Abstract

This invention discloses an antibacterial sweat-absorbing pad for underarms and its preparation method. The underarm pad includes a sweat-absorbing pad body and a waterproof edging fabric. The sweat-absorbing pad body consists of a sweat-absorbing section and a waterproof layer. The sweat-absorbing section comprises a sweat-absorbing surface layer, a sweat-retaining intermediate layer, and a sweat-retaining bottom layer connected sequentially from the inside out. The sweat-absorbing surface layer is in direct contact with the skin under the armpit. The waterproof layer is located on the outer side of the sweat-retaining bottom layer. A waterproof edging fabric is sewn around the outer edges of the sweat-absorbing surface layer, the sweat-retaining intermediate layer, and the sweat-retaining bottom layer to the waterproof layer, thus fixing the sweat-absorbing surface layer, the sweat-retaining intermediate layer, and the sweat-retaining bottom layer together with the waterproof edging fabric.

The three-layer structure of the sweat-absorbing section is formed in one piece on a machine through structural design, exhibiting good extensibility and elasticity, and requiring no bonding between the layers, allowing for breathability and moisture permeability.

Description

Technical Field

[0001] This invention relates to padding or protective layers for specific parts of clothing, specifically an underarm antibacterial and sweat-absorbing pad and its preparation method. Background Technology

[0002] With improved living standards and increased awareness of personal care, people are placing greater emphasis on the comfort and functionality of clothing. The armpits are an area prone to sweating year-round; strenuous exercise, hot weather, and emotional stress can all lead to overactive sweat glands. Furthermore, a damp armpit breeds bacteria, which is detrimental to health. The armpits contain abundant eccrine and apocrine glands; the proteins and fats secreted by apocrine glands can be broken down by Staphylococcus aureus and aerobic Corynebacterium, resulting in volatile body odor. Sweat-soaked and corrosive substances can also affect the appearance of clothing.

[0003] To address this problem, researchers have employed sweat-absorbing, antibacterial, and odor-removing technologies.

[0004] 1. In sweat-wicking technology, research on sweat-wicking surface fabrics and improvement of the fabric's water absorption and wicking performance require the rational use and combination of hydrophilic and hydrophobic fiber raw materials and the design of suitable organizational structures to enhance the fiber's moisture-wicking capacity and diffusion speed, increase the moisture dissipation area, and enable sweat to be quickly conducted from the sweat-wicking surface layer to the sweat-storing layer, keeping the skin-friendly sweat-wicking layer comfortable.

[0005] Currently, common methods for dealing with underarm sweat include using disposable sweat patches, wearing sweat-wicking vests or short-sleeved shirts with sweat-wicking linings, and applying antiperspirants. For example, document application number 201610300980.6 discloses a method for preparing an underarm sweat patch, which has a three-layer structure, including a sweat-absorbing surface layer, a sweat-retaining middle layer, and a waterproof bottom layer. The bottom surface of the sweat patch has an adhesive backing, which is used to bond it to clothing. However, its sweat-absorbing surface layer uses disposable non-woven fabric, resulting in material waste and recycling difficulties; the layers need to be bonded together, and the patch itself has no extensibility or elasticity; the bottom layer is bonded to the clothing with adhesive backing, which is not firmly attached to the fabric, easily deformed or falling off, and the fabric surface is uneven after bonding, affecting the appearance; the adhesive backing can easily cause skin irritation and discomfort.

[0006] 2. Antibacterial technology can be broadly categorized into using natural antibacterial fibers, spinning raw materials with added antibacterial components, and finishing with antibacterial agents. Synthetic fibers containing antibacterial agents, as well as compounds found in natural plants such as mugwort, mint, and licorice, can inhibit the energy supply of bacteria. Natural animal-derived antibacterial components, such as chitosan and chitin, can cause bacterial death through the binding of positive and negative charges. Adding these plant and animal extracts to the spinning solution for blending or composite spinning can yield products with long-lasting antibacterial effects.

[0007] Application No. 202220149141.X discloses a sweat-absorbing pad with antibacterial and deodorizing functions. The pad body is composed of a cotton surface layer, a dust-free paper, a bactericidal layer, and a polyethylene bottom film bonded together, from top to bottom. The bactericidal layer is formed by sprinkling the bactericidal agent Kangfeng AOP-KF solid alkali onto the dust-free paper or by mixing the bactericidal agent and a superabsorbent polymer material and then sprinkling it onto the dust-free paper. The pad body has several water-locking holes embossed on it to fix the bactericidal agent and the absorbent material. The shape of the sweat-absorbing patch is petal-shaped, butterfly-shaped, mushroom-shaped, or oval. Application No. 202020599472.4 discloses an underarm pad, which has a bactericidal part set on the absorbent part of the symmetrical fan-shaped sweat-absorbing patch. The bactericidal part contains silver ion bactericidal particles that can destroy bacterial function.

[0008] 3. Regarding the problem of body odor, researchers have developed corresponding solutions: (1) Use antibacterial yarn or antibacterial finishing to destroy bacterial activity and inhibit bacterial reproduction at the source. (2) Use deodorizing fibers. (3) Use additional fragrance granules or fiber materials with natural fragrance to cover up body odor with the emitted fragrance. Summary of the Invention

[0009] To address the shortcomings of existing technologies, the technical problem this invention aims to solve is to provide an underarm antibacterial sweat-absorbing pad and its preparation method.

[0010] The technical solution of this invention to solve the aforementioned technical problem is to provide an underarm antibacterial sweat-absorbing pad, characterized in that the underarm pad includes a sweat-absorbing pad body and a waterproof edging fabric; the sweat-absorbing pad body is composed of a sweat-absorbing part and a waterproof layer; the sweat-absorbing part is composed of a sweat-absorbing surface layer, a sweat-retaining intermediate layer, and a sweat-retaining bottom layer connected sequentially from the inside to the outside; the sweat-absorbing surface layer is in direct contact with the human underarm skin; the waterproof layer is disposed on the outside of the sweat-retaining bottom layer; a waterproof edging fabric is sewn around the outer edge of the sweat-absorbing surface layer, the sweat-retaining intermediate layer, and the sweat-retaining bottom layer and the waterproof layer, thereby fixing the sweat-absorbing surface layer, the sweat-retaining intermediate layer, and the sweat-retaining bottom layer together with the waterproof edging fabric.

[0011] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0012] (1) This invention utilizes knitting technology to prepare underarm pads, which, compared to disposable nonwoven fabrics, can be reused repeatedly, saving resources. The three-layer structure of the sweat-absorbing part is formed in one piece on the machine through structural design, which has good extensibility and elasticity, and the layers do not need to be bonded together, making it breathable and moisture-wicking.

[0013] (2) The present invention combines the ergonomic design of the pad shape, which is naturally integrated with the human body and clothing when worn; the connection method with clothing is more flexible, and can be connected by sewing or by Velcro, without the need for adhesive backing, avoiding problems such as deformation, misalignment, twisting and slippage, and adhesive residue; it can also be directly sewn onto the outer garment, avoiding the stuffiness and binding feeling caused by an extra layer of fabric, using less fabric and reducing costs.

[0014] (3) The sweat-absorbing surface layer of the present invention adopts a looped mesh structure woven with alternating hydrophilic and hydrophobic yarns with antibacterial and deodorizing functions. It is comfortable and breathable, has good sweat absorption and retention properties, prevents staining of clothing, and does not cause chemical irritation to the skin contact surface, and does not clog sweat glands.

[0015] (4) The loop structure in this invention connects the three layers of the sweat-absorbing part into a whole. The regularly distributed pores facilitate the breathability and water wicking of the fabric. Human underarm sweat is quickly absorbed by the hydrophilic fibers of the sweat-absorbing surface layer and then conducted along the planar direction to other yarns or downwards through the sweat-retaining intermediate layer to the sweat-retaining bottom layer for diffusion. The sweat-retaining intermediate layer has a certain thickness. The parts of the upper and lower layers connected by the loop structure are constrained by the loops and are in a concave state. The remaining parts not connected by the loop structure are in a free and fluffy state, forming the raised parts on the fabric surface. This uneven texture helps to reduce the contact area between the sweat-absorbing pad and the human skin, thereby achieving a breathable and dry effect.

[0016] (5) The sweat-absorbing surface is designed with alternating rows of hydrophilic and hydrophobic yarns, which allows for rapid diffusion and conduction of sweat. Compared to a surface entirely made of hydrophilic yarns, this yarn arrangement makes the underarms drier because hydrophobic fibers have poor water retention and do not retain sweat for long periods. They can transfer moisture quickly through conduction between fibers. At the same time, compared to a surface entirely made of hydrophobic yarns, this yarn arrangement can absorb sweat more quickly because hydrophilic fibers have good moisture absorption. Sweat can be immediately absorbed and moistened by the fibers when it comes into contact with them.

[0017] (6) Combining ergonomics, the shape of the underarm antibacterial sweat pad is designed as a symmetrical wing shape or goldfish shape, which fits naturally with the human body when used, without affecting sweating or appearance. Attached Figure Description

[0035] Specific embodiments of the present invention are given below. These specific embodiments are only used to further illustrate the present invention in detail and do not limit the scope of protection of the claims of the present invention.

[0036] This invention provides an antibacterial sweat-absorbing pad for underarms (hereinafter referred to as underarm pad), characterized in that the underarm pad includes a sweat-absorbing pad body 1 and a waterproof edging fabric 2; the sweat-absorbing pad body 1 is composed of a sweat-absorbing part and a waterproof layer 14; the sweat-absorbing part is composed of a sweat-absorbing surface layer 11, a sweat-retaining intermediate layer 12 and a sweat-retaining bottom layer 13 connected sequentially from the inside to the outside, forming a three-layer integrated sandwich knitted structure; the sweat-absorbing surface layer 11 is in direct contact with the skin under the armpit; the waterproof layer 14 is set on the outside of the sweat-retaining bottom layer 13; a waterproof edging fabric 2 is sewn around the outer edge of the sweat-absorbing surface layer 11, the sweat-retaining intermediate layer 12 and the sweat-retaining bottom layer 13 and the waterproof layer 14, and the sweat-absorbing surface layer 11, the sweat-retaining intermediate layer 12 and the sweat-retaining bottom layer 13 and the waterproof layer 14 are sewn together by the waterproof edging fabric 2, and at the same time protect the yarn in the sweat-retaining intermediate layer 12 from being unraveled due to washing or other external forces.

[0037] Preferably, the sweat-absorbing surface layer 11 is a layer structure in which the ground weave is a plain knit weave, and the yarns are arranged alternately in the weft direction according to the hydrophilic and hydrophobic properties. The weft direction is a spaced-out layer structure with regular distributed loop holes and hydrophilic and hydrophobic areas distributed in the warp direction. The loop holes are water-absorbing and breathable points, and they are short linear, long linear, elliptical, diamond-shaped and continuous hexagonal.

[0038] To avoid continuous loops in the same row or column, and to prevent excessive pressure on the machine from excessive loops within the pattern cycle, all five perforation structures present simple and regular patterns. Short linear perforations have the fewest loops and the fewest connection points between the surface and inner layers among the five structures; extending the loop point lines appropriately yields long linear perforations; inspired by the superior absorbency of honeycomb structures, elliptical and diamond-shaped perforations were designed; continuous hexagonal perforations have the most loops within the cycle and the most connection points between the surface and inner layers.

[0039] Preferably, the sweat-retaining intermediate layer 12 is inserted between the sweat-absorbing surface layer 11 and the sweat-retaining bottom layer 13 by means of weft weaving.

[0040] Preferably, the sweat-storing bottom layer 13 is made of weft-needle fabric.

[0041] Preferably, the waterproof layer 14 is a knitted fabric made of polyester or modal / cotton / spandex that has undergone waterproof treatment and has waterproof and breathable properties.

[0042] Preferably, the waterproof edging fabric 2 is a waterproof-treated modal / cotton / spandex knitted fabric; the waterproof treatment prevents sweat absorbed by the absorbent pad body 1 from seeping into the garment through the edging. The width of the waterproof edging fabric 2 is 0.3–0.6 cm.

[0043] Preferably, the waterproofing finish is achieved by dip-and-roll, spraying or roller coating, followed by baking at 160-170°C for 2 minutes, with the amount of waterproofing agent being 60-100 g / L.

[0044] Preferably, the waterproofing agent in the waterproofing finishing process is formulated from a water-based, fluorine-free polyurethane waterproofing agent and a waterproofing crosslinking agent. The fluorine-free waterproofing agent is a weakly cationic milky white to pale yellow liquid, composed of polyurethane copolymer, tripropylene glycol ether, and water, suitable for materials such as polyester and cotton, and provides an anti-wicking effect. The waterproofing crosslinking agent is a weakly cationic milky white to beige dispersion containing a capped isocyanate polymer, which, when combined with the waterproofing agent, can greatly improve waterproofing and wash resistance. The mass ratio of the waterproofing crosslinking agent to the fluorine-free waterproofing agent is 1 to 2:1, which helps to enhance the waterproofing and wash resistance effect, and the amount of reagent can be adjusted according to cost.

[0045] Preferably, the warp direction of the three layers of fabric in the sweat-absorbing part of the underarm pad is the same as the transverse direction of the underarm pad.

[0046] Preferably, the underarm pad is divided into four regions: a, b, c, and d, by a longitudinal reference line (MN) and a transverse reference line (PQ). Region a corresponds to the underarm position on the front of the chest, region b corresponds to the underarm position on the front of the arm, region c corresponds to the underarm position on the back of the chest, and region d corresponds to the underarm position on the back of the arm. In other words, region ac (i.e., regions a and c) corresponds to the underarm position on the chest, region bd corresponds to the underarm position on the arm, region ab corresponds to the underarm position on the front of the body, and region cd corresponds to the underarm position on the back of the body. The transverse and longitudinal reference lines of the sweat-absorbing pad help determine the seam position.

[0047] Preferably, the planar shape of the underarm pad is symmetrical wing-shaped (e.g., Figure 2 (as shown) and goldfish-shaped (as shown) Figure 3 (as shown);

[0048] Preferably, to make the sweat-absorbing pad fit the clothing and the underarm area of ​​the body better, referring to clothing ergonomics, and based on the shape of the armpit root area and the positions of the front and rear armpit points, the underarm pad is designed as a symmetrical wing-shaped structure. In the symmetrical wing-shaped structure, the longitudinal length and lateral width of area a and area b are equal, and the longitudinal length and lateral width of area c and area d are equal. In this embodiment, the longitudinal length and lateral width of area a and area b are equal, with the longest longitudinal length being 6cm and the widest lateral width being 6cm; the longitudinal length and lateral width of area c and area d are equal, with the longest longitudinal length being 5cm and the widest lateral width being 5.5-6cm; the longitudinal reference line is located at the central axis of the underarm pad, and the lateral reference line divides the underarm pad into upper and lower parts in a 6:5 ratio; the overall maximum lateral width of the underarm pad is 12cm, the maximum longitudinal length is 11cm, and the minimum length of the longitudinal central indentation is 7.5-8cm.

[0049] Preferably, the design incorporates a targeted asymmetrical approach, referencing the sweating areas on the sides of the armpit and the front and back of the armpit. Generally, the area of ​​sweating on the side of the armpit is larger than that on the back, and the front of the armpit is larger than the back. The outer side is then appropriately lengthened based on the range of motion of the arm, resulting in a goldfish-shaped armpit pad. In this goldfish-shaped structure, the lateral width of region ac (side of the body) is greater than that of region bd (side of the arm), the longitudinal length of region ab (front of the body) is greater than that of region cd (back of the body), and the longitudinal length of region bd (side of the arm) is slightly greater than that of region ac (side of the body). In this embodiment, the longest vertical length of region a is 5-5.5cm, and the widest horizontal length is 7.5-8cm; the longest vertical length of region b is 6cm, and the widest horizontal length is 5-5.5cm; the longest vertical length of region c is 4cm, and the widest horizontal length is 7cm; the longest vertical length of region d is 4-4.5cm, and the widest horizontal length is 4.5cm; the vertical reference line is located at the vertical recess of the sweat pad and has a length of 7-7.5cm; the horizontal reference line is established at the recess of regions b and d and has a length of 7-7.5cm.

[0050] Preferably, the sweat-absorbing pad is used with left and right sides under the armpits, and the left and right sweat-absorbing pads are mirror-symmetrical.

[0051] Preferably, the underarm pad is connected to the garment by sewing or bonding (in this embodiment, Velcro). The position of the underarm pad is adjusted appropriately according to the looseness of the garment, and the four intersection points formed by the edge of the underarm pad and the seam of the underarm portion of the garment are fixed: For a tight-fitting shirt, after aligning the intersection of the longitudinal and transverse reference lines of the underarm pad with the intersection of the seam of the underarm portion of the garment, the edge of the underarm pad forms four intersection points M, N, P, and Q with the seam of the underarm portion of the garment, and then these four intersection points are sequentially connected to the seam of the underarm portion of the garment; For a loose-fitting shirt, after aligning the intersection of the longitudinal and transverse reference lines of the underarm pad with the intersection of the seam of the underarm portion of the garment, it is then moved 1-2 cm appropriately towards the side and front of the body, forming four new intersection points with the edge of the underarm pad and the seam of the underarm portion of the garment, and these four new intersection points are sequentially connected to the seam of the underarm portion of the garment, without showing stitches on the outside of the garment.

[0052] This invention also provides a method for preparing an underarm antibacterial and sweat-absorbing pad (hereinafter referred to as the method), characterized in that the method includes the following steps:

[0053] Step 1: Prepare a sandwich structure knitted laminated fabric by knitting process to form a sweat-absorbing part; the sweat-absorbing part consists of a sweat-absorbing top layer 11, a sweat-retaining middle layer 12 and a sweat-retaining bottom layer 13 connected from the inside to the outside.

[0054] Step 2: Place the impermeable layer 14 on the outside of the sweat storage bottom layer 13;

[0055] Step 3: Sew a waterproof binding fabric 2 around the outer edge of the sweat-absorbing surface layer 11, the sweat-storing intermediate layer 12, the sweat-storing bottom layer 13, and the waterproof layer 14. Use the waterproof binding fabric 2 to sew and fix the sweat-absorbing surface layer 11, the sweat-storing intermediate layer 12, the sweat-storing bottom layer 13, and the waterproof layer 14 together.

[0056] Preferably, in step 1, the process steps for the sweat-absorbing part are as follows:

[0057] S11, Yarn Arrangement: The yarn used in the sweat-absorbing surface layer 11 is supplied by an odd number of yarn feeders from a machine (preferably a double-sided circular knitting machine, more preferably a double-sided jacquard circular knitting machine, and even more preferably a paddle-type double-sided jacquard circular knitting machine); the yarn used in the sweat-retaining middle layer 12 is supplied by a special yarn feeder for weft yarn, and yarns with antibacterial, moisture-absorbing, and heat-conducting functions are inserted; the yarn used in the sweat-retaining bottom layer 13 is supplied by an even number of yarn feeders from a machine, and yarns of the same material can be inserted according to functional needs;

[0058] Preferably, in step S11, the arrangement and threading methods of short linear loops, long linear loops, elliptical loops, diamond-shaped loops, and continuous hexagonal loops are all the same, as detailed below:

[0059] Yarn threading of the sweat-absorbing surface layer 11: Starting from the first lane (1F), odd-numbered lanes are threaded with alternating hydrophilic and hydrophobic yarns to form horizontal rows of alternating hydrophobic and hydrophilic yarns, utilizing the hydrophilic and hydrophobic properties of the yarns to form a hydrophilic and hydrophobic arrangement on the fabric surface.

[0060] The hydrophilic yarns are cotton yarn, licorice yarn, and artemisia yarn; the hydrophobic yarns are nylon yarn, nylon yarn, and polyester yarn. Nylon yarn, licorice yarn, and artemisia yarn have antibacterial properties, while cotton yarn, nylon yarn, and polyester yarn are the main raw materials for the main absorbent fabric. In the absorbent surface layer 11, yarns containing antibacterial components account for more than 73% of the total number of rows.

[0061] Preferably, the Kanglun yarn used is produced by Shanghai Xingnuo Kanglun Co., Ltd., which features an improved three-dimensional shape of the grooved fiber cross-section, resulting in excellent moisture absorption and quick-drying properties. Non-leaching silver-based antibacterial substances are added to the fiber interior, rapidly killing various bacteria that cause body odor without irritating the skin, maintaining a dry and comfortable environment between the body and clothing. Licorice yarn and cotton yarn can quickly absorb sweat, while polyester and Kanglun yarns have good moisture-wicking properties, and nylon yarn has good thermal conductivity.

[0062] In this embodiment, odd-numbered threads starting from the first thread (1F) are sequentially threaded with a certain number of strands of nylon yarn, cotton yarn, nylon yarn, polyester yarn, and licorice yarn, forming alternating rows of hydrophobic and hydrophilic yarns, such as... Figure 4 As shown;

[0063] The yarn used in the sweat storage interlayer 12 is threaded through the special yarn nozzles of the weft yarn, with the number of yarn nozzles being half of the total number of yarns on the machine. The threaded yarn is a moisture-absorbing and moisture-wicking bulky yarn, which makes the sweat storage interlayer 12 have a certain degree of fluffiness and softness while having the function of moisture absorption and wicking, thus improving wearing comfort.

[0064] Preferably, the moisture-absorbing and moisture-wicking bulky yarn is polyester bulky yarn, and in this embodiment, 600D polyester bulky yarn is used.

[0065] Preferably, while improving moisture absorption, moisture-absorbing and antibacterial yarn (artemisia yarn in this embodiment) is added and threaded at an interval of 2:1 to reduce costs and help improve the antibacterial properties of the main sweat-absorbing fabric; specifically, the yarn is threaded into the special yarn nozzle position of the weft yarn, the number of yarn nozzles is half of the total number of machine threads, and the order of threading the yarn is 1 set of moisture-absorbing and moisture-wicking bulky yarn and 1 set of moisture-absorbing and antibacterial yarn, with a threading ratio of 2:1, and this cycle is repeated.

[0066] The yarn used in the bottom layer 13 of the sweat storage layer: the even-numbered yarns starting from the second line (2F) are all threaded with hydrophilic yarns to absorb and store the sweat transmitted from the middle layer 12 of the sweat storage layer;

[0067] The hydrophilic yarns are cotton yarn, licorice yarn, and artemisia yarn; in this embodiment, 32S cotton yarn is used.

[0068] S12. Knitting: The machine used includes a lower needle cylinder and an upper needle plate;

[0069] The lower needle cylinder knits the sweat-absorbing surface layer 11; the needles of the lower needle cylinder knit in odd-numbered rows, and are arranged in clusters according to different shapes. In some odd-numbered rows, the lower needle cylinder selects needles through a needle selection device to form clusters, and the clustered areas correspond to the perforations on the surface of the sweat-absorbing surface layer 11.

[0070] The needles on the upper needle plate knit in even-numbered rows to form a sweat-retaining bottom layer 13;

[0071] The yarn of the sweat-storing intermediate layer 12 is not involved in the weaving and is inserted between the sweat-absorbing surface layer 11 and the sweat-storing bottom layer 13 by weft insertion to form a sandwich layer;

[0072] The absorbent surface layer 11 and the sweat-storing bottom layer 13 are selected according to different tucked shapes, and the corresponding knitting needles of the lower needle cylinder and upper needle plate are tucked. The knitting needles in the upper needle plate that are aligned with the knitting needles of the lower needle cylinder are also tucked, which serves to connect the absorbent surface layer 11 and the sweat-storing bottom layer 13.

[0073] Preferably, in step S12, the arrangement and weaving process of short linear loops, long linear loops, elliptical loops, diamond-shaped loops, and continuous hexagonal loops is as follows:

[0074] (1) Linear tufting (including short and long linear tufting) arrangement knitting process: For linear tufting patterns, the minimum pattern cycle of the machine includes one or more linear tufting arrangements, each linear tufting arrangement being a linear tufting pattern unit; the arrangement of tufting positions within this linear tufting pattern unit is diverse, and can be distributed at different angles within a 360° range along the lower left to upper right direction and along the lower right to upper left direction; for example, taking the knitting position of any needle on any odd-numbered track as the starting point of the tufting arrangement, the next tufting arrangement point is the knitting position of the needle on the left or right side of the next adjacent odd-numbered track, and these two tufting points form the shortest linear tufting pattern; and so on, continuously on the left or right side of the next adjacent odd-numbered track. The needles on the right lower cylinder knit multiple loops sequentially, forming a gradually increasing long linear loop pattern. If multiple linear loop arrangements are designed in the machine's minimum pattern cycle, the interval between linear loop pattern units should be set reasonably, distributed regularly, and patterns should be avoided from intersecting. The needles on the odd-numbered lower cylinders that are selected for looping loops loop normally, while the needles on the other unselected odd-numbered lower cylinders loop normally. The needles on the odd-numbered needle trays corresponding to the needles on the selected odd-numbered lower cylinders loop loop normally, while the needles on the other unselected odd-numbered needle trays do not knit. The needles on the odd-numbered lower cylinders that are not selected for looping loops knit normally, while the needles on the upper needle tray do not knit. The needles on the even-numbered needle trays that are not selected for looping loops loop normally, while the needles on the even-numbered lower cylinders do not knit.

[0075] (2) Elliptical loop arrangement weaving process: For the elliptical loop arrangement pattern, the minimum pattern cycle of the machine includes one or more elliptical loop arrangements, and each elliptical loop arrangement is an elliptical loop pattern unit; the elliptical loop pattern unit is generally distributed longitudinally or laterally;

[0076] When the elliptical tufted pattern is arranged vertically, the starting point of the tufting arrangement is the knitting position of any needle in any odd-numbered row (e.g., row 1). The next two tufting points are the knitting positions of the needles on the left and right sides of the next adjacent odd-numbered row (e.g., row 3). This pattern is repeated twice, that is, tufting at the knitting positions of the needles on the left and right sides of two odd-numbered rows (e.g., row 7 and row 11) with a interval of 2. The ending point of the last tufting arrangement is the knitting position of the needle in the next adjacent odd-numbered row (e.g., row 13) with the same starting row.

[0077] When the elliptical tucked pattern is horizontally distributed, the starting point of the tucked pattern is any three consecutive needles of the lower cylinder that are spaced one needle apart in any odd-numbered row (e.g., row 1). The next two tucked pattern points are the knitting positions of the needles on the left and right sides of these three needles in the next adjacent odd-numbered row (e.g., row 3). The last three tucked pattern ending points are the knitting positions of the three needles of the lower cylinder in the same starting row in the next adjacent odd-numbered row (e.g., row 5).

[0078] If multiple elliptical tufted patterns are designed in the machine's minimum pattern cycle, the interval between the elliptical tufted patterns should be set reasonably to avoid patterns intersecting; the needles of the odd-numbered needle cylinders below the selected tufted pattern should form tufts, while the needles of the odd-numbered needle cylinders below the unselected tufts should form normal loops; the needles of the odd-numbered needle plate corresponding to the needles of the selected tufted pattern should form tufts, while the needles of the odd-numbered needle plate below the unselected tufts should not knit; the needles of the odd-numbered needle cylinders below the unselected tufts should knit normally, while the needles of the upper needle plate should not knit; the needles of the even-numbered needle plate below the unselected tufts should form normal loops, while the needles of the even-numbered needle cylinders below the unselected tufts should not knit;

[0079] (3) Diamond-shaped tuck arrangement knitting process: For the diamond-shaped tuck arrangement pattern, the minimum pattern cycle of the machine includes one or more diamond-shaped tuck arrangements, and each diamond-shaped tuck arrangement is a diamond-shaped tuck pattern unit; take the knitting position of any needle of any odd-numbered road (such as the first road) as the starting point of the tuck arrangement; the next two tuck arrangement points are the knitting positions of the needles of the two needles of the two needles adjacent to the starting needle of the next adjacent odd-numbered road (such as the third road); the next two tuck arrangement points are the knitting positions of the needles of the two needles of the two needles adjacent to the first two tuck arrangement needles of the next adjacent odd-numbered road (such as the fifth road); and so on, extend the side length of the diamond pattern until the left and right arrangement points at the maximum width in the diamond-shaped tuck arrangement pattern; then, according to the opposite rule from the starting arrangement point to the left and right arrangement points at the maximum width, determine the other half of the tuck arrangement position points of the diamond grid, and complete the knitting of the entire diamond-shaped tuck arrangement pattern;

[0080] If multiple diamond-shaped loop arrangements are designed in the machine's minimum pattern cycle, the interval between the diamond-shaped loops should be set reasonably to avoid overlapping patterns; the needles of the odd-numbered needle cylinders in the selected loops loop normally, while the needles of the odd-numbered needle cylinders in the unselected loops loop normally; the needles of the needle trays on the odd-numbered needles corresponding to the looped needles of the selected loops loop normally, while the needles of the needle trays on the odd-numbered needle cylinders in the unselected loops do not knit; the needles of the odd-numbered needle cylinders in the unselected loops knit normally, while the needle trays on the upper needle trays do not knit; the needles of the needle trays on the even-numbered needle cylinders in the unselected loops loop normally, while the needles of the even-numbered needle cylinders do not knit.

[0081] (4) Continuous Hexagonal Loop Arrangement Knitting Process: For continuous hexagonal loop patterns, the minimum pattern cycle of the machine is generally a single continuous hexagonal loop arrangement. The size of the continuous hexagonal loop arrangement pattern can be varied and adjusted. The starting point of the loop arrangement is the knitting position of two needles at any odd-numbered path with an interval of 2n+1 (n=1,2,3…). Subsequent loop arrangement points are the knitting positions of the two needles at each adjacent odd-numbered path, forming the two lower diagonal sides of a continuous hexagon. The next loop arrangement point is the knitting position of the two needles at the previous loop position at each adjacent odd-numbered path, forming the two lower vertical sides of a continuous hexagon. The knitting positions of the needles on adjacent odd-numbered paths and adjacent outer lower cylinders are knitted in a repeating pattern several times to form the two middle diagonal sides of a continuous hexagon. The subsequent loop arrangement points are the knitting positions of the two needles from the previous loop position on each next odd-numbered path, and this pattern is repeated several times to form the two upper vertical sides of a continuous hexagon. The subsequent loop arrangement points are the knitting positions of the two needles from the previous loop position on each next adjacent odd-numbered path and adjacent inner lower cylinders, and this pattern is repeated several times to form the two upper diagonal sides of a continuous hexagon. This completes a continuous hexagonal loop arrangement unit.

[0082] The needles of the odd-numbered needle cylinders selected for the above-mentioned tufting loop will knit normally, while the needles of the odd-numbered needle cylinders not selected for the above-mentioned tufting loops will knit normally; the needles of the needle trays corresponding to the needles of the odd-numbered needle cylinders selected for the above-mentioned tufting loops will knit normally, while the needles of the needle trays not selected for the above-mentioned tufting loops will not knit; the needles of the odd-numbered needle cylinders not selected for the above-mentioned tufting loops will knit normally, while the needle trays will not knit; the needles of the needle trays not selected for the above-mentioned tufting loops will knit normally, while the needles of the even-numbered needle cylinders will not knit.

[0099] In summary, the underarm pads of the present invention have antibacterial function. The weight of a single product made of different materials is 7-10g. Actual wear tests have shown that the underarm pads of the present invention are skin-friendly and comfortable, do not affect perspiration, and do not cause itching or discomfort. Both shapes of the sweat-absorbing pads are soft and fit the body. The connection method does not require adhesive, does not damage clothing, and is not easy to twist or slip off. In the hot summer, it can absorb a large amount of sweat under the armpits in time. When placed on a slightly loose shirt, it is more conducive to breathability and dryness. In daily wear, there will be no situation where sweat soaks and stains the clothing. It can be washed and reused repeatedly, and still has the anti-leakage effect after washing.

[0101]

[0102] Table 2 Main performance indicators of the impermeable layer 14

[0103]

[0104]

[0105] Testing revealed that when the middle layer of the sweat-absorbing pad consists of alternating layers of polyester bulky yarn and mugwort yarn, the thickness of the absorbent portion is 2.88–3.34 mm, the breathability is 393.08–403.48 mm / s, and the water absorption is 4.25–4.87 times its own weight. When the middle layer of the sweat-absorbing pad is entirely composed of polyester bulky yarn, the thickness of the absorbent portion reaches 4.63 mm, the breathability is 400.64 mm / s, and the water absorption is 6.78 times its own weight. Adding a waterproof fabric to the pad body slightly reduces breathability. However, because the selected polyester fabric is lighter and more breathable, using it as the waterproof layer results in better breathability for the underarm pad.

[0106] Any aspects not covered in this invention are applicable to existing technologies.
