(1) The same fluorescent coating, using different adhesives, has different fluorescence levels. Currently, the commonly used (F) Dongfeng brand adhesives and Michelin adhesives have been obtained
The fluorescence obtained is bright and bright, and the use of Michelin adhesive also has a softer hand feel.
(2) Fluorescent coating color matching has less influence from adjacent spectra, otherwise it will affect the fluorescence level, and in severe cases, it may even cause the disappearance of fluorescence. For example, when color matching with general coatings, the fluorescence level will also decrease.
(3) When printing, the amount of coating used increases, and the fluorescence also increases, otherwise it decreases. However, when the dosage is generally around 30%, the effect of increasing the dosage is not significant due to the improvement rate of the coating.
(4) The tighter, whiter, and smoother the printed fabric, the brighter it will be when printed with fluorescent coating; Conversely, it is worse. So printing smooth white poplin and horizontal satin has a better fluorescent effect
Okay; And when printed on velvet, the fluorescence is affected.
(5) The arrangement of flower tubes also has a significant impact on fluorescence, pressing an extra flower tube will reduce some fluorescence. Therefore, from the perspective of fluorescence, it is better to rank later (but attention should be paid to color transfer). However, considering the fastness of the coating, it generally has better fastness after rolling. In order to ensure good fluorescence and take into account fastness, it is generally recommended to place it in the second place at the end.
(6) The fastness of the baking method during fixation is better than that of the steaming method, and a single flat wash can also improve the fastness. However, in order to avoid affecting the fluorescence, coating printing generally only uses hot and cold water washing instead of soap
Wash; If printed with other dyes, it should not be excessively soap boiled.
(7) In order to maintain a rich and vibrant color and fluorescence, the amount of fluorescent coating used during printing is much higher than that of general coatings. However, in order to ensure its soap washing and rubbing at such a high amount
Washing fastness requires not only a high amount of adhesive, but also the uniformity and fineness of fluorescent coating particles. Generally, it is better to control it at around 0.7 dou m.
(8) Michelin adhesive MR-96 can also be used as a general coating printing adhesive. The amount of paint used is slightly lower, and the amount of adhesive used can also be correspondingly reduced. The dosage of emulsifier M can be adjusted according to the color
Adjust the thickness of the slurry appropriately.
(9) If emulsified paste A is used instead of emulsifier M for printing color paste, the rubbing fastness is slightly poor.
(10) Emulsifier M has emulsifying and thickening effects, and the recommended dosage is generally not more than 3% to 4%. It is very sensitive to electrolytes, and salts such as ammonium sulfate can cause it to condense, so it is not suitable to be added.
