4. Conclusion
The purpose of this study is to investigate the effect
of mordant type on dyeing properties and colour fastness
(light, wash and water fastness) of wool fabrics dyed with
indicaxanthin. It was found that the K/S value of dyed
wool fabrics increased in the order of dyeing using KAl
(SO4)2 > MnSO4 > CoSO4 > FeSO4 > none > ZnSO4 > CuSO4. It was
found that KAl (SO4)2, MnSO4 and CoSO4 were the best mordants
for the improvements of colour strength (K/S) and light fastness.
