Description

Technical Field

[0001] The invention belongs to the technical field of clothing and relates to a curved sleeve, a curved sleeve drawing method and clothing. Background Art

[0002] The upper limbs of the human body are the most active and have the largest range of motion. They move through the shoulders, elbows, wrists and other parts, thereby driving the movement of various parts of the body. Therefore, when designing the sleeves of sportswear, it is necessary to fully consider the structure of the upper limbs and their range of motion. The sleeves of ordinary clothing usually feel restrained when the human body is exercising, and the overly loose curved sleeve angle will result in the lack of beauty and fit of the clothing.

[0003] According to ergonomics, in daily activities, the natural shape of the human arm is forward-leaning, and there is a natural bend from the elbow. However, ordinary sleeves often adopt a more traditional straight-line structure, which fails to fully consider the natural bending angle and dynamic characteristics of the arm. This may cause the wearer to feel tight or restrained in the sleeves during activities, affecting the comfort of wearing. Summary of the invention

[0004] Purpose of the invention: The purpose of the present invention is to provide a curved sleeve and a method for drawing the same, so as to solve the problem that the shape of ordinary sleeves fails to fully consider the natural shape and movement patterns of human arms, resulting in the inability to fit the arm curve closely or provide sufficient support when worn. This inadaptability will affect the overall comfort and athletic performance of the wearer, and limit the range of motion of the arms in some activity scenarios.

[0005] Technical solution: A curved sleeve of the present invention is a raglan sleeve, comprising a front sleeve piece, a lower sleeve piece and a back sleeve piece, the upper ends of the front sleeve piece and the back sleeve piece extend to the position of the shoulders, the seam between the front sleeve piece and the lower sleeve piece is Z-shaped, the lower sleeve piece and the back sleeve piece are provided with a forward curvature from the cuff to the middle of the sleeve to form a curved sleeve, and a dart is provided at the upper end of the lower sleeve piece.

[0006] Furthermore, the front bending inclination angle of the curved sleeve is 8°-9°.

[0007] Furthermore, in order to solve the problem that sleeves made of general fabrics are prone to bulging or wear at the elbows after being worn for a long time, which affects the appearance of the clothing, the lower sleeve piece is made of high-elastic mesh fabric to improve the comfort of the wearer.

[0008] The present invention provides a method for drawing the curved sleeves, comprising the following steps:

[0009] S1, determine the sleeve length, sleeve width and cuff length;

[0010] S2, using the data of the sleeve length as the length and the data of the sleeve width as the width, drawing a rectangular basic structure frame line;

[0011] S3, take the width of the rectangular basic structure frame line as the reference line, take 1 / 2 and deviate 1.5 cm to draw a vertical line D1-D2, take 1 / 3 of the height of the rectangular basic structure frame line on one side and drop 1±0.5 cm to draw f1-f2, then draw a diagonal line downward from points f1 and f2, and the intersection points with the rectangular basic structure frame line are g1 and g2, so that g1-g2=1 / 2 of the cuff length;

[0012] S4, according to the size of the sleeve hole of the garment body, draw the front sleeve hole arc at f1, draw the back sleeve hole arc at f2, take point O1 at 1 / 3 of the back sleeve hole arc, set O2 1cm back from the midpoint of g1-g2, connect O1-O2, and use the line O1-O2 as the expansion line and O2 as the expansion point;

[0013] S5, draw the modeling line D1-c1-c2-O2, cut the cuffs according to the modeling line and expand and increase the amount;

[0014] S6, erasing redundant frame lines to obtain pieces A and B, wherein piece B is a lower sleeve piece;

[0015] S7, dividing the cut piece A into a front sleeve piece and a lower sleeve piece;

[0016] S8, the space between the front sleeve and the lower sleeve is expanded to increase the looseness of the sleeve elbow when it moves forward;

[0017] S9, a dart is made at the upper end of the lower sleeve piece.

[0018] Furthermore, the specific steps of expanding and increasing the amount in step S5 are: taking point c2 as the fixed rotation end point, rotating the armhole forward by α=10-12° to obtain c2-e1, and taking point c2 as the fixed rotation end point, rotating the armhole backward by β=8-10° to obtain c2-e2, and the total expansion amount on both sides is 12-15 cm.

[0019] Furthermore, the specific steps of step S7 are: take out piece A separately, make c3 at 1 / 4 of the arc f1-g1, connect it with c1 to obtain the line segment c1-c3, take the midpoint of the line segment c1-c3 as point p, take point B at 1 / 6 of the lower end of the arc f1-g1, and draw a "reverse L" shape line from point p to point B to divide piece A into piece C and piece D, wherein piece C is the front sleeve piece and piece D is the lower sleeve piece.

[0020] Furthermore, the specific steps of step S8 are: take c3-c1 as the unfolding line, take point p as the end point and unfold upwards by 2-4 cm, and the unfolding angle γ=11.5°.

[0021] Furthermore, the drawing method is to draw on a grey cloth or drawing paper, or to use electronic drawing.

[0022] Furthermore, the specific steps of step S9 are to take the midpoint of the line segment p-c2 as A1, take the midpoint of c2-e1 as A2, connect A1-A2, take A2 as the endpoint and A1 as the expansion point for expansion, the expansion amount is 2 cm, the expansion angle δ=17.5°, and a province is made, the length of the province is 6 cm.

[0023] The invention provides a garment comprising the above-mentioned curved sleeves.

[0024] Beneficial effects: Compared with the prior art, the present invention has the following significant advantages: 1. Improved wearing comfort: A dart is provided at the upper end of the lower sleeve piece, and after the dart is closed, an outward convex volume is formed, which cleverly creates a space for the elbows of the human body to move, making the sleeves more comfortable and free to wear without restricting the movement of the elbows;

[0025] 2. Ergonomics: The lower sleeve and the back sleeve are designed with a forward curvature from the cuff to the middle of the sleeve, forming a curved sleeve. This design makes the sleeve fit the natural curve of the human arm better, reducing friction and discomfort when wearing. At the same time, it also makes the sleeve look more smooth and natural;

[0026] 3. Optimize visual effects: The Z-shaped lines of the front sleeve and the lower sleeve are vertical quilting lines, which not only increase the visual layering of the sleeves, but also make the entire sleeve look slimmer under the quilting line division;

[0027] 4. Standardization and consistency: Through a fixed drawing method, it can be ensured that the sleeves produced each time are highly consistent and standardized. This helps to reduce errors and uncertainties in the production process and improve production efficiency and quality control. BRIEF DESCRIPTION OF THE DRAWINGS

[0037] The technical solution of the present invention is further described below in conjunction with the accompanying drawings.

[0038] Example 1

[0039] like Figure 1 , 2 As shown, a curved sleeve of the present embodiment is a raglan sleeve, and the curved sleeve comprises a front sleeve piece 1, a lower sleeve piece 2 and a back sleeve piece 3. The upper ends of the front sleeve piece 1 and the back sleeve piece 3 extend to the position of the shoulders, and the seam between the front sleeve piece 1 and the lower sleeve piece 2 is Z-shaped. The lower sleeve piece 2 and the back sleeve piece 3 are provided with a forward curvature from the cuff to the middle of the sleeve to form a curved sleeve, and a dart 4 is provided at the upper end of the lower sleeve piece.

[0040] In a specific embodiment, the curved sleeve structure of the curved sleeve fully considers the bending degree and shape of the arm in a natural state, ensuring that the sleeve can closely fit the arm curve and provide a comfortable wearing experience. The forward bending tilt angle is 8°-9°. From an ergonomic point of view, when the human arm is naturally drooping, the elbow joint is in a relatively straight state, and its extension angle is usually between 0° and 10°. The forward bending tilt angle a=8°-9° of the present invention is within this range, which can make the arm in a natural state reach a relatively comfortable state.

[0041] Furthermore, the fabrics of the two places on the lower sleeve pieces are made of high-elastic mesh, which has good breathability and perspiration-wicking effects after wearing. The good elasticity allows the wearer to move more freely. This structure can make the arms move more comfortably during daily wear.

[0042] The present invention provides a method for drawing a curved sleeve. The principle of the curved sleeve pattern making is to adjust the bending angle of the sleeve and the arm so that the sleeve and the sleeve elbow form a natural transition, which usually involves the matching relationship between the angles of the sleeve and the elbow. In addition, the curved sleeve pattern making method can also be adjusted according to different groups of people. But generally speaking, to make the curved sleeve, it is first necessary to determine the parameters such as the length, width and shape of the sleeve, and then draw the sleeve and body cut pieces according to these parameters.

[0043] Example 2

[0044] This embodiment takes the sleeve length of 60 cm, the sleeve width of 45 cm, and the 1 / 2 cuff of 28 cm as an example, and includes the following steps:

[0045] Step 1: Figure 3 , select the grey cloth, drawing paper or electronic drawing, and draw a rectangular basic structure frame line according to the sleeve length and sleeve width, which is 60cm long and 45cm wide;

[0046] Take the width as the reference line, take 1 / 2 and offset 1.5cm to draw a vertical line D1-D2. Take 1 / 3 on one side of the height and 1 / 3 on the other side and drop 1cm to make f1-f2 (as the frame structure of the sleeve and also the sleeve width). Then, from f1 and f2 points downward, make g1-g2 of 1 / 2 of the cuff 28cm.

[0047] Draw the corresponding armhole arc according to the size of the sleeve hole of the body. F1 is the front armhole, f2 is the back armhole, take O1 at 1 / 3 of the back armhole, set O2 1cm back from 1 / 2 of the cuff, connect O1-O2, use the line O1-O2 as the expansion line, and O2 as the subsequent expansion point;

[0048] Step 2: Figure 4 , according to the modeling line D1-c1-c2-O2, the cuffs are cut and expanded, and c2-e1 is made by rotating the sleeve forward by α=12° with point c2 as the fixed rotation end point, and c2-e2 is made by rotating the sleeve backward by β=8°. The total expansion amount on both sides is 13cm, and this expansion amount is to make the sleeves bend forward;

[0049] Step 3: Figure 5 , 6 , erase the redundant frame lines after rotation and expansion, and obtain two pieces A and B. Then take out piece A separately, draw c3 at 1 / 4 of f1-g1, connect it with c1 to obtain the line segment c1-c3, and then draw a "reverse L" modeling line from the midpoint of this line segment to point B at 1 / 6 of the lower end of f1-g1 to divide piece A into two pieces C and D;

[0050] Step 4: Figure 7 , take c3-c1 as the expansion line, point p as the end point, expand upward 3cm, and the expansion angle γ=11.5°. Here, the sleeve elbow is loosened when moving forward to improve comfort;

[0051] Step 5: Figure 8 , 9, take out piece D separately, take point A1 at the midpoint of endpoint P-c2, take point A2 at the midpoint between c2-e1, connect A1-A2, unfold with A2 as endpoint and A1 as unfolding point, the unfolding amount is 2cm, the unfolding angle δ=17.5°, make a dart, the length of the dart is 6cm, this dart is to create a space for the human elbow to move, so that the sleeve elbow has more movement.

[0052] The curved sleeves of the present invention are ergonomically designed, and the sleeves and elbows are naturally transitioned by adjusting the bending angles of the sleeves and the arms. The drawing method of the present invention ensures the consistency and accuracy of the sleeves through standardized drawing steps. Through this design, the sleeves can be made to fit the curve of the human arm more closely, improve the wearing comfort, optimize the visual effect, and enhance the fashion sense and competitiveness of the clothing.
