The present invention relates to a far-infrared radiation pad, and more particularly, to provide a pad material with breathability for easy ventilation and by providing a far-infrared radiation material therein so that the user can see the effect of far-infrared radiation. .

In general, pads are embedded in bras to compensate women's poor breasts or for various purposes, such as body protectors to protect the body such as knees, ankles, wrists, shoulders, shins and elbows, and helmet protectors to protect the head. It is used in various ways.

Particularly, in the case of a bra, a cup is formed to protect the breasts, and in recent years, a pad has been proposed to enhance the beauty effect of making the breasts appear larger. The pads are made of a soft cloth-like material, with no special effect expected, but simply to make the breasts bigger, just a thicker cup of bra.

As such, when a pad having a constant thickness is inserted into an existing bra, a protective effect of the chest may be obtained. However, when the user presses the chest, when worn for a long time, a feeling of tightness is caused by a feeling of pressure due to a decrease in breathability, and blood circulation is caused by compression. It does not go smoothly, and other diseases, such as mastitis or breast cancer, may occur.

In addition, the pad used for protection of each part of the body also exhibits the same problems due to the feeling of pressure.

The present invention has been proposed to improve the above problems in the prior art, so that the far infrared rays can be irradiated to the human body when using the pad to facilitate the blood circulation of the human body and to allow ventilation with the outside. The purpose is to maximize the convenience of use when used as a bra and body protector.

The object is provided between the lower pad layer and the upper pad layer, the far infrared radiation unit is provided, the far infrared radiation unit can be achieved through the far-infrared radiation pad laminated structure, characterized in that the powder material for emitting a large amount of far infrared rays formed in the form of a point. Will be.

In addition, forming a far-infrared radiation portion for forming a far-infrared radiation material in a powder state by using a screen net on the upper surface of the lower pad layer; An upper and lower pad layer bonding step of mounting an upper pad layer on an upper portion of the lower pad layer; It is possible to achieve through the far-infrared radiation pad manufacturing method comprising a; fusion step of fusion between the upper, lower pad layer by hot pressing the upper and lower pad layer to the pad molding mold.

Hereinafter, specific embodiments of the present invention will be described in detail with reference to the accompanying drawings.

First, a manufacturing process of a pad for a bra according to an embodiment of the present invention will be described with reference to the flowchart of FIG. 1, the process of FIG. 2, and FIGS. 3 and 4.

<ST 1: Screen mounting stage>

In the state where the lower pad layer 10 is prepared from a conventional porous sponge material, the screen net 40 having a plurality of through-holes 41 formed thereon is seated thereon.

When the screen net 40 is based on the total surface area, the ratio between the through-hole 41 and the non-hole 42 formed through the upper and lower portions as shown in FIG. 3 satisfies the range of 20 to 35%: 80 to 65%. It is preferable to use the one manufactured to, but if the ratio occupied by the through-hole 41 is less than 20%, the far-infrared radiation portion to be formed in the lower pad layer 10 is relatively small, so that the desired far-infrared effect cannot be exhibited. If it exceeds 35%, the pad fusion surface 21 is reduced, which may cause a problem that the upper and lower pad layers 10 and 20 are easily separated when the pad is completed.

<ST 2: Formation of Far-Infrared Radiation Part>

Subsequently, when a predetermined amount of the far infrared radiation powder 31 is sprayed and applied to the upper portion of the screen net 40, the far infrared radiation powder 31 is introduced through the through-hole 41 of the screen net 40. .

In this case, the far-infrared radiation powder 31 to be applied is preferably used a material exhibiting a far-infrared radiation effect, such as ocher, tourmaline or nanosilver.

In particular, the tourmaline of the above components is commonly called tourmaline, and is used as a jewel as a hexagonal tablet having a hardness of 7.25 and a specific gravity of 3.05. Tourmaline has a refractive index of 1.62 to 1.64, birefringence of 0.018, and color in seven colors including green and blue. Such tourmaline is piezoelectric, and when a vertical pressure or shear stress is applied by a human hand or other tool, the surrounding water molecules are separated into hydrogen ions and hydroxyl ions. At this time, hydrogen ions are attracted to the cathode potential of the tourmaline. It is known to have the property of generating negative ions while being released into the air in the state.

In addition, in the case of nano silver, it is preferable to use nano silver having a particle size in the range of 100 to 250 nm to prevent precipitation phenomenon. When nano silver is used, it can exhibit anti-microbial and antiseptic and antistatic effects as well as far infrared radiation effect. Particularly, when the particle size of the nano silver powder is 100 nm or less, the particles are too light to prevent the far-infrared radiation portion 30 from being formed in a point shape, and when the particle size is 250 nm or more, voids are formed between the powder particles to show a protrusion on the pad surface. Problems may arise.

<ST 3: Screen Removal Step>

Meanwhile, when the screen net 40 is removed after the application of the far-infrared radiation powder 31, the far-infrared radiation portion 30 appears in the form of a dot on the upper surface of the lower pad layer 10.

At this time, the far-infrared radiation unit 30 is formed at a position corresponding to the through-hole 41 of the screen net 40. At this time, since the powder remains as it is, attention is required because the powder may spread when vibration or flow occurs.

<ST 4: upper pad seating stage>

Subsequently, by mounting the upper pad layer 20 on the lower pad layer 10, the far infrared ray radiating part 30 is formed to be protected in the middle formed at regular intervals between the upper and lower pad layers 10 and 20.

<ST 5: Pad Fusion Step>

Then, by using the molding mold 50 consisting of the upper mold 51 and the lower mold 52, the upper and lower pad layers 10 and 20 are pressurized to a predetermined temperature to perform a welding operation in an integrated structure. .

That is, in this case, the upper mold 51 is placed on the upper and lower pad layers 10 and 20 on the lower mold 52 forming the concave curved space portion 52a for forming into a pad shape. When the upper and lower molds 51 and 52 are pressurized, the pads are formed in the same shape because the upper and lower molds 51 and 52 are spaced apart by a predetermined height d due to the space 52a.

Particularly, in the cross-sectional shape of the space portion 52a, the height d gradually decreases from the center to the periphery, so that a higher pressing force can be applied around the pad to improve the welding performance. do.

In addition, the temperature of the molding mold 50 is preferably carried out at 90 ~ 130 ℃, if pressurized fusion at a temperature of 130 ℃ or more may be carbonized far-infrared radiation, pressurized fusion at a temperature of 90 ℃ or less If made, the fusion performance between the lower pad layer 10 and the upper pad layer 20 is lowered, which may cause a problem of mutual separation in use.

In particular, the molding mold 50 has the upper mold 51 in the range of 110 to 130 ° C, and the lower mold 52 in the range of 90 to 110 ° C, that is, the upper mold 51 is lower than the lower mold 52. It is preferable to set it to a high temperature, which squeezes the upper pad layer 20 to a higher temperature than the lower pad layer 10 to which the far-infrared radiating part 30 is directly attached, thereby maximizing the melting effect, while being far infrared due to the high temperature. This is to minimize the adverse effect on the radiating portion 30.

<ST 6: Cutting Molding Step>

In the final process, the molding of the pad is completed by cutting the rim side of the pad of the present invention in which the integral fusion is made through the above process in the form of a bra pad.

5 and 6 show a pad for a bra completed according to an embodiment of the present invention, as shown, a plurality of upper and lower pad layers (10, 20) between the far-infrared radiation portion 30 is not exposed to the outside By being provided in the form of a dot can always exhibit a stable far-infrared radiation effect.

In other words, the anion that is continuously generated increases the activity of alpha waves in the brain, inhibits serotonin and free histamin, helps to relax tension, cleanses the blood, activates cells, and immunity in serum By increasing the amount of r-globlin (r-globlin) as a component to increase the resistance, it is possible to prevent the occurrence of atopic skin disease caused by the sick house syndrome, especially in urban apartment environment.

In particular, when nanosilver is used as the far-infrared radiation material, it can exhibit additional effects such as antistatic effect, skin sterilization effect against fungi and virus, and skin cell activation.

In addition, as one of the features of the pad product of the present invention by forming a pure far-infrared radiation powder in the form of a point without using a chemical agent such as a separate adhesive fusion between the far-infrared radiation portion 30 as shown in the enlarged main portion of FIG. By forming (21), it does not cause dermatitis such as atopic dermatitis.

In addition, although specific embodiments of the present invention have been described and illustrated above, it is obvious that the pad manufacturing process and the lamination structure of the present invention may be variously modified and implemented by those skilled in the art.

For example, the embodiment described and illustrated as an example of a pad for a bra, it can be applied to the manufacture of a pad product for the protection of the other body.

Therefore, such modified embodiments should not be understood individually from the technical spirit or the prospect of the present invention, and such modified embodiments should fall within the appended claims of the present invention.

As described above, the present invention allows continuous radiation of far-infrared rays to be made in a pad in direct contact with the body, thereby exhibiting a beneficial effect on the human body.

In particular, the far-infrared radiation layer is provided so as not to be exposed to the outside to improve the durability of the product to exhibit a more stable far-infrared radiation effect can be maintained.

In addition, by providing a far-infrared radiation portion in the form of a dot to enable the bonding according to the fusion between the upper and lower pad layer, and do not use a mixture of chemicals, such as a separate adhesive material, to improve the safety and reliability of the product do.

In addition, the pad is provided with a highly breathable sponge material, and the upper and lower parts are fused, thereby improving the wearing comfort.

In addition, the use of nanosilver as a far infrared ray radiating material shows the advantage that the sterilization and antibacterial function can be added to the skin area where direct contact is made, as well as the far infrared ray radiating effect.
