Dyeing |
| ¡¡ |
Only
coloured textiles make fashion. textile materials are dyed with
textile dyestuffs
in aqueous media. the dyeing auxiliaries used in this context
enable the surface level coloration together with the dyestuffs,
the desired depth of shade, brilliancy and fastness. |
| Levelling
agents |
Support
the penetration of the dyebath
into the textile, improve the even dyeing, even out unlevelness.
important chemical components are ethoxylated
fatty alines or fatty alcohols, sulphonated
oils, carbonic acid esters and quaternary
ammonium compounds. trademark:SARABID,
KERIOLAN, EGASOL |
| Crease
preventing agents |
Have
gliding properties and diminish the mechanical contacts during
the dyeing processes. creases, chafe marks and mechanical damage
are avoided. suitable raw materials are natural oils, lecithin
and high molecular polymers. Trademark: BIAVIN,.
VISCAVIN |
|
Dispersing agents |
Keep
the dyestuff in
the dyebaths
in fine distribution and prevent disturbing precipitations.
low molecular polymers, highly ethoxylated
fatty alcohols and sulphonates
are the chemical basis. Trademark: CHT-DISPERGATOR |
| Aftertreatment
agents |
For
dyeings to
improve the colour fastness. the methods of operation are
different: removal of the only superficially precipitated dyestuff
residues, chemical reaction with the dyestuffs
tied to the fibres
or interaction with the reactive groups of the fibres.
Anionic and cationic
polymers with different polymerisation
degrees
show this effect.

Next to these main groups many other important products complete
the range of dyeing auxiliaries: Fibre
protecting agents, ph regulators, dyeing accelerators, enzymes
for jeans finishing, products for the cleaning of dyeing
effluent, defoaming
and deaerating
agents.
