DETAILED DESCRIPTION

[0018] In one aspect, the present invention provides a deodorizing and anti-irritating brassiere. The brassiere includes one or more fabric portions and the fabric portions are made of nylon, polyester, cotton, and polyurethane (e.g., Spandex); these include fabric blends of nylon, polyester, cotton, and polyurethane/Spandex. The brassiere has a deodorizing and anti-irritating coating that includes a deodorizing, bactericidal and fungicidal component of

##STR00009##

wherein m is 2, 3, 4, 5, 6, 7, 8, 9 and a deodorizing component that includes the following compound:

##STR00010##

and a cyclodextrin compound according to the following formula (I)

##STR00011##

wherein n is 6, 7, 8; R1, R2, and R3 are jointly or independently selected from H or

CH.sub.2CH.sub.2SO.sub.3.sup.Na.sup.+(II)

wherein the total number of groups represented by formula (II) can be 2, 4
wherein a ratio of

##STR00012##

is 0.7:1 to 1.6:1 by weight.

[0019] The deodorizing, bactericidal and fungicidal component of

##STR00013##

wherein m is 2 is 3- [(3-methacrylamidopropyl) dimethylammonio] propane-1-sulfonate and is capable to demonstrate excellent deodorizing, bactericidal and fungicidal properties. The positive charge of zwitterion shall be able to neutralize basic odorous molecules such as ammonia. The negative charge of zwitterion is able to neutralize acidic odorous molecules including isovaleric acid and methyl mercaptan via the sulfonate groups. In addition, the group exhibits bactericidal and fungicidal properties by allowing destruction of cell membranes via physical cell lysis or charge disruption of bacteria and fungi (cell lysis).

[0020] Formula (I) where n is 7 represents a beta-cyclodextrin. The functional groups of formula (II) that may be used as R.sub.1, R.sub.2, and/or R.sub.3 form sulfonated beta-cyclodextrin. Sulfonated beta-cyclodextrin is capable to neutralize odorous compounds with acidic moieties, such as isovaleric acid and methyl mercaptan. The hydrophobic cavity of cyclodextrin allows capturing of neutral VOCs, such as toluene and nonenal.

[0021] Use of cyclodextrins is advantageous as they may block pore-forming toxins and utilized as inhibitors of toxins and anti-infectives. In particular molecules having the same symmetry as the target pores are highly potent inhibitors.

[0022] As will be discussed in further detail below in the Examples, the coating layer may be provided to the brassieres through a simple dip-coating process. The dip coating solutions used to form the coating layer may include various additional components including, for example, crosslinkers, initiators, additives, and metal salts.

[0023] Co-polymerization of suitable components provides a deodorizing and anti-irritating coating when applied on fabric that is durable against home laundry, and is heat resistant during the brassiere pad lamination process. The deodorizing, bactericidal and fungicidal component of

##STR00014##

is 0.7:1 to 1.6:1 by weight enable co-polymerization to take place in water during the dip-coating process for the formation of the said coating when applied on fabric surface. Crosslinkers that comprise acrylamide groups further enable co-polymerization to take place in water during the dip-coating process for the formation of the said coating when applied on fabric surface. Examples of crosslinkers include one or more of N,N-methylenebismethacrylamide, N,N-methylenebismethacrylamide, N,N-methylenebisacrylamide, N,N-bis (2-acrylamidoethyl)acrylamide, N-[tris (3-acrylamidopropoxymethyl) methyl] acrylamide, N,N-[oxybis (2,1-ethanediyloxy-3,1-propanediyl)] bisacrylamide, N,N-1,2-ethanediylbis {n-[2-(acryloylamino) ethyl] acrylamide}, diethylene glycol dimethacrylate, diethylene glycol diacrylate, or one or more of the following compounds:

##STR00022##

where p is 4 to 14, or

##STR00023##

where q is 4 to 14.

[0024] The dip coating solution may further include one or more initiators. The initiator(s) are selected from compounds that can react with the acrylamide groups of the bactericidal and fungicidal component of component of

##STR00024##

wherein m is 2, 3, 4, 5, 6, 7, 8, 9 and the compound of deodorizing component:

##STR00025##

that is installed on the other compound according to the following formula (I)

##STR00026##

wherein n is 6, 7, 8; R1, R2, and R3 are jointly or independently selected from H or

CH.sub.2CH.sub.2SO.sub.3.sup.Na.sup.+(II)

wherein the total number of groups represented by formula (II) can be 2, 4 wherein a ratio of

##STR00027##

is 0.7:1 to 1.6:1 by weight
to enable co-polymerization to take place in water during the dip-coating process for the formation of the said coating when applied on fabric surface. The initiator(s) may be one or more of 2,2-azobis [2-(2-imidazolin-2-yl) propane] disulfate dihydrate, 2,2-azobis [2-(2-imidazolin-2-yl)propane] dihydrochloride, 2,2-azobis (2-methylpropionamidine) dihydrochloride, 2,2-azobis [2-(2-imidazolin-2-yl) propane], 2,2-azobis [n-(2-carboxyethyl)-2-methylpropionamidine] n-hydrate, 2,2-azobis [2-methyl-n-(2-hydroxyethyl)propionamide], or 4,4-azobis (4-cyanovaleric acid).

[0025] Additional additives may be present in the dip-coating solution to enhance rheological properties of the solution or to enhance adhesion to the fabric. Such additives include one or more of acrylic acid, 2-(dimethylamino) ethyl acrylate, 3-(trimethoxysilyl) propyl acrylate, glycidyl acrylate, methacrylic acid, 2-acrylamido-2-methylpropanesulfonic acid, N-[3-(dimethylamino)-propyl] acrylamide, N-[2-(dimethylamino)-ethyl] acrylamide, N-(3-dimethylaminopropyl)-methacrylamide.

[0026] The metal salts used in the dip coating solution may be one or more of zinc acrylate, sodium acrylate, potassium acrylate, zinc methacrylate, 2-acrylamido-2-methylpropanesulfonate sodium salt, and/or 3-sulfopropyl acrylate potassium salt. The metal salts may bind to the deodorizing, bactericidal and fungicidal component of

##STR00028##

wherein m is 2, 3, 4, 5, 6, 7, 8, 9
The bound metal ions are capable of inducing an oligodynamic effect on incoming bacteria at low concentrations. One mechanism involves the oxidation of metal ions; as the ions oxidize, they use electrons from bacterial cell membranes, destroying the membrane. Alternatively, uptake of metal ions in large quantities by bacteria create a toxic condition and the bacteria are killed.

[0027] It is noted that metal salts set forth above do not require the presence of silver. That is, the present invention provides a silver-free fabric treatment system; silver is not required to provide the bactericidal properties of the treated fabric.

[0028] The components of the solution described above may be easily applied to fabric by a dip-coating technique. The term dip-coat, as used herein, broadly relates to any technique in which a fabric is immersed in a solution with or without mechanical agitation during the dip-coating.

[0029] A variety of fabrics may use the fabric finish of the present invention. Such fabrics include, but are not limited to polyester-based fabrics, nylon-based fabrics, urethane-based fabrics (e.g., spandex), cotton-based fabrics.

[0030] The dip-coating may be performed at room temperature (defined as approximately 20-27 C.) or it may occur at an elevated temperature of 28-80 C. The duration of the dip-coating may range from approximately 5 to 60 minutes depending in part upon the weight and density of the fabric. Following dip-coating the fabric may optionally be washed with water, followed by drying/curing. Drying may be by air-drying or drying at elevated temperature. The drying time will depend upon the weight of the fabric but typically the time is about 5 to 60 minutes at a temperature of about 60 to 180 C.

[0031] A brassiere having the launderable bactericidal, deodorizing, and anti-irritation fabric finish prepared as described above has bactericidal activity of at least 90% in terms of reducing bacterial growth and activity from bacteria including one or more of Staphylococcus aureus, Klebsiella pneumonia, and has deodorizing performance of at least 90% including one of more of acetic acid, isovaleric acid and ammonia. Details of fabric testing against bacteria are set forth in the Examples, below. The coating weight of the fabric finish ranges from approximately 10.3 to approximately 70.9 g/m.sup.2.
