Extraction of natural dye from floral parts of African marigold (Tagetes erecta L.) for dyeing cotton fabrics and its fastness
Author(s): Amit Lohar and Jayoti Majumder
Abstract: The present study demonstrated dyeing of cotton fabric with the pigment extracted through various methods from marigold (Tagetes erecta L.). Marigold creates the colour range from yellow to orange. Dyeing of 100% cotton along with mordanting techniques which included scouring, mordanting and pre mordanting was carried out. After scouring, mordanting and dyeing the fabrics were evaluated for colour measurements in HunterlabD25LT Chroma Meter for L* a* and b* values. The L* value were found to be superior when the fabrics were treated with alum. The highest L* value (64.31) was obtained in T9 i.e., pre-treatment of Alum + 70% alcohol + shade dry in marigold. The increased a* value was found in T3 with (12.71) stannous chloride + 70% alcohol + shade dry in marigold. b* T3 with (42.07) stannous chloride + 70% alcohol + shade dry was found in marigold dyed cotton fabric respectively. Good light fastness, wash fastness and rubbing fastness were observed in case of fabrics mordanted with copper sulphate. These findings reveal that Tagetes erecta L. can serve as a potential source of natural colorant which can be used in textile industry for dyeing purpose.
