Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a stain removal tape for easily removing stains attached to clothes or the like.

[0002]

2. Description of the Related Art Conventionally, in order to remove stains on clothes or the like, a soft cloth or paper such as gauze or tissue paper is placed on the back side, and the front side is hit with benzine or gauze impregnated with a portable stain remover. As a result, dirt was transferred to the back side. For example, JP-A-4-57962 and JP-A-4-57963 disclose a novel stain removal composition comprising an alkylene glycol derivative, a surfactant and water in order to remove oily stains more cleanly. ing. When stains such as clothes are removed using this stain-removing composition, the composition is applied to stains, and the back side is brought into contact with gauze or the like and lightly tapped on the front side to transfer to the gauze or the like.

However, since stain components (colorants and resin components) dissolved in a solvent spread by hitting,
Even after the solvent was dried, the stain remained bleeding and it was difficult to completely remove the stain.

The stain removal tape of the present invention comprises a stain elution tape (A) and a stain absorption tape (B).

Stain-eluting tape (A) used in the present invention
Is one in which a plaster layer containing an adhesive, a solvent and a surfactant is formed on a support.

The pressure-sensitive adhesive used in the stain-eluting tape (A) is not particularly limited as long as it has adhesiveness to clothes and can be dissolved in a solvent described later, and examples thereof include natural rubber and styrene. A rubber-based pressure-sensitive adhesive containing an isoprene-styrene copolymer as a main component; an acrylic-based pressure-sensitive adhesive; a silicon-based pressure-sensitive adhesive can be used, but an acrylic-based pressure-sensitive adhesive is preferable from the viewpoint of stability.

Examples of the acrylic adhesive include (meth)
Acrylic ester (co) polymers are preferred. As a monomer constituting such a (meth) acrylic acid ester (co) polymer, a (meth) acrylic acid ester having an alkyl group having 1 to 18 carbon atoms is used. Examples of such a monomer include methyl (meth) acrylate,
Examples thereof include ethyl (meth) acrylate, butyl (meth) acrylate, 2-ethylhexyl (meth) acrylate, and dodecyl (meth) acrylate. These may be used alone or in combination of two or more.

The solvent used in the stain-eluting tape (A) is not particularly limited as long as it can dissolve the dyes and resins constituting the stain, and examples thereof include benzine, hexane and white gasoline.

The surface active agent used in the stain-eluting tape (A) is used for the purpose of supplementing the penetrating power into the fabric. For example, an anionic surface active agent, a cationic surface active agent,
Nonionic surfactants and amphoteric surfactants are preferably used.

Examples of the anionic surfactant include higher alcohol sulfuric acid ester, polyhydric alcohol fatty acid ester, polyoxyethylene alkyl ether sulfuric acid ester, polyoxyethylene alkylphenyl ether sulfuric acid ester salt, and the like. Examples of ionic surfactants include fatty acid amine salts and quaternary ammonium salts.

Examples of the nonionic surfactants include fatty acid esters of polyhydric alcohols and polyoxyethylene alkyl ethers, and examples of the amphoteric surfactants include aminocarboxylic acid type and imidazoline type surfactants. Surfactants may be mentioned.

The support used in the present invention is, for example, a plastic sheet having flexibility and good chemical resistance and solvent resistance, and the material is, for example, polyethylene or polypropylene. , Polyethylene terephthalate and the like.

Stain absorbing tape (B) used in the present invention
Is an adhesive layer formed on a support made of non-woven fabric.

As the non-woven fabric used for the above support,
Examples thereof include those made of polyethylene, polypropylene, polyethylene terephthalate, etc., which have good chemical resistance and solvent resistance.

As the pressure-sensitive adhesive used in the pressure-sensitive adhesive layer of the stain-absorbing tape (B), the same pressure-sensitive adhesive as that used in the stain-eluting tape (A) is preferably used.

The stain-eluting tape (A) is prepared, for example, by applying a solution in which a pressure-sensitive adhesive, a solvent and a surfactant are uniformly mixed onto a support and drying the solution to form a plaster layer, and then to a predetermined size. It can be obtained by cutting into. If necessary, an adhesive solution such as ethyl acetate may be added to the above solution.

The stain-absorbing tape (B) may be prepared, for example, by adding a pressure sensitive adhesive solution such as ethyl acetate to the pressure sensitive adhesive, heating and dissolving it, and then applying it on a non-woven fabric and drying it. It can be obtained by forming an agent layer and cutting it into a predetermined size.

In the case of removing stains using the stain removing tape of the present invention, first, the plaster layer of the stain elution tape (A) is pressed against the surface of the stain-attached garment to be adhered,
Then, the stain absorbing tape (B) is attached to the back surface of the garment, and the stain adhering to the garment is absorbed by the stain absorbing tape (B) side, whereby the stain can be easily and cleanly removed.
