4 textile Multi-functionality Imerol ® Blue liq has more than one rabbit in its hat. The combination of its exceptional properties, based on the Singulet Bleaching Technology, opens new doors for the exhaust bleaching world. pH 12 11 10 9 8 7 10.5 Classic Blue Magic 0 10 20 30 40 50 60 Wetting colour chronicle 2 | 2012 minutes High penetration power (Tampex penetration test) % Enzyme-Activity 100 80 60 40 pH2 pH4 pH6 pH8 pH10 pH12 % Enzyme-Activity Washing 0 g/l 1 g/l 2 g/l 3 g/l 100 90 80 70 60 50 40 30 20 10 Strong detergency (wash test on standard soiled fabric) No foaming No foaming behavior Alkali stable Alkali stable up to 6°Bé and biodegradable Key functions Oxygen-active donor Wetting-washing and dispersing agent Balance activation/stabilization Collapsor of pH Bactosol ® SAP liq c Usual Catalase 30°C 40°C 50°C 60°C 70°C With Imerol ® Blue liq the following features are granted: High wetting and penetration power (Tampex penetration test) to convey quickly the bleaching bath to the core of the fiber. Strong detergency (wash test) and dispersing behavior to remove the contaminants and keep them away from the fiber. No foaming behavior. Machine turbulences are never an issue. Stable up to 6° Bé NaOH, suitable for all exhaust bleaching applications. Protector against cellulose degradation Removes fatty substances (high absorbency) Disperses oiling agents (no redeposition, no spots) Economic Flexibility Bactosol ® SAP liq c is a hybrid catalase enzyme with a wide scope of application: fl exible pH (4 – 9), fl exible temperature (20 – 70°C) and fl exible application (discontinuous – continuous). There is no more need of perfectly adjusted pH and temperature: the elimination of peroxide is total in every case! The new Blue Magic process can be used in all the different forms of discontinuous pretreatment. From yarn to cotton flocks, over terry towels, woven and knitwear, Imerol ® Blue liq delivers great results. Yarn packages Woven fabrics Knitwear Absorbent cotton
The combination of Imerol ® Blue liq and optical brighteners makes you able to achieve highest degree of whiteness.
