Description

Method for manufacturing a bed comforters}

The present invention relates to a method for manufacturing a charyeo comforter, and relates to a method for manufacturing a charyeo comforter for producing a charyeo comforter with increased warmth and weight.

In general, a blanket maintains body temperature during sleep to help sleep. Therefore, it is better to mix cotton fibers with good heat retention and light weight. In addition, a blanket made of a material that absorbs and releases sweat well is advantageous for temperature control. Various types of duvet cotton, such as microfiber, wool, goose, and duck down, can be used for the inside of the duvet. In order to prevent cotton from being flocked to some areas inside the duvet, the duvet is quilted and sewn inside and out together so that the cotton does not get pushed between the fabric and the fabric. In this way, the quilted quilt is called a charyeo quilt.

Conventional charyeop comforters have a problem in that the design of the fabric is damaged because the fabric is crumpled along the quilting line.

In addition, in the process of quilting, the conventional charyeob blanket has an empty space generated therein, and there is a problem in that the heat retention is relatively poor.

Therefore, there is a need for a charyeop comforter in which this problem is improved.

Hereinafter, with reference to FIGS. 1 to 10, a method for manufacturing a bedding for charyeo according to an embodiment of the present invention will be described.

First, prior to explaining the manufacturing method of the charyeo comforter, the structure of the charyeo comforter 100 will be described.

The charyeop comforter 100 according to an embodiment of the present invention includes a first shell 110, a second shell 120, and a filler 130. In addition to this, the charyeop comforter 100 according to an embodiment of the present invention further includes a third shell 140.

The first shell 110 is formed in a plate shape extending along the first direction (L ₁ ) and the second direction (L ₂ ). The first shell 110 forms one side of the charyeop comforter 100. The first shell 110 is disposed on the outer surface of the base layer portion 111 for absorbing sweat of the user, the mesh portion 112 disposed on the inner surface of the base layer portion 111 and having a ventilation function, and the base layer portion 111 It includes a heating layer part 113 having a heating function.

The base layer unit 111 is woven by mixing any one or two or more selected from hydrophilic polyester yarn, polyamide yarn, cotton, and wool fiber to impart a moisture absorption function.

Furthermore, in order for the base layer part 111 to more quickly and smoothly absorb the sweat generated from the human skin located inside, the inner surface of the base layer part 111 is brushed in the form of scraping the surface like a rising method (111a). ) is preferably formed. Since the density of the napped hair 111a formed on the inner surface of the base layer portion 111 is relatively low, and the density is relatively high in areas where the nape 111a is not formed, moisture such as sweat in contact with the napped hair 111a causes a capillary phenomenon. is rapidly absorbed into the base layer portion 111 layer by

The heating layer part 113 injects high-concentration conductive heating particles into the center of the hollow fiber to convert light energy such as infrared rays, ultraviolet rays, and visible light into heat, and then heats the fibers themselves to dissipate heat. The particles may be, for example, boron nitride (BN), aluminum nitride (AIN) or alumina (Al ₂ O ₃ ).

The base layer portion 111 and the heating layer portion 113 may be made of double-weave fabric through a conventional weaving machine such as a circular knitting machine or a tri-cord machine. That is, when weaving a double-weave fabric, one or more selected from polyester yarn, polyamide yarn, cotton yarn, and wool fiber yarn is supplied to the base layer portion 111, and the heating layer portion 113 is filled with conductive heat generating particles injected. We supply ester yarn.

Here, if the density of the heating layer part 113 is weaved more densely than that of the base layer part 111, the moisture absorbed by the base layer part 111 is absorbed into the heating layer part 113 again by capillarity, and the heating layer part ( 113) is quickly evaporated and dried by heat generated by the heating layer unit 113 itself.

The mesh unit 112 is made of a mesh structure to have a ventilation function, and may be, for example, a spacer mesh fabric (DNB Spacer Fabric) made by weaving polyester yarns in a mesh form, which is a three-dimensional three-dimensional structure.

Since the net portion 112 has a relatively low density and is made of a mesh shape and has a plurality of ventilation spaces 112a, it can absorb sweat and improve ventilation through the ventilation spaces 112a.

The mesh portion 112 may be fixed to the inner surface of the base layer portion 111 by thermal fusion, and the mesh portion 112, the base layer portion 111, and the heating layer portion may be fixed through a conventional weaving machine such as a circular knitting machine or a tri-cord machine. (113) may be woven into a triple weave fabric.

On the other hand, as described above, when the napping 111a is formed on the inner surface of the base layer portion 111, a portion of the napping 111a is exposed to the ventilation space 112a of the mesh portion 112, so that the mesh portion 112 itself Unabsorbed sweat can be absorbed by the nap (111a).

For example, when the first outer shell 110 is manufactured using a triple weave fabric, the net portion 112 is in contact with the user's skin, and sweat generated from the skin is absorbed by the net portion 112 and the napping 111a, Moisture absorbed by the mesh portion 112 and napping 111a is transferred to the base layer portion 111, and the moisture transferred to the base layer portion 111 generates heat with a relatively higher density than that of the base layer portion 111 by capillary action. It is transferred to the layer portion 113. At this time, the heating layer part 113 heats up as sunlight is irradiated and quickly evaporates moisture into the air, and since air flows into the ventilation space 112a formed in the mesh part 112, the user always feels a dry touch ( or fit) can be maintained.

A plurality of through-holes 113b may be formed in the heating layer part 113 and irregularities 113a may be formed on the surface of the heating layer part 113 at the same time. When placed in a low-thickness part, the surface area of the heating layer part 113 in contact with the air further increases, and since a part of the surface of the base layer part 111 directly contacts the air, the moisture absorbed in the base layer part 111 is directly transferred to the atmosphere. This allows for evaporation to further increase the rate of evaporation of moisture.

If irregularities 113a are formed on the surface of the heating layer unit 113, a plurality of through holes 113b are formed in the heating layer unit 113, or the irregularities 113a and through holes 132 are formed at the same time, the first shell 110 Since the outer surface of ) has a predetermined pattern by the irregularities 113a and/or through holes 132, the appearance (surface) of the first shell 110 can be designed in various ways by forming the pattern arbitrarily. There is also

On the other hand, the first shell may be manufactured in a different configuration from the above-described method. Hereinafter, the first shell 110 manufactured in a configuration different from the above-described method is referred to as a first shell according to a modified example.

The first outer shell according to the modified example includes a main outer skin layer (not shown) and a fragrance generating layer (not shown).

The main outer skin layer is formed of an antibacterial fabric in which antibacterial capsules containing phytoncide are inserted in the pores of a microporous fabric having a plurality of pores with an average diameter of 0.05 μm or more to 5.0 μm or less obtained by weaving lyocell-based fibers and microfibers. .

Here, Lyocell fiber is a compound word of Loy (slag) and Cell (cellulose) in Greek, and means a new material fiber made of cellulose extracted from wood pulp. Lyocell fiber has a soft touch comparable to silk, superior hygroscopicity than cotton, and strong durability comparable to polyester. It is also classified as an environmentally friendly fiber because it has characteristics. The reason why lyocell-based fibers are applied in the present invention is that the nanofibril structure of lyocell-based fibers imparts a near-perfect moisture control function to enhance the comfort of antibacterial bedding. In addition, in the present invention, the lyocell-based fiber may be selected from one or more of the group including Tencel (Courtaulds), Newcell (Acordis), Lenzing Lyocell (Lenzing), and cocel (KIST: Korea Advanced Institute of Science and Technology), but Tencel is may be most desirable. However, it is not limited thereto.

The fragrance generating layer is filled inside the main outer skin layer. The fragrance generating layer is an antibacterial capsule containing phytoncide having an average size of 0.055 μm or more to 6.000 μm or less on the surface of a microporous fabric having a plurality of pores having an average diameter of 0.05 μm or more to 5.0 μm or less obtained by weaving lyocell-based fibers and microfibers. It is produced through the process of dispersing the powder and simultaneously suctioning it from the opposite bottom surface to insert the antibacterial capsule into the pores of the microporous fabric, and removing the non-inserted antibacterial capsule powder from the microporous fabric into which the antibacterial capsule is inserted. .

Here, the antibacterial fabric includes an acrylic resin layer in which antibacterial capsule powder is dispersed on its surface.

On the other hand, lyocell-based fibers are produced by twisting 10 to 30% of exothermic acrylic fibers.

Microporous fabrics have a weft density of 80-150 filaments per inch.

In addition, the antibacterial capsule containing phytoncide is grapefruit, neroli, lavender, lime, lemongrass, lemon balm, rose, rosemary, marjoram, mandarin, basil, verbena, bergamot, orange, eucalyptus, jasmine, cypress, geranium, It further includes one or more aromatic oils selected from the group consisting of chamomile, juniper berry, thyme, tea tree, stronella, cedar wood, cinnamon, sandalwood, ylang ylang, and bay.

Meanwhile, the first sheath 110 further includes a first fastening tape 114, a first elastic fabric 115, and a friction fabric 116.

A fastening zipper 145 to be described below may be fastened to the first fastening tape 114 .

The first stretchable fabric 115 may be a stretchable fabric.

In addition, the first stretchable fabric 115 may be provided with a mesh-shaped auxiliary endothelium (not shown) between the first outer shell 110 and the second outer shell 120, respectively.

In the first elastic fabric 115 and the second elastic fabric 122 to be described later, only the portion sewn by the first thread member S1 and the second thread member S2 is compressed, and the non-sewn portion has an original thickness. maintain.

The friction fabric 116 is a material having a higher coefficient of friction than the first elastic fabric 115 and the second elastic fabric 122 described below, and is disposed between the first elastic fabric 115 and the second elastic fabric 122. And, it can prevent the first elastic fabric 115 and the second elastic fabric 122 from slipping.

The second shell 120 forms the other surface of the charyeop comforter 100.

The second shell 120 includes at least one first fine particle (not shown) selected from the group consisting of silver, selenium, and zinc, and germanium, tungsten, silicon dioxide (Silica, silicon dioxide), and titanium dioxide (TiO2). , And mixing one or more second fine particles (not shown) selected from the group consisting of aluminum oxide (Al 2 O 3 , Aluminum oxide), and treating the first fine particles and the second fine particles to a thread of cotton material to antibacterial It can be manufactured by treating, mixing antibacterially treated yarn and glass fiber to weave an antibacterial fiber fabric, and arranging cotton fabrics on both sides of the antibacterial fiber fabric.

Here, the glass fiber contains 50 wt% or more to 65 wt% or less of silicon dioxide (SiO2), 10 wt% or more to 20 wt% or less of aluminum oxide (Al2O3), and 5 wt% of calcium oxide (CaO) based on the total weight of the glass fiber. % or more to 15 wt% or less, magnesium oxide (MgO) of 5 wt% or more to 15 wt% or less, and titanium dioxide of 0.1 wt% or more to 0.8 wt% or less.
