Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a luminescent clothing that is colored with a luminescent pigment.

[0002]

[Prior art and its problems]

 In general, attempts have been made to color clothing with coloring species called luminous pigments or luminescent pigments for a long time. This is intended to be applied to danger prevention clothes in the dark by utilizing the property that these colored species emit light to some extent in the dark, but it is generally known to have the following drawbacks. .

That is, when a phosphorescent pigment mainly composed of zinc sulfide and activated by various metals such as copper is used, the emission time thereof is extremely short at about 5 minutes at the longest, so that this kind of clothing is required. From the perspective of ensuring safety, it is hard to say that it is sufficient. On the other hand, it is known to add radioactive substances to prolong the emission time, but considering the effects on the human body, it is best to avoid adding such substances to clothing.

[0004]

[Problems to be solved by the device]

 An object of the present invention is to solve these problems of the prior art and to provide a luminescent clothing that can emit light for a long time without adversely affecting the human body.

[0005]

[Means for Solving the Problems]

 The above object of the present invention is achieved by a luminescent clothing whose entire surface is colored with a luminescent pigment which is substantially free of radioactive substances. “Substantially free of radioactive substances” refers to the case where no radioactive substances are contained at all, or when the radioactive substances are contained in a very small amount without adversely affecting the human body. The particle size of the luminescent pigment is preferably 1 μm to 50 μm. Examples of such a luminescent pigment include ceramics obtained by mixing and sintering high-purity alumina and a rare earth element, and specifically, “N luminescent” manufactured by Nemoto Special Chemical Co., Ltd. First name, but not limited thereto.

[0006] This type of luminescent pigment has hitherto been applied to a coating material within a very limited range such as a dial of a timepiece, but an example of applying it to fibers has not yet been reported. . However, studies by the present inventor have found that this type of luminescent pigment has an affinity for fibers, and in particular, when pigment particles having a particle size in the range of 1 μm to 50 μm are used. It has been found that the fibers can be colored to the extent that they have an excellent fastness. Therefore, the present invention is a completely new one, and the invention is inventive in that this kind of luminous pigment is selected from among many luminous substances.

Therefore, as a method of coloring the entire surface of the clothing in the present invention, a conventionally known padding method or dip dyeing method can be adopted. In this case, it is desirable to pretreat the clothing to be colored with a nitrogen-cationic compound in order to further improve the affinity for this type of luminescent pigment. Such nitrogen-cationic compounds include quaternary ammonium salt-type or pyridinium-salt-type cationic surfactants, and nitrogen-cationic polymers generally called polyamine-type, polycation-type, or dicyandiamide-type, and various types of nitrogen-cationic compounds. Examples thereof include cationic binders. On the other hand, it was also found that, even without such a treatment with a cationic compound, a fairly robust coloring can be obtained with this kind of luminescent pigment. Therefore, by omitting the treatment with the cationic compound, the manufacturing cost can be significantly reduced in terms of the treatment agent and the treatment process.

In addition to the coloring treatment with the above-described luminescent pigment, the clothing in the present invention may be treated with general dye pigments, thermochromic materials and photochromic materials, and other coloring agents such as glass beads and metal powder. It is also possible to treat the garments, and it is also possible to treat garments previously colored with these colorants with this type of luminescent pigment.

In addition, various agents used for treating ordinary clothes can be used. Examples of such agents include optical brighteners, ultraviolet absorbers, antioxidants, softeners, preservatives, flame retardants, fragrances, deodorants, repellents, insect repellents, antistatic agents, body pigments, Examples include white pigments and various binders.

In particular, treatment with various binders is preferable because the fastness to rubbing and the fastness to washing of the luminescent pigment on shirts are further improved.

In addition, the garment according to the present invention can be applied not only after the above-described respective treatments after sewing, but also at the time of the raw material such as a woven fabric, a knitted fabric or a non-woven fabric before sewing.

Examples of clothing used in the present invention include T-shirts, sweatshirts, sports shirts, polo shirts, waistcoats, work clothes, Henry neck shirts, boat neck shirts, V-neck shirts, high neck shirts, turtleneck shirts and chai. Examples include Naneck shirts, shirts and open shirts.

When applied to these clothes, compared to other clothing products, the colored area can be made relatively large, and in combination with being worn on the upper body of the human body, an effective visual effect can be obtained. Is advantageous in that However, if it is possible to obtain a sufficient visual effect, it can be applied to various other clothes such as suds, skirts and pantyhose.

As fiber types constituting these clothes, natural cellulose fibers such as cotton and hemp, natural protein fibers such as silk and wool, regenerated and semi-synthetic fibers such as rayon and acetate, acrylic, nylon and polyester. Examples thereof include various types such as synthetic fibers such as polyolefin and the like, and the present invention is not particularly limited to these, and these may be used alone or in combination of two or more kinds.

【Example】

 Hereinafter, embodiments of the present invention will be described.

Example 1 A scoured cotton T-shirt (100 parts by weight) was put into a drum dyeing machine having a capacity of 3000 parts by weight, and then 2000 parts by weight of water (bath ratio 1:20) was put in the dyeing machine. It was operated at 30 rpm. Next, 3% by weight of a nitrogen cationic compound (trade name: Fixer P; manufactured by Matsui Pigment Chemicals Co., Ltd.) with respect to the weight of the dough and 10% by weight of ethylene glycol with respect to the weight of the dough were preliminarily diluted with water 10 times The cotton T-shirt was cationized by diluting it in water and adding the aqueous solution from the chemical input port of the dyeing machine described above to gradually raise the liquid temperature and treating at 70 ° C. for 15 minutes. The cotton T-shirt was then rinsed thoroughly with water to remove excess nitrogen-cationic compounds and other additives and dehydrated. Next, the rotation was once stopped, 2000 parts by weight of water was added again to the dyeing machine, and the dyeing machine was operated at 30 rpm. Then, 10% by weight of the fabric weight of the luminescent pigment (trade name: N luminescent (Non-luminescent material containing no radioactive substance and having a particle size of 15 μm to 20 μm) manufactured by Nemoto Special Chemical Co., Ltd.) and the fabric weight 15% by weight of a binder (trade name: Matsuminzol MRconc (acrylic acid ester copolymer emulsion; manufactured by Matsui Dye & Chemical Co., Ltd.)) was diluted 10 times with water, and a dispersion liquid was charged from a chemical charging port. The liquid temperature was gradually raised and the cotton T-shirt was treated at 80 ° C. for 15 minutes. Subsequently, this cotton T-shirt was thoroughly rinsed, dehydrated, and then dried by a tumbler dryer at 90 ° C. for 2 hours.

The T-shirt thus obtained has good feel, feel, abrasion resistance, and washing resistance, and when left in a bright room in the dark, it emits bright light even after 2 hours. It lasted and had excellent visibility. Therefore, it was found that when the T-shirt manufactured according to this example is worn at night jogging, the T-shirt can be sufficiently seen from a distance and can have a particular effect as a danger prevention garment such as a traffic accident.

Example 2 200 m (50 kg) of a 90 cm wide mixed-spun circular knit fabric consisting of 35% polyester and 65% cotton, which have been ground-dyed in pink in advance, was put into a jet dyeing machine having a capacity of 3000 liters, and a bath ratio of 1 was obtained. After adding water so that the dyeing ratio became 20, the dyeing machine was operated. Next, after diluting 5% by weight of the quaternary ammonium salt type nitrogen-cationic compound (trade name: Panfix NF, manufactured by Yushisha Fat & Oil Co., Ltd.) with 100 times the amount of water in advance, dyeing It was put in the machine and treated at room temperature for 15 minutes. Subsequently, the temperature was raised to 70 ° C., and the mixed spun circular knit was cationized by treating at that temperature for 15 minutes. Subsequently, the circular knitted fabric was subjected to cold rinsing twice for 3 minutes in the same dyeing machine to remove excess cationic compounds. After the circulation was once stopped, water was supplied to the dyeing machine so that the bath ratio was 1:20, and the circulation was restarted. Then, the same luminescent pigment used in Example 1 was prepared in an amount of 10% by weight based on the weight of the cloth, diluted with 100 times by weight of water in advance, and gradually charged into the dyeing machine, followed by treatment at room temperature for 20 minutes. Further, the temperature was gradually raised to 50 ° C. and treated for 15 minutes. Then, the colored mixed-spun circular knitted fabric was rinsed for 2 minutes in the same dyeing machine. After stopping the circulation again, water was supplied to this dyeing machine at a bath ratio of 1:15, and the circulation was restarted. Then, 8% by weight of the fabric weight of the polyurethane resin emulsion binder (trade name: Hydran HW 311; manufactured by Dainippon Ink and Chemicals, Inc.) was previously diluted with 20 times by weight of water, put into a dyeing machine and gradually heated, and then treated at 80 ° C. for 15 minutes. Then, the circular knit fabric was taken out from the dyeing machine, dehydrated using a centrifugal dehydrator, opened, and dried at 80 ° C to 100 ° C using a tumbler dryer. After that, the knitted fabric was cut and sewn, and the polo shirt obtained had good feel, feel, abrasion resistance, and wash resistance. It had a high-brightness pink color, continued to emit light, and had excellent visibility. Such a shirt not only has a nighttime hazard prevention effect, but is also extremely fashionable.

Example 3 Using a roll padder, pre-scoured cotton fabric (50 cm width × 300 m length), 100 parts of water, 8 parts of the same luminous pigment as in Example 1, 0.03 parts of phthalocyanine blue, acrylic acid Ratio of 15 parts of ester copolymer emulsion (trade name: Matsuminzor M Rconc; manufactured by Matsui Dye Chemical Industry Co., Ltd.) and 0.5 part of ethylene urea-based condensate (trade name: Fixer F; manufactured by Matsui Dye Chemical Industry Co., Ltd.) After immersing the cotton fabric in a pad bath prepared by blending with 1. and then removing water with a mangle so that the squeezing rate is 100%, a nonterminating machine is used at a temperature of 100 ° C to 120 ° C using a tentering machine. Dried. Further, using the same padder, dipping it in the same pad bath prepared by mixing 100 parts of water and 2 parts of a silicone type softener (trade name: Softener AQ; manufactured by Matsui Pigment Chemicals Co., Ltd.), Subsequently, the product was dehydrated with a mangle to a squeezing ratio of 80%, and then dried at a temperature of 100 to 120 ° C. using a tentering machine. When the cotton fabric thus obtained was cut and sewn to prepare work clothes, it was found that it had good feel, feel, abrasion resistance, and wash resistance, and that it emitted blue light in the dark. Such work clothes can be easily seen from a distance in the dark, and can exert a special effect as work clothes for road construction in which a traffic accident at night is a concern, or as a uniform for a guard man for nighttime security. It has been found.
