Description

[Technical Field]

[0001] The present invention relates to a circular knitted fabric, and more particularly to a circular knitted fabric suitable for stockings and innerwear. [Background technology]

[0002] In recent years, from the viewpoints of fashion and functionality, there has been a demand for clothing made of circular knitted fabrics, such as stockings and innerwear, to partially vary the thickness of the circular knitted fabric to make it thinner so that it looks closer to bare skin or to have a different texture. However, knitting the entire garment from a thin circular knitted fabric and layering another knitted fabric to partially vary the thickness of the circular knitted fabric or to mix fabrics with different textures is problematic in terms of cost, strength, and durability. For this reason, various efforts have been made to freely knit circular knitted fabrics of different thicknesses depending on the fashion and functionality of the garment.

[0003] For example, Patent Document 1 discloses the following about socks, aiming to provide socks that combine the advantages of both socks and stockings: "The socks are composed of a first section made of natural fibers or chemical fibers alone or a blend of natural fibers and chemical fibers, which covers the sole of the foot from the toes to the heel, and a second section made of chemical fibers and connected to the upper side of the first section, which covers at least up to the ankle."

[0004] [Patent Document 1] Registered Utility Model No. 3225693 Summary of the Invention [Problem to be solved by the invention]

[0005] Patent Document 1 envisions connecting a stocking-style second section above a sock-style first section by knitting them with different yarns, but does not disclose a specific configuration for connecting the first and second sections. As a result, it is unclear how the yarns of the first and second sections are connected, and there is a risk of holes appearing in the section where the yarns are changed.

[0006] Therefore, the object of this invention is to provide a technology for seamlessly connecting circular knitted fabric portions of different thicknesses and textures. [Means for solving the problem]

[0007] In order to solve the above problems, one representative circular knitted fabric of the present invention is a circular knitted fabric comprising a first region and a second region containing a different type of yarn or a different thickness of yarn than that contained in the first region, and a third region of tuck knitting or float knitting between the first region and the second region, in which at least one type or thickness of yarn contained in the first region is switched to a different type or thickness of yarn contained in the second region in the same course. [Effects of the Invention]

[0008] According to the present invention, it is possible to provide a technology for seamlessly connecting circular knitted fabric portions of different thicknesses and textures. Problems, configurations, and effects other than those described above will become apparent from the following description of the preferred embodiments of the invention.

[0010] Hereinafter, an embodiment of the present invention will be described with reference to the drawings.

[0011] In the drawings, the same parts are denoted by the same reference numerals. Furthermore, the position, size, shape, range, etc. of each component shown in the drawings may not represent the actual position, size, shape, range, etc., in order to facilitate understanding of the present invention. Therefore, the present invention is not necessarily limited to the position, size, shape, range, etc. disclosed in the drawings.

[0012] In the description of the specification, terms such as "first," "second," and "third" are used to describe various components, but the components should not be limited by these terms and are used only to distinguish one component from another.

[0013] (Circular knitting 1) A circular knitted fabric 1 of this embodiment will be described with reference to Figs.

[0014] Fig. 1 is a diagram showing a circular knitted fabric 1 of this embodiment. Fig. 1(a) shows an overview of the circular knitted fabric 1, and Fig. 1(b) shows an enlarged view of a main part of the circular knitted fabric 1. As shown in Fig. 1, the circular knitted fabric 1 has a first region 10 and a second region 20, and also has a third region 30 between the first region 10 and the second region 20.

[0015] In this embodiment, the first region 10 is made of a zokki of SCY (single covering yarn), and the second region 20 is made of a cross-knit of NY (nylon yarn) and SCY. As a result, the thickness of the knitted fabric in the second region 20 is thinner than that of the knitted fabric in the first region 10. In addition, in the third region 30, the yarn of the first region is switched to the yarn of the second region in the same course (stitches in the left and right width direction in Figure 1). The third region 30 uses tuck knitting or the like to prevent the switched yarn from coming loose and connects the first region 10 and the second region 20.

[0016] Next, the configuration of each region will be described. In this embodiment, each region is knitted by a knitting machine (not shown) with four yarn feeders (1F to 4F), and four courses of yarn are fed from 1F to 4F when the knitting machine makes one rotation. Hereinafter, the yarns fed from 1F to 4F will be referred to as 1F yarn, etc.

[0017] Figure 2 is a schematic diagram of the first region 10 of the circular knitted fabric 1 of this embodiment. As shown in Figure 2, the knitting structure of the first region 10 is a knit. This is made of a zocki knit, and the 1F yarn to 4F yarn in the figure are all the same SCY.

[0018] Figure 3 is a schematic diagram of the second region 20 of the circular knitted fabric 1 of this embodiment. As shown in Figure 3, the knitting structure of the second region 20 is a knit. This is configured as a cross knit, and the 1F yarn and 3F yarn in the figure are SCY, the same as in the first region, and the 2F yarn and 4F yarn are NY.

[0019] Figure 4 is a schematic diagram of the third region 30 of the circular knitted fabric 1 of this embodiment. As shown within the dashed line in Figure 4, the knitting structure of the third region 30 is tuck knitting. This is configured as a cross knit, and the 1F yarn and 3F yarn in the figure are both the same SCY as the first region 10, and the 2F yarn and 4F yarn are both two yarns in which the same SCY as the first region 10 and the same NY as the second region 20 overlap.

[0020] Looking at this from the perspective of the knitting process of the circular knitted fabric 1, in the first region 10, SCY is fed from 1F to 4F, but at the end of the third region 30 on the first region 10 side, NY is additionally (superimposed on) SCY fed from 2F and 4F. As a result, in the third region 30, the 1F yarn and the 3F yarn are both SCY, and the 2F yarn and the 4F yarn are both SCY+NY. Then, at the end of the third region 30 on the second region 20 side, the feeding of SCY from 2F and 4F is stopped, and only NY is fed. As a result, in the second region 20, the 1F yarn and the 3F yarn are both SCY, and the 2F yarn and the 4F yarn are both NY.

[0021] In this way, in the third region 30, the 2F yarn and the 4F yarn are switched from the yarn of the first region 10 to the yarn of the second region in the same course. The reason for forming the third region 30 using tuck knitting is to prevent the switched yarn from slipping out by hooking the yarn one level higher than the 2F yarn and the 4F yarn and knitting the two together. Furthermore, by using tuck knitting in the third region, the circular knitted fabric 1 is suitable for clothing that requires stretchability.

[0022] The stitch length in the wale direction of the third region 30 (width in the left-right direction in Fig. 4) is 4 stitches in the schematic diagram of Fig. 5, but in reality it is approximately 1 to 50 stitches. However, although a smaller stitch length looks better, if it is too small there is a risk that the yarn switched in the third region 30 will come loose, so it is preferably 10 to 30 stitches.

[0023] Figure 5 is a schematic diagram of a modified example of the third region 30 of the circular knitted fabric 1 of this embodiment. As shown within the dashed line in Figure 5, in this modified example, the knitting structure of the third region 30 is float knit. This is configured as a cross knit like the third region 30 in Figure 4, and the 1F yarn and 3F yarn in the figure are both the same SCY as the first region 10, and the 2F yarn and 4F yarn are both two yarns in which the same SCY as the first region 10 and the same NY as the second region 20 overlap.

[0024] In this modified example, the 2F yarn and the 4F yarn are switched from the yarn of the first region 10 to the yarn of the second region in the same course. The reason for constructing the third region using float knitting is to prevent the switched yarn from slipping out by not feeding the knitting yarn every other wale for the 1F yarn and the 3F yarn and not creating stitches. The float knitting of Figure 5 may be slightly less effective at preventing the switched yarn from slipping out than the tuck knitting of Figure 4, but it is fully applicable to clothing such as socks, which generally use thick yarns.

[0025] According to this embodiment, the SCY of the 2F yarn and 4F yarn among the yarns constituting the first region 10 is switched to NY in the third region 30, and the second region 20 is composed of NY and SCY, so that the thickness of the knitted fabric in the second region 20 can be made thinner than the thickness of the knitted fabric in the first region 10. In this case, by making the third region 30 a tuck knit or float knit, the NY and SCY of the 2F yarn and 4F yarn switched in the third region 30 do not come loose, and holes are prevented from being created in the circular knitted fabric even when the yarns are switched in the same course.

[0026] (Example of applying this invention to stockings) Next, with reference to Figures 6 to 8, an example in which the present invention is applied to stockings 2 will be described. In this example, the circular knitted fabric of the present invention is used in three parts of the stockings 2: the foot part 40, the panty part 50, and the leg part 60.

[0027] 6 is a diagram showing an example in which the circular knit fabric of the present invention is used in the foot part 40 of stockings 2. In this example, the part 41 corresponding to the instep of foot part 40 is made of knitted SCY zocchi, and the part 42 corresponding to the sole of foot part 40 is made of knitted SCY and cotton yarn interlaced. The boundary part 43 between the part 41 corresponding to the instep and the part 42 corresponding to the sole is a tuck knit joining region, where some of the yarns in the part 41 corresponding to the instep, for example, the SCY of the 2F yarn and 4F yarn, are switched to the cotton yarn in the part 42 corresponding to the sole.

[0028] This allows the portion 42 corresponding to the sole of the foot portion 40 of the stocking 2 to be thinner than the portion 41 corresponding to the instep, making it possible to prevent the soles of the feet from getting sweaty.

[0029] Conversely to this example, the portion 41 corresponding to the upper part may be made of a mixed knit of SCY and cotton yarn, and the portion 42 corresponding to the sole part may be made of SCY zokki.

[0030] This allows the part 41 corresponding to the instep of the foot part 40 of the stocking 2 to be thinner than the part 42 corresponding to the sole, so that the part visible from the outside when wearing pumps or the like can be made to look more like bare skin while ensuring the strength of the foot part 40.

[0031] 7 is a diagram showing an example in which the circular knit fabric of the present invention is used for the panty part 50 of stockings 2. In this example, the part 51 corresponding to the waist area adjacent to the buttocks of the panty part 50 is made of a knitted SCY and NY mixed knit, and the part 52 corresponding to the buttocks is made of a knitted NY zocchi. The boundary part 53 between the part 51 corresponding to the waist area adjacent to the buttocks and the part 52 corresponding to the buttocks is a joining region of tuck knitting, and some of the yarns in the part 51 corresponding to the waist area adjacent to the buttocks, for example, the SCY of the 2F yarn and 4F yarn, are switched to NY in the part 52 corresponding to the buttocks.

[0032] As a result, in the panty part 50 of the stockings 2, the part 52 corresponding to the buttocks is made of NY zokki, which makes it thinner than the part 51 corresponding to the waist area adjacent to the buttocks and allows it to have a three-dimensional shape, and since no polyurethane is used, stretching is reduced, making it possible to prevent the panty part from slipping down.

[0033] 8 is a diagram showing an example in which the circular knit fabric of the present invention is used in the leg portion 60 of a stocking 2. In this example, the portion 61 corresponding to the thigh area adjacent to the groin of the leg portion 60 is made of a knitted SCY and NY interlace, and the portion 62 corresponding to the groin area is made of a knitted cotton yarn and NY interlace. The boundary portion 63 between the portion 61 corresponding to the thigh area adjacent to the groin area and the portion 62 corresponding to the groin area is a tuck knit joining region, where some of the yarns in the portion 61 corresponding to the thigh area adjacent to the groin area, for example, the SCY of the 2F yarn and 4F yarn, are switched to the cotton yarn in the portion 62 corresponding to the groin area.

[0034] As a result, in the leg part 60 of the stockings 2, by changing the material of the part 62 corresponding to the groin area from the part 61 corresponding to the thigh area adjacent to the groin area (by not using polyurethane), it is possible to reduce stretching, thereby reducing the feeling of tightness around the groin area.

[0035] (Example of applying this invention to innerwear) Next, an example in which the present invention is applied to innerwear 3 will be described with reference to FIG.

[0036] 9 is a diagram showing an example in which the circular knit fabric of the present invention is applied to innerwear 3. In this example, a front body portion 71 of the innerwear 3 is made of knitted SCY zocki, and a portion 72 corresponding to the side seam is made of knitted SCY and NY interlaced knit. A boundary portion 73 between the front body portion 71 and the portion 72 corresponding to the side seam is a tuck knit joining region, where some of the yarns in the front body portion 71, for example, the SCY of the 2F yarn and 4F yarn, are switched to NY in the portion 72 corresponding to the side seam.

[0037] As a result, in the innerwear 3, the portions 72 corresponding to the side seams can be made thinner than the portions 71 of the front body, and therefore the portions 72 corresponding to the side seams can be made of, for example, mesh fabric, thereby improving breathability.

[0038] (Variation) Although the embodiments of the present invention have been described above, the present invention is not limited to the above-described embodiments, and various modifications are possible within the scope of the present invention.

[0039] For example, in this embodiment, the thickness of the knitted fabric in the first region 10 is different from the thickness of the knitted fabric in the second region 20, but this is not limited to this, and the texture of the knitted fabric in the first region 10 may be made different from the texture of the knitted fabric in the second region 20 by switching the yarn in the third region 30.

[0040] In addition, in this embodiment, the circular knitted fabric 1 is knitted using a knitting machine with four yarn feeders, and each region is knitted using 1F yarn to 4F yarn, but this is not limited to this, and for example, it may be knitted using a knitting machine with eight yarn feeders, and each region may be knitted using 1F yarn to 8F yarn.

[0041] In this embodiment, two of the four yarns, 1F to 4F, namely, 2F and 4F yarns, are switched in the third region 30, but this is not limited to this. In the third region 30, it is sufficient to switch the type or thickness of at least one of the yarns in the first region 10 and the second region 20.

[0042] In this embodiment, the yarns constituting the first region 10 and the second region are SCY, NY, or cotton yarns, but are not limited to these. Various types of yarns can be used for each region, such as yarns made of chemical fibers (polyester, acrylic, polyurethane, etc.), yarns made of natural fibers (cotton, linen, silk, etc.), and DCY (double covering yarn). The yarns switched between the first region 10 and the second region 20 may be the same type but different in thickness.
