Handwoven carpets as one of the main export items Iran during Qajar period underwent significant integration with world economy after a series foreign companies were established. As result, design, pattern, dyeing, and even weaving techniques changed significantly. There have not been enough considerations all these effects so far. We investigate such process had on Iranian (patterns, sizes, co...

The aim of this research is to develop new mordants and a wide range of colors for natural dyeing of silk. In this study, two new erbium(ΙΙΙ) complexes, [Er(AO)(H2O)7](OAc)3 and [Er(AMH)(H2O)6](OAc)3 (AO = acridine orange, AMH = azomethine-H, and OAc = acetate anion), were synthesized, characterized and used as a mordant for the natural dyeing of silk yarns with an aqueous extract of green waln...

Before the First World War, almost all dyes were applied from solution in an aqueous dyebath to substrates such as cotton, wool, silk and other natural fibres. However, the introduction of a man-made fibre, cellulose acetate, with its inherent hydrophobic nature, created a situation where very few of the available dyes had affinity for the new fibre. Water-soluble anionic dyes had little substa...

Blood testing has been used as an essential tool to diagnose diseases for decades. Recently, there has been a rapid developing trend in using Quantitative Phase Imaging (QPI) methods for blood cell screening. Compared to traditional blood testing techniques, QPI has the advantage of avoiding dyeing or staining the specimen, which may cause damage to the cells. However, most existing systems are...

In this work, raw fibers of a local species of stabraq (milkweed) were scoured, bleached and blended with cotton fibers with a ratio of 75/25 (cotton/stabraq). The improved stabraq fibers, scoured and bleached cotton and the blended fibers were spun into fine yarns and then they were subjected to dyeing with two types of reactive dyes namely, cold brand and high exhaustion brand reactive dye at...

The main objective of this work was to increase the retarding effect of the acid dye Telon(®) Blue RR (C.I. Acid Blue 62; DyStar, Frankfurt, Germany) release on polyamide fibres dyeing by encapsulation of the dye in liposomes as an alternative to synthetic auxiliaries, in order to reduce effluent pollution. The retarding effect achieved with the use of mixed cationic liposomes of dioctadecyldim...
