Description

  The present invention relates to a lower body garment made of a cylindrical warp knitted fabric that is partially knitted into a cylindrical shape by a warp knitting machine having two rows of needle beds, and a method for manufacturing the same.

  In recent years, pants and shorts that have good fit to the body as clothing consisting of a cylindrical warp knitted fabric knitted by a warp knitting machine such as a double raschel machine having two rows of needle beds and two rows of jacquard guide bars Many items such as girdle, shirt and outerwear have been developed. Recently, many functional products have been developed to improve body shape and improve muscle support function (improvement of tightening force) by using elastic yarn for knitting yarn of clothing and utilizing its expansion and contraction effect.

  Such products use so-called covering yarns in which polyurethane yarns (elastic yarns) are covered with polyester yarns or nylon yarns for knitting yarns guided by two rows of jacquard guide bars. Various functional requirements can be met by using polyester yarn and various processed yarns.

  For example, in the case of pants having a crotch part, for the swelling of the hip part, the length and shape of each part is adjusted by statistical data according to the size of the opening when knitting into a cylindrical shape, elastic yarn etc. It is knitted so that it can be adjusted by using a stretchable material.

  However, in the case of such pants, the length from the upper abdomen of the front body to the crotch depends on the individual body shape of the wearer, that is, the way the muscles and fat are attached, the size, length, shape, etc. There was a difference in the length from the upper hip part of the back body to the crotch part, and it was difficult to create a product that fits each body shape.

  For such a problem, for example, in Patent Document 1, in shorts integrally knitted by a double needle row warp knitting machine, a left half portion including a left side portion of a trunk portion and a left side leg portion in one of the front and rear needle rows is changed to the other side. In the needle row, the right half part consisting of the right side of the trunk and the right leg is knitted, and the left side of the trunk and the right side of the trunk are connected to the front and back of the trunk to form a cylinder, and the left leg and the right side are knitted. Legs are knitted separately and continuously cut from the ends of the front and back knitted parts, and at least one of the front and rear cut edges enters the knitted fabric from the continuous knitted part. In addition, a method is disclosed in which the front and rear portions of the crotch portion have a space by sewing the cut edge inside the leg portion.

  However, with this method, the shape and length of the front and back crotch parts of the front body and back body are the same, and when worn, the lower part of the hip part on the back body side is moved by bending, stretching and stretching movements of the body. It may be pulled in the direction and fall down, and a satisfactory wearing feeling cannot be obtained.

  In view of such a situation, clothing made of a tubular warp knitted fabric that has a good fit and is difficult to give a feeling of cramping (compression) or a feeling of tension to the whole or a part of the body movement (exercise) is required. ing.

It is a schematic explanatory drawing of the principal part of the warp knitting machine used for the knitting of the lower body clothing of the present invention. It is the schematic plan view which shows the pattern on the organization of the clothing for lower body of the Example of this invention. It is a schematic front view after sewing of the clothing for lower body same as the above. It is a knitting organization example of the knitted fabric used for this invention. It is an example of the knitting structure for knitting a cylindrical part in this invention.

  Hereinafter, the lower body garment made of the tubular warp knitted fabric of the present invention and the manufacturing method thereof will be described in detail with reference to the embodiments shown in the drawings.

  Examples of the lower body garment made of the tubular warp knitted fabric of the present invention include lower body garments having a crotch part such as trousers, leggings, pants, shorts, girdle, etc. As will be described later, two rows of needles shown in FIG. A warp knitting machine having a floor, preferably a warp knitting machine having two rows of jacquard guide bars controlled by a jacquard mechanism, is knitted in the pattern of FIG.

  FIG. 2 shows a set of product patterns on the knitting of the lower body garment 1 such as the pants shown in FIG. This pattern is a pattern in which the left body part 10 and the right body part 20 made of a tubular warp knitted fabric are viewed from the front, respectively, and the front body parts 11 and 21 and the back body part 12 made of front and back knitted fabrics A and B, respectively. , 22 are partly unconnected, in particular, the outer ends corresponding to the left and right sides of the clothing are connected and knitted, and the inner ends corresponding to the front and back center line portions of the clothing are not connected. A pattern having knitted crotch parts 13 and 23 and leg parts 15 and 25 continuously knitted in a cylindrical shape through the crotch parts 14 and 24 on the crotch parts 13 and 23 is formed. Furthermore, in the parts corresponding to the crotch parts 14 and 24 of the front body parts 11 and 21 and the rear body parts 12 and 22, respectively, extended knitted fabric parts 16a and 16b; 26a and 26b projecting outward are formed respectively. The pattern is such that the crotch height on the back body parts 12 and 22 side is higher than the crotch height of the front body parts 11 and 21.

  The left body part 10 and the right body part 20 of the pattern are knitted together with a cut-out spanning part (not shown) surrounding the periphery. The cylindrical leg portions 15 and 25 are formed into a cylindrical shape by connecting and knitting the front and back knitted fabrics A and B at both ends. The connecting knitting at the outer end is continuous to the connecting knitting at the outer end of the crotch portions 13 and 23, and the connecting knitting at the inner end is continued to the tops of the expanded knitted fabric portions 16a and 16b; 26a and 26b. Yes. The connecting knitting of the inner ends is continued to the vicinity of the base of the expanded knitted fabric portions 16a, 16b; 26a, 26b, and the end edges of the expanded knitted fabric portions 16a, 16b; 26a, 26b are set in a non-connected state. There is also a case.

  Usually, after knitting with the putter, the crotch part 13 in which the front and back knitted fabrics A and B are not connected to the left side body part 11 and the right side body part 21 which are cut and cut out from the crossing part. , 23 is sewn and joined at inner end portions corresponding to the front and back center line portions to constitute a lower body garment 1 as shown in FIG.

  In addition, the crossing portion is, for example, the structure described in the applicant's patent No. 4879068, that is, the well at the end portion of the knitted fabric portion that becomes the product, and the end portion of the other knitted fabric portion adjacent thereto. It is possible to use a tissue in which only the sinker loops are connected to each other through the underlap, and a tissue in which the number of sinker loops between the two wells is reduced.

  In addition, according to the present invention, the upper parts of the rear body parts 12 and 22 and the upper parts of the front body parts 11 and 21 and the side end parts on the front and back center line side of the crotch parts 13 and 23 according to the size. A plurality of index portions 17 and 27 for cutting are formed along the edge portions, respectively, and according to one index portion 17 and 27 selected from the plurality of index portions 17 and 27 based on the wearer's body shape and preference. The upper part of the lower body clothes 10, the upper part of the front body parts 12, 22, the upper part of the front body parts 11, 21, and the ends on the center line part side before and after the crotch parts 13, 23 can be cut at any line. It has become.

  The indicator portions 17 and 27 may, for example, move the knitting yarn in the line of the indicator portions 17 and 27 by one stitch when the other is knitting the pattern by swinging the stitcher loop. By knitting with 1 to 2 course intervals in the course direction, or knitting with the sinker loop direction reversed, the chain can be knitted integrally so as to appear on the back side. As a result, the formation of the indicator portions 17 and 27 can be efficiently performed at the same time as the knitting of the knitted fabric.

  The cutting does not have to be performed precisely in accordance with the indicator portions 17 and 27, and the cutting can be performed at an arbitrary line using the indicator portion as a guide. As a result, in comparison with the conventional lower body clothing that had to be selected from those with a fixed number of sizes, in the present invention, the shape and size of the wearer's body, especially the waistline (crotch) And stepless adjustment according to taste is possible, and an excellent wearing feeling can be obtained.

  In addition, the warp knitted fabric used in the present invention can be arbitrarily adjusted in shape and size of the crotch portions 13 and 23 by cutting, but since it has a warp knitting structure even if cut at any point, it is cut. Even if the portion is left as it is, fraying of the yarn at the cut portion is unlikely to occur, but it is more preferable that the cut portion is melt-bonded using a hot melt yarn or knitted with a knitting structure that is difficult to fray.

  In the case of the lower body garment 1 of the present invention, the front body parts 11 and 21 constituting the crotch parts 13 and 23 of the left body part 10 and the right body part 20 knitted on the front and back knitted fabrics A and B in the pattern, and The parts corresponding to the crotch parts 14 and 24 of the back body parts 12 and 22, that is, the parts corresponding to the front and back body parts 11 and 12; Expanded knitted fabric portions 16a, 16b; 26a, 26b are provided, and in the lower body garment 1 which is a product after sewing, the crotch portions 14, 24 are provided with a space to relax the feeling of cramping.

  The shape and size of the expanded knitted fabric portions 16a, 16b; 26a, 26b are not particularly limited, and may be set in consideration of wrinkle generation, work efficiency in sewing, etc. The triangular shape is preferable because the sewing operation is easy and it is difficult to cause wrinkles. The triangular shape of the expanded knitted fabric portion includes a generally triangular shape having a rounded top end or curved hypotenuse.

  When the shapes of the expanded knitted fabric portions 16a, 16b; 26a, 26b are triangular as shown in the figure, the expansion angle α1 of the distal ends of the expanded knitted fabric portions 16a, 16b; 26a, 26b is 45 to 140 degrees. The range of is preferable. When the spread angle α1 of the tip end portion is smaller than 45 degrees, the area of the tip end portion becomes small, and there is not enough room in the crotch portion, which causes a slight cramped feeling. On the contrary, when the spread angle α1 exceeds 140 degrees, the crotch portions 14 and 24 are slackened. Therefore, it is desirable to select appropriately within the above range according to the application and body shape.

  Moreover, in the said pattern, it is preferable to knit the rise height of the back body parts 12 and 22 higher than the rise height of the front body parts 11 and 21. FIG. In the present invention, the crotch height refers to the expansion knitted fabric portions 16a, 16b; 26a, 26b formed in the crotch portions 14, 24 of the crotch portions 13, 23 by the back body portions 12, 22 and the front body portions 11, 21. This refers to the length from the horizontal leg root line La passing through the top part to the upper ends of the crotch parts 13 and 23. Conventionally, the upper ends of the front and rear body parts 11 and 12; 21 and 22 of the crotch parts 13 and 23 are knitted parallel to the horizontal waist line Lb, and the back body side is the lower part of the hip when performing front and rear bending and stretching movements. There is a possibility that the lower part of the waist may be exposed by being pulled in the direction, but this possibility can be reduced by knitting as described above.

  More preferably, the pattern line at the upper end of the back body parts 12 and 22 in the crotch parts 13 and 23 is inclined upward by 3 to 20 degrees with respect to the horizontal waist line Lb when viewed from the outer end part of the binding knitting. Further, the pattern lines at the upper ends of the front body parts 11 and 21 in the crotch parts 13 and 23 are preferably 0 to 20 when viewed from the outer end part of the knitting knitting with respect to the horizontal waist line Lb. It is preferable to be knitted so as to incline downward.

  In addition, the angle α2 between the upper end pattern lines of the back body parts 12 and 22 and the upper end pattern lines of the front body parts 11 and 21 is preferably 3 to 40 degrees, and more preferably 10 to 30 degrees. . If the angle α2 is less than 3 degrees, it is difficult to make a difference between the rise height of the back body parts 12 and 22 and the rise height of the front body parts 11 and 21, and when standing or sitting repeatedly, or crouching posture When standing up from the back, the side of the back body parts 12 and 22 may be pulled downward and exposed, and the waist area may be exposed. Further, when the angle exceeds 40 degrees, there is a margin in the back body, but there is a possibility that wrinkles, distortion and sagging may occur around the hip.

  Further, in the pattern, the leg root line La that is horizontal through the tops of the extended knitted fabric portions 16a, 16b; 26a, 26b with respect to the length L2 of the waist line Lb that is horizontal at the upper portions of the crotch portions 13, 23. The length L1 may be appropriately set according to the size of the clothes and the wearer's body shape, but the length ratio (L2: L1) is preferably 1: 1.05 to 1.5. Furthermore, 1: 1.05 to 1.2 is preferable.

  By setting in this way, it becomes easy to adjust the length of the crotch parts 14 and 24 when sewing the front and rear parts of the crotch parts 14 and 24 after knitting. There is room for the lower part of the hip, and the feeling of cramping (compression) between the crotch parts 14 and 24 and the crotch is reduced when worn.

  If the ratio of the length L1 of the waist line Lb to the leg root line La is less than 1: 1.05, the expanded knitted fabric portions 16a, 16b before and after the crotch portions 14, 24; 26a , 26b almost disappears, and when worn, there is a feeling of cramping (compression) in the crotch parts 14 and 24 and the inseam, and a sense of incongruity is felt. Further, when the ratio of the length L2 of the waist line Lb and the length L1 of the leg root line La is larger than 1: 1.5, the expanded knitted fabric portions 16a, 16b; There is a risk of sagging in the crotch and sagging.

  The lower body garment 1 made of a cylindrical warp knitted fabric with the above pattern has, for example, a warp knitting machine such as a double raschel machine having two rows of needle beds shown in FIG. 1 and having two rows of jacquard guide bars. It is knitted mainly with a tube. At this time, the knitting machine gauge can be appropriately selected in accordance with the use and the body shape within the range of 14 to 32 gauge.

  The knitting yarn used in the present invention may be appropriately selected in accordance with the application and body shape within a range of 22 to 440 dtex. The material of the knitting yarn includes synthetic fibers such as nylon, polyester, polypropylene, and polyurethane, regenerated fibers such as rayon, natural fibers such as cotton and wool, etc., and the shape is long fiber yarn, short fiber yarn, those Composite yarns and the like can be mentioned, and the yarn is not particularly limited, and these can be combined appropriately according to the use such as mixed fiber or knit.
