Description

Technical Field

[0001] The invention relates to the technical field of clothing, and in particular to a method and a device for solving the problem of edge deficiency of thrown cloth. Background Art

[0002] Non-straight filling means cutting the surface cloth and liner cloth into predetermined shapes; drawing the predetermined filling line position on the surface cloth, and placing the cut surface cloth and two layers of liner cloth in order from top to bottom; completing the filling line according to the pre-set sewing, and then fixing the surrounding lines, and reserving the filling opening; then filling according to the predetermined filling weight and completing the sealing.

[0003] After filling, the fabric will bulge. Compared with the flat fabric, the projection of the bulged fabric on the plane is a concave arc, that is, after the fabric is filled with down, a cylindrical parabolic surface will be formed, which will cause the edge of the cut piece to sag. The sag makes the fabric shorter than the length of the flat fabric, and there is a missing amount, which makes the seam allowance smaller. The more down is filled, the more bulging the fabric, and the larger the concave arc, which will be limited to deviate from the pre-estimated sewing position. At this time, if the sewing is done, it will be shorter than the pre-measured length, affecting the correct size. Figure 1-3 shown. Summary of the invention

[0042] In order to make the purpose, technical solutions and advantages of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention. The term "including" and its variations used in this article represent open inclusion, that is, "including but not limited to", and other explicit and implicit definitions may also be included below.

[0043] In the following embodiments, unless otherwise specified, functional components or structures are conventional components or conventional structures used in the art to achieve corresponding functions.

[0044] like Figure 4-6 As shown, the first embodiment of the present invention provides a method for solving the edge shortage of thrown cloth, comprising the following steps:

[0045] S1, determining a predetermined shape of a first side fabric 1 and a second side fabric 2, and positions of a plurality of quilting lines on the first side fabric 1 and the second side fabric 2;

[0046] S2. Determine the compensation fabric length perpendicular to the quilting line direction between every two quilting lines according to the height to be thrown up and the distance between adjacent quilting lines after being thrown up;

[0047] S3, cutting the first side fabric 1 and the second side fabric 2 according to the predetermined shapes of the first side fabric 1 and the second side fabric 2 in step S1 and the compensation fabric length in step S2;

[0048] S4, the first side fabric 1 and the second side fabric 2 cut in step S3 are neatly arranged in order from top to bottom, the quilting threads are fixed according to the positions of the quilting threads predetermined in step S1, and the openings at both ends are sealed.

[0049] The technical solution of the first embodiment of the present invention is a scenario in which only one side of the fabric is thrown up, including scenarios in which no objects are filled and scenarios in which objects are filled. Exemplarily, in the scenario in which no objects are filled, when the height to be thrown up is the height thrown up by the first side fabric 1, the fabric perpendicular to the quilting direction between every two quilting lines on the first side fabric 1 is longer than the fabric perpendicular to the quilting direction between every two quilting lines on the second side fabric 2, so that the edges of the second side fabric 2 and the first side fabric 1 can be matched during sewing, and a plurality of three-dimensional spaces composed of every two quilting lines generated between the second side fabric 2 and the first side fabric 1 are convenient for storing still air, and dry still air is the best thermal insulation material, which prevents the alternation of cold and hot air, thereby achieving a warming effect.

[0050] In one embodiment, Figure 5-6 As shown, the compensation fabric length perpendicular to the quilting line direction between every two quilting lines on the first side fabric 1 of the throwing height is as shown in formula (1):

[0051]

[0052] Among them, a represents the length of the highest point of one side of the fabric; b represents the missing fabric length perpendicular to the quilting direction between every two quilting lines after the fabric is thrown up, that is, the fabric length that needs to be compensated; h represents the length of the inclined hypotenuse at the highest point of the edge of the fabric after the fabric is thrown up.

[0053] The length h of the inclined hypotenuse at the highest point of the edge of the fabric is as shown in formula (2):

[0054]

[0055] Wherein, R represents the radius; l represents half of the distance between every two quilting lines.

[0056] The derivation process of formula (2) is as follows:

[0057] Assume that the chord length (the distance between every two quilting lines) is 2l, the chord height (the inclined hypotenuse of the highest point of the edge) is h, and the radius of the circle where the chord length and chord height are located is R,

[0058] According to the intersecting chord theorem, we can get (2R-h)h=l 2 , after simplification, we get formula (2).

[0059] Thus, the notch at both ends of the first side fabric 1 perpendicular to the quilting line direction between every two quilting lines can be determined in advance, thereby solving the technical problem of edge notch caused by fabric bulging during sewing. If the first side fabric 1 is not compensated for the fabric notch, the edge of the bulging first side fabric 1 cannot match the edge of the second side fabric 2 after sewing, resulting in a dent on one side of the first side fabric 1, affecting the appearance and the progress of subsequent processes.

[0060] In another embodiment, in step S4, the first side fabric 1 and the second side fabric 2 cut in step S3 are neatly arranged in order from top to bottom, the quilting threads are fixed according to the positions of the plurality of quilting threads predetermined in step S1, and the openings at both ends are sealed, specifically comprising:

[0061] The cut first side fabric 1 and the second side fabric 2 are neatly arranged in order from top to bottom, fixed according to the positions of a predetermined number of quilting threads, and sealed on one side, leaving a filling opening;

[0062] Fill the down according to the pre-filled amount and seal the filling opening.

[0063] This technical solution of filling down makes the down have a certain fluffiness in the space formed by adjacent quilting lines, locking in more static air. On the other hand, it also thickens the garment, making it more warm.

[0064] In one embodiment, the first side fabric 1 and the second side fabric 2 are both made of only one piece of lining fabric. When not filled with down, the lining fabric is a fabric woven from tight yarns that reduce air flow, and has the function of blocking the air in the three-dimensional space from the external air flow, locking the air in the three-dimensional space, thereby achieving relative stillness of the air, and dry still air is the best thermal insulation material, thereby playing a role in keeping warm. When filled with down, the fabric woven from tight yarns that reduce air flow has a space with a certain supporting force, so that the down becomes fluffy in the space, thereby playing a role in keeping warm.

[0065] In one embodiment, the first side fabric 1 and the second side fabric 2 are both a piece of lining fabric and a piece of surface fabric. When not filled with down, the lining fabric is a fabric of any material and function, and the surface fabric is a fabric woven from tight yarns that reduce air flow, such as a fabric woven from hollow polyester fibers, which has the function of blocking the air in the three-dimensional space from circulating with the outside air, thereby achieving relative stillness of the air and playing a role in keeping warm. When filled with down, the lining fabric can be made of high-density fabric coated with anti-down glue, and the surface fabric is a fabric woven from tight yarns that reduce air flow, such as a fabric woven from hollow polyester fibers, which has a space of support, which, on the one hand, makes the fabric have the performance of preventing down dew and water seepage, and on the other hand, makes the fabric have the function of blocking the air in the three-dimensional space from circulating with the outside air, thereby achieving relative stillness of the air and playing a dual role in keeping warm.

[0066] The fabric sewing structure obtained by the technical method of throwing up only one side of the fabric provided in the first embodiment is as follows: Figure 4 As shown, the ends of the fabric perpendicular to the quilting line direction between every two quilting lines on the side of the fabric at the thrown-up height are compensated for the lack of allowance, so that the two ends of the first side fabric 1 and the second side fabric 2 can match each other when sewn, and the original design shape is retained to the greatest extent after sewing.

[0067] Embodiment 2 of the present invention provides another method for solving the problem of edge deficiency of thrown-up cloth, comprising the following steps:

[0068] S1, determining a predetermined shape of a first side fabric 1 and a second side fabric 2, and positions of a plurality of quilting lines on the first side fabric 1 and the second side fabric 2;

[0069] S2. Determine the compensation fabric length perpendicular to the quilting line direction between every two quilting lines according to the height to be thrown up and the distance between adjacent quilting lines after being thrown up;

[0070] S3, cutting the first side fabric 1 and the second side fabric 2 according to the predetermined shapes of the first side fabric 1 and the second side fabric 2 in step S1 and the compensation fabric in step S2;

[0071] S4, the first side fabric 1 and the second side fabric 2 cut in step S3 are neatly arranged in order from top to bottom, the quilting threads are fixed according to the positions of the quilting threads predetermined in step S1, and the openings at both ends are sealed.

[0072] The technical solution of the second embodiment of the present invention is a scenario in which fabrics on both sides are thrown up, including scenarios in which objects are not filled and scenarios in which objects are filled. Exemplarily, in a scenario in which no objects are filled, when the height to be thrown up is the sum of the heights thrown up by the first side fabric 1 and the second side fabric 2, compensation fabrics perpendicular to the quilting lines are provided between every two quilting lines on the second side fabric 2 and the first side fabric 1 so that the edges of the second fabric 2 and the first side fabric 1 can be matched during sewing. A plurality of three-dimensional spaces composed of every two quilting lines generated between the second side fabric 2 and the first side fabric 1 are convenient for storing still air, and dry still air is the best thermal insulation material, which prevents the alternation of cold and hot air, thereby achieving a warming effect.

[0073] In one embodiment, the compensation fabric length perpendicular to the quilting direction between every two quilting lines on the first side fabric 1 and the second side fabric 2 at the thrown height is as shown in formula (3):

[0074]

[0075] Among them, a represents the length of the highest point of the fabric on both sides; b represents the missing fabric length perpendicular to the quilting line direction between every two quilting lines after the fabric is thrown up, that is, the fabric length that needs to be compensated; h represents the length of the inclined hypotenuse at the highest point of the fabric edge after the fabric is thrown up.

[0076] In some specific embodiments, the length h of the inclined hypotenuse at the highest point of the edge of the cloth is as shown in formula (2):

[0077]

[0078] Wherein, R represents the radius; l represents half of the distance between every two quilting lines.

[0079] The length h of the inclined hypotenuse at the highest point of the edge of the fabric is as shown in formula (2):

[0080]

[0081] Wherein, R represents the radius; l represents half of the distance between every two quilting lines.

[0082] Thus, the fabric shortage between every two quilting lines on the first side fabric 1 and the second side fabric 2 perpendicular to the quilting line direction can be determined in advance, thereby solving the technical problem of edge shortage caused by fabric bulging during sewing. If the shortage compensation is not performed on the first side fabric 1 and the second side fabric 2, the edges of the bulging first side fabric 1 and the second side fabric 2 cannot match after sewing, resulting in a dent on the side where the fabric is missing, which affects the appearance and the progress of subsequent processes.

[0083] In another embodiment, in step S4, the first side fabric 1 and the second side fabric 2 cut in step S3 are neatly arranged in order from top to bottom, the quilting threads are fixed according to the positions of the plurality of quilting threads predetermined in step S1, and the openings at both ends are sealed, specifically comprising:

[0084] The cut first side fabric 1 and the second side fabric 2 are neatly arranged in order from top to bottom, fixed according to the positions of a predetermined number of quilting threads, and sealed on one side, leaving a filling opening;

[0085] Fill the down according to the pre-filled amount and seal the filling opening.

[0086] This technical solution of filling down makes the down have a certain fluffiness in the space formed by adjacent quilting lines, locking in more static air. On the other hand, it also thickens the garment, making it more warm.

[0087] In one embodiment, the first side fabric 1 and the second side fabric 2 are both made of only one piece of lining fabric. When not filled with down, the lining fabric is a fabric woven from tight yarns that reduce air flow, and has the function of blocking the air in the three-dimensional space from the external air flow, locking the air in the three-dimensional space, thereby achieving relative stillness of the air, and dry still air is the best thermal insulation material, thereby playing a role in keeping warm. When filled with down, the fabric woven from tight yarns that reduce air flow has a space with a certain supporting force, so that the down becomes fluffy in the space, thereby playing a role in keeping warm.

[0088] In one embodiment, the first side fabric 1 and the second side fabric 2 are both a piece of lining fabric and a piece of surface fabric. When not filled with down, the lining fabric is a fabric of any material and function, and the surface fabric is a fabric woven from tight yarns that reduce air flow, such as a fabric woven from hollow polyester fibers, which has the function of blocking the air in the three-dimensional space from circulating with the outside air, thereby achieving relative stillness of the air and playing a role in keeping warm. When filled with down, the lining fabric can be made of high-density fabric coated with anti-down glue, and the surface fabric is a fabric woven from tight yarns that reduce air flow, such as a fabric woven from hollow polyester fibers, which has a space of support, which, on the one hand, makes the fabric have the performance of preventing down dew and water seepage, and on the other hand, makes the fabric have the function of blocking the air in the three-dimensional space from circulating with the outside air, thereby achieving relative stillness of the air and playing a dual role in keeping warm.

[0089] According to the technical method for throwing up the fabrics on both sides provided in the second embodiment, the fabrics on both sides with the thrown-up height are compensated for by the fabrics perpendicular to the quilting line direction between every two quilting lines, so that the edges of the fabrics on both sides can be matched during sewing, and the original design shape is retained to the greatest extent after sewing.
