6.2.4.1 Growth in Jute Dyeing and Acrylic Fibers Dyeing is Expected to Influence the
Basic Dyes Segment Positively
Arikan, Sorption of
basic dyes from aqueous solution by activated sludge, J.
Disperse dyes give excellent overall fastness properties with polyester whereas
basic dyes are water soluble cationic dyes where the coloured part has a positive charge, interacts with the negative group (either carboxyl or sulfonic acid group) of the fibre molecule (Choi et al., 2000).
Royce Associates, a sister company of Royce International, is not a part of this transaction and will continue to manufacture and supply its line of reductive chemicals, solvent and
basic dyes, color concentrates, additives and other specialty chemicals.
Arianor[R]: complete range of
basic dyes for semi-permanent or permanent hair dye (non-oxidative or oxidative applications).
Majority of the dyes stain tissues in differing degrees of intensity of the same color; however, certain tissue components, which in the presence of certain
basic dyes, will stain a color other than that of the original color of the dye.

basic dyes from synthesis textile effluent by activated carbon prepared from Thevetia peruviana, Indian Journal of Chemical Technology, 19: 311-321.

basic dyes adsorption from aqueous solutions on activated carbon and new correlations," The Journal of Chemical Thermodynamics, vol.
Cationic dyes known as
basic dyes are extensively used in dyeing of textile fibers such as cotton and polyester [1].
The dyes do not bind to the fabric completely and its loss in wastewaters depending on the class of the dye can vary from 2%) for the
basic dyes to 50% for the reactive dyes, causing serious environmental problems (Park, Choi 2003; Mass, Chaudhari 20055; Pandey et al.
[8] Acidic structures would be stained by
basic dyes, while basic structures would be stained by acidic dyes.
About 50% of reactive dyes, 20% disperse dye and 2% of
basic dyes being unfixed on fabric are released in wastewater (Tan et al., 2000; Boer et al., 2004).
