Description

[Detailed Description of the Invention] Industrial Field of Application The present invention relates to an improvement of a pleated curtain made of a fabric in which fold lines are formed by a woven structure.

Conventional technology and its problems It is possible to create curtains made of textiles without sacrificing their texture, flexibility, drapability, or light-shielding properties, and in addition, there are special restrictions on the type of fiber material used to form the curtains. In order to be able to fold the fabric along a predetermined crease line without having to use a folded fabric, the fold line that can be folded by itself can be permanently maintained. The pleated curtains made by the inventor of the present invention have already been proposed and are publicly known (Jikkosho).
56-53756). The main point of the structure of this previously proposed pleated curtain is that it is a satin weave or twill weave fabric with multiple weft or more double weft or warp or more double wefts. A woven fabric that is organized so that each weft group or each warp group forming each layer such as a surface layer, a back layer, a medium layer, etc. alternates their layer positions at the same time with the required number of dividing lines along the weft. Due to its organizational structure, the division line itself functioned as a fold line.

However, the structure of the previously proposed pleated curtain basically satisfies most of the desired features, and is superior to any other conventional pleated curtain in terms of overall function and texture. Although it was far superior in comparison, subsequent research revealed that there were still problems that needed to be improved, particularly in terms of folding function and light-shielding properties at the crease line. That is, according to the structure, the division line as a fold line along the warp or weft is defined by the fact that each group of wefts or each group of warps forming each layer changes their layer positions substantially all at once.
Each group of wefts or each group of warps is formed exactly linearly as a crossover of layer position change between two adjacent warps or wefts at a predetermined position. In this way, each group of wefts or each group of warp threads can be linearly transformed by simultaneously changing the layer position between two adjacent warp threads or weft threads. If the fold line is simply formed, it lacks flexibility and width margin, and in relation to the thickness of the multiple tissue, it is necessary to have the function of being able to smoothly fold the fold line to a completely folded state. It was a bit unreasonable, and there was still some difficulty in perfecting the folding function. At the fold line, each group of wefts or each group of warps simultaneously changes the layer position between two adjacent warps or wefts, so that there is no change between the two warps or wefts. The particles separated to some extent, creating a slight gap, and therefore were still insufficient to obtain complete light-shielding properties.

Technical Issues of the Present Invention In view of the above-mentioned problems with the pleated curtains already proposed, the purpose of the present invention is to improve the folding function and light-shielding properties at the fold lines. .

Technical Means of the Present Invention For this purpose, the present invention systematically modifies the crease lines to provide a suitable width and flexibility for easy folding, and to create a plain weave texture so as not to create gaps. It is something.

In other words, the present invention consists of a fabric woven with a plurality of partition line parts extending in the direction along the warp or weft, which are arranged at intervals, and a plurality of flat areas defined by these partition line parts. , a pleated curtain in which the plurality of division line portions are formed as fold lines capable of folding by themselves due to the weave structure of the fabric, wherein each of the plurality of division line portions corresponds to a plurality of warps or wefts. a single plain weave with a width, and each of the plurality of flat areas is a weft double weave in which two groups of warp or weft yarns form a front weave and a back weave, respectively, at least in a portion adjacent to the division line portion; It is characterized by being structured in a woven or warp double weave.

Effects of the present invention According to the present invention, each division line portion as a fold line is a weave line of a single plain weave having a width equivalent to a plurality of warps or wefts, so that the thickness of the double weave in each flat area is It is formed to have a suitable width and flexibility as a crease so that it can be folded smoothly into a completely folded state, and it is extremely easy to fold and has a very high folding function. Moreover, since the division line portion as the fold line is woven into the tissue muscle of the plain weave, there is no separation between specific adjacent warp or weft yarns, and there is no gap between them. The light-shielding property can be completely eliminated.

Here, with regard to making the division line part as a fold line into a single plain weave tissue line, the number of warps or wefts that define the width of the tissue line should be less than two. to do,
Therefore, it is not unthinkable to use only one strand, but in such a case, it would be structurally incomplete as a plain weave, and the so-called double woven parts of the adjacent flat areas would not fit together, and the boundary would not be clear. Not only is there little room for tissue muscle width, but also
A good result cannot be expected because the main threads are in a shape where the neighboring threads are gathered together, creating tissue gaps.
Conversely, if the number is too large, the width of the plain weave to be formed becomes too large than necessary as a crease line, making it less likely to break, and
The difference in weave shrinkage between the plain weave and the double weave in the flat area increases, which has the disadvantage of not only making it difficult to create a neat texture, but also making it difficult to weave as threads break easily. You can't expect good results. In this sense, it is practical to set the number to at least two, and up to about six at most.

Embodiments of the present invention Examples of the present invention will be described below with reference to the drawings.

FIGS. 1 and 2 show a preferred embodiment of the structure of the fabric constituting the pleated curtain according to the present invention. The structure of this fabric is basically a weft double weave, especially a weft double double sided weave, in which the first weft 2 and the second weft 3 are alternately inserted into the warp 1. Both sides have 8 sheets organized in a latitude and oblique pattern. In the structure of this woven fabric, the symbol L is designated as the part sandwiched between two dashed lines in the center of the drawing, which forms a predetermined partition line along the warp 1, so that the woven fabric is divided into predetermined widths. In the division line part shown below, each weft group (group) of the front weft and back weft, that is, the first two groups of wefts and the second three groups of wefts, are organized so that their front and back positions are alternated with each other. be. In this way, flat areas A and B of the weft double weave are woven on both sides of the division line portion L, with the front weft and back weft formed by mutually different groups of weft yarns. That is, in the flat area A on the left side of the division line portion L in the drawing, the first weft 2 is replaced by the warp 1.
When viewed from the front side, it is woven into a 1.7 right-hand diagonal weave to form the front weave, and the second weft 3 is wefted with the warp 1 to a 7.1 right-hand diagonal pattern when viewed from the front side, and therefore, when viewed from the back side, it is 1.7 right-hand diagonal weave.
7 It is organized in a diagonal pattern going up to the left as a back organization. On the other hand, in the flat area B on the right side of the lot line part L,
The front and back relationship of the first weft 2 and the second weft 3 is reversed, and the second weft 3 is 1.7 when viewed from the front side with the warp 1.
The first weft 2 is wefted in a right-hand diagonal weave to form the front weave, and the first weft 2 is wefted with the warp 1 in a 7/1 right-hand diagonal when viewed from the front side, and accordingly, a 1.7 left-hand diagonal when viewed from the back side. It is a secret organization. In the structure of this woven fabric, in particular, the division line portion L where the first weft 2 and the second weft 3 alternate in front and back relationship is compared to the two adjacent warp 1. All the wefts of the first weft 2 and the second weft 3 are woven into a plain weave, and are woven into a plain weave with a single layer and a slight weave width W.

Therefore, the fabric organized in this way is a double weft weave in which the first two groups of weft yarns and the second three groups of weft yarns float equally long on the front and back sides, and there is a flat weave on the left side with the dividing line portion L as the border. In addition to the fact that the first two groups of wefts and the second three groups of wefts alternate the front and back weave positions in the area A and the flat area B on the right side, the division line portion L is a single plain weave weave. As a result, it has the function of a crease line that easily breaks on its own. in this case,
In particular, according to this structure, the division line portion L as a fold line is formed as a plain weave structure in which all the wefts of the first weft 2 and the second weft 3 are woven into two adjacent warp threads 1 into a plain weave. Due to the woven structure, it has an appropriate width W that is neither wide nor narrow, not as a complete line but as a fold, and is thinner and more flexible than the double woven parts A and B, and has warp and weft. It is formed so that there is no tissue gap between the two. Therefore, the division line part L as the fold line is extremely easy to break due to its flexibility, and its width W has a folding function that allows it to be smoothly folded to a completely folded state with respect to the thickness of the double woven part A. The light-shielding property is very high, and the light-shielding property is perfect because no tissue gaps are created.

In this way, a fabric with such a structure can make full use of the texture and flexibility of a fabric, has excellent drapability, and can of course fold on its own at predetermined fold lines that are systematically formed and last forever. Compared to conventionally proposed products, the folding function of the crease lines is significantly improved, and a pleated curtain with perfect light-shielding properties can be obtained, and an example thereof is shown in FIG. That is, the pleated curtain 4 shown in FIG. 3 is woven with dividing lines such that the left flat area A and the right flat area B in the structure shown in FIGS. 1 and 2 are alternately defined by a predetermined width. The part L is made of a fabric formed by weaving a required number of parts at predetermined intervals, and a rotatable hanging tool 5 is provided at the middle of the upper edge of each flat area A, B, and the hanging tool 5 is attached along the curtain rail 6. It is suspended so that it can slide freely. According to this pleated curtain 4, when folding and opening is performed by sliding the hanging tools 5 along the curtain rail 6, each partition line portion L becomes a fold line by itself and is folded and opened in a zigzag manner. However, this can be done very smoothly because the folding function of each division line portion L is very high as described above, and especially when folded, the flat areas A and B, which are double weaves, can be folded. can be smoothly and neatly folded into a completely folded state in which they are joined face-to-face with each other. Moreover, there is no tissue gap at each division line portion L as a fold line, and complete light-shielding properties can be obtained.

However, the pleated curtain with the above configuration is
As it is made of textiles, it has excellent texture and flexibility, has excellent drapability, has a very high folding function that can be folded by itself at the permanently lasting crease lines formed in a predetermined structure, and has perfect light blocking properties. It can be applied to various places as blinds, curtains, partitions, etc., and is extremely good in terms of both appearance and functionality.
Although not shown, by equipping and using an opening/closing device that moves each hanging tool 5 using an appropriate mechanism such as a motor, the pleated curtain 4 can be automatically and smoothly opened by remote control. It can be folded and opened neatly, and thus can be used particularly well as a window curtain for automobiles, for example.

In the above-described pleated curtain 4, although it is not necessary, it is even better if each division line portion L serving as a fold line is provided with alternating bends in the folding direction, for example, by pressing. In addition, although it is not necessary because the folding mechanism is high, in order to further ensure the folding action, in some cases, it is necessary to set the lower or upper edge of each of the double-woven parts A and B to straightness, for example. Some degree of rigidity can be imparted by attaching a suitable weight or core material 7 by sewing or the like. In addition, any fiber material can be used for the warp 1 and weft 2, 3 of the textile structure that constitutes this pleated curtain 4, depending on the texture desired for this curtain and the place where it is applied. Using 100% flame retardant materials, it can be adapted for use as curtains in fire service regulated areas. To give an example of the type of yarn and texture density used in a very ordinary case, all yarns are flame-retardant acrylic yarn (Kanekalon) such as a polymer of acrylonitrile and vinyl chloride, and warp 1 is made of cotton number. 3
The first weft yarn 2 and the second yarn 3 are both cotton count 30/2, and the fold density is 50 yarns/inch. Book/
In this way, good results can be obtained. In addition, the organization's
By making the weft yarn 2 and the second weft yarn 3 of different colors, both flat areas A and B of the front and back cottons have different colors from each other,
You can obtain beautiful curtains with a striped pattern of alternating colors. Furthermore, it is possible to partially change the structure in both flat areas A and B to create patterns in various pattern designs, and in this way, it is possible to obtain curtains that are even more beautiful in design and rich in variety. I can do it.

In the embodiment described above, the number of warp threads 1 applied to the division line portion L as a fold line is woven into the tissue muscle of the plain weave to be two adjacent. In relation to the fact that the flat areas A and B on both sides of the division line L are constructed of a double weave with different groups of weft yarns alternating the front and back sides, both sides of the plain weave weave The weave boundary between the flat areas A and B can be clear, the difference in weaving shrinkage rate between them does not become large, and the weave can be neatly organized, and in particular, the width W as a fold is optimal, neither wide nor narrow. It is the best in all things. However, regarding the number of warp yarns 1 to be applied, if one warp yarn is used, there is hardly any margin for the width W as a fold, and good results cannot be obtained because tissue gaps may be created. If you increase the number, the width W as a fold becomes too large than necessary, making it difficult to fold, and the difference in weaving shrinkage rate also increases, making it difficult to obtain a neat texture. As a practical range, it is possible to have at most six lines, and this point is as described above. Therefore, as a practical range, we will consider the typical number of warp threads 1 applied to the plain weave texture of the division line portion L in the same 8-ply diagonal weft weave as in Figures 1 and 2. FIGS. 4 and 5 show an embodiment in which there are three adjacent wires, and FIGS. 6 and 7 show an embodiment in which there are a maximum of six adjacent wires. In these embodiments, in the case of the structure shown in FIGS. 4 and 5 in which three adjacent warp threads 1 are applied to the plain weave tissue muscle of the division line portion L, as is clear from the drawings, , the plain weave structure is a double weave, and the weft groups are turned inside out and do not meet with the diagonal structure of both flat areas A and B, resulting in areas where the boundaries are not clear. One of the three warp threads 1 applied is wasted, resulting in a structure that is almost the same as the two warp threads shown in FIGS. 1 and 2, and even if it can be put to practical use, it is not very good. This point is the same as long as the number of applied warp threads 1 is set to an odd number.For example, although not shown in the drawings, a structure in which the number of applied warp threads is set to 5 is almost the same as a structure in which the number is set to 4. It will remain unchanged. In this regard, if the front and back textures of the double weave in the flat areas A and B are formed by different groups of weft yarns (or warp yarns in the case of warp double weave), the plain weave texture in the division line portion L It is preferable that the number of warp threads (or weft threads) that define the width of the stripes is an even number. Figures 6 and 7 also show that the number of warp threads 1 applied is 6 for the adjacent warp threads.
In the case of the tissue shown in the figure, the tissue striations of the plain weave at the division line portion L are slightly larger than necessary as folds in the width W, although there is no practical problem, and both flat areas A and B The difference in weave shrinkage rate between the two and Although not shown in the drawings, this point is also not very preferable in the case of a structure in which the number of warp threads 1 is five or four, even if the degree is less.

In addition, in the example of the structure explained above, the flat areas A and B are of a weft double weave, and the front and back sides have 8 weft oblique patterns, but the weft pattern of the front and back surfaces of the weft double weave is In addition to the 8-sheet latitude-oblique text, it can be made into various latitude-oblique texts, and can also be made into various weft-satin patterns. As an example, typical examples are 4-sheet latitude oblique pattern, 5-sheet latitude oblique pattern, 8-sheet weft satin pattern, and 5-sheet weft satin pattern as shown in Figures 8 and 9.
10 and 11, respectively. In all of the embodiments shown in FIGS. 8 to 11, the number of warp threads 1 applied to the plain weave tissue muscles of the division line portion L is two adjacent ones, as in the case of the embodiment shown in FIG. 1. Shown as

In addition, all of the examples of the structures explained above are double weft weaves, but due to the nature of the fabric, it is possible to naturally switch the warp and weft and implement it as a double weft weave. Of course. That is, in the organization of the illustrated embodiment that has been described,
The warp 1 is the weft, and the first weft 2 and the second weft 3 are
The warp and weft are replaced as they are so that they are the first warp and the second warp, and the weft diagonal pattern and weft satin are changed to warp diagonal pattern and warp satin, and the division line part L runs along the weft. It can be woven and formed as a plain weave structure in which all the warp threads are woven into a plain weave with two to several weft threads.

In addition, in the present invention, each flat area does not necessarily need to be entirely double woven; it is only necessary that at least the portion adjacent to the division line portion of the plain weave tissue muscle serving as the fold line be double woven. FIG. 12 shows an example of such a case, in which both flat areas A and B are made double weave to an appropriate width in parts a ₁ and b ₁ adjacent to the division line part L, and the remaining middle part It has a ₂ and b ₂ in an appropriate structure such as a single diagonal.

In addition, in the present invention, the double weave in each flat area is not necessarily defined by the division line part of the plain weave tissue muscle as the fold line, whether it is made entirely or partially as shown in Fig. 12 above. The threads of the front and back textures alternate at the division line part of the plain weave weave as the front texture, that is, the front and back textures are formed by different groups of wefts or warps on both sides of the division line. It is not necessary to do so, and it may be formed by the same group of weft or warp yarns without such alternation. FIG. 13 shows an example of such a case, in which the weft double weaves of flat areas A and B on both sides of the division line portion L are both surface-woven using the same group of first weft yarns 2. A layer is formed and a group of second weft yarns 3 is woven to form a backing layer. In addition,
In this way, when the front weave and back weave of a double weave in the flat area on both sides of the division line are formed by the same group of weft yarns (or warp yarns in the case of a warp double weave), The number of warp threads 1 (weft yarns in case of warp double weave and the partition line part is in the weft direction) that defines the width W of the division line part L of the plain weave tissue muscle is not an even number as described above, but on the contrary, it is 3. It is preferable to use an odd number of lines, such as one or five, because it reduces the chance of getting confused at the organizational boundary and makes the boundary clear.

Furthermore, the embodiments described above with reference to FIGS. 1 and 2 and FIGS. 4 to 13 are the front and back textures of the weft double weave or warp double weave in each flat area. The group of weft or warp yarns that make up the yarn are yarns that run in a direction that intersects the direction in which the division line part extends, but it is also possible to use threads that run in the same direction as the direction in which the division line part extends. . 14th
The figure shows an example of this, in which the division line portion L extends in the direction along the warp 1, and the double weave in the flat areas A and B is a warp double weave. Regarding this,
Although not shown in the drawings, it is of course possible to change the warp and weft yarns so that the division lines extend in the direction along the warp, and change the double weave in the flat area to a weft double weave. In this case, for example, the warp or weft yarns that make up the double weave in the flat area can be colored in different groups in each area, giving the advantage of being able to create a variety of color patterns on the front and back sides.

Effects of the invention As explained above, according to the invention, in particular, each division line part as a fold line is made into a plain weave structure having a width equal to a plurality of warps or wefts. The problem of the unsatisfactory folding function and light-shielding property at the crease line is solved, and there is an effect that the folding function and light-shielding property can be further improved.
