Description

[0001] The present invention relates to a method for manufacturing a functional quilt and a quilt made therefrom,

The present invention relates to a method for manufacturing a functional quilt and a quilt made therefrom. More specifically, the quilt is prepared by inserting a general chemical cotton rather than a natural cotton such as goose down, using a dense fabric as a cover, The present invention relates to a method for manufacturing a functional duvet and a duvet made therefrom, in which the feeling of warmth and volume is excellent, the weight is light, the manufacturing cost is reduced, and the burden on the consumer is reduced.

Generally, bedding covers the user's body when sleeping and keeps the body temperature warm so as to provide a comfortable sleep. In order to maintain the warmth and provide the user with comfortable and comfortable sleeping, it is very important to select the cover as well as the cover .

The cover is made of quilted cover with quilted cover, quilted cover which is usually used as usual, and cotton in winter, quilted cover facing the upper and lower cover without quilting, Put thick cotton and quilted bed cover is divided into.

This is a cotton that is put in a futon cover. Such a cotton wool is made of a chemical cotton (artificial cotton) such as polyester cotton, polypropylene cotton, cotton wool, silk cotton, wool, goose hair, And the like, and it is possible to use the cover and the cigarette according to the season or the user's need.

For example, a conventional futon is made of a stitch to stitch by covering various fabrics such as 30 or 60 waterproof fabrics as a cover and a general chemical cotton such as polyester cotton as an inner layer.

That is, the rolls (rolled cotton) that have been subjected to the resin treatment and heat treatment on the surface are spread out, cut to fit the cover fabric size, and then put back between the upper and lower covers. Then, If you want to increase the warmth at this time, you can use thick rolls.

The fabric thus produced is inexpensive, has a good production yield, and is easy to clean because it has good recovery ability of laundry. Therefore, although it is widely used among general consumers, the volume of the chemical cotton used as a chewing gum is not good, Not only the feeling of softness disappears but also the thicker rolls must be used in order to use it more warmly, so that it is heavy and costly, and the air permeability of the cover fabric is high.

Further, as shown in FIG. 6, the conventional duvets have a limited thickness and a limited restoring force as they are sewed in a direct sewing method in which the rolls 400 are inserted into the inside and the upper and lower covers 100 and 200 are directly sewn against each other .

Conventionally, natural cotton such as goose down or duck down may be put in order to increase the resilience and warmth of the futon. In order to prevent the feathers from escaping to the outside, the cover fabric is down- It is processed and processed so that the hairs can not come out by narrowing the holes by closely contacting the fabric with strong heat.

The futon thus produced has a volume feeling, a light weight, a light weight, a good air permeability, a unique resilience of the goose down fur, a good resilience, a warmth and warmth, a difficulty in processing, And the restoration power and warmth are lowered as time goes by, and the hairs come out through the cover fabrics to stimulate the skin, or the volume feeling may be considerably reduced to shorten the life span.

Moreover, these futons do not allow the air to flow well, causing the goose hair to shrink or get wet, occasionally to smell hair, and to worry about corruption.

Disclosure of Invention Technical Problem [8] Accordingly, the present invention has been made to solve the above-mentioned problems, and it is an object of the present invention to provide a method for producing a functional duvet which is lightweight, excellent in warmth and volume feeling and inexpensive price by improving disadvantages of ordinary chemical duvets and goose down duvets, have.

In order to achieve the above object, the present invention provides a method of manufacturing a futon which is used as a cover of a futon using a dense fabric mainly used for industrial safety protective clothing, winter jumper, automobile cover, etc., And a space portion is formed to fill various spaces such as a chemical cotton such as a polyester cotton in each space portion.

That is, according to the present invention, there is provided a method for manufacturing a futon comprising filling a space between an upper cover and a lower cover, wherein a strip-shaped spacing member is arranged between the upper cover and the lower cover in a lattice- Forming a slit by cutting at least one of a transverse direction and a transverse direction at each intersection of the spacing members arranged in the transverse direction and the transverse direction; Sewing the four edges of the upper and lower covers and opening a part thereof to form an injection port; Filling each of the spaces with a common chemical swab through the injection port and the slit; And sewing and finishing the injection port so that the injection port is closed, wherein the upper and lower covers use a dense fabric that does not allow air to pass therethrough.

Here, the upper cover and the lower cover use high-density polyethylene fibers, and the diameter of the microfibers constituting the warp yarns of the polyethylene fibers is preferably 0.5 to 10 mu m.

The upper cover and the lower cover may have a pore size of 0.1 to 10 mu m between the fibers (warp yarns).

In addition, the upper cover and the lower cover may be formed by padding a padding pad on each inner side surface, and the upper cover and the lower cover may have a surface cloth And sewing together the pads.

In addition, the spacing member is a strip-shaped tape fabric.

According to the method for manufacturing the functional quilt of the present invention and the quilt formed therefrom, the quilt is manufactured using the high-density fabric used mainly for the winter jumper and the garment, and the quilt is sewn by the three-dimensional sewing method, (Goose Down) It complements the disadvantages of the futon, and it has better warmth and volume feeling compared to goose down duvet while applying general chemical cotton, and it is not only good in texture but also light in weight. And the cost is much lower than that of the conventional goose down comforter, which is a very economical effect that can satisfy consumers' purchasing desires.

In addition, it is possible to use all kinds of cotton including general chemical cotton, and it does not need to process the cotton itself like goose down duvet and does not come out of the cotton cover, so that it can be used while maintaining the volume feeling for a long time, Even if it is used, there is no problem such as smell or feather out, which is convenient for use.

Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings so that those skilled in the art can easily carry out the technical idea of the present invention.

FIG. 1 is a perspective view briefly showing a functional duvet according to a preferred embodiment of the present invention, and FIG. 2 is a partially exploded perspective view of FIG. 1.

Referring to the drawings, a functional quilt Q according to a preferred embodiment of the present invention includes a rectangular upper cover 10, a lower cover 20 of the same shape coupled to a lower end of the upper cover, Like spaced apart members (30) arranged in a lattice pattern at regular intervals therebetween such that the lower cover and the lower cover are separated by a predetermined height, and a plurality of space portions (40) embedded in the upper and lower covers (32), and the upper and lower covers (10, 20) are made of high density fabric.

According to another aspect of the present invention, there is provided a method for fabricating a functional quilt comprising the steps of: forming a plurality of spaced apart spacing members between upper and lower covers made of high-density raw fabric in a state of standing vertically in the transverse direction, Each space is filled with ordinary chemical cotton, such as polyester cotton, as a filling material.

This will be described in more detail as follows.

[1] Preparation of raw materials

As shown in FIG. 1, the upper cover 10 and the lower cover 20 constituting the futon are the most characteristic constituent elements of the present invention, and a high density fabric is used as a material. Particularly, the durability and the waterproofness are good It is most preferable to use a high-density polyethylene fiber composed of fine fibers having a diameter of 0.5 to 10 mu m.

At this time, the pores between the fibers constituting the fabric of the upper and lower covers 10 and 20 are preferably 0.1 to 10 mu m, so that only minute amounts of air permeate but not water So that fine particles such as mites can not pass through.

The upper and lower covers 10 and 20 may be formed by padding a padding pad (not shown) having a thickness of 0.3 to 10 mm on each inner surface as an inner skin to further increase the warmth.

The spacing members 30 are arranged in a lattice shape at regular intervals in the transverse and longitudinal directions so as to be spaced apart from each other by a predetermined height between the upper cover 10 and the lower cover 20, Or an elongated strip of tape-like material made of different materials can be used, and the tape is cut to have a width of about 3 to 5 cm.

As the inner tube 40, a common chemical cotton such as polyester cotton, polypropylene cotton, etc. is used, but not limited thereto, and all kinds of cotton can be used.

At this time, it is preferable to use a micro-foam (a type of cotton spreading like a cloud) so that a small amount of cotton can be inputted.

[2] Sewing (formation of space part)

Subsequently, a plurality of spacing members 30 are inserted between the upper and lower covers 10 and 20 and sewed, but the sewing is performed in a three-dimensional sewing method (Baffle Construction).

That is, a strip-shaped spacing member 30 is arranged between the upper cover 10 and the lower end of the lower cover 20 so as to be vertically arranged at regular intervals in the horizontal and vertical directions so as to form a lattice, And the inner side portions of the lower cover are sewn to the lower portions of the spacing members, respectively.

Alternatively, as shown in FIGS. 2 and 3, the separating members 30a and 30b may be joined to the upper cover 10 and the lower cover 20, respectively, and then the upper and lower covers may be sewn together to connect the upper and lower covers .

At this time, it is preferable that the spacing member maintains a gap of about 1 to 5 cm between the upper and lower covers spaced apart by the spacing members as they are sewn to the upper and lower covers while leaving the contact portion.

At least one of the longitudinal direction and the lateral direction of the spacing member is cut at a portion where the spacing member disposed in the transverse direction and the spacing member disposed in the longitudinal direction cross each other, Make sure that it does not hinder building.

Accordingly, when the upper and lower covers 10 and 20 are coupled to each other through the spacing member 30, the slit 31 is formed at the intersection of the longitudinally and laterally spaced apart members, .

Alternatively, in place of the cutting process, the length of the one-way spacing member may be trimmed in advance by shortening the spacing of the spacing members among the spacing members disposed in the lateral direction or the longitudinally spaced spacing members.

In addition, slits 31 'may be formed in all four directions as shown in FIG. 4 at the intersections of the lateral and longitudinal spacing members located close to the injection port, which will be described later, to facilitate injection of the fluid.

As described above, the spacing between the upper and lower ends of the upper and lower covers 10 and 20 is separated by a predetermined height by the plurality of spacing members 30 sewn in the transverse direction at regular intervals, and a plurality of space portions 32 are formed 5, in the present invention, when the foam is poured between the top cover and the bottom cover of the present invention in a later process, Not only the cotton is moved from one space portion 32a to the other space portion 32b by the spacing member but also there is no phenomenon that the cotton yarns are bundled together and are pushed in one direction of the futon,

Before sewing and joining the spacing member 30 between the upper cover 10 and the lower cover 20, previously cut surface fabrics (not shown) are stuck on the outer sides of the upper and lower covers, As described above, since the upper and lower covers 10 and 20 used in the present invention are made of a fabric that does not allow water to pass therethrough, the sweat absorbing power is increased by the outer surface fabric, To keep it.

Here, the outer surface of the upper and lower covers 10 and 20 may be replaced with other materials as long as they have the same functions as those described above.

After the coupling of the spacing member 30 is completed, the four edges of the upper and lower covers 10, 20 are sewed. At this time, a part of the four edges is opened by a predetermined length so as to fill the baffle in the subsequent process, 15).

[3] charge charge

Next, in order to fill the inner tube 40 between the upper and lower covers 10, 20 in which the plurality of space portions 32 are formed, the nozzle pipe M of the cotton injector is charged into the injection port 15 And passes through the slit 31 formed in each of the space parts to inject the cotton into each space part.

That is, in the process of injecting the cotton with the nozzle pipe M, air is injected together with the cotton, so that the space is expanded, and even if a small amount of cotton is injected, a rich volume feeling is produced by the air. 10, 20) are made of a high-density fabric having a low air permeability, the expansion of the air is more likely to occur.

[4] Finishing

Finally, after filling the inside of each space part 32 of the upper and lower covers, filling port 15 formed at the edge is sewn and finished.

In addition, when the spacing member 30 is sewn between the upper and lower covers 10 and 20 as described in the space forming step, it is also possible to combine the outer surfaces of the upper and lower covers with each other, However, such a cotton fabric may be covered by simply wrapping the outer side of the upper and lower covers in the finishing step. In this case, the cotton fabric may be dyed in various colors or may be used in various designs to give a visual design effect In such a case, it is also possible to extend the service life by reducing the wear of the upper and lower cover fabrics as a result of attaching a means such as a zipper to the outside of the outer surface fabric and peeling the surface fabric separately.

As described above, by the spacing member 30 arranged in a lattice shape inside the upper and lower covers, the cotton contained in one space portion is not moved to the other space portion but is put in place, Since it contains air with Madasom, it has a rich volume feeling by the air filled inside the space even though it contains a small amount of cotton, and its weight is not much, so it can be reduced by about 20% compared with the conventional duvet.

In addition, since the upper and lower covers 10 and 20 use a high-density fabric having a low air permeability and each space 32 serves as a bag for holding air, Not only does not go out well, but also keeps the futon in the cabinet, so that the inside air is taken out by pressing the futon in the folding process, and when the futon is unfolded for use again when necessary, the cotton is swollen and restored to the original state, The air is filled in between the cotton sheets to form an air layer, and the air thus introduced does not easily escape to the outside, but has a volume feeling.

In other words, since the volume feeling can be maintained for a long time without injecting the cotton such as goose hair or downy hair and the restoration power is improved, the stability of the futon having the roll cotton inside the cover made of the conventional cotton fabric is 20 to 30% The restorability of the bedding was as high as 80 ~ 90%. Also, when the bed was covered with the external cold air, the user 's body temperature was not taken out.

Further, as described above, since the fibers constituting the upper and lower covers 10 and 20 have pores such that the particles of a predetermined size or larger can not pass through, only the minute air passes and water can not pass therethrough. Mites could not enter the bed, and hygienic management of the bed was possible.
