Our BWF 501 is a CATIONIC polymeric compound.
BWF 501 is a FREE formaldehyde color fixative agent.
It's mainly used for color fixing for reactive dyes.
 
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
