Description

Down pack, Down Product Using the Same, and Manufacturing Method

The present invention relates to a product using a down, and more particularly, to a down pocket capable of stably filling down in a down charging part of a garment or bedding, a down product using the same and a manufacturing method thereof.

Down, which is a duck or goose's hair, is widely used for clothing and bedding because of its excellent heat retention and lightness. Down is a mix of feathers and feathers from the neck or chest of a duck or goose. Generally, the ratio of hair to feather is 4: 1 or 9: 1, and the higher the ratio of hair is, the lighter and warmer, the more hair is used.

The down product has a structure in which down is filled in the down charging part. Unlike cotton, it is not agglomerated and each one is independent, so if you use the product for a long time, the down will be thrown to one side. In order to solve such a problem, the down product is divided into a plurality of down charging parts which can be charged down by sewing.

If the down is placed first and then the sewing for partitioning the down charging part, the sewing line is not firm because the down is sewn together in the process of sewing. That is, since it is impossible to securely sew down charging portion, the down can often escape between the seams.

Therefore, in the related art, the down charging part is first formed by sewing, and then the down charging part is charged to the down charging part of the down product by blowing down the down charging part using a down injection tool. However, such a method may cause a problem that the down is buried around the opening of the down charging part, or the injected down comes out of the down charging part in the process of charging the down. That is, this problem occurs because the down is light and has the property of easily remaining on the outer surface of the down charging part by static electricity.

As such, the conventional method of directly filling down the down charging part has a problem that the down remains on the outer surface of the down product, is discharged to the work site without being charged to the down charging part, or falls off from the down product. Blown into the field, polluting the job site and making it impossible to maintain a clean work environment.

Moreover, since the down remaining on the outer side of the down product deteriorates the merchandise of the product, the process of shaking off the remaining down on the outer side of the down product generally needs to be performed separately before the down product is packaged and shipped. However, this lowers the production rate of down products and increases the manufacturing cost of down products.

Therefore, the present invention has been made in view of the above-mentioned conventional problems and needs, and an object of the present invention is to solve the problem that the down is applied to the outer surface of the down product in the process of filling the down product.

In this specification, down products are used generically to mean all types of products in which down can be used, such as clothing (down jumpers, vests, etc.), bedding (quilts, sleeping bags, pillows, etc.), sofas, handbags, and the like.

First embodiment

The down pouch 60 for down products according to the first embodiment of the present invention, as shown in Figure 1, comprises a down 64 and the bag body 62. The pocket body 62 has at least a portion of the rim 61 sealed with a heat sensitive sewing thread and has an inner space 68 in which the down 64 can be filled.

Thermo-sensitive sewing thread has a melting point at a lower temperature than a normal sewing thread, and melts away when heat is applied. That is, the thermally sensitive sewing thread has a low melting point of 50 ° C. to 90 ° C. that can be melted even when a temperature lower than steam heat when ironing, for example, 100 ° C. or less is applied. Heat-sensitive sewing thread can be used as the bundansa (separation yarn), also called, for example, Switzerland's EMS-GRILTECH GRILON ^ㄾ or Belgium LUXILON's single yarn (monofilament) products. However, this is only an example for the practice of the present invention, the present invention is not limited thereto. Any sewing thread having a melting point lower than heat during ironing can be used as the heat sensitive sewing thread of the present invention.

The thermally sensitive sewing thread may seal one edge, both edges, or the entire edge of the bag body 62. If heat is applied in the later ironing process, the edge portion 61 sewn into the heat-sensitive sewing thread bursts while the down 64 filled in the inner space 68 of the bag body 62 is discharged to the outside. In other words, if the iron is inserted after the down bag 60 is inserted into the down charging part of the down product, the heat-sensitive sewing thread melts and the down bag 60 bursts and the down 64 charged therein is discharged to open the inside of the down charge part. Will be charged. This will be explained later.

The material of the bag body 62 may be blown by a predetermined pressure, and there may be a small amount of foreign matter even if it remains in the down filling part, and an insoluble material that does not dissolve or loosen in water may be used, or a water-soluble material that dissolves in water may be used. For example, a plastic material, a nonwoven fabric, a thin fabric, or the like, which includes a thin and flexible vinyl, may be used as the insoluble material. In addition, functional materials such as ocher, jade, charcoal, elvan, amethyst and germanium may be added to the insoluble material.

As the water-soluble material, naturally degradable polyvinyl alcohol may be used. At this time, the reason why the water-soluble material is used as the material of the bag body 62, after inserting the down bag 60 in the down charging part of the down product and popped down to charge the down 64 to the down charging part, it remains in the down charging part. This is to remove the popped pocket body 62 from the down charging part easily through water washing.

On the other hand, the bag body 62 according to the first embodiment has been disclosed an example having a rectangular plate shape, but is not limited thereto. For example, the bag body 62 may have various shapes such as a polygonal plate, a disc, and a cylindrical shape.

When the down 64 is filled in the bag body 62, the bag body 62 is convex by the down 64. It is preferable to manufacture the down bag 60 smaller than the down packing part so that the down bag 60 can be stably inserted into the down packing part. It is preferable to pack the down 64 as densely as possible in the bag body 62 so that the down charging part can be filled with the down 64 filled in the small down pocket 60 as compared to the down charging part.

The down bag 60 according to the first embodiment may be manufactured separately, or a plurality of the down bags 60 may be manufactured in a batch. In the case of separately manufacturing the down bag 60, in the state in which the bag body 62 having the inlet is formed on one side, the down bag 60 is sealed by sealing the inlet with a heat-sensitive sewing thread after filling the down 64 with the inlet. ) Can be prepared. On the other hand, if some of the edge 61 of the bag body 62 is already sealed with a heat-sensitive sewing thread, the heat-sensitive sewing thread is not necessarily required to seal the inlet, and other types of sewing threads or other types of sewing methods may be used.

Hereinafter, a method of manufacturing a plurality of batches will be described with reference to FIGS. 1 to 5. 2 to 5 are views showing each process according to the manufacturing method of the down pocket 60 of FIG.

First, as shown in FIG. 2, a bag body 62 having an injection hole 68a formed on one side is prepared. The pocket body 62 used at this time has a size that can form a plurality of down pockets.

Next, as shown in FIGS. 2 and 3, the discharge portion of the down injection tool 67 is inserted into the injection hole 68a of the bag body 62 and down 64 into the inner space 68 of the bag body 62. Inject).

Next, as shown in FIG. 4, when the filling of the down 64 is completed, the injection hole (68a of FIG. 3) is sealed. In addition, the bag body 62 is sewn between the bag body 62 according to the number of divisions. At this time, the sewing line 65 formed on the inside of the bag body 62 is formed in a double at a predetermined interval. Reference numeral 63 denotes a sewing line 63 formed at the injection hole (68a in FIG. 3). The sewing lines 63 and 65 may be sewn with the above-described heat sensitive sewing thread, and if some of the edges 61 of the pouch body 62 are already sewn with the heat sensitive sewing thread, other types of sewing thread or other types of sewing methods may be used. May be used.

As shown in FIG. 5, the area between the sewing lines 65 inside the bag body 62 is cut with a cutter 69 such as scissors or a knife, so that the bag body 62 filled with the down is individually down-baged. Can be separated by 60.

In this case, the individual down bags 60 may be manufactured in the same size in a batch, or may be manufactured to have different sizes. The size adjustment of the individual down pockets 60 may be determined by the spacing between the seams 63, 65 (d1, d2, d3, d4 in FIG. 4). For example, as illustrated in FIG. 7, a plurality of down bags 60 are collectively formed to correspond to the plurality of divided down charging parts 40, respectively. In addition, when the down bag 60 is separated and charged in the down charging part 40 to correspond to each of the down charging parts 40, the manufacturing time of the down jumper 100 may be shortened.

On the other hand, the method of manufacturing a plurality of down bags 60 in a batch has been described an example of manufacturing the down bags in a row, but is not limited thereto. For example, m ㅧ n (m, n is a natural number of two or more) down pockets may be manufactured by sewing down in a lattice form after filling down through the inlet of the bag body.

Also, as shown in FIGS. 2 and 3, an example of injecting the down 64 into the bag body 62 through the injection hole 68a formed at one side of the bag body 62 is disclosed, but is not limited thereto. It is not. For example, as shown in FIG. 6, after the plurality of inlets 68a are formed in the bag body 62 through sewing, the down 62 may be injected through the plurality of inlets 68a.

Referring to FIG. 6, a plurality of injection holes 68a are formed at the long sides of the bag body 62. The size adjustment of the individual down pockets can be determined by the intervals d1, d2, d3, d4 between the seams 65. Then, after the down is injected, the plurality of down pockets as shown in FIG. 4 may be collectively manufactured by sewing the injection holes 68a collectively.

An example of a down product using the down bag 60 according to the first embodiment will be described with reference to FIGS. 7 and 11 as follows. The down product according to an example is a down jumper 100, which includes an outer shell 10, an inner shell 20, and a down 64.

The outer shell 10 and the inner shell 20 form a front plate 51, a back plate 53, and a sleeve 55 by sewing. The front plate 51 is divided into two parts so that the user can wear or remove the down jumper 100, and a fastener such as a button or a zipper is installed at the divided part. The inner shell 20 is located inside the outer shell 10 and forms a plurality of down filling parts 40 divided by sewing with the outer shell 10. The outer shell 10 and the inner shell 20 may be formed of one layer or a plurality of layers, and the outer shell 10 and the inner shell 20 located inside are sewn to form a plurality of down filling parts 40. At this time, the outer shell 10 exposed to the external environment may be a cloth woven with fibers having a cold protection and waterproof function.

The down 64 may be charged by inserting at least one down pocket 60 into the down charging unit 40 and then popping it. Alternatively, the down filling unit 40 is sewn in a state in which at least one down pocket 60 is positioned between the inner shell 20 and the outer shell 10 where the down filling unit 40 is to be formed, and then the down filling unit 40 is formed. The down 64 may be charged in the down charging unit 40 by popping up.

Specifically, the manufacturing method 70 of the down jumper 100 using the down bag 60 according to the first embodiment will be described with reference to FIGS. 7 to 11. 8 is a flowchart illustrating a manufacturing method 70 of the down jumper 100 of FIG. 7. 9 to 11 are views illustrating a process of charging the down charging unit 40 to the down charging unit 40 using the down bag 60 in the manufacturing method 70 of FIG. 8.

First, as shown in FIG. 9, the outer shell 10 and the inner shell 20 are sewn to form a plurality of down filling parts 40 having an injection hole 41 at one side (S71). In this case, reference numeral 31 denotes a first sewing line around the injection hole 41.

Subsequently, at least one down bag 60 is inserted into the down charging part 40 through the injection hole 41 (S73). At this time, when there is a difference in the amount to charge the down 64 according to the size or position of the down charging unit 40, the down pocket 60 is filled with the appropriate down 64 may be used.

Next, as shown in FIG. 10, the injection port of the down charging unit 40 is sewn to seal the down charging unit 40 (S75). Reference numeral 33 denotes a second sewing line formed by sewing an injection hole. The down charging part 40 is sealed by the sewing line 30 including the first and second sewing lines 31 and 33.

Next, as shown in FIG. 11, the down bag 60 is opened through the ironing 90 over the down charging part 40, and the down charging part 40 is charged with the down 64 of the down bag 60 (S77). ). That is, when the down product is ironed before shipment after manufacturing the down product, the down bag 60 bursts while the heat sensitive sewing thread sealing the edge 61 of the down bag 60 is melted by the steam heat of ironing. As the down 64 charged therein is discharged, the inside of the down charging unit 40 is charged.

And when the bag body 62 is made of a material that is soluble in water, the popped bag body 62 remaining in the down charging unit 40 can be removed by melting in the down charging unit 40 (S79).

Meanwhile, the down jumper 100 is generally packaged and shipped after completing the S77 process, and the S79 process may be performed by the purchaser who purchased the down jumper 100. Of course, it can also be performed by the manufacturer until the S79 process.

In addition, an example in which the bag body 62 is melted and removed from the down charging unit 40 in step S79 is disclosed, but is not limited thereto. For example, when the bag body 62 is a material that is dissolved in water, the popped bag body 62 remaining in the down charging part 40 may be dissolved by washing with water. In this case, even if the bag body 62 remains in the down charging part 40, the foreign body feeling can be further lowered.

Although the down jumper 100 is illustrated as an example of the down product using the down bag 60 according to the first embodiment, the present invention is not limited thereto. For example, as shown in FIG. 12, the present invention may also be applied to the manufacture of the down duvet 200. The down duvet 100 includes a sheath 110, an endothelial 120, and a down 64. At least one down bag 60 is disposed in the plurality of down charging parts 140 formed by sewing the outer shell 110 and the inner shell 120, and then the down 64 is charged to fill. Reference numeral 130 denotes a sewing line forming the down charging unit 140.

In this case, the down duvet 200 has a rectangular shape, but the example has been described in which the down charging unit 140 of the lattice form by sewing, but is not limited to this, a plurality of down charging unit 140 is formed in various shapes by sewing. Can be.

Specifically, the manufacturing method 80 of the down duvet 200 using the down bag 60 according to the first embodiment will be described with reference to FIGS. 12 and 13 as follows. FIG. 13 is a flowchart illustrating a method 80 for manufacturing the down duvet 200 of FIG. 12.

First, at least one down pocket 60 is placed on the endothelial 120 in a step S81 at the position where the down charging unit 140 is to be formed. In the present exemplary embodiment, an example in which the down bag 60 is disposed on the endothelium 120 is disclosed. However, the down bag 60 may be disposed on the outer bag 110.

Next, covering the outer shell 110 on the endothelium 120 in step S83, and sewing the endothelium 120 and the outer shell 110 to form a plurality of down charging section 140. Therefore, the down pocket 60 disposed on the endothelium 120 is positioned inside the down charging unit 140 formed by sewing.

Next, in step S85, the down pocket 60 is opened by ironing on the down charging unit 140 and the down charging unit 140 is charged into the down 64 of the down pocket 60. That is, when the down product is ironed before shipment after manufacturing the down product, the down bag 60 bursts while the heat sensitive sewing thread sealing the edge 61 of the down bag 60 is melted by the steam heat of ironing. As the down 64 charged therein is discharged, the inside of the down charging unit 140 is charged.

And when the bag body 62 is made of a material that is soluble in water, the popped bag body 62 remaining in the down charging unit 140 in the process S87 can be removed from the down charging unit 140 by melting with water washing.

In this case, the down duvet 200 is generally packaged and shipped after completing the S85 process, and the S87 process may be performed by the purchaser who purchased the down duvet 200. Of course, it can also be performed by the manufacturer up to S87 process.

In addition, an example of melting the pocket body 62 and removing it from the down charging unit 140 in step S87 is not limited thereto. For example, when the bag body 62 is a material that is dissolved in water, the popped bag body 62 remaining in the down charging unit 140 may be dissolved by washing with water. In this case, even if the bag body 62 remains in the down charging unit 140, the foreign body feeling can be further lowered.

As described above, the present invention sutures at least a portion of the edge of the down bag filled with down using a heat-sensitive sewing thread, insert the down bag into the down charging portion of the down product, and then heat-sensitive sewing thread through conventional ironing Melt to charge the down into the down charging part in the down pocket. Therefore, in the process of charging the down, the down does not occur on the outer surface of the down product, as well as the down is evenly charged in the down charging part, the down charging part is not only tightly formed, but also the design of the down charging part in various forms It becomes possible.

14 and 15 show examples of down products according to the present invention in which the down charging unit is designed in various forms.

Second embodiment

However, the down pocket of the second embodiment is characterized in that the material for sealing at least a portion of the edge of the bag body (62 of FIG. 1) (61 of FIG. 1) is an adhesive rather than a heat-sensitive sewing thread. That is, although the adhesive force is maintained at room temperature, an adhesive that loses or decreases the adhesive strength by steam heat during normal ironing can be used in place of the heat-sensitive sewing thread. For example, a thermoplastic material, a starch material, or the like may be used as the heat sensitive adhesive.

Therefore, at least a part of the edge of the down-filled down pouch is sealed with a heat-sensitive adhesive, the down pouch is inserted into the down filling part of the down product, and then the normalized ironing reduces the adhesive force of the heat-sensitive adhesive. The inside down can be charged in the down charging part. That is, due to heat or steam acting in the ironing process, the adhesive force of the heat-sensitive adhesive is reduced, the down pocket is opened by the filling pressure of the down and the down is discharged to the outside to fill the down charging part.

Third embodiment

The down bag 60 for down products according to the third embodiment of the present invention has the same configuration as most of the down bags of the first embodiment described above, as shown in FIG. However, the down bag 60 of the third embodiment not only seals the edge 61 of the bag body 62 using a heat-sensitive sewing thread or adhesive, but also at least one unsealing line on the outer surface of the bag body 62. (66) is further formed.

Therefore, when the down bag 60 is expelled by steam heat through the conventional ironing, the bag body 62 may be expelled and the down 64 may be discharged from the opening line 66 which is subjected to the pressure by ironing.

Fourth embodiment

In the first embodiment, the case of the bag body of the down bag is made of one of an insoluble material or a water-soluble material, but is not limited thereto. For example, as shown in FIG. 17, the pocket bodies 262 and 362 of the down pockets 260 and 360 may have a mixture of insoluble material portions 262a and 362a and water-soluble material portions 262b and 362b. . In addition, functional materials such as ocher, jade, charcoal, elvan, amethyst and germanium may be added to the insoluble material portions 262a and 362a.

Meanwhile, as illustrated in FIG. 17A, the bag body 262 may have a shape in which the insoluble material portion 262a and the water-soluble material portion 262b are alternately formed in a band shape. Alternatively, as shown in FIG. 17B, the bag body 362 may have a shape in which the insoluble material portion 362a and the water-soluble material portion 362b are alternately uniformly arranged in a lattice form. In addition, the bag bodies 262 and 362 may be variously formed through various combinations of the insoluble material portions 262a and 362a and the water-soluble material portions 262b and 362b.
