Abstract

PURPOSE:To prepare the subject soft cloth resistant to staining with hair dye by forming a surface skin resin layer and an adhesive layer having high adhesivity on a textile cloth and successively forming a water-repellent resin layer on the surface. CONSTITUTION:A textile cloth composed of synthetic fiber, etc., is preferably calendered and subjected to water-repelling treatment. A surface-skin resin layer composed of a soft acrylic resin or polyurethane resin having a 100% modulus of 5-60kg/cm<2> is applied to the treated cloth. An adhesive having high adhesivity to the resin layer is applied to the layer and dried. The dried product is successively coated with a resin layer such a as fluororesin or a fluorine- modified acrylic resin to obtain a stain-proof coated cloth for hairdyeing, resistant to cleaning, exhibiting stain-proofing performance to all kinds of hair dyes and colorable to enable the development of colors to improve the fashionability.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention has a very low level of contamination even when any hair dye such as oxidative hair dye, which is a permanent hair dye, and acidic hair dye, which is a semi-permanent hair dye, is attached to the hair dye. The present invention relates to an antifouling coating fabric for hair dyeing, which has antifouling properties against agents, has a soft texture, and has washing durability.

[0002]

2. Description of the Related Art A conventional hair dyeing cloth is produced by coating or laminating a flexible polyurethane resin, chlorosulfonated polyethylene resin, vinyl chloride resin, chloroprene rubber or the like on a woven or knitted fabric made of synthetic fibers. However, since no measures have been taken to prevent the hair dye from being contaminated, contamination of the fabric has been a serious problem.

For this reason, as a method for making the contamination less noticeable, a method of internally adding a black pigment to the coating resin layer or a method of dyeing the fibrous base material in black has been carried out. However, this method can only express black. However, there is a defect that the antifouling coating fabric for hair dyeing lacks fashionability. In addition, the conventional hair dyeing cloth is not sufficient as a hair dyeing cloth because the hair dye adheres to the skin and clothes due to the penetration of the hair dye into the cloth.

[0004]

DISCLOSURE OF THE INVENTION The present invention has very little contamination even when all hair dyes such as oxidative hair dyes which are permanent hair dyes and acidic hair dyes which are semi-permanent hair dyes are attached, An object of the present invention is to obtain an antifouling coating fabric for hair dyeing, which can be fashioned because it can be colored in a color other than black, has a soft texture, and has excellent wash durability without deteriorating the antifouling performance even by washing.

[0005]

In order to achieve the above object, the present invention provides a fiber cloth which has been subjected to a calendar treatment or a water repellent treatment as a resin permeation prevention treatment in advance to have a 100% modulus of 5 to 60 kg / cm. ² made of acrylic resin or urethane resin, an adhesive having good adhesive between the skin resin layer 5 to 100 g / m ² was applied, to the film formed by drying. After that, a fluorine resin or a fluorine-modified resin is applied as a dry film to a thickness of 3 to 50 μm and dried.

[0006]

[Function] When an oxidative hair dye is used, an alkaline agent (ammonia, monoethanolamine, triethanolamine, etc.) is used to diamine a diamine (aromatic amino compound such as paraphenylenediamine and a similar compound, toluene-2.5). -Diamine, N-phenylparaphenylenediamine, orthoaminophenol, metaaminophenol, etc.), toning agent (polyphenol such as resorcin, hydroquinone), excipient (surfactant, higher alcohol, wax, etc.), hair restorer・ Protective agent (polypeptide, silicone, glycol, etc.), stabilizer (sulfite,
Edetate), hydrogen peroxide, etc. permeate and polymerize inside the hair to develop color and dye hair.

In this case, since the fluorine or fluorine-modified resin film of the skin resin layer formed on the surface of the fabric is highly non-adhesive due to its surface energy, adhesion of a hair dye or the like is less likely to occur, and the crystals Since the hair dye has high properties, it is difficult for the hair dye to permeate.

Further, in the case of an acidic hair dye, an acidic dye permeates the hair quality with a penetrant (N-methylpyrrolidone, benzyl alcohol, etc.) to dye the hair. If a resin, chlorosulfonated polyethylene resin, chloroprene rubber or the like is used, these resins are easily swollen by the penetrant and contaminated by the acid dye. However, if fluorine resin or fluorine-modified resin is used as the skin resin layer,
Since the resin film has high non-wetting property and solvent resistance, the hair dye hardly accompanies swelling and an antifouling effect can be obtained.

Even when these oxidative hair dyes and acidic hair dyes adhere to the skin resin layer, the fluorine resin or fluorine-modified resin surface has a small critical interfacial tension and a large contact angle, so that the adhered matters are washed. Will be easily dropped.

The fluororesin used in the present invention is
Solvent-soluble fluoroolefin copolymer, copolymerization of fluoroolefins such as vinylidene fluoride, tetrafluoroethylene and hexafluoropropylene with ethylenically unsaturated compounds such as olefins, vinyl ethers and vinyl esters It is a thing.

The fluorine-modified resin is an acrylic resin,
A fluorine group such as a fluoro group or a perfluoroalkyl group is introduced into a side chain of urethane resin, silicon resin, epoxy resin or the like.
