Description

Technical Field

[0001] The present invention relates to lower body clothing (such as panties, stockings, tights, leggings, etc.) that at least includes a leg portion covering the legs from the wearer's thigh to the ankle, and particularly to socks with a leg portion designed to make the legs look thinner when worn.

Background Art

[0002] Conventionally, in lower body clothing, it is known to devise the leg portion so that the legs look thinner when worn. For example, Japanese Patent No. 3749655 (Patent Document 1) discloses that in the leg portion of socks, a plurality of sized knitting loops are knitted, a highlight portion is formed by the largest-sized knitting loop, a shadow portion is formed by the smallest knitting loop, and the intermediate portion is knitted to have a natural gradation. Further, Japanese Unexamined Patent Application Publication No. 2021-59823 (Patent Document 2) discloses that the leg portion is divided into four parts in the circumferential direction, the front and back are knitted in plain knitting, and the left and right sides are knitted in mesh knitting to create different visual brightnesses.

Summary of the Invention

Problems to be Solved by the Invention

[0004] In the lower body clothing disclosed in the above-mentioned Patent Document 1 and Patent Document 2, the effect of making the legs look thinner (i.e., the shadow effect) was not sufficient. The present invention aims to provide lower body clothing that provides a sufficient shadow effect while being worn. [Means for solving the problem]

[0005] The present invention achieves the above objective by providing a lower body garment comprising at least a leg portion that covers the wearer's legs from the thigh to the ankle, wherein the leg portion comprises a first region located in the front center and / or back center of the leg, a second region located in the side of the leg, and a third region located between the first region and the second region, wherein the lower body garment is knitted with plating knit of face yarn and back yarn, the back yarn being thicker than the face yarn, and dark-colored dope-dyed yarn being used for the back yarn, the first region being knitted with plain knit consisting of flat knit stitches in which the face yarn and back yarn together form knitted loops, and the second and third regions being composed of flat knit stitches and stitches knitted using tucks or floats, wherein the second region has a larger number of floated or tucked stitches per predetermined number of stitches than the third region. [Effects of the Invention]

[0006] According to the present invention, the lower body garment is knitted using plating knitting with face yarn and back yarn, where the back yarn is thicker than the face yarn, and a dark-colored dope-dyed yarn is used for the back yarn. The first region located in the center of the front and / or center of the back of the leg is knitted using plain knitting, where the face yarn and back yarn together form stitch loops. The second region located on the side of the leg and the third region located between the first and second regions are composed of stitches knitted using plain knitting and tucks or floats. In plain knitting, the face yarn and back yarn overlap, so the back yarn is not very visible from the front. However, in stitches knitted using tucks or floats, the overlap of the face yarn and back yarn is shifted, and the back yarn, which may be a dark-colored dope-dyed yarn, is visible from the front. As a result, the areas of stitches knitted using tucks or floats appear darker from the front. The second region has more floating or tucked stitches per unit number of stitches than the third region, so the second region appears darker from the front than the third region. The first region, which consists entirely of plain stitches, appears the brightest from the front. Therefore, when viewed from the front, the leg portion of lower body clothing has a first region that corresponds to the center of the front and / or center of the back of the leg, which is bright; a second region that corresponds to the side of the leg, which is a dark shadow region; and a third region that is located between the first and second regions, which is a light shadow region. Thus, in this invention, the synergistic effect of making the back yarn thicker than the face yarn, performing plating knitting, using a dark-colored dope-dyed yarn for the back yarn, and creating a special structure for the knitted fabric allows for a shadow effect that makes the legs appear slimmer when wearing lower body clothing.

[0008] The present invention will be described in detail below based on the embodiments shown in the drawings. The lower body garment of the present invention comprises at least a leg portion 1 that covers the wearer's legs from the thigh to the ankle, and the embodiment in Figure 1 shows tights having a pant portion. As shown in Figures 1 to 3, the leg portion 1 comprises a first region 11 located in the center of the front and / or center of the back of the leg when worn, a second region 12 located on the side of the leg, and a third region 13 located between the first region 11 and the second region 12.

[0009] The lower body garment of the present invention is knitted using a plating knitting technique with face yarn Y1 and back yarn Y2. In conventional plating knitting, the face yarn is thicker than the back yarn, but in the present invention, the back yarn Y2 is thicker than the face yarn Y1. The face yarn Y1 is not particularly limited, but for example, nylon yarn, polyester yarn, etc., can be used. The face yarn Y1 may also be dyed in a post-knitting process. Dark-colored dope-dyed yarn is used for the backing yarn Y2. Dark-colored dope-dyed yarn can be obtained, for example, by melt-spinning resin pellets mixed with pigment. Examples of pigments for the original yarn include organic pigments such as phthalocyanine-based, anthraquinone-based, and perinone-based pigments, and inorganic pigments such as titanium oxide, iron oxide, ultramarine, and carbon black. In the present invention, yarns colored in dark colors such as dark blue or black original yarns are used. The back yarn Y2 is preferably one in which a polyurethane yarn is used as a core yarn and a dark-colored original yarn is used as a covering yarn. This covering yarn may be a dark-colored original filament yarn or a dark-colored original staple yarn.

[0010] The circumferential widths of the first region 11, the second region 12, and the third region 13 are not particularly limited. The widths of the front (front) center and the back (rear) center of the first region 11 may be the same or different. Also, the first region 11 may not be present at the back center. Assuming that each region has the width as shown in FIG. 1, for example, when the number of needles of the knitting machine in one circumference is 320, the two first regions 11 are each knitted with 57 needles, the two second regions 12 are each knitted with 73 needles, and the four third regions 13 are each knitted with 15 needles.

[0011] The first region 11 is knitted in a plain weave consisting of plain stitches in which the surface yarn Y1 and the back yarn Y2 form stitch loops together. The second region 12 and the third region 13 are composed of stitches knitted using plain stitches and tucks or floats, and the second region 12 has more tucks or tacked stitches per predetermined number of stitches than the third region 13.

[0012] FIG. 4 is a texture diagram showing the knitted fabric of the first region 11 in the present invention in stitch symbols, and one white square represents one plain stitch in which the surface yarn Y1 and the back yarn Y2 form stitch loops together. FIG. 5 is a texture diagram showing an example of the knitted fabric of the second region 12 in the present invention in stitch symbols, where white squares represent plain stitches and black squares represent tack stitches. In the texture diagram of FIG. 5, it is 8 stitches in 2 courses × 4 wales with 1 repeat, and there are 2 tack stitches in 1 repeat. In the 16 stitches of the 4 courses × 4 wales shown in FIG. 5, there are 4 tack stitches in 16 stitches. Figure 6 is a structural diagram showing an example of the knitted fabric of the third region 13 in the present invention, represented by stitch symbols. White squares represent plain knit stitches, and black squares represent tuck stitches. In the structural diagram of Figure 6, there are 64 stitches in 8 courses x 8 wales, and there are 12 tuck stitches in one repeat. Numerous tuck stitches are arranged in the second region 12 and the third region 13, but the number of tuck stitches per predetermined number of stitches is greater in the second region 12 than in the third region 13. For example, according to the embodiments shown in Figures 5 and 6, for every 64 stitches, there are 16 tuck stitches in the knit structure of the second region 12 shown in Figure 5, and 12 tuck stitches in the knit structure of the third region 13 shown in Figure 6. In these illustrated embodiments, the number of tuck stitches per predetermined number of stitches is greater in the second region 12 than in the third region 13. Note that the arrangement of tuck stitches is not limited to the illustrated embodiments. Also, the value of the predetermined number of stitches is not particularly limited as long as the number of stitches being compared between the second region 12 and the third region 13 is the same.

[0013] In Figures 5 and 6, the black squares are explained as tuck stitches, but other stitches knitted using tuck or float stitches may also be used. That is, instead of ordinary tuck stitches, special tuck stitches developed in this invention (described in detail later), spiral stitches, or float stitches may be used. In this case as well, the second and third regions are arranged with a large number of special tuck stitches, spiral stitches, or float stitches, and the number of these stitches per predetermined number of stitches is greater in the second region than in the third region.

[0014] Figure 7(a) is an explanatory diagram showing ordinary tuck knitting using the knitting yarns (face yarn Y1 and back yarn Y2) used in the present invention, and Figure 7(b) is its structural diagram. In Figure 7(a), face yarn Y1 is represented by a thin line, and back yarn Y2 is represented by a thick line. In a tucked stitch, in a wale W2 where the face yarn Y1 and purl yarn Y2 are tucked together, the face yarn Y13 and purl yarn Y23 of the next course C3 following the tucked course C2 are knitted together with the tucked face yarn Y12 and purl yarn Y22 of the previous course C2 to form a stitch loop. In the explanatory diagrams shown in Figures 7(a) and (b), the stitches of wale W1 and wale W3 are plain stitches.

[0015] Figure 8(a) is an explanatory diagram showing the special tuck knit of the present invention using the knitting yarns (face yarn Y1 and back yarn Y2) used in the present invention, and Figure 8(b) is its structural diagram. In Figure 8(a), face yarn Y1 is represented by a thin line, and back yarn Y2 is represented by a thick line. In the special tucked stitch of the present invention, in a wale W2 in which the face yarn Y1 and back yarn Y2 are tucked together, the face yarn Y13 of the next course C3 after the tucked course C2 is floated, and the back yarn Y23 is knitted together with the tucked face yarn Y12 and back yarn Y22 of the previous course C2 to form a stitch loop. In the special tack shown in Figure 8, the face yarn Y13 and back yarn Y23 of course C3 move differently. That is, the face yarn Y13 is floated and the back yarn Y23 is knitted, which is represented by the X-shaped grid in Figure 8(b). In addition, in the ordinary tuck shown in Figure 7, in the knit of course C3 in wale W2, the face yarn Y13 and back yarn Y23 of course C3 are knitted together in a plating state. Comparing the stitches of a normal tuck shown in Figure 7 with the stitches of the special tuck of the present invention shown in Figure 8, the special tuck stitch of the present invention shows more of the back yarn Y2, which uses dark-colored dope-dyed yarn, visible from the front side.

[0016] Figure 9(a) is an explanatory diagram showing spiral knitting using the knitting yarns (face yarn Y1 and back yarn Y2) used in the present invention, and Figure 9(b) is a diagram of its structure. In Figure 9(a), face yarn Y1 is represented by a thin line, and back yarn Y2 is represented by a thick line. In spiral knitting, the face yarn Y1 floats while the back yarn Y2 is knitted to form a stitch loop. In Figure 9, in courses C1 and C2, the face yarn Y1 and back yarn Y2 overlap to form a plain knit, while in course C3, at the wale W2, the face yarn Y1 floats while the back yarn Y2 is knitted. This is represented by the "x" marks in Figure 9(b).

[0017] Figure 10(a) is an explanatory diagram showing float knitting using the knitting yarns (face yarn Y1 and back yarn Y2) used in the present invention, and Figure 10(b) is its structural diagram. In Figure 10(a), face yarn Y1 is represented by a thin line, and back yarn Y2 is represented by a thick line. In a float stitch, the face yarn Y1 and purl yarn Y2 float together, and at the wale W2 of the floating area, the face yarn Y11 and purl yarn Y21 of course C1 preceding the floating course C2 are knitted together in the floating course C2 to form a stitch loop. This is represented by the squares marked with a dash in Figure 10.

[0018] When comparing the visibility of the reverse yarn Y2 from the front side in tuck stitches, special tuck stitches, spiral stitches, and float stitches, the darker reverse yarn Y2 is visible in the order of special tuck stitches > tuck stitches > spiral stitches > float stitches. In other words, for the same number of stitches, the shadow effect is greatest in this order. In the leg portion 1 of a single lower body garment, stitches knitted using tucks or floats other than plain knits may be of the same type, or multiple types of stitches may be used. Furthermore, the second region only needs to have more floated or tucked stitches per predetermined number of stitches than the third region, and the number of these stitches can be increased or decreased to take into account the shadow effect.

[0019] Figures 11 to 13 are micrographs of one embodiment of the knitted fabric of the leg portion of the lower body garment of the present invention. Figure 11 is a micrograph of the first region 11, Figure 12 is a micrograph of the second region 12, and Figure 13 is a micrograph of the third region 13. The fabric was knitted using a plating knit technique, with the face yarn Y1 being a processed nylon yarn (30 denier, 24 filaments) and the back yarn Y2 being a yarn with a 20 denier polyurethane core covered with a black solution-dyed nylon yarn (40 denier, 36 filaments). The knitting structure is shown in Figures 4 to 6, where the black square areas are knitted using the special tuck knit of the present invention instead of the standard tuck knit. In the microscopic images in Figures 11-13, the white threads are surface threads, and the black threads are under-threads. Comparing these images, in Figure 11, the black under-threads are almost completely hidden by the surface threads, but in Figure 12, the black under-threads are exposed on the surface and appear dark. Figure 13 is somewhere between Figure 11 and Figure 12, with fewer black under-threads than in Figure 12, but still visible from the surface. Thus, when the lower body garment of the present invention is worn, it appears bright when viewed from the front, with dark shadows on both sides due to the black lining threads that appear, and a light shadow in between, creating a gradient effect that feels natural and comfortable to wear. The knitted fabrics shown in the micrographs in Figures 11-13 are from immediately after knitting; the white-looking face yarns may be dyed in subsequent processes, for example, beige. Since dark-colored dope-dyed yarn is used for the back yarn, the shadow effect will not be lost even if it is dyed.

[0020] Furthermore, in the embodiment, the fabric was divided into three regions: a first region 11, a second region 12, and a third region 13 between the two regions. However, the intermediate third region 13 could be further subdivided, for example, into a first third region, a second third region, and a third third region. The number of tucked or floated stitches could then be increased from the third region closer to the first region 11 to the third region closer to the second region 12, so that the shadow gradually becomes darker.
