Description

Technical Field

[0001] This utility model relates to the field of garment manufacturing technology, and more specifically, to a stand-up collar sewing template with an embedded knitted fabric piece. Background Technology

[0002] Current down jacket collars typically use non-elastic fabric (the same fabric as the body), which provides good overall garment integrity. However, this fabric feels cold to the touch in winter, and since the collar is in direct contact with the neck skin, comfort is reduced, resulting in a poor experience. To address this, researchers changed the inner lining of the collar to a knitted fabric. The elasticity of the knitted fabric improves comfort and reduces the coldness. However, the excessive elasticity of the knitted fabric, coupled with its tendency to deform when sewn to the zipper on the body, leads to frequent stitching and requires subsequent binding, increasing cost and significantly increasing the manufacturing difficulty, also affecting the aesthetics of the finished product. Therefore, researchers have improved the design by replacing only the fabric at the neck area with knitted fabric, creating an inset, patchwork collar. The specific processing steps include:

[0003] (1) Draw vector lines. First, prepare cardboard of various sizes, and then use the cardboard to determine the length and width of the knitted fabric piece to be sewn.

[0004] (2) Draw lines on the inner collar fabric;

[0005] (3) Cut out the corner seam position that is appropriate for the knitted fabric;

[0006] (4) Draw vector lines on the collar fabric to mark the buttonhole positions, zipper positions, and collar zipper eyebrow positions;

[0007] (5) Sew the zipper thread;

[0008] (6) After the stitching is completed, sew a collar collar eyebrow along the edge;

[0009] (7) Turn it over and sew the inner collar and the down-proof pouch together;

[0010] (8) Use a template to fix the vector of the downproof bag and the knitted inner collar.

[0011] The aforementioned processing steps are complex. Furthermore, the knitting direction is vertical, perpendicular to the collar edge, meaning the elastic direction is horizontal. This leads to inconsistent drape and tension on both sides during sewing, and variations in the width of the combined fabric and knitted inlay. Uneven fabric allowance occurs during the sewing of the zipper and zipper flap (i.e., collar flap), especially on collars with a slight curve, resulting in an uneven curve after sewing. The two ends of the collar are prone to size discrepancies, and the inner and outer collar lengths are uneven. Most importantly, the area covering the neck may exhibit a "tight outside, loose inside" or "loose outside, tight inside" situation. If the outside is tight and the inside is loose, it will feel constricting around the neck; if the outside is loose and the inside is tight, the external wrinkles will be unsightly. In addition, the positioning and size of the collar need to be extremely precise; otherwise, the finished product will be aesthetically unappealing, and it may bulge near the neck, causing chafing. All these factors combined mean that even skilled workers can make mistakes, leading to low production efficiency and poor sewing quality. Utility Model Content

[0012] This utility model discloses a stand-up collar sewing template with an embedded knitted fabric piece, which aims to improve the problems of complicated sewing process, poor sewing quality and low production efficiency of existing stand-up collars with embedded knitted fabric pieces.

[0013] The present invention adopts the following solution:

[0014] A stand-up collar sewing template with an embedded knitted fabric piece includes an interconnected and closable collar base plate and an inner collar base plate. The collar base plate has a middle layer plate and a collar top plate. The middle layer plate is located between the collar base plate and the collar top plate, with one side for pressing together the collar padding and collar fabric piece on the collar base plate, and the other side having a zipper stop strip and a zipper header stop strip. The collar top plate is closable with the middle layer plate for pressing together the zipper and zipper header. The inner collar base plate has an inner collar top plate, which, together with the inner collar base plate, presses together the collar base plate. The collar consists of a layer of downproof fabric and a knitted fabric piece. The outer collar base plate has a zipper groove and a first joining groove. The zipper groove is used to sew the bottom of the outer collar to allow the collar pad, outer collar piece, zipper, and zipper vent to be sewn together. The inner collar base plate has an inner collar sewing groove and a second joining groove corresponding to the first joining groove. The inner collar sewing groove is used to sew the bottom of the inner collar to allow the knitted fabric piece to be sewn to the two layers of downproof fabric. When the outer collar base plate and the inner collar base plate are closed, the first joining groove and the second joining groove coincide. Sewing along the trajectory of the joining groove allows the inner collar to be joined with the outer collar.

[0015] As a further improvement, the inner collar top plate includes an upper top plate and a lower top plate. The upper top plate is connected to the inner collar bottom plate and is located close to the outer collar bottom plate. The lower top plate is connected to the side of the inner collar bottom plate away from the outer collar bottom plate. When the upper top plate and the lower top plate cover the inner collar bottom plate, the outer edge of the upper top plate is engaged and limited by the outer edge of the lower top plate.

[0016] As a further improvement, one end of the middle layer plate is connected to the bottom plate of the collar, and the other end is connected to the top plate of the collar, in order to limit the slippage of the zipper.

[0017] As a further improvement, the outer collar base plate and the inner collar base plate have the same shape, and the middle layer plate, outer collar top plate, upper top plate and lower top plate are all formed by dividing the base plates of the same shape.

[0018] As a further improvement, the outer collar bottom plate and the inner collar bottom plate, the outer collar bottom plate and the middle layer plate, the middle layer plate and the outer collar top plate, the inner collar bottom plate and the upper top plate, and the inner collar bottom plate and the lower top plate are all connected by adhesive tape.

[0019] As a further improvement, both the inner collar base plate and the outer collar base plate are equipped with positioning pins.

[0020] As a further improvement, a marking groove for marking buttonholes and slits is provided along the outer periphery of the inner collar sewing groove and the zipper groove.

[0021] As a further improvement, the outer collar base plate is provided with a first anti-slip strip along the outer periphery of the zipper groove and the first splicing groove, and the inner collar base plate is provided with a second anti-slip strip along the outer periphery of the inner collar sewing groove and the second splicing groove.

[0022] As a further improvement, the zipper limiting strip and the zipper header limiting strip are both similar in shape to the zipper groove and are configured in different colors.

[0023] As a further improvement, a plurality of padding strips perpendicular to the zipper groove are provided at intervals along the zipper limiting strip, and pressure strips are provided on the top plate of the collar that are staggered with the padding strips.

[0024] By adopting the above technical solution, the present invention can achieve the following technical effects:

[0025] 1. First, the zipper and zipper header are sewn onto the collar using the zipper groove. The width and direction of the zipper groove are determined to ensure the smoothness and ease of sewing the zipper and zipper header, resulting in a flat seam. Zipper and zipper header guide strips further ensure accurate placement and sewing positions of the zipper and zipper header. Second, the inner collar seam groove allows the bottom of the knitted fabric piece to be sewn to the two layers of down-proof fabric. The seam groove trajectory is defined, and the inner collar top plate is pressed together during the stitching process to ensure a consistent ease of sewing, preventing deformation of the knitted fabric. After sewing, the two layers of down-proof fabric form a down-filling pocket for later down filling. Finally, the collar bottom plate and inner collar bottom plate are overlapped so that the collar piece and knitted fabric piece are aligned, with the first and second joining grooves coinciding. A pattern line is sewn along the joining groove trajectory, thus achieving the top joining of the collar and inner collar. This application eliminates the need for multiple drawing and cutting steps, enabling the stitching of a patchwork stand-up collar. It involves fewer processing steps and is simple to operate. Operators only need to place the fabric in sequence and then sew along the stitching groove. It requires less technical skill from operators, which can improve processing efficiency and the consistency of sewing quality, thereby enhancing the market competitiveness of the product.

[0026] 2. When the top plate is closed, the outer edge of the top plate is used to limit it, which can prevent the top plate from sliding outward, ensure the overlap between the second through groove and the first splicing groove, avoid misalignment between the second through groove and the first splicing groove, and ensure the accurate stitching position of the inner collar and the outer collar.

[0027] 3. Both the outer collar base plate and the inner collar base plate are identical in shape, differing only in their placement. All other plates are formed by dividing the same base plate, ensuring consistent groove shapes and facilitating template replacement and maintenance. This also simplifies production molds and processes, reducing template manufacturing costs. Preferably, the base plate is made of PVC material with a thickness not exceeding 2mm, resulting in low cost. The grooves or holes on the base plate are laser-cut to ensure accurate curvature, and the transparent material allows operators to easily observe the fabric placement sequence.

[0028] 4. Marking grooves are provided along the outer perimeter of the inner neckline seam groove and zipper groove for marking buttonhole positions and pointed points. After sewing the pattern line along the zipper groove, the width endpoint, buttonhole position, and pointed point can be marked on the outer collar piece. Similarly, after sewing the pattern line along the inner neckline seam groove, the width endpoint, buttonhole position, and pointed point can be marked on the knitted fabric piece. This facilitates positioning when sewing the collar to the body; the operator can simply draw lines along the marking grooves, ensuring accurate positioning and quick line drawing.

[0029] 5. When placing the zipper, position the zipper teeth along the zipper groove. Since the zipper teeth have a certain thickness, the padding strips can provide some support to the zipper fabric. The staggered placement of the padding strips and pressure strips can press the zipper together and also provide some slack for the zipper seam, ensuring a smooth seam between the zipper and the zipper header.

[0046] Example

[0047] Combination Figures 1 to 9 This embodiment provides a stand-up collar sewing template with an embedded knitted fabric piece, including an outer collar base plate 1 and an inner collar base plate 2 that are interconnected and can be opened and closed relative to each other. Specifically, the outer collar base plate 1 is provided with a middle layer plate 3 and an outer collar top plate 4. The middle layer plate 3 is located between the outer collar base plate 1 and the outer collar top plate 4. One side of the middle layer plate 3 is used to press the collar padding and collar fabric piece on the outer collar base plate 1, and the other side is provided with a zipper limiting strip 31 and a zipper header limiting strip 32. The outer collar top plate 4 and the middle layer plate 3 are openable and closable to press the zipper and zipper header together. The inner collar base plate 2 is provided with an inner collar top plate. The inner collar top plate and the inner collar base plate 2 are used to... Two layers of downproof fabric and knitted fabric pieces are pressed together; the outer collar base plate 1 is provided with a zipper groove 11 and a first splicing groove 12. The zipper groove 11 is used to sew the bottom of the outer collar so that the collar pad, outer collar piece, zipper and zipper eyelet are sewn together. The inner collar base plate 2 is provided with an inner collar sewing groove 21 and a second splicing groove 22 corresponding to the first splicing groove 12. The inner collar sewing groove 21 is used to sew the bottom of the inner collar so that the knitted fabric piece is sewn to the two layers of downproof fabric. When the outer collar base plate 1 and the inner collar base plate 2 are covered, the first splicing groove 12 and the second splicing groove 22 coincide. Sewing along the trajectory of the splicing groove can make the inner collar and the outer collar spliced ​​together.

[0048] In this embodiment, firstly, the zipper and zipper header are sewn onto the collar piece using the zipper groove 11. The width and extension direction of the zipper groove 11 are determined to ensure the direction and amount of fabric during the sewing process of the zipper and zipper header, ensuring a smooth seam between the zipper and the collar. The zipper limiting strip 31 and the zipper header limiting strip 32 further ensure the accuracy of the placement and sewing position of the zipper and zipper header. Secondly, the bottom of the knitted fabric piece is sewn to the two layers of downproof fabric using the inner collar sewing groove 21. The sewing groove trajectory is determined, and the inner collar top plate presses the stitches together during the sewing process, ensuring a consistent amount of fabric fabric and preventing deformation during sewing. After sewing, the two layers of downproof fabric form a down-filling pouch for later down filling. Finally, the outer collar base plate 1 and the inner collar base plate 2 are overlapped so that the outer collar piece and the knitted fabric piece are facing each other, and the first joining groove 12 and the second joining groove 22 coincide. The pattern line is sewn along the joining groove trajectory, thereby achieving the top joining of the outer collar and the inner collar. This embodiment can achieve the sewing of the spliced ​​stand collar without multiple drawing and cutting. The processing steps are few and the operation is simple. The operator only needs to put the fabric in one by one and then sew along the stitching groove. The technical requirements for the operator are low, which can improve processing efficiency and the consistency of sewing quality, thereby enhancing the market competitiveness of the product.

[0049] In a preferred embodiment, the inner collar top plate includes an upper top plate 5 and a lower top plate 6. The upper top plate 5 is connected to the inner collar bottom plate 2 and is disposed close to the outer collar bottom plate 1. The lower top plate 6 is connected to the side of the inner collar bottom plate 2 away from the outer collar bottom plate 1. When the upper top plate 5 and the lower top plate 6 cover the inner collar bottom plate 2, the outer edge of the upper top plate 5 is engaged and limited by the outer edge of the lower top plate 6. For example, the upper top plate 5 is provided with a second through groove 51 corresponding to the second splicing groove 22, and the lower top plate 6 is provided with an inner collar through groove 61 corresponding to the inner collar sewing groove 21. The outer edge of the upper top plate 5 is set to be concave, and the outer edge of the lower top plate 6 is set to be convex. Since the lower top plate 6 is connected to the other side of the inner collar bottom plate 2, when the outer collar bottom plate 1 and the inner collar bottom plate 2 are covered, the upper top plate 5 can be prevented from sliding outward, ensuring the overlap of the second through groove 51 and the first splicing groove 12, avoiding misalignment of the second through groove 51 and the first splicing groove 12, and ensuring the accurate stitching position of the inner collar and the outer collar.

[0050] Based on the above embodiments, in an optional embodiment of this utility model, the outer collar base plate 1 and the inner collar base plate 2 have the same shape, and the middle layer plate 3, the outer collar top plate 4, the upper top plate 5, and the lower top plate 6 are all formed by dividing base plates of the same shape. It is easy to understand that the outer collar base plate 1 and the inner collar base plate 2 are base plates of the same shape, differing only in their placement. All other plates are formed by dividing the same base plate, thus ensuring consistent groove shapes and facilitating template replacement and maintenance. Simultaneously, it can simplify production molds or production process steps, thereby reducing template manufacturing costs. Preferably, the base plate is made of PVC material with a thickness of no more than 2mm, resulting in low cost. The grooves or holes on the base plate are formed by laser cutting to ensure accurate forming curvature, and the transparent material allows operators to easily observe the order of fabric placement. The outer collar base plate 1 is connected to the inner collar base plate 2, the outer collar base plate 1 to the middle layer plate 3, the middle layer plate 3 to the outer collar top plate 4, the inner collar base plate 2 to the upper top plate 5, and the inner collar base plate 2 to the lower top plate 6 via adhesive tape. This design allows the connection point between the two panels to be folded, while ensuring sufficient adhesion during the pressing process to achieve the desired fabric bonding effect. Furthermore, the adhesive tape connection is easy to replace, has high fatigue resistance, and is low in cost. All panels are connected, preventing panel loss or damage. It's worth noting that one end of the middle layer panel 3 connects to the collar bottom panel 1, and the other end connects to the collar top panel 4, which restricts the direction of the zipper and prevents the zipper from slipping in the same direction as the collar fabric piece.

[0051] Furthermore, both the inner collar base plate 2 and the outer collar base plate 1 are equipped with positioning pins 13 to facilitate positioning when the operator places the fabric, preventing the fabric from shifting during placement. In a preferred embodiment, the positioning pins 13 are arranged along the protrusions of the base plates, and the positioning pins 13 on the inner collar base plate 2 and the outer collar base plate 1 are staggered, which can form a limiting effect during the closing process, so as to further ensure that the first splicing groove 12 and the second splicing groove 22 coincide when the cover is closed.

[0052] In another embodiment, a marking groove 14 for marking buttonhole positions and pointed points is provided along the outer periphery of the inner collar seam groove 21 and the zipper groove 11. Preferably, the marking groove 14 extends from the bottom plate through the top collar plate 4 and the lower top plate 6. After sewing the pattern line along the zipper groove 11, the width endpoint, buttonhole position, and pointed point can be marked on the collar fabric piece. Similarly, after sewing the pattern line along the inner collar seam groove 21, the width endpoint, buttonhole position, and pointed point can be marked on the knitted fabric piece. This facilitates positioning when sewing the collar and body together; the operator can simply draw lines along the marking groove 14, ensuring accurate positioning and quick line drawing.

[0053] In other embodiments, the outer collar base plate 1 is provided with a first anti-slip strip 15 along the outer periphery of the zipper groove 11 and the first splicing groove 12, and the inner collar base plate 2 is provided with a second anti-slip strip 23 along the outer periphery of the inner collar sewing groove 21 and the second splicing groove 22. The first anti-slip strip 15 and the second anti-slip strip 23 can be frosted cloth, which increases the friction between the fabric and the base plate to prevent the fabric from slipping. By placing the anti-slip strips on the base plate so that they only contact the inner surface of the fabric, the exposed surface of the fabric can be prevented from being abraded, thus ensuring the integrity of the exposed surface.

[0054] Based on the above embodiments, in an optional embodiment of this utility model, the zipper limiting strip 31 and the zipper header limiting strip 32 are both similar in shape to the zipper groove 11 and are configured in different colors. For example, the zipper limiting strip 31 is white and the zipper header limiting strip 32 is yellow, making it easy for operators to identify. The two limiting strips are arranged side by side, and the height of the zipper limiting strip 31 can be set lower than the height of the zipper header limiting strip 32 to facilitate the operator's placement of the zipper and zipper header. Furthermore, multiple raising strips 33 perpendicular to the zipper groove 11 are arranged at intervals along the zipper limiting strip 31, and pressure strips 42 are arranged on the top plate 4 of the collar, staggered with the raising strips 33. When placing the zipper, the zipper teeth are placed along the zipper groove 11. Since the zipper teeth have a certain thickness, the setting of the raising strips 33 can provide a certain support for the zipper fabric. For example, the zipper limiting strip 31, zipper eyebrow limiting strip 32, padding strip 33 and pressure strip 42 are all EVA adhesive strips, which are pasted on the board surface. The padding strip 33 and pressure strip 42, which are staggered, can press the zipper together and also provide a certain amount of looseness for the zipper to be sewn, so as to ensure that the zipper and zipper eyebrow are sewn together smoothly.

[0055] The usage method of this embodiment includes the following steps:

[0056] Step 1: Refer to Figure 1 Open the sewing template so that the outer collar base plate 1 and the inner collar base plate 2 are laid flat on the workbench;

[0057] Step Two: Refer to Figure 3 Turn one side of the collar base plate 1 to the operator's side, open the middle layer plate 3, place the two collar pads at both ends of the first splicing groove 12 respectively, and cover the zipper groove 11. Then place the collar cut piece on the collar pad to cover the zipper groove 11 and the first splicing groove 12.

[0058] Step 3: Refer to Figure 4Cover the middle layer 3 with the collar bottom plate 1, open the collar top plate 4, insert the zipper teeth along the zipper groove 11, and align the zipper fabric with the zipper limit strip 31. Then cover the zipper header with the zipper and align it with the zipper header limit strip 32. Next, cover the collar top plate 4 with the middle layer 3, and sew the pattern line along the zipper through groove 41 on the collar top plate 4 corresponding to the zipper groove 11, so that the collar pad, collar piece, zipper and zipper header are sewn together.

[0059] Step Four: Refer to Figure 5 and Figure 6 Open the inner collar top plate, place two layers of downproof fabric and knitted fabric pieces on the inner collar bottom plate 2 in sequence, and cover the inner collar sewing groove 21 and the second splicing groove 22. Then cover the inner collar top plate with the inner collar bottom plate 2, and sew the pattern line along the inner collar through groove 61 set on the inner collar top plate corresponding to the inner collar sewing groove 21 so that the two layers of downproof fabric and knitted fabric pieces are sewn together.

[0060] Step 5: Refer to Figures 7 to 9 Flip the outer collar base plate 1 towards the inner collar base plate 2 so that the first splicing groove 12 on the outer collar base plate 1 coincides with the second splicing groove 22 on the inner collar base plate 2. Sew the pattern line along the splicing groove track so that the outer collar and inner collar are spliced ​​together.

[0061] Step Six: Open the template, remove the sewn collar, and turn it inside out.

[0062] Fill the down-filled pouch formed by two layers of down-proof fabric with down, and then sew it to the garment body to complete the stand-up collar on the down jacket. Furthermore, after steps three and four, lines can be drawn using the marking groove 14 to facilitate subsequent sewing and positioning with the garment body.
