A down jacket hood and its manufacturing method

Abstract

The present invention discloses a down jacket hood and a manufacturing method thereof. The hood is formed by longitudinally splicing 4 to 6 arc-shaped hood pieces with gradually decreasing lengths and radii of curvature and 3 to 4 duck webs. Among the four hood pieces close to the hood brim, two adjacent hood pieces are connected by a duck web, and zippers for hiding the duck web are connected to both sides of the duck web. When the zippers are zipped up, the hood is stacked around the neck, presenting a stand-up collar shape, wrapping the neck, and improving the warmth retention performance; when the zippers are unfolded, the duck webs are unfolded, expanding the internal space of the hood and improving the wearing comfort. The zippers themselves have a certain supporting ability and can maintain the shape of the hood surrounding the neck. The zippers cooperate with the hood pieces and the duck webs, and during walking or exercising, the hood deforms less and shifts less, which can reduce the pulling of the hood on the body and prevent the body from deforming.

Description

Technical Field

[0001] The invention relates to a down jacket with hood and also to a method for manufacturing the down jacket with hood. Background Art

[0002] Hooded collar / hooded collar is a collar style that also has the function of a hat. Its structure is essentially a combination of a hat body and a folded collar, but it has a different structure from a folded collar. It can be used as a decoration and can keep warm and block the wind.

[0003] When used as a collar, the aesthetics and comfort of stacking around the neck need to be considered. When used as a hat, there needs to be enough enclosure space to completely wrap the head. However, when a hooded collar satisfies one of the functions, it will inevitably limit another function. For example, when the volume of the hat is enlarged, the weight of the hat body will increase. When it is idle and stacked, it is easy to slide to the back, unable to enclose / wrap the neck, which reduces the warmth retention performance of the clothes. At the same time, the hat body will pull the clothes connected to the hat body backwards, causing the clothes to deform. When the collar shape is satisfied, the hat body will be too small, the space inside the hat is not large enough, and it is not comfortable and beautiful when worn on the head. The invention patent with publication number CN 111787822 A discloses a storable hood for clothing, a closable slit is set along the joint between the collar on the clothes and the main body of the clothes, and the hood connected to the main body of the clothes can be folded, rolled up or otherwise stuffed and stored in a pocket or groove. This solution is suitable for hooded jackets with a particularly thin hood body, which cannot take into account the protective function of the hood, and cannot provide comfort when the hood body is stored. The utility model patent with publication number CN 219515342 U discloses a hooded down jacket, which adds a connecting piece to the brim of the hood to expand the volume of the hood, and zippers are sewn on both sides of the connecting piece. When the zipper is closed, the connecting piece is hidden / stored. This solution solves the problem of the hood volume, but still cannot provide the effect of neck comfort and aesthetics. Summary of the invention

[0004] Purpose of the invention: The purpose of the present invention is to provide a down jacket hood that has both usable space and neck wrapping comfort; another purpose of the present invention is to provide a method for manufacturing a down jacket hood.

[0005] Technical solution: The down jacket hood described in the present invention is characterized in that the hood is formed by longitudinally splicing 4 to 6 arc-shaped hood pieces with successively decreasing lengths and curvature radii and 3 to 4 duck paws, and among the four hood pieces close to the brim of the hood, two adjacent hood pieces are connected by duck paws, and zippers for hiding the duck paws are connected on both sides of the duck paws.

[0006] When the zipper is zipped up, the hood is stacked around the neck, presenting a standing collar shape, increasing the wrapping of the neck and improving the warmth retention performance; when the zipper is unzipped, the duck feet unfold, expanding the internal space of the hood and improving the wearing comfort. The zipper itself has a certain supporting ability to maintain the shape of the hood surrounding the neck. The zipper cooperates with the cap piece and the duck feet. During walking or exercise, the hood has less deformation and displacement, which can reduce the pulling of the hood on the body of the clothes and prevent the deformation of the body of the clothes.

[0007] A manufacturing method of a down jacket hood according to the present invention includes the following steps:

[0008] (1) Take the outer cap side template ADH, intercept point I on the curve 4 - 5 cm to the right of point D, intercept point J on the curve 5.5 - 6.5 cm below point I, make the cap lining reference line IJ with reference to the middle cap curve DH, and measure the length of IJ; take the midpoint of the middle cap curve DH, take point R at 3.8 - 4.5 cm to the right of the midpoint, take points Q and T respectively to the left of point R and 9 - 12 cm to the left of the brim endpoint H, and finally take the midpoint S of the curve RT as the upper mouth dividing point of the cap; take M, N, O, P on the curve AD as the lower mouth dividing points of the cap, the lengths of the line segments DM > MN = NO = OP = PA, connect the corresponding dividing points with smooth curves QM, RN, SO, TP, and divide along the curve to obtain the divided cap piece side sample;

[0009] (2) Fix the brim cap piece side sample APTH, take M, N, O, P as the centers of circles, and rotate the rear divided cap piece side sample counterclockwise in turn so that it partially overlaps with the front divided cap piece side sample, and then reconnect the rear cap piece side sample QDM and the top of the brim cap piece side sample APTH with a smooth curve to form an indented middle cap curve DH. The difference between the indented middle cap curve DH and the cap lining curve IJ is 3 - 6 cm. Cut off the part of the front end of the rear cap piece side sample that overlaps with the front cap piece side sample and the part outside the indented middle cap curve DH to obtain the indented cap piece side sample;

[0010] (3) Place two identical indented cap piece side samples symmetrically with the tangent line of the top arc of the indented cap piece side sample as the symmetry line and connect them with a smooth curve to obtain the cap piece template;

[0011] (4) Spread out the brim and the three cap piece templates close to the brim in turn, intercept 1 - 2 cm at both ends of the cap piece template as the zipper stop points, and measure the stitching length of the two zipper stop points; make the duck foot template according to the adjacent two cap piece templates. The length of the upper arc of the duck foot piece is greater than the bottom stitching length of the upper cap piece, and the length of the lower arc is greater than the top stitching length of the lower cap piece;

[0012] (5) Cut the cut pieces according to the cap piece template and the duck foot template, splice the first four cap piece cut pieces with the zipper in turn, and add the duck foot cut pieces connecting the adjacent two cap pieces inside the zipper at the same time. Finally, stitch the rear cap piece to obtain the outer cap, and splice the outer cap and the cap lining to obtain the hood.

[0013] Modify the normal two-piece hood size, shorten the length in the middle of the hood, use the duck's foot to make up for the longitudinal length of the hood body, and use the zipper to gather or unfold the duck's foot.

[0014] Preferably, in the step (1), the curves QM, RN, SO, and TP are bent towards the back of the hood. After segmentation, the front ends of the curves QR, RS, ST, and TH are respectively shortened by 3.5 - 4.5 cm. If the outer hood is reduced too much, when it is gathered, the space for accommodating the inner hood is insufficient, affecting the retraction and deployment of the inner hood, which will affect the comfort and also the appearance.

[0015] Preferably, in the step (4), the radius of curvature of the duck's foot shaped piece is between the radii of curvature of the adjacent two hood piece templates. The length of the upper arc of the duck's foot shaped piece exceeds the bottom sewing length of the front hood piece by 0.5 - 1.5 cm, and the length of the lower arc exceeds the top sewing length of the rear hood piece by 0.5 - 1.5 cm.

[0016] Preferably, in the step (5), it further includes adding a sewing net line connecting the outer hood and the inner hood between the outer hood and the inner hood.

[0017] Preferably, in the step (5), a heat-insulating material is filled between the inner hood and the outer hood. To increase the warmth retention and windproof performance of the hood, the heat-insulating material can be one or a mixture of down, cotton, or artificial fiber.

[0018] Preferably, in the step (5), a zipper or a buckle for connecting with the body is sewn at the lower opening of the hood with an inner hood. Make the hood and the body detachably connected.

[0019] Preferably, the steps for making the inner hood are as follows:

[0020] (6) Make a template for the side piece of the inner hood along the curve IJ of the inner hood;

[0021] (7) Draw an angular line DK of the curve DC through point D, make the included angle between the two lines greater than 90°, DK = IJ, draw a perpendicular line KL to DK through point K, make KL = HJ, connect LI, obtain the side sample of the top piece of the inner hood, symmetrically place two side samples of the top piece of the inner hood along the length direction and smoothly connect them with a curve to obtain the template for the top piece of the inner hood;

[0022] (8) Cut the pieces according to the template for the side piece of the inner hood and the template for the top piece of the inner hood, splice the cut pieces of the top piece and the side piece of the inner hood to obtain the inner hood.

[0023] Preferably, in the step (7), the included angle between the curve DC and the angular line DK is 90.2 - 92°.

[0024] Preferably, the method for making the side template ADH of the outer hood is as follows:

[0025] S1: Measure the length of the front neckline and the back neckline of the garment body. Draw a first horizontal line and a first angular line AC through the front neck point A of the garment body, such that the included angle between the two lines is 15 - 19°, and AC = the length of the front neckline; draw a second horizontal line and a second angular line CD through point C, such that the included angle between the two lines is 2 - 5°, and CD = the length of the back neckline. Draw the lower edge curve AD of the cap according to the broken line ACD.

[0026] S2: Draw a perpendicular line CF through point C, and the perpendicular line CF = the height of the cap. Draw a first parallel line and a second parallel line of the perpendicular line CF through points A and D respectively. The second parallel line intersects the first horizontal line at point E; draw a perpendicular line to CF through point F, which intersects the first parallel line and the second parallel line at points H and G respectively. The area enclosed by AEGH forms the reference line of the cap body. Taking point A as the origin, rotate the reference line of the cap body clockwise by 5 - 9° to form the forward tilt amount of the cap body. Draw a curve DC angular line DK through point D, such that the included angle between the two lines is greater than 90°. Draw the middle curve DH of the cap according to the line DK, point D, F, and H to obtain the outer cap side template ADH.

[0027] Preferably, in the step S1, the included angle between the first horizontal line and the first angular line AC is 16 - 18°, and the included angle between the second horizontal line and the second angular line CD is 2 - 4°; in the step S2, when drawing the front cap edge curve according to AH and forming the forward tilt amount of the cap body, rotate the reference line of the cap body clockwise by 6 - 8°.

[0028] Beneficial effects: Compared with the prior art, the present invention has the following remarkable advantages: 1. It combines usage space and comfort: When the zipper is unfolded, the duck web compensates for the length of the outer cap, enabling the hooded garment to have sufficient usage space. When the zipper is closed, it defines the shape of the cap body, allowing it to be placed around the neck, combining comfort and warmth retention performance; 2. It is not prone to deformation and displacement: When closed, it has a specific shape, increasing the support strength and having little impact on the garment body. Description of the Drawings

[0039] The technical solution of the present invention is further described below in conjunction with the accompanying drawings.

[0040] like Figure 1 and 2 The figure shows the structure of the down jacket hooded jacket made according to the method of the present invention when unfolded and folded. The hooded jacket is formed by longitudinally splicing 4 to 6 arc-shaped hat pieces 1 and duck feet 2 with decreasing lengths and curvature radii. The four hat pieces close to the brim are connected by duck feet 2 between two adjacent hat pieces 1, and a zipper 3 is installed. When the zipper 3 is closed, the duck feet 2 are folded and hidden behind the zipper, and the longitudinal length of the hat body is reduced. When the zipper 3 is unfolded, the duck feet 2 are unfolded, the longitudinal length of the hat body is increased, and the wearable space is increased.

[0041] Figures 3 to 10 Schematic diagram of the hood manufacturing process of the present invention, as shown in Figure 3 As shown, draw a horizontal line AE and an angle line AC through point A of the front neck of the garment body, the length of AC = the length of the front collar AB, ∠CAE = 15-19°, for example, 17°, draw a vertical line CF through point C, the length of CF is equal to the height of the hat, through point C, lift up 2-5°, for example, about 3°, draw a line CD, the length of CD = the length of the back collar, forming the ACD collar reference line; draw parallel lines to CF through points A and D respectively, and the intersection point with the horizontal line AE is E, draw a vertical line to CF through point F, and get the intersection points H and G, forming the hat body reference line AEGH, AEGH is a rectangle.

[0042] like Figure 4 , take the front neck point A of the rectangle AEGH as the origin, rotate forward 5 to 9°, for example 6° or 8°, to give a forward tilt of the hat, and draw the bottom curve of the hat based on the ACD reference line.

[0043] like Figure 5 , draw the angle line DK of the DC curve through point D, ∠KDC is slightly larger than 90 (90.2~92°), based on the angle line DK, draw the cap center curve through points D, F and H, and draw the front cap mouth curve with reference to line AH.

[0044] Take point I on curve AD. Point I is 4 - 5 cm away from point D, for example, 4.5 cm. Take point J on curve AH. Point J is 5.5 - 6.5 cm away from point H, for example, 6 cm. Draw a similar curve IJ with reference to DH to form the side template AIJ of the inner cap, and measure the length of IJ. The length of DK is equal to the length of curve IJ. Draw a perpendicular line KL to DK through point K. The length of KL = curve HJ. Connect LI to form the side sample DKLI of the top piece of the inner cap. Place two side samples of the top piece of the inner cap symmetrically along the length direction and connect them with a smooth curve to obtain the template of the top piece of the inner cap.

[0045] As Figure 6 , extract the outer cap side template ADH. Combining the effect of the collar - hugging when the hat is down and the variable functions when it is lifted, divide the outer cap side sample. Specifically: Take the mid - point of curve DH. Take point R at a distance of d = 3.8 - 4.5 cm to the right of the mid - point, for example, 4.2 cm. Take points Q and T respectively at a distance of 9 - 12 cm to the left of point R and 9 - 12 cm to the left of the brim end point H, for example, 10 cm. Finally, take the mid - point S of curve RT. The obtained Q, R, S, T are the dividing points of the upper mouth of the cap; Take M, N, O, P on curve AD such that line segment DM > MN = NO = OP = PA as the dividing points of the lower mouth of the cap. Connect the corresponding dividing points with smooth curves QM, RN, SO, TP to obtain four structure lines PT / OS / NR / MQ. Divide along the structure lines to obtain the divided cap pieces.

[0046] As Figure 7 As shown, process the divided cap pieces to shorten the middle part of the cap. Specifically: Taking M, N, O, P as the origin points, rotate the divided cap pieces behind the brim cap piece counter - clockwise in sequence so that the divided cap pieces behind partially overlap with the divided cap pieces in front. The overlapping arc length of the front end of the divided cap piece behind and the front divided cap piece is about 3.5 - 4.5 cm, for example, 3.5 cm. Re - connect the top of the rear cap piece QDM and the brim cap piece APTH with a smooth curve to form the reduced middle curve DH of the cap. The difference between the length of the reduced middle curve DH of the cap and the length of the inner cap curve IJ is 3 - 6 cm. As Figure 8 As shown, cut off the overlapping part of the front side of the rear divided cap piece and the front divided cap piece, and the part outside the reduced middle curve DH to obtain the reduced outer cap side template ADH.

[0047] As Figure 9 and Figure 10 As shown, taking the tangent of the top arc of the indented cap piece side sample as the symmetry line, place two identical indented divided cap pieces symmetrically and connect the two indented divided cap pieces with a smooth curve to obtain the cap piece template;

[0048] As Figure 10As shown, spread out the brim and three pieces of cap panels near the brim in sequence, a total of four cap panel templates. Cut off 1 - 2 cm at both ends of each cap panel template as the stop points for the zipper seam, and measure the stitching length between the two stop points for the zipper seam; make a duck web template according to the stitching line between adjacent cap panel templates. The length of the upper arc of the duck web piece is greater than the bottom stitching line length of the upper cap panel, and the length of the lower arc is greater than the top stitching line length of the lower cap panel; the radius of curvature of the duck web piece is between the radii of curvature of adjacent cap panel templates. The length of the upper arc of the duck web piece exceeds the bottom stitching length of the front cap panel by 0.5 - 1.5 cm, and the length of the lower arc exceeds the top stitching length of the rear cap panel by 0.5 - 1.5 cm.

[0049] As Figure 9 and Figure 10 shown, cut out the pieces according to the cap panel template and the duck web template. Approximately along PTP′ / OSO′ / NRN′, sequentially splice the first four cap panel pieces with a zipper, and at the same time add duck web pieces connecting adjacent cap panel pieces inside the zipper. Sew the rear cap panel QDM to obtain the outer cap of the hooded cap. Cut out the pieces according to the inner cap side panel template and the inner cap top panel template, splice the inner cap top panel and side panel pieces to obtain the inner cap, and splice the outer cap and the inner cap to obtain the hooded cap with an inner cap.

[0050] When the zipper is closed, in order to make it more convenient and aesthetically pleasing to store the inner cap inside the outer cap, a horizontal and / or stitched netting can be added between the outer cap and the inner cap. A thermal insulation material can be added between the outer cap and the inner cap to improve the support strength and warmth retention performance of the cap body. A zipper or a buckle can be sewn at the lower opening of the hat to make the hood detachable from the body.
