Extraction of Natural Dye from Osyris Quadripartita and Application in Dyeing of Cotton Fabrics
Natural dyes are widely used in the coloring of food, leather and wood [1]. Traditionally they were the only colorants for textile fibers like wool, silk, cotton and flax. Their use in textiles declined drastically with the introduction of synthetic dyes in 1856 [2-6]. Presently the use of synthetic dyes is estimated at around 10,000,000 tons per annum [7-11]. The manufacture and use of this la...
متن کاملDyeing 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 کاملAchillea Millefolium, a New Source of Natural Dye for Wool Dyeing
Today, natural colorants are emerging globally due to the fact that they are safer and more environmentally-friendly. Natural dyes have been employed in dyeing Persian carpet piles for many years. In this study, the dried Achillea was used for dyeing wool yarns. The Iranian wool yarn was scoured, mordanted using Cu, Sn, Al salts and then dyed with different amounts of dried Achillea powder. Tag...
متن کاملComparison of dyeing of polyester fibers with natural dye and bio-mordant
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 ...
متن کاملUltrasonic Assisted Extraction of Natural Pigments from Rhizomes of Curcuma Longa L.
Ultrasound-assisted extraction (UAE) was evaluated as a simpler and more effective alternative to conventional extraction methods for the isolation of curcuminoids from turmeric plant rhizomes. The turmeric samples were extracted under indirect sonication in an ultrasonic bath, and compared with the conventional methods. It was found that the yield of ultrasound-assisted extraction was approxim...
