Investigation of disperse fluorescent ink formulation via thermal transfer printing for polyester substrate

Abstract

Disperse fluorescent ink was controllably prepared via the cyclic sander grinding process and used for thermal transfer printing on a polyester substrate. Via process optimization, 0.1% pH regulator triethanolamine and 0.15% surfactant NP-12 were added in the disperse fluorescent ink. The lightness L* of the polyester substrate was 101.84 and the saturation C* was 84.21 within thermal transfer printing on the polyester substrate. Compared with flat screen printing, the bending rigidity and bending hysteresis moment of the ink-jet printed polyester substrate presented a slight change. The fluorescent effect of the printed polyester substrate was increased to 165.65, and the fluorescence reflectivity increased 4.1% at the maximum emission wavelength λmax = 510 nm. The color fastness of the printed polyester substrate was improved. In particular, the wet rubbing fastness was enhanced by one grade after the ink-jet thermal transfer printing.

Colorful Fluorine‐Free Superhydrophobic Polyester Fabric Prepared via Disperse Dyeing Process

“…Accordingly, the a* and C* values representing the red color increased, because the dye was migrated into the polyester fiber and the molecular bonding between the dye and fabric was stabilized during thermal aging. [ 25 ] The photographs of color change of polyester fabrics before and after alkaline hydrolysis, dyeing or thermal aging were shown in Figure S2 of the Supporting Information.…”

“…Disperse Blue 56 showed higher color fastness to washing since the dye was migrated deep inside the molecular chains and its bonding force with polyester fabric was stabilized during thermal aging. [ 25 ] Therefore, the colored, fluorine‐free, superhydrophobic polyester fabrics fabricated in this study can have advantages of easy care since they can repel stains readily and also have color fastness to washing. As for their color fastness to light, color change arises when electron transition occurs with the absorption of light by the dye.…”

“…Disperse Red 277, the fabric showed improved light fastness after thermal aging, irrespective of alkaline hydrolysis, and the reason is the same as that of its color fastness to washing. [ 25 ]…”

Color-changing intensified light-emitting multifunctional textiles via digital printing of biobased flavin

“…1 Fluorescent dyes are functional dyes, and the emission light usually is of higher wavelength than the absorbed light. The uorescent effect has been widely used in many different elds, such as biological imaging, 2 probes, 3,4 and textiles; [5][6][7] smart textiles is one such eld gaining tremendous attention. The development of photochromic and uorescent textiles using strontium aluminate pigments has been explored.…”

Influence of diffusion behavior of disperse dye ink on printing accuracy for warp-knitted polyester fabrics

“…4 The main two methods for polyester ink-jet printing are transfer and direct ink-jet printing. 5 Many disadvantages, such as environment pollution, high cost, and low transfer rate were found in transfer ink-jet printing, which could be due to the large numbers of transfer papers. Direct ink-jet printing can solve these problems and has attracted much attention due to being environment-friendly, quick proofing, and requiring less manpower and time compared with transfer ink-jet printing.…”
