Popis:	Six monoazo dyes were prepared and recrystallized from the appropriate solvent. Their UV and visible spectra were measured. The dipole moments of these dyes were obtained from measurements of their static dielectric constants and refractive indices of dilute solutions in benzene at 20°C. The colour strength (K/S) of nylon 6 fabrics dyed with these dyes was measured. From the results obtained, it was found that there is a relationship between the dipole moment of the dyes under investigation and their colour strength (K/S) on dyed fabrics.
