The acid fixing agent f-925 is nylon fabric in the process of acid dyeing, water resistance, seawater, washing, sweat, etc.Features:
1. One bath processing efficiency is high (usually it is not necessary to add acid), it is convenient to use.
2. The dye does not fall off when processing, resulting in color difference.
3. After solid color treatment, it has little effect on other fastness (daylight fastness, friction fastness..., etc.).
Properties:
Outside view............Dark brown transparent liquid.
A copy of............Aromatic sulfonic acid, polymer
Ionic............Anionic activity
Ph............2 + 1
Solubility............Cold water soluble
Stability............Good for dyeing acid and alkali stability.
Usage:
Staining method:
Acid fixing agent f-925...3 ~ 5% O.W.F
Glacial acetic acid (d)).....................Moderate amount (adjusted PH value 3~4)
Temperature: 70 ℃
Time: 20~30 minutes
Can be in after completion of dyed, cooled to 70 ℃, with bath slowly add acid fixing agent F - 925, dealing with fixing agent directly.
(1) Acid Dyestuffs and other auxiliaries.
(2) acid fixing agent f-925...2 ~ 3% O.W.F
(3) the water to wash
Notes:
The above is the reference usage and usage, the actual amount depends on the equipment condition of each factory, and the quantity is added or decreased.
