Cotton is the most popularly used fiber around the world largely due to its comfort and feel to the individual’s body. It is treated in its natural form or made anew through forms like modal, viscose or blended with synthetics. The dyes used for coloration of cotton fibre mainly constitute the reactive dyes and vat dyes though a small but vital share is held by Napthols /azoic bases. These are helpful in achieving vibrant and deep hues besides offering a large number of benefits like bleach/wash/light fastness, cost efficiencies etc.
