Detailed Description of Some Demonstrative Embodiments

[0014] Some embodiments provide underwear and undergarments, particularly for a female wearer; as well as methods and systems for producing such underwear and undergarments.

[0015] For example, the gusset region or a groin-covering / crotch-covering region of the underwear, at its inwardly-facing side (e.g., the fabric side that is facing the human body and that is intended to directly touch the body) has fabric-formed protrusions or fabric-formed capsules / cups / caps / closed caps / open caps / open cups / closed capsules / semi-open capsules / semi-open caps / semi-open cups / dome-shaped caps or protrusions / half-sphere shaped caps or protrusions or inwardly-facing elevated loops or knitted-fabric elements or protrusions, that are facing inwardly towards the body; and they may collect / absorb / store bodily fluids (e.g., sweat, blood, urine, vaginal secretion).

[0016] The underwear of some embodiments can be used as a daily underwear or as an “anytime” underwear or “all days” underwear (e.g., and not only / not necessarily as underwear for female period / menstruation time, or as opposed to “period panty” underwear); and/or may obviate the need to utilize a protection pad or a fluid-capturing pad, thus saving money to the human wearer, avoiding a feeling of inconvenience that some wearers may have when using a protective pad between the underwear and the body, and providing an environmentally-friendly or “green” solution by reducing trash (e.g., used one-time protective pads that are thrown away as garbage).

[0017] The Applicant has realized that some women and teenage females, who use onetime / disposable protective pads for daily protection against vaginal / groin / crutch secretions, do not feel comfortable or convenient due to the protective pad that touches their body, and may prefer to get rid of the need to utilize such protective pad because of the feeling of discomfort or inconvenience, health reasons, allergy or sensitivity to chemicals or synthetic materials from which the protective pad is made, the financial costs, and/or their negative impact on the environment when they arrive at garbage sites. Some embodiments of the present invention may address, reduce or resolve these problems, by providing a functional, comfortable underwear for women which can still capture fluids and vaginal secretion, yet without harming the environment, and without burdening the wearer to insert and keep an additional object (protective pad) between her body and her underwear, and while improving the health and/or hygiene and/or convenience of the wearer.

[0018] The underwear of some embodiments may be Seamless or seam-free, or may be cut-and-sew (C&S) type, or a hybrid underwear that incorporates both types. The main regions and/or the entirety of the underwear may be knitted with any suitable type of knitting, for example, plain, or pique, or rib, or mesh, or other knitting technique, or blends or combinations of two or more knitting techniques (e.g., plain knitting with mesh and/or rib).

[0019] The main regions and/or the entirety of the underwear may be knitted with any suitable type of material(s); for example, Nylon, Polyester, Cotton, Modal yarn or Modal material made from beechwood tree cellulose or beechwood molecules or beechwood cellulose or beechwood fiber, Tencel yarn or Tencel material made from eucalyptus tree or eucalyptus fiber or eucalyptus plants or eucalyptus cellulose or eucalyptus molecules, a polyether-polyurea copolymer yarn or fiber (e.g., Lycra, Spandex, Elastane), natural fiber or yarn, synthetic fiber or yarn, semi-synthetic fiber or yarn (e.g., Rayon, Viscose, , yarn or fiber made from wood pulp or cellulose, yarn or fiber made from bamboo pulp or cellulose, silk, yarn or fiber made from elastomeric monofilament, yarn or fiber made from thermoplastic polyurethane (TPU), or a combination or blend of two or more materials (e.g., 50% cotton and 50% polyester; or 50% cotton and 50% Modal or polyether-polyurea copolymer yarn.

[0020] In some embodiments, the entirety of the underwear, or at least the gusset or crotchcovering or vagina-covering or groin-covering region thereof, is formed of hydrophilic yarn and/or hydrophilic fiber, to attract / capture / absorb fluids or vaginal secretion. In some embodiments, the entirety of the underwear, or at least the gusset or crotch-covering or vaginacovering region thereof, is coated at its body-facing side with a hydrophilic agent or material or coating, to attract / capture / absorb fluids or vaginal secretion. In some embodiments, such coating or agent is only on the body-facing side or inner-side of the gusset region; in other embodiments, such coating or agent is only on the external-side or the outer-side of the gusset region (e.g., facing outwardly, away from the body); in other embodiments, such coating or agent is applied to both sides of the gusset region, or is injected into the gusset’s fabric, or is applied by soaking the entire gusset region (or only one side thereof) in such agent.

[0021] In some embodiments, at least one region of the underwear may be formed of hydrophobic yarn and/or hydrophobic fiber or water-repelling yarn or fiber, to repel bodily fluids, and/or to route or to direct such bodily fluids towards another fabric-region of the underwear that is formed of non-hydrophobic yarn or that is formed of hydrophilic yarn. For example, in some embodiments the gusset or crotch-covering or vagina-covering fabric -region of the underwear may be formed of hydrophilic yarn or fiber, whereas other / neighboring fabric-regions of the underwear may be formed of hydrophobic yarn or fiber or from non- hydrophilic yarn or fiber; to direct or route bodily fluids towards the hydrophilic fabric -region of the underwear. Other suitable combinations or arrangements of hydrophilic yarn and hydrophobic yarn may be used; or similarly, hydrophilic agent / material / coating / finishing / treatment and/or hydrophobic agent / material / coating / finishing / treatment. In some embodiments, such treatment(s) are applied only to or at or on the body-facing side or inner- side of the gusset region; in other embodiments, such treatment(s) are applied only to or at or on the external-side or the outer-side of the gusset region (e.g., facing outwardly, away from the body); in other embodiments, such treatment(s) are applied to both sides of the gusset region, or are performed towards the entire gusset’s fabric, or are applied by soaking or brushing or coating or other technique(s) or by a combination of such two or more techniques. [0022] In accordance with some embodiments, most of the body-covering portions of the underwear may be knitted together with bare Spandex / Lycra, or with Spandex, or with Lycra, optionally covered with Nylon or Polyester or other suitable material. For example, most or all of the underwear may be knitted as a seamless undergarment with Texturized Nylon 6 (or Nylon 6.6) at 78/68/1 Dtex and Bare Spandex at 22 Dtex.

[0023] Some embodiments may provide an underwear having an innovative gusset region or crotch-covering region or vagina-covering region or groin-covering region or genitals- covering region.

[0024] For example, in a Seamless knitting process, the main regions of the underwear may be knitted with conventional wicking property yarns, but when arriving the gusset (or crotchcovering or vagina-covering) region or zone, the knitting machine switches seamlessly to a different yarn and/or utilizes a different knitting structure; for example, switching from the main external fabric yarn, to a Durable Water Repellent yarn (DWR yarn). For example, switching from the Texturized Nylon 6 at 78/68/1 Dtex, to a DWR Polyester yarn or DWR Nylon yarn, to prevent or repel bodily fluids or vaginal secretions from leaking to the outside of the gusset region (or crotch-covering region, or vagina-covering region).

[0025] Additional or alternatively, at the same time of switching, the knitting machine may add seamlessly one or more extra yarns for knitting at the internal side (the body-facing side, the body-touching side) of the gusset region (or vagina-covering region, or crotch-region). The function of these additional internal-facing yarns is to absorb the body fluids and thus remove them from the body’s intimate organs, and to act as anti-odor / anti-microbial component. The extra internal yarn(s) may be, for example, Nylon with permanent anti-odor / anti-microbial property or coating or treatment, such as Nylon 6.6 incorporated with Zinc or Zinc Ions (e.g., “Acteev” yarn available from Ascend Performance Materials of Houston, Texas, USA; or other anti-microbial / anti-odor yarn), or Cotton yarn covered or treated with or coated by an antimicrobial / anti-odor agent, or with anti-odor / anti-microbial Graphene Nylon yarn or composite yarn or filament, or with Tencel, or with blends or combination of two or more yarns (e.g., a blend of 50% of “Acteev” Nylon at 78/68/1 Dtex and 50% Tencel / Lyocell 60/1 Ne.

[0026] The gusset region (or groin-covering region, or crotch-covering region, or vaginacovering region) may be knitted in plain knitting technique, or rib 1x1, or rib 2x1, or rib 3x1, or pique 1x1, or diagonal 2x2, or pique 3x1, or any other needle “Miss X Clear” distribution knitting pattern; or can be knitted with needle catch (“rushing”) of 2 rows or 3 rows or 4 (or more) rows. The needles catch can be, for example, 1x1 or 2x1 or 2x6 or any other needle distribution / knitting pattern. Alternatively, it may be knitted in mesh technique, such as mesh 1x1, or mesh 2x1, or mesh 3x1, or other needles distributions / knitting pattern. In some embodiments, the gusset region (or crotch-covering region, or vagina-covering region) may be knitted as terry knitted structure, or “real” terry knitted structure (e.g., having raised uncut loops), or “fake” / imitation terry knitted structure. In some embodiments, the gusset region (or crotch-covering region, or vagina-covering region) may be knitted using two or more different knitting techniques at the same gusset.

[0027] The knitting techniques that are used, together with the selected yarns that are knitted, may create a plain-looking / regular-looking gusset, or a rib looking gusset, or pique looking gusset, or may have any suitable graphic design (e.g., a flower graphic design gusset, or diamonds design gusset, or a drop or a rain-drop design or structure).

[0028] In some embodiments, the gusset region (or groin-covering region, or crotchcovering region, or vagina-covering region) may have two or three or multiple different knitting zones or knitted regions; some of them are demonstrated herein. [0029] In a first example, there are three fabric-zones in the gusset fabric -region, and they are denoted Zone A and Zone B and Zone C. For example, Zone A is a flat frame around Zone B, to provide a comfort feeling, and to additional protection against fluid leaks to the sides. Zone B is located between Zone A and Zone C, and can store or absorb secretory fluids at a medium level / medium capacity, and can provide a smooth transition from Zone C towards Zone A Then, Zone C is located at the center of the gusset region; and serves as a container / absorber / collector of the main volume of secretion discharge or bodily fluids. In some embodiments, Zone C is structured and knitted to integrally have body-facing capsules or protrusions or ribs; optionally structured as functional cups or liquid-holders having the capability to contain and trap the wearer’s bodily fluids / secretion fluid. In some embodiments, the fabric-region Zone C is elevated inwardly relative to Zone B and to Zone A; and similarly, Zone B is elevated inwardly relative to Zone A. In some embodiments, Zone C is elevated inwardly relative to Zone B and Zone A, which in turn are at the same elevation level. In some embodiments, optionally, In some embodiments, the fabric -region Zone C is elevated inwardly relative to Zone B and to Zone A; and similarly, Zone B is elevated inwardly relative to Zone A; and similarly, Zone A is elevated relative to other fabric -regions of the underwear (e.g., the front and/or the back fabric-regions of the underwear).

[0030] In accordance with some embodiments, Zone A is a knitted frame of fabric around (surrounding) Zone B, which is a fabric “island” within Zone A; and similarly, Zone B is a knitted frame of fabric around (surrounding) Zone C, which is a fabric “island” within Zone B; such that all the three zones (A and B and C) are at the same plane / the same height level / the same distance from the skin of the human wearer; and the three zones are Not three layers one on top of the other.

[0031] In some embodiments, Zone C may have fabric-made protrusions, such as having a volume of 4 or 6 or 8 or 10 or 12 or 15 cubic millimeters (or 4 to 10, or 4 to 15 cubic millimeters) per protrusion, to protrude inwardly towards the human body, without irritating the body yet having sufficient volume to absorb and store fluids therein. In some embodiments, each protrusion may be a sphere or half-sphere or dome shaped; having a height of 2 or 3 or 4 or 5 millimeters (or a height of 2 to 5 millimeters; or a height of 3 to 5 millimeters), and/or having diameter of 5 to 10 millimeters. The Applicant has realized that integrally incorporating such protrusions, specially and only at the body-facing side of the gusset region, may provide an enhanced functionality of fluids absorption, while at the same time still providing a pleasant and non-irritating feeling to the wearer. In some embodiments, each protrusion may be shaped as a cup or as a hollow cup, or as a hollow cylinder having an opening on one side, in order to receive and trap therein some of the bodily fluids; such that even if some portion of the bodily fluid can still exist some of such “open cups” elements, the plurality of such “open cups” can still trap and hold therein a substantial volume of bodily fluids and may thus provide sufficient utility and advantage to the wearer. The Applicant has realized that even capturing / trapping / absorbing even some of the bodily fluids, and not necessarily all of their volume, can still be advantageous and beneficial to many wearers, and can still provide utility and benefits to many wearers.

[0033] Reference is made to Fig. IB, which is a schematic illustration of another underwear 102, in accordance with some demonstrative embodiments; shown as spread-open in a cut-open view, observing the inner side of the underwear; demonstrating the three zones (A and B and C) of the gusset region (or vagina-covering / crotch-covering / groin-covering region); demonstrating zones having only one-side symmetry (e.g., vertical symmetry as shown, and horizontal non-symmetry as shown) for enhanced convenience and functionality. [0034] Reference is made to Fig. 1C, which is a schematic illustration of another underwear

103, in accordance with some demonstrative embodiments; shown as spread-open in a cutopen view, observing the inner side of the underwear; demonstrating the three zones (A and B and C) of the gusset region (or vagina-covering / crotch-covering / groin-covering region); demonstrating Zone C having double symmetry (e.g., vertical symmetry and also horizontal symmetry) for enhanced convenience and functionality.

[0035] Reference is made to Fig. ID, which is a schematic illustration of another underwear

104, in accordance with some demonstrative embodiments; shown as spread-open in a cutopen view, observing the inner side of the underwear; demonstrating the three zones (A and B and C) of the gusset region (or vagina-covering / crotch-covering / groin-covering region); demonstrating Zone C having double symmetry (e.g., vertical symmetry and also horizontal symmetry) for enhanced convenience and functionality.

[0036] Reference is made to Fig. IE, which is a schematic illustration of another underwear

105, in accordance with some demonstrative embodiments; shown as spread-open in a cutopen view, observing the inner side of the underwear; demonstrating the three zones (A and B and C) of the gusset region (or vagina-covering / crotch-covering / groin-covering region); demonstrating that each of the three zones (A and B and C) has double symmetry (e.g., vertical symmetry and also horizontal symmetry) for enhanced convenience and functionality.

[0037] In some embodiments, the innovative gusset fabric-region performs absorption of bodily liquids, in an efficient and comfortable way, by its division into multiple zones, such as Zone A which surrounds Zone B which surrounds Zone C. For example, the gusset may be knitted on a Seamless knitting machine, 28gg. The external yarn (e.g., facing away from the body, away from the skin, not directly touching the skin) may be: Spandex or Delicate Spandex covered with Nylon or delicate Nylon, to get a comfortable attachment of the fabric to the body. The internal yarn (e.g., directly touching the skin and the intimate organs) may be: Spun Tencel yarn, for soft touch and a high level of liquid absorption. In some embodiments, in a wet processing stage of the fabric, a Hydrophilic softener / coating / material / soaking agent can be added or soaked or brushed or otherwise applied, to enhance the absorption capability of liquids by the gusset. Optionally, to prevent or reduce liquids from leaking out of the crotch / groin region, some embodiments may add a fabric coated with Teflon foil on (or under) the outside / external side of the groin / crotch region of the underwear; and/or, other embodiments may use a knitted durable water-repellent yarn on (or under) the outside / external side of the groin / crotch region of the underwear. In some embodiments, a passivation process or passivation treatment or passivation coating may be applied to Zone C and/or Zone B and/or Zone A, or a passivation film or passivation coating or a protective oxide layer may be added to one of them or to some of them or to all of them; and/or other suitable and functional coating layer(s) may be added or brushed or coated or applied to Zone A and/or Zone B and/or Zone C (e.g., an anti-odor coating layer, an anti-microbial coating layer, or the like), as an integrated layer or as a separate layer.

[0038] Reference is made to Fig. 2, which is a schematic illustration of a knitting pattern 200 or a knitting construction of the gusset fabric -region, in accordance with some demonstrative embodiments. It demonstrates the open stretching pattern knitting commands, of the total seamless underwear, showing also the three knitted, differential, gusset zones (Zone A and Zone B and Zone C).

[0039] Reference is made to Fig. 3A and Fig. 3B and Fig. 3C, which are schematic illustrations of knitting patterns 301 and 302 and 303, respectively, which may correspond respectively to Zone A and Zone B and Zone C of the gusset fabric -region, in accordance with some demonstrative embodiments. [0040] Referring to Zone C, for example, Yellow (lightest color) squares indicate Plain knitting; Red (medium color) squares indicate floating of Tencel / Refibra / Lyocell yarn or fabric at the Even feeds, to create a fabric effect that is similar to Terry or that is “fake Terry” or “imitation Terry” knitting, such as closed raised loops; Black (darkest color) squares indicate knitting with needle catch-and-miss, such as 8 rows and then 4 rows, to create a raised condensed fabric effect.

[0041] Referring to Zone B, for example, the catch-and-miss knitting pattern is reduced to 4 rows + 4 rows, or reduced to 4 needles, to achieve a fabric effect that is still protruding relative to plain knitting but is also less protruding relative to Zone C.

[0042] Referring to Zone A, for example, the catch-and-miss knitting pattern is further reduced or further diluted, or the needle catch occurrences are further diluted, to achieve a fabric effect that is still slightly protruding relative to plain knitting but is also less protruding relative to Zone B.

[0043] Some embodiments thus provide an innovative gradual transition, from the raised and fleshy area of Zone C, then to the less elevated and thickened area of Zone B, and finally to the flat or almost-flat area of Zone A; thus providing a gusset fabric -region that is adapted to the anatomical structure of the female groin area, which on the one hand provides a solution for efficient fluid absorption, and on the other hand provides a pleasant and comfortable feeling while being worn.

[0044] In some embodiments, Zone A of the gusset fabric -region is flush relative to the front-side fabric of the underwear and relative to the back-side fabric of the underwear; such that Zone A as well as the front-side fabric of the underwear and the back-side fabric of the underwear are all at the same level or the same plane, and such that they all have the same thickness or height. In other embodiments, Zone A of the gusset fabric-region is thicker relative to the front-side fabric of the underwear and the back-side fabric of the underwear; for example, Zone A may be 1.25 or 1.5 or 2.0 or 2.5 times thicker, or may be thicker by 1.25 to 2.5 times relative to the thickness of the front-side fabric of the underwear and the back-side fabric of the underwear. In some embodiments, Zone B may be 1.25 or 1.5 or 2.0 or 2.5 times thicker than Zone A, or may be thicker by 1.25 to 2.5 times relative to the thickness of Zone A. In some embodiments, Zone C may be 1.25 or 1.5 or 2.0 or 2.5 or 3.0 times thicker than Zone B, or may be thicker by 1.25 to 3.0 times relative to the thickness of Zone B. These particular ratios and thickness levels, of the “island” of Zone C within the “island” of Zone B which is within Zone A, provides a comfortable transition as well as efficient fluid absorption capability. [0045] In some embodiments, elongated island-shaped fabric -region Zone C of the gusset is characterized by having a first knitting structure; and is surrounded by an elongated frame / oval-shaped fabric -region Zone B of the gusset that is characterized by a having a second, different, knitting structure; which in turn is surrounded by an elongated frame / oval-shaped fabric-region Zone A of the gusset that is characterized by a having a third, different, knitting structure (different from both the knitting structure of Zone B and the knitting structure of Zone C); thereby providing an innovative differential knitting structure across the different zones of the gusset, which in turn - realized the Applicant - provide enhanced liquid absorption and/or accommodation for the body contour and physical structure of the groin area and/or a pleasant feeling to the user via the gradual change of knitting structures towards the zone (Zone C) that directly covers the intimate organs.

For example, an underwear for men may include a gusset fabric-region and/or a pouch fabric-region, or an integrated continuous gusset-and- pouch fabric region, that may include multiple Zones as described above, and/or that may include at least a first zone (such as Zone C) that is surrounded by at least a second zone (such as Zone B or Zone A); and/or may include the above-mentioned fabric-made protrusions or caps or elevated loops that are facing inwardly towards the body of the human wearer to provide improved absorption and/or body clinging characteristics.

[0068] Some embodiments of the present invention may include a clothing article, such as a shirt or blouse or sweatshirt, intended to cover the top-half of the body or the upper-third of the body or the chest, that similarly incorporate the features of the gusset region described above at particular regions that are prone to sweat accumulation or sweat release, such as the fabric-regions that cover the armpits or that are beneath the armpits; to absorb sweat and/or to reduce unpleasant odor. For example, a shirt or sweatshirt may include a fabric -region covering beneath the armpit, that may include multiple Zones as described above, and/or that may include at least a first zone (such as Zone C) that is surrounded by at least a second zone (such as Zone B or Zone A); and/or may include the above-mentioned fabric-made protrusions or caps or elevated loops that are facing inwardly towards the body of the human wearer to provide improved absorption and/or body clinging characteristics beneath the armpits of the human wearer.

[0069] Some embodiments may be implemented by using a machine or an automated or semi-automatic production line, which may comprise, for example: cutting unit, welding unit, bonding unit, ultrasonic operations unit, gluing unit, conveyor belt, robotic arm, control unit, workstation; as well as suitable hardware components and/or software components, for example, processor to execute code, memory unit, storage unit, input unit (keyboard, mouse, touch-screen), output unit (screen, touch-screen), modems, transceivers or transmitters or receivers, wireless and/or wired communication links and/or transceivers or transmitters or receivers, power sources, Operating System (OS) and suitable applications, or the like.

[0070] Some embodiments revolve around the development of innovative underwear and undergarments, specifically designed for female wearers, which address common issues related to comfort, health, cost, and environmental impact. The core of the solution lies in the gusset region, which features fabric-formed protrusions or capsules designed to absorb and store bodily fluids such as sweat, blood, urine, and vaginal secretions. Some embodiments may provide a daily underwear solution that eliminates the need for disposable protective pads, offering an environmentally friendly alternative that is also cost-effective and comfortable.

[0071] Some key features of the underwear include the seamless integration of the gusset region with the rest of the garment, which can be made using various knitting techniques and materials. The underwear can be produced using seamless or cut-and-sew (C&S) methods, or a hybrid of both. The materials used in the production can include a wide range of natural, synthetic, and semi-synthetic fibers such as Nylon, Polyester, Cotton, Modal, Tencel, Spandex, and/or others. The selection of materials ensures that the underwear is both comfortable and functional, with options for hydrophilic and hydrophobic yarns to manage fluid absorption and repulsion effectively.

[0072] The gusset region is particularly innovative, featuring different zones (Zone A, Zone B, and Zone C) with specific knitting structures and material properties to optimize fluid absorption and comfort. Zone C, located at the center, is designed to absorb the main volume of secretions and may include fabric-formed protrusions or cups that help trap and hold fluids. Zone B provides a transition between Zone C and Zone A, absorbing a moderate amount of fluids, while Zone A surrounds the other two zones, offering additional protection and comfort. [0073] The differential knitting structures across the zones are designed to match the anatomical structure of the female groin area, providing efficient fluid absorption and a pleasant wearing experience. For instance, Zone C might use Terry knitting structures to create raised loops that enhance absorption, while Zones A and B use different structures to achieve a comfortable transition and fluid management. The innovative design ensures that the gusset region can handle fluid absorption effectively without adding bulk or discomfort to the wearer. [0074] Additionally, some embodiments include potential treatments and coatings to enhance the functionality of the underwear. Hydrophilic agents or coatings can be applied to the body-facing side of the gusset to increase fluid absorption; and/or, hydrophobic treatments can be used on the external side to prevent leakage. Anti-microbial and anti-odor treatments, such as Zinc ions or Aloe Vera, can be incorporated to improve hygiene and comfort.

[0075] Some embodiments may further use pre-laminated fabrics with materials like Teflon or Poly-tetra-fluoro-ethylene (PTFE) to provide an additional barrier against fluid leakage. These fabrics can be attached to the underwear using various techniques, ensuring that the garment remains functional and comfortable.

[0076] The versatility of some embodiments may go beyond female underwear. The described features can be adapted for use in non-undergarment clothing articles such as pants, leggings, activewear, and even shirts, particularly in regions prone to sweat accumulation like armpits. Furthermore, some embodiments can be modified to create male underwear with similar fluid absorption capabilities, addressing issues like urine drips and sweat.
