Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a slacks and a method of manufacturing the slacks, and more particularly, to a slacks which is provided with excellent durability to the slacks line and can be kept in a good state for a long time, and an advantageous manufacturing thereof. It is about the method.

[0002]

BACKGROUND ART Generally, a slacks has a slacks line composed of folds set by steaming or the like on at least a front side and a rear side of a leg portion of the slacks.
And, this slacks line plays a role of preventing the occurrence of wrinkles and deformation by making the slacks always foldable in the same state, and at the same time gives a straight silhouette when worn to improve the appearance. Is also responsible.

By the way, in such a slacks, a pulling force in various directions is applied when the slacks are worn, depending on the behavior of the wearer. The pulling force is also exerted in the direction (left-right direction) in which the fold line forming the slacks line is widened.

Therefore, as described above, in the slacks in which the slacks line is formed simply as a fold by steaming or the like, it is inevitable that the slacks line is gradually thinned every time it is worn.
This has caused problems such as wrinkles, deformation, and deterioration of appearance.

Therefore, various efforts have been made so far to obtain a slacks having a slacks line excellent in durability. As one of them, a slacks in which a slacks line is set according to the procedure shown in FIG. 7 is known. That is, in the slacks 32, first, as shown in FIG. 7A, the adhesive tape 34 is placed on the back side of the slacks line forming portion 30 of the leg portion 12, and then placed. As shown in (b) of the figure, at the slacks line forming portion 30, the adhesive tape 34 is bent so as to be inward, and as shown in (c), steaming or the like is performed from the front side. The fold line is formed and the slacks line 14 is set, and at the same time, the adhesive tape 34 is adhered to the back sides of both side portions 16 of the slacks line 14.

Thus, in such a slacks,
Due to the bending, the overlapping position of the adhesive tape 34 on the back side of the slacks line forming portion 30 is changed from the position where the adhesive tape 34 is initially arranged on the back side of the slacks line forming portion 30 to the back side direction (in the figure). , The right direction), the adhesive tape 34 is
The slacks line 14 is bonded so as to straddle both side portions 16 of the slacks line 14, whereby the pulling force generated according to the behavior of the wearer causes the fold line forming the slacks line 14 to expand. (In the figure,
When the slacks line 14 is acted in the vertical direction), both side portions 16 of the slacks line 14 are pulled by the adhesive tape 34 and do not spread in the direction away from each other.

However, since the slacks 32 have the above-mentioned structure, the adhesive tape 34 is pulled by the pulling force applied in the direction of expanding the folds forming the slacks line 14.
It was unavoidable that the tape was stretched by being pulled in the widthwise direction, and in some cases, the adhesive tape 34 itself could cause both side portions 1 of the slacks line 14 to move.
It even peeled off from the back side of 6,16.

Therefore, in the conventional slacks 32, the slacks line 14 by the pulling force as described above is used.
It was difficult to sufficiently prevent the expansion of both side parts 16, 16 of the slack line 14.
It was impossible at all to say that it was sufficiently satisfactory for practical use in order to keep good performance for a long period of time.

[0009]

[0020]

DESCRIPTION OF THE PREFERRED EMBODIMENTS In order to clarify the present invention more specifically, representative embodiments of the present invention will be described in detail with reference to the drawings.

First, FIG. 1 shows a schematic view of a wool fiber slacks to which the present invention is applied. As is clear from this figure, in the slacks 10,
Slack lines 14, 14 are formed at the central portions of the legs 12, 12 into which both feet are inserted so as to extend continuously in the vertical direction. Although not explicitly shown in this figure, the leg portion 1 of the slacks 10
The slacks lines 14 and 14 are also on the back side of 2 and 12.
However, similarly to the front side, they are continuously formed in the vertical direction.

Then, as is apparent from FIG. 2 which is an enlarged cross-sectional view of the peripheral portion of the slacks line 14 of the slacks 10, the slacks line 14 is
Are formed on the front side of the slacks 10 by a fold line having an inverted V-shaped cross section so as to protrude by a predetermined dimension.

On the back side (lower side in the figure) of both side portions 16, 16 of the slacks line 14, a first adhesive tape 18 and a second adhesive tape 20 are overlapped with each other, It is distributed. As shown in FIG. 3, each of the first and second adhesive tapes 18 and 20 is made of a belt-shaped thin cloth 22 having a predetermined width, which is composed of a heat-shrinkable plain weave structure made of polyester fiber. A heat-sensitive adhesive 24 is scattered and adhered to one surface, whereby a heat-sensitive single-sided adhesive tape having the one surface as an adhesive surface 26 is formed. There is. Although not shown, the first and second adhesive tapes 18 and 20 have substantially the same length as the slacks line 14.

And such a first adhesive tape 18
However, with respect to the back side of both side portions 16, 16 of the slacks line 14, in a state of straddling the both side portions 16, 16,
In addition, the second adhesive tape 20 is the first adhesive tape 18
They are heat-sensitively bonded so that they overlap each other (see FIG. 2).

By the way, the slacks 10 having such a structure is manufactured as follows.

That is, first, in the same manner as in the prior art, a predetermined cloth is cut and sewn, and the slacks 1 before finishing is processed.
Produce 0. Then, as shown in FIG.
In such slacks 10, at least each leg 12
The first and second adhesive tapes 18 and 20 are arranged on the back sides of the front and rear slack line forming portions 30, respectively.

More specifically, the first adhesive tape 18 is
The adhesive surface 26 is superposed on the back side of the slacks line forming portion 30 and arranged along the slacks line forming portion 30, and the second adhesive tape 20 is attached to the adhesive surface 26 at the first side. The adhesive tape 18 is superposed on the non-adhesive surface 28 and arranged along the non-adhesive surface 28. Here, in order to prevent the first and second adhesive tapes 18 and 20 from peeling off, the back side of the slack line forming portion 30 and the non-adhesive surface 28 of the first adhesive tape 18 are respectively removed. The first and second adhesive tapes 1 are, of course, arranged to be temporarily bonded and arranged.
There is no problem even if 8 and 20 are sequentially stacked and arranged.

Next, as shown in FIG. 4 (b), the leg portion 12 is vertically moved at the slack line forming portion 30 so that the first and second adhesive tapes 18 and 20 are located inside. Fold along. Then, as shown in FIG. 4C, the leg 12 is heated and pressed from the front side using, for example, a steam iron to form a fold line in the slacks line forming portion 30 along the vertical direction. At the same time, the first adhesive tape 18 is heat-sensitively adhered to the back side of the slack line forming portion 30, and the second adhesive tape 20 is heat-sensitively adhered to the non-adhesive surface of the first adhesive tape 18. As a result, in the state of FIG. 4 (c) to FIG.
The second adhesive tape 20 and the first adhesive tape 18 are adhesively fixed to the cloth and the first adhesive tape 18, respectively. That is, the first and second adhesive tapes 18,
The adhesive 24 applied to the adhesive surfaces 26, 26 of 20 spreads out on each adhesive surface 26 and penetrates into the cloth 22 which is a tape base material. At least two adhesive tapes on the back side 1
A relatively long fixing area having a length corresponding to the overlapping thickness of 8 and 20 is formed, and two adhesive tapes 1 are formed.
The heat shrinkage of 8 and 20 causes tensile stress in the adhesive tapes 18 and 20.
This is a force for pulling 6, 16 in the direction of the slacks line 14.

Thus, the slacks 10 in which the slacks lines 14 are set are produced at least on the front and rear sides of the legs 12 and 12 along the vertical direction thereof. In particular, in the slacks 10, the first adhesive tape 18 is provided on both sides of the slacks line 14 on the back side of the side portions 16 and 16 at the overlapping position as described above. And the second adhesive tape 20 overlaps the first adhesive tape 18 at the overlapping position as described above on the non-adhesive surface of the first adhesive tape 18, respectively. , They can be glued together.

Therefore, in such a slacks 10, when a pulling force is applied in a direction in which the fold forming the slacks line 14 is widened (left and right direction in FIG. 2) depending on the wearer's behavior, Slacks line 1
The two side parts 16 and 16 of FIG. 4 can be pulled by the first adhesive tape 18 so as to prevent the expansion of the both side parts 16 and 16, and together with that, The adhesive tape 18 of FIG.
The expansion of the first adhesive tape 18 in the width direction due to the pulling force associated with the expansion of the adhesive tapes 18 and 20 is prevented. It is further enhanced by the presence of tensile stress, which is due to the heat shrinkage due to the thermal bonding of.

Therefore, in the slacks 10 according to the present embodiment, in addition to the effect of increasing the fixed area by superimposing the first and second adhesive tapes 18 and 20, the slacks line 14 formed by the first adhesive tape 18 is provided. Both side parts 1
The expansion preventing effect of Nos. 6, 16 and the expansion preventing effect of the first adhesive tape 18 by the second adhesive tape 20 are combined,
The widening of the fold forming the slacks line 14 can be very effectively prevented, and the slacks line 14 can be kept in a good condition for a longer period of time.

Further, in such slacks 10,
Since the first and second adhesive tapes 18 and 20 are made of the strip-shaped cloth 22 having a predetermined width, both adhesive tapes 18 and 20 can be freely bendable,
A good slacks line 14 can be easily formed.

Further, in the slacks 10, the first and second adhesive tapes 18 and 20 are
Since the adhesive 24 is scattered on one surface of the cloth 22, the amount of the adhesive 24 used can be easily adjusted, and the slacks line due to excessive use of the adhesive 24 can be adjusted. Bleeding of both side portions 16, 16 of 14 can be advantageously prevented, so that both side portions 16, 16,
It is possible to effectively prevent problems such as deterioration of the outer appearance of the area around 16 and occurrence of discomfort for the wearer.

Furthermore, in the slacks 10, since the adhesive 24 has heat sensitivity, the slacks line 14 is set by only hot pressing with a steam iron or the like. And the adhesion processing of the first and second adhesive tapes 18 and 20 to predetermined portions can be performed at the same time, whereby the manufacturing process can be advantageously simplified and the improvement of the manufacturability is effective. In addition to the above, the expansion action of both side parts 16 and 16 of the slacks line 14 can be effectively prevented by the pulling action caused by the thermal contraction of the adhesive tapes 18 and 20. Of.

Further, in such slacks 10,
In the manufacturing process, the set of the slacks line 14 and the adhesion of the first and second adhesive tapes 18 and 20 are
Since it can be performed in one step, the slacks line 14 having excellent durability can be easily set.

Further, in the slacks 10, the backside of the slacks line forming portion 30 and the first adhesive tape are prevented so that the first and second adhesive tapes 18 and 20 do not come off during the manufacturing process. The first and second adhesive tapes 18 and 20 are moved from their positions without any special operation, because they are temporarily bonded and arranged on the non-adhesive surfaces 28 of 18 respectively. However, the falling off can be effectively prevented, and the workability in the subsequent bending work and pressing work can be effectively improved. The temporary adhesion between the first adhesive tape 18 and the second adhesive tape 20 is
It is realized by spot (partial) bonding, not by bonding the two adhesive tapes over the entire surface. Specifically, both adhesive tapes are bonded at stripes or line portions at predetermined intervals, or at predetermined intervals. It is carried out by adhering them at the dotted portions.

Although the representative embodiments of the present invention have been described in detail above, they are literal examples, and the present invention is not construed as being limited to those examples. Needless to say.

For example, in the above-mentioned embodiment, the second adhesive tape 20 is adhered to the first adhesive tape 18 so as to overlap each other in the form of a single tape. A plurality of adhesive tapes may be used as the adhesive tape 20, and the adhesive tapes 20 may be adhered to the first adhesive tape 18 in a state of overlapping each other. Thereby, the plurality of second adhesive tapes 20
Among them, the one located on the side of the first adhesive tape 18 is advantageously prevented from extending in the width direction by the pulling force due to the expansion of both side portions of the slacks line by the one located on the opposite side. As a result, it is possible to more effectively prevent the fold line forming the slacks line from being widened by the pulling force applied during wearing.

Further, the polymerized adhesive form or the polymerized adhesive structure of the first and second adhesive tapes 18 and 20 is not limited to the one in the above-described embodiment, and the first adhesive tape is not limited thereto. 18 is adhered to the back sides of both side portions 16, 16 of the slacks line 14 so as to straddle it, so that expansion of the both side portions 16, 16 can be prevented. Further, the second adhesive tape 20 may be adhered to the first adhesive tape 18 so as to overlap with the first adhesive tape 18, and the extension in the width direction due to the pulling force due to the expansion of the both side portions 16 and 16 may be prevented. If so, any structure can be adopted. Specifically, the first adhesive tape 1
8 and the second adhesive tape 20 may be adhered over the entire surface, or even a structure in which they are adhered at necessary portions does not cause any problem, and the first adhesive tape 18 and the second adhesive tape 20 may be attached together. , Not only in the case of completely polymerizing the same width as shown in FIGS. 2 and 4,
As shown in FIG. 5, it is also possible to overlap and adhere only in a predetermined width, and further, as shown in FIG.
The first adhesive tape 18 is made wider than the second adhesive tape 20 to form the overlapping portion of the first and second adhesive tapes 18, 20 in the vicinity of the slacks line forming portion 30, while both end portions in the tape width direction are formed. Then, it is also possible to configure so that only the predetermined width portion of the first adhesive tape 18 exists. In particular, as shown in FIGS. 5 and 6, if both ends in the tape width direction are constituted by only one adhesive tape (18, 20) portion in a predetermined width,
It is desirable that the lines of the end portions of the first and second adhesive tapes 18 and 20 that are superposed on each other do not easily appear on the front sides of the slacks line both side portions 16 and 16 and that a good appearance is exhibited.

Further, in the above embodiment, the first and second adhesive tapes 18 and 20 are heat-sensitive adhesives in which the heat-sensitive adhesive 24 is scattered and adhered to one surface of the cloth 22. Although constructed as a single-sided adhesive tape, the structure of the first and second adhesive tapes 18, 20 is never
It is not limited to this. That is, for example, a material other than cloth may be used as the base material for providing the first and second adhesive tapes 18 and 20, and an adhesive that is not heat-sensitive may be used. Further, it is of course possible that the adhesive is adhered in the form of a layer, or that a double-sided adhesive tape having both surfaces as adhesive surfaces is formed by applying a predetermined adhesive to both surfaces. In particular, when the double-sided adhesive tape is used as the first adhesive tape 18, the second adhesive tape 20 may be a tape made of only a base material such as cloth (without an adhesive). . Furthermore, even if the first adhesive tape 18 and the second adhesive tape 20 have different structures, there is no problem.

In addition, in the above-mentioned examples, specific examples of the present invention applied to wool fiber slacks are shown, but the present invention uses yarns made of other fibers such as synthetic fibers and cotton. Of course, it can be advantageously applied to the slacks manufactured by the above method.

Other than that, although not enumerated one by one, the present invention is
Based on the knowledge of those skilled in the art, it can be implemented in various modified, modified, and improved modes, and such an mode does not depart from the gist of the present invention.
Both are included within the scope of the present invention,
Needless to say.

[0043]

As is apparent from the above description, in the slacks according to the present invention, a relatively long fixing area is formed on the back side of the slacks line by the superposition of the first and second adhesive tapes. In addition to the effective fixing of the slacks line, the first adhesive tape can effectively prevent the expansion of both side parts of the slacks line, and further, Since the second adhesive tape can advantageously prevent the extension of the first adhesive tape in the width direction due to the pulling force accompanying the expansion of the both side portions,
The pulling force applied during wearing can very effectively prevent the folds forming the slacks line from being widened, so that only one adhesive tape can be attached to the back side of both sides of the slacks line. The slacks line can be satisfactorily held for a longer period of time as compared with the conventional one in which the expansion of the both side portions is simply prevented.

Further, in the slacks manufacturing method according to the present invention, the slacks line is set and the first and the second parts which effectively prevent the expansion of both side portions of the slacks line in one step. Since the gluing of the two adhesive tapes can be performed at the same time, the slacks having the above-mentioned excellent characteristics can be easily produced with a relatively small number of steps.

In the present invention, when the first and second adhesive tapes are composed of cloth adhesive tapes,
Since such an adhesive tape can be freely bendable, a good slacks line can be easily formed, and even if the adhesive tape may be brought into contact with the wearer's both feet, etc. There is an advantage that a feeling of strangeness can be suppressed as much as possible.

Further, in the present invention, when the first or second adhesive tape is formed by scattering the adhesive on one or both surfaces thereof, the amount of the adhesive used Can be adjusted arbitrarily and easily, so that when the first and second adhesive tapes are adhered to the formation site of the slacks line, excess adhesive seeps out to the peripheral part of the slacks line. As a result, the appearance of the slacks and the discomfort to the wearer can be effectively avoided.

Further, in the present invention, when the first and second adhesive tapes are composed of a heat-sensitive adhesive and a heat-shrinkable cloth, heat pressing using a steam iron or the like is performed. When setting the slacks line, the first and second adhesive tapes can be heat-sensitively adhered to the back sides of both side portions of the slacks line at the same time, whereby the slacks having the above-mentioned excellent characteristics can be obtained. The manufacturing process can be advantageously simplified, and as a result, the manufacturability of the slacks or the workability of the slacks can be effectively improved, and at the same time, the fabric forming the adhesive tape at the time of hot pressing. The heat shrinkage of the adhesive causes a tensile stress to be generated in each adhesive tape, which acts as a force that prevents the expansion of both sides of the slacks line. In fixed or of with each other to effectively contribute to the holding.

Furthermore, in the present invention, one of the first and second adhesive tapes has a portion which does not overlap each other on at least one side in the width direction thereof, and in the portion which does not overlap each other. When bonded to the back sides of both side portions of the slacks line, it is possible to make it difficult for the lines of the end portions of the first and second adhesive tapes that are overlapped to appear on the front sides of the both side portions, It is possible to effectively prevent the deterioration of the appearance due to the adhesion of the adhesive tapes.

In the method of manufacturing a slacks according to the present invention, when the first and second adhesive tapes are arranged at predetermined positions, the first adhesive is applied to the back sides of both side parts of the slacks line forming part of the leg part. The tape is temporarily adhered to the first adhesive tape so that the tape does not come off from the back side and the second adhesive tape does not come off from the first adhesive tape. In this case, it is possible to effectively prevent the first and second adhesive tapes from dropping from a predetermined position during the subsequent bending or pressing process without any special operation. As a result, a slacks having a slacks line with excellent durability can be manufactured more easily and efficiently.
