No. 226 discloses a method of creating a composite image by irradiating visible light and ultraviolet light. This method involves dispersing a red, green, or blue inorganic phosphor in a coloring agent and using it as an ink or paint, and does not involve kneading it into fibers. Regarding the incorporation into ia, for example, JP-A-49-47646, JP-A-51-142043, JP-A-51-8
These are disclosed in Publication No. 6553, etc., but these are phosphorescent,
It is for fluorescent whitening and does not emit various fluorescent colors from blue to red under ultraviolet irradiation. Furthermore, regarding the fluorescence emission of fibers, organic fluorescent pigments are disclosed in Japanese Patent Application Laid-Open No. 60-21975, but since the ingredients are organic compounds, the luminescence life is short, and furthermore, they are sensitive to both visible light and ultraviolet light. The colors under irradiation are similar colors.

繊維の製造方法を提供するものである。That is, the present invention provides fibers that, when an inorganic fluorescent pigment is kneaded into a spinning dope and spun, and the formed yarn is irradiated with ultraviolet rays in a dark environment, a fluorescent color different from that under visible light is obtained. The present invention provides a method for manufacturing.
以下、本発明の詳細な説明する。The present invention will be explained in detail below.

料の色彩に復する。The yarn is made by incorporating an inorganic fluorescent pigment into the spinning solution.
Under visible light, it is almost white, but when exposed to ultraviolet rays in a dark environment, due to the oxidation of inorganic fluorescent pigments, it instantly emits fluorescent colors such as red, green, and evening blue. The fluorescent color disappears instantly. In addition, the yarn obtained by simultaneously kneading organic pigments or inorganic pigments and inorganic fluorescent pigments used in ordinary dope dyeing into the spinning dope and spinning them will not be as visible under visible light as the usual dope dye pigments. It emits color, but when exposed to ultraviolet rays in a dark environment, it instantly emits a different fluorescent color, and when the ultraviolet irradiation is stopped, the fluorescent color instantly disappears and the color returns to that of normal undiluted dyes and pigments. Furthermore, when yarn obtained by kneading an inorganic fluorescent pigment into a spinning stock solution and spinning the yarn is dyed using a normal method, under visible light it emits the color of the dye used for dyeing, but in a dark environment. When irradiated with ultraviolet light, a different color of fluorescent light is instantaneously emitted, and when the ultraviolet light irradiation is stopped, the fluorescent color instantly disappears and the color returns to that of the dye.

由に色彩を調節することができる。When one of these R fluorescent pigments, G fluorescent pigments, or B fluorescent pigments is kneaded into the spinning dope and the resulting yarn is irradiated with ultraviolet rays, it instantly turns bright red or green. Alternatively, it emits blue fluorescent color, and by mixing two or more of these fluorescent pigments into the spinning dope, colors including white can be freely adjusted.
また、これらの無機螢光顔料は、耐光性、耐熱性が優れ

発して糸を損傷する。The particle size of the inorganic fluorescent pigment used in the present invention is from 0.5 to
The diameter is about 30μ, preferably about 1 to 10μ. One can be selected as appropriate depending on the use of the fiber or the nozzle hole diameter, but any nozzle hole diameter can be selected. It is desirable to use inorganic fluorescent pigments with the following particle sizes. If the particle size is less than 1 μm, the luminescence under ultraviolet irradiation will decrease, and if it is more than 30 μm, the luminescence will be good, but the nozzle will frequently clog during spinning, damaging the yarn.
無機螢光顔料を、ｇ！維に対して１〜３０重量襲、好ま
しくは５〜１５重ｉ％、紡糸原液に混合する。Inorganic fluorescent pigment, g! It is mixed into the spinning dope in an amount of 1 to 30% by weight, preferably 5 to 15% by weight, based on the fiber.

が多発するうえ、糸が脆くなる。If it is less than 1% by weight, the luminescence under ultraviolet irradiation will be markedly reduced, and if it is more than 30% by weight, nozzle clumping will occur frequently during spinning and the yarn will become brittle.
これらの無機螢光顔料は、粉末のまま紡糸原液に混合し

ましくは１５〜５０重量％含有されるように調製する。These inorganic fluorescent pigments may be mixed into the spinning dope as a powder, but it is easier to work with it if they are dispersed in water or a dispersion medium in which the fluorescent pigment is insoluble to form a pigment composition and then mixed into the spinning dope. In that case, the inorganic fluorescent pigment is preferably contained in an amount of 5 to 70% by weight, preferably 15 to 50% by weight.

類によって、分散助剤のイオン性を適宜１選択する必要
がある。Since the inorganic fluorescent pigment has a fine particle size of 1 to 30 μm, when mixed with the spinning dope, the inorganic fluorescent pigment particles will secondary aggregate in the spinning dope, causing the particles to form at the nozzle base or under ultraviolet irradiation. Since this may cause adverse effects such as a decrease in light emission, it is recommended to add a dispersion aid such as polyoxyethylene alkylamine ether or amino acid carboxylic acid sodium salt to the inorganic fluorescent pigment in an amount of 5 to 100% by weight based on the inorganic fluorescent pigment. , preferably 10-4
It is better to use a composition containing 0 weight i% of the additive. The ionicity of these dispersion aids may be nonionic, anionic, or cationic, but cationic dispersion aids may be used for those that interact with the spinning stock solution, such as viscose where the spinning stock solution is anionic. It is inappropriate to use such a dispersion aid, and the ionicity of the dispersion aid must be appropriately selected depending on the type of spinning dope.
このようにして調製した無機螢光顔料またはその組成物

After stirring with a stirrer for 15 to 60 minutes at high speed rotation of 00 to s, ooo times, spinning is performed.

It also has high fastness against friction and washing.

Drying was performed. Although the amount of inorganic fluorescent pigment added was adjusted to 10% by weight based on the rayon yarn, the spinning condition was good. When the obtained rayon thread is irradiated with ultraviolet rays in a dark place, it instantly takes on a purple fluorescent color, and when the rayon irradiation is stopped,
The color immediately disappeared and turned white. This rayon thread is 14
