When knitting the sock body of the trouser legs, the lining yarn is replaced with a soluble yarn to replace at least part of the lining yarn, and the sock body is knitted. The inner lining layer of the knitted trouser legs is subjected to a napping treatment to form a plush layer on the surface of the inner lining layer; and then the trouser legs are washed to dissolve the water-soluble yarn in the soluble yarn. The invention uses the soluble yarn to reduce the thickness of the sock body without affecting the napping process and destroying the sock body structure, and effectively improves the warmth retention and comfort of the one-piece knitted pantyhose.

Description

Technical Field

[0001] The present invention relates to the technical field of pantyhose knitting, and more particularly to a knitting process for thick autumn and winter pantyhose and the pantyhose. Background Art

[0002] Pantyhose are garments that tightly wrap the torso from the waist to the feet, mostly worn by women. Most of them are relatively thick and suitable for wearing in cold weather. Therefore, pantyhose are usually woven with a double-layer structure. Some of them look like single layers to us, but in fact they have connecting lines that connect the double layers into an inseparable double layer.

[0003] Traditional pantyhose often use thicker yarns to enhance warmth. However, these yarns are not fine enough, causing wrinkles around the legs. Furthermore, the yarn texture is more pronounced, significantly different from thin stockings. To improve this performance and enhance the look of bare legs, existing pantyhose often use finer yarns for the outer layer and increase the number of stitches to enhance fineness.

[0004] But for autumn and winter tights, too thick soles make people uncomfortable to wear and not fit well, so the knitting soles need a single-layer structure. In actual knitting, the inner and outer layers are knitted synchronously, so some sock factories need to disassemble the soles and cut off the inner soles.

[0005] Some existing solutions to this problem involve disconnecting the connecting thread when knitting the sole, separating the two layers, and then cutting off the inner layer after knitting. While this method can reduce the thickness of the pantyhose on the foot, it creates a noticeable separation on the sole. The outer layer of the pantyhose is relatively thin, and the cut part creates a clear dividing line, which looks unnatural.

[0006] Some solutions also use a yarn reduction device to reduce the yarn content of the foot when knitting the sock body, thereby reducing the thickness of the foot sock body. Although this method can reduce the thickness, it has many problems in actual processing.

[0007] After using a yarn reduction process, the thickness of the leg is reduced. For autumn and winter tights, the inner layer needs to be raised. To avoid damaging the structure of the tights, the only option is to use a sanding process. However, this method has a shorter pile length and limited warmth. If a fleece process is used, the finer yarns are easily damaged. In order to achieve a better bare leg appearance, the warmth performance of the tights is relatively poor.

[0008] In addition, some pantyhose use a spliced ​​sock design, where the sock is knitted separately and then sewn to the trouser legs. This method creates a noticeable seam at the ankle, which reduces the overall fit. Therefore, effectively improving the warmth and comfort of knitted pantyhose is a current challenge. Summary of the Invention

[0009] 1. Technical problem to be solved by the invention

[0010] In view of the deficiency in the prior art that one-piece knitted pantyhose cannot balance warmth retention and fit, the present invention provides a knitting process and pantyhose for thick autumn and winter styles. The knitting process of this scheme reduces the thickness of the sock body without affecting the brushing process or damaging the sock body structure, thereby effectively improving the warmth retention and fit of the one-piece knitted pantyhose.

[0054] In order to further understand the content of the present invention, the present invention is described in detail with reference to the accompanying drawings and embodiments.

[0055] The structures, proportions, sizes, etc. illustrated in the drawings of this specification are only used to match the contents disclosed in the specification for understanding and reading by those familiar with this technology. They are not used to limit the conditions for implementation of the present invention and therefore have no substantial technical significance. Any modification of the structure, change in the proportional relationship, or adjustment of the size should still fall within the scope of the technical content disclosed by the present invention without affecting the efficacy and purpose of the present invention. At the same time, terms such as "upper", "lower", "left", "right", and "middle" quoted in this specification are only for the convenience of description and are not used to limit the scope of implementation. Changes or adjustments in their relative relationships should also be considered as the scope of implementation of the present invention without substantially changing the technical content.

[0056] Existing autumn and winter pantyhose are typically knitted with a spliced ​​body. If knitted in one piece, additional steps are required to adjust the thickness of the body. The existing process, which can be retrieved, reduces the thickness of the body by cutting away the inner layer. However, this creates a sutured bump on the surface of the body, affecting the overall visual appearance. To address this issue, the present application provides a knitting process for knitting pantyhose with the legs and body in one piece. This process reduces the thickness of the body without affecting the integrity of the body and without creating prominent creases.

[0057] Example 1

[0058] Combine Figure 1 The knitting process of a thick autumn and winter pantyhose of this embodiment includes a crotch portion 1 and a trouser leg 2, and the knitting process includes:

[0059] S1. Using a double-sided weaving method, the lining yarn and the face yarn are woven together, the lining yarn forms an inner lining layer, and the face yarn forms a stocking layer, and the leg portion 21 of the trouser leg 2 is woven into one piece.

[0060] The double-sided knitting process can be performed using a small circular knitting machine using an interlocking rib. The face yarn can be made of a fine core-spun yarn or bare spandex, forming the stocking layer. The lining yarn can be made of a yarn material such as spandex, nylon, or polyester, or a covering yarn, forming the inner lining layer. The lining yarn and the face yarn are knitted together, and a connecting yarn is fed simultaneously during the knitting process, connecting the stocking layer and the inner lining layer together to form a composite single-layer structure. If the connecting yarn is knitted only with the lining yarn during double-sided knitting, the stocking layer and the inner lining layer will be separated. In this embodiment, a composite single-layer trouser leg structure is formed.

[0061] In some embodiments, the leg portion may include a thigh and a calf. The radial dimension of the calf is smaller than that of the thigh. During knitting, the radial dimension may be reduced by closing the edges during the knitting process, so that both the thigh and calf can better fit the human leg. Furthermore, preferably, the flat dimension of the calf at the ankle is 1-8 cm smaller than that at the thigh root, typically 1.5-5 cm.

[0062] S2. Knitting the sock body 22 of the trouser leg 2. Replace the lining yarn with soluble yarn to replace at least part of the lining yarn to knit the sock body.

[0063] After knitting the leg portion 21, the sock body 22 needs to be knitted. The knitting method used in step S1 is continued to form a composite single-layer structure. However, to reduce the thickness of the sock body later, some yarns need to be replaced with soluble yarns. In this embodiment, for easier wearing, the lining yarn corresponding to the sole is replaced with soluble yarn, and the soluble yarn is made of water-soluble yarn.

[0064] S3. Brushing the inner lining layer of the knitted trouser legs 2 to form a plush layer on the surface of the inner lining layer.

[0065] To improve warmth, autumn and winter tights are often brushed, creating a fleece layer on the inner surface. The longer the fleece, the better the warmth. Brushing methods include sanding, rubbing, and pulling. Sanding, which uses sandpaper to create the fleece, is inefficient and has a short length, resulting in relatively poor warmth retention. Rubbing and pulling use hooks to create a longer fleece, offering improved warmth. However, brushing or pulling can snag yarn, so the material should be kept at a certain thickness to prevent damage to the finer outer surface yarns.

[0066] S4, washing the trouser legs 2 to dissolve the water-soluble yarn in the soluble yarn.

[0067] After the napping process, the entire trouser leg is raised to form a pile. Then, the entire leg can be washed to dissolve the water-soluble yarn and reduce the thickness of the sock body at the sole of the foot. The washing solution may vary depending on the properties of the water-soluble yarn. You can refer to the solubility characteristics of existing water-soluble yarns to select the right one.

[0068] S5, forming a semi-finished pantyhose product through at least cutting and sewing processes, and then performing a shaping process to form the pantyhose.

[0069] In this embodiment, the trouser legs 2 and the crotch portion 1 are knitted separately. After knitting, the trouser legs are connected together. In order to be assembled with the crotch portion, they need to be cut and then sewn together with the crotch portion and the toe portion is sewn to form a semi-finished pantyhose. After that, it is shaped to form a pantyhose product.

[0070] In this embodiment, the waist opening of the pantyhose is formed on the crotch portion, and can also be knitted independently and spliced ​​with the crotch portion, and reference can be made to the existing methods.

[0071] Example 2

[0072] In this embodiment, the specific process can refer to Example 1. The characteristic is that the soluble yarn and the water-insoluble yarn in this embodiment are composed, and the thickness of the yarn can be selected according to the thickness of the sock body.

[0073] The soluble yarn in this embodiment can be formed by a combination of water-soluble yarn and water-insoluble yarn. The two yarns can be distributed side by side, that is, the two yarns are fed in parallel, or the water-soluble yarn and the water-insoluble yarn can be twisted into a single yarn for feeding, or the water-soluble yarn can be wrapped around the outer periphery of the water-insoluble yarn. The water-soluble yarn can be a thicker yarn, while the water-soluble yarn can be relatively thin.

[0074] In another embodiment, the soluble yarn is composed of coarse yarn and fine yarn, wherein the coarse yarn is water-soluble yarn and the fine yarn is water-insoluble yarn. After washing, the water-soluble yarn dissolves, while the water-insoluble yarn remains on the sock body 22. Since the water-insoluble yarn is a relatively thin yarn, the thickness of the sock can also be reduced.

[0075] Specifically, the water-insoluble yarn may be yarn of other sizes such as 8D, 10D, or 15D, and may be made of materials such as nylon and polyester.

[0076] Example 3

[0077] In this embodiment, the soluble yarn is water-soluble yarn, and a portion of the sock body is a cutout section, such as a circular area corresponding to the sole of the foot, or the entire sock body. The inner lining layer and the stocking layer of the cutout section are woven into a separable structure. That is, during knitting, the connecting yarn is woven together with the inner lining layer, while the face yarn is woven independently to form the stocking layer, thereby separating the two.

[0078] During weaving, the water-soluble yarn is distributed in a ring shape at both ends of the remaining section, that is, the inner lining layer is woven into two rings by the water-soluble yarn. After washing in step S4, the inner lining layer of the remaining section area of ​​the sock body is removed due to the dissolution of the water-soluble yarn, so that the thickness of the sock body 22 is reduced.

[0079] In this embodiment, when knitting the sock, the lining yarn is replaced with water-soluble yarn. After knitting a certain length, the water-soluble yarn is then replaced with other yarns. This is intended to allow the sock's portion, knitted with other yarns, to dissolve and fall out of the sock after washing, reducing the sock's thickness. This method can reduce the overall thickness of the sock. In this embodiment, the connecting yarn can be made of a thinner yarn that can be easily cut. Alternatively, water-soluble yarn can be used in this area, which will dissolve directly after knitting.

[0080] Example 4

[0081] In this embodiment, the soluble yarn is water-soluble yarn, which can partially replace the yarn of the sock body. For example, water-soluble yarn is used at the ankle and heel positions. After dissolution, the thickness at the ankle and heel positions is reduced.

[0082] In other embodiments, the soluble yarn may also be a mixed structure of water-soluble yarn and water-insoluble yarn, and part of the lining yarn is retained after dissolution, which can not only achieve the effect of reducing the thickness but also maintain the connection between the sock body yarns.

[0083] Example 5

[0084] In this embodiment, the soluble yarn is water-soluble yarn. Taking 840 stitches of loop yarn as an example, water-soluble yarn can be used for every 20 stitches and non-water-soluble yarn for every 10 stitches, thereby forming water-soluble yarn distributed at intervals. After dissolution, the local thickness is reduced, and a strip-shaped yarn reduction effect is formed.

[0085] In another embodiment, the soluble yarn is formed by combining water-soluble yarn with spandex, nylon or polyester, and is also in the form of spaced soluble yarns.

[0086] Example 6

[0087] In combination with the above embodiments, as the weaving method of the leg position, at the leg position, the face yarn is independently woven to form a stocking layer, and the connecting yarn and the lining yarn are cooperatively woven into the lining layer, and the stocking layer and the lining layer are separable structures.

[0088] The process is:

[0089] S11. Use a double-sided circular knitting machine to weave, with the upper needle disc weaving the face yarn to form the stocking layer, and the lower needle disc weaving the lining yarn to form the lining layer. The connecting yarn is woven together with the lining yarn and the outer yarn to form the upper connecting part 211, and the connecting part has a composite single-layer structure.

[0090] S12, the upper needle disc stops feeding the connecting yarn, and the face yarn of the upper needle disc is independently woven to form a stocking layer; the lining yarn and the connecting yarn are woven together to form an inner lining layer; the stocking layer and the inner lining layer are separated and woven to the bottom end of the leg.

[0091] When knitting to the bottom of the leg, prepare to knit the sock body, the upper needle disc resumes the feeding of the connecting yarn, the upper needle disc knits the yarn to form the stocking layer, and the original lining yarn is replaced by a mixed yarn of water-soluble yarn and non-use yarn to knit the sock body, and the lower needle disc knits the lining yarn to form the lining layer.

[0092] In this knitting process, soluble yarn is used starting from the connection between the leg 21 and the sock body 22, so that the thickness at the ankle can be reduced without affecting the integrity of the structure and without obvious signs of thickness change.

[0093] Example 7

[0094] In this embodiment of the knitting process for thick autumn and winter pantyhose, during step S1, the leg portion 21 of the pant leg 2 comprises connecting portions 211 at both ends and a central tubular body 212. At the connecting portion 211, the face yarn and lining yarn are woven together, with the connecting yarn connecting the lining yarn and the face yarn together to form a composite single-layer structure. At the tubular body 212, the face yarn is independently woven to form the stocking layer, while the connecting yarn and lining yarn are woven together into the lining layer, creating a separable structure.

[0095] As an example, the specific weaving process of step 1 is:

[0096] S11. Use a double-sided circular knitting machine to weave, with the upper needle disc weaving the face yarn to form the stocking layer, and the lower needle disc weaving the lining yarn to form the lining layer. The connecting yarn is woven together with the lining yarn and the outer yarn to form the upper connecting part 211, and the connecting part has a composite single-layer structure.

[0097] S12, the upper needle disc stops feeding the connecting yarn, and the face yarn of the upper needle disc is independently knitted to form a stocking layer; the lining yarn and the connecting yarn are cooperatively knitted to form an inner lining layer; the stocking layer and the inner lining layer are separated.

[0098] S13. When knitting to the bottom end of the leg, the upper needle disc resumes feeding the connecting yarn, the upper needle disc knits the face yarn to form the stocking layer, and the lower needle disc knits the lining yarn to form the lining layer. The connecting yarn, the lining yarn and the outer yarn cooperate to weave to form the lower connecting part 211.

[0099] Example 8

[0100] In combination with the aforementioned embodiments, in order to achieve better fit between the stocking layer and the inner lining layer, in this embodiment, the horizontal pull value of the stocking layer is greater than the horizontal pull value of the inner lining layer. The difference between the horizontal pull value of the stocking layer and the horizontal pull value of the inner lining layer can be in the range of 5-40 cm, and can also be further controlled to 10-30 cm. If the horizontal pull value of the stocking layer is large, the stocking layer may fold or slip to the ankle and accumulate. If the difference between the horizontal pull values ​​of the stocking layer and the inner lining layer is small, the stocking layer will have a greater constraint on the inner lining, which is prone to internal wrinkles and a bloated feeling. By setting the horizontal pull value of the stocking layer and the horizontal pull value of the inner lining layer within the above range, better fit is achieved. At the same time, the flattening size at the ankle of the calf is 1-8 cm smaller than the flattening size at the base of the thigh. By controlling the flattening size and the horizontal pull size, the fit with the limb is better.

[0101] In addition, the number of stitches in the inner lining layer and the stocking layer in this embodiment is not less than 600, that is, the number of stitches knitted in one loop of yarn on the cross section is 600. Within the same caliber range, the greater the number of stitches, the greater the coil density and the higher the cross-stretch elasticity.

[0102] Existing double-layered, spliced ​​stockings typically use 400-500 stitches for their outer layers. These thin stockings offer excellent light transmission and a smooth feel against the skin. However, for thicker autumn and winter tights, the outer layer fits tightly against the inner lining, making the split loop structure of the inner layer clearly visible when the leg is bent. Furthermore, the inner layer's material strongly absorbs light and lacks surface finishing, resulting in a low gloss. Consequently, existing stockings lack finesse and an unnatural color.

[0103] In this embodiment, the number of stitches used for the inner lining layer and the stocking layer is no less than 600, such as 760, 840, or 900. Specifically, for example, the inner lining layer uses 800 stitches and the stocking layer uses 840 stitches. This increases the stitch density, and combined with the control of the horizontal pull value, achieves better results in terms of both visual appearance and wrinkle resistance.

[0104] Example 9

[0105] In combination with the above embodiments, the lining yarn of the sock body 22 in this embodiment is all made of soluble yarn. Furthermore, the sock body 22 extends to the ankle, and after washing, the thickness of the sock body at the ankle is reduced.

[0106] Autumn and winter stockings are thicker, and in order to achieve a better fit, they are woven with a larger diameter. However, the ankle area is relatively thin, which results in the stockings not fitting well at the ankle, so the thickness at the ankle needs to be reduced.

[0107] The solution in this embodiment has better fit because the thickness at the ankle is also reduced after washing.

[0108] Example 10

[0109] The present embodiment provides a knitting process for thick autumn and winter pantyhose, the pantyhose comprising a crotch portion 1 and a trouser leg 2, and the knitting process includes:

[0110] S1, using a double-sided weaving method, the inner yarn and the face yarn are woven together, the inner yarn forms the inner lining layer, the outer yarn forms the stocking layer, and the leg portion 21 of the trouser leg 2 is woven into one piece;

[0111] S2, knitting the sock body 22 of the trouser leg 2, replacing the lining yarn with a soluble yarn to replace at least part of the lining yarn, and knitting the sock body;

[0112] S3, performing a fleece or napping process on the inner lining layer of the knitted trouser leg 2 to form a fleece layer on the surface of the inner lining layer;

[0113] S4, washing the trouser legs 2 to dissolve the water-soluble yarn;

[0114] S5. At least dyeing and cutting, then sewing the trouser legs 2 and the crotch portion 1 to form a semi-finished pantyhose product, and then performing a shaping process to form the pantyhose.

[0115] The specific implementation of this embodiment can be carried out with reference to the aforementioned implementation methods, or combined with the aforementioned implementation parts.

[0116] Preferably, the present embodiment adopts a fleece processing process to improve the warmth retention of the pantyhose.

[0117] Compared to sanding, fleecing provides a more effective napping process. If the thickness is reduced by reducing the number of yarns, the outer layer of stockings is thinner, and fleecing can easily disrupt the weave, resulting in substandard products. Therefore, sanding is the only option. However, this embodiment uses soluble yarn to replace the lining yarn, which does not significantly reduce the yarn count. Therefore, fleecing does not damage the stocking structure, allowing for normal fleecing. By combining this with a subsequent washing process, a better yarn reduction effect is achieved.

[0118] In general weaving processes, the method of dyeing first and then plucking the wool can be adopted. However, the method of the present invention needs to be washed, so dyeing needs to be performed after washing to avoid affecting the dyeing effect.

[0119] As another embodiment, the yarn may be dyed in advance and then woven, thereby eliminating the need for subsequent dyeing. The lining layer is generally skin-colored, and the stocking layer may be skin-colored or black, without specific limitation.

[0120] Example 11

[0121] In combination with Examples 9 and 10, the leg 21 in this embodiment includes connecting parts 211 at both ends and a tube 212 in the middle; at the connecting part 211, the face yarn and the inner yarn are woven together, and the connecting yarn connects the inner yarn and the face yarn together; at the position of the tube 212, the face yarn is independently woven to form a stocking layer, and the connecting yarn and the inner yarn are woven together into the lining layer, and the stocking layer and the lining layer are separable structures; the connecting part 211 at the top of the tube 212 is sewn and connected to the crotch 1.

[0122] The crotch portion 1 can be a boxer pants structure, a briefs structure, or a fabric structure that only covers the buttocks. To achieve integration with the crotch portion, the connection portion must be cut to a corresponding shape. The crotch portion structure can be applied to other embodiments.

[0123] The connection portion referred to in this application emphasizes the transition from the single-layer portion to the double-layer separation. It can occupy a large area to connect the crotch portion to the tube, or it can simply be a partial structure with a sewn edge. Furthermore, the lower connection portion can also be made of soluble yarn.

[0124] Example 12

[0125] Combine Figure 4 This embodiment provides an example of how to thin the entire sock body in step S2. The knitting process in step S2 is as follows:

[0126] S21. Use water-soluble yarn to replace the connecting yarn and the lining yarn, and weave multiple loops on the top of the sock; this part can fall off in a ring shape in water.

[0127] S22. The water-soluble yarn is replaced with the water-insoluble knitting yarn, and the knitting is continued in a manner of separating the stocking layer and the lining layer.

[0128] S23. At the bottom of the sock, water-soluble yarn is used again to replace the connecting yarn and the lining yarn, and the lining layer and the stocking layer are combined into a single-layer structure to weave multiple circles at the bottom of the sock to form a ring-shaped soluble structure.

[0129] After washing in step S4, the lining yarn and the connecting yarn at both ends of the sock body are dissolved, so that the middle double-layer knitted sock body is disconnected at both ends. Since it is separated from the stocking layer, it can be removed as a whole to reduce the thickness.

[0130] Example 13

[0131] In combination with the above embodiments, the thick autumn and winter pantyhose of this embodiment include a crotch portion 1 and a trouser leg 2 connected to each other, and its specific structure is obtained by processing using the above method, wherein the leg portion 21 of the trouser leg 2 and the sock body 22 are knitted into one piece, and the thickness of at least part of the inner lining layer of the sock body 22 is smaller than the thickness of the trouser leg 21 due to the dissolution of the water-soluble yarn.

[0132] As different types of pantyhose, the sock body 22 can be a one-piece, covered sock structure or a step-on structure with an opening. In the one-piece, covered sock structure, the sock body covers at least the instep and sole of the foot, with the toe section sewn together. In the step-on structure, the sock body has an opening at the bottom for the sole to pass through; the opening at the base of the sock body allows the heel to pass through, thus preventing the pantyhose from retracting.

[0133] In other embodiments, the crotch portion 1 and the trouser legs 2 are integrally knitted and connected, or the crotch portion 1 and the trouser legs 2 are independently knitted and connected by seaming and sewing, without specific limitation.

[0134] It is worth noting that the stitching mentioned in the present invention does not necessarily mean the connection between two parts is sewn separately. It can also be connected by weaving. For example, a woven trouser leg blank can be knitted together with the crotch. Stitching is different from knitting, and requires two independent knitting processes to process the parts separately and then piece them together.

[0135] The above schematically describes the present invention and its embodiments, which is not restrictive. What is shown in the accompanying drawings is only one of the embodiments of the present invention, and the actual structure is not limited thereto. In order to avoid repetition, the repeated contents of each embodiment are omitted, but it cannot be assumed that the corresponding embodiment does not contain the features of other embodiments. The features that cooperate with each other between different embodiments can also be combined with each other. Therefore, if ordinary technicians in this field are inspired by it, without departing from the purpose of the invention, without creatively designing structural methods and embodiments similar to the technical solution, they should all fall within the scope of protection of the present invention.
