Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a pleating method for producing cloth products such as pleated clothes.

[0002]

2. Description of the Related Art Conventionally, pleating clothes has been performed by various methods. In recent years, it has been practiced not only to partially apply the pleats but also to apply pleating to the entire clothes. Have been done.

As a specific technique for partially performing pleating, for example, Japanese Unexamined Patent Publication No. Hei 8-218213 discloses "wrinkled garment and manufacturing method thereof".
There is. According to this conventional technique, as described in paragraphs 13 and 14 of the above-mentioned publication, "... first, the cloth is cut into a predetermined shape and sewn to make it into clothes, and then the wrinkles of the cloth constituting the clothes are formed. A seam pattern is formed by using a contractible water-soluble thread in a region to be processed (the above paragraphs 13 and 14) ... (this) cloth is immersed in water to contract the contractible water-soluble thread. Then, the wrinkles generated on the fabric are thermally fixed ... ".

However, according to the study of the present inventors, this conventional technique has the following disadvantages. That is, in the above-mentioned technology, since the cloth tailored to the clothes is subjected to wrinkle processing, it is very difficult to finish the cloth in anticipation of "wrinkles" (in some cases, other parts that do not require wrinkle processing). Is drawn in after the wrinkle processing to cause wrinkles).

On the other hand, as a technique for pleating the entire garment, for example, there is a "method of producing graphic pleats" as proposed in Japanese Patent Application Laid-Open No. Hei 10-168747. As described in the front page of the above publication, the processing method disclosed in this publication has a problem of "creating a pattern by ups and downs of a fabric or a needle hole embroidered with a sewing machine or jacquard". "A laminate 100 is obtained by laminating a thermoplastic material or semi-finished product 2 on a heat-shrinkable sheet 1, and sewing the laminate 100 with a water-soluble thread 5 in a desired pattern. Is heated, a hot water bath is applied to dissolve the water-soluble thread 5, and the heat-shrinkable sheet 1 and the fabric or semi-finished product 2 are peeled off and dried. " Is what you do.

According to the technique disclosed in Japanese Patent Application Laid-Open No. H10-168747, there is almost no problem in performing the above-described partial wrinkling, but the following points are considered to be problems.

In the technique disclosed in Japanese Patent Application Laid-Open No. 10-168747, as described in paragraphs 14 to 16, a laminate obtained by sewing a sheet and a fabric or a semi-finished product with a water-soluble thread is used. Is heated for several tens of seconds by being sandwiched between rollers heated to such an extent that it does not hurt. In this case, the “feed” of the laminate between the rollers is performed by sandwiching the two rollers, so that there is almost no gap between the laminate and the rollers. In other words, "wrinkles"
It is considered that sufficient “wrinkle processing” cannot be performed because “extra space” for “shrinkage” that causes “shrinkage” is not provided between both rollers.

In other words, in order to pleate a flat cloth or the like by thermal contraction of the sheet, fine irregularities must be formed in the cloth or the like in accordance with the thermal contraction of the sheet. In order to form the unevenness, there must be a space for the unevenness on at least one side of a flat cloth or the like. Nevertheless, in this prior art, since both sides of the laminate are sandwiched between two rollers, there is almost no room for so-called three-dimensional irregularities.

In addition, the fact that the laminate is sandwiched and fed by the rollers means that there is a possibility that wrinkling in the axial direction of the rollers may not be sufficiently performed. This is because the sheet is sandwiched between the rollers before shrinking, so that even if the laminate is shrunk, the pinching force of the roller prevents the shrinking action. Therefore, it is considered that the processing in the “radial direction” of the roller is not always square, and the wrinkling in the “axial direction” is not sufficient.

The present inventors have conducted various studies on how to solve the above-mentioned difficulties of the prior art, and as a result, completed the present invention.

[0011]

SUMMARY OF THE INVENTION The present invention has been made based on the above circumstances, and the problem to be solved is to make sure that the expected pleating process is performed in a manner that evenly causes shrinkage. Is to be able to do it.

That is, the object of the present invention is as follows.
When performing pleating using a heat-shrinkable sheet, a pleating method that ensures reliable pleating of fabrics and semi-finished products by ensuring space for “shrinkage” To provide.

[0013]

Means for Solving the Problems In order to solve the above problems, first, means according to the first aspect of the present invention will be described with reference numerals used in the following description of embodiments. "A cloth 12 or semi-finished product 11 is overlaid on a heat-shrinkable sheet 12 and partially sewn with a water-soluble thread 13 to form a laminate 10. 21 and at least one of the table plate 21 and the press plate 22 with a predetermined gap C between the laminate 10 and at least the press plate 22. The sheet 12 is shrunk in the gap C by heat, whereby the cloth or semi-finished product 11 integrated with the sheet 12 is shrunk and pleated. Sheet 12 by dissolving the soluble yarn 13
And a pleating method for fabric products in which the dough or the semi-finished product 11 is dried.

That is, the invention according to claim 1 is characterized in that the laminate described in the above-mentioned Japanese Patent Application Laid-Open No. H10-168747,
In other words, the heat processing of the laminated body 10 in which the fabric or the semi-finished product 11 is integrated with the water-soluble yarn 13 on the sheet 12 which contracts when heated is the same as the above-described conventional technique, How to make a predetermined gap C exist between the laminate 10 and at least the press plate 22,
There is a great difference in that the sheet 12 contracts in the gap C.

The laminate 10 and the press plate 2 of the press machine 20
2 has a gap C between the table plate 2
When the sheet 12 shrinks due to the heat from the press plate 1 or the press plate 22, irregularities are surely formed on the non-shrinkable fabric or semi-finished product 11. That is, the sheet 12 shrinks in a substantially planar manner due to the heating, but the non-shrinkable fabric or semi-finished product 11 partially integrated with the sheet 12 by the water-soluble yarn 13.
In other words, irregularities are generated in a portion that is not sewn to the sheet 12 according to the heat shrinkage of the sheet 12.

The irregularities of the fabric or semi-finished product 11 formed here are fixed by the heat supplied from the table plate 21 or the press plate 22. Needless to say, in order to perform the fixing by heat, the fabric or semi-finished product 11 may be formed of chemical fibers. Alternatively, the irregularities may be fixed by increasing the time for heating. The heating by the press machine 20 is usually performed at 170 ° C. to 190 ° C.
Although heating is performed using steam at ° C., heating using electric heat instead of steam may be used, or steam and electric heat may be used in combination.

As described later, the heat-shrinkable sheet 12 may be a synthetic resin sheet as exemplified in Japanese Patent Application Laid-Open No. 10-168747. It may be a woven fabric using a yarn formed of a conductive material. As the contraction rate of the sheet 12,
If it is less than this range, sufficient pleating cannot be performed, and if it is larger than this range, it is difficult to obtain beautiful pleats.

As the water-soluble yarn 13 for integrating the cloth 12 or the semi-finished product 11 with the sheet 12, it is preferable to use polyvinyl alcohol as a main material, and from the viewpoint of processability, it can be dissolved in warm water. Is suitable. The sewing with the water-soluble thread 13 may be partially performed as shown in FIG. Rather, it is more convenient to perform the pleating process if there are a lot of free fabrics or semi-finished products 11 for the sheet 12. This is because irregularities occur in the portion of the fabric or semi-finished product 11 that is free with respect to the heat-shrinkable sheet 12, which becomes pleats. Conversely, the sewn portion of the water-soluble thread 13 determines the range in which the pleating process is performed. By utilizing this, the position and shape of the pleat can be determined.

After the pleating process, the water-soluble yarn 13 is dissolved by immersing it in warm water, thereby freeing the pleated fabric or semi-finished product 11. This dough or semi-finished product 11 is then subjected to a process such as drying to be used as a material for forming a fabric product, as in the conventional technology.

Therefore, in the pleating method according to the first aspect, since the gap C is positively formed between the pleating method and the table plate 21 or the press plate 22, the cloth with beautiful pleats is provided. The product can be reliably sewn.

[0021] In order to solve the above-mentioned problem, a means adopted by the invention according to claim 2 is a method similar to that described above, wherein "a cloth 12 or a semi-finished product 11 is laminated on a heat-shrinkable sheet 12, The laminated body 10 is formed by performing partial sewing with the water-soluble thread 13, and the laminated body 10 is disposed between the table plate 21 and the press plate 22. And the sheet 12 is contracted in the gap C by the heat supplied from at least one of the table plate 21 and the press plate 22 by providing a predetermined gap C between
After shrinking the fabric or semi-finished product 11 integrated with the sheet 12, the press plate 22 is further pressed against the table plate 21 to perform pleating, and then the water-soluble yarn 13 is dissolved to obtain a sheet. 12 is a pleating method for fabric products in which the dough or semi-finished product 11 is dried.

That is, in the pleating method according to the second aspect, in the pleating method according to the first aspect, the dough or semi-finished product 11 pleated between the table plate 21 and the press plate 22 of the press machine 20 is used. In the future, a process of pressing the dough or semi-finished product 11 by the press plate 22 will be added.

By adding the pressing step using the press plate 22, it is possible to complete the pleating of a material whose pleats are not sufficiently fixed only by heating between the press machines 20. . That is, when the fixing of the irregularities formed on the fabric or the semi-finished product 11 is not sufficiently performed due to the heat shrinkage of the sheet 12 and the heating between the press machines 20, the pressing by the press plate 22, that is, the heating is performed. By adding the step of applying pressure, beautiful pleat processing is completed.

[0024] In order to solve the above-mentioned problem, a means adopted by the invention according to claim 3 is a method similar to that described above, wherein a cloth 12 or a semi-finished product 11 is superimposed on a heat-shrinkable sheet 12, The laminated body 10 is formed by performing partial sewing with the water-soluble thread 13, and the laminated body 10 is arranged between the table plate 21 and the press plate 22,
A predetermined gap C exists between the laminated body 10 and at least the press plate 22, and the sheet 12 shrinks in the gap C by heat supplied from at least one of the table plate 21 and the press plate 22. By letting
The dough or semi-finished product 11 integrated with the sheet 12 is contracted and pleated, and the pleated dough or semi-finished product 11 is inserted into a heating pot together with the sheet 12 and heated. A pleating method for a cloth product, wherein the yarn 13 is melted, the sheet 12 is removed, and the dough or the semi-finished product 11 is dried.

That is, the pleating method according to the third aspect is the pleating method according to the first aspect,
A large number of pleated fabrics or semi-finished products 11 are stacked between the table plate 21 and the press plate 22 of the press machine 20 in consideration of efficiency while the sheet 12 is attached, and these are inserted into the heating pot and heated again. It is a process to which a process is added. This heating pot is used when pleating a cloth folded between two sheets of paper, and stabilizes the pleats.

After heating in the heating kettle, the water-soluble yarn 13 is dissolved, the sheet 12 is removed, and the dough or semi-finished product 11 is removed.
Is the same as in the pleating method of claim 1 or 2 described above.

Therefore, the pleating method according to the third aspect of the present invention is similar to that of the second aspect described above.
When a material that cannot be sufficiently pleated only by heating the laminate 10 with a temperature of 0 is used, a sufficiently stabilized pleat can be formed.

The heating step by the heating pot in claim 3 can be added to the pleating method according to claim 1 or 2. In this case, a plurality of pleat stabilization operations are performed, so that more stable pleat processing can be performed.

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a perspective view showing a pleating method according to a first embodiment of the present invention; Since the invention substantially includes all of the inventions, the embodiment will be mainly described below.

FIG. 1 shows a laminate 10 which is a premise for carrying out the present invention.
As shown in FIG. 1A, the heat-shrinkable sheet 12 and the dough or semi-finished product 11 placed thereon are
It is partially integrated by the water-soluble yarn 13.
The term "partial" means that the sewn with the water-soluble thread 13 is made to have a large lattice shape, as shown in FIG. 1
This means that the free portion for one sheet 12 is made as large as possible. In other words, the sewing by the water-soluble thread 13 can be freely set according to the pleated design in addition to the above-described lattice shape.

The dough or semi-finished product 11 that constitutes the laminate 10 and is to be a cloth product is preferably one that can be easily pleated, and one that is mainly composed of chemical fibers is suitable. Of course, in the case of a method having a step for stabilizing the pleats 30 as in the pleating method of claims 2 and 3, the fabric or semi-finished product 11 may be made of a material other than chemical fibers, or It may be one using a blended material.

As described above, the sheet 12 has a thickness of 50% to 8%.
Any material may be used as long as it has a two-dimensional shrinkage of about 0%, and it may be a synthetic resin sheet or a woven fabric. For example, not only vinyl chloride or polypropylene sheet and film material but also polyester 1
A fabric using 00% yarn, a fabric using polypropylene fiber, or the like is suitable as a material constituting the sheet 12. In the present embodiment, polyester 100 having a shrinkage of 60% is employed.

On this sheet 12, dough or semi-finished product 11
As the water-soluble thread 13 for partially integrating the fabric or the semi-finished product 11 and the sheet 12 and a material that can be sufficiently dissolved by dipping in hot water. , May be anything as long as it can meet at least two conditions of
In the present embodiment, a material mainly composed of polyvinyl alcohol is employed.

Now, the laminate 10 constructed as described above
Is a table plate 21 of a press machine 20 as shown in FIG.
It is placed on top and heated by a press plate 22 that descends from above. This heating is performed in this embodiment.
Although the steam of 170 ° C. to 190 ° C. is ejected from the table plate 21 and the press plate 22 toward the laminate 10, the steam may be applied by electric heating without using the steam. Of course, heating using both steam and electric heat may be performed.

Further, in the present embodiment, heating is performed on both surfaces of the table plate 21 and the press plate 22 to improve the efficiency of heat conduction and improve workability. Needless to say, it may be performed by one of the press 21 and the press plate 22.

What is important in performing the pleating by the press machine 20 is that the press plate 22 is not completely pressed toward the table plate 21 side, as shown in FIG.
This is to keep the gap C between the laminate 10 and the press plate 22. In this embodiment, the specific size of the gap C is 1.5 cm.
3 can be freely set according to the sewing interval, the thickness of the cloth or the semi-finished product 11, and the shrinkage ratio of the sheet 12.

The gap C can be easily set by a stopper that defines the position at which the press plate 22 descends with respect to the table plate 21. By removing the stopper, the gap C can be eliminated. That is, the gap C
When it is desired to stabilize the pleats 30 by further pressing the pleats 30 once formed in the presence of the pleats 30 by the press plate 22, the gap C may be released after the pleats 30 are formed. . This is a requirement of the pleating method of the second aspect.

In the pleating method of the present embodiment, the pleated dough or semi-finished product 11 and the sheet 12 are further inserted into a heating pot, and the whole is heated to stabilize each pleat 30. Like that. The insertion into the heating pot may be performed after the pleats 30 are formed in the first or second aspect.

The fabric or semi-finished product 11 on which the pleats 30 have been formed as described above must be removed from the sheet 12, but in the present embodiment, the entire laminate 10 is placed in hot water at about 40 ° C. to 80 ° C. The water-soluble yarn 13 is dissolved by immersion in the fabric 12, thereby separating the fabric or semi-finished product 11 from the sheet 12. Of course, the dough or semi-finished product 11 separated from the sheet 12
Will be dried after performing a predetermined washing if necessary.

As a result, the dough or semi-finished product 11
Many pleats 30 as shown in FIG. 3A are formed in a state of beautifully intersecting, and when viewed in cross section, each pleat 30 is formed as shown in FIG. 3B. Each is formed as an upper and lower part.

Therefore, if a cloth product is formed using the cloth or semi-finished product 11 on which the pleats 30 are formed as shown in FIG. 3, the design and the feeling are very excellent. It can be.
