[0004] This application provides a method for producing a 360° all-around sports T-shirt and a T-shirt that significantly improves comfort, freedom of movement, and durability during exercise.

[0005] The embodiments of this application adopt the following technical solutions:

[0006] In a first aspect, embodiments of this application provide a method for producing a 360° all-around sports T-shirt. The method includes: achieving the adaptability of the T-shirt to 360° composite sports by adopting a combination of shoulder and sleeve structure optimization, integrated design of the underarm area, seamless placket sealing treatment, three-dimensional pattern adaptation, and seamless weaving in stress concentration areas.

[0007] The shoulder and sleeve structure is optimized to adopt a small-angle bridging sleeve design.

[0008] The integrated design of the underarm area is to cut the sleeve bottom piece and the front and back side pieces into one piece;

[0009] The seamless bonding treatment of the placket is achieved by using an ultrasonic seamless bonding process on the placket.

[0010] The three-dimensional pattern is adapted by adding abdominal allowance to the front piece and forming an invisible waist-cinching structure by using side seam darts to narrow the waist on the back piece.

[0011] The seamless knitting in the stress concentration area refers to the use of seamless knitting technology in the shoulder transition area and the underarm stress concentration area.

[0012] In some embodiments, the shoulder and sleeve structure is optimized by using a small-angle raglan sleeve, which increases the angle between the sleeve and the shoulder line by 20° to 30° compared to the standard sports T-shirt pattern, allowing for unobstructed 360° arm raising movements.

[0013] In some embodiments, the integrated design of the underarm area further includes: integrating the sleeve bottom piece with the front and back side pieces during the cutting stage, reserving an overlap of 25mm to 35mm, and forming a controllable pleated area under the arm after sewing.

[0014] In some embodiments, the seamless bonding treatment of the placket further includes: using an ultrasonic seamless bonding process to replace the traditional sewing process to treat the placket, so that there are no visible stitches at the joint of the placket, and the total thickness of the placket is ≤1.5mm.

[0015] In some embodiments, the three-dimensional pattern adaptation further includes: the front piece having an additional 20mm-35mm of abdominal allowance and adopting an inclusive structure; the back piece having darts at the side seams, which reduce the waist by 10mm-20mm to form an invisible waist-cinching structure.

[0016] In some embodiments, the seamless knitting of the stress concentration area further includes: employing seamless knitting technology in the shoulder transition area and the underarm stress concentration area to reduce the number of seams in the area.

[0017] In some embodiments, the controllable folds under the armpit naturally release fabric stress during human movement, reducing frictional resistance in the armpit area.

[0018] In some embodiments, the placket treated by the ultrasonic seamless bonding process has a thickness that is reduced by about 40% compared to the placket structure of the traditional sewing process, and there is no curling or lifting after multiple washes.

[0019] In some embodiments, the inclusive structure of the front piece adapts to the protruding features of the lower abdomen and squatting movements, and the invisible waist-cinching structure of the back piece makes the back piece conform to the curve of the lower back, improving support during exercise; the seamless knitting technology eliminates friction points in the shoulder transition area and the stress concentration area under the armpit, improving wearing comfort.

[0020] Secondly, this application also provides a 360° all-around sports T-shirt, which is manufactured using the production method described in the first aspect. The T-shirt is suitable for 360° composite sports scenarios such as fitness, yoga, rock climbing and daily high-intensity activities. When the human body wears the T-shirt to perform arm raising, squatting and circling movements, there is no feeling of restraint due to fabric pulling or body pressure.

[0021] The above-mentioned technical solutions adopted in the embodiments of this application can achieve the following beneficial effects: The method includes: by adopting a combination of shoulder and sleeve structure optimization, integrated design of the underarm area, seamless placket sealing treatment, three-dimensional pattern adaptation, and seamless weaving in stress concentration areas, the T-shirt achieves adaptability to 360° compound movement; the shoulder and sleeve structure optimization adopts a small-angle detachable sleeve design; the integrated design of the underarm area integrates the sleeve bottom piece with the front and back side pieces; the seamless placket sealing treatment adopts an ultrasonic seamless sealing process on the placket; the three-dimensional pattern adaptation increases abdominal allowance on the front piece and forms an invisible waist-cinching structure on the back piece through side seam darts; the seamless weaving in stress concentration areas adopts seamless weaving technology in the shoulder transition area and the underarm stress concentration area. The method of this application significantly improves the comfort and freedom of movement of the T-shirt in 360° all-round movement by increasing the arm raising angle, the underarm dynamic allowance, reducing the placket thickness by applying ultrasonic seamless sealing technology, and adopting a front-panel inclusive design and a back-panel invisible waist-cinching design.

[0031] To make the objectives, technical solutions, and advantages of this application clearer, the technical solutions of this application will be clearly and completely described below in conjunction with specific embodiments and corresponding drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0032] The technical solutions provided by the various embodiments of this application are described in detail below with reference to the accompanying drawings.

[0033] This application provides a method for producing a 360° all-around sports T-shirt, such as... Figure 8 As shown, the method includes: Step S101, achieving T-shirt adaptability for 360° compound movement by adopting a combination of shoulder and sleeve structure optimization, integrated design of the underarm area, seamless placket sealing treatment, three-dimensional pattern adaptation, and seamless weaving in stress concentration areas; the shoulder and sleeve structure optimization adopts a small-angle detachable sleeve design; the integrated design of the underarm area integrates the sleeve bottom piece with the front and back side pieces; the seamless placket sealing treatment uses ultrasonic seamless sealing technology on the placket; the three-dimensional pattern adaptation increases abdominal allowance on the front piece and forms an invisible waist-cinching structure on the back piece through side seam darts; the seamless weaving in stress concentration areas uses seamless weaving technology in the shoulder transition area and the underarm stress concentration area.

[0034] The 360° all-around sports T-shirt production method in this application specifically includes (1) the shoulder sleeve adopts a small-angle detachable sleeve design, and the angle between the sleeve and the shoulder line is increased by 20° to 30° compared with the standard sports T-shirt. The arm lifting angle is increased; (2) the sleeve bottom piece is cut in one piece with the front and back side pieces, and 25mm to 35mm of overlap is reserved to form a controllable pleated area under the armpit; (3) the placket adopts ultrasonic seamless pressing process, and there are no visible stitches at the joint and the total thickness is ≤1.5mm; (4) the front piece is increased by 20mm-35mm of abdominal allowance, and the back piece is 10mm-20mm of waist reduction through side seam darts to form an invisible waist reduction structure; (5) the shoulder transition area and the underarm stress concentration area adopt seamless knitting technology to reduce seams, and the underarm and shoulder areas adopt seamless knitting process to reduce the number of seams.

[0035] Unlike other technologies, sports T-shirts typically use traditional raglan or shoulder sleeve designs, whose armhole curves have a low degree of matching with the human shoulder joint's movement trajectory. This means the T-shirt lacks sufficient freedom of movement in the shoulder area, and the fabric is prone to stretching when the user performs 360° arm-raising movements such as raising, swinging, or circling, leading to restricted movement. A 360° all-around sports T-shirt production method incorporates a 20°-30° arm-raising angle design in the arm area to support unrestricted 360° arm-raising movements.

[0036] Unlike other technologies, the underarm area is a key stress concentration zone for upper limb movement. Existing technologies often use a fixed-stitched sleeve bottom and side panel splicing structure, lacking dynamic allowance. This area is prone to pressure and friction discomfort during large-amplitude movements. A 360° all-around sports T-shirt production method employs an underarm overlapping cutting process with the sleeve bottom and side panel, increasing the dynamic allowance by 25-35mm.

[0037] Unlike other technologies, traditional sewing techniques for the placket area often result in raised stitches and increased thickness, leading to curling and sag after repeated washing, thus affecting the wearing experience. Our 360° all-around sports T-shirt production method utilizes ultrasonic seamless bonding technology at the placket area, reducing placket thickness by 40%.

[0038] Unlike other technologies, existing T-shirt designs often use symmetrical straight silhouettes, neglecting the physiological characteristics of men's bodies, such as a slightly protruding abdomen and a tucked-in waist. Real-world testing shows that for wearers with an abdominal circumference increase of more than 3 cm, the front fabric around the abdomen feels tight when standing or squatting, while the back fabric around the waist feels loose and doesn't fit well, reducing support and aesthetics during exercise. Our 360° all-around sports T-shirt production method features a more inclusive design in the front, adding 20mm-35mm of abdominal allowance, and an invisible waist-cinching design at the side seams of the back.

[0039] In one embodiment of this application, the shoulder sleeve structure is optimized as follows: a small-angle detachable sleeve is adopted, so that the angle between the sleeve and the shoulder line is increased by 20° to 30° compared with the standard sports T-shirt pattern, which can accommodate 360° unobstructed arm raising movements.

[0040] like Figure 1 , Figure 2 as well as Figure 3 As shown, the zero-restraint shoulder sleeve: the small-angle raglan sleeve design increases the arm lifting angle by 20° to 30° compared to the standard sports T-shirt pattern, so as to support 360° unobstructed arm raising movements.

[0041] In one embodiment of this application, the integrated design of the underarm area further includes: integrating the sleeve bottom piece with the front and back side pieces during the cutting stage, reserving an overlap of 25mm to 35mm, and forming a controllable pleated area under the arm after sewing.

[0042] like Figure 1 , Figure 2 as well as Figure 3 As shown, the innovative structure of the underarm area is as follows: the sleeve bottom piece and the front and back side pieces are designed as a single unit during the cutting stage, with a 25 mm to 35 mm overlap allowance. After sewing, a controllable pleated area is formed under the armpit, which can naturally release stress and reduce friction during movement.

[0043] In one embodiment of this application, the seamless bonding treatment of the placket further includes: using an ultrasonic seamless bonding process to replace the traditional sewing process to treat the placket, so that there are no visible stitches at the joint of the placket, and the total thickness of the placket is ≤1.5mm.

[0044] like Figure 1 , Figure 2 as well as Figure 3 As shown, the placket treatment process uses ultrasonic seamless bonding technology instead of traditional sewing, resulting in no visible stitches at the placket joint. The total thickness is ≤1.5 mm, approximately 40% less than the traditional structure (2.5 mm). Figure 4 The image shown is a schematic diagram of the placket appearance of a 360° all-around sports T-shirt produced using an ultrasonic seamless bonding process. Figure 5 The image shown illustrates the open state of the placket in a 360° omnidirectional sports T-shirt production method using ultrasonic seamless bonding technology. Figure 6 The image shown is a schematic diagram of the reverse side of the heat-sealed placket in a 360° all-around sports T-shirt production method using ultrasonic seamless heat-sealing technology.

[0045] In one embodiment of this application, the three-dimensional pattern adaptation further includes: the front piece having an abdominal allowance of 20mm-35mm and adopting an inclusive structure; the back piece having darts at the side seams, which reduce the waist by 10mm-20mm to form an invisible waist-slimming structure.

[0046] like Figure 1 , Figure 2 as well as Figure 3 As shown, the three-dimensional design features: the front panel adopts an inclusive design, adding 20-35mm of abdominal allowance to accommodate a protruding lower abdomen and squatting movements; the back panel adopts an invisible waist-cinching design, using darts at the back seams to reduce waist size by 10mm-20mm, making the back panel conform to the body's curves and improving support during exercise.

[0047] In one embodiment of this application, the seamless weaving of the stress concentration area further includes: using seamless weaving technology in the shoulder transition area and the underarm stress concentration area to reduce the number of seams in the area.

[0048] like Figure 1 , Figure 2 as well as Figure 3 As shown, seamless construction is applied: seamless knitting technology is used in the shoulder transition area and the stress concentration area under the armpit to reduce the number of seams, eliminate friction points, and improve wearing comfort.

[0049] In one embodiment of this application, the controllable fold area under the armpit naturally releases fabric stress during human movement, reducing frictional resistance in the armpit area.

[0050] like Figure 1 , Figure 2 as well as Figure 3 As shown, the stress release and friction reduction implementation of the controllable pleat area under the armpit is based on the aforementioned integrated design of the armpit area. Specifically, the sleeve bottom piece and the front and back side pieces are cut as a single unit with a 25mm-35mm overlap. Then, a flat seam is used to fix the pleat along the edge of the armpit overlap, with a stitch length controlled at 12-14 stitches / 3cm. High-elastic nylon thread is used to match the fabric's tensile properties. After sewing, a uniform and controllable accordion-style pleat area naturally forms under the armpit, with a pleat height of 10-1mm. The fabric is 5mm wide, designed to fit the active area of ​​the armpit. When the body performs 360° compound movements such as raising, circling, and squatting, the skin under the armpit stretches the fabric. This controllable pleated area naturally expands with the range of motion, gradually releasing the tensile stress of the fabric and avoiding direct pulling and pressure on the armpit area. At the same time, the fabric in the pleated area has surface contact friction with the human skin, which effectively reduces the frictional resistance in the armpit area compared to the line contact friction of traditional spliced ​​structures, eliminating the discomfort of chafing and pressure under the armpit during exercise.

[0051] In one embodiment of this application, the placket treated by the ultrasonic seamless bonding process has a thickness that is reduced by about 40% compared to the placket structure of the traditional sewing process, and there is no curling or lifting after multiple washes.

[0052] like Figure 1 , Figure 2 as well as Figure 3As shown, based on the above-mentioned seamless placket bonding process, the specific operating steps and technical parameters are as follows: Select a TPU hot melt adhesive film (0.08-0.1mm thick) of the same material and color as the main fabric of the T-shirt as the bonding medium for placket bonding; smooth the edges of the two placket pieces, remove any rough edges, and then sandwich the TPU hot melt adhesive film at the joint of the two pieces; use an ultrasonic seamless bonding machine for bonding, setting the ultrasonic frequency to 20-25kHz and the bonding temperature to 120-140℃. The speed is 3-5m / min, and the pressing pressure is 0.3-0.5MPa. After the glue is applied, the edges of the placket are trimmed to ensure that there are no visible stitches at the joint of the placket and the overall thickness is ≤1.5mm. Compared with the placket structure of traditional sewing process (thickness of about 2.5mm), the thickness is reduced by about 40%. After multiple water washes (more than 50 standard water washes at a water temperature of 30-40℃, conventional washing mode), there is no glue separation, curling, or lifting at the glued joint, and the flatness and fit of the placket are maintained well.

[0053] In one embodiment of this application, the inclusive structure of the front piece adapts to the protruding features of the human lower abdomen and squatting movements, and the invisible waist-cinching structure of the back piece makes the back piece fit the curve of the human lower back, improving the support during exercise; the seamless knitting technology eliminates friction points in the shoulder transition area and the stress concentration area under the armpit, improving wearing comfort.

[0054] like Figure 1 , Figure 2 as well as Figure 3 As shown, the implementation of the three-dimensional pattern adaptation for inclusiveness and fit, and the implementation of friction point elimination through seamless weaving, are carried out in two parts, both based on the aforementioned three-dimensional pattern design and the aforementioned seamless weaving process:

[0055] The front panel features a cladding structure, while the back panel features an invisible waist-cinching structure. During the front panel cutting, a 20mm-35mm allowance is added horizontally in the area corresponding to the abdomen (10-15cm above the waistline). This allowance is evenly distributed on both sides of the front panel, resulting in a slightly curved, cladding silhouette that accommodates the slightly protruding abdomen. The fabric feels comfortable when standing, and naturally stretches with the body during squatting without any pulling force. During the back panel cutting, triangular darts are created at the side seams. The upper apex of the dart is located 8cm above the back waistline, and the lower apex is located in the lower middle part of the side seam. The waist-cinching amount of the darts is 10mm-20mm. The darts are secured using a blind stitch technique, and the seam allowance is ironed to the inside of the side panel after sewing, forming an invisible waist-cinching structure. This ensures the back panel closely conforms to the curve of the lower back, preventing the fabric from sagging or shifting during movement and improving support for the waist.

[0056] Seamless knitting eliminates friction points: After the seamless knitting process is completed, there are no seams in the shoulder transition area and the stress concentration area under the armpit, eliminating friction points such as raised stitches and fabric delamination at the seams in traditional knitting processes. At the same time, the surface of the fabric in the seamless knitting area that comes into contact with human skin is a smooth knitted surface without hard stitches or splicing edges. When the human body moves, there is a smooth relative movement between the fabric and the skin in this area, completely eliminating the discomfort caused by seam friction and significantly improving the overall wearing comfort.

[0057] This application embodiment also provides a 360° all-around sports T-shirt, which is manufactured using the aforementioned production method. The T-shirt is suitable for 360° composite sports scenarios such as fitness, yoga, rock climbing, and daily high-intensity activities. When the human body wears the T-shirt to perform arm raising, squatting, and circling movements, there is no feeling of restraint due to fabric pulling or body pressure.

[0058] The 360° all-around sports T-shirt produced using the above-mentioned manufacturing method is a highly elastic and quick-drying functional sportswear, suitable for 360° composite sports scenarios such as fitness, yoga, rock climbing, and daily high-intensity activities. When the wearer performs movements such as arm raises (0-360° full angle), squats (90-180°), and limb rotations, there is no pulling or restriction in the shoulder and sleeve areas, no pressure or chafing sensation under the armpits, and no irritation at the placket. The front abdomen and back waist both conform to the curves of the human body, with no overall feeling of fabric pulling or body pressure. Furthermore, after repeated wear and washing, the technical characteristics of each structural part of the T-shirt remain stable, with no deformation, glue separation, or curling, meeting the durability requirements for high-intensity sports. Figure 7 The image shown is a front view of a 360° all-around sports T-shirt.
