Conventionally, as shown in Japanese Patent Application Laid-Open No. 2000-204320, phosphorescent pigments each composed of a phosphorescent material and a phosphite phosphor that emits visible light by excitation light other than visible light are known. ing.

【0003】

The phosphorescent material is, for example, an alkaline earth aluminate as a parent crystal, europium (Eu) as an activator, and dysprosium (Dy) or nedymium (Nd) as shown in Japanese Patent No. 2543825. It refers to an activator, and for example, N luminous (Lumi Nova) (trademark, manufactured by Nemoto & Co., Ltd.) is used. Further, the above-mentioned fluorinite is invisible under normal sunlight or fluorescent light, but is visible light due to the excitation light of one or both of 254 nm (2537A = UV short wave) and 365 nm (3650A = UV long wave). There are various emission colors such as green, blue, yellow, orange, and red. For example, SPE-A type (Sr)₃(PO₄)₃Cl: Eu), HG type (Zn)₂GeO₄: Mn), YS-A type (Y₂O₂S: Eu) can be used, and the body color is white in both cases.

【0004】

This SPE-A type emits blue light with a peak wavelength of 445 nm and has an average particle size of 1.5 ± 0.5 μm. The HG type emits green light with a peak wavelength of 534 nm and has an average particle size of 3.0 ± 0.5 μm. The YS-A type emits red light with a peak wavelength of 624 nm and has an average particle size of 2.2 ± 0.3 μm.

【0005】

Therefore, the inventor paid attention to such a phosphorescent pigment, and by adhering the phosphorescent pigment to the raw yarn, it emits light in various colors even in the dark such as at night, and the novelty of the design, visibility, etc. are improved. He devised the creation of a thread product that can be expected.

[Problems to be Solved by the Invention]

However, when adhering the phosphorescent pigment to the raw yarn, an attempt was made to attach a mixture of the phosphorescent pigment and the paste to the yarn by immersion, but the phosphorescent pigment cracked and peeled off from the yarn. As a result, the commercial value may be reduced due to uneven adhesion of the pigment, and the unevenness of the phosphorescent pigment may become a catching factor in the process of weaving, knitting, etc., which makes the roller transfer of the yarn unsmooth, resulting in extremely high production efficiency. It has the inconvenience that it may decrease.

BEST MODE FOR CARRYING OUT THE INVENTION

1 to 4 show examples of embodiments of the present invention, FIGS. 1 to 3 are examples of the first embodiment, and FIG. 4 is an example of the second embodiment.

【0013】

1 to 3 are examples of the first form, in which R is a raw yarn, and as the raw yarn R, threads and yarn bundles of various materials such as natural materials, synthetic fiber materials, composite materials, and recycled materials are used. , Various thread thicknesses are used.

【0014】

Reference numeral 1 denotes a pigment adhering portion. In this case, an adhering portion 1d composed of a dipping bath 1b and a sizing roll 1c is arranged in the painting chamber 1a, and visible light is provided in the dipping bath 1b by excitation light other than phosphorescent material and visible light. Luminescent pigment H that emits light with a different color from the color developed independently of each of the phosphorescent bodies that emit light.₁And glue H₂The compound H is housed in the above-mentioned material, and the yarn R sent from the yarn roll 1e is brought into contact with the outer peripheral surface of the sizing roll 1c so that the formulation H is attached to the yarn R.

【0015】

This phosphorescent pigment H₁And glue H₂Luminescent pigment 30% by weight to 50% by weight: Paste 50% by weight to 70% by weight is selected, and if the phosphorescent pigment is 30% by weight or less, the degree of luminescence becomes weak and 50% by weight. If it is more than the above, the degree of luminescence becomes strong but the cost becomes high. If the amount of the glue is 50% by weight or less, the adhesive performance becomes low, and if it is 70% by weight or more, the adhesive performance is sufficient but the degree of luminescence is weak. According to experiments, 40% by weight of phosphorescent pigment: 60% by weight of glue is desirable.

【0016】

Reference numeral 2 denotes a pre-drying portion, in which case the inside of the drawing chamber 1a is maintained at a predetermined low temperature, for example, a low temperature of 40 ° C to 60 ° C, and the inside of the drawing chamber 1a is maintained, for example, 100 M / min to 200 M /. The yarn is transferred at a thread transfer rate of min for 1 to 2 minutes using a guide roll 1f, and is wound on a winding roll such as a skein while being dried in the middle of the thread transfer path.

【0017】

When this pre-drying temperature is 40 ° C or less, the pre-drying is not sufficient, and the yarns parallel to each other by winding adhere to each other at the compound H, and the yarns are easily peeled off due to the unwinding of the yarns. This is because if it is C or more, the compound H may be excessively adhered and may be separated from the raw yarn R due to bending during winding or roller transfer. The yarn transfer speed and transfer time are selected according to the type and thickness of the yarn, but as a result of experiments, it has been found that they are almost the same under the above conditions.

【0018】

Reference numeral 3 denotes a main drying section. In this case, the inside of the drying chamber 3a is maintained at a predetermined high temperature, for example, a high temperature of 100 ° C to 120 ° C, and the inside of the drying chamber 3a is mixed by the pre-drying section 2. It is configured so that 1 g of a wound roll of the wound yarn R to which the object H is attached and pre-dried is left for a drying time of 60 to 90 minutes for main drying.

【0019】

When the main drying temperature is 100 ° C or less, the main drying is not sufficient and the parallel threads adhere to each other at the compound H, and the compound H is likely to peel off due to the feeding of the threads, and at 120 ° C or more. This is because the compound H may be excessively adhered and peeled from the raw yarn R in the weaving process or the like.

【0020】

Since the first embodiment of this embodiment has the above configuration, first, in the pigment adhesion portion 1, each of the raw yarn R is composed of a phosphorescent material and a fluorescent phosphor that emits visible light by excitation light other than visible light. Phosphorescent pigment H that emits light in a color different from that of the color₁And glue H₂The pigment adhering step A for adhering the compounding H to the above is performed, and then the pre-drying step B is performed in the pre-drying unit 2 to dry the raw yarn R to which the compounding H is adhered at a predetermined low temperature. Next, the main drying step C of drying the pre-dried raw yarn at a predetermined high temperature is performed, and the light yarn F is manufactured.

【0021】

Then, a yarn product made of a woven fabric, a knitted fabric, or the like is manufactured from the light yarn produced in this manner.

【0022】

In this way, the phosphorescent pigment H, which is composed of a phosphorescent material and a phosphite body that emits visible light by excitation light other than visible light, emits light in a color different from that of each of the raw yarn R alone.₁And glue H₂The pre-dried yarn R is first dried at a predetermined low temperature, and then the pre-dried yarn R is dried at a predetermined high temperature and phosphorescent. Sex pigment H₁And glue H₂Since the compound H of and is adhered to the raw yarn R, peeling and cracking of the compound H caused by bending of the yarn by a guide roll or the like during thread transfer are suppressed as compared with the case of drying once. It is possible to prevent the commercial value of the yarn product from being lowered due to uneven adhesion of the pigment, and the unevenness of the phosphorescent pigment becomes a catching factor in the process of weaving, knitting, etc., and the roller transfer of the yarn becomes unsmooth. It is possible to avoid the above, increase the production efficiency, and obtain a good yarn product.

【0023】

In this case, the pre-drying section 2 and the main drying section 3 have a parallel structure, and the raw yarn R is continuously transferred to continuously perform the pre-drying and the main drying. It is configured to go and wind up.

【0024】

Even in this second form example, the same action and effect as in the first form example can be obtained.

【0025】

The present invention is not limited to the above-described embodiment, and the type and thickness of the raw yarn, the phosphorescent material, the phosphorescent body, the type of the phosphorescent pigment, the blending ratio of the phosphorescent pigment and the above-mentioned paste, The pre-drying temperature and the main drying temperature are appropriately changed and designed.
