Current high visibility warning clothing looks the most eye-catching generally by the daytime of the upper standard area of laminating or sewing
Fluorescent material and night have the clothing of the Counter-reflection membrane of strong reflecting effect, either daytime or night lights under light source irradiates
Irradiate the lower existence that can visually highlight wearer, other people are played warning function, it is to avoid accident occurs.
But, phosphor layer is set at clothing surface and can directly affect the sense of touch of clothing surface and the breathability of clothing, repeatedly
The phosphor layer of washing rear surface the most easily drops, and the fluorescence area being arranged such is limited, the most obvious.Manage the most
The method thought is to use fluorescent dye direct printing to fabric, and fluorescent dye is to absorb and strong in visible region according to dyestuff
Strong transmitting light also launches the characteristic of fluorescence and the dyestuff named, and cationic fluorescent dyestuff is the one wherein commonly used.Bafta by
In comfortable and easy to wear, very popular, but bafta itself can not be well by fluorescent dyeing, even if first advancing
Row modification, the color fastness of dyeing gained fabric and uniform coloring, and fluorescence persistence etc. are the most not ideal enough.
Summary of the invention
It is an object of the invention to as overcoming above-mentioned the deficiencies in the prior art, it is provided that the production technology of a kind of fluorescence bafta.

The development of PECH-amine, Yu Yinan, remaining water woods, textile journal: 2001,22,3,138-140.
Preferably, sonic oscillation 2～3 hours after step (3) stirring and evenly mixing.
Preferably, the water-soluble fluorescent dye in step (3) is cationic fluorescent dyestuff, such as dye of positive ion fluorescein
X-10GFF300%.
Preferably, after step (4) is dried, continue under the conditions of 200 DEG C, dry moisture content≤1.5% to product, exist afterwards
Temperature 150 DEG C, pressure 3kg/cm2Under the conditions of fixation treatment 40 minutes.
Beneficial effects of the present invention:
The fluorescence bafta of the present invention both can be as everyday general purpose, to meet the requirement of fashion, again can as required with
The 3M reflectorized material etc. bought on meaning collocation market, thus make the high visibility warning clothing that can use evening, its fluorescence
Performance meets the requirement of relevant criterion.
The mode that bafta is used stagewise to heat up by the present invention is modified processing, after modification, and warm water soaking one
Dye again after the section time, be also adopted by stagewise during dyeing and heat up, be effectively improved the dye-uptake of bafta.Fluorescent dye slowly adds
Enter, to ensure that it slowly and uniformly spreads in sodium carboxymethyl cellulose solution, it is ensured that fluorescent dye and carboxymethyl cellulose
Element sodium is sufficiently mixed, and utilizes thickening and the cementation of sodium carboxymethyl cellulose, thus ensure gained mixing uniformity and on
Color uniformity and color fastness, absorption firmly, is not affected by conventional wash, still has well after cyclic washing and long-time dress
Fluorescent effect.
Gained fluorescence bafta of the present invention still remains the feature of original bafta, has good hygroscopicity and breathability,
Soft, comfortable and easy to wear, there is excellent wearability.

Bafta color fastness index after embodiment 1～5 and comparative example 1～4 dyeing is tested, the results are shown in Table 1.
Table 1. color fastness test result
As it can be seen from table 1 gained bafta of the present invention has significantly higher color fastness.
Observing embodiment 1～5 and the dyeing uniformity of comparative example 1～4 bafta under natural light, embodiment 1～5 dyes
Uniformly, comparative example 1～4 substantially has deep mixed color lump.
China and European Commission promulgate and have updated GB 20653:2006 and BS EN ISO 20471:2013 in succession, high with specification
The quality safety of visual warning clothing, it is shown in Table 2 to the chromaticity requirements of fluorescent material, the chromaticity coordinate (x, y) of fluorescent material
Requiring in the chroma areas of table 2, luminance factor β requires not less than minima β in table 2min。
The colorimetric parameter requirement of fluorescent material in table 2. standard
X, y:CIE1931 (x, chromaticity coordinate value y).International lighting association (CIE) is according to the vision of standard Observer
Experiment, radiates human eye the in addition record of the visual impression caused by energy, calculates Red Green Blue different wave length
Color matching function, according to this color matching function, represents human eye with X, Y, Z the stimulus value of visible ray.CIE1931 (x, y)
Chromaticity coordinate value X, Y, Z are converted into x, y chromaticity coordinate, x=X/ (X+Y+Z), y=Y/ (X+Y+Z).
β: luminance factor, refers under equal illumination and observation condition, and the brightness of specimen surface is bright with standard white plate of diffuse reflectance
The ratio of degree.
Bafta after embodiment 1～5 and comparative example 1～4 dyeing is carried out colorimetric detection, the results are shown in Table 3.
Table 3. embodiment 1～5 and the colourity of comparative example 1～4 compare
| x | y | β | |
| Embodiment 1 | 0.413 | 0.540 | 0.94 |
| Embodiment 2 | 0.400 | 0.499 | 0.95 |

| Comparative example 4 | 0.390 | 0.235 | 0.22 |
From table 3 it can be seen that the bafta of embodiment 1～5 fluorescence staining, chromaticity coordinate (x, y) falls in the colourity of table 1
In region, luminance factor β is far longer than minima β in table 1min；The bafta of comparative example 1～4 fluorescence staining, colourity
Coordinate (x, y) is all outside the chroma areas of table 1, and luminance factor β is less than minima β in table 1min, do not meet standard
Requirement.
By embodiment 1～5 and comparative example 1～4 wash 100 times respectively after and after using 2 years, re-start colourity inspection
Survey, found that the fluorescence color that contaminated of comparative example 1～4 almost takes off to the greatest extent, and the chromaticity index of embodiment 1～5 almost without
Change.Illustrate that the bafta of the present invention remains to keep preferable fluorescence property after scrubbed, do not affected by conventional wash,
Good fluorescent effect is still had after long-time use.
Although the above-mentioned detailed description of the invention to the present invention is described, but not limiting the scope of the invention,
On the basis of technical scheme, those skilled in the art need not pay the various amendments that creative work can be made
Or deformation is still within protection scope of the present invention.
