It was observed that dyeing with H. mutabilis gave fair to
good fastness properties in conventional dyeing. Table 1 shows
L*, a* and b* values and it can be seen that mordants which
show higher value of L* show lighter shades while lower L*
values signify deeper shades for cotton fabrics. Similarly, negative
a* and negative b* represent green and blue, respectively.
The colorfastness to washing was between 4 and 5 as
shown in Tables 2 and 3 which are for silk and wool, respectively.
We have compared the dyeing with conventional
method. The fastness properties of dyed fabrics of cotton
and silk are shown in Tables 4 and 5, while Table 6 shows fastness
properties of wool yarn. Overall, it could be used for
commercial purposes; the dyed cotton fabric, silk fabric and
wool yarn attain acceptable range. The results clearly show
that the aqueous dye of fresh flowers is better than dry flowers
in terms of better dye uptake, reduced dyeing time and cost
effectiveness
