Description

Technical Field

[0001] This invention relates to the field of pantyhose knitting technology, and more specifically, to a double-layer pantyhose processing technology and pantyhose. Background Technology

[0002] With the pursuit of fashion, pantyhose is becoming increasingly popular among women. Even in autumn and winter, many people still choose to wear stockings to showcase their beauty. However, due to the lower temperatures in autumn and winter, thicker pantyhose have emerged, making them easier to match with clothing.

[0003] However, the problem is that because autumn and winter pantyhose are thicker, it is difficult to precisely control the color of the knitting material. After the pantyhose is formed, its color tone differs greatly from the human skin tone and is not natural enough, affecting its appearance.

[0004] To address this issue, many pantyhose on the market now use double-layered pantyhose to eliminate color differences. This means the pantyhose sold includes an inner layer of leggings and an outer layer of stockings, worn together. Because the color of the outer stockings is easier to control, it provides a better "bare leg" look. However, this method of directly nesting the two pantyhose layers is cumbersome to put on and take off. When squatting and standing up, the inner and outer pantyhose layers tend to slip, and due to the contraction of the leggings, wrinkles often form in the crotch and leg areas, causing the inner and outer pantyhose to not fit snugly.

[0005] To address this issue, the patent "Composite Double-Layer Slimming Panties" (patent application number: 2021212157663, application date: June 2, 2021) discloses composite double-layer slimming panties, including a pantyhose body. The pantyhose body is made of cotton pantyhose and silk pantyhose worn as an inner and outer layer, respectively. The cotton pantyhose is the inner layer, while the silk pantyhose is the outer layer. The cotton and silk pantyhose are separately knitted and formed, and are bonded together with an adhesive layer. While this solution solves the slippage problem, it is relatively stiff, and the texture between the threads is quite clear, lacking the smooth and delicate feel of traditional pantyhose.

[0006] Patent CN201921642762.6 discloses a double-layered bikini-style cotton mid-calf pants. In this patent, both the waistband and body are made of elastic fabric. The waistband is connected to the top of the body, which has legs with cuffs. The body consists of two layers: an outer layer (a stocking layer) and an inner layer (a thermal layer). Cotton stockings are attached to the cuffs. However, this method has several problems. Because the inner and outer layers are independently woven, it is difficult to accurately control their length and elasticity. The fit between the inner and outer layers is also problematic, and wrinkles in the inner layer easily show through the outer stockings.

[0007] In conclusion, ensuring a snug fit between the inner and outer layers of their autumn / winter pantyhose remains a challenge, both technically and in terms of wearing experience. Summary of the Invention

[0008] 1. The technical problem that the invention aims to solve

[0009] The purpose of this invention is to overcome the problem of poor fit in existing double-layer pantyhose processing techniques, and to provide a processing technology and pantyhose for double-layer pantyhose. This solution improves the processing technology, enabling the pantyhose layer and the lining layer to be woven together as a single unit, resulting in a higher degree of fit.

[0010] 2. Technical Solution

[0011] To achieve the above objectives, the technical solution provided by the present invention is as follows:

[0012] The present invention discloses a double-layer pantyhose manufacturing process, which involves separately knitting the crotch area and two panty legs. The manufacturing process of the panty legs is as follows:

[0013] S1. It is knitted using a double-sided circular weft machine. The upper needle plate knits the face yarn to form the outer layer, and the lower needle plate knits the lining yarn to form the inner layer. The connecting part is formed by the connecting yarn, the lining yarn and the face yarn working together to knit.

[0014] S2. At the leg position, the upper needle plate stops feeding the connecting yarn, and the face yarn of the upper needle plate is knitted independently to form the stocking layer; the lining yarn and the connecting yarn are knitted together to form the inner lining layer; the stocking layer and the inner lining layer are separated.

[0015] S3. At the ankle, the upper needle plate resumes feeding the connecting yarn, the upper needle plate knits the outer yarn to form the outer layer, and the lower needle plate knits the inner yarn to form the inner layer. The ankle is formed by the joint knitting of the connecting yarn, inner yarn and outer yarn.

[0016] The processed crotch and two trouser legs should be brushed, sewn together, and then shaped.

[0017] Furthermore, during the weaving process in step S3, the lining yarn is reduced to decrease the thickness of the pantyhose at the ankle.

[0018] Furthermore, during the weaving process in step S3, the lining yarn is replaced with water-soluble yarn to replace part of the lining yarn; and the pantyhose is washed and the yarn is reduced before setting, so that the thickness of the pantyhose at the ankle is less than the thickness of the leg.

[0019] Furthermore, the number of loop stitches in the pantyhose layer and the lining layer is no less than 700 stitches.

[0020] Furthermore, the crotch area is a fabric blank formed by the joint weaving of connecting yarn, inner yarn, and outer yarn.

[0021] Furthermore, the lining yarn is a double-yarn structure formed by fine yarn and roving, wherein the roving is connected to the connecting yarn.

[0022] Furthermore, by turning up the edges or piecing them together, a waistband is created at the top of the pantyhose.

[0023] Furthermore, the ankle section is woven to form a sock structure or a footstool structure.

[0024] The present invention discloses a double-layer pantyhose manufacturing process, which involves separately knitting the crotch area and two panty legs. The manufacturing process of the panty legs is as follows:

[0025] S1. It is knitted using a double-sided circular weft machine. The upper needle plate knits the face yarn to form the outer layer, and the lower needle plate knits the lining yarn to form the inner layer. The connecting part is formed by the connecting yarn, the lining yarn and the face yarn working together to knit.

[0026] S2. At the leg position, the upper needle plate stops feeding the connecting yarn, and the face yarn of the upper needle plate is knitted independently to form the stocking layer; the lining yarn and the connecting yarn are knitted together to form the inner lining layer; the stocking layer and the inner lining are separated.

[0027] S3. At the ankle, the upper needle plate resumes feeding the connecting yarn, the upper needle plate weaves the outer yarn to form the outer layer, and the lower needle plate weaves the inner yarn to form the inner layer. The connecting yarn, inner yarn and outer yarn are woven together to form a single-layer structure. At the ankle, the inner yarn is replaced with water-soluble yarn to replace part of the inner yarn for weaving.

[0028] The present invention provides a type of pantyhose, which is processed using the aforementioned process. The pantyhose includes a crotch and pantyhose legs that are joined together, and the leg section of the pantyhose leg has a double-layer structure with a separate lining layer and a stocking layer.

[0029] Furthermore, the pantyhose has a T-shaped crotch. During knitting, the upper needle plate is cut into pieces so that the needles of the upper needle plate and the lower needle plate work together to form a connecting part located at the edge of the pantyhose leg. The remaining needles of the upper needle plate are knitted independently to form the pantyhose layer. The front of the pantyhose has a strip seam in the middle, and the back has a V-shaped seam formed by the crotch and the pantyhose leg.

[0030] Furthermore, the difference between the lateral tensile strength of the stocking layer and the lateral tensile strength of the lining layer ranges from 5 to 40 cm.

[0031] Furthermore, the ankle section adopts a sock-like structure with anti-slip protrusions on the sole.

[0032] 3. Beneficial effects

[0033] Compared with the prior art, the technical solution provided by this invention has the following advantages:

[0034] (1) The present invention adopts a double-sided separation knitting method from the thigh to the ankle to form a delicate outer layer and a thick inner layer. The entire pant leg is knitted as one piece without nesting. The subsequent processing method is simpler and more convenient, avoiding the problems of stacking and wrinkling of ordinary nested pantyhose, and improving the fit between the pantyhose layer and the inner lining layer.

[0035] (2) This invention uses a water-soluble yarn process to replace the yarn at the ankle, thus ensuring that the ankle structure is not damaged during the napping process of the trouser leg. The water-soluble yarn is then removed by washing. Compared with the direct yarn reduction process, using water-soluble yarn to reduce thickness does not affect the napping process, and the position of the water-soluble yarn can be set as needed, making the process easy to implement.

[0041] To further understand the content of this invention, a detailed description of the invention will be provided in conjunction with the accompanying drawings and embodiments.

[0042] The structures, proportions, and sizes illustrated in the accompanying drawings are merely for illustrative purposes and to aid those skilled in the art in understanding and reading the invention. They are not intended to limit the scope of the invention and therefore have no substantial technical significance. Any modifications to the structure, changes in proportions, or adjustments to size, without affecting the effectiveness and purpose of the invention, should still fall within the scope of the technical content disclosed herein.

[0043] Existing double-layer pantyhose typically involve knitting the outer pantyhose layer and the inner lining layer separately, then combining them together, and finally attaching them to the crotch and body. This processing method results in pantyhose where the pantyhose layer and the inner lining layer do not fit well together, making them prone to wrinkles. This solution aims to improve upon this.

[0044] Example 1

[0045] This embodiment provides a double-layer pantyhose manufacturing process. Here, "thick" refers to a thickness relative to single-layer summer pantyhose, not necessarily a significant increase in overall thickness. During manufacturing, the crotch area 2 and the two panty legs 1 are knitted separately. The manufacturing process for the panty legs 1 is as follows:

[0046] S1. The double-sided circular weft knitting machine is used. The upper needle plate knits the face yarn to form the outer layer, and the lower needle plate knits the lining yarn to form the inner layer. The connecting yarn, the lining yarn and the face yarn are knitted together to form the connecting part 11.

[0047] S2. At the leg position, the upper needle plate stops feeding the connecting yarn, and the face yarn of the upper needle plate is knitted independently to form the stocking layer; the lining yarn and the connecting yarn are knitted together to form the inner lining layer; the stocking layer and the inner lining layer are separated.

[0048] S3. At the ankle, the upper needle plate resumes feeding the connecting yarn, the upper needle plate knits the outer yarn to form the outer layer, and the lower needle plate knits the inner yarn to form the inner layer. The ankle part 13 is formed by the joint knitting of the connecting yarn, inner yarn and outer yarn.

[0049] The processed crotch area 2 and the two trouser legs 1 should be brushed, sewn together, and shaped.

[0050] The double-sided circular knitting machine used can process double-sided fabric, forming a double rib knit effect and creating an inner and outer double-layer structure. In this embodiment, when processing the trouser leg 1, the upper needle plate knits the outer yarn to form the outer layer, and the lower needle plate knits the inner yarn to form the inner layer. The connecting yarn, the inner yarn, and the outer yarn are knitted together to form the connecting part 11, which is a single-layer structure composed of the inner and outer layers.

[0051] When knitting the leg area, the connecting yarn is knitted together with the lining yarn to form the inner lining layer. At the same time, the upper needle plate knits the opposite yarn independently to form the stocking layer, which is separate from the lining. Because the stocking layer and the lining layer are knitted simultaneously, the efficiency is higher, and the corresponding number of loop stitches is maintained between the two, which can improve the fit between them.

[0052] At the ankle area, the synergistic weaving of the face yarn and connecting yarn is restored, and the inner and outer layers are woven together again to form a composite single-layer structure.

[0053] When knitting double-layered trouser legs, from the connecting section to the leg, the connecting yarn in the yarn feeding device can be controlled by a cylinder to exit from the upper needle plate, allowing the upper needle plate and lower needle cylinder to knit independently, forming separate double-layer structures. When knitting to the ankle, the connecting yarn is pneumatically controlled to return, switching the structure. This cycle is repeated for the trouser leg. The inner layer can be made of skin-colored polyester or nylon, with the material chosen according to the thickness. This independent yarn feeding device is already publicly available on existing circular knitting machines and will not be described in detail here.

[0054] In this embodiment, the crotch section 2 is also independently woven. As a specific implementation method, it also adopts a composite structure of inner and outer layers. The face yarn, lining yarn, and connecting yarn used can be the same as the weaving material of the connecting part of the trouser leg, or other materials can be used for weaving. The crotch section and trouser leg can be pre-treated, such as dyeing or napping, and then sewn together. After high-temperature setting, the finished product is formed.

[0055] Most pantyhose products have a waist opening 3. This waist opening 3 can be sewn to the crotch after knitting, or it can be knitted into an integral structure with the crotch, or it can be formed by sewing the panty leg and crotch together and then turning the edge and sewing them together. Other methods can also be used, and there are no specific restrictions.

[0056] Example 2

[0057] refer to Figure 1 In this embodiment, the crotch of the pantyhose is a triangular crotch, with a waistband 3 at the top. The pantyhose legs are knitted according to the following steps:

[0058] S1. Knitted using a double-sided circular weft knitting machine, the upper needle plate knits the outer yarn to form the outer layer, and the lower needle plate knits the lining yarn to form the inner layer. The connecting yarn, lining yarn, and outer yarn are knitted together to form the connecting part 11. The number of stitches in the loops of the pantyhose layer and the lining layer is about 600.

[0059] like Figure 1 As shown, the connecting part of the trouser leg 1 is higher on the outer side and gradually decreases on the inner side, so that it can match the edge shape of the triangle crotch. The lining yarn can be a double yarn structure formed by fine yarn and coarse yarn, wherein the coarse yarn is connected to the connecting yarn.

[0060] S2. At the leg position, the upper needle plate stops feeding the connecting yarn, and the outer yarn of the upper needle plate is knitted independently to form the stocking layer; the inner yarn and the connecting yarn are knitted together to form the inner lining layer; the stocking layer and the inner lining are separated.

[0061] S3. At the ankle, the upper needle plate resumes feeding the connecting yarn, the upper needle plate knits the outer yarn to form the outer layer, and the lower needle plate knits the inner yarn to form the inner layer. The ankle part 13 is formed by the joint knitting of the connecting yarn, inner yarn and outer yarn.

[0062] Based on the sock's structure, if the sole area is too thick, the fit will be poor. To address this, the sole area is thinned by reducing the yarn thickness compared to the connecting section 11. During knitting, a yarn-reducing device can be used to decrease the amount of yarn in the lining. Specific yarn-reducing devices can be referenced from existing textile yarn-reducing structures and will not be elaborated further.

[0063] In this embodiment, the crotch portion 2 is woven in the same way as the connecting portion 11 to form a composite single-layer structure. Of course, in other embodiments, a jacquard machine can also be used to weave the crotch portion to form a certain pattern.

[0064] There is no restriction on the knitting order of the crotch 2 and the trouser leg 1. After they are knitted independently, they are dyed and then the inner layer is brushed. This can be done by brushing, pulling, or other methods to create a pile, which increases the thickness and warmth of the inner layer.

[0065] Then sew the crotch area 2 and the two trouser legs 1 together, and finally perform a shaping process. The shaping process can be carried out using high-temperature steam shaping.

[0066] Example 3

[0067] As another implementation method, the basic implementation method of this embodiment is the same as that of embodiment 2, with the following improvement:

[0068] During the weaving process in step S3, the lining yarn is replaced with water-soluble yarn to replace part of it. Water-soluble yarn dissolves during washing. Incorporating it into the lining yarn reduces the thickness of the inner layer after weaving through washing, thus reducing the thickness of the ankle area 13. The water-soluble yarn can be woven directly as yarn, or it can be mixed with other yarns or wrapped to form a woven yarn. In this way, after the water-soluble yarn dissolves, other non-water-soluble yarns act as a connector, resulting in better durability. The specific choice depends on the specific situation.

[0069] Combination Figure 3 The ankle section 13 can be divided into the wrist section 131 and the foot section 132. The wrist section 131 corresponds to the area near the ankle, and the double-layered structure changes to a single-layered composite structure at the wrist section. The foot section 132 corresponds to the area on the sole and instep, and the part of the foot section 132 is located on the sole to prevent the pantyhose from shrinking. Figure 3 The foot section 132 has a sock-like structure. In this embodiment, the yarn in the foot section 132 can be changed, which will not cause the double-layer structure to come apart, and will also reduce the thickness.

[0070] In the specific processing, the crotch area 2 and the two trouser legs 1 are brushed, washed, dyed, sewn together, and then shaped.

[0071] Brushing can be a process called brushing or shaving, the purpose of which is to create a nap on the inner layer of pantyhose. Compared to brushing, brushing and shaving achieve a better napping effect, are more comfortable against the skin, and also have better warmth retention. Washing is used to dissolve water-soluble yarns, thereby reducing the thickness of the water-soluble yarns at the ankle area.

[0072] The direct yarn reduction process, due to the reduced thickness at the ankle, may damage the outer layer structure during napping, affecting product quality, or the ankle area may not be napped at all, thus increasing the process difficulty. In contrast, the water-soluble yarn solution, because the yarn amount is not directly reduced, or the reduction is very limited, does not affect the napping process on the trouser legs. After napping, washing achieves the effect of reducing thickness.

[0073] It's worth noting that when using water-soluble yarn, the dyeing process is generally carried out after washing, followed by stitching and shaping. If dyeing is done in advance, the coloring effect will be affected after washing.

[0074] Example 4

[0075] As one implementation method, the number of loop stitches in the pantyhose layer and the lining layer is not less than 700 stitches, for example, controlled within the range of 700-1200 stitches, which can have better elasticity and achieve a better matching effect.

[0076] Existing double-layered stockings typically use a 400-500N stitch count for the outer layer, allowing for better light transmission and a smoother feel against the skin. However, with double-layered pantyhose, the outer layer adheres tightly to the inner lining, especially when the leg is bent. This makes the split stitch structure of the inner layer clearly visible. Because the inner material is highly absorbent and lacks surface finishing, it has a low gloss level, resulting in stockings that are not smooth enough and have an unnatural color.

[0077] In this embodiment, the number of loop stitches in the lining layer and the stocking layer is not less than 700N. For example, the lining layer uses 800 stitches and the stocking layer uses 840 stitches, which increases the loop density. Combined with the control of the horizontal tension value, it achieves a better effect in terms of both appearance and wrinkle resistance.

[0078] In this embodiment, the foot part 132 is an open slip-on structure. The foot part 132 is thinned by reducing the yarn thickness, making it thinner than the connecting part 11. The slip-on structure has openings at the bottom and heel of the sock, allowing it to be stepped on to prevent rebound. To prevent the threads from running, a sewn hem is formed at the opening.

[0079] As another implementation, the entire ankle area 13 can be treated with yarn reduction to reduce its thickness. Yarn reduction can be achieved by reducing the number of yarns, replacing them with finer yarns, or using soluble yarns to reduce the amount of yarn.

[0080] The above embodiments provide further explanation of the ankle portion. The wrist and foot portions included therein do not need to have corresponding stitching structures on the sock body. The wrist and foot portions are mainly used to facilitate the explanation of the sock body structure of the present invention and to distinguish between its single-layer and double-layer portions. The wrist portion does not necessarily have to cover the ankle position. For example, the double-layer structure of the leg portion can extend directly to the upper side of the foot and connect directly with the leg.

[0081] Example 5

[0082] This embodiment provides a knitting process for T-shaped crotch pantyhose. In conjunction with the aforementioned implementation method, during knitting, the needles of the upper needle plate work together with the lower needle plate to form a connecting part 11 located on the upper edge of the panty leg 1. Then, through a block-cutting process, the lower needle plate can be controlled to be layered, retaining the needles used for knitting the edge of the panty leg to continue knitting with the connecting yarn and the face yarn to form a single-layer structure. The remaining part is changed to plain knitting, creating an effect of separating the inner and outer layers, knitting to form the pantyhose layer and the lining layer. When the connecting part is knitted, the block part is reset, the upper needle plate stops feeding the connecting yarn, and the pantyhose layer and the lining layer are knitted in the same way.

[0083] In this embodiment, the woven crotch section 2 is a fabric blank formed by the joint weaving of connecting yarn, inner yarn, and outer yarn, and it is a single-layer composite structure. After weaving and sewing, it is combined... Figure 4 The front of the pantyhose has a strip seam in the middle, and the connecting part forms a T-shaped structure. The back of the pantyhose has a V-shaped seam formed by the crotch 2 and the panty leg 1.

[0084] Example 6

[0085] This embodiment provides a type of pantyhose woven using the processes described above. The pantyhose includes a crotch section 2 and a leg section 1 joined together, with the leg section 12 in the leg section 1 having a double-layer structure consisting of a lining layer and a stocking layer separated.

[0086] In some embodiments, the crotch area may be Figure 2 A flat-angle stop, or it can be Figure 1 The triangle in the middle can also be Figure 3 The shape of the fabric structure on one side is not specifically limited.

[0087] For a better fit, the difference between the lateral stretch value of the stocking layer and the lateral stretch value of the lining layer during weaving should be 5-40cm. It can also be further controlled within 10-30cm. If the lateral stretch value of the stocking layer is too high, it may cause the stocking layer to fold or slip and bunch up at the ankle. If the difference in lateral stretch value between the stocking layer and the lining layer is too small, the stocking layer will restrict the lining layer too much, easily causing internal wrinkles and a bulky feeling. By setting the lateral stretch values ​​of the stocking layer and the lining layer within the above-mentioned range, a better fit is achieved. When measuring the lateral stretch value, i.e., the lateral stretch extension value, the testing method for the lateral stretch value in the Chinese textile industry standard "FZ / T 73001-2016 Socks" can be used as a reference.

[0088] In some embodiments, the foot 132 adopts a sock-like structure with anti-slip protrusions on the sole, which serves both as an anti-slip measure and as a foot massager.

[0089] In addition, water-soluble yarn can be used in part of the sole of the foot, or the entire inner layer of the foot can be made of water-soluble yarn, and the inner layer structure can be removed after washing.

[0090] The connecting portion 11 referred to in this application is not necessarily an independent structure; the emphasis is on highlighting that it is the part where the single-layer section transitions to the double-layer separation. In an integrally woven structure, the edge portion connecting the crotch to the double-layer structure can be considered as the connecting portion, or it can be considered that the connecting portion coincides with the crotch.

[0091] During weaving, the outer layer can use core-spun yarn or bare spandex mixed with other materials, while the inner layer can use skin-colored polyester or nylon, with the materials chosen according to the thickness. When weaving to the leg area, to make the foot fit better, the outer layer can be reduced in width by decreasing stitches. The foot area inside the shoe also uses a double-layer weaving method, achieving a natural and realistic double-layer effect in one go.

[0092] The present invention and its embodiments have been described above illustratively. This description is not restrictive, and the accompanying drawings are only one embodiment of the present invention; the actual structure is not limited to this. To avoid repetition, repeated content in each embodiment has been omitted, but this should not be construed as meaning that the corresponding embodiment does not include features from other embodiments. Features that cooperate with each other in different embodiments can also be combined with each other. Therefore, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the spirit of the present invention, such designs should fall within the protection scope of the present invention.
