Fig. 1b. 10 g cationised fabrics were conventionally colored in pigment
baths (2% pigment, owf) with a liquor ratio 1:30 at different
pH values (6–11), concentrations of common salt (0–20 g/l), for
different durations (0–45 min) and temperatures (40–80 ◦C). For
comparison, the same conditions of coloring were carried out using
ultrasound at different sonic power (50, 100, 200 and 300 W). After
dyeing, the fabrics were taken out and treated in the solutions containing
5 g/l binder FSB at 95 ◦C for 15 min using a liquor ratio 1:30,
and then rinsed in tap water and air dried.
