of the reinforcing strip, sewing is unnecessary, reducing initial labor and material costs. Furthermore, the ultrasonic joining and the application of the reinforcing strip prevent the formation of a sewn-on bone structure at the connection point, avoiding chafing during wear and improving garment comfort.

[0021] 2. The garment connection structure based on ultrasonic cutting technology of the present invention utilizes ultrasonic cutting technology to overlap the fabric at adjacent positions of the garment. During the cutting process, the high temperature at the cutting position causes the two pieces of fabric to join together. A reinforcing strip is added at the connection position to further strengthen the connection strength of the adjacent fabrics. By utilizing ultrasonic cutting technology and the reinforcing effect of the reinforcing strip, there is no need to use a sewing machine for sewing, which reduces the initial investment in manpower and material costs. Furthermore, through ultrasonic joining and the application of reinforcing strips, no sewn bone structure is formed at the connection position, avoiding rubbing against the body during wear and improving the comfort of wearing the garment.

Detailed Implementation Methods

[0032] To make the technical problems, technical solutions, and beneficial effects solved by this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0033] like Figure 1 As shown in Figure 9, this application proposes a garment manufacturing method based on ultrasonic cutting, which is as follows:

[0034] Step S1: Design the pattern and style of the garment to obtain preliminary design drawings;

[0035] Step S2: Based on the preliminary design drawings and the proportions and dimensions of each part of the human body model, draw a 1:1 design drawing, and make a pattern according to the design drawing, breaking it down into multiple garment pieces;

[0036] Step S3: Cut out the corresponding shapes of fabric from multiple pieces of clothing, and draw the corresponding seam lines on each piece of fabric. Grab two pieces of fabric from adjacent parts of the garment in turn, and overlap the two pieces of fabric along the edges where they need to be connected. Use an ultrasonic cutter to cut and splice the two pieces of fabric along the seam lines to form a semi-finished garment.

[0037] Step S4: Unfold the semi-finished garment and attach reinforcing strips at the ultrasonic cutting line inside and at the edges of the garment. After the adhesive has cured, the finished garment is obtained.

[0038] Current garment sewing methods primarily utilize sewing machines. This involves cutting garment pieces, overlapping adjacent pieces, and then sewing them together. This method requires significant investment in equipment and worker training, resulting in high initial costs. Furthermore, the resulting garments have a seam structure that can cause discomfort due to contact and friction with the wearer. In contrast, ultrasonic cutting technology, by overlapping adjacent pieces and cutting them using ultrasonic waves, converts electrical energy into mechanical energy through vibration. This energy is then processed by HORN welding. The ultrasonic cutting head transfers heat, which is then squeezed by the rotating blades to achieve the desired ultrasonic processing effect. During the cutting process, the high temperature at the cutting point causes the two pieces of fabric to join together. However, this joining method is not strong enough, so a reinforcing strip is added at the joining point to further strengthen the connection between the adjacent fabrics. By using ultrasonic cutting technology and the reinforcing effect of the reinforcing strip, there is no need to use a sewing machine, reducing the initial investment in manpower and material costs. Furthermore, by using ultrasonic joining and attaching the reinforcing strip, no seam bone structure is formed at the joining point, preventing chafing against the body during wear and improving the comfort of wearing the garment.

[0039] In step S4, a non-elastic fabric is added at the intersection of the reinforcing strips. The elasticity of the non-elastic fabric is less than that of the garment fabric. The non-elastic fabric in step S4 does not contain spandex. The non-elastic fabric in step S4 includes one or more of cotton, nylon, and polyester. In step S4, a low-elasticity adhesive layer is sprayed at the intersection of the reinforcing strips. The low-elasticity adhesive layer in step S4 includes AB glue. By setting reinforcing strips and non-elastic components with poor elasticity at the connection points of adjacent fabrics, when the garment is stretched and deformed, the deformation tendency at the connection points is reduced due to the pulling effect of the reinforcing strips and non-elastic components, thus preventing tensile cracking at the ultrasonically cut points and affecting the service life of the garment.

[0040] A garment connection structure based on ultrasonic cutting technology includes at least two pieces of fabric 1 and a connection structure 2 for connecting adjacent pieces of fabric 1. The connection structure 2 includes an ultrasonic cutting connection structure 21 for connecting and fixing adjacent pieces of fabric 1, and a reinforcing structure 22 covering one side of the connection point between adjacent pieces of fabric 1. Each piece of fabric 1 has a stitch 11. An ultrasonic cutting blade operates along the stitch 11 to form the ultrasonic cutting connection structure 21. The reinforcing structure 22 covers the ultrasonic cutting connection structure 21 to connect adjacent pieces of fabric 1. Using ultrasonic cutting technology, when adjacent pieces of fabric overlap, ultrasonic cutting is performed, and the ultrasonic waves... The moving part vibrates, converting electrical energy into mechanical energy. This heat is transferred through the HORN welding head and then squeezed by the rotating cutting wheel, achieving the desired effect of ultrasonic processing. During cutting, the high temperature at the cutting point causes two pieces of fabric to join together. However, this joining method is not strong enough, so a reinforcing strip is added at the joining point to further strengthen the connection between the adjacent fabrics. By using ultrasonic cutting technology and the reinforcing effect of the reinforcing strip, there is no need to use a sewing machine, reducing the initial investment in manpower and material costs. Furthermore, by using ultrasonic joining and attaching the reinforcing strip, no seam bone structure is formed at the joining point, preventing chafing against the body during wear and improving the comfort of wearing the garment.

[0041] The adjacent fabrics 1 are overlapped, and the stitching lines 11 are respectively set on the opposite side of the two adjacent fabrics 1. The reinforcing device 22 covers the side where the stitching lines 11 are located to reinforce the connection between the two adjacent fabrics 1. Under the cutting of the ultrasonic cutter, since the fabric 1 has a certain thickness, the adhesion on the side where the adjacent fabrics 1 are close together is relatively good. After unfolding, the side where the two fabrics 1 are far apart cannot be completely bonded. The reinforcing device 22 is set on this side, which can further fix the connection between the two fabrics 1 and isolate the ultrasonic cutting connection structure 21 from the outside world to avoid discomfort when wearing.

[0042] The reinforcing structure 22 includes a reinforcing strip 23 and an adhesive layer 24 installed on the side of the reinforcing strip 23 facing the ultrasonic cutting connection structure 21. The elasticity of the reinforcing strip 23 is less than that of each piece of fabric 1. The connection and reinforcement are performed by adhesive bonding, which is easier to operate and has a relatively low production cost. By utilizing the low elasticity of the reinforcing strip 23, when the fabric 1 is stretched, the reinforcing strip 23 restricts the deformation of the adhesive position, thereby preventing the ultrasonic cutting connection structure 21 from being stretched and cracking, and improving the wear life.

[0043] It includes at least three pieces of fabric 1, which are connected by the ultrasonic cutting and connecting structure 21. Two reinforcing strips 23 are sequentially bonded to the ultrasonic cutting and connecting structure 21. A bullet-stopping element 25 is provided at the overlapping part of the reinforcing strips 23. The bullet-stopping element 25 includes a bullet-stopping fabric or a bullet-stopping adhesive layer. The elastic-stopping fabric includes one or more of cotton, nylon, and polyester. The elasticity of the elastic-stopping component 25 is less than that of the reinforcing strip 23. At the joint of multiple pieces of fabric 1, there are T-shaped or cross-shaped joints. These joints are subject to multi-angle tension and are prone to cracking. By adding the elastic-stopping component 25, the bottom reinforcing strip 23 restricts the tension in the first direction, while the top reinforcing strip 23 restricts the tension in directions intersecting or perpendicular to the first direction. The elastic-stopping component 25 located between two reinforcing strips 23 mainly restricts the tensile deformation of the reinforcing components 23 at the joints corresponding to the T-shaped or cross-shaped structures on both sides, enhances the connection strength of the T-shaped or cross-shaped joints, reduces the deformation of the T-shaped or cross-shaped joints, and thus prevents cracks from occurring at the joints.

[0044] A garment includes a front body 31, a back body 32, two sleeve pieces 33, a neckline 34, and the aforementioned connecting structure 2. The two sleeve pieces 33 are connected end-to-end via the connecting structure 2 to form sleeves. The connecting structure 2 connects the front body 31, the back body 32, the two sleeves, and the neckline 34 to form the garment. A cross-shaped structure is formed at the connection points of the sleeves, the front body 31, and the back body 32. Two reinforcing strips 23 are intersecting and overlapping at the cross-shaped structure. A spring-stopping element 25 is positioned between the two reinforcing strips 23 corresponding to the cross-shaped structure. In terms of clothing, the connection points of the T-shaped or cross-shaped structures are mainly located under the armpits. Since the stitching of the sleeve 33 is located on the side of the arm facing the armpit, and the stitching of the front body 31 and the back body 32 is located on the side of the chest facing the armpit, there is a cross-shaped structure under the armpit. This position is easily subjected to the front-back tension of the chest cavity and the longitudinal tension of the arm rotation. Therefore, the elastic stopper 25 is added at this connection position to further reinforce the connection position and limit the deformation of the fabric on it, so as to prevent the ultrasonic cutting connection structure 21 at this position from cracking.

[0045] A pair of trousers includes a first front panel 41, a second front panel 42, a first back panel 43, a second back panel 44, a waistband 45, and a connecting structure 2 as described above. The connecting structure 2 connects the first front panel 41, the second front panel 42, the first back panel 43, the second back panel 44, and the waistband 45 to form trousers. The first front panel 41, the second front panel 42, the first back panel 43, the second back panel 44, and the waistband 45 are connected in pairs. The two reinforcing strips 23 are arranged to overlap at the T-shaped structure, and the anti-elastic member 25 is arranged between the two reinforcing strips 23 corresponding to the cross structure. There is tensile force around the hip bone and longitudinal tension between the waistband 45 and the pants body at the T-shaped structure position. Therefore, the anti-elastic member 25 is added at this connection position to further reinforce the connection position and limit the deformation of the fabric on it so that the ultrasonic cutting connection structure 21 at this position will crack.

[0046] In summary, this application has, but is not limited to, the following beneficial effects:

[0047] This invention discloses a garment manufacturing method based on ultrasonic cutting, which is as follows: Step S1: Design the pattern and style of the garment to obtain preliminary design drawings; Step S2: Based on the preliminary design drawings and the proportions and dimensions of various parts of the human body model, draw a 1:1 design drawing, and make a pattern according to the design drawing, decomposing it into multiple garment pieces; Step S3: Cut out fabric of corresponding shapes from the multiple garment pieces, draw the corresponding seam lines on each piece of fabric, take two pieces of fabric from adjacent parts of the garment in sequence, and overlap the two pieces of fabric along the edge where they need to be connected. Use an ultrasonic cutter to cut and splice the two pieces of fabric along the seam lines to form a semi-finished garment; Step S4: Unfold the semi-finished garment, and attach reinforcing strips at the ultrasonic cutting lines inside and at the edges of the garment. After the adhesive cures, the finished garment is obtained. Current garment sewing methods primarily utilize sewing machines. This involves cutting garment pieces, overlapping adjacent pieces, and then sewing them together. This method requires significant investment in equipment and worker training, resulting in high initial costs. Furthermore, the resulting garments have a seam structure that can cause discomfort due to contact and friction with the wearer. In contrast, ultrasonic cutting technology, by overlapping adjacent pieces and cutting them using ultrasonic waves, converts electrical energy into mechanical energy through vibration. This energy is then processed by HORN welding. The ultrasonic cutting head transfers heat, which is then squeezed by the rotating blades to achieve the desired ultrasonic processing effect. During the cutting process, the high temperature at the cutting point causes the two pieces of fabric to join together. However, this joining method is not strong enough, so a reinforcing strip is added at the joining point to further strengthen the connection between the adjacent fabrics. By using ultrasonic cutting technology and the reinforcing effect of the reinforcing strip, there is no need to use a sewing machine, reducing the initial investment in manpower and material costs. Furthermore, by using ultrasonic joining and attaching the reinforcing strip, no seam bone structure is formed at the joining point, preventing chafing against the body during wear and improving the comfort of wearing the garment.
