Description

Technical Field

[0001] This invention relates to the field of clothing technology, and in particular to a method and apparatus for solving the problem of insufficient fabric at the obliquely raised edge. Background Technology

[0002] Thermal clothing is essential for protecting people from the cold in winter. Currently, thermal clothing designs on the market can be broadly categorized into horizontally shaped and non-horizontally shaped (diagonally shaped) designs. There are two common methods for pattern making for horizontally shaped thermal clothing: one is to allow for shrinkage by vertically increasing the allowance after the basic pattern is drawn, thus mitigating the shrinkage issue after the fabric is shaped and returning to its original design; the other is to incorporate the shrinkage rate data during the pattern making process to directly obtain the final pattern before proceeding to the next step. If the aforementioned two methods are used to draw a diagonally shaped pattern, it will result in uneven shrinkage of the fabric after the shaped fabric is shaped, preventing it from returning to the intended design.

[0003] Because the fabric shrinks back along the quilting direction after being lifted, the conventional horizontal shrinkage allowance will alter the original shape of the diagonal cut after the fabric is lifted. With the lift height remaining constant, the greater the diagonal angle, the greater the deformation of the cut. If subsequent steps are forcibly performed, the entire garment will be deformed and unable to return to its original shape. Therefore, the method of horizontal shrinkage allowance is not suitable for compensating for insufficient fabric at the edge after a diagonal lift. Figure 1 The actual schematic diagram shown shows that the overall shape is deformed due to the allowance for reduction in the horizontal direction. Summary of the Invention

[0004] The purpose of this invention is to overcome the problem of insufficient fabric at the obliquely raised edge by providing a method and apparatus for solving the problem of insufficient fabric at the obliquely raised edge.

[0005] The objective of this invention can be achieved through the following technical solutions:

[0006] One of the technical solutions of the present invention is to provide a method for solving the problem of insufficient fabric at the obliquely raised edge, comprising the following steps:

[0007] S1. Determine the first shape of the first side fabric and the second side fabric, and the first position of a number of oblique quilting lines on the first side fabric and the second side fabric after tossing, wherein the fabric between each pair of adjacent oblique quilting lines is a unit sub-region.

[0008] S2. Based on the height to be thrown and the distance between adjacent diagonal quilts after the throw, determine the actual length between each pair of adjacent diagonal quilts perpendicular to the direction of the diagonal quilt. Move several diagonal quilts to the second position in sequence so that the spacing is the actual length, and redetermine the unit sub-region.

[0009] S3. Based on the redefined unit sub-region, redefine the second shape of the first side fabric and / or the second side fabric, and cut according to the discard requirements;

[0010] S4. Arrange the cut first and second side fabrics neatly in order from top to bottom. Fix the second position of the redefined diagonal quilting lines according to the first position of the diagonal quilting lines, and seal the openings at both ends.

[0011] In some specific embodiments, the height to be thrown includes the height of the first side fabric thrown and / or the height of the second side fabric thrown; the throwing requirement includes the throwing of the first side fabric and / or the throwing of the second side fabric.

[0012] In some specific embodiments, in step S2, the actual length between each pair of adjacent diagonal quilting lines perpendicular to the direction of the diagonal quilting line is as shown in formula (1):

[0013]

[0014] Where S is the arc length between any two adjacent diagonal quilts after the throw, which is the actual length between any two adjacent diagonal quilts perpendicular to the direction of the diagonal quilt; h is the height to be thrown; and l is half the distance between any two adjacent diagonal quilts after the throw.

[0015] In some specific implementations, in step S2, the step of sequentially moving several oblique quilting lines to the second position so that the spacing is the actual length and redefining the unit sub-region specifically includes: translating the oblique quilting line position along the same direction perpendicular to the oblique quilting line so that the actual length between two adjacent oblique quilting lines perpendicular to the oblique quilting line direction is S; connecting the two endpoints of the two adjacent oblique quilting lines respectively; and redefining the unit sub-region between the two adjacent oblique quilting lines.

[0016] In some specific embodiments, the moved oblique quilting lines are moved by a distance A in the horizontal direction and a distance B in the vertical direction relative to the previous oblique quilting line, as shown in equation (2):

[0017]

[0018] Where A is the horizontal distance moved by several oblique quilting lines to the second position, such that the spacing is the actual length; B is the vertical distance moved by several oblique quilting lines to the second position, such that the spacing is the actual length; S is the arc length between every two adjacent oblique quilting lines after being thrown up, that is, the actual length between every two adjacent oblique quilting lines perpendicular to the oblique quilting line direction; 2l is the distance between every two adjacent oblique quilting lines after being thrown up; θ is the angle between the oblique quilting lines and the horizontal direction.

[0019] In some specific embodiments, step S4, which involves arranging the cut first and second side fabrics neatly in a top-to-bottom order, fixing the second positions of the redefined diagonal quilting lines according to the first positions of the diagonal quilting lines, and sealing the openings at both ends, specifically includes:

[0020] Arrange the cut first and second side fabrics neatly from top to bottom. Fix the second position of the several diagonal quilting lines according to the first position of the several diagonal quilting lines, and seal one side, leaving a filling opening.

[0021] Fill and toss according to the pre-filled material, and then seal the filling port.

[0022] In some specific embodiments, the pre-filled material is a material that can store still air.

[0023] In some specific embodiments, the pre-filled material includes gas, down, and silk.

[0024] In some specific embodiments, the first side fabric and the second side fabric are fabrics woven from tightly woven yarns that reduce airflow.

[0025] The second technical solution of the present invention provides a device for solving the problem of insufficient fabric at the obliquely raised edge, used to implement the method for solving the problem of insufficient fabric at the obliquely raised edge as described in one of the above technical solutions, including:

[0026] The initial fabric and quilting determination module is used to determine the first shape of the first side fabric and the second side fabric, and the first position of a number of oblique quilting lines on the first side fabric and the second side fabric after tossing, wherein the fabric between each pair of adjacent oblique quilting lines is a unit sub-region.

[0027] The final fabric and quilting determination module is used to determine the actual length between each pair of adjacent diagonal quilting lines perpendicular to the diagonal quilting line direction based on the height to be thrown and the distance between adjacent diagonal quilting lines after the throw. It then moves several diagonal quilting lines to the second position in sequence so that the spacing is the actual length, and redetermines the unit sub-region.

[0028] The fabric selection and cutting module is used to redefine the second shape of the first side fabric and / or the second side fabric based on the redefined unit sub-region, and to cut it according to the throwing requirements.

[0029] The positioning and sewing module is used to arrange the cut first and second side fabrics neatly in order from top to bottom, fix the second position of several redefined diagonal quilting lines according to the first position of several diagonal quilting lines, and seal the openings at both ends.

[0030] Compared with the prior art, the present invention has the following beneficial effects:

[0031] This invention provides a method for pre-complementing the missing material at the edge after a diagonal quilting process. This solves the technical problem of uneven shrinkage of the fabric following the diagonal quilting direction, leading to garment deformation and preventing the achievement of the original design. Because this invention pre-complements the shrinkage allowance, it reduces the difficulty of subsequent processes, lowers costs, increases production efficiency, and preserves the original design to the greatest extent possible. Attached Figure Description

[0032] Figure 1 This is a diagram illustrating the overall shape deformation of the fabric caused by the allowance for shrinkage in the horizontal direction.

[0033] Figure 2 This is a schematic diagram of an obliquely thrown structure according to an embodiment of the present invention. Detailed Implementation

[0034] To make the objectives, technical solutions, and advantages of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention. The term "comprising" and its variations as used herein indicate open-ended inclusion, that is, "including but not limited to," and may also include other explicit and implicit definitions below. In the following embodiments, unless otherwise specified, the functional components or structures are conventional components or structures used in the art to achieve the corresponding functions.

[0035] like Figure 2 As shown, Embodiment 1 of the present invention provides a method for solving the problem of insufficient fabric at the obliquely raised edge, comprising the following steps:

[0036] S1. Determine the first shape of the first side fabric and the second side fabric, and the first position of a number of oblique quilting lines on the first side fabric and the second side fabric after tossing, wherein the fabric between each pair of adjacent oblique quilting lines is a unit sub-region.

[0037] The quilting lines at the first position are: the 1st diagonal quilting line, the 2nd diagonal quilting line, the 3rd diagonal quilting line, ... the (n-1)th diagonal quilting line and the nth diagonal quilting line.

[0038] S2. Based on the height to be thrown and the distance between adjacent diagonal quilts after the throw, determine the actual length between each pair of adjacent diagonal quilts perpendicular to the direction of the diagonal quilt; move several diagonal quilts to the second position in sequence so that the spacing is the actual length, and redetermine the unit sub-region.

[0039] The diagonal quilting lines that move sequentially to the second position are as follows: the second diagonal quilting line becomes the second' diagonal quilting line after moving, the third diagonal quilting line becomes the third' diagonal quilting line after moving, ... the (n-1)th diagonal quilting line becomes the (n-1)' diagonal quilting line after moving, and the nth diagonal quilting line becomes the n' diagonal quilting line after moving.

[0040] S3. Based on the redefined unit sub-region, redefine the second shape of the first side fabric or the second side fabric, and cut it according to the throwing requirements.

[0041] S4. Arrange the cut first and second side fabrics neatly in order from top to bottom. Fix the second position of the redefined diagonal quilting lines according to the first position of the diagonal quilting lines, and seal the openings at both ends.

[0042] The technical solution of this embodiment is for a scenario where only one side of the fabric is thrown up. For example, when the height to be thrown up is the height to be thrown up by the first side of the fabric, then the first side of the fabric is thrown up, and the second side of the fabric is not thrown up. Then the first side of the fabric is cut according to the second shape, and the second side of the fabric is cut according to the first shape. The length of the first-side fabric is redefined based on the characteristic that the length of fabric perpendicular to the diagonal quilting direction between each two diagonal quilting lines on the first side is longer than that between each two diagonal quilting lines on the second side. The actual distance between adjacent diagonal quilting lines on the first side and the second positions of several diagonal quilting lines are determined based on the height of the throw between adjacent diagonal quilting lines on the first side and the distance between adjacent diagonal quilting lines after the throw. During sewing, the second positions of several diagonal quilting lines on the first side and the first positions of several diagonal quilting lines on the second side are fixed by a guide rail, creating several three-dimensional spaces composed of adjacent diagonal quilting lines that satisfy the throw height. These three-dimensional spaces are filled with a substance that stores still air.

[0043] When the height to be thrown is the height to be thrown by the second side of the fabric, then the second side of the fabric is thrown up, and the first side of the fabric is not thrown up. Then the second side of the fabric is cut according to the second shape, and the first side of the fabric is cut according to the first shape. The length of the second-side fabric is redefined based on the characteristic that the fabric between each two diagonal quilting lines on the second-side fabric is longer than the fabric between each two diagonal quilting lines on the first-side fabric. The actual distance between adjacent diagonal quilting lines on the second-side fabric and the second positions of several diagonal quilting lines are determined based on the height of the throw between adjacent diagonal quilting lines on the second-side fabric and the distance between adjacent diagonal quilting lines after the throw. During sewing, the second positions of several diagonal quilting lines on the second-side fabric are fixed to the first positions of several diagonal quilting lines on the first-side fabric by a guide rail, creating several three-dimensional spaces composed of adjacent diagonal quilting lines that satisfy the throw height. These three-dimensional spaces are filled with a substance that stores still air.

[0044] According to the technique of raising only one side of the fabric provided in this embodiment, the sewing structure of clothing or home textiles such as quilts and blankets is obtained by compensating for the lack of fabric between every two adjacent diagonal quilting lines on the side of the fabric raised at the height of the fabric, so that the first side fabric and the second side fabric can fit together when sewing, and the original design shape is preserved to the greatest extent after sewing.

[0045] In one embodiment, in step S2, the actual length between each pair of adjacent diagonal quilting lines perpendicular to the direction of the diagonal quilting line is as shown in formula (1):

[0046]

[0047] Where S is the arc length between any two adjacent diagonal quilts after the throw, which is the actual length between any two adjacent diagonal quilts perpendicular to the direction of the diagonal quilt; h is the height to be thrown; and l is half the distance between any two adjacent diagonal quilts after the throw.

[0048] The derivation of formula (1) is as follows:

[0049] like Figure 2 As shown, EF is taken as the second oblique quilting line l EF Using GH as the second oblique quilting line EF The adjacent first diagonal quilting line l GH Draw a perpendicular line intersecting the second oblique quilting line l. EF and the first oblique quilting line l GH The line segment that intersects with the second oblique quilting line l EF and the first oblique quilting line l GH The intersection points are P and Q; draw an arc with P and Q as endpoints, and the center of the arc PQ is O.

[0050] Let S be the first oblique quilting line l GH and the second oblique quilting line l EF The arc length between them is the POQ circle arc length, and 2l is the first oblique quilting line l. GH and the second oblique quilting line l EF The distance between them is the length of PQ, h is the distance between the line segments from O to PQ, which is the height to be thrown, R is the radius of the circle containing the PQ arc, and 2α is the central angle of the PQ arc.

[0051] According to the intersecting chords theorem, (2R-h)h = l 2 ,but

[0052] because Substituting R, then

[0053] arc length

[0054] In one implementation, in step S2, several oblique quilting lines are sequentially moved to the second position so that the spacing is the actual length, and the unit sub-region is redefined, specifically as follows:

[0055] The position of the oblique quilting is translated in the same direction perpendicular to the oblique quilting, so that the actual length between two adjacent oblique quilting lines perpendicular to the oblique quilting direction is S. The two endpoints of the two adjacent oblique quilting lines are connected respectively, and the unit sub-region between the two adjacent oblique quilting lines is redefined.

[0056] like Figure 2 As shown, with the first oblique quilting line l GH Starting from the position, translate the second oblique quilting line l in the same direction perpendicular to the oblique quilting line. EF Position to the 2nd diagonal quilting line l E’F’ Position, such that the first oblique quilting line l GH With the 2nd oblique quilting line l E’F’ The actual length between them perpendicular to the direction of the diagonal quilting is S, and they are connected to the first diagonal quilting l. GH With the 2nd oblique quilting line l E’F’ Redefine the first diagonal quilting line at both ends. GH With the 2nd oblique quilting line l E’F’The unit sub-region between them is the quadrilateral E'F'HG region; continue to translate the position of the 3rd oblique quilting line to the position of the 3' oblique quilting line in the same direction perpendicular to the oblique quilting line, so that the actual length between the 3rd oblique quilting line and the 2' oblique quilting line perpendicular to the oblique quilting line is S. Connect the two endpoints of the 3rd oblique quilting line and the 2' oblique quilting line respectively, and redefine the unit sub-region between the 3rd oblique quilting line and the 2' oblique quilting line; similarly, translate all the remaining oblique quilting lines in the same direction perpendicular to the oblique quilting line, so that the actual length between two adjacent oblique quilting lines perpendicular to the oblique quilting line is S. Connect the two endpoints of two adjacent oblique quilting lines respectively, and redefine the unit sub-region between two adjacent oblique quilting lines.

[0057] In one embodiment, the first oblique quilting line l GH As a fixed line, straighten the second diagonal quilting line l. EF Then located at the 2' oblique quilting line l E’F’ At point 2, the oblique quilting line l E’F’ Relative to the second oblique quilting line l EF The distance was moved by a distance A in the horizontal direction and by a distance B in the vertical direction, as shown in equation (2):

[0058]

[0059] Where A is the second oblique quilting line l EF Move to the second position, i.e., the 2nd diagonal quilting line l E’F’ This causes the horizontal line to move a distance equal to the actual length of the spacing; B is the second diagonal quilting line l EF Move to the second position, i.e., the 2nd diagonal quilting line l E’F’ The vertical distance s is the actual length of the quilted line; S is the arc length between every two adjacent diagonal quilted lines after the throw, which is the actual length between every two adjacent diagonal quilted lines perpendicular to the direction of the diagonal quilted line; 2l is the distance between every two adjacent diagonal quilted lines after the throw; θ is the angle between the diagonal quilted line and the horizontal line.

[0060] Then when the second oblique quilting line l EF Move to the second position, i.e., the 2nd diagonal quilting line l E’F’ After that, for the cloth on the side that was thrown up, the cloth portion that needs to be compensated for in the unit sub-region is quadrilateral E'F'HG - quadrilateral EFHG. Finally, the cloth portion that needs to be compensated for in the side that was thrown up is the number of unit sub-regions × the cloth portion that needs to be compensated for in the unit sub-region.

[0061] This allows for the pre-determining of the lengths of the first and second side fabrics, thus solving the technical problem of insufficient fabric at the edges due to fabric bulging during sewing. If insufficient fabric is not compensated for in the first or second side fabric, the edges of the first or second side fabric will become deformed after sewing, affecting the aesthetics and the progress of subsequent processes.

[0062] In one embodiment, step S4, which involves arranging the cut first and second side fabrics neatly in a top-to-bottom order, fixing the second positions of the reconfirmed diagonal quilting lines according to the first positions of the diagonal quilting lines, and sealing the openings at both ends, specifically includes:

[0063] Arrange the cut first and second side fabrics neatly in order from top to bottom. Fix the second position of the newly determined diagonal quilting lines according to the first position of the diagonal quilting lines, and seal one side, leaving a filling opening.

[0064] Fill and toss according to the pre-filled material, and then seal the filling port.

[0065] This technical solution includes scenarios involving gas filling, down, and silk filling. For example, in the gas filling scenario, several three-dimensional spaces are created between the first and second fabric layers during sewing. These spaces facilitate the storage of still air, and dry, still air is an excellent thermal insulator, preventing the alternation of hot and cold air and thus providing warmth. In the down filling scenario, the down has a certain loft within these three-dimensional spaces, locking in more still air, and also thickens the clothing or home textiles (such as quilts and blankets), resulting in greater warmth. In the silk filling scenario, the numerous gaps between silk fibers and the multiple pores on the surface ensure breathability. Furthermore, these pores can store air, forming an air layer between the layers of silk during the silk-pulling process. Because air has low thermal conductivity, it provides excellent warmth.

[0066] In one embodiment, both the first and second side fabrics consist of a single lining. When filled with gas, the lining is made of tightly woven yarns that reduce airflow, effectively blocking the flow of air between the interior and exterior spaces. This locks in the air, creating a relatively still environment. Dry, still air is an ideal thermal insulator, thus providing warmth. When filled with down, the tightly woven yarns provide support, allowing the down to fluff up and provide warmth. When filled with silk, the tightly woven yarns help the silk retain heat in cold weather, while maintaining its breathability in hot weather to release excess heat, keeping the temperature constant.

[0067] In one embodiment, both the first and second side fabrics consist of a lining fabric and a face fabric. When filled with gas, the lining fabric can be made of any material and function, while the face fabric is made of tightly woven yarns that reduce airflow, such as hollow polyester fibers. This fabric effectively blocks the flow of air between the interior and exterior spaces, thus achieving relative air stillness and providing warmth. When filled with down or silk, the lining fabric can be made of high-density fabric coated with down-proof adhesive, while the face fabric, also made of tightly woven yarns that reduce airflow, such as hollow polyester fibers, provides support and creates a space that prevents down leakage and water penetration. Furthermore, it effectively blocks the flow of air between the interior and exterior spaces, achieving relative air stillness and providing dual warmth.

[0068] Embodiment 2 of the present invention provides another method for solving the problem of insufficient fabric at the obliquely raised edge, comprising the following steps:

[0069] S1. Determine the first shape of the first side fabric and the second side fabric, and the first position of a number of oblique quilting lines on the first side fabric and the second side fabric after tossing, wherein the fabric between each pair of adjacent oblique quilting lines is a unit sub-region.

[0070] The quilting lines at the first position are: the 1st diagonal quilting line, the 2nd diagonal quilting line, the 3rd diagonal quilting line, ... the (n-1)th diagonal quilting line and the nth diagonal quilting line.

[0071] S2. Based on the height to be thrown and the distance between adjacent diagonal quilts after the throw, determine the actual length between each pair of adjacent diagonal quilts perpendicular to the direction of the diagonal quilt; move several diagonal quilts to the second position in sequence so that the spacing is the actual length, and redetermine the unit sub-region.

[0072] The diagonal quilting lines that move sequentially to the second position are as follows: the second diagonal quilting line becomes the second' diagonal quilting line after moving, the third diagonal quilting line becomes the third' diagonal quilting line after moving, ... the (n-1)th diagonal quilting line becomes the (n-1)' diagonal quilting line after moving, and the nth diagonal quilting line becomes the n' diagonal quilting line after moving.

[0073] S3. Based on the redefined unit sub-region, redefine the second shape of the first side fabric and the second side fabric, and cut according to the throwing requirements;

[0074] S4. Arrange the cut first and second side fabrics neatly in order from top to bottom. Fix the second position of the redefined diagonal quilting lines according to the first position of the diagonal quilting lines, and seal the openings at both ends.

[0075] The technical solution of this embodiment is a scenario where fabrics on both sides are thrown up. The heights to be thrown up are the heights of the first side fabric and the second side fabric. Then, both the first side fabric and the second side fabric need to be cut according to the second shape. Based on the height of the throw between two adjacent diagonal quilting lines on the first side fabric and the distance between two adjacent diagonal quilting lines after the throw, the actual distance between adjacent diagonal quilting lines on the first side fabric and the second position of several diagonal quilting lines are determined. Similarly, based on the height of the throw between two adjacent diagonal quilting lines on the second side fabric and the distance between two adjacent diagonal quilting lines after the throw, the actual distance between two adjacent diagonal quilting lines on the second side fabric and the second position of several diagonal quilting lines are determined. During sewing, the second positions of several diagonal quilting lines on the first side fabric and the second positions of several diagonal quilting lines on the second side fabric are fixed by a guideline, creating several three-dimensional spaces composed of two adjacent diagonal quilting lines that satisfy the throw height. The three-dimensional spaces are filled with a substance that stores still air.

[0076] According to the fabric lifting technique provided in this embodiment 2, the fabric sewing structure or home textile sewing structure such as quilts and blankets obtained by lifting the fabric on both sides has a compensation for the lack of fabric between each two adjacent diagonal quilting lines in the direction perpendicular to the diagonal quilting line, so that the first side fabric and the second side fabric can fit together when sewing, and the original design shape is preserved to the greatest extent after sewing.

[0077] In one embodiment, in step S2, the actual length between each pair of adjacent diagonal quilting lines perpendicular to the direction of the diagonal quilting line is as shown in formula (1):

[0078]

[0079] Where S is the arc length between any two adjacent diagonal quilts after the throw, which is the actual length between any two adjacent diagonal quilts perpendicular to the direction of the diagonal quilt; h is the height to be thrown; and l is the general distance between any two adjacent diagonal quilts after the throw.

[0080] The derivation of formula (1) is as follows:

[0081] like Figure 2 Taking the case where the fabric is thrown up on one side as an example, let EF be the second diagonal quilting line. EF Using GH as the first oblique quilting line adjacent to the second oblique quilting line. GH Draw a perpendicular line intersecting the second oblique quilting line l. EF and the first oblique quilting line l GH The line segment that intersects with the second oblique quilting line l EF and the first oblique quilting line l GH The intersection points are P and Q; draw an arc with P and Q as endpoints, and the center of the arc PQ is O.

[0082] Let S be the first oblique quilting line l GH and the second oblique quilting line l EF The arc length between them is the POQ circle arc length, and 2l is the first oblique quilting line l. GH and the second oblique quilting line l EF The distance between them is the length of PQ, h is the distance between the line segments from O to PQ, which is the height to be thrown, R is the radius of the circle containing the PQ arc, and 2α is the central angle of the PQ arc.

[0083] According to the intersecting chords theorem, (2R-h)h = l 2 ,but

[0084] because Substituting R, then

[0085] arc length

[0086] In one implementation, in step S2, several oblique quilting lines are sequentially moved to the second position so that the spacing is the actual length, and the unit sub-region is redefined, specifically as follows:

[0087] The position of the oblique quilting is translated in the same direction perpendicular to the oblique quilting, so that the actual length between two adjacent oblique quilting lines perpendicular to the oblique quilting direction is S. The two endpoints of the two adjacent oblique quilting lines are connected respectively, and the unit sub-region between the two adjacent oblique quilting lines is redefined.

[0088] like Figure 2 As shown, with the first oblique quilting line l GHStarting from the position, translate the second oblique quilting line l in the same direction perpendicular to the oblique quilting line. EF Position to the 2nd diagonal quilting line l E’F’ Position, such that the first oblique quilting line l GH With the 2nd oblique quilting line l E’F’ The actual length between them perpendicular to the direction of the diagonal quilting is S, and they are connected to the first diagonal quilting l. GH With the 2nd oblique quilting line l E’F’ Redefine the first diagonal quilting line at both ends. GH With the 2nd oblique quilting line l E’F’ The unit sub-region between them is the quadrilateral E'F'HG region; continue to translate the position of the 3rd oblique quilting line to the position of the 3' oblique quilting line in the same direction perpendicular to the oblique quilting line, so that the actual length between the 3rd oblique quilting line and the 2' oblique quilting line perpendicular to the oblique quilting line is S. Connect the two endpoints of the 3rd oblique quilting line and the 2' oblique quilting line respectively, and redefine the unit sub-region between the 3rd oblique quilting line and the 2' oblique quilting line; similarly, translate all the remaining oblique quilting lines in the same direction perpendicular to the oblique quilting line, so that the actual length between two adjacent oblique quilting lines perpendicular to the oblique quilting line is S. Connect the two endpoints of two adjacent oblique quilting lines respectively, and redefine the unit sub-region between two adjacent oblique quilting lines.

[0089] In one embodiment, the first oblique quilting line l GH As a fixed line, straighten the second diagonal quilting line l. EF Then located at the 2' oblique quilting line l E’F’ At point 2, the oblique quilting line l E’F’ Relative to the second oblique quilting line l EF The distance was moved by a distance A in the horizontal direction and by a distance B in the vertical direction, as shown in equation (2):

[0090]

[0091] Where A is the second oblique quilting line l EF Move to the second position, i.e., the 2nd diagonal quilting line l E’F’ This causes the horizontal line to move a distance equal to the actual length of the spacing; B is the second diagonal quilting line l EF Move to the second position, i.e., the 2nd diagonal quilting line l E’F’ , which makes the vertical movement distance of the spacing equal to the actual length; S is the arc length between every two adjacent diagonal quilts after being thrown up, that is, the actual length between every two adjacent diagonal quilts perpendicular to the direction of the diagonal quilt; 2l is the distance between every two adjacent diagonal quilts after being thrown up; θ is the angle between the diagonal quilt and the horizontal line.

[0092] Then when the second oblique quilting line l EFMove to the second position, i.e., the 2nd diagonal quilting line l E’F’ After that, for the fabric on the side that is thrown up, the fabric portion that needs to be compensated for in the newly determined unit sub-region is quadrilateral E'F'HG - quadrilateral EFHG. Finally, the fabric portion that needs to be compensated for in the side that is thrown up is the number of unit sub-regions × the fabric portion that needs to be compensated for in the unit sub-region.

[0093] This allows for the pre-determining of the lengths of the first and second side fabrics, thus resolving the technical problem of insufficient fabric at the edges due to fabric bulging during sewing. Without compensation for insufficient fabric at the first and second side fabrics, the edges of the bulging fabrics will deform after sewing, affecting both aesthetics and the progress of subsequent processes.

[0094] In one embodiment, step S4, which involves arranging the cut first and second side fabrics neatly in a top-to-bottom order, fixing the second position of the reconfirmed diagonal quilting lines according to the first positions of several diagonal quilting lines, and sealing the openings at both ends, specifically includes:

[0095] Arrange the cut first and second side fabrics neatly in order from top to bottom. Fix the second position of the newly determined diagonal quilting lines according to the first position of the diagonal quilting lines, and seal one side, leaving a filling opening.

[0096] Fill and toss according to the pre-filled material, and then seal the filling port.

[0097] This technical solution includes scenarios involving gas filling, down, and silk filling. For example, in the gas filling scenario, several three-dimensional spaces are created between the first and second fabric layers during sewing. These spaces facilitate the storage of still air, and dry, still air is an excellent thermal insulator, preventing the alternation of hot and cold air and thus providing warmth. In the down filling scenario, the down has a certain loft within these three-dimensional spaces, locking in more still air, and also thickens the clothing or home textiles (such as quilts and blankets), resulting in greater warmth. In the silk filling scenario, the numerous gaps between silk fibers and the multiple pores on the surface ensure breathability. Furthermore, these pores can store air, forming an air layer between the layers of silk during the silk-pulling process. Because air has low thermal conductivity, it provides excellent warmth.

[0098] In one embodiment, both the first and second side fabrics consist of a single lining. When filled with gas, the lining is made of tightly woven yarns that reduce airflow, effectively blocking the flow of air between the interior and exterior spaces. This locks in the air, creating a relatively still environment. Dry, still air is an ideal thermal insulator, thus providing warmth. When filled with down, the tightly woven yarns provide support, allowing the down to fluff up and provide warmth. When filled with silk, the tightly woven yarns help the silk retain heat in cold weather, while maintaining its breathability in hot weather to release excess heat, keeping the temperature constant.

[0099] In one embodiment, both the first and second side fabrics consist of a lining fabric and a face fabric. When filled with gas, the lining fabric can be made of any material and function, while the face fabric is made of tightly woven yarns that reduce airflow, such as hollow polyester fibers. This fabric effectively blocks the flow of air between the interior and exterior spaces, thus achieving relative air stillness and providing warmth. When filled with down or silk, the lining fabric can be made of high-density fabric coated with down-proof adhesive, while the face fabric, also made of tightly woven yarns that reduce airflow, such as hollow polyester fibers, provides support and creates a space that prevents down leakage and water penetration. Furthermore, it effectively blocks the flow of air between the interior and exterior spaces, achieving relative air stillness and providing dual warmth.

[0100] Embodiment 3 of the present invention provides a device for solving the problem of insufficient fabric at the obliquely raised edge, used to implement a method for solving the problem of insufficient fabric at the obliquely raised edge as described in any of the above technical solutions, including:

[0101] The initial fabric and quilting determination module is used to determine the first shape of the first side fabric and the second side fabric, and the first position of a number of oblique quilting lines on the first side fabric and the second side fabric after tossing, wherein the fabric between each pair of adjacent oblique quilting lines is a unit sub-region.

[0102] The quilting lines at the first position are: the 1st diagonal quilting line, the 2nd diagonal quilting line, the 3rd diagonal quilting line, ... the (n-1)th diagonal quilting line and the nth diagonal quilting line.

[0103] The final fabric and quilting determination module is used to determine the actual length between each pair of adjacent diagonal quilting lines perpendicular to the diagonal quilting line direction based on the height to be thrown and the distance between adjacent diagonal quilting lines after the throw. It then moves several diagonal quilting lines to the second position in sequence so that the spacing is the actual length, and redetermines the unit sub-region.

[0104] The diagonal quilting lines that move sequentially to the second position are as follows: the second diagonal quilting line becomes the second' diagonal quilting line after moving, the third diagonal quilting line becomes the third' diagonal quilting line after moving, ... the (n-1)th diagonal quilting line becomes the (n-1)' diagonal quilting line after moving, and the nth diagonal quilting line becomes the n' diagonal quilting line after moving.

[0105] The fabric selection and cutting module is used to redefine the second shape of the first side fabric and / or the second side fabric based on the redefined unit sub-region, and to cut it according to the throwing requirements.

[0106] The positioning and sewing module is used to arrange the cut first and second side fabrics neatly in order from top to bottom, fix the second position of several redefined diagonal quilting lines according to the first position of several diagonal quilting lines, and seal the openings at both ends.

[0107] The above description of the embodiments is provided to enable those skilled in the art to understand and use the invention. It will be apparent to those skilled in the art that various modifications can be made to these embodiments, and the general principles described herein can be applied to other embodiments without inventive effort. Therefore, the present invention is not limited to the above embodiments, and any improvements and modifications made by those skilled in the art based on the disclosure of the present invention without departing from the scope of the invention should be within the protection scope of the present invention.
