When the front outer fabric 210 and the front inner fabric 220 are joined to each other, a bra cup 230 having a cushioning force is embedded in the inside of the breast covering portion 210. Here, the bra cup 230 has a protruding shape in the front direction, and when pressed from the front side to the back side, the bra cup 230 is configured to maintain the protruded shape in the rear direction.

The rear bracket 300 includes an equivalent rim portion 301 covering the back portion when the wearer wears the chest, a rear shoulder portion 303 extending upward from the upper end of the equivalent rim portion 301, an equivalent rim portion 301 And a rear inner side fabric 310 having a first color and a rear inner fabric 320 having a second color are laminated with an adhesive, . It is preferable that the rear outer fabric 310 and the front outer fabric 210 have the same first color and the rear inner fabric 320 and the inner front fabric 220 have the same second color. And may be implemented so as to have different colors.

The brassiere front member 200 and the brassiere back member 300 having such a structure are placed so as to face each other with their inner surfaces facing each other so that the end of the front shoulder strap 203 of the brassiere front member 200 and the end of the brassiere back member 300 The end portions of the rear side shoulder portion 303 are connected to each other with an adhesive so that the ends of the both side front side connecting portions 202 of the brassiere front member 200 and the ends of the both side rear side connecting portions 302 of the brassiere back member 300 are connected to each other And is configured to have a shape that can be worn by the wearer on the chest by being connected with an adhesive.

Since the outer and inner surfaces of the brassiere 100 are made of different colors, brassieres of different colors can be realized if the outer and inner surfaces are worn upside down. In addition, the brassiere-free brassiere 100 of the present invention has a good fit because the brassiere 100 is connected to the brassiere by a gluing method without the needles.

Now, a method for manufacturing a double-sided brassiere according to the present invention will be described.

Referring to FIGS. 3 to 4, the brassiere front face member 200 and the brassiere back face member 300 are manufactured and prepared and connected to each other through an adhesive agent.

As shown in FIG. 3, the step of preparing the bra front member 200 includes a breast cover 210 covering the breast when the wearer wears the breast, And a front side connecting portion 202 extending laterally from both sides of the chest covering portion 210. The front outside fabric 10 is made of a first color 210 are prepared.

In addition, the front inner fabric 220 having the same shape as the front outer fabric 210 and made of the second color is prepared.

The front outer fabric 210 and the front inner fabric 220 are then attached to each other by applying the adhesive B1 along the rim between the front outer fabric 210 and the front inner fabric 220, The cup insertion space 204 into which the bra cup 230 is inserted and the cup insertion path 205 through which the bra cup 230 is inserted from the outside into the cup insertion space 204 are not coated with the adhesive B1 So that the cup insertion space 204 and the cup insertion path 205 are formed between the front outer fabric 210 and the front inner fabric 220 by attaching the front outer fabric 210 and the front inner fabric 220 together do.

Then, the bra cup 230 having a cushioning force is inserted into the cup insertion space 204 through the cup insertion passage 205. [ At this time, it is preferable that the cup inserting passage 205 is formed between the front shoulder string 203 and the front side connecting portion 202 so that the bra cup 230 can be inserted diagonally from top to bottom. So that the bra cup 230 can be inserted more easily. The cup insertion passage 205 is formed to be smaller than the diameter of the bra cup 230 so that the bra cup 230 is folded in half and inserted through the cup insertion passage 205, It is preferable that the bra cup 230 inserted in the cup insertion space 204 is configured not to easily escape through the cup insertion passage 205. [

Then, the bra cup front passageway 200 is manufactured by applying the adhesive B2 to the cup insertion passageway 205 to prevent the bra cup 230 from escaping reliably by attaching the cup insertion passageway 205. [

Next, as shown in Fig. 4, the step of preparing the bra backing member 300 includes an equivalent rim part 301 covering the back part when the wearer wears it on the chest, A rear outer shoulder portion 303 extending in an upward direction and a rear side connecting portion 302 extending laterally from both sides of the equivalent rim portion 301 and having a rear outer fabric 310 made of a first color, .

And a rear inner fabric 320 having the same shape as the rear outer fabric 310 and made of a second color.

The backing outer fabric 310 and the backing inner fabric 320 are then bonded to each other with an adhesive B3 therebetween to bond the backing outer fabric 310 and the backing inner fabric 320 together The bra back member 300 is prepared.

When the brassiere front member 200 and the brassiere back member 300 are prepared so that the brassiere front member 200 and the brassiere back member 300 are placed facing each other with their inner surfaces facing each other, An adhesive B4 is applied to the ends of the string portion 203 and the rear shoulder portion 303 of the brassiere back member 300 so as to be connected to each other so that the brassiere front member 200 is connected to both side front side connection portions 202, And an adhesive B4 is applied to the end portions of both side rear side connection portions 302 of the brassiore back member 300 to be connected to each other. This completes the double-sided brassiere.

At this time, the adhesives (B1), (B2), (B3) and (B4) used in the present invention use hot melts. In addition, the adhesive preferably further comprises an antibacterial functional substance.

Here, the hot melt adhesive is preferably a PUR (polyurethane resin) hot melt adhesive, which is generally weak in moisture in the case of a known water-based adhesive.

Particularly, the hot melt should use reactive PUR. In order to maintain the bonding strength, it is preferable that the melting temperature is 120-140 DEG C, the viscosity is 13,000 mPas, and the density is 1.1 g / cm3.

The antimicrobial functional material contained in the hot melt includes 5-10 wt% of the antimicrobial functional material. The antimicrobial functional material is a mixture of prostaglandin and DBNPA (2,2-Dibromo-3-nitrilopropionamide) Citric acid, and borax at a weight ratio of 0.15: 2: 1: 1: 2: 0.5.

At this time, the prostaglandin is a fatty acid derivative having 20 carbons and is added for antiviral function to inhibit viral infection. In addition, the above-mentioned DBNPA (2,2-Dibromo-3-nitrilopropionamide) is added as a liquid antimicrobial agent to enhance the antimicrobial activity. In addition, since the ilite is an anion of clay minerals, it causes coagulation sedimentation by floating neutral particles of positive ions and adsorbs and decomposes heavy metals, toxic gases and harmful substances by the electrical neutralization, and also bacteria, bacteria and fungi It is added for antibacterial, antiviral and sterilization, adsorption and decomposition of toxic substances because of its excellent action and sterilization. The tapioca is a kind of starch obtained from the roots of cassava and has a high adhesive strength and is added for the purpose of enhancing the adhesive strength. In addition, since the carboxyl group is three times higher than the vinegar, the citric acid is not only a natural antibacterial agent having strong sterilizing power, but also has a deodorizing effect and is added for antibacterial deodorization. The borax is added for viscosity control.

The reason for limiting the proportions of the above components is as follows. Prostaglandins have been reported to cause asthma attack in excessive use. Therefore, in order to enhance antibacterial properties, the ratio of liquid antimicrobial agent to citric acid is most preferably the same The viscosity should not be controlled and the viscosity should be controlled with borax. In order to maintain the uniform mixing property, the relative mixing ratio should be maintained as the powdery inorganic material is added.

Therefore, the adhesive used in the present invention has an advantage of realizing antimicrobial and antiviral functions by imparting an antimicrobial property to the adhesive itself in addition to the adhesive function.

In order to test the antimicrobial activity of the adhesive, 0.5 ml of each of the cultured molds was applied to the adhesive agent of the present invention, and the antibacterial activity was tested by counting the viable cells 24 hours before and after 24 hours.

As a result of the test, the number of viable cells was not confirmed after 24 hours in all four sites. Through this, it was confirmed that there is antibacterial property.

Meanwhile, the bra cup 230 used in the present invention uses polychloroprene, which is a high molecular compound made of a polymer of chloroprene as a main raw material. Polychloroprene is a material excellent in durability, ozone resistance, heat resistance, and chemical resistance.

In the present invention, the composition for molding a bra cup is configured as follows so that the elastic restoring force of the polychloroprene can be enhanced and the fatigue limit can be increased to prolong the deterioration cycle to achieve longevity.

That is, the composition for molding a bra cup according to the present invention comprises 2.5-4.5% by weight of styrene-butadiene-styrene (SBS), 4.5-6.5% by weight of styrene-butadiene rubber (SBR), 0.5-1.0% by weight of sodium lauryl sulfate, 10 to 14% by weight of FT wax, 2.5 to 3.5% by weight of attapulgite, 0.5 to 1.0% by weight of polybutene, dimethylaminopyridine (DMAP) dissolved in toluene, 2.5-4.5% by weight, and the balance of polychloroprene.

The styrene-butadiene-styrene (SBS) is a block-shaped polymer having a polystyrene moiety attached to the central polybutadiene moiety. The SBS polymer chain absorbs stress due to vertical load or horizontal load, And acts as an elastic body such as a spring to enhance elastic restoring force. However, when it is more than 4.5% by weight, the elasticity is improved, but the moldability is deteriorated. When it is less than 2.5% by weight, it is difficult to obtain the desired elasticity. The above-mentioned SBR (Styrene-Butadiene Rubber) is a synthetic rubbery rubber material composed of styrene and butadiene, and has good adhesion, abrasion resistance and aging stability. Typical examples are latex. These SBRs increase the softening point, increase the elongation and increase the viscosity at high temperature to enhance the heat resistance, but they may be problematic due to bubbles when formulated in an emulsion state. Therefore, the SBR must be added together with the defoaming agent sodium lauryl sulfate . However, since the defoaming agent may deteriorate the dispersibility of the composition when it is added in an excessive amount, a small amount of the defoaming agent should be added within the above range so that only the sphericity of the SBR can be maintained. The FT wax should be specified to have a molecular weight of 2,000-5,500 Da, a viscosity of 350 CP-800 CP of 130 ° C and a density of 0.9-0.95 in order to ensure sufficient elasticity even at low temperatures of the cushion member 230 , And should be limited to the above range so as not to weaken the temperature reversible cross-linking of the SBS molecules to lower the elastic force. In addition, the attapulgite is added in order to enhance heat resistance and elasticity as a fibrous phase. If it exceeds 3.5% by weight, the agglomeration is deteriorated. If it is added at less than 2.5% by weight, heat resistance and strengthening of elasticity are inhibited. . In addition, the polybutene is added to enhance resistance to ultraviolet light resistance and resistance to discoloration, and is limited to the above range because it is toxic. In addition, DMAP (dimethylaminopyridine) dissolved in toluene is added to the above range in order to promote the curing reaction while suppressing the high thermal expansion and to enhance the binding property between the compositions.

In this case, the bra cup used in the present invention can be realized to have desired heat resistance and elastic restoring force without using the conventional EPDM.

While the present invention has been particularly shown and described with reference to specific embodiments thereof, it will be understood by those of ordinary skill in the art that various changes in form and details may be made therein without departing from the spirit and scope of the invention as defined by the appended claims. Anyone who can afford it will know.
