Effect ofN-Cetylpyridinium Chloride on the Surface Free Energy of Leacril Fabric

Effect of Tannic Acid on the ζ Potential, Sorption, and Surface Free Energy in the Process of Dyeing of Leacril with a Cationic Dye

“…Detailed descriptions of the van Oss et al approach to the surface free energy formulation are given in the numerous papers of these authors (15)(16)(17)(18)(19)(20)(21)(22)(23)(24)(25)(26)(27)(28). Thus, the total surface free energy of a solid or a liquid is described as a sum of the Lifshitz-van der Waals component (London dispersion (main component), Debye polarization, and Keesom orientation), ␥ S LW , and the acid-base interaction, ␥ S AB , which in many cases is due to the hydrogen bonding.…”

“…Also, the value of 61.7 mJ/m 2 for the dyeing of Leacril with 10 Ϫ5 M Rhodamine B can be attributed to the presence of the above groups on the surface of the Leacril and mainly the presence of sulfonate and sulfate end groups on the Leacril fabric that at lowest concentration range of dye in solution are not totally blockaded for the molecules of the cationic dye. It is known that the sulfonate and the sulfate end groups of the Leacril have a strong electron-donor character (15,(17)(18)(19).…”

Electrokinetic and Thermodynamic Analysis of the Adsorption Process of N-Cetylpyridinium Chloride on Polyester Fabric

“…Thus, using surfactants as dyeing assistants improves dye uptake in certain cases. In this context, however, little work has been done using polyester fibers, and practically no work has been reported on N-cetylpyridinium chloride (N-CP-Cl) as a dyeing assistant for polyester (5). In the present paper, we described an experimental investigation of the electrokinetic behavior of polyester treated with different amounts of N-CP-Cl.…”

“…be used for investigating physicochemical surface properties of textile fabrics and the results of these investigations can be correlated with important technical properties of textiles (5). Many phenomena that occur at a solid-liquid interface, such as wettability, particle aggregation, flotation, and dyeing, depend to a large extent on the kind and magnitude of the surface and the interfacial free energy involved.…”
