Variations in the Application of Mordant of Dye Extracted from Coconut Husk on Cotton Fabric

Mordants are substances that help to bind the dye to the fabric to improving the colour fastness and durability of the dye. Dye was extracted using soxhlet extraction method, the percentage yield of the dye was also determined. Three different modant were used in the dyeing process, namely vinegar, table salt and baking soda. Colourimeter was used to collect information on assessment of colours of the extracted dye from coconut husk. The result obtained shows the % yield of extract to be 40 Parsant, which is significantly high, this is an indication that coconut waste is rich colour pigment. The delta value (Delta E) of light fastness of the dye extract on cotton fabric with no modant was higher than the (Delta E) modanted fabric. The modanted, vinegar has the highest (Delta E) with 69.2nm over baking soda 68.2nm, while table salt give the lowest (Delta E) with 61.5nm. The wash fastness quality characteristic also indicate that table salt used as modant has the highest e (Delta E) to be 66.6nm, over vinegar with 52.3nm, while baking soda has a (Delta E) of 51.9nm.
