Latest Patents
Kollodzeiski holds a patent for a process that enables the uniform dyeing of polyacrylonitrile fiber materials. The patent, titled "Process for dyeing uniformly polyacrylonitrile fiber materials," describes a dyeing process that utilizes basic azo dyestuffs that are non-quaternized. These dyestuffs do not contain cationic quaternary ammonium groups or cationic N-substituted or N-unsubstituted iminium groups. Instead, they include at least one unsubstituted or substituted amino group, hydrazino group, amidino group, or guanidino group capable of forming salts. The dyeing process is carried out under standard processing conditions for polyacrylonitriles in a slightly acidic medium. This method offers special advantages, particularly in polychromic dyeing, allowing for consistent color shades even during short dyeing periods.
