Description

[0001]
TECHNICAL FIELD OF THE INVENTION
The present invention relates to trunks and shorts-type bottom underwear, particularly sanitary underwear.
[0002]
[Prior art]
Conventionally, as shown in FIGS. 7 and 8, there has been known a sanitary bottom underwear composed of a trunk 21 covering a waist and a crotch portion 23 in which a waterproof cloth 22 is sewn on an inner surface corresponding to a crotch. ing. The waterproof cloth 22 is so-called plane cut into a substantially elliptical shape.
[0003]
The bottom underwear provided with the waterproof cloth has a drawback that the crotch portion does not easily fit into the curved crotch surface when worn, and excrement is easily leaked because the waterproof cloth has poor elasticity and is flat.
[0004]
[Problems to be solved by the invention]
SUMMARY OF THE INVENTION It is an object of the present invention to provide a bottom underwear in which a crotch portion fits comfortably and smoothly on a crotch body surface so that excrement is less likely to leak out.
[0005]
[Means for Solving the Problems]
In order to solve the above-mentioned problem, the present invention is directed to a bottom underwear including a waist body covering a waist and a crotch part provided with a waterproof cloth corresponding to a crotch body, wherein the waterproof cloth has a pair of substantially bows. They were sewn using a trimmed cloth with the opposing edges of both recesses facing each other.
[0006]
Further, it is preferable that a waterproof tape is adhered to the waterproof cloth on a suture line. Further, a laminate of a low-temperature softening film and an elastic film is preferably used as the waterproof tape.
[0007]
[Action]
According to the bottom underwear of the present invention, the waterproof cloth on the inner surface of the crotch portion is formed of draped cloth, and has a curved shape as if the central portion swells. Fits comfortably and smoothly.
[0008]
Further, the waterproof tape is closely adhered to the suture line, so that the gap of the sewing allowance, the through hole of the sewing machine needle and the like are completely sealed, so that excrement does not leak.
[0009]
Further, the waterproofing tape is easy and reliable because the low-temperature softening film is applied to the adhesive surface, so that the bonding operation is easy and reliable. large.
[0010]
BEST MODE FOR CARRYING OUT THE INVENTION
An embodiment of the present invention will be described below with reference to FIGS. As shown in FIG. 1, FIG. 2 and FIG. 3, this bottom underwear is a covered yarn in which a core yarn is made of an elastic yarn of polyurethane or the like which imparts required elasticity to the fabric, and this is covered with a cotton / polyester blended yarn or the like. A waist 1 covering a waist sewn from a warp knitted fabric such as a tricot having a dense stitch and a certain degree of elasticity, and a waterproof crotch 2 corresponding to a crotch , A vertically long waterproof cloth 4 formed by draping is sewn on the inner surface of the crotch portion 2 at its peripheral seam 5. It was done.
[0011]
A high elastic waist band 6 is attached to the upper edge of the torso 1 on the bottom underwear, and the edges of the legs 3, 3 are provided with edges 7 and 7 formed by folding back a cloth.
[0012]
Further, on the upper surface of the waterproof cloth 4, the front edge suture line 9 and the suture lines 10, 10 of the rear right and left corners are formed such that a napkin support cloth 8 made of a power net provides a gap between the waterproof cloth 4 and the napkin support cloth 8. Mounted by three-point support.
[0013]
As shown in FIG. 4, FIG. 5, and FIG. 6, the waterproof cloth 4 is a pair of left and right substantially draped woven fabrics obtained by waterproofing a warp knitted fabric such as a tricot with a fine stitch and reduced elasticity. Using the bow-shaped sewn cloths 11, 11, the concave and opposing edges 12, 12 of both sides are butted together and sewn at a central suture line 13.
[0014]
The waterproof cloth 4 has a two-layer waterproof film 16 composed of a low-temperature softening film 14 such as polyurethane, which is easy to melt, and an abrasion-resistant, heat-resistant, elastic film 15 such as vinyl chloride. Is fused at a low temperature of about 160 ° C., for example.
[0015]
The waterproof cloth 4 is formed by sewing left and right bow-shaped cutting cloths 11, 11 which are cut three-dimensionally in accordance with the body surface of the crotch body, and has a large number of folds 17, 17 on the peripheral edge. When sewn with the peripheral suture line 5, it takes on a required curved shape such that the vicinity of the central suture line 13 swells, and when worn, it fits comfortably and smoothly on the inseam of the indented part, such as during heavy exercise In this case, it is sanitary without excrement leakage.
[0016]
The crotch portion may be used for a relatively small regular or sports one corresponding only to the inseam, or for a large night where the rear part reaches the waist band 6 at the upper edge of the back body. Further, the napkin support cloth 8 can be omitted.
[0017]
The cutting cloth 11 forming the waterproof cloth 4 may be appropriately selected in shape such as width and length, dimensions of the radius of curvature of the concave curved opposing edge and the outer curved outer edge, and the like according to the application. It may be formed by automatic stencil drafting or automatic cutting by a computer in consideration of human motion and the like, in addition to draping according to a stand or the like.
[0018]
In addition, the waterproof cloth 4 has both the seam allowances overlapped on one side at the central suture line 13 and one side thereof is turned over, and the waterproof tape 16 is adhered thereon, so that the gap of the seam allowance and the sewing machine needle through hole are completely removed. It becomes closed (see FIG. 6).
[0019]
As described above, in addition to polyurethane as the low-temperature softening film, other waterproofing resin films such as polyethylene may be used as the waterproofing tape 16, and vinyl chloride as the high elasticity film, and other heat-resistant and high-resistant materials such as polyester may be used. An elastic resin film can be used.
[0020]
As described above, the bottom underwear according to the present invention can be applied to various types such as a trunks type having short legs and a shorts type having no legs. It is also possible to improve the tightness of the waist by providing a hip gather in the vertical direction, and to make the knitted fabric a weft knitting structure in addition to a warp knitting structure.
[0021]
As the fiber material, in addition to three types of mixed yarns of a polyurethane core yarn and a cotton / polyester mixed yarn covering the same, polyurethane / cotton / acrylic mixed yarn, polyurethane / cotton mixed yarn, polyurethane / polyester mixed yarn, cotton 100 % Yarn, 100% polyester yarn or the like can be appropriately selected according to the application.
[0022]
Further, the bottom underwear may be a solid color in a color such as blue, pink, black, or gray, or may be printed on a flower pattern, a camouflage pattern, a hail pattern, etc., and may be denim-like jeans. A knitted fabric or a brushed fabric can be used, and a lace fabric can be inserted into a part of the body or a lace band can be used as a border.
[0023]
【The invention's effect】
According to the present invention, as described above, in the most important crotch portion as the sanitary bottom underwear, the waterproof cloth is cut and sewn by three-dimensional cutting, and has a curved shape corresponding to the outer surface of the human body, When worn, it fits snugly into the three-dimensional inseam of the inseam, and the leakage tape is almost completely blocked by the waterproof tape with tightly sewn lines.It is excreted not only for daily use, but also for night use, sports use, etc. It is extremely sanitary with no leaks.
[0024]
In addition, a cold-softening film is used for the adhesive surface of the waterproof tape, which is easily and reliably fused to the waterproof cloth, does not damage the waterproof cloth, and has a large flexibility because one side is an elastic film. There are effects such as no discomfort.
