Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial field of application) The present invention relates to a beautifully colored uniform with a light colored portion that is durable and beautiful and is composed of dark and light colors.

(Prior Art) Conventionally, a polyester fiber uniform dyed with a disperse dye is generally worn.

(Problems to be solved by the invention) However, such a colored uniform has a serious discoloration due to washing or the like, and in a colored uniform having a white portion, the white portion is contaminated with the disperse dye that exudes from the colored portion. However, there is a drawback that it cannot be used as a uniform after washing. Such a contamination defect is particularly severe in the case of a waterproof cloth, which has a drawback that the commercial value is significantly reduced.

The present invention is characterized in that by applying a specific resin coating to a light-colored part such as white of such a colored uniform, the light-colored part is kept clean and the beautiful beauty of the light-dark part is durablely maintained. It was possible to provide a colored uniform.

(Means for Solving the Problem) The present invention takes the following means in order to achieve such an object. That is, a uniform consisting of a synthetic fiber cloth colored with a disperse dye and having a light-colored portion in a part thereof or sewn with a light-colored cloth, at least the fibers of the light-colored portion or the sewn portion are melamine-based. A colored uniform characterized by being coated with a resin coating. In such a uniform, the effect of the present invention is remarkably large when the cloth has a waterproof layer including a coating layer or a film layer.

The coloring uniform referred to in the present invention is, as shown in FIG.
A synthetic fiber cloth 1 colored in a relatively dark color with a disperse dye, which has a light-colored portion 2, that is, a line or a pattern colored in white, uncolored or light-colored,
The portion is covered with a melamine resin coating. The present invention is not limited to such colored products, and is also effective in a colored uniform in which a light-colored cloth having the coating is sewn to a cloth having the dark-colored portion.

Especially when the cloth is a colored uniform having a waterproof resin layer, the disperse dye has a property of fading more intensely,
Particularly excellent effects are exhibited in such a waterproof colored uniform.

The synthetic fiber in the present invention is a fiber that is dyed with a disperse dye, and is, for example, a fiber made of a polymer such as polyester or polyamide. In addition, it also includes composite fibers and blended fibers containing these polymers as sheath components. Furthermore, 1 of these polymers
Ultrafine fibers formed from sea-island type composite fibers or split type composite fibers, which are composed of two or more polymer components,
Even ultrafine fibers can be applied to the present invention.

Non-woven fabrics and knitted fabrics are included as such synthetic fiber fabrics.

Examples of the disperse dye in the present invention include azo type, anthraquinone type, nitrodiphenylamine type, methine type,
Examples include dyes such as aminoketone-based dyes.

The coloring with such a dye is preferably dyeing before forming the resin film. The dyeing method is not limited, and any of dip dyeing and textile printing (including discharge printing and anti-discharge printing) is effective. The coloring treatment with such a dye is preferably performed before the processing of the melamine resin.

In the present invention, usually, after forming a fabric, a melamine-based resin is processed to form a film. However, for fibers such as ultrafine fibers that require sea removal treatment, peeling, or division treatment, after the ultrafine fiberization process, Melamine resin is processed to form a film.

The melamine-based resin of the present invention is a compound containing a triazine ring and having at least two polymerizable functional groups,
That is, it is obtained by polymerizing the compound represented by the following general formula.

[In the formula, R _{0 to} R ₂ : hydrogen, a hydroxyl group, a phenyl group, an alkyl group having 1 to 10 carbon atoms, an alkyl ester (alkyl group = 1 to 20 carbon atoms), an amide group, an amino group (bonded to N The hydrogen is a hydroxyl group, an alkyl oxide group, a methyl alkyl ether group, a methyl alkyl ester group (alkyl group = 1 to 20 carbon atoms), a methylol group, an ethylol group, an N methylol amide group, an alkylene glycol with a degree of polymerization of 1 to 1500. Group <alkylene group = C _{2 to} C ₄ and terminal hydrogen thereof may be substituted with methyl, ethyl or propyl>)].

Among these, those in which R ₀ and R ₁ are amino groups are preferable, and those in which R ₂ is an amide group are more preferable.

Among these, those in which hydrogen bonded to N is substituted with a methylol group, an ethylol group, or an N-methylolamide group are preferable.

Further, R _{0 to} R ₂ are amino groups, and hydrogen bonded to N is an alcoholate group, a methylene alkyl ether group (alkyl group = 1 to 16 carbon atoms), a methylol group, an ethylol group, or N-methylol. The one substituted with an amide group has a feature that it can form a film sufficiently by leaving it in a wet state at room temperature, is suitable for energy saving measures, and has a film property excellent in flexibility. .

The present invention forms a coating film with such a melamine resin, and further comprises a dicyan derivative compound such as urea and thiourea, formalin, a phenol compound, a triazone compound, ethylene urea, a glyoxal compound and a uron compound. A polymerized product or a combination of these compounds can be used.

Such a melamine-based compound is applied as a treatment liquid in the form of a solution or dispersion containing an aqueous medium containing a polymerization catalyst.

The blending amount of the melamine compound in this treatment liquid is preferably 0.01 to 20% by weight, particularly preferably 0.1 to 1%.
It is in the range of 0% by weight. This blending range is selected from the viewpoint of coating strength and coarse hardness.

As the polymerization catalyst, acids such as inorganic acids and organic acids, and salts thereof are applied.

Examples of such inorganic acids include sulfuric acid, sulfurous acid, persulfuric acid, phosphoric acid, nitric acid, carbonic acid, hydrochloric acid and the like.

As the organic acid, a compound having a carboxyl group, for example, formic acid, aliphatic carboxylic acid such as acetic acid, acrylic acid,
Examples thereof include oxalic acid, malonic acid, malic acid, citric acid, tartaric acid, glutamic acid, aspartic acid, maleic acid, itaconic acid, phthalic acid, and isophthalic acid.

The amount of the catalyst added is 10 to 20% by weight (0.001 to 2% by weight in terms of solution) with respect to the usual amount of the catalyst, for example, the amount of the melamine compound compounded.

The composition comprising the melamine compound, that is, the treatment liquid is applied to the cloth by a method such as a dipping method, a spray method, or a coating method.

An important point as a heating condition for forming a film is to form the film in the presence of water.

That is, the temperature is room temperature, and further 40 ° C to 140 ° C.
Although a temperature range of a degree is applied, it is important that the polymerization reaction is carried out in an atmosphere having a fiber weight of 25% or more or a relative humidity of 40% or more. Of course, you may heat-react in the state immersed in a process liquid.

That is, it is important that the resin-forming component does not migrate on the fiber surface at the time of forming the film and is polymerized in a state of being held as it is, and the point in the film forming of the present invention is to impart the holding action to water.

Specifically, if the film is formed in a heating bath, the problem of migration does not occur, and good film formation can be achieved without problems. However, when the film formation is performed in a separate step, heating steam (saturation Or under unsaturated atmosphere (30 seconds-18
Either 0 minutes) or a cold batch method in which the treatment liquid-immersed product is hermetically sealed and allowed to stand without allowing water to escape (about one day and one night). can do.

The resin film thus obtained is not particularly limited, but is preferably 0.1% by weight or more, more preferably about 1 to 5% by weight, based on the weight of the fiber, in view of the migration and sublimation preventing property. It From the viewpoint of flexibility, it is preferable that the coating is uniform.

As the resin constituting the waterproof resin layer in the present invention, for example, polyurethane resin, vinyl chloride resin, polyacrylic resin, polyamide resin, silicone resin, fluorine resin, natural rubber or synthetic rubber, etc. The layer may be applied as a layer, but the layer is not limited thereto, and any resin that can exhibit waterproofness can be applied as the waterproof resin layer of the present invention. Among these resins, especially polyurethane-based resin is breathable and elastic,
It is preferably applied in terms of stretchability.

The waterproof resin layer is applied to the cloth by a coating method or a film laminating method.

At the time of coating, if necessary, an adhesive component, for example, an isocyanate compound whose end is blocked, is added in a required amount (for example, 0.1 to 10% by weight) to the coating liquid to improve the adhesion of the coating film to the cloth.

In the film laminate, an adhesive can be used if necessary, and as such an adhesive, a polyurethane adhesive, a polyacrylic adhesive, a polyester adhesive, a polyamide adhesive, a synthetic rubber adhesive can be used. And so on.

Among these, polyurethane adhesives are preferably applied from the viewpoints of adhesiveness, flexibility, stretchability, and the like. Such an adhesive is applied by a method such as whole surface application or intermittent application (dot application, spray application).

(Effects of the Invention) The present invention provides a colored uniform which is excellent in durability of the beauty of Tokiwa, in which the sharpness of a pattern having a relatively dark colored portion and a light colored line or a light colored portion is retained.
