Subsequent dyeing in a dye bath is an additional operation, which of course incurs costs. On the other hand, there are a lot of advantages:
Masterbatches are either based on pigments or on dyes. They can be processed using existing converting equipment within established infrastructure. Frankly, there is not necessarily much else to explain.
In order to be able to decolorise pigment-based colorings again, further additives are added to the masterbatches. These allow the decontamination bath, to attack the pigments and convert them into soluble, extractable components
“Design-from-Recycling” requires a sophisticated "Design-for-Recycling” to make the production of high-quality recyclates possible in the first place. Prerequisite for this is a suitable combination of a coloring process with an innovative decoloring, rather decontamination process.
Our decontamination process with simultaneous deodorisation, removal of NIAS and decolourisation is a solid-liquid extraction within a modified mechanical recycling process.
It is a high quality reprocessing of the large multi colored fraction into white or transparent recyclates to increase the availability of high-quality recyclates with simultaneous optimisation of the recyclate quality
It is ecologically and economically valuable - worth all the effort
