wastewater (Xiuliang et al., 2013). These were disadvantageous in terms of environmental and total process cycle prices.
Concerning dyeing with Hibiscus extract, it seems that these problems do not arise. Indeed, it was shown in the present study that it is possible to obtain high yields and good fastness dyeing without the use of mordant.
A comparative study was done between a natural dyeing with Henna’s leaves (Shaukat et al., 2009) needing a mordanting step (usually used for natural dye) and a natural dyeing with Hibiscus extract in terms of dyeing process prices (see Table 4).
For the Henna’s dyeing, two mordant were applied: the alum and the iron. Whereas, for Hibiscus dyeing, a cationizing step of cotton with Stabifix NCC was made.
Based in Table 4, it is obvious that the cost of the natural dyeing obtained from Henna’s leaves was greater than Hibiscus dyeing whatever was the nature of mordant applied for Henna’s dyeing
