Wool—Polyester Fibers. The 45/55 wool—polyester blend is the most common fiber combination in the worsted industry. Strength and exceUent dimensional stabiHty of the polyester fiber enable the creation of lightweight wear fabrics not obtainable before. Economy has modified the fiber ratio and 30/70 and 20/80 wool—polyester blends are as common as the classical 45/55 blend. Disperse dyes for polyester and acid or neutral premetaUized dyes for wool are employed in a one-bath process. Should cationic dyes be used for the wool portion, a one-bath procedure can only be employed for light to medium shades, whereas dark shades require a one-bath two-step process. Wool blends should not be dyed above 105°C in order to avoid deterioration of the fiber quaHty. 

A number of researchers studied azo disperse dyes derived form substituted 2-aminothiophenes 90 in the dyeing of synthetic fibres [178-187], blended polyester wool fibres [188,189] and also in optical data store devices [190]. 

Figure 8.11 shows the percentage exhaustion of red, yellow and blue colour dyes on a fabric made of polyester, cotton and wool blended fibres versus time. Ideally, the acid dyes adsorb onto the wool, the direct dyes adsorb onto the cotton, and the disperse dyes adsorb into the polyester fibres. Figure 8.11 shows that.
