Description

  The present invention relates to a sewn structure of a waist portion of underwear, in which tightening marks are less likely to remain on the waist portion of the body.

  Conventionally, briefs, trunks, panties, girdles, spats, tights, pajamas, sports shorts, swimwear, and the like are known as underwear that directly touch the skin and fasten the waist. As shown in the perspective view of the main part viewed from the back side of FIG. 5, this type of underwear 1 is usually composed of a knitted fabric or a woven fabric having elasticity, and its waist portion. A rubber band (hereinafter also referred to as a waist tape) 4 is attached to 3 in order to prevent sliding down.

  Then, the end 5 of the fabric constituting the underwear main body portion 2 is folded back so as to be on the back side of the underwear 1, and a rubber band 4 is applied thereon, for example, zigzag in a vertical direction called a three stitch 6. Sewing is done and finished. Such fabric end cleaning has been performed because the fabric end 5 is easily frayed, cannot withstand use, and fibers that have frayed from the end jump out and become unsightly.

  However, in the case of the end cleaning method as described above, the waist portion with the rubber band 4 is provided due to the fact that it is folded back, the rubber tape 4 is attached, and the seam is formed by the sewing thread of the three stitch 6. The bank-like convex part 8 with a level | step difference will be made. In addition, the bank-like convex portion 8 has a higher expansion / contraction force than other portions because it is necessary to prevent the clothing from sliding down, and is firmly crimped to the body. Therefore, the bank-like convex part 8 bites into the meat of the waist part of the body, and there is a problem that a trace of the bank-like convex part 8 so-called rubber band 4 remains on the body and there is a feeling of pressure. It was. In addition, since the bank-like convex portion 8 is further tightened by wearing outerwear such as a skirt or slacks, the phenomenon that the trace of the rubber band 4 remains on the skin surface of the body and the feeling of pressure are further increased. Not only does the feeling of wear decrease, but the thickness of the waist portion 3 increases when the clothing is layered, so that there is a problem that it is difficult to produce a clean slim beautiful waistline.

  An object of the present invention is to eliminate the need for folding the edge of the fabric forming the bank-like convex portion, and thus to solve the problems as described above.

  That is, the present invention eliminates the need for folding around the edge of the fabric, making the bank-like convex part difficult or smooth, significantly reducing or preventing biting into the waist of the body, Underwear that is smooth and has a smooth texture that fits the body, making it difficult to remain on the body skin surface, reducing the feeling of pressure, improving the feeling of wear, and creating a slim and beautiful waistline. It aims at providing the sewing structure of the waist part.

  In order to achieve the above object, the sewing structure of the waist portion of the underwear according to the present invention has a pair of front and back side stitches on the sewing side edge to the end of the fabric in the main part of the waist tape (rubber band). The waist part is provided in a state that can be freely opened and closed, and is sewn between the front side and back side seam allowances with the end of the body material of the underwear body sandwiched without being folded back, and the waist tape Is a main part composed of a woven portion that expands and contracts in the direction of the warp and does not expand and contract in the direction of the weft, and a direction of the warp in which one end of the weft of the main part is extended in the width direction and the extension is woven as a weft. Is composed of a pair of front and back side seam allowances composed of a weaving portion that expands and contracts in the direction of the weft.

  Further, the main portion is made of stone weave in which two thick elastic yarns are used as warps and two non-elastic yarns are used as weft yarns. The extension portion is used as a single weft yarn in a state where it is distributed for each front side and back side seam allowance, and one of the fine elastic yarns is made into a plain weave used as a warp.

  According to the sewing structure of the waist portion of the underwear according to the present invention, when the waist tape is sewn to the end of the fabric, it is possible to omit the step of folding the end of the fabric. Not only has the advantages of simplifying the process, simplifying the manufacturing equipment, shortening the production process, improving productivity, etc., but the waist tape thus puts the end of the fabric against the fabric. When sewn in a state where there is no folded portion, it is possible to reliably reduce the thickness by at least the amount of the state where there is no folded edge, so that the protruding height of the bank-like convex portion can be significantly reduced. .

  Further, the front and back side seam allowance portions are constituted by plain weaves of one weft and one warp made of fine elastic yarn distributed from the main part for the front side and back side seams. As a result, it is possible to efficiently mass-produce a waist tape having a remarkably thin plain weave on the edge of the main part of the stone texture weave in a state in which the seam allowances are continuously continuous.

  In short, according to the sewn structure of the waist part of the underwear according to the present invention, it is possible to solve the above-mentioned problems, and no tightening marks remain on the waist part of the body or it is difficult to remain. It is possible to provide an underwear with a good wearing feeling.

  In addition, it is difficult for consumers to bite into the waist part of the body, and in particular, it is difficult to leave traces of rubber tape on the body, the feeling of pressure is reduced, the feeling of wearing is improved, and It is possible to easily and inexpensively provide a non-defective product that fits a body that is smooth and has a smooth texture, so that a clean and beautiful waistline can be produced, and sufficient satisfaction can be provided.

  Hereinafter, the present invention will be described in detail based on embodiments with reference to the drawings. This embodiment is described based on the most orthodox male brief as an example of underwear. However, the type of underwear is not limited to this, and the trunks and panties described above are not limited thereto. In addition to girdle, tights, spats, pajamas, sports shorts, swimwear, etc. may be used.

Fig. 4 is an enlarged perspective view of the main part, and Fig. 4 is an explanatory view of the main part, schematically showing how the waist tape is woven.

  In the figure, 11 is a stretchable waist tape (rubber band) made of woven fabric, and 12 is a brief body made of knitted fabric having stretchability.

  The waist tape 11 extends and contracts in the direction of the warp yarns 13a and 13b, and has a main portion 15 composed of a woven portion that does not expand and contract in the direction of the weft yarns 14a and 14b, and one end of the weft yarns 14a and 14b of the main portion 15 in the width direction. A pair of front and back side stitches consisting of a woven portion which is woven in the direction of the warp yarns 17a and 17b and which does not expand and contract in the direction of the weft yarn (extension portions 16a and 16b). It is comprised by the margin parts 18 and 19, and between these front side seam allowance parts 18 and the back side seam allowance parts 19, the end 12a of the said brief main body fabric (body body fabric) is pinched | interposed without folding back, and is a stretchable stitch It is sewn by the sewing 20.

  As shown in the explanatory view of FIG. 4, the main body 15 is a woven portion made of a texture using two thick warps 13 a and 13 b and two wefts 14 a and 14 b. The warp yarns 13a and 13b of the stone weave are stretch nylon and lycra (product name) yarns that are double covered with lycra soft (product name) yarns as stretch yarns. As the weft yarns 14a and 14b, filament nylon yarns are employed as non-stretchable yarns.

  Further, as shown in the explanatory diagram, the front and back side seam allowance portions 18 and 19 are plain woven using a single fine warp yarn 17a, 17b and a single weft yarn (extension portions 16a, 16b). This is a woven part. The weft yarn of the plain weave portion is provided by extending one end of the weft yarns 14a and 14b in the above-mentioned stone weave portion in the width direction and distributing the extension portions 16a and 16b to one for each of the front and back side seams. In addition, the warp yarns 17a and 17b, like the warp yarns 13a and 13b of the main portion 15, are stretch nylon yarns and lycra (trade name) yarns that are double covered with lycra soft (trade name) yarns to expand and contract. It is used as a sex thread.

  Therefore, in the sewing structure of the waist portion of the underwear, the thickness of the back side seam allowance portion 19 that is plain weave using one fine warp 17a, 17b is two thick warps 13a, 13b. As a result, it is possible to reduce the thickness of the main portion 15 made of a stone texture to about half or less (see FIGS. 2 and 3). As a result, the end 12a of the brief body fabric (body fabric) is folded back. The protruding height of the bank-like convex portion can be remarkably lowered in combination with being sewn without being cut.

  In addition, when the waist tape in the present invention is provided as a product that is not attached to the underwear body, that is, a product that can be used by the consumer as appropriate, it can be arbitrarily attached to the end of the clothing or other fabric. These can also be included in the category of the present invention.
