CD7.2 Dyes and Fibres    
 

CD 7.2 Dyeing with different dyes and fibres

The Powerpoint presentation shows how acid blue 40, direct red 23 and disperse yellow 7 dye different fibres. The chemical composition of each of the dyes is discussed in relation to the side groups on the different fibres. Intermolecular forces between dye and fibre are discussed in relation to their strength and therefore ability to dye and subsequent fastness.
