experiment example 1
[0030] Experimental Example 1: Preparation of Dispersion
[0031] The orange fluorescent pigment, titanium dioxide, dispersant, defoamer, and solvent were subjected to a grinding and dispersing procedure to form dispersion A and dispersion B, respectively. The weight ratio of fluorescent pigment and titanium dioxide is 4. The commercial model of the dispersant is BYK190, the commercial model of the defoamer is BASF-FoamStar ST 2410, and the solvent is water. Please refer to the following table 1 for the material dosage of the dispersion liquid.
[0032] Table I
[0033]
[0034] The crystal form of titanium dioxide in the dispersion B is rutile, and its X-ray diffraction (X-ray diffraction) spectrum please refer to figure 1 .
experiment example 2
[0035] Experimental Example 2: Analysis of Dispersion
[0036] After the dispersion liquid A and dispersion liquid B were placed at 65°C for 7 days, the average particle size, molecular weight distribution index (polydispersity index, PDI), D 10 、D 50 、D 90 , and Zeta potential for testing. The results obtained under the above conditions will be similar to the results obtained after the dispersion was left at room temperature for 30 days. Please refer to Table 2 below for the test results.
[0037] Table II
[0038]
[0039] It can be seen from Table 2 that after a long period of storage, the dispersibility of dispersion liquid A and dispersion liquid B are both good, and the molecular weight distribution of the composite pigment in dispersion liquid B is relatively uniform.

[0040] Experimental Example 3: Preparation of Fluorescent Fibers
[0041] In Examples 1-3, the dispersion liquid B, the fiber body, and the additives were stirred to obtain fluorescent fiber raw materials. The material of the fiber body is semi-gloss nylon 6. Additives include dispersants, antioxidants, and stabilizers. The dispersant is ethylene bis stearamide. The commercial model of the antioxidant is IRGANOX 1010. The commercial model of the stabilizer is IRGAFOS 168. The fluorescent fiber raw material is subjected to a drying procedure, followed by a kneading and granulation procedure to form a fluorescent fiber masterbatch, and then, a melt spinning procedure is performed on the fluorescent fiber masterbatch to form a fluorescent fiber. Please refer to the previous article for the experimental conditions, and will not repeat them here. The fluorescent fiber in this experimental example is a fully oriented yarn (FOY), and the fiber specification is about 70d / 72f. Pl...
