It was found from the study that isolated dye from
the flowers of Erythrina suberosa can be successfully
used for dyeing of wool to obtain a wide range of
soft and light colours by using combination of
mordants. With regards to colour fastness, test
samples exhibited excellent fastness to washing
(except for pre-mordanting using Lemon juice:
Potassium dichromate combination) excellent
fastness to rubbing and good to excellent fastness to
perspiration in both acidic and alkaline media and
fairly good fastness to light and these data also
helpful for textile industries. These results give us
different data for evaluation of fastness properties
under consideration and which are helpful for textile
industries to utilization of Natural dyes isolated from
Erythrina suberosa
