“…the determination of sorption isotherms [1,2], the elucidation of mixture dyeing [3,4] and the effects of silk and dye structure [5][6][7][8]. More particularly, the sorption and diffusion of acid dyes in a silk fibre have been investigated from several points of view, e.g.…”

The sorption behaviour of sodium 1-phenylazo-2-hydroxy-6-naphthalenesulphonate and sodium 1-(3methylphenylazo)-2-hydroxy-6-naphthalenesulphonate by a silk fibre was investigated in the presence and absence of a bolaform electrolyte. The addition of the bolaform electrolyte influenced the dye sorption to an extent that was dependent on the pH of the dyebath. At pH 3 the amount of dye sorbed by the silk fibre decreased slightly with increasing bolaform electrolyte concentration, while at pH 4 and in pure water it increased. The sorption parameters determined from the sorption isotherms considering the dual sorption mechanism were affected by the addition of the bolaform electrolyte: most importantly, the partition coefficients were significantly enhanced. Furthermore, the effects of the bolaform electrolyte on the dye sorption by the silk fibre were quite different to those seen with a nylon 6 film.

“…For the latter (ABs), Buttingsrud et al [68] studied the relationship between the molecular electronic structure and the position of the absorption maximum for 191 azobenzene dyes. General structure of thiadiazolyl azo dyes studied by Giorgi et al [66] prediction decreased to 5.4 nm. Therefore, the authors concluded that the N=N bond, and particularly the bond length, play an important role in adjusting the colour of dyes.…”

Dyes have been applied and are playing an increasingly important role in many industries, including the textile, printing, medical and energy industries. Their wide applications imply that specific dyes possessing given properties need to be effectively designed. The present review aims to survey information related to activity/property research of dyes that has been published in the past two decades. Emphasis is laid particularly on studies based on quantitative structure–activity/property relationships that have contributed to the theoretical design and application of dyes. Finally, the perspectives of quantitative structure‐activity/property relationship studies are set out in order to show how this method may be used to design new dyes and to evaluate their different properties. The challenges facing these studies are also outlined.

“…The thermodynamic affinity of acid dyes also was found to increase with greater conjugation in its structure (Giorgi et al, 1991). When silk fibers are degummed with 30% citric acid, the removal of sericin was almost complete.…”
