Henna stone is a lesser-known commercially available material used to obtain black henna paste (1). In some countries, including Turkey, local herb sellers sell it as ‘natural stone’, a so-called natural source for black henna. The stone has to be crushed into powder first, and then mixed with water, hydrogen peroxide and, sometimes, natural henna to obtain black henna paste for the purpose of ...

Bleaching of organic cotton fabric can be done with hydrogen peroxide in which Catalase, a non-toxic, environmentally friendly biocatalyst is used to remove the residual H2O2 in a cost effective way for the better improvement of the cellulosic fabric properties. Enzyme treated organic cotton fabric was dyed with a natural dye obtained from orange corolla tube of Nyctanthes arbor-tristis flower ...

Liposomes are lipid-water systems that can carry hydrophobic and hydrophilic materials because of their amphiphilic structures. Application of liposomes in dyeing and finishing textiles is a new technology based on targeting and slow release which can lead to dyeing at lower temperature along with energy savings and lower environmental impacts. In this research work, a practical method for dyei...
