A comparison of the weight reduction behaviours of the two microfibre yarns revealed that the microfibre yarn containing carbon black exhibited a higher dissolution speed than that containing no carbon black. The incorporation of carbon black particles in the polyester fibre matrix therefore accelerates the degradation of the less crystalline sea component during alkali treatment. A cationic dye staining method was used to monitor the alkaline dissolution behaviour of the sea–island-type PET microfibres, and compared with the K/S values and the colour difference, the fk value is the most-desirable indicator for determination of the termination point of the alkaline dissolution process. The colour strength and the colour fastness of the dope-dyed sea–island-type PET microfibre fabrics are superior to those of the normal type.
