The acid donor for the quick and level dyeing of polyamide with acid or 1:2 metal complex dyestuffs

A quick and level dyeing of polyamide requires to obtain  the maximum rate of dyeing by optimising a combination of time, temperature, dyestuffs, auxiliaries and pH.

The fundamental dyeing mechanism for polyamide mainly depends on temperature and pH.Due to the increasing cationic character of the fibre and at the same time the decreasing pH the anionic acid dyestuff exhausts quantitatively on the fibre.
