A down jacket based on trapezoidal down filling and splicing

Abstract

This utility model claims protection for a down jacket based on trapezoidal down filling and splicing, comprising an outer fabric, a lining fabric, and a inner fabric. The outer edges of the lining fabric and the outer fabric are sewn together to form a down filling lining, which has a down filling cavity. The lining fabric and the outer fabric are connected by a first trapezoidal quilting line, which extends horizontally and is arranged linearly vertically to form several strips, thereby dividing the down filling cavity into several strip-shaped down cavities. The outer fabric is located on the side of the lining fabric away from the inner fabric and is connected to the down filling lining by a second trapezoidal quilting line, which extends horizontally and is arranged linearly vertically to form several strips. The second trapezoidal quilting line and the first trapezoidal quilting line are staggered to divide the strip-shaped down cavities into several smaller down cavities. Compared with ordinary horizontal straight quilting, the trapezoidal quilting line forms a stable support between the lining fabric and the outer fabric, which can effectively fix the down filling and solve the problems of easy displacement and clumping of traditional quilting.

Description

Technical Field

[0001] This utility model relates to the field of clothing technology, specifically to a down jacket based on trapezoidal down filling and splicing. Background Technology

[0002] Down jackets typically consist of an outer fabric, a lining, and a inner lining. To improve warmth and comfort, down jackets utilize zoned filling, allowing different areas to provide varying levels of warmth and meet the body's specific needs in different parts of the body. Current down jacket quilting is usually straight-lined, but this traditional quilting design lacks both functionality and style. Utility Model Content

[0003] In view of the shortcomings of the existing technology, this utility model proposes a down jacket based on trapezoidal down filling and splicing. The trapezoidal quilting makes the down jacket more supportive, stable and warmer.

[0004] The technical solution of this utility model is as follows:

[0005] A down jacket based on trapezoidal down filling and splicing includes an outer fabric, a lining fabric, and a inner fabric. The outer edges of the lining fabric and the outer fabric are sewn together to form a down lining. The down lining has a down filling cavity. The lining fabric and the outer fabric are connected by a first trapezoidal quilting line. The first trapezoidal quilting line extends along the horizontal line and is arranged linearly along the vertical line to form several strips, thereby dividing the down filling cavity into several strip-shaped down cavities.

[0006] Each first trapezoidal trajectory quilting line includes a first lower horizontal line, a first upper diagonal line, a first upper horizontal line, and a first lower diagonal line that are connected in a sequential loop;

[0007] The outer fabric is located on the side of the inner fabric away from the lining fabric. The outer fabric is connected to the down inner fabric through the second trapezoidal quilting. The second trapezoidal quilting extends along the horizontal line and is arranged linearly along the vertical line into several strips. The second trapezoidal quilting and the first trapezoidal quilting are staggered to divide the strip down cavity into several small down cavities.

[0008] Each second trapezoidal quilting line includes a second lower horizontal line, a second upper diagonal line, a second upper horizontal line, and a second lower diagonal line that are connected in a sequential loop.

[0009] In summary, the above technical solution has the following beneficial effects: The trapezoidal quilting geometry formed by the sequentially connected first lower horizontal line, first upper diagonal line, first upper horizontal line, and first lower diagonal line provides stable support between the inner and outer fabrics, effectively securing the down filling and solving the problems of displacement and clumping associated with traditional quilting. Furthermore, the trapezoidal quilting increases the stitch density by 30% and the stitch strength by 25% compared to traditional designs, significantly enhancing the structural stability of the down jacket. Additionally, the trapezoidal quilting design ensures more even stress distribution on the stitches, reducing localized pressure and lowering the risk of stitch breakage by 40%.

Detailed Implementation

[0014] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments. Identical components are indicated by the same reference numerals. It should be noted that the terms "front," "rear," "left," "right," "upper," and "lower" used in the following description refer to directions in the accompanying drawings, and the terms "bottom surface," "top surface," "inner," and "outer" refer to directions toward or away from the geometric center of a specific component, respectively.

[0015] like Figures 1-3As shown, a down jacket based on trapezoidal down filling and splicing includes an outer fabric 10, a lining fabric, and a inner fabric. The outer edges of the lining fabric and the outer fabric are sewn together to form a down lining 20. The down lining 20 has a down filling cavity. The lining fabric and the outer fabric are connected by a first trapezoidal quilting line 30. The first trapezoidal quilting line 30 extends along a horizontal line and is arranged linearly along the vertical line to form several lines, thereby dividing the down filling cavity into several strip-shaped down cavities 21. Each first trapezoidal quilting line 30 includes a first lower horizontal line 31, a first upper diagonal line 32, and a first upper horizontal line 33 connected in a sequential loop. 3 and the first downward slant line 34; the outer fabric 10 is located on the side of the inner fabric away from the lining fabric. The outer fabric 10 is connected to the down inner lining 20 through the second trapezoidal quilting line 40. The second trapezoidal quilting line 40 extends along the horizontal line and is arranged linearly along the vertical line into several lines. The second trapezoidal quilting line 40 and the first trapezoidal quilting line 30 are staggered to divide the strip-shaped down cavity 21 into several small down cavities 22. Each second trapezoidal quilting line 40 includes a second downward horizontal line 41, a second upward slant line 42, a second upward horizontal line 43, and a second downward slant line 44 that are connected in a cyclic manner in this application. The first downward horizontal line 31, the first upward slant line 32, the first upward horizontal line 33, and the first downward slant line 34 are connected in a cyclic manner to form the geometric shape of the trapezoidal quilting line. Compared with ordinary horizontal straight quilting lines, the trapezoidal quilting line forms a stable support between the inner fabric and the lining fabric, which can effectively fix the down filling and solve the problems of easy displacement and clumping of traditional quilting lines. Furthermore, the trapezoidal quilting increases the stitch density by 30% and the stitch strength by 25% compared to traditional designs, significantly enhancing the structural stability of down jackets. In addition, the trapezoidal quilting design distributes stress more evenly on the stitches, reducing localized pressure and lowering the risk of stitch breakage by 40%.

[0016] Based on the first trapezoidal quilting pattern 30 between the lining and the outer fabric, the outer fabric 10 is further connected to the down lining 20 via a second trapezoidal quilting pattern 40 that is offset from the first trapezoidal quilting pattern 30. This ensures that the first and second trapezoidal quilting patterns 30 do not overlap but intersect, further dividing the strip-shaped down cavity 21 into several smaller down cavities 22. This allows the down to be distributed more evenly within the down lining 20 and further increases the overall support and stability of the down jacket fabric. The down lining 20, based on the shape of the garment, forms different surfaces of the down jacket, thus piecing together a complete down jacket.

[0017] The first trapezoidal quilted track 30 and the second trapezoidal quilted track 40 have the same shape. This means that the lengths of the first lower horizontal line 31 and the second lower horizontal line 41 are the same, the lengths of the first upper horizontal line 32 and the second upper horizontal line 42 are the same, the lengths of the first upper horizontal line 33 and the second upper horizontal line 43 are the same, and the lengths of the first lower horizontal line 34 and the second lower horizontal line 44 are the same. The distance between the first lower horizontal line 31 and the first upper horizontal line 33 is equal to the distance between the second lower horizontal line 41 and the second upper horizontal line 43. Using a vibration waveform analogy, this can be understood as both having the same period and the same amplitude. However, the positions of the first trapezoidal quilted track 30 and the second trapezoidal quilted track 40 are staggered to separate the filling cavity, which can be analogized to them having different initial phases. Furthermore, the second trapezoidal quilted track 40 and the first trapezoidal quilted track 30 have a height offset. The identical shape of both allows workers or equipment to quilt along the same trajectory; simply changing the starting position alters the position of the different quilting lines. The template and equipment are compatible with 2.0mm water-green epoxy board templates and 360° template carriages, solving the problem of fabric misalignment during high-speed quilting, ensuring uniform quilting spacing without knots, and increasing the production yield to 95%.

[0018] The lengths of the first lower horizontal line 31 and the second lower horizontal line 41 are the same; the lengths of the first upper diagonal line 32 and the second upper diagonal line 42 are the same; the lengths of the first upper horizontal line 33 and the second upper horizontal line 43 are the same; and the lengths of the first lower diagonal line 34 and the second lower diagonal line 44 are the same. The length of the first upper diagonal line 32 is equal to the length of the first lower diagonal line 34, allowing the first trapezoidal trajectory quilting 30 to extend horizontally. Within one quilting trajectory period of the first trapezoidal trajectory quilting 30, the first upper horizontal line 33 is located above and in front of the first lower horizontal line 31. The first lower horizontal line 31 is connected to the left side of the first upper horizontal line 33 via the first upper diagonal line 32, and the right side of the first upper horizontal line 33 is connected to the first lower horizontal line 31 of another quilting trajectory period via the first lower diagonal line 34. The second trapezoidal trajectory quilting 40 is similar.

[0019] The distance between the first lower horizontal line 31 and the first upper horizontal line 33 is equal to the distance between the second lower horizontal line 41 and the second upper horizontal line 43. This can be analogized to the first trapezoidal trajectory quilting line 30 and the second trapezoidal trajectory quilting line 40 having the same amplitude.

[0020] In the vertical direction, the first lower horizontal line 31 and the second upper horizontal line 43 are aligned, and the first upper horizontal line 33 and the second lower horizontal line 41 are aligned; the first upper diagonal line 32 and the second lower diagonal line 44 intersect, and the first lower diagonal line 34 and the second upper diagonal line 42 intersect. The second trapezoidal quilting line 40 and the first trapezoidal quilting line 30 can be staggered without intersecting. Preferably, the second trapezoidal quilting line 40 and the first trapezoidal quilting line 30 are staggered in an intersecting manner, so that the striped down cavity 21 divides into more small down cavities 22 with more variety in height and size, making the down distribution more uniform, and the intersecting quilting lines make the down jacket fabric more supportive and stable. Specifically, the intersecting forms are staggered such that the first lower horizontal line 31 and the second upper horizontal line 43 are aligned, and the first upper horizontal line 33 and the second lower horizontal line 41 are aligned. This allows the first upper diagonal line 32 and the second lower diagonal line 44 to intersect, and the first lower diagonal line 34 and the second upper diagonal line 42 to intersect, thereby forming multiple staggered small cavities 22.

[0021] The distance between each first trapezoidal trajectory quilting line 30 is equal to the distance between the first lower horizontal line 31 and the first upper horizontal line 33; the distance between each second trapezoidal trajectory quilting line 40 is equal to the distance between the second lower horizontal line 41 and the second upper horizontal line 43.

[0022] In the vertical direction, the first lower horizontal line 31 is located midway between two adjacent second upper horizontal lines 43. This arrangement allows the first upper diagonal line 32 and the second lower diagonal line 44 to intersect each other, thereby forming more small down cavities 22 and improving the support and stability of the down jacket. The gaps between the quilting lines can also be reduced to save costs.

[0023] The inclination angle of the first upward diagonal line 32 and the second upward diagonal line 42 is between 45 and 75 degrees, preferably 60 degrees. The inclination angle of the first downward diagonal line 34 and the second downward diagonal line 44 is between 285 and 315 degrees, preferably 300 degrees.

[0024] This application utilizes a trapezoidal quilting design to distribute stress more evenly on the seams, reducing localized pressure and lowering the risk of seam breakage by 40%. Warmth retention: By fixing the down distribution, warmth retention is improved by 20% (ASTM D3575 standard test).

[0025] Comfort: The trapezoidal quilting reduces the feeling of pressure on the body, improving user comfort rating by 15%.

[0026] Durability: After 50 standard wash tests, the down jacket retains 90% of its functionality.

[0027] The above are merely preferred embodiments of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are within its protection scope. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within its protection scope.
