A natural dye extracted from the leaves of Mimusops Elengi Linn and its dyeing properties on cotton and silk fabrics

Environmental friendly exploration of cinnamon bark ( Cinnamomum verum ) based yellow natural dye for green coloration of bio‐mordanted wool fabric

“…Upon application of heat, light, crocking, detergents, and so forth the firmed color resist detaching where on the grayscale after assessment; good to excellent fastness rating have been observed 30,51,52 . Similarly, the reduction power of metal, the nature of fabric dye and the formation of firm metal dye complex after MW treatment also valorizes the coloration of wool 53–55 . Hence, MW treatment has not only reduced the number of mordants but also has developed firmed shades after tunning of the fabric surface.…”

Environmental friendly application of ultrasonic rays for extraction of natural colorant from Harmal (P. harmala) for dyeing of bio-mordanted silk

“…Depending upon the mode of isolation, the dyeing conditions and the optimum amount of metal salt used (%) has given the variety of shades with yellowish red tones through metal-dye complex formation onto fabric, where the reduction and polarizing powder of metal is the key factor. 21,53 The color coordinates given in Table 1 reveal that mostly the chemical mordants have produced brighter shades with reddishyellow hue but the application of 7% of tannic acid (T.A.) during dyeing (meta) of US treated silk fabric (RSF) with the U.S. treated aqueous extract of harmal seeds at optimal conditions has given darker shade (L* = 50.32) with reddish-yellow tone (a* = 9.07; b* = 21.85).…”

“…17 But these are less effective and sometimes these methods can destroy the nature of potent molecules (colorant) by consuming a lot of heat and energy, solvent, time, economy, and labor, 18,19 For improving fastness rating, chemicals such as electrolytes of Al 3+ , Cu 2+ , Cr 3+ , Co 2+ , Ni 2+ , Fe 2+ , etc. are used, 20,21 but the utilization of electrolysis of Cr 3+ , Cu 2+ , Ni 2+ , Co 2+ , etc. in dyeing is under strict environmental regulation.…”

A low-density cellulose rich new natural fiber extracted from the bark of jack tree branches and its characterizations

“…leaves, bark of branches etc. [ 7 , 8 ]. As a part of our on-going research we report here a new high-quality cellulose rich natural fiber that extracted from the bark of branches of jack tree using a cheap and easy extraction technique.…”
