ADILON DYE-AIO levelling and dispersing agent is recommended for HT-exhaust dyeing with disperse dyes. With its powerful levelling and dispersing action, ADILON DYE-AIO is the product which can widely be used for e.g. jet dyeing, piece goods on beam dyeing units and also for yarn. Due to its excellent non foaming behaviour, it is well suited for piece goods including for automotive end-use.

ECOLOGY AND TOXICITY
The usual hygiene and safety rules for handling chemicals should be observed in storage, handling and use. The product must not be swallowed.
Application:
ADILON DYE-AIO as dispersing and levelling agent in dyeing polyester:
ADILON DYE-AIO is suitable for use on all types of high temperature dyeing machinery. After scouring the goods where necessary, the dye bath is set with fresh water and temperature raised to 60ºC.
Meanwhile, ADILON DYE-AIO is pre-diluted by adding the product to 4-5 times its own volume of warm water.
- ADILON DYE-AIO : 0.5 to 1.0 g/l
- ADILON SAM (sequestering agent) : 0.5 g/l
- Acetic Acid or Acid Buffer adjust pH to : 4.5 to 5.5
- Disperse Dye : x% o.w.f
Add pre-diluted ADILON DYE-AIO to the bath together with other chemicals required (sequestering agent, acid/acid buffer) and circulate. Adjust to pH 4.5 to 5.5.
Add well-dispersed dyestuff, preferably through a sieve or filter.
Raise temperature from 60ºC to maximum dyeing temperature (130-135ºC) at desired temperature gradient. Rapid rates of rise of 2 to 4ºC per minute are possible. Run 30 to 60 minutes. Cool to temperature at which the liquor can be safely drained without causing creasing, then rinse or backscour/reduction clear as necessary.
ADILON DYE-AIO as a stripping agent or re-levelling of faulty dyeing:
ADILON DYE-AIO can be used to correct unlevel dyeing or to reduce the depth of dyeing dyed too heavily.
Treat for 30 to 60 minutes with:
- ADILON DYE-AIO : 2 to 5 g/l
At maximum dyeing temperature, this treatment will hold the removed dyes in the bath. If shade corrections are necessary, these should be carried out after replacing all or most of the bath. Otherwise, such high concentrations of ADILON DYE-AIO will not permit good exhaustion. Stripping or re-levelling treatments should be followed by thorough rinsing and reduction clearing to ensure maximum fastness.
- Reduction clearing treatment
– ADILON ARCO : 0.3 – 0.5% o.w.f
– Acetic acid : xx
– Maintain pH : 4.5 – 5.0
Treat the goods for 15 to 20 minutes at 70 to 80ºC to achieve optimum fastness and clarity of shade.
