Improving light fastness of natural dyes on cotton yarn
The objectives of this study were to evaluate the light fastness of selected natural dyes (madder, weld and woad) and the effect of some commonly used antioxidants and UV absorbers on the light fastness of these dyes. The photofading rate curves of madder and weld fixed on cotton correspond to type II fading rate curves described by Giles. These results are in concordance with those of Cox-Crew...
متن کاملImproving light fastness of Reseda Luteola natural dyed wool with antioxidants and UV absorbent
One of the problems of natural yellow dyes (weld) is their low stability against light and their high fading rate. One of the main destructive factors in pale of color fibers and hand-woven carpet is the high-energy ultraviolet radiation which causes chemical bonds to break and optically damages of organic structures. In this study, the effect of some antioxidants (gallic acid, ascorbic acid) a...
متن کاملImprovement in Wash Fastness of Dyed Silk by Aftertreatment with Commercial Syntan/Metal Salts
Silk yarns were dyed by using commercial basic, reactive and pre-metallised acid dyes. An aftertreatment with a commercial synthetic tanning agent (syntan) was applied to the dyeings and the aftertreated dyeings were further treated with metal salts in an attempt to improve wash fastness properties. When all samples (untreated, syntanned and syntanned/ backtanned speciments) were subjected five...
متن کاملGreen Dyeing of Silk Fabrics in the Presence of Pomegranate Extract as Natural Mordant
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...
متن کاملDyeing of Cotton Fabric with Natural Dyes Improved by Mordants and Plasma Treatment
Nowadays, there is a great tendency for eco-dyeing and finishing of textiles with natural products. several natural dyes have been used for dyeing of protein fibers but a low number have the ability to dye cotton fiber because of low affinity of cellulose to the natural dyes. In this study madder and weld natural colorants were used to dye cotton fabric premordanted with three metallic salt...
