DETAILED DESCRIPTION OF THE INVENTION

[0001]

TECHNICAL FIELD The present invention relates to a method for manufacturing a duvet. In particular, the present invention relates to a method of manufacturing a duvet having a crosslinked cloth for separating the inside of the duvet so that the filled down does not move, wherein the duvet is joined with an adhesive.

[0002]

2. Description of the Related Art Conventionally, in a duvet, the coupling and friction between the feathers are small, and the feathers filled in the duvet are easy to move in the duvet bag and are easily unevenly distributed. It is necessary to fractionate the interior of the futon into several small parts to prevent this. In addition, this separation cannot be prevented by merely stopping the futon cotton between the outer surface of the futon and the lining of the futon with a thread as in the case of ordinary futon cotton. Conventionally, a cross-linked cloth is provided between a futon outer material and a futon lining for the fractionation. In addition,
In the detailed description of the present invention, the duvet of the present invention will be described with the futon surface always located on the upper surface and the futon lining always located on the lower surface. Therefore, for example, the vertical plane is a plane perpendicular to the surface of the futon surface and the futon lining. The crosslinked fabric used for fractionation of this duvet was initially sewn to the surface of the futon and the lining of the futon with a thread, but the appearance of the thread on the surface of the futon was poor in appearance and disliked by consumers, and There is a defect that mites enter through the holes in the cloth and propagate, and that a fine piece of feather comes off from the holes in the yarn. In order to solve this drawback, a futon has been disclosed in which a crosslinked cloth is bonded to the upper and lower surfaces with an adhesive so that the thread does not appear on the surface of the futon fabric (Japanese Patent Application Laid-Open No. 62-87186). However, the structure of the crosslinked fabric by this method is shown in FIG.
Has a drawback that it is easily peeled off mechanically from the joining surface end m by the tension applied to the crosslinked cloth 1. Actually, the peeling force more than several times the tension applied to the cross-linked cloth is concentrated at the position of the joining surface end m in FIG. 8, so that the cross-linked cloth 1 is easily separated from the futon lining 8. Next, in order to improve this drawback, a cross-linked fabric disclosed in JP-A-5-42029 (Japanese Patent Publication No. 6-49015) has been proposed. As shown in FIG. 7A, the structure of the cross-linked cloth is such that the cross-linked cloth 1 is sewn to the center of the adhesive cloth n joined to the futon surface and the futon lining 8 by the adhesive layer 6 with the thread 5. Structure. That is, in this cross-linking structure, only another adhesive cloth n is temporarily attached with the adhesive layer 6 without directly attaching the cloth for cross-linking to the cloth complex, and the indirect cross-linking is performed at the center of the adhesive cloth n. The end of the cloth 1 is sewn. This is because, since the cross-linked cloth 1 is attached to the center of the adhesive cloth n, the tension applied to the cross-linked cloth 1 is evenly applied to both sides of the center mounting portion of the adhesive cloth n, so that the tension is not concentrated at one point, so that the bonding is performed. The cloth n is improved so as not to peel off. However, in the case of this crosslinked cloth, FIGS. 7 (a), (b), (c)
As can be seen from FIG.
The thread 5 is pulled in the vertical direction. Thus, when there is a tension applied perpendicularly to the thread, the thread is very likely to fray. This tendency is particularly remarkable when the thread is a chain stitch that is usually performed. The crosslinked cloth having the structure shown in FIG. 7 is strong at the beginning of use, but has a drawback that, during long-term use, for example, after about one year of use, the thread 5 is frayed and the crosslinked cloth 1 comes off the adhesive cloth n. As a result, a defect in which feathers are unevenly distributed appears. Further, in the case of the cross-linking cloth shown in FIG. 7, the thread 5 in which the cross-linking cloth 1 is attached to the adhesive cloth n is seen through the futon surface material or the futon lining, and has a disadvantage that the appearance is poor. That is, the crosslinked fabric of FIG. 7 in which the strength defect of FIG. 8 is improved is obtained by partially abandoning the original improvement of FIG. 7 of hiding the thread.

[0003]

SUMMARY OF THE INVENTION An object of the present invention is to produce a duvet which eliminates both the drawbacks of the conventional duvet in which threads are visible and the disadvantage that the crosslinked fabric comes off.

[0005]

BEST MODE FOR CARRYING OUT THE INVENTION The crosslinked cloth used in the production method of the present invention has two widths of 15 to 100 mm, preferably 20 to 60 mm.
When the width direction with respect to the longitudinal direction is kept vertical by polymerizing the cloth of 1 to 15 mm from the upper and lower edges, preferably 3 mm
A sewing structure on a joining line provided in the longitudinal direction along the upper and lower edges at an interval of ８8 mm or the inside of the joining line is fixed with an adhesive to form a central double cloth structure band. Then
A laminated fabric having a double fabric structure band at the center is cut to a desired length for use. The length of this cross-linked cloth is at least 30 mm
As described above, the length is preferably set to 50 to 2200 mm. Next, a cross-linked cloth having a horizontal glue surplus surface in which the pair of cloth edges above and below the joining line are opened in the left-right direction toward the cross section of the central double cloth structure band is formed. This is used in the method for producing a duvet of the present invention. The futon outer and lining cloths used in the present invention are JIS-L-10.
It is desirable to use a fine-grained material having an air permeability of 2.9 cc / cm ² / sec or less, preferably 2.7 cc / cm ² / sec or less according to the 96A method, from the viewpoint that fine feathers do not fall out and that ticks do not occur. In the production method of the present invention, the heat-sensitive adhesive sheets are temporarily attached to the upper and lower adhesive margins of the crosslinked cloth, respectively, and used. The heat-sensitive adhesive sheet used here is a resin sheet that is melted by heating. As the resin of the resin sheet, a resin having a melting point of 110 ° C. or higher, preferably 150 ° C. or higher is used. A hot melt of a low melting point resin is not preferable because the weld is loosened and removed when the duvet is heat-treated. The heat-sensitive adhesive sheet needs to be temporarily attached so as not to move between the futon surface and the lining before the thermocompression bonding. The method of temporary attachment is not particularly limited as long as it is held on the adhesive margin surface until the thermocompression bonding operation, and any method can be used. For example, a method in which a solution in which a heat-sensitive adhesive resin is dissolved is applied to a cloth on the surface of a paste and the solvent is dried, a method in which a heat-sensitive adhesive resin sheet is bonded with a pressure-sensitive adhesive, a cloth made of a heat-sensitive adhesive resin or a heat-sensitive adhesive A method in which a cloth impregnated with an adhesive is sewn or adhered to the adhesive margin can be used. In the production method of the present invention, the crosslinked cloth in a state where the central double cloth structure band is folded while maintaining the glue surplus surface of the crosslinked cloth horizontally open left and right is placed at a predetermined position between the futon surface and the futon lining. The thermosensitive adhesive sheet is melted by thermocompression bonding with a hot roll or a heating plate sequentially from both upper and lower surfaces on both sides simultaneously or on each side, and the heat sensitive adhesive sheet is used to form a futon outer material, a futon lining and the crosslinked cloth. The upper and lower glue surfaces are each welded and joined. This thermocompression operation, in a state where the cross-linked cloth formed as described above is sandwiched at a predetermined position between the futon surface material and the lining,
It can be carried out by passing between two heat rolls or by pressing with a hot plate simultaneously at the top and bottom or sequentially for each glue on the lower surface. Before or after the thermocompression bonding operation, it is necessary to join the periphery of the futon outer material and the futon lining leaving a filling port.
In this connection, it is desirable that the edges of the futon surface material and the lining are superimposed, and the superimposed edge is sewn by two or more rows of perforations having an average interval of 5 mm or less, preferably 3 mm or less. Such fine perforations in two or more rows at a narrow interval can increase the bonding strength of the periphery of the duvet and completely prevent the fine pieces of the feather from coming off the periphery. It also has the effect of preventing the infestation of mites. In the perforation of the present invention, since the outer material and the lining of the futon are firmly fixed, the inner feather does not directly contact the perforation.
In addition, at the time of joining the perimeter of the futon fabric, at least one of the periphery of the futon fabric or lining is folded back,
It is desirable to form the two rows of perforations on the folded edge. As a folded structure, as shown in FIG. 5 (a), which is an enlarged sectional view of the futon periphery, both peripheral edges are folded inward, and the two fabrics are folded inward to form a quadruple cloth structure formed by overlapping. A method in which the periphery is sewn by two rows of perforations R, or as shown in FIG. 5B, one is folded twice beyond the other periphery to form a perimeter of a quadruple fabric structure and two rows of perforations R Is desirably used. Lastly, after the feathers are evenly filled from the peripheral filling port to each of the fractions formed between the futon outer material and the lining, the filling port is joined in the same manner as the other peripheral edges, thereby providing the duvet of the present invention. Can be manufactured. Hereinafter, the present invention will be described in more detail with reference to the drawings. FIG. 1 is a basic perspective view showing the structure of the crosslinked cloth 1 of the present invention. In FIG. 1, two elongated rectangular cloths each having a width B and a length X are superimposed, and the width direction is maintained vertically as shown in FIG. Along this, two rectangular cloths are fixed by sewing with thread 5. When the width A portion is opened horizontally in the left-right direction with the double-sided opening, the cross-sectional structure shown in FIG. 2 is obtained.
This corresponds to a perspective view of the shape of the crosslinked fabric in the duvet of the present invention. The width B of this rectangular cloth is 15-100m
m, preferably 20 to 60 mm, and the length X is 30 mm
As described above, the width is preferably 50 to 2200 mm, and the width A of the paste margin is 1 to 15 mm, preferably 3 to 8 mm. Width B
Is appropriately determined by the thickness of the futon to be applied and the width A of the glue surrogate surface 3. When the width A of the glue margin surface is small, the adhesive strength is reduced,
If it is too wide, the feel of the duvet will be poor. The length X of the crosslinked cloth is 30 mm or more, preferably 50 to 2200 mm
The length is appropriately selected depending on the mode of fractionation of the futon.
In the center part of the crosslinked cloth 1 of FIG.
Adhesive glue surrogates 3 and 4 extending horizontally are formed on the upper and lower sides. As another embodiment of the present invention, as shown in FIG.
The same double cloth structure band formed by bonding the inside of the thread position of the book with an adhesive can be used instead of the crosslinked cloth of FIG. As the adhesive used in this case, a heat-sensitive adhesive, a pressure-sensitive adhesive or other known adhesives can be used. In particular, the adhesive is melted in the last thermocompression bonding step of joining the cross-linked cloth to the fabric. A thermosetting adhesive is desirable so that it does not come off. The crosslinked cloth of the present invention is obtained by applying a heat-sensitive adhesive to the upper and lower adhesive margin surfaces 3 and 4 and joining the upper and lower futon outer material and the inner surface of the futon lining with the adhesive to crosslink the crosslinked cloth to form a futon. The inside is fractionated with a cross-linked cloth.
FIG. 3 is a cross-sectional view showing a state in which the upper and lower futon linings and the futon lining are connected by a heat-sensitive adhesive. FIG. 3 shows FIG.
It is dd sectional drawing of (a). As shown in FIG. 3, the adhesive margin surface 3 and the futon surface material 7 are joined by welding via a heat-sensitive adhesive layer 6.

In this case, the tension applied to the upper and lower futon outer material and the futon lining is applied to the double cloth structure band 2 of the crosslinked cloth. This tension is applied to the upper and lower futon outer surface, the futon lining, and the bonding surface of the cross-over cloth 3 and the tension is uniformly applied to the left and right sides of the vertical cross section of the double cloth structure band 2. Therefore, the joining surface of the adhesive margin surface 3 does not peel off. Also,
In the prior art of FIG. 7, the tension applied to the cross-linked cloth is applied perpendicularly to the thread 5 sewing the cross-linked cloth and the bonding cloth before being applied to the joint surface between the adhesive cloth and the futon. For this reason, the thread 5 may be frayed and the crosslinked fabric may come off. On the other hand, the thread of the present invention sew two fabrics constituting the crosslinked fabric to form a double fabric structure band. There is no tension between the futon lining and the futon lining. In particular, there is no stress applied perpendicularly to the thread. Therefore, the thread of the present invention can be used in Japanese Patent Application Laid-Open No. 5-42029 (Japanese Patent Publication No. 6-4901), no matter how much tension is applied between the outer surface of the futon and the lining of the futon.
No. 5, No. 5) does not fray unlike the structure of the crosslinked fabric (FIG. 7). Further, since the thread is sewn with the double cloth structure band and does not face the futon surface and the futon lining, the defect that the thread can be seen from above the futon surface and the futon lining as shown in FIG. 7 is also improved. ing. It is apparent that the same effect as in FIG. 1 can be obtained when the cloth of the double cloth structure band portion, which is another embodiment of the present invention, is joined with an adhesive because no thread is present. As the position of the crosslinked fabric at the time of fractionation of the duvet of the present invention, the same position as the fractionation method performed with the conventional duvet can be appropriately adopted. For example, it can be fractionated at the position shown in FIG. 4 (a) or (b). In particular, the fractionation method of (b) is a method of performing the long fraction p and the short fraction r. In this method, the crosslinked cloth used in the present invention can be used on a parallel line over almost the entire length of the futon in a long fraction p that is shorter by about 2 to 10 cm than the length of one side of the duvet. It is efficient. By the cross-linked cloth set in the long fraction p, the duvet is fractionated into elongated sections by parallel lines at a constant interval of about 30 to 50 cm, and the interval between the parallel lines is shortened on the almost vertical short fraction r. By cross-linked cloth
As shown in FIG. 4B, the long fraction p can be separated so as not to intersect at intervals. It is necessary to leave a gap between the tip of the short fraction r and the long fraction p in FIG. 4 (b) in order to fill the entire area of the futon with feathers evenly.
The spacing can be 2-8 cm, preferably 3-5 cm. If the length is less than 2 cm, the operation of filling the feather becomes difficult. If the length is longer than 8 cm, the feather may move during use and may be unevenly distributed in the futon. For the purpose of this fractionation, the operation of joining the crosslinked fabric of the present invention between the outer surface of the futon and the lining of the futon can be performed, for example, by bonding the crosslinked fabric of the present invention to the glue surface 3 as shown in FIG. 6 (a) or (b). The heat-sensitive adhesive solution dissolved in the solvent is applied to the upper and lower glue sur- faces of the cross-linked cloth of the laminated structure formed by folding the double cloth structure band 2 between the upper and lower glue surplus surfaces while maintaining the open state. A heat-sensitive adhesive sheet temporarily attached with a pressure-sensitive adhesive or the like is placed at a predetermined position between the futon lining and the futon lining, and heated from outside the futon lining and the futon lining with a heating roller or a heating press. It is possible to complete the welding of the glue surface of the cross-linked cloth and the outer surface and lining of the futon with the heat-sensitive adhesive by pressing. As a method of temporarily attaching the heat-sensitive adhesive sheet to the paste surface, a method of gluing a heat-sensitive adhesive tape, a method in which a cloth in which the heat-sensitive adhesive is sufficiently impregnated is attached to the paste surface by sewing, or a thermoplastic resin yarn is used. Can be carried out by a method of attaching the woven or knitted fabric manufactured in the above to the glue surrogate surface by sewing. In the manufacturing method of the present invention, in order to avoid a problem that the crosslinked cloth is easily moved before the thermocompression pressing even when the crosslinked cloth is arranged at a predetermined position between the futon outer fabric and the lining, the crosslinked fabric is crosslinked to either the outer fabric or the lining. It is preferable that the cloth is temporarily fixed with an adhesive or low-temperature heating, and then covered with the other futon cloth and subjected to hot pressing. As the folded shape of the crosslinked fabric in the hot press operation in the present invention, for example, the shape shown in FIG. 6 can be considered. FIG. 6A shows a shape in which the center of the double cloth structure band 2 is expanded right and left and folded when the portion of the double cloth structure band 2 is formed by sewing. FIG. 6B shows a shape in which the double cloth structure band 2 is folded into a lightning bolt, and can be applied to a case where the double cloth structure band 2 is formed with a thread or an adhesive. Further, in any of the double cloth structure bands, thermocompression bonding can be performed in a state where the double cloth structure band is stretched to the shape shown in FIG. In this case, adjust the position of the futon outer material and the futon lining to the position shifted in advance by the length of the double cloth structure band to prevent the futon outer material and the futon lining from shifting and prevent the cross-linked cloth of the duvet from tilting can do. However, in the production method of the present invention, even if the crosslinked cloth of the duvet of the product is slightly inclined, the effect of fractionation and the performance of the futon are hardly affected. In the production method of the present invention, since the adhesive is a heat-sensitive adhesive during the operation of forming a crosslinked structure for fractionation inside the futon, when the operation of performing the alignment of the fractionation is performed at room temperature, the adhesive becomes Since it does not stick to the wrong position of the outer material or the futon lining, it can be adhered to the correct position between the glue surrogate surface 3 and the futon outer material 7 or the glue surrogate surface 4 and the futon lining 8. The heat-sensitive adhesive used in the present invention is, for example, a layer of a thermoplastic resin that is melted by heat, a thermosetting resin that is hardened by heat, or the like, or a resin tape is stuck on the paste margin surface and thermocompressed. Can be used without any particular limitation as long as it is possible. Preferably, it is desirable to use a layer of polyester resin, nylon, or polyurethane resin, or a tape of these resins, or a cloth tape in which these are impregnated into a cloth. In this way, the duvet of the present invention can be manufactured by uniformly filling each of the divided portions inside the futon with the crosslinked cloth between the futon surface and the futon lining with the down.

[0007]

The duvet manufactured by the manufacturing method of the present invention has a double cloth structure band at the center on the structure of the crosslinked cloth, and the double cloth structure band is provided at both end edges with respect to the double cloth structure band surface. There is an open glue surrogate surface, and the adhesive on the glue surrogate surface forms an adhesive portion that applies a uniform force to the cross-linked cloth in the left and right directions, so that the adhesive portion is strong. Furthermore, since the duvet manufactured by the manufacturing method of the present invention has no thread for fixing the cross-linked cloth and the adhesive glue surrogate, there is no disadvantage that the thread is unraveled by the tension applied to the thread and the cross-linked cloth comes off. Further, since the heat-sensitive adhesive is used, the manufacturing process of attaching the crosslinked cloth to the futon is easy. Further, the duvet manufactured by the manufacturing method of the present invention also has an improved defect that the thread can be seen through the futon surface or the futon lining. Further, by joining the periphery of the futon with two or more rows of narrowly-spaced perforations, there is an effect that falling off of fine feathers and entry of mites can be prevented. The present invention provides a method for producing a duvet having a particularly remarkable effect, and is industrially useful.
