2. Description of the Related Art Conventionally, as a curtain cloth used for a roll curtain, one having flexibility and having an appropriate tension and elasticity capable of being smoothly wound is preferably used. Such a curtain fabric can be obtained by coating a soft fabric without tension with a resin (so-called hard finish) or by covering with a transparent film. Further, such coating treatment or coating treatment is also performed when the curtain fabric is a woven fabric or a non-woven fabric in order to prevent fraying of the side edges.

On the other hand, as a conventional shade curtain,
Folded folds (refraction part) that occur when the curtain is rolled up
In order to make the appearance look beautiful, there is one in which a bar-shaped member (called a shaper bar or a tack bar) is attached to the fold portion and this is lifted by a lifting string to make the folds regular (Japanese Patent Laid-Open No. 07-051156, Kaihei 9-2219
69, etc.). Further, when the curtain fabric is a woven fabric or a non-woven fabric, the curtain is subjected to three-roll sewing, the above-mentioned coating treatment, etc. in order to prevent the fray of the side edges of the fabric.

[0004]

However, the types of curtain fabrics having tension and elasticity suitable for conventional roll curtains are limited, and the types of roll curtain products cannot be sufficiently expanded. In addition, when the curtain fabric is subjected to a coating treatment or a coating treatment, the original characteristics (texture, texture, texture, aesthetics, etc.) of the cloth of the curtain cloth are impaired, and such original characteristics of the cloth are utilized. I couldn't get a roll curtain. Moreover, the coating process and the coating process are usually performed in dye lot units, and when the required amount of curtain fabric is not so large, it tends to be difficult to produce only the required amount in smaller lot units. .

On the other hand, in the conventional shade curtain, a rod-shaped member and a bag portion or member for attaching the rod-shaped member to the curtain are required, and sewing work for this bag portion and attachment work for the rod-shaped member are required. It was Therefore, the number of parts and the number of manufacturing steps are increased, resulting in an increase in cost. Further, there is a problem that the shadow of the rod-shaped member or the seam is projected on the front side of the curtain, which impairs the aesthetic appearance of the curtain. In particular, in the case of a light-shielding curtain, it is necessary to sew it so that light leakage does not occur, which is very troublesome. In addition, the edge of the curtain becomes thicker than other parts due to three roll sewing and coating treatment,
Resistance occurred when raising and lowering the curtain. In addition, since the weight of the entire curtain is increased by the rod-shaped member, it is not possible to sufficiently enhance the operability when moving up and down the curtain.

Therefore, in view of the above conventional problems, the present invention provides a roll carte which does not impair the original characteristics of the fabric of the curtain fabric, and which has flexibility and moderate tension.
It is intended to provide a curtain fabric for a curtain or shade curtain . Another object of the present invention is to provide a roll curtain capable of expanding the types of products using curtain fabrics that have been difficult to use in the past and enhancing decorativeness. Further, it is an object of the present invention to provide a shade curtain that can improve aesthetics and reduce costs.

In order to solve the above-mentioned problems, the inventors of the present invention have conducted extensive studies and performed a coating treatment or a coating treatment on a flexible curtain fabric to provide good flexibility while maintaining flexibility. The inventors have found that they are given and have reached the present invention. That is, the roll curtain or sheave according to the present invention.
The curtain fabric for a drape is characterized in that a surface fabric made of a woven or knitted fabric and an interlining made of a woven fabric, a knitted fabric, a non-woven fabric or a resin film are laminated with a heat-fusible material. Such a roll curtain or shade car
According to the curtain fabric for ten , the laminated outer material and interlining material limit the expansion and contraction of each other, so even if the outer material alone has high flexibility and large expansion and contraction, it can be used as a curtain material such as a roll curtain. Suitable flexibility and moderate stiffness are obtained. Therefore, the curtain cloth which has been conventionally difficult to use for a roll curtain or the like can be used for a roll curtain or the like.
In addition, the degree of tightness can be adjusted by appropriately selecting the material and thickness of the outer material and / or the inner material. Moreover, since the conventional coating or coating is not applied, the original characteristics of the outer material are not impaired at all. Rather, the feeling of tension and stiffness can be generated, so that the decorativeness of a roll curtain or the like using the curtain fabric of the present invention can be enhanced. Also, since there is no need for conventional coating or coating,
It is possible to manufacture only the required amount in units of smaller production lots than before. In addition, both sides can be used as the front side (reversible) by using the interlining with a pattern that can be used on the front side of the curtain fabric.
Curtain fabrics can be obtained. Furthermore, since the outer fabric and the interlining are easily and firmly adhered to each other by heat-sealing the heat-fusible material, a curtain fabric having sufficient elasticity can be easily obtained. Furthermore, the heat-fusible material is preliminarily attached to the outer material and / or the interlining material by using a heat-fusible material that does not have tackiness and adhesiveness in a state where heat is not applied, for example, at room temperature. Even if it is stored, it will not adhere unnecessarily and is easy to handle. In addition, since the outer fabric and the interlining are superposed on each other after the laminating position is sufficiently adjusted and the both can be laminated, it is possible to easily manufacture a curtain fabric having a beautiful finish.

The side edge of the outer material and the side edge of the inner material are at least one of the outer material, the inner material and the heat-fusible material.
It is preferable that the two are welded together. With this configuration, the outer fabric and the interlining are integrally connected at the side edge portion of the curtain fabric, so that the fraying and the peeling of the yarn are prevented. Since the conventional three-roll sewing or coating process is unnecessary, the side edge portion of the curtain fabric is not thicker than other portions. Therefore, the curtain fabric can be suitably used for roll curtains, shade curtains, and the like. Further, since the side edges can be formed into a desired shape or a desired pattern can be decorated at the time of welding, a curtain fabric having the side edges extremely excellent in design and functionality can be obtained.

Further, when the interlining is a woven or knitted fabric, it is useful if the outer fabric and the interlining are laminated so that the directions of the respective weaves or stitches are different from each other. Even in this case, since the outer fabric and the interlining are bonded to each other and expansion and contraction in the weave or stitch direction of the outer fabric is limited, no matter how the cutting direction of the outer fabric is changed, a curtain fabric having an appropriate tension and elasticity can be obtained. can get. Therefore, the outer material having the same pattern can be cut in any direction to be used, and roll curtains having various patterns and patterns can be manufactured.

Further, the roll curtain of the present invention is a curtain made of the above curtain fabric of the present invention, and a winding end which is fixed to the base end portion of the curtain and is rotatable in both the winding direction and the sending direction of the curtain. And means. According to the roll curtain configured as described above, since the curtain has flexibility and moderate tension, the curtain is prevented from being twisted or disturbed, and the curtain in a fed state is clean and smooth by the winding means. To be wound up. Further, since the curtain cloth which has been difficult to use for the conventional roll curtain can be used, the roll curtain having various characteristics can be manufactured. In addition, since the curtain has an appropriate feeling of tension, the decorativeness as a roll curtain is significantly enhanced.

Further, a shade curtain of the present invention comprises a curtain made of the above-mentioned curtain fabric of the present invention, a support to which the base end of the curtain is fixed, and a linear member connected to the other end of the curtain. And an elevating means for elevating and lowering the curtain with a limiting means for limiting the position of the linear member. In the shade curtain configured in this manner, since the curtain has flexibility and moderate tension, the folding folds that occur when the curtain is rolled up may be disturbed or caught without using a conventional rod member. Absent. Further, since the rod-shaped member and the bag portion or the member for attaching the rod-shaped member are unnecessary, the number of parts is reduced. In addition, since it is not necessary to sew the bag portion or attach the rod-shaped member, the number of manufacturing steps can be reduced. Further, since there is no bar-shaped member and the above-mentioned sewing place, the shadow of the bar-shaped member and the seam is not projected on the front side of the curtain. In addition, since there is no rod-shaped member, the folding folds are compact and neatly organized, so that the aesthetic appearance of the shade curtain can be improved significantly. Further, even with a light-shielding curtain, there is no possibility of light leakage because there is no sewn portion. Further, since the side edge of the curtain can be welded, the side edge of the curtain does not become thick as in the conventional case, and the resistance at the time of winding can be reduced. Moreover, since the rod-shaped member is not required and the weight of the entire curtain is reduced,
The operability when rolling up the curtain is greatly enhanced.

The "outer fabric" in the curtain fabric of the present invention includes the fabrics conventionally used for curtains, and the "interlining" is at least the curtain when laminated with the outer fabric. It restricts the expansion and contraction of the outer material in the pulling direction (for example, the vertical direction). As described above, the “outer fabric” is made of a woven or knitted fabric, and the “interlining” is made of a woven fabric, a knitted fabric, a non-woven fabric or a resin film. Here, the “fabric” is a material including the above-mentioned outer material and / or interlining, and a material obtained by processing, finishing, or cutting the material. Also, "resin film" means
It is a film or sheet made of a resin and a resin composition. Further, the "linear member" in the shade curtain of the present invention is a thread, a string, a metal wire, a wire, a cord or the like, and includes a composite member composed of two or more of these.

DETAILED DESCRIPTION OF THE INVENTION Embodiments of the present invention will be described below with reference to the accompanying drawings. The same elements will be denoted by the same reference symbols, without redundant description.

FIG. 1 shows a first curtain fabric of the present invention.
It is an exploded perspective view showing an embodiment. Curtain fabric 1 shown in FIG. 1 (curtain for roll curtain or shade curtain
Fabric; curtain fabrics 2 and 5 described below, and
“Ten fabric” also refers to the roll curtain or sheaf of the present invention.
Represents a curtain fabric for a curtain. ) Is a surface material 11 made of a woven fabric and an interlining material 12 made of a woven fabric having thermoplasticity.
And are pasted together. An adhesive 13 (heat-fusible material; so-called hot melt) having heat-fusible property is substantially uniformly attached to the bonding surface of the interlining 12. This adhesive 13
Is a solid that is not tacky or adhesive at room temperature. The outer material 11 and the inner material 12 are simply and firmly adhered to each other by applying the heat from one side or both sides after superposing them.

Further, the outer material 11 is cut (so-called bias cut) so that the texture is in the diagonal direction in the drawing, and the expansion and contraction in the direction indicated by the arrow S11 is maximum.
On the other hand, the interlining 12 is cut so that the weave is in the upper, lower, left, and right directions in the drawing, and the stretchability in the direction indicated by the arrow S12 is maximized. That is, in the curtain fabric 1,
The outer fabric 11 and the interlining 12 are attached so that the respective textures are in different directions. Further, the side edges of the curtain fabric 1 are fused and welded by a known ultrasonic cut. At this time, the interlining 12 and the adhesive 13 on the side edge portion are once melted by the frictional heat applied by ultrasonic vibration, and when they are solidified, the outer fabric 11 and the interlining 12 are combined and integrated. It Further, the side edge portion of the curtain fabric 1 is cut into a desired shape by fusing and welding using this ultrasonic cut, and a pattern is provided on the front fabric 11 side. This is possible by appropriately selecting the welding roller of a known ultrasonic welding machine used for ultrasonic cutting.

According to the curtain fabric 1 thus constructed, the outer cloth 11 and the inner cloth 12 mutually limit the expansion and contraction of the other, and the expansion and contraction of the curtain cloth 1 is smaller than the expansion and contraction of the outer cloth 11 alone. Become. As a result, the curtain fabric 1
The curtain fabric is flexible and has appropriate tension and elasticity, and the curtain fabric is suitable for a roll curtain or the like. Therefore,
Even if the outer material 11 is not suitable for a roll curtain or the like because it does not have tension, it can be used as a curtain fabric 1 for a roll curtain or the like. At this time, the expansion and contraction of the curtain fabric 1 in the illustrated vertical direction is
Compared to expansion and contraction of the outer material 11 in the same direction, it will be much smaller,
It is suitable to use this direction as a pulling direction for a roll curtain or the like. Moreover, the curtain fabric 1 has an appropriate tension, regardless of the direction of the texture of the outer material 11. That is, since the cutting direction of the outer fabric 11 can be changed arbitrarily, the curtain fabric 1 having various patterns and patterns can be manufactured even if the same outer fabric 11 is used. In this manner, by bonding the interlining 12 to the non-tensioned outer fabric 11 or the bias-cut outer fabric 11, it is possible to use a curtain fabric that has been difficult to use as a roll curtain or the like in a roll curtain or the like. Therefore, it is possible to manufacture a roll curtain or the like having curtains of various characteristics and patterns. Furthermore, the degree of tension of the curtain fabric 1 can be adjusted by appropriately selecting the materials, types, thicknesses, etc. of the outer fabric 11 and the interlining 12, so that the curtain fabric 1 having tension and stiffness according to various applications can be simplified. It will be possible to manufacture.

Further, since the surface material 11 is not coated with a resin or a transparent film as in the prior art, the original characteristics of the material 11 are not impaired at all.
Rather, decorativeness is greatly enhanced by the feeling of tightness. Furthermore, since the outer fabric 11 and the interlining 12 are easily and firmly adhered to each other with the adhesive 13 having a heat-sealing property, the curtain fabric 1 having sufficient elasticity can be easily obtained. Further, since the adhesive 13 does not exhibit tackiness and adhesiveness unless heat is applied, handling of the interlining 12 having the adhesive 13 attached thereto is very easy. Since the strong bonding as described above can be achieved only by superposing the outer fabric 11 and the interlining 12 and applying heat, the curtain fabric 1 is extremely easily manufactured.

Further, since the production is simple as described above, there is an advantage that the curtain fabric 1 can be produced in a lot unit smaller than the conventional dyeing lot, and further can be produced from the end cloth. With such an advantage, for example, an end cloth of a curtain (which has no tension) and which is rich in flexibility and has an elegant texture used for a large sash window of a room is used as the outer material 11.
The curtain fabric 1 is manufactured by using
Therefore, total coordination such as manufacturing roll curtains for small windows and other cloths can be performed very easily.

Furthermore, since the side edges of the curtain fabric 1 are melted and welded, the threads on the side edges of the outer fabric 11 and the interlining 12 and the bonded outer fabric 11 and interlining 12 may be separated. Is prevented. In addition, in contrast to the side edges that have been traditionally sewn on three rolls or coated, the side edges do not become thicker than other areas, so the curtain fabric 1 should be used for roll curtains, shade curtains, etc. More suitable. Moreover, since the side edges of the curtain fabric 1 are decorated at the time of fusing and welding, the design and functionality of the side edges are extremely enhanced. Therefore, it is possible to obtain the curtain fabric 1 which is extremely excellent in design and function. Since the fusing and welding are performed by ultrasonic cutting, it is possible to obtain the curtain fabric 1 in which the side edges are uniformly treated and the finish is more beautiful.

FIG. 2 shows a second embodiment of the curtain fabric of the present invention.
It is an exploded perspective view showing an embodiment. The curtain fabric 2 shown in FIG. 2 is formed by laminating an outer fabric 21 made of a knitted fabric and an interlining 22 made of a resin film having thermoplasticity. An adhesive 13 is attached to the bonding surface of the interlining 22, and the outer fabric 21 and the interlining 22 are simply and firmly bonded by the adhesive 13 like the curtain fabric 1 shown in FIG. Has been done. Since the outer material 21 is a knitted material, it is generally highly stretchable and does not have a tension and elasticity, and is rarely used alone for a roll curtain or the like. On the other hand, the interlining 22 has a smaller expansion / contraction than the outer material 21, and does not have a particularly large expansion / contraction in a specific direction like a woven fabric. However, also in the curtain fabric 2 configured as described above by adopting the knitted fabric for the outer fabric 21, the same action and effect as the curtain fabric 1 shown in FIG. 1 are exhibited.

FIG. 3 shows a third embodiment of the curtain fabric of the present invention.
It is an exploded perspective view showing an embodiment. The curtain fabric 5 shown in FIG. 3 is obtained by laminating an outer fabric 51a made of a woven fabric, a woven fabric 51b, and an interlining 52 made of an adhesive sheet 53 (heat-fusible material; so-called heat sheet) having heat-fusible property. Made up of. The outer material 51a and the woven fabric 51b have different pattern patterns, and both can be used as the surface pattern (front side) of the curtain. The adhesive sheet 53 is a non-woven fabric made of heat-fusible resin fiber. The outer fabric 51a and the woven fabric 51b are overlapped with each other so as to sandwich the adhesive sheet 53, and heat is applied to firmly bond the both. The curtain fabric 5 configured in this way has the same effect and effect as the curtain fabric 1 shown in FIG. 1, and has an advantage that both sides of the curtain fabric 5 can be used as a front pattern (front side). . Therefore, by using the curtain fabric 5 as a roll curtain or the like, it is possible to manufacture a roll curtain or the like that can be used as a surface pattern on both sides.

FIG. 4 is a perspective view showing a preferred embodiment of the roll curtain of the present invention. Roll curtain 3
The base end portion of the curtain 31 made of the curtain fabric of the present invention is the winding direction of the curtain 31 (A shown in FIG. 4).
Direction) and the delivery direction (the direction opposite to the A direction shown in FIG. 4). The winding shaft 32 has bearing portions 3 at both ends.
It is rotatably supported by 3, 34, and its upper half is surrounded by a cover case 38. Further, a shaft (not shown) is inserted inside the winding shaft 32, and a torsion spring (not shown) for urging the winding shaft 32 in the winding direction of the curtain 31 is arranged with respect to this shaft. It is set up. Thus, the winding means is formed by the winding shaft 32, the shaft, and the torsion spring. A cam ratchet (not shown) connected to the shaft in the winding shaft 32 is provided inside the bearing portion 33, and the rotation of the shaft is locked by the cam ratchet ( It is fixed) and this lock is released. Further, an operation string 37 for operating the curtain 31 is connected to the front end portion (lower end portion in the drawing) of the curtain 31 via an annular ring 36, and a weight core material 35 for keeping the tension of the curtain 31 is provided. It is attached along the leading edge of the curtain 31. As the internal structure of the take-up shaft 32 and the structure of the cam / ratchet etc., it is possible to use the well-known structures listed or cited in, for example, JP-A-9-278295.

According to the roll curtain 3 thus constructed, the curtain 31 is made of the curtain cloth of the present invention having flexibility and moderate tension, and therefore, the curtain 31.
When the curtain 31 is pulled out from the cover case 38 and the operation string 37 is operated to wind the curtain 31 around the take-up shaft 32, it is possible to prevent twisting or disturbance. Therefore, the curtain 31 is wound up neatly and smoothly by the winding shaft 32. Further, since the curtain 31 can be manufactured from a curtain cloth having a surface material which has been difficult to use as a roll curtain in the related art, it is possible to manufacture the roll curtain 3 having the curtain 31 having various characteristics and pattern patterns. Become. Therefore, it is possible to significantly expand the types of products (product width) of the roll curtain 3. In addition, since the curtain 31 has an enhanced decorative property due to the feeling of tightness, the decorative property of the roll curtain 3 is also enhanced,
A sense of quality can be imparted to the roll curtain 3.

FIG. 5 is a perspective view showing a first embodiment of the shade curtain according to the present invention, showing a state in which the curtain, which is a constituent member, is pulled down, and FIG.
FIG. 4 is a perspective view showing a state in which the curtain is rolled up.
The shade curtain 4 shown in FIGS. 5 and 6 is formed by fixing the base end portion of a curtain 41 made of the curtain fabric of the present invention to a support case 42 (support). Further, one end of an elevating cord 44 (a linear member) is connected to the tip end portion of the curtain 41, and the elevating cord 44 has a plurality of annular rings 43 attached to the core ground of the curtain 41 at predetermined intervals. The (restriction means) communicates vertically. The lifting cord 44 is slidably supported by the guides 46 and 47 inside the support case 42,
The other end of the elevating cord 44 is pulled out downward through a hole formed in the bottom wall of the end of the support case 42. In this way, the lifting cord 44, the annular ring 43, and the guide 4
Elevating means are formed by 6, 47.

The guide 47 is a gear-type lock mechanism that locks (fixes) the lifting cord 44 at a desired position and can release the lock.
Further, a weight core material 45 for maintaining the tension of the curtain 41 is attached along the leading edge of the curtain 41. From the state shown in FIG. 5, when the elevating cord 44 on the side of the curtain 41 is pulled downward, the elevating cord 44 in the portion communicating with the annular ring 43 is pulled up, and the curtain 41 is rolled up. It becomes the state shown.

The shade curtain 4 constructed in this way
According to the method, since the curtain 41 is made of the curtain fabric of the present invention having flexibility and moderate tension, the curtain 4
The folded folds generated when rolling up 1 are not disturbed or caught (see FIG. 6). Therefore, the curtain 41 can be raised and lowered cleanly and smoothly without using the conventional rod-shaped member. Further, since the conventional rod-shaped member is not required, the curtain 41 can be folded compactly as shown in FIG. 6, and the appearance of the shade curtain 4 can be neatly improved by improving the aesthetic appearance of the shade curtain 4. It is possible to Further, since the conventional rod-shaped member and the bag portion or member for attaching the rod-shaped member are unnecessary, the number of parts is reduced. Therefore, the cost can be reduced. In addition, since it is not necessary to sew the bag portion or attach the rod-shaped member, the number of manufacturing steps can be reduced. Therefore, the cost can be further reduced. In addition, since there is no bar-shaped member and the above-mentioned sewn portion, the shadow of the bar-shaped member and the seam is not projected on the front side of the curtain 41. Therefore, the aesthetic appearance of the shade curtain 4 can be further improved. Further, since there is no sewn portion as described above, there is no risk of light leakage as in the conventional case. Therefore, for example, by using a material having a light blocking property as the interlining material of the curtain 41, it is possible to obtain the shade curtain 4 having a good light blocking performance. Also,
Since the side edges of the curtain 41 are fused and welded,
In contrast to conventional three-roll sewing and coating treatment, it does not become thicker than other parts. Therefore, the resistance when the curtain 41 is rolled up can be reduced. In addition to that, since the rod-shaped member is unnecessary and the weight of the curtain 41 is reduced as a whole, the operability when the curtain 41 is moved up and down can be remarkably enhanced.

FIG. 7 is a perspective view showing a second embodiment of the shade curtain according to the present invention. The shade curtain 4 shown in FIG. 7 has the same configuration as that of the shade curtain 4 shown in FIGS. 5 and 6 except that the annular rings 43 have different vertical and horizontal intervals. As described above, in the conventional shade curtain, the rod-shaped member is used to prevent the folded folds from hanging down. In such a conventional shade curtain, when the annular ring is attached to the curtain, if the interval between the annular rings is excessively widened, the curtain does not have tension and the annular ring becomes the apex and the curtain becomes unnecessarily large. It tended to hang and was not beautiful. Further, when the rod-shaped member is removed from the conventional shade curtain, this tendency naturally becomes remarkable, and such drooping can be prevented only by the multipoint support using many annular rings, lifting cords and guides. On the other hand, according to the shade curtain 4 of the present invention, since the curtain 41 has a reasonably sufficient tension, even if the distances d1, d2, d3 and d4 shown in FIG. Is prevented from hanging down more than necessary. Therefore, the appearance of the shade curtain 4 can be improved and the annular ring 4
3, it is possible to further reduce the cost by reducing the number of parts of the lifting cord 44 and the guide 46.

Specific material raw materials for the outer material and interlining material constituting the above-mentioned curtain fabrics 1, 2, 5 are, for example, cellulose, polyester, nylon, polyethylene, polypropylene, polyvinyl chloride, vinylon, polypropylene, Examples of the material include polystyrene, acrylic, metal and the like. Further, from the viewpoint of the processability of the side edge of the curtain fabric and the bondability when the outer fabric and the inner fabric are laminated, it is preferable that at least one of the outer fabric and the inner fabric has thermoplasticity. Also, curtain fabrics 1, 2,
Although the outer surface of 5 is composed of one layer, it may be composed of a plurality of layers. This makes it possible to obtain a curtain fabric having a more varied pattern pattern due to the overlapping of patterns, especially when the surface fabric is thin. Therefore, by using such a curtain fabric, it is possible to further expand the types of products such as roll curtains and shade curtains. Further, the outer material may be embroidered, piled, flocked, napped, etc., and the types of products can be further expanded.

In each of the above-described curtain fabrics 1 and 2, the adhesive 13 is attached to the interlinings 12 and 22, but the adhesive 13 may be attached to the outer fabrics 11 and 21. Needless to say, the adhesive 13 may be attached to the bonding surfaces of both the outer materials 11 and 21 and the interlining materials 12 and 22. Further, the adhesive is not limited to the adhesive 13 (hot melt) and the adhesive sheet 53 (heat sheet), and if the adhesive has thermal adhesiveness, an adhesive composed of another thermal adhesive material. It may be an agent. As the main component of the adhesive, a synthetic organic compound such as vinyl acetate, polyvinyl alcohol,
Polyvinyl acetal type, vinyl chloride type, acrylic type,
Examples include components containing polyamide-based, polyethylene-based, cellulose-based, urea-based, melamine-based, phenol-based, epoxy-based, polyester-based, polyurethane-based, polyaromatic-based, resorcinol-based compounds, etc., and these components may be used alone or in combination with 2 It is used as a mixture of two or more species. And if necessary, a solvent, a plasticizer, a resin, a filler, a pigment, a curing agent, a deterioration inhibitor, an antiseptic, a thickener, an antifoaming agent, a coupling agent (enhancing agent), etc. are added to these main components. It is preferable to add it to form an adhesive.

As described above, one feature of the curtain fabric of the present invention is that it is laminated with a heat-fusible material. The outer fabric and interlining are room temperature curing type, heat curing type,
It can also be stuck by other pressure-sensitive and rewet type adhesives. The adhesive does not have to be an attached solid, film or sheet, and may be in the form of a solution, emulsion, powder or the like. As the other adhesives, synthetic organic adhesives such as chloroprene-based adhesives, nitrile rubber-based adhesives, styrene rubber-based adhesives, butyl rubber-based adhesives, silicone rubber-based adhesives, and synthetic rubber-based adhesives containing compounds such as polysulfide-based adhesives, or natural adhesives. Examples include system adhesives and synthetic inorganic adhesives.

Furthermore, in each of the above embodiments of the curtain fabric, the side edges of the curtain fabric are fused and welded by ultrasonic cutting, but they may be fused and welded by heater cutting or laser cutting. Also,
In the roll curtain 3 described above, as a method of fixing the base end portion of the curtain 31 to the winding shaft 32, it may be bonded or may be easily fixed by a surface fastener or the like. Furthermore, in the shade curtain 4 described above, the curtain 4
The method of fixing 1 to the support case 42 is also the same.

[0032]

As described above, according to the present invention, it is possible to obtain a curtain fabric which is flexible and has a proper elasticity without deteriorating the original characteristics of the fabric of the curtain fabric. Further, it becomes possible to expand the variety of products by using curtain fabrics that have been difficult to use in the past, and to obtain a roll curtain capable of enhancing decorativeness. Furthermore, it is possible to obtain a shade curtain that can improve appearance and can reduce cost.
