DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, a method for manufacturing a functional elastic interior material according to preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

1 is a flowchart showing a method for manufacturing an elastic inner material according to the present invention.

Referring to FIG. 1, the method for producing an elastic inner material according to the present invention includes a step S100 for producing a mixture by mixing a foamable synthetic resin and a sericite composition, an application step S200 for applying the mixture to a fabric, And a foaming step (S300) of heating and foaming the mixture applied to the fabric.

When such a method for producing an elastic inner material is used, a functional elastic inner material can be produced. More specifically, the functional elastic interior material is composed of a fabric, a mixture formed by mixing the foamed synthetic resin and a sericite composition, and the foamed synthetic resin is provided in a state of being foamed on the fabric.

Hereinafter, each component will be described in more detail with reference to the drawings.

Referring to FIG. 1, a method for manufacturing an elastic inner material according to the present invention includes a step S100 of producing a mixture.

The mixture forming step S100 is a step of mixing a foamable synthetic resin for providing a restoring force and a cushion to the elastic inner material, and a sericite composition for providing far-infrared rays and negative ions to produce a mixture.

Any synthetic resin having foamability by heat may be used as the foamable synthetic resin, but it is preferable to use any one of PVC, EVA and PU.

Specifically, the foamable synthetic resin may include 60 parts by weight of PE-1311 (LG Chem) and 40 parts by weight of LP-090 (manufactured by LG Chemical). In another embodiment, the foamable synthetic resin may be constituted to include 85 parts by weight of LP-170 (manufactured by LG Chemical) and 15 parts by weight of LB-110 (manufactured by LG Chemical).

In addition, the sericite composition may include 50 to 100 parts by weight based on 100 parts by weight of the foamable synthetic resin. Here, only the sericite may be pulverized. However, it is also possible to use a certain amount of water. However, the water is eco-friendly, colorless, tasteless, odorless, and can be soft water, distilled water, deionized water or purified water.

At this time, the amount of water used is not particularly limited, and can be adjusted depending on the kind of the other constituent elements and the amount thereof to be used, the molding method or use of the desired sericite composition. The water may be used in a wide range, for example, in the range of about 15 to 75% by weight, preferably 25 to 45% by weight, based on 100% by weight of the sericite composition.

If the content of water in the above-mentioned sericite composition is less than 15% by weight, the individual components of the sericite composition are not easily mixed. If the content of the components is less than 15% by weight,

The above-mentioned sericite powder has a function of promoting blood circulation of the human body, releasing 90% or more of far-infrared rays for activating cell activity, absorbing various harmful substances by emitting strong anions, By weight and 20 to 80% by weight in powder form.

If the content of the sericite powder is less than 20% by weight, sufficient anion and far-infrared rays can not be provided to the user. If the content of the sericite powder exceeds 80% by weight, components of the sericite composition are not easily mixed.

This sericite is a type of clay minerals, the color of which is silver white, and the silk gloss is strong. Mineralogically, it belongs to the mica group. Its chemical composition and crystal structure are similar to muscovite, the far-infrared emissivity is about 93%, the anion generation is about 700 / cc and the safest anion, It has a function to adsorb various harmful substances. It is also known that the sericite has an alkaline pH of 8.8, so it has excellent antioxidant and neutralizing action at acidified sites.

Far infrared rays emitted from the sericite infiltrate skin cells to cause air-conditioning vibration in water molecules of each cell to activate cell tissue to promote metabolism of the human body, improve blood circulation, and enhance deodorizing power. In addition, sericite radiates alpha (α) waves to inhibit harmful bacteria generation by more than 70%, adsorbs and decomposes heavy metals, organic matter, odor and germs, and provides abundantly beneficial minerals to the human body.

In addition, the molecular composition of sericite is KAl ₂ (AlSi ₃ O ₁₀ ) (OH) _2, and the contents of silicon dioxide (SiO ₂ ), aluminum oxide (Al ₂ O ₃ ), potassium oxide (K ₂ O) And iron oxide (Fe ₂ O ₃ ), magnesium oxide (MgO), and sodium oxide (Na ₂ O).

For example, the potassium oxide reacts with water in the air to emit high heat, in which ionizing energy is generated. And magnesium oxide reacts with water to become magnesium hydroxide with a large volume, and this material action also generates ionization energy. In addition, sodium oxide reacts violently with water and changes to sodium hydroxide, and ionization energy is generated in this process.

In this way, due to the nature of the components of the sericite reacting with water, it performs active ion exchange with the moisture in the air. As a result, the negative ions (O ^2- ) are released to combine with the cations present in the room air, do.

Generally, electrolytic decomposition is carried out to electrically ionize the material. However, sericite is ionized, that is, electrolysis occurs inside the mineral due to the reaction of the components of potassium oxide, calcium oxide, iron oxide, magnesium oxide and sodium oxide with water do.

As a result, the ore water composition coating layer reacts with moisture (moisture) in the room air to emit negative ions (O ^2- ), and the negative ions attract and attract cations distributed in the air to generate oxygen.

When the average grain size of the sericite powder is less than 325 mesh, the mixture of water and sericite powder does not gel properly. When the average grain size of the sericite powder exceeds 1,000 mesh The physical properties of the sericite composition are not improved in comparison with the crushing cost of the sericite powder.

Such other additives include plasticizers, foaming agents, thickeners, stabilizers, antimicrobial agents, and the like, which are added to the sericite composition to improve the flowability or to enhance the properties of the mixture composed of the foamable synthetic resin and the sericite composition. These fillers may be used in an amount of 70 to 85 parts by weight of a plasticizer, 2 to 7 parts by weight of a foaming agent, 0.01 to 1 part by weight of a thickener, 2 to 4 parts by weight of a stabilizer, and 3 to 7 parts by weight of a colorant, based on 100 parts by weight of the foamable synthetic resin.

As the plasticizer, DINP (LG Chemical) or an environmentally friendly plasticizer GL-300 (LG Chemical) may be used.

Specifically, the dispersant may be an acrylic acid copolymer sodium salt, a carboxylic acid ether, an aromatic aminosulfonic acid, a polyalkylarylsulfonic acid, or a naphthalenesulfonic acid, preferably an acrylic acid copolymer sodium salt It is recommended to use SOKALAN PA 30 from BASF GmbH in Germany. If the content of the dispersing agent is less than 0.1% by weight, the dispersing ability is lowered and it is difficult to produce a uniform composition. If the content of the dispersing agent is more than 1% by weight, if it is used excessively,

The antibacterial agent powder may be an antibacterial agent commonly used in the art, preferably propolis, phytoncide extract or a mixture thereof. If the content of the antibacterial agent powder is less than 0.7% by weight, the antimicrobial activity of the sericite composition is lowered. If the content of the antibacterial agent powder exceeds 2% by weight, the mechanical properties of the sericite composition are lowered and the cost is increased.

The fragrant powder is contained in the composition to provide a fragrance to stabilize the mind and body of the user, improve the satisfaction and provide a sterilizing function, and includes 0.1 to 2 parts by weight based on 100% by weight of the composition of the warp knit composition. If the fragrance powder is used in an amount of less than 0.1 wt%, the addition effect is insignificant. If the fragrance powder is used in an amount of more than 2 wt%, the fragrance powder may cause an unpleasant feeling to some users.

As the fragrant powder, a completely dried pine leaf powder or a herb powder may be used. Specifically, the pine needle powder contains a terpene pherine rich system, and generates negative ions as its own, and provides a soleplate to stabilize the mind and body of the user and improve the satisfaction.

Referring to FIG. 1, a method of manufacturing an elastic inner material according to the present invention includes an applying step S200.

The applying step (S200) is a step of applying the mixture produced through the mixture producing step to the fabric, and the impregnation method or the like may be used.

Here, the fabric is used as a base material of an elastic inner material, and a fabric composed of materials such as PE, acrylic resin, and PVC is used to prevent carbonization by foaming and to provide durability over a certain level. At this time, the fabric preferably has a network-like structure to provide air permeability.

Further, the fabric uses a fabric composed of yarns of 10 to 200 denier (D) so that durability and air permeability can be controlled depending on the use of the elastic inner material. For example, when a fabric composed of a yarn of 200 denier is used, the space between the yarns is widened as shown in Figs. 2 and 3 to increase air permeability and durability. However, if a fabric of 10 denier yarns is used, As a result, the space between the chambers is reduced, thereby decreasing the air permeability and improving the durability.

In this case, when a fabric composed of yarns of less than 10 denier is used, comfort due to breathability can not be provided, and when a fabric composed of yarns of more than 200 denier is used, the restoring force is lowered and durability is deteriorated.

Referring to FIG. 1, the method for manufacturing an elastic inner material according to the present invention includes a foaming step (S300).

The foaming step S300 is a step of heating the fabric to foam the mixture applied to the fabric through the application step to foam the mixture applied to the fabric and placing the fabric coated with the mixture inside the furnace And at a rotation speed of 1000 to 2000 RPM in a temperature range of 150 to 300 degrees. At this time, the time for performing the high-temperature treatment process may be varied depending on the thickness of the elastic inner material, and therefore is not particularly limited.

Hereinafter, specific examples and experimental examples of the present invention will be described in more detail. It should be understood, however, that the embodiments and examples are for the purpose of promoting understanding of the specific examples of the invention described above, and the scope of rights and the like should not be construed thereby.
