Description

Title of the invention: Seamless knitted polo-type garment technical field

[0001] This patent application relates to the technical field of clothing manufacturing, in particular polo shirt-type clothing. Previous art

[0002] Several techniques and processes for manufacturing clothing, including polo shirts, are known in the prior art.

[0003] Traditional polo shirts, for example, are generally made by sewing together different parts of the garment, which involves separate side seams and finishes for the collar, lower body and lower sleeves.

[0004] The major disadvantage of these seams is that they can cause discomfort for the wearer and reduce the durability of the garment.

[0005] In addition, traditional polo shirts often have button-down collars, which increases manufacturing costs and involves additional processes.

[0006] These conventional methods of manufacturing polo shirts can therefore present disadvantages in terms of comfort, aesthetics and production efficiency.

[0007] It is also known from the prior art of seamless knitting techniques, known by the English expression "seamless", but mainly used for sports or lingerie products. Description of the invention

[0008] One of the aims of the invention is to overcome the disadvantages of the prior art, by proposing a polo-type garment whose comfort, aesthetics and production efficiency of this type of garment are improved.

[0009] According to the invention, a polo-type garment has been developed comprising a body and sleeves, each knitted seamlessly, meaning that these elements are knitted in one piece and sewn together, thus eliminating side seams on each element that can cause discomfort for the wearer. The seamless knitting is achieved with a double piqué main knit, which is made of 92% to 96%, preferably 94% polyamide, and 4% to 8%, preferably 6% elastane. This material composition ensures a perfect balance between strength, flexibility, and comfort.

[0010] In single-ply construction, the fabric has a flat and unattractive appearance; in triple-ply construction, this binding causes too many knitting defects (bars, holes, etc.). Furthermore, the fabric is too soft and lacks structure.

[0011] Thus, although progress has been made in the field of clothing and seamless knitting, the patent application aims to introduce a series of specific innovations to create a seamless polo shirt with unique characteristics that distinguish it from traditional polo shirts and previously known seamless knitting techniques.

[0012] Furthermore, tests were carried out by the Applicant: - with a stitched binding using dyed cotton yarn, the result was too dry and cardboard-like to the touch, regardless of the yarn count. The Applicant observed that the seamless circular knitting machine reacts better with synthetic filaments, which are more regular, than with natural fibers which cause defects; - without elastane: the fabric is too soft and takes time to return to its original shape after deformation.

[0013] Preferably, the polyamide used is a polyamide 6 1 / 78 / 68 yarn (number of twisted yarns / yarn size in dtex / number of plies), with half in an S twist and half in a Z twist, which ensures a balanced knit and optimal quality. Without twist, the garment has a twisted appearance. According to other examples, the yarn size can vary between 70 and 85 and the number of plies can vary between 62 and 74.

[0014] Elastane, for its part, is preferably a bare yarn with a count between 20 and 24 dtex, preferably 22 dtex, which offers the necessary elasticity to the garment without compromising its resistance.

[0015] The Applicant attempted to integrate a text or logo in Jacquard binding directly onto the double quilting, but this did not allow for a clear reading of the text, with an unaesthetic appearance due to the presence of white inserts (colour of the quilting) in the black writing (colour of the text).

[0016] According to the invention, the polo-type garment includes a jersey band integrated at the chest and extending around the body. This band allows for the incorporation of legible and high-quality text or logos using Jacquard knitting directly onto the garment during the knitting process. This personalization adds a distinctive and aesthetic feature to the garment, but above all, it eliminates the need for additional manufacturing steps and materials (for example, embroidery or heat transfer).

[0017] In order not to impair the aesthetics of the polo shirt and to avoid the presence of unsightly gathers at the change of weave, the band mesh is preferably slightly less tight than the body mesh, with a difference of between 25% and 35%, and for example about 30%.

[0018] Another notable feature is the garment's collar. Unlike traditional polo shirts, which have a buttoned collar, the polo shirt of the invention preferably has a V-neck without buttons or buttonholes. This buttonless V-neck is formed separately, during a manufacturing step, adding a less conventional and sportier style touch to the garment.

[0019] This type of collar simplifies the manufacturing process and reduces costs.

[0020] Preferably, hems at the bottom of the body and sleeve hems are directly integrated into the knit during the knitting process, with a double piqué binding, preferably held in place by a covered yarn with an elastane core and a polyamide cover with a count between 65 and 70 dtex, for example 67 dtex. This integration eliminates the need to acquire additional ribbing supplies and simplifies manufacturing.

[0021] To ensure the V-neck holds its shape, a fusible interfacing strip is preferably inserted between two layers of piqué fabric at the neckline. This interfacing strip keeps the collar in shape, thus improving the appearance of the garment.

[0022] In summary, the polo-type garment of the invention is distinguished by its seamless knit, its optimal material composition, its V-neck without buttons, its integration of text in Jacquard knit made possible by the insertion of a jersey band, and its finishes integrated into the knit. These combined features offer a comfortable, aesthetically pleasing, customizable (in the sense of adaptable to each brand), and economical garment.

[0023] The manufacturing process for the polo-type garment begins by knitting the body on one hand and the sleeves on the other on a seamless circular knitting machine, and then sewing them together to form the polo shirt. The main knit is made in double piqué, with the material composition described above.

[0024] During the knitting of the polo shirt body, a jersey band is integrated at the chest and runs around the body, allowing for the incorporation of Jacquard-knit text directly onto the garment. This band is preferably knitted slightly less tightly than the rest of the body to avoid puckering at the join points.

[0025] The hems of the bottom of the body and the bottom of the sleeves are also directly integrated into the knitting during the knitting process.

[0026] After knitting, a post-forming process is applied to fix the knit and the dimensions of the polo shirt. The post-forming parameters, such as temperature, pressure and time, as well as the size of the plate used, are carefully controlled to ensure that the garment retains its shape.

[0027] The process also includes a manufacturing step consisting of forming a V-neck without a button, without a button or buttonhole.

[0028] Finally, to maintain the straight shape of the V-neck, a strip of fusible interfacing is inserted between two layers of piqué at the neckline.

[0029] This innovative manufacturing process makes it possible to create a seamless knitted polo-type garment with distinctive technical and aesthetic characteristics, thus offering superior comfort, a unique style, and increased production efficiency. Brief description of the drawings

[0034] With reference to figures 1 to 4, at least one example of an embodiment of a polo-type garment (1) according to the principles of the invention is described.

[0035] The polo-type garment (1) comprises a body (2) and sleeves (3) knitted separately without seams and sewn together to form the polo shirt (1). The polo shirt (1) is manufactured using an optimal material composition. The main knit is double-knitted (4), which gives it good drape, excellent durability, and an aesthetically desirable thick textured appearance. The composition of this main knit is specifically chosen to combine the advantages of polyamide and elastane.

[0036] Polyamide makes up approximately 94% of the composition and is selected with a half S and half Z twist to ensure balanced knitting and eliminate twisting problems. The choice of polyamide 6 1 / 78 / 68 yarn ensures regularity of the knitting and thus best prevents the appearance of defects at this stage.

[0037] Elastane represents approximately 6% of the composition in the form of bare yarn with a thread count of approximately 22 dtex. This quantity of elastane gives the garment the necessary elasticity for a comfortable fit and great freedom of movement.

[0038] With reference to the illustrated embodiment, a jersey band (5) is directly integrated during knitting at the chest of the body (2) of the polo shirt (1). Since the knitting is carried out on a circular knitting machine, this band (5) goes all the way around the body (2) and also passes over the back. This band (5) is knitted at the same time as the rest of the garment, but its stitch is slightly less tight than that of the main body (2), with a difference of approximately 30% to avoid unsightly puckering at the joining point. The band (5) allows for the incorporation of text (6) using Jacquard knitting directly onto the garment.

[0039] The Jacquard-knitted text (6) can be customized according to the wearer's preferences or the manufacturer's requirements. This feature offers a unique opportunity to add garment-specific patterns, logos, or inscriptions without additional supplies or operations.

[0040] The collar (7) of this polo shirt (1) is preferably formed without buttons or buttonholes, creating a distinctive and modern V-neck style. The V-neck collar (7) is formed from tabs (7a) cut from a knitted tube in the same manner as the main fabric, and a special fusible knit strip is inserted between two layers of piqué. The bottom of the collar (7) is secured with a simple, invisible topstitching along the seam. An inner bias binding for the collar (7), matching the color of the text (6) on the front of the polo shirt (1), is used for aesthetic reasons.

[0041] The V-neck collar (7) offers an aesthetic alternative to the traditional collar while maintaining a comfortable fit. It adds a sporty and casual touch to the garment, distinguishing it from classic polo shirts.

[0042] Hems (8) of the body bottom (2) and sleeve bottoms (3) are integrated directly into the knit during the manufacturing process. This feature eliminates the need to acquire additional ribbing supplies and simplifies production.

[0043] The integrated hems (8) are held together by a braided thread with an elastane core and a polyamide cover, with a thread count of approximately 67 dtex, ensuring their strength and durability. This approach not only offers economic advantages but also improves the garment's resistance to tearing and abrasion.

[0044] The knitting of the body (2) is carried out on a circular seamless knitting machine gauge 28, located in an enclosure at a temperature of 25°C and humidity of 65%, thus guaranteeing the stability of the dimensions of the polo shirt (1).

[0045] This embodiment encapsulates the key principles of the invention, offering a polo-type garment that is comfortable, attractive, and economical. The specific characteristics of the material composition, the jersey band (5), the V-neck collar (7) without buttons, and the finishes integrated into the knit contribute to making this garment an innovative and distinctive product on the fashion market.
