Description

Technical Field

[0001] This invention relates to the field of clothing design technology, and in particular to a shirt suitable for billiards sports, as well as its pattern making method and manufacturing method. Background Technology

[0002] Billiards, as an indoor sport that demands extremely high precision and stability, requires players to frequently perform a series of complex and continuous movements during a match, including bending over, aiming, cueing, and striking the ball. These movements not only involve large swings of the upper limbs and flexible rotation of the shoulders, but also require the body to maintain specific postures for extended periods. Therefore, the comfort, flexibility, and functionality of billiards apparel, especially shirts, are particularly important.

[0003] A billiard shirt consists of sleeves, collar, front, and back panels. Existing billiard shirts often follow the design and tailoring of ordinary business shirts, failing to fully consider the specific needs of billiards. For example, billiard players frequently raise their arms to strike the ball, but traditional shirts have a fixed shoulder angle and insufficient armhole depth, causing a pulling sensation at the shoulder-arm connection, affecting the smoothness of the cue stroke. This is because an overly narrow armhole and improperly tailored cuff can easily create a tight feeling when the arm is raised, restricting the range of motion of the shoulder and arm; it also easily leads to poor breathability in the underarm area, causing sweat to accumulate and affecting comfort. The sleeve width is usually a uniform design, lacking sufficient ease at the sleeve width and elbow, but the elbow needs to bend significantly when striking the ball, making the arm feel restricted when bending and extending. A cuff design that is too tight or lacks elasticity may affect wrist flexibility, thus affecting the stability of the shot. If the sleeve width is too wide, it appears bulky and affects aesthetics.

[0004] Therefore, the design of traditional billiard shirts in areas such as armholes, sleeve bases, sleeve widths, elbows, and cuffs often fails to fully meet the movement needs of various parts of the body during billiards, easily causing the wearer to feel restricted and uncomfortable during exercise, and even affecting performance. In response to the special needs of billiards, it is necessary to optimize the design of key parts of the shirt. Summary of the Invention

[0005] The purpose of this invention is to overcome the problem that existing billiard shirts cannot fully meet the activity needs of various parts of the body during billiards, which can easily lead to the wearer feeling restricted and uncomfortable during exercise, and even affect performance.

[0023] As a preferred embodiment of the present invention, the pattern-making method further includes obtaining the chest circumference, waist circumference, and shoulder width of the billiards shirt based on conventional shirt size data. More specifically, the chest circumference, waist circumference, and shoulder width of the billiards shirt are the same as those in the conventional shirt size data.

[0024] A second aspect of the present invention also provides a billiards shirt, which is designed using the pattern-making method described above for a billiards shirt.

[0025] As a preferred embodiment of the present invention, compared with conventional shirt models, the armhole depth of the sleeve piece of the shirt is increased by 0.4~0.6cm, the sleeve width is increased by 0.8~1.2cm, the elbow is increased by 0.6~1cm, the undersleeve seam is lengthened by 2.8~3.5cm, the shoulder slope angle is reduced by 0.4~0.6°, and the sleeve cap height is reduced by 1~3cm.

[0026] As a more preferred embodiment of the present invention, compared with conventional shirt models, the collar length of the shirt is increased by 0.8~1.2cm, the sleeve length is increased by 1.8~2.4cm, the cuff is reduced by 0.8~1.2cm, and the back center length is increased by 2~3cm.

[0030] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. This invention provides a pattern-making method suitable for billiards shirts. Based on a conventional shirt pattern, the method calculates the armhole depth, sleeve width, elbow, undersleeve seam, and shoulder slope angle of the billiards shirt according to conventional shirt model data. The calculation results show that the shoulder slope angle of the billiards shirt is reduced, the armhole depth is increased, and the sleeve width, elbow, and undersleeve seam are all enlarged. The reduction in the shoulder slope angle allows for greater freedom of shoulder movement and reduces the feeling of restriction during exercise. The increased armhole depth, combined with the reduced shoulder slope angle, further optimizes the arm's range of motion and prevents the shirt from shifting during exercise. The lengthened undersleeve prevents the shirt sleeve from being too tight when the arm is raised, ensuring smooth movement. The increased sleeve width and elbow size provide ample space for the extension and flexion of arm muscles, avoiding excessive pressure on the muscles during exercise.

[0031] 2. Based on the conventional shirt design, the shirt of the present invention optimizes the design of key parts of the shirt to meet the special needs of billiards, improves the wearing experience of players, significantly reduces the feeling of restriction during exercise, and helps players maintain their best competitive state.

Detailed Implementation

[0033] The present invention will now be described in further detail with reference to specific embodiments. However, this should not be construed as limiting the scope of the present invention to the following embodiments; all technologies implemented based on the content of the present invention fall within the scope of the present invention.

[0034] This disclosure provides a pattern-making method suitable for billiards shirts, including the following steps: Based on the standard shirt pattern, obtain standard shirt size data; The armhole depth, sleeve width, elbow, and underarm seam of a billiards shirt are calculated based on standard shirt size data using the following formulas:

[0035]

[0036]

[0037]

[0038] Where X1 is the armhole depth of the billiards shirt, X is the armhole depth in the standard shirt size data, and x ranges from 0.015 to 0.03; S1 is the sleeve width of the billiards shirt, S is the sleeve width in the standard shirt size data, and s ranges from 0.015 to 0.03; Q1 is the elbow of the billiards shirt, Q is the elbow in the standard shirt size data, and q ranges from 0.01 to 0.02; P1 is the underarm seam of the billiards shirt, P is the underarm seam in the standard shirt size data, and p ranges from 0.05 to 0.07. The shoulder slope angle is calculated based on standard shirt size data. The formula is as follows:

[0039] Where α1 is the shoulder slope angle of the billiards shirt, α is the shoulder slope angle in the standard shirt model data, and β takes a value of 0.3~0.8°.

[0040] In the aforementioned technical solution, based on a standard shirt pattern, the armhole depth, sleeve width, elbow, underarm seam, and shoulder slope angle of the billiards shirt are calculated according to standard shirt size data. The calculations show that the shoulder slope angle is reduced, the armhole depth is increased, and the sleeve width, elbow, and underarm seam are all enlarged. The reduced shoulder slope angle allows for greater shoulder freedom of movement, reducing the feeling of restriction during exercise. The increased armhole depth, combined with the reduced shoulder slope angle, further optimizes arm movement space and prevents the shirt from shifting during exercise. The extended underarm prevents the shirt sleeve from being too tight when the arm is raised, ensuring smooth movement. The increased sleeve width and elbow dimensions provide ample space for arm muscle extension and flexion, avoiding excessive pressure on muscles during exercise. Following the above method, the dimensions of different parts of the shirt are designed for different shirt sizes, balancing fit, comfort, and functionality to ensure players can swing freely during competition, maintain a professional image, and exude elegance.

[0041] It should be noted that in this embodiment, the length measured diagonally from the armhole deep shoulder sleeve point to the bottom edge of the sleeve, the sleeve width is the length measured horizontally from the bottom edge of the sleeve, the sleeve elbow is the length measured horizontally at 1 / 2 of the sleeve length, the sleeve bottom seam refers to the longitudinal seam on the inside of the sleeve (near the armpit), the shoulder slope angle is the angle of inclination of the shoulder from the neck to the shoulder end, the sleeve cap refers to the curved part of the sleeve, that is, the part where the sleeve connects to the body of the garment, the sleeve cap height refers to the vertical distance from the highest point of the top arc of the shirt sleeve to the sleeve width line (the horizontal line at the widest part of the sleeve); the collar length is the straightness from the center button to 0.2cm inside the buttonhole, the sleeve length is the length from the shoulder sleeve point to the cuff, the cuff is the length from 0.2cm inside the buttonhole to the center button, the back center length is the length from the back center collar to the hem, the chest circumference is the length measured horizontally 2cm below the bottom edge of the sleeve, the waist circumference is the length measured horizontally at the waist, and the shoulder width is the width measured horizontally from the shoulder point.

[0042] The conventional shirt pattern used in the pattern-making method can be a regular business shirt pattern or an existing billiards shirt pattern. The billiards shirt of this invention is an improvement on the regular business shirt or existing billiards shirt pattern, wherein the conventional shirt pattern can be based on the national 5.4 standard size or corporate shirt size. Based on the conventional shirt pattern, the size data of different conventional shirt models are obtained, such as chest circumference, shoulder width, armhole depth, sleeve width, elbow, etc.

[0043] In some embodiments, x takes the value of 0.02~0.024, s takes the value of 0.02~0.025, q takes the value of 0.011~0.016, and p takes the value of 0.06~0.07. In the above technical solution, the armhole depth is increased. The increased armhole depth, combined with the reduced shoulder slope, can further optimize the range of motion between the shoulder and arm. When the arm makes large-scale raising and swinging movements, the shirt sleeve will not be too tight or constricting, preventing the clothing from shifting and ensuring the wearer's stability and comfort during exercise. The sleeve width and elbow area are increased because when playing billiards, the arm needs to be constantly bent and extended, especially the muscles in the elbow and forearm are more active. Increasing the sleeve width and elbow area provides ample space for the normal extension and contraction of arm muscles, avoiding excessive compression of muscles by the clothing, reducing discomfort during exercise, and improving wearing comfort and flexibility of movement. The lengthened undersleeve seam effectively prevents the undersleeve from being too tight when the arm is raised to hit the ball, allowing the arm to move more freely up and down without being restricted by the clothing and thus preventing exposure problems caused by an overly short undersleeve seam.

[0044] In some embodiments, β is taken as 0.4~0.6°. In the above technical solution, the calculated shoulder slope angle of the billiards shirt is reduced by 0.4~0.6°, making the shoulders appear flatter. During billiards, shoulder movements are frequent, such as arm swinging and hitting the ball. Reducing the shoulder slope allows the shoulder muscles to relax more during exercise, reducing fatigue caused by clothing constraints, and also facilitates natural arm swing, improving flexibility.

[0045] In some embodiments, the pattern-making method further includes calculating the sleeve cap height of the billiard shirt, wherein the formula for calculating the sleeve cap height is:

[0046] Where Y1 is the sleeve cap height of the billiards shirt, Y is the sleeve cap height in the data of regular shirt models, and y takes a value of 1~3cm.

[0047] In some embodiments, the pattern-making method further includes calculating the collar length of a billiards shirt collar, wherein the formula for calculating the collar length is:

[0048] Where B1 is the collar length of the billiards shirt, B is the collar length in the regular shirt size data, and b ranges from 0.03 to 0.045.

[0049] Most existing billiard shirts have standard collar sizes. However, billiard players need to maintain a forward-leaning posture for extended periods when bending over to hit the ball. A collar that is too tight restricts neck movement, affecting the player's vision and head rotation, as well as breathing and concentration. The technical solutions described above involve increasing the collar length compared to the standard version. When playing billiards, the head needs to rotate frequently, and the body also involves forward and backward leaning movements. Increasing the collar size allows the neck to move freely, enabling the wearer to breathe easily and improving comfort.

[0050] More preferably, The value ranges from 0.035 to 0.04.

[0051] In some embodiments, the pattern-making method further includes calculating the sleeve length based on standard shirt size data, using the following formula:

[0052] Where M1 is the sleeve length of the billiards shirt, M is the sleeve length in the regular shirt model data, and m ranges from 0.025 to 0.04.

[0053] More preferably, The value ranges from 0.03 to 0.035.

[0054] In some embodiments, the pattern-making method further includes calculating the cuff based on standard shirt size data, using the following formula:

[0055] Where D1 is the cuff of the billiards shirt, D is the cuff in the standard shirt model data, and d takes a value of 0.03~0.06. More preferably, d takes a value of 0.04~0.05.

[0056] In some embodiments, the pattern-making method further includes calculating the back center length of the back piece based on conventional shirt size data, using the following formula:

[0057] Where N1 is the back center length of the billiards shirt, N is the back center length in the regular shirt model data, and n takes a value of 0.028~0.045.

[0058] More preferably, n takes the value of 0.03 to 0.04.

[0059] In some embodiments, the pattern-making method further includes obtaining the chest circumference, waist circumference, and shoulder width of the billiards shirt based on conventional shirt size data. More specifically, the chest circumference, waist circumference, and shoulder width of the billiards shirt are the same as those in the conventional shirt size data.

[0060] This disclosure also provides a shirt suitable for billiards, which is designed using the pattern-making method described above.

[0061] In some embodiments, compared to a regular shirt size, the armhole depth of the shirt sleeve is increased by 0.4 to 0.6 cm, the sleeve width is increased by 0.8 to 1.2 cm, the elbow is increased by 0.6 to 1 cm, the undersleeve seam is lengthened by 2.8 to 3.5 cm, the shoulder slope angle is reduced by 0.4 to 0.6°, and the sleeve cap height is reduced by 1 to 3 cm.

[0062] In some embodiments, compared to a regular shirt size, the collar length is increased by 0.8 to 1.2 cm, the sleeve length is increased by 1.8 to 2.4 cm, the cuff length is decreased by 0.8 to 1.2 cm, and the back center length is increased by 2 to 3 cm.

[0063] In some embodiments, the shirt cuffs are horseshoe-shaped, with the upper part being larger than the lower part, to fit the human body structure.

[0064] In the above-mentioned technical solution, the human wrist has a certain degree of curvature in a natural relaxed state. However, traditional cuff designs often do not conform to this physiological structure. When playing billiards, the wrist needs to rotate and bend frequently to adjust the angle of the cue stick. The cuff of this invention adopts a horseshoe shape, with the upper part being larger than the lower part, which conforms to the physiological structure of the human wrist. It can closely fit the physiological curve of the wrist, ensuring comfort while facilitating flexible wrist rotation during actions such as hitting the ball. It will not affect athletic performance due to the cuff being too tight or too loose, and it can effectively prevent the shirt cuff from slipping down, ensuring the stability of the cuff position.

[0065] In some embodiments, the shirt fabric comprises 63-70% polyester fiber, 22-30% modal fiber, and 2-10% spandex. Most existing shirt fabrics are made of pure cotton or polyester-cotton blends, which, while absorbent, lack elastic fibers and are difficult to adapt to multi-angle limb movement. The shirt of this invention uses top-grade modal fabric with specially designed skin-friendly heat-pressed labels, providing a soft, moisturizing, and pressure-free comfort suitable for sensitive skin. It also incorporates high-quality wrinkle-resistant polyester and spandex fibers, preventing limpness and deformation, keeping it looking new at all times, and allowing for free movement.

[0066] This disclosure also provides a method for manufacturing a shirt suitable for billiards, including the following steps: S1: Pattern making and cutting out the following pieces: front piece, back piece, sleeves, and collar; S2: Sequentially sew the front and back plackets, make pockets, attach the collar, attach the sleeves, sew the side seams, sew the undersleeve seams and hem seams, and sew the sleeve vents. The maximum ease of the sleeve during the sleeve attachment process is 0.7cm. S3: Wash, dry, iron, and shape to obtain a billiards shirt.

[0067] The present disclosure will be further described below through specific embodiments. However, the following embodiments are only used to illustrate the present disclosure, and the scope of the present disclosure is not limited thereto.

[0068] Example 1 This embodiment provides a shirt suitable for billiards, such as... Figure 1 , Figure 2 The shirt includes a front panel 21, a back panel 22, sleeves 23, and a collar 24. It is a men's shirt, designed using a pattern-making method suitable for billiards shirts. Calculations were performed, with the following values: armhole depth x = 0.022, sleeve width s = 0.023, elbow q = 0.014, undersleeve seam p = 0.066, shoulder slope angle β = 0.5°, and collar length... The value is 0.036, used to calculate the sleeve length. The value is 0.032, the cuff length d is calculated to be 0.042, and the calculated mid-length n is 0.033. The regular shirt in this embodiment is a standard size 40. A comparison of different parts of the regular shirt 1 and the billiards shirt 2 after design is shown below. Figure 3 , Figure 4 , Figure 5 , Figure 6 The sizes of shirts suitable for billiards are shown in Table 1 below.

[0069] Table 1 shows the sizes of billiard shirts suitable for Example 1.

[0070] The armhole depth is 22.5cm, sleeve width is 42cm, elbow width is 35.7cm, undersleeve seam is 51cm, sleeve length is 63.5cm, and sleeve cap height is reduced by 2cm. The 22.5cm armhole depth is on the narrower side for a shirt size. Combined with the 42cm sleeve width, this design is relatively loose, suitable for casual or sporty shirts. The 35.7cm elbow width and 22.5cm undersleeve seam length indicate a looser hem, allowing for greater freedom of movement and comfort during arm movements. Furthermore, the combination of the 22.5cm armhole depth and 42cm sleeve width increases the armhole's spaciousness, expanding the fit between the sleeve cap and armhole, thus providing ample room for sleeve installation.

[0071] With increased sleeve width, the sleeve cap height can be appropriately lowered to ensure sleeve looseness and wearing comfort. This armhole structure was designed with the coordination between various elements such as sleeve cap, sleeve width, and armhole in mind. By adjusting the size proportions of each part, the sleeve can better adapt to the new armhole structure, thus achieving a smooth installation.

[0072] To make a billiards shirt, follow the dimensions in Table 1 above. The manufacturing method includes the following steps: S1: Pattern making and cutting out the front, back, sleeves, and collar pieces; according to the pattern, use cutting equipment to cut the fabric along the outline of the pattern. When cutting, the edges should be neat and smooth, without any rough edges or gaps, and the fabric should be kept from deforming. The cut pieces should be sorted and arranged according to the structure and parts of the shirt, such as the front, back, sleeves, collar, and pockets.

[0073] The shirt uses a fabric composition of 68.0% polyester fiber + 27.7% modal fiber + 4.3% spandex, with a yarn density of T / M55S*T / M55S+30DSP 160*108. The fabric passed tests for water resistance, tear resistance, water absorption, shrinkage, and abrasion resistance. Before garment production, the fabric is inspected carefully for holes, stains, uneven coloring, or uneven weave, just like checking for defects in clothing. Simultaneously, the shrinkage rate and colorfastness are checked to ensure fabric quality. The fabric is then pre-shrinked in a professional pre-shrinking device to reduce shrinkage before washing, preventing deformation and shrinkage during the final washing process. Before cutting, lay the prepared fabric on the cutting table. Determine the number of layers based on the cutting plan and layout diagram. Generally, the cutting table can handle several layers; for stiff fabrics, more layers can be laid, but no more than 100 layers are allowed to ensure cutting speed and accuracy. Arrange the cutting pattern on the cutting table according to the shirt's style, size, and the fabric's width and characteristics. Ensure that the shape and size of each cut component meet design requirements while making full use of the fabric. During the layout process, pay attention to the fabric's directionality; for example, for striped or checkered fabrics, ensure the stripe direction matches the design.

[0074] S2: Sequentially sew the front and back plackets, make pockets, attach the collar, attach the sleeves, sew the side seams, sew the undersleeve seams and hem seams, and sew the sleeve vents. The maximum ease of the sleeve during the sleeve attachment process is 0.7cm.

[0075] Stitching the placket and lining: First, iron a layer of fusible interfacing onto the reverse side of the placket. Then, fold the placket over, iron the raw edges flat, and stitch a line along the edge to form a visible edge. The lining is treated in the same way. During the process, attention should be paid to the size and position of the lining to ensure that it meets the design requirements of the shirt and that the placket and lining are aligned and flat.

[0076] Making pockets: Fold the pocket opening over and iron it flat. Sew along the edge to form a visible seam. Then, sew the pocket onto the front of the shirt in the corresponding position. When sewing the pocket, make sure that the position of the pocket is accurate and flat, without any crookedness. At the same time, make sure that the pocket is a certain distance from the edge of the front piece, generally about 1 to 2 centimeters, so that the pocket looks nice.

[0077] Attaching the collar: First, cut out the collar facing, collar lining, and collar interfacing, then assemble them. Attach the collar interfacing to the wrong side of the collar facing. Next, place the collar facing and collar lining right sides together and sew along the edges, leaving an opening for the collar. After turning it inside out, iron the collar flat and then sew a line along the edge of the collar to form a visible seam. Attach the collar to the shirt collar opening, ensuring that the collar size matches the collar opening. The collar should be able to fold freely, neither too tight nor too loose.

[0078] Sleeve Assembly: Place the front and back pieces of the garment right sides together and sew them together along the side seams to form the garment body. Then, place the right sides of the sleeve pieces together with the right sides of the garment body, aligning them with the marked lines. The undersleeve seam should be aligned with the hem seam, leaving a seam allowance of about 1 cm. When attaching the sleeves, ensure that the maximum sleeve ease is 0.7 cm. The sleeve ease of a normal shirt sleeve is 1.2 cm. Since the sleeve width in this invention is relatively large, the sleeve cap needs to be properly gathered when sewing the sleeve cap and armhole so that the sleeve cap can better adapt to the shape of the armhole. At the same time, the maximum sleeve ease must be controlled at 0.7 cm, but wrinkles or pleats must be avoided. It is also necessary to ensure that the front and back are consistent in tightness. Through gathering and ease adjustment, the sleeve and garment body can achieve a smooth and flat effect after sewing, avoiding wrinkles or tightness. This ensures that the sleeves look natural and beautiful after being attached, and allow for free movement.

[0079] Sewing the side seams: Place the front and back pieces of the garment right sides together and sew them together along the side seam line. During the sewing process, the seam should be straight and firm, the upper and lower layers should be flat and smooth, and the seam allowance width should be consistent, controlling the seam allowance width to be about 1 cm. After sewing, overlock the seam allowance to prevent the thread from coming undone.

[0080] Sew the hem and sleeve seams together: Start sewing the hem and sleeve seams together from the bottom hem upwards, making sure the cross seams at the hem are aligned. After sewing, overlock the seams to ensure the sturdiness and durability of the entire garment.

[0081] Sew the sleeve vents: If it is a shirt with sleeve vents, fold the sleeve vent strip over and iron it flat. Then, sandwich the sleeve in the middle and sew along the edge to form a visible seam. Finally, seal the sleeve vent opening with a triangle and press the visible seam to ensure the vent's sturdiness and appearance.

[0082] S3: Wash, dry, iron, and shape to obtain a billiards shirt.

[0083] Prepare ironing equipment such as an iron and ironing board, and adjust the ironing temperature according to the characteristics of the shirt fabric. Then iron each part in turn: start with the collar, turn the collar inside out, and iron back and forth along the shape of the collar to make it crisp and flat. Then iron the cuffs, hem, front, and back in turn. During the ironing process, turn the shirt over frequently to ensure that each part is thoroughly ironed, while avoiding wrinkles or yellowing. After ironing, let the shirt cool and set. Unfold the ironed shirt and check its overall appearance for wrinkles, stains, loose threads, etc. Check if the size of the shirt meets the design requirements and if the proportions of each part are harmonious, such as whether the collar is the right size, the sleeves are the right length, and the overall shirt is symmetrical, ensuring that the shirt's appearance meets quality standards. Check the seams on the garment to see if they are straight and strong, if the stitch spacing is even, and if there are any skipped or broken stitches. Also check the sewing process of each part, such as whether the collar is flat and not curled up, whether the sleeves are neatly attached and can move freely, whether the pockets are secure and straight, and whether the buttons and buttonholes are aligned and can be used properly.

[0084] Check the size: Use measuring tools such as a soft ruler or straight ruler to strictly measure each part of the shirt, including the collar, chest, sleeve length, and garment length, to ensure that the size deviation is within the allowable range. Generally, the allowable deviation for the collar is ±0.5 cm, the allowable deviation for the chest is ±1 cm, and the allowable deviation for the sleeve length and garment length is about ±1.5 cm. If the size deviation is too large, it will affect the comfort and appearance of the shirt.
