Refaktan EBV
Aqueous solution of anionic and non-ionic surfactantsProduct characteristics
Aqueous solution of anionic and non-ionic surfactants. Its characteristic features are high wettability and good dispergation and emulsifying properties.
Use
REFAKTAN EBV is used in the textile industry for continuous dyeing of wool and PAD, for spraying of wool yarn and continuous dyeing of cellulose materials.
Product properties
REFAKTAN EBV is a yellowish liquid of an anionic character.
REFAKTAN EBV must comply with the following quality characteristics:

Product processing
Continuous dyeing
Quality of the wool material, especially good spinnability is maintained. Its main advantage is a short ageing time. Milder processing conditions are enabled by the use of more efficient auxiliary preparations with a more versatile effect.
Acidic 2:1 and 1:1 metal-complex dyes – Foulard process, ageing, washing drying.
The padding solution contains:
REFAKTAN EBV |
15 to 35 g/liter |
|
Thickener |
5 to 12 g/liter |
|
Acetic acid 60% (or possibly formic acid) |
15 to 25 g/liter |
|
Dye |
as necessary |
Well-solved dye is mixed with the thickener at a temperature of 90 to 95 °C, the solution is cooled down to 50 °C, REFAKTAN EBV is added and the mixture is stirred for 10 to 15 minutes. After that, acetic acid is added. This solution is used to pad the material in a Foulard machine (squeezing 100%), which is subsequently aged for 10 to 30 minutes with saturated steam. The time can be extended depending on the type of used dye and the required color shade. This is followed by washing and drying. REFAKTAN EBV is usually sufficient to remove not fixed dye and thickener during subsequent washing. For saturated colors ALMIPAL ABA is added.
Acidic, metal-complex dyes.
REFAKTANT EBV is dosed into the dyeing bath containing a wetting agent, defoaming agent, thickener, acetic acid etc. in the quantity of 3 to 5 % (depending on the dyeing technique and used yarn). The “dyed” material is aged with saturated steam (fixation) having a temperature of 95 to 98 °C for 45 to 60 minutes. This is followed by washing and drying.
Substantive dyes, padding method
The padding solution contains:
REFAKTAN EBV |
10 to 25 g/liter |
|
Alginate thickener |
2 g/litre |
|
Urea |
100 to 150 g/liter |
|
Dye |
as necessary |
Padding temperature 20 to 25 °C, squeezing 70 to 80 %. This is followed by maturation in a lap for 10 to 24 hours, washing with cold and hot water, stabilization and rinsing.
