〈従来の技術〉
従来、合成樹脂粉末原料に蓄光顔料粉末を混入して製品
原料とし、これを常法で成形して発光合成樹脂製品とす
る技術は一般に知られている。<Prior Art> Conventionally, a technique is generally known in which a luminescent pigment powder is mixed into a synthetic resin powder raw material to form a product raw material, and this is molded by a conventional method to produce a luminescent synthetic resin product.
また、従来、繊維の中て空洞をもたせた中空の化学繊維

たものである。Furthermore, hollow chemical fibers having cavities inside the fibers have also been developed. This hollow fiber is lighter than it looks (,
It is known to have a good insulation effect and a pleasant feel, and is used in clothing, blankets, and futon cotton. Thus, conventional hollow fibers were developed for the above purpose.
〈発明が解決しようとする課題〉
発光製品の従来の技術は、樹脂粉末原料に蓄光顔料粉末
を適量混入（７この際、所望に応じて適量の酸化防止剤
も合わせて混入する）し、この顔料混入の原料で常法に
より成形し、製品としている。<Problems to be Solved by the Invention> The conventional technology for producing light-emitting products involves mixing an appropriate amount of phosphorescent pigment powder into a raw material of resin powder (7. At this time, an appropriate amount of antioxidant is also mixed in as desired). The product is molded using conventional methods using raw materials mixed with pigments.
この製品は発光性を有しているが、次のような点におい
て改良し得る点を有している。Although this product has luminescent properties, it has the following points that could be improved.
即ち、上記従来品は、外部から光を照射すると、この光
を蓄えて発光するが、これは、専ら製品中の蓄光顔料の
作用だゆで光るものである。したがって、従来技術のも
のは発光度が比較的小となる問題点を有している。That is, when the above-mentioned conventional product is irradiated with light from the outside, it stores this light and emits light, but this glow is due solely to the action of the phosphorescent pigment in the product. Therefore, the prior art has a problem in that the luminous intensity is relatively low.
ところで、発光度の大小は製品原料中における蓄光顔料
の含有率により変えられるようにも思える。しかし、蓄
光顔料の混入料を多くしても、これにより高め得る発光
度には限度があり、また、原料中の顔料の比率が多すぎ
ると、樹脂製品の品質を低下させる問題点が生じる。By the way, it seems that the magnitude of luminescence can be changed depending on the content of luminous pigment in the product raw material. However, even if the amount of phosphorescent pigment added is increased, there is a limit to the amount of luminescence that can be increased, and if the ratio of pigment in the raw material is too high, the quality of the resin product will be degraded.
本発明は上記のような点に鑑みてなされたものであり、
その目的とするところは、製品原料中に含まれる蓄光顔
料の比率を変えることなく、発光度を大巾に高めること
ができろ発光繊維を提供しようとするものである。The present invention has been made in view of the above points,
The objective is to provide a luminescent fiber that can greatly increase luminescence intensity without changing the ratio of luminescent pigments contained in the product raw materials.
〈課題を解決する１こめの手段〉
本発明は、繊維の中に空洞をもたせて中空にすることに
より、非中空のものと比較して発光度が大巾に増大する
ことを見出し、発明を完成するに到ったものである。<First Means for Solving the Problem> The present invention has been made based on the discovery that by making fibers hollow by making them hollow, the luminous intensity is greatly increased compared to non-hollow fibers. It has come to completion.
即ち、本願の２・１の発明は、軸線方向に向けて空洞を
もたせた中空の化学繊維であって、上記化学繊維は所望

常法により成形されてし・ろことを特徴とするものであ
る。That is, the invention of 2.1 of the present application is a hollow chemical fiber having a cavity in the axial direction, and the chemical fiber is usually a product raw material made by mixing an appropriate amount of phosphorescent pigment into a desired basic raw material. It is characterized by a cylindrical shape formed by a method.
本願の牙２の発明は、上記矛１の発明において、製品原

入して成ることを特徴とするものである。The invention of Fang 2 of the present application is characterized in that, in the invention of Fang 1, the product raw material is made by mixing an appropriate amount of luminous pigment and aluminum metal powder into the basic raw material.
く作 用〉
本発明の発光繊維に外部から光を照射すると、この光は
繊維に含有されている蓄光顔料に蓄えられて発光するが
、この光の輝は空洞部の作用によって増進されるので、
発光度は大巾に犬になる。Effect> When the luminescent fiber of the present invention is irradiated with light from the outside, this light is stored in the phosphorescent pigment contained in the fiber and emits light, but the brightness of this light is enhanced by the effect of the cavity. ,
Luminous intensity becomes a big dog.
このことは実験により偶然発見したものであるが、繊維
を中空に形成することにより発光度が増大するのは次の
ような理由によるものと考えられる。Although this was discovered by chance through an experiment, it is thought that the reason why the luminescence intensity increases by forming the fiber hollow is as follows.
即ち、蓄光顔料が発光すると、この光は空洞部内で屈折
等の作用を受けて乱反射し、これが発光度の増進の原因
になるものと思慮する。That is, when the phosphorescent pigment emits light, this light is diffusely reflected due to effects such as refraction within the cavity, and this is considered to be the cause of the increase in luminous intensity.
また、Ｆ−２の発明にあっては、蓄光顔料から発光され
る光は繊維に含有されているアルミ系金属粉末によって
、さらに増進されろ。したがって、発光度は矛１の発明
のものより、さらに増大する。Furthermore, in the invention of F-2, the light emitted from the luminescent pigment is further enhanced by the aluminum-based metal powder contained in the fiber. Therefore, the luminous intensity is further increased compared to that of the invention of No. 1.
＝ ４
このことも実験てよって発見したものであるが、この発
光度の増進はアルミ系金属粉末ＶＣよって光が乱反射さ
れることに帰因するものと思われる。= 4 This was also discovered through experiments, and it seems that this increase in luminous intensity is attributable to the diffuse reflection of light by the aluminum metal powder VC.
