ASSESSMENT THE COLOR FASTNESS OF DEVELOPED PRINTING PASTE USING INDALCA GUM WITH ACID DYE

Various class of dye have different fastness properties to various extents. Even dyes those who are belonging to the same class have widely varying fastness properties. A single dye which dyes all the textile material (fiber) is not made yet. In present study acid dye was used for silk fabric because silk is a protein fiber so acid dye is excellent for printing and Indalca gum is stable in both acidic and alkaline conditions so it is good for printing with acid dye on silk. Applying colour on fabric in different shape or design is textile printing. In textile printing colour is bounded with fabric. Various printing style were used for printing. After printing or dyeing it is necessary to have excellent fastness. For checking the fastness, various tests was done. These were washing, rubbing fastness and blue wool scale was used to assess the light fastness.
