The antimicrobial dehumidifying agent has a hygroscopicity higher than that of a conventional hygroscopic agent such as silica gel and the volume increase rate due to moisture absorption can be greatly reduced by including the hygroscopic agent, aluminum magnesium silicate and antibacterial agent within the above range. In addition, by including the deodorizing function minerals and the aluminum chloride hexahydrate in the above content range, the deodorizing function can be imparted and the sweat absorbability can be improved.

More specifically, the antimicrobial dehumidifying agent has excellent hygroscopicity, excellent antimicrobial activity, and reduced volume expansion due to moisture absorption, compared with a conventional hygroscopic agent. Thus, it has an excellent antimicrobial hygroscopicity and an excellent durability. Also, by providing a laminated sheet in the form of a sticker that can be attached to the insole of an insole by producing an adhesive laminated sheet including a polyolefin film containing such an antibacterial dehumidifying agent, it is possible to provide a laminated sheet having excellent durability and excellent deodorization and antimicrobial agent wettability, Can be provided.

Each composition of the antibacterial dehumidifier of one embodiment of the present invention will be described below.

The hygroscopic agent of the antibacterial hygroscopic agent of one embodiment of the present invention plays a role of absorbing moisture of the external environment (air, etc.).

Specific examples of the moisture absorbent include polyacrylamide, polyacrylic acid, polyvinyl alcohol, and the like having hydrophilic groups in the polymer, which are excellent in hygroscopicity and are often called superabsorbing polymers. Carboxymethyl cellulose, alginate, carboxymethyl alginate and the like, which are highly hygroscopic.

In the antibacterial hygroscopic agent of one embodiment of the present invention, polyacrylamide or carboxymethyl alginate may be preferable when considering the hygroscopicity and the volume expansion due to moisture absorption.

In the antibacterial hygroscopic agent of one embodiment of the present invention, the content of the hygroscopic agent may be 1 to 5% by weight based on 100% by weight of the antibacterial hygroscopic agent.

If the content of the hygroscopic agent is high, the hygroscopic property may be improved. However, the volume increase rate of the antibacterial hygroscopic hygroscopic agent due to moisture absorption is increased, and when the material is used as a material adhered to the insole of a shoe, There is a problem that sufficient antibacterial dehumidification, deodorization, and sweat absorption effects are difficult to be realized.

The aluminum magnesium silicate of one embodiment of the present invention has hygroscopicity itself and can act as a buffer to suppress the volume expansion of the hygroscopic agent such as polyacrylamide.

When the antibacterial dehumidifying agent has a large volume expansion property, when the material containing the antibacterial dehumidifying agent of the present invention is provided on the insole portion of the shoe for removing foot odor, there is a possibility that the wearing comfort of the shoe may be deteriorated over time, The physical load applied to the microporous membrane becomes large, resulting in physical destruction, which may result in difficulty in achieving sufficient antibacterial dehumidification, deodorization, and sweat absorption.

Therefore, it is necessary to suppress the volume expansion of the antibacterial dehumidifying agent.

Specifically, the aluminum magnesium silicate is included in the antibacterial moisture absorber to physically inhibit the volume expansion of the hygroscopic agent when the antibacterial hygroscopic agent absorbs moisture, or to increase the hygroscopic property of the antibacterial hygroscopic agent itself, It is believed that it can contribute to minimizing swelling.

As is also supported by the examples described later, it was confirmed that when the proper amount of aluminum magnesium silicate is contained, the hygroscopicity of the antibacterial hygroscopic agent is greatly improved and the volume increase due to moisture absorption is suppressed.

The content of the aluminum magnesium silicate in the antibacterial hygroscopic agent of one embodiment of the present invention may be 1 to 3% by weight based on 100% by weight of the antibacterial hygroscopic agent.

If the content of the aluminum magnesium silicate is too small, the volume expansion rate of the antibacterial hygroscopic agent may be insufficient because the effect of inhibiting the volume expansion of the antibacterial hygroscopic agent is insufficient. If the content of aluminum magnesium silicate is too large, aluminum magnesium silicate may not act as a buffer against volume increase, and the volume increase rate of the antibacterial hygroscopic agent due to moisture absorption may increase. This is because aluminum magnesium silicate itself has a large amount of moisture absorption It is considered that the increase in the volume of the aluminum magnesium silicate itself is caused largely.

Accordingly, the content of aluminum magnesium silicate may be preferably 1 to 3% by weight based on 100% by weight of the antibacterial moisture absorber.

The antimicrobial agent of the antibacterial hygroscopic agent of one embodiment of the present invention can prevent the propagation of microorganisms near the antibacterial hygroscopic agent and can kill (kill) microorganisms.

Examples of the antimicrobial agent include menthol, isopulegol, menton, camphor, pegolol, cineol, mint oil, N-alkyl-p- menthan-3-carboxamide, p- menthan- 1-ol, 1- (2-hydroxy-4-menthylcyclohexyl) -ethanone, menthyl lactate, menthol glycerol ketal, N-methyl- 3-dimethylbutanamide, menthyl succinate, menthyl glutarate, peppermint oil, eucalyptus oil, spearmint oil, vanillyl ethyl ether, vanillyl propyl ether, vanillin propylene glycol acetal, ethyl vanillin propylene glycol acetal, capsaicin, (1-menthoxy-methyl) -2- (3 ', 4'-dihydroxyphenyl) -1,3- Phenyl) -1,3-dioxolane, 4- (1 -methoxymethyl) -2- (2'-hydroxy- -Methoxymethyl) -2- (4'-methoxyphenyl) -1,3-dioxolane, 4- (1-menthoxy-methyl) Phenyl) -1,3-dioxolane, 4- (1-menthoxy-methyl) -2- (3'-methoxy-4'-hydroxyphenyl) ) -1,3-dioxolane, red pepper oil, red pepper oleoresin, vanillyl amidonylate, ambau oleorecin, Japanese pepper extract, α-acidol, β-acidol, , ≪ / RTI > < RTI ID = 0.0 > pyrazole, < / RTI >

Concretely, it may be? -Saccharide or? -Saccharide, more specifically? -Saccharide having excellent antibacterial activity.

In the antibacterial hygroscopic agent of one embodiment of the present invention, the content of the antibacterial agent is not particularly limited, but may be 1 to 3% by weight based on 100% by weight of the antibacterial hygroscopic agent. In view of the above, it is preferable that the above range is sufficient considering the adequate content of the hygroscopic agent for moisture absorption, the aluminum magnesium silicate, the minerals described later, the aluminum chloride hexahydrate and the binder resin.

The content of the mineral in the antibacterial hygroscopic agent of one embodiment of the present invention is not particularly limited but may be 1 to 2% by weight based on 100% by weight of the antibacterial hygroscopic agent. When the appropriate range of the hygroscopic agent for moisture absorption, aluminum magnesium silicate, antibacterial agent, aluminum chloride hexahydrate to be described later, and binder resin is considered together, the above range may be preferable.

The aluminum chloride hexahydrate of the antibacterial hygroscopic agent of one embodiment of the present invention serves to absorb and remove sweat.

The content of the aluminum chloride hexahydrate in the antibacterial hygroscopic agent of one embodiment of the present invention is not particularly limited but may be 1 to 2% by weight based on 100% by weight of the antibacterial hygroscopic agent. The above range can be sufficient if sufficient sweat absorbing action is possible and the appropriate contents of the moisture absorber for moisture absorption, aluminum magnesium silicate, antibacterial agent, mineral and binder resin to be described later are considered together.

The binder resin of the antibacterial hygroscopic absorbent of one embodiment of the present invention may serve as a body of the antibacterial hygroscopic agent and may serve to bind the hygroscopic agent, aluminum magnesium silicate, antibacterial agent, mineral, and aluminum chloride hexahydrate to each other.

The binder resin may be, for example, linear low density polyethylene (LLDPE), low density polyethylene (LDPE), polypropylene (PP) or the like. More specifically, linear low density polyethylene (LLDPE) may be preferable from the viewpoint of compatibility with the material of the polyolefin film in which the binder performance and the antibacterial moisture absorber are mixed.

The binder resin constitutes the remainder of the antibacterial hygroscopic agent. For example, the binder resin may include 40 to 99% by weight based on 100% by weight of the total amount of the antibacterial hygroscopic agent.

The antibacterial hygroscopic agent according to one embodiment of the present invention having the above composition has excellent hygroscopicity, excellent antimicrobial properties and reduced volume expansion due to hygroscopicity compared to a conventional hygroscopic agent such as silica gel. Thus, it has an excellent antimicrobial hygroscopicity and an excellent durability. Specifically, the antibacterial moisture absorber may have a weight increase rate of 50% or more after exposure to air at 25 ° C and a relative humidity of 90% for 20 hours. Here, the weight increase rate refers to the amount of moisture absorbed, and the larger the weight increase rate, the better the hygroscopicity. More specifically, the weight increase rate may be 60% or more, 70% or more, or 75% or more, and the upper limit may be 100% or less, though not particularly limited.

In addition, the antibacterial moisture absorber may have a volume increase rate of 5% or less after exposure to air at 25 캜 and a relative humidity of 90% for 20 hours. Here, the volume increase rate represents the degree of volume increase due to moisture absorption, and the smaller the volume increase rate is, the better. More specifically, the volume increase rate may be 4% or less, or 3.5% or less. The lower limit is not particularly limited, but may be 0.5% or more, or 1% or more.

Also, by providing a laminated sheet in the form of a sticker that can be attached to the insole of an insole by producing an adhesive laminated sheet including a polyolefin film containing such an antibacterial dehumidifying agent, it is possible to provide a laminated sheet having excellent durability and excellent deodorization and antimicrobial agent wettability, Can be provided.

Such a polyolefin film may be produced by melt-extruding the antibacterial dehumidifier of the present invention containing a polyethylene-based resin as a binder resin to form a film, but the elongation or tensile strength of the film produced with a small polyolefin content may be insufficient have.

Thus, it is possible to produce a multi-layer type film in which a separate polyolefin resin composition and a composition containing the antibacterial dehumidifying agent are co-extruded to form a film in which the antibacterial dehumidifying agent is incorporated in the polyolefin resin, Lt; / RTI >

At this time, the polyolefin film of the present invention may contain 0.5 to 2% by weight of the antibacterial dehumidifying agent, based on 100% by weight of the polyolefin film. In view of realizing a sufficient elongation or tensile strength of the polyolefin film within the above range, the antimicrobial property, the dehumidification property, the deodorizing property and the sweat absorbing property can be realized according to the antibacterial dehumidifier characteristic of the present invention.

In Table 1, the weight% is the weight percentage of each material based on the total weight of the raw material of 100 wt%.

[Experimental Example]

The moisture absorption of the antimicrobial dehumidifying agent of Examples 1 to 4 and Comparative Examples 1 to 5 and the volume change ratio after moisture absorption were measured and the results are shown in Table 2 below.

The desiccation experiments were carried out using desiccators and exposed to air for 20 hours after filling with air at a temperature of 25 ° C and a relative humidity of 90% prepared using a thermo-hygrostat (AGO-224).

Example 1 Example 2 Example 3 Example 4 Comparative Example 1 Comparative Example 2 Comparative Example 3 Comparative Example 4 Comparative Example 5 Moisture absorption amount

As can be seen from the above Table 2, in the case of Examples 1 and 4 satisfying the composition of the present invention, the moisture absorption amount was increased by more than 2 times and the volume increasing rate after moisture absorption was 1/6 as compared with the silica gel (Comparative Example 5) It can be seen that it is lowered.

In the case of Comparative Example 1 in which the amount of the moisture absorbent is less than the range of the present invention, the volume increase rate is low but the moisture absorption amount is small. In the case of Comparative Example 2 in which the amount of the moisture absorbent is larger than that of the present invention, The growth rate was too big.

In Comparative Example 3, the amount of aluminum magnesium silicate was too small to sufficiently function as a buffer for volume increase. In Comparative Example 4, the amount of aluminum magnesium silicate was too large, This is considered to be the reason why the volume increase of the silicate itself is largely increased.
