In this study, dyeing of two regenerated polyester fibers, poly-trimethylene terephthalate (PTT) and poly-lactic acid (PLA), with natural dyes were compared with that of poly-ethylene terephthalate (PET) fiber. Lac was used as the primary natural colorant while Catechu was chosen as a natural color that can also act as a biomordant. The effects of temperature, initial pH of dye bath and dyeing ...

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...

An ecological approach has been obtained by using natural dyes and mordant for dyeing process. Fabrics dyed using myrobalan extract as natural mordants and green dye. A red color were obtained by using theses mordants. The color of dyed fabrics was investigated in CIELab L, a and b and K/S values. Finally, all dyed fabrics were tested for wash and light fastness properties as per ISO standard t...

An ecological approach has been obtained by using natural dyes and mordant for dyeing process. Silk fabrics dyed using natural mordants: powder of sour pomegranate and sweet pomegranate and mixture them. A beautiful red color were obtained by using theses mordants. The color of dyed silk fabrics was investigated in CIE Lab L, a and b and K/S values. Finally, all dyed fabrics were tested for was...

In this investigation dyeing of alginate fiber was carried out after cationic treatment of 11 EPTAC (2, 3-Epoxypropyl Trimethyl Ammonium Chloride). Optimum dyeing process and 12 parameter show good dyeing performance when alginate fiber dyed with rhubarb dye. In addition 13 to cationic treatment is taken into account for alginate fiber to improve fastness, color strength, 14 breaking strength. ...
