As shown in FIGS. 2 to 3, the undergarment includes a body contact member 10 having a predetermined length along a contact portion in contact with the body in the undergarment, and allowing the secretion secreted by the contacted body to pass inward; An absorbent pad (20) inside the body contact layer absorbing secretions and functioning; The absorbent pad 20 may be made of any one of silicone rubber, thermoplastic elastomer, urethane foam, ethylene vinyl acetate (EVA) foam, natural rubber (NR), natural rubber foam, ethylene propylene diene monomer ) 100 weight of a foamable resin which is a mixture of at least one member selected from the group consisting of rubber, chloroprene rubber (CR), latex, acrylonitrile-butadiene rubber (NBR), butyl rubber, and polyvinyl chloride Polyacrylic acid-polyvinylalcohol graft polymer, sodium carboxy methycellulose, polyacrylic acid and natural polymer (polyacrylic acid-starch graft polymer) obtained by graft-polymerizing starch onto polyacrylic acid, polyacrylic acid-polyvinylalcohol graft polymer, Of a graft polymer, and a mixture of polyacrylic acid and polyvinylamine. 5 to 30 parts by weight of a ninth polymer and 50 to 100 parts by weight of bentonite or sodium bentonite and at least one member selected from the group consisting of tetramethylthiuram disulfide (TT), dipentamethylenethiuram tetrasulfite (TRA) 1 to 10 parts by weight and 0.5 to 10 parts by weight of an antibacterial deodorant in an aqueous solution state selected from the group consisting of titanium oxide, nano-particles, quartz stone, and inorganic antibacterial deodorant having a nano- Structure.

5 to 30 parts by weight of a high-adsorptivity polymer, 50 to 100 parts by weight of an inorganic filler, 1 to 10 parts by weight of a flour and an anti-microbial deodorant, based on 100 parts by weight of the foamable resin of the present invention, Elastomers such as Thermo Plastic Elastomer, urethane foam, EVA (Ethylene Vinyl Acetate) foam, natural rubber (NR), natural rubber foam, ethylene propylene diene monomer rubber, chloroprene rubber, Latex, acrylonitrile-butadiene rubber (NBR), butyl rubber, or a mixture of two or more thereof.

The superabsorbent polymer may be a polyacrylic acid polymer, a polyacrylic acid-starch graft polymer obtained by graft-polymerizing starch onto polyacrylic acid, a polyacrylic acid-polyvinylalcohol graft polymer, a sodium carboxy methylcellulose methycellulose, a graft polymer of polyacrylic acid and a natural polymer, and a mixture of polyacrylic acid and polyvinylamine, and more preferably a polyacrylic acid polymer (also referred to as sodium polyacrylate) is used It is good.

The mixing amount of the superabsorbent polymer is 5 to 30 parts by weight, preferably 10 to 25 parts by weight, of the superabsorbent polymer per 100 parts by weight of the foamable resin. If the mixing amount of the polymer is less than 5 parts by weight, it is difficult to obtain satisfactory water absorption. If the mixing amount exceeds 30 parts by weight, the physical properties of the resin may deteriorate.

The inorganic filler may be either bentonite or sodium bentonite. Preferably, bentonite is used, and more preferably bentonite having an average particle size of 150 to 200 mesh is used.

The mixing amount of the inorganic filler is 50 to 100 parts by weight of an inorganic filler based on 100 parts by weight of the resin and the foamable resin. More preferably 50 to 80 parts by weight. If the mixing amount of the inorganic filler is less than 50 parts by weight, a certain water absorption rate can be obtained to some extent due to the characteristics of the material. However, it is difficult to obtain a desired satisfactory water absorption rate in the present invention, The water absorption rate is too high, so that the swelling rapidly occurs, and the problem of the loss of the function as the absorption pad occurs, and the user's discomfort can be rather increased.

The vulcanizing agent may be selected from the group consisting of DM, TT, TRA, sulfur and amines. The amount of the vulcanizing agent is 1 to 10 parts by weight based on 100 parts by weight of the resin and the foamable resin. If the mixing amount of the vulcanizing agent is less than 1 part by weight, there is a problem in the vulcanization temperature and the vulcanization time, and if it is used in excess of 10 parts by weight, there is a risk of scorching in storage

The vulcanizing agent not only lowers the vulcanization temperature of the resin composition of the present invention, shortens the vulcanization time but also improves physical properties of the vulcanized product.

An antibacterial deodorant may be added to the resin composition to increase the antibacterial deodorizing power.

The antimicrobial deodorant may be added in any form so long as it does not impair the present invention, but preferably the antibacterial deodorant is selected from the group consisting of titanium oxide (TiO2), silver nano, elvan, and loess Or a mixture of two or more selected from these, and more preferably, one having a nano-sized particle size is used. And more preferably a particle size of 10 nm or less. More preferably, the antibacterial deodorant is added and mixed in an aqueous solution.

Preferably, the antibacterial deodorant is added in an amount of 0.5 to 10 parts by weight, more preferably 0.5 to 5 parts by weight, based on 100 parts by weight of the resin composition of the present invention described above. If it is added below the minimum value, it is difficult to obtain a satisfactory antibacterial deodorizing power of the antimicrobial deodorant to be added. If it is added in excess of the maximum value, the antimicrobial deodorizing power is excellent, And the productivity may be lowered.

By further adding the antibacterial deodorant, it is possible to solve the difficulty of complete deodorization and antibacterial treatment only by absorbency.

An antibacterial deodorant may be further added to the resin composition to increase the antibacterial deodorizing power. The antimicrobial deodorant may be added as long as the antimicrobial deodorant does not impair the present invention. Preferably, the antimicrobial deodorant is one selected from the group consisting of titanium oxide (TiO 2), silver nano, zeolite, Or a mixture of two or more selected from these, and more preferably, one having a nano-sized particle size is used.

Preferably, the amount of the antibacterial deodorant to be added is 0.5 to 10 parts by weight, more preferably 0.5 to 5 parts by weight, based on 100 parts by weight of the resin composition of the present invention. If it is added below the minimum value, it is difficult to obtain a satisfactory antimicrobial deodorizing power with the added antimicrobial deodorant. When the antimicrobial deodorant is added in excess of the maximum value, the antimicrobial deodorizing power is excellent but it may result in inhibition of water absorption. And the productivity may be lowered

The absorbent pad 20 according to the present invention described above is prepared by mixing the mixture at the ratios shown in Table 1, melting the mixture at a melting temperature of 120 DEG C in a melting machine, Mm, length × width = 300 × 300 (mm), and a typical fabric was adhered to one surface to be bonded to prepare a test piece.
