Our BWP 422 is a NON- Formaldehyde Color Fixing Agent, it's mainly used for textile printing process.
BWP 422 Color Fixing Agent is a cationic polymeric compound.
Specifications:
Appearance: light yellow viscous liquid
Solid: 50±0.5%
PH (1%water solution): 7 ~ 10
Water-solubility: easy to dissolve in cold water
APPLICATIONAND CHARACTERISTICS:
1. Further improve the effect of color fixation with the reactive grouping in the molecule
2. Without and even unable to release free formaldehyde. According with the requests of the environment protection
3. Excellently used in dye with the active and neuter dyestuff and the anionic dye, especially application in the active dye
INTRODUCTION OF THE USAGE:
Dosage of fixing agent: 0.5% ~ 2% (o. w. f )
Temperature of fixation: 45 ~ 60ºC
Time: 20 ~ 30 min
PH: 6 ~7
Technological flow:
dyeing → watering (→ soap boiling → watering) →fixation →watering → machining
Notice:
1, Before fixation, washing the costuming inside out with the clean water, lest the leftover should influence on the effect of the color fixation
2, After fixation, also washing the costuming with clean water, lest should influence on the next working procedure
3, The PH also could influence the color fixation and the color and luster of the fabric, please adjust the PH according the practice
4, The increase of dosage of fixing agent and the up-down of the temperature are good to enhance the color fixation, but too high may be lead to color change
5, According to the practice , the plants could rectify technics to reach the best color fixation through the sampling
PACKAGEAND STORAGE:
1. 50kg or 200kg net in plastic drum
2. Keep in dry and airy place. Get out of raying. Shelf life: 6 months
