Abstract

<P>PROBLEM TO BE SOLVED: To provide good appearance underwear whose edge following parts are thinly finished so as to be prevented from getting wavy. <P>SOLUTION: The underwear has the following structure: a tape 3 thinner than a body fabric and having the same level of stretchability as that of the body fabric is superposed on the reverse side of the edge part of an underwear body 2 formed of stretchable body fabric along its edge border; and the underwear body 2 and the tape 3 superposed on each other are sewn with lock stitches in zigzags along their edge borders. <P>COPYRIGHT: (C)2006,JPO&NCIPI

Description

  The present invention relates to an undergarment made of stretchable body cloth.

Normally, the end of underwear, such as shirt hems and cuffs, is zigzag-locked along the edges to prevent fraying, and then the end is folded back to the back to the appropriate width and straight stitched. Often sewn with.
However, when the edge treatment is performed in this way, the end of the underwear becomes thick, and the feeling of wearing becomes worse. When a thin outer garment is worn on the surface, irregularities appear on the surface and the appearance is There is a disadvantage of being bad.
In addition, it is conceivable that the edge of the underwear is simply zigzag-locked and processed, but if the body fabric of the underwear is an elastic fabric, it is possible to Since the restorability of the body fabric is hindered and remains stretched, the end of the underwear wavy, the appearance of the underwear itself deteriorates, and the fabric of the end of the underwear overlaps and becomes wrinkles when worn, The appearance of the outer garment is bad.

  The problem to be solved by the present invention is to provide an undergarment in which the edge processing portion is finished thin and the occurrence of undulation can be suppressed.

The undergarment of the present invention is made of a stretchable body cloth, and a tape that is thinner than the body cloth and has approximately the same stretchability as the body cloth is stacked on the back of the end of the underwear body along the edge. The polymerized underwear body and the tape are zigzag-locked along the edge.
The tape may be obtained by cutting an elastic net.

According to the first aspect of the present invention, since the tape thinner than this is overlapped on the end portion of the body fabric, and the lock fabric is only once sewn, the end portion is obtained by folding back the body fabric subjected to the lock stitching and finishing it by straight stitching. Since the thickness of the fabric is thin and the restoring force of the body cloth and the tape is combined and resists the tensile force of the lock stitching thread, it is possible to prevent the ends from wavy.
In addition, the fabric and the tape have the same degree of elasticity, so the elasticity of the tape is too strong and the edges of the underwear body are wrinkled, or the elasticity of the tape is too weak to inhibit the extension of the edge. However, it does not become difficult to attach and detach.
According to the invention of claim 2, since the tape is made of a material that does not fray, even if the tape protrudes from the lock stitched portion, there is no fear that the portion will fray when used for a long time or repeated washing. .

Hereinafter, an embodiment in which the underwear is an undershirt without sleeves will be described in detail with reference to the drawings. FIG. 1 is a back view of the undershirt 1, and FIG. 2 is a cross-sectional view of the hem portion of the undershirt 1.
The undershirt 1 is made of a stretchable fabric including polyurethane, and as shown in FIGS. 1 and 2, a stretchable tape 3 is provided along the edge of the back surface of the bottom of the shirt body 2. In addition, the shirt body 2 and the tape 3 that have been polymerized are finished in a zigzag lock fashion along the edges.

The tape 3 is obtained by cutting a stretchable net that is thinner than the body cloth of the undershirt 1 and has approximately the same stretchability as the body cloth into a width of 6 mm to 10 mm. The color of the tape 3 is preferably the same color as the body cloth.
If the elasticity of the tape 3 is too strong compared to the fabric, the hem of the undershirt 1 will be pulled by the tape 3 and wrinkles will occur. Conversely, if the elasticity of the tape 3 is too weak, Growth is inhibited.

For lock stitching, a stretchable sewing thread 5 is used. The width of the lock stitching portion 4 (zigzag swing width) varies depending on the thickness and stretchability of the undershirt 1, but is 5 mm to 7 mm.
If the width of the lock stitch portion 4 is narrower than 5 mm, the hem end rises to a substantially circular cross section, and the hem end may be rolled up and feel bad, and the hem end may be rolled up (curling).
On the other hand, if the width of the lock stitch portion 4 is wider than 7 mm, the end portion of the shirt body 2 and the tape 3 are attracted by the force of the reciprocating sewing thread 5, and there is a concern that the width shrinks to cause a recumbent.

Since the width of the tape 3 is slightly wider than the width of the lock stitching portion 4, the end portion of the tape 3 protrudes from the lock stitching portion 4, but the tape 3 is made of an elastic net that does not fray. Even if it repeats, the edge part of the tape 3 is not frayed.
Not only the hem of the undershirt 1 but also the cuffs of the undershirt with sleeves and the end of the underwear other than the undershirt can be processed in the same manner.
In addition, if it is thinner than the body cloth and has the same degree of stretchability and is slightly wider than the width of the lock stitched portion, it will be frayed to the edge instead of the tape 3 with the stretchable net cut. A long tape that has been processed can also be used.
