ARIACRYL Dyestuffs
ARIACRYL dyestuffs are modified cationic dyestuffs which are used for the exhaust and for the continuous dyeing of polyacryl fibers. Some dyes are particulary suitable for dyeing modacrylic, modified polyamide, modified polyester and polyvinylchloride fibers. The card illustrates the use of ARIACRYL dyes in exhaustion method on acrylic fibers.
Dyeing Properties of Acrylic Fibers
Acrylic fibers are produced by either a wet spinning or a dry spinning process. Different types of acrylic fiber have different fiber saturatuin values (SF) and dyeing rates (V).
The SF value indicates the dyestuff binding capacity of the fibers. It is directly rated to the number of acid group in the fiber having affinity to the dyestuff. The SF value is independent of the dyestuff used. The V value indicates the dyeing rate of the acrylic fiber. Wet-spun fibers generally have a higher dyeing rate than dry-spun types. So more retarder is needed to produce level dyeing.
Saturation Factor F
The saturation factor is a dyestuff-rated constant. It is independent of the fiber to be dyed. From the fiber saturation value (SF) and the saturation factor (F) it is possible to calculate the maximum amount of dyestuff which exhausts on to an acrylic fiber (PS Value)
PS = SF/F
Combination Factor K
Cationic dyestuffs influence each other in their exhaustion so only dyestuffs with the same or a similar combination factor. i.e. a similar pick-up rate, should be combines in one recipe. The K values range from 1 to 5. In combination dyeing, dyestuffs with a low K value exhaust onto the fiber first, while dyestuffs with a higher value exhaust slower.
ARIAGAL PAN
ARIAGAL PAN is the retarder that exhaust into fiber during the dyeing process, and complete with the dyestuffs, which are also cationic. This reduces the rate of absorption of the dyestuffs thereby controlling pick-up in the critical range between 85°C and 90°C and preventing unlevel dyeing.
ARIAGAL WA
ARIAGAL WA are added to the dye liquor as nonionic surface-active dispersing agents.
Dyeing Process
1. Scouring
The materials to be dyed are scoured by treatment in the liquor containing 1-2 g/l of nonionic surfactant for 20-30 minutes at 60-70°C, followed by sufficiant rinsing.
2. Dissolution of ARIACRYL Colours
Knead the dye with almost same amount of acetic acid (90-99%), and immediatly add boiling water for complete dissolution of the dye. Water to be used must contain no active chlorine.
3. Composition of Dye-Bath
| A) | Dyes | x% (o.w.f) | ||
| B) | Acetic acid (90%) Sodium acetate anhydrous Glauber's salt |
1.0-2.0% 0.5% 0-10% |
||
| C) | ARIAGAL PAN ARIAGAL WA |
0-3% 0-2% |
A required amount of retarder is figured out from the calculation of saturation value.
4. Dyeing Operation
Prepare the dye-bath at 75-80°C and raise it's temprature gradually to 98-102°C, where dyeing is conducted for 40-90 minutes. After dyeing, cool down the dye-bath gradually to 60°C and rinse the materials thoroughly with hot water.
5. Soaping (for light colour)
| Alapol N-800 | 1 g/l | |
| 20-30 minutes, treatment at 60-70°C Reduction clearing (for dark colour) |
||
| Hydrosulfite NS conc. | 2 g/l | |
| Aqueous ammonia (28%) | 0.7 m/l | |
| 20-30 minutes, treatment at 70°C and rinsing with hot water | ||
6. Softening or Antistatic
This treatment is done in a bath containing cationic softener after dyeing.
