Dyeing Properties and Color Fabrics Using Natural Dye and Mordant
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...
متن کاملImpact of Chitosan-poly(amidoamine) Dendreimer Hybrid Treatment on Dyeing and Color Fastness Properties of Wool Yarn with Madder Natural Dye
In recent years, chitosan and its different derivatives have been extensively used in surface modification and functional finishing of textiles. In this study, wool yarns used in handmade carpet were treated with different concentrations of chitosan-poly (amidoamine) dendrimer hybrid (Ch-PAMAM) and characterized by scanning electron microscope (SEM), and their dyeing properties were investi...
متن کاملWash Fastness of Textile Fibers Dyed with Natural Dye from Eucalyptus Wood Steaming Waste
Natural dyes are gaining interest due their expected low risk to human health and to the environment. In this study, the wash fastness of a natural coloring matter from the liquid waste produced in the steam treatment of eucalyptus wood in textile fabrics was investigated. Specifically, eucalyptus wood extract was used to dye cotton, nylon and wool in an exhaust dyeing process without the addit...
متن کاملPhotostability enhancement of anionic natural dye by intercalation into hydrotalcite.
The aim of this study is the improvement of the photostability of several natural anionic dyes, carmine (CM), carthamus yellow (CY), and annatto dye (ANA), by complexation with hydrotalcite. The composite of the dyes and hydrotalcite is prepared by the coprecipitation method. CM is successfully intercalated in the hydrotalcite layer when the amount of introduced CM is large. The photostability ...
متن کاملColor Stability of Polished and Glazed Dental Porcelain in Chlorhexidine
Background and Aim: Discoloration is a major concern with regard to the use of tooth-colored restorations. Type of restorative material and surface treatment are believed to play a role in this regard. This study sought to compare the color change of glazed and polished dental porcelain after 30 days of immersion in chlorhexidine (CHX). Materials and Methods: In this in vitro, experimental s...
