Description

[Detailed Description of the Invention] This invention relates to an improvement of a belt member used for pants, particularly jeans.

Among all types of pants, jeans are loved by young people.
In particular, it is desired that it fit snugly around the waist.

For this reason, the belt part of jeans must have a gently curved shape that follows the waist line when the jeans are worn.

However, in order to make a belt member with such a shape, conventional belt fabric is cut into an arc shape and two pieces are stacked and sewn together. Therefore, sewing the jeans to the body is extremely troublesome.

There is also a known method in which a cloth tape that shrinks when absorbing moisture is sewn between two folded belt cloths and is sewn to one side to create a curved shape when humidified. Only the stitched portion of the tape contracts, causing wrinkles in the belt fabric, and when worn loosely, the stitched portion of the cloth tape digs into the abdomen, causing discomfort.

This invention provides a belt member for jeans that does not have the above-mentioned drawbacks.The invention is to provide a belt member for jeans that does not have the above-mentioned drawbacks.The purpose of this invention is to provide a belt member for jeans that does not have the above-mentioned drawbacks. and an interlining made of cloth using a warp that shrinks when humidified on the opposite side, and the side with the shrinkable warp is positioned toward the folded part of the belt cloth and glued in a halftone dot pattern. When humidified afterwards, the shrinkable warp yarns contract to form a gentle arc shape with the folded portion facing inside.

This will be explained in more detail below with reference to the accompanying drawings.

Fig. 1 shows an example of the belt member of the present invention, in which 1 is a belt cloth that is folded in two and is mainly made of cotton or a cotton fabric blended with a small amount of polyester fiber; It is a glued cloth interlining.

As shown in FIG. 2, the interlining 2 is made of, for example, polynister yarn, which has almost no shrinkage, for the warp threads 2a on one side in the longitudinal direction, and for example, highly shrinkable rayon, for the warp threads 2b, on the opposite side. It is made of a woven fabric using yarn, and its warp 2b side is positioned toward the folded portion 1b of the belt cloth 1, and is bonded to the back surface of the belt cloth 1a with an adhesive in a halftone dot pattern.

The dot-like adhesion referred to here is shown in Figure 3-A. It refers to a net-like uniform dot adhesion as shown in the mouth.

In the proposed belt member having such a structure, the selvage on the side of the folded portion 1b is sewn, the ends of the body of the jeans are sewn to the selvages on the opposite side, and then the selvage is moisturized by boiling or soaping. As a result, the folded portion 1b side of the pelt cloth 1 contracts, resulting in a belt portion having a gently curved arc shape as shown in FIG.

The proportion occupied by the contractile warp yarns 2b is limited to the width of the interlining 2, and the degree of contraction to form an arc shape in the belt member is adjusted by the number of constitutive warp yarns 2b (warp density). do it.

Incidentally, the warp threads 2a are polyester No. 10 single threads (shrinkage rate 0.
1%) at a density of 25 yarns/inch, the warp yarn 2b is made of No. 10 single rayon yarn (shrinkage rate 8.25%) at a density of 50 yarns/inch, and the weft is made of 25 polyester No. 10 double yarns.Width: 40m A belt member was obtained by gluing the interlining material (2a: 2b = 25 + 1011: 15M) between two folded cotton belt cloths with a width of 50 r + on in the above-mentioned manner, and the belt members were machined on both sides. When the sample was immersed in hot water at 600C for 20 minutes to dehydrate and then dried, a gently curved belt portion with a large radius of curvature (r=970rIrIn) was formed.

As described above, according to the belt member of the present invention, the fabric used for the belt cloth can be easily cut without generating cutting waste, and since both side edges are straight before sewing, it is easy to sew the fabric to the body of jeans. Furthermore, after being moisturized and dried, the finished product has smooth curves and a clean appearance without wrinkles.

There is also a secondary advantage that processing costs are low.

Claims (1)

[Claim for Utility Model Registration] On one back side of the folded belt cloth 1, along the longitudinal direction, warp threads with almost no shrinkage are placed on one side, and warp threads that are shrinkable due to humidification are placed on the other side. The used cloth interlining 2 is bonded in a halftone dot shape with the side with the shrinkable warp facing the folded part 1b of the belt cloth, and is moistened after sewing so that the folded part is turned inside. A belt member for jeans that forms a high-grade arc shape. (
