Add 1-3 g/l AVCO-LEVOLUZE 200. Load the fabrics. Treat for 5-10 minutes at 30-40°C, and start the usual dyeing process.
-
Bleaching aid
AVCO-LEVOLUZE 200 is used for improving the absorbency and whiteness of cotton fabrics in a post reductive bleaching process after the peroxide bleaching step.
Use the following recipe:
AVCO-LEVOLUZE 200 1-2 gr/l
Sodium-Hydrosulfit 2-4 gr/l
Caustic Soda (50%) 2-4 gr/l
Treat at 70-80°C for 15-20 minutes followed by hot and cold rinse.
-
Union dyeing of cationic and anionic dyestuff.
Use 1-2 gr/l of AVCO-LEVOLUZE 200 as an anti-precipitant in one bath dyeing of cationic and acid dyestuffs.
-
Dyestuff stripping
Use 2-3 gr/l AVCO-LEVOLUZE 200 together with a reducing agent and caustic soda.
-
Machine cleaning
Use 2-3 g/l AVCO-LEVOLUZE 200 together with hydrosulfite and caustic soda.
-
Soaping off Reactives
Use 0.5 -1 g/l AVCO-LEVOLUZE 200 in the normal soaping process. High fastness properties are achieved. Because of the many possibilities of using this special product, contact AVCO laboratory for specific information.
