Level fast dyeing of wool with nucleophilic amino-alkyl dyes and crosslinking agents-Part 2: using bifunctional crosslinking agents

Covalently binding dyes through reactions between commercially available bi-functional crosslinking agents, wool and aminoethylaminotriazinyl dyes is discussed. In particular, dye fixation, levelness and fastness properties have been assessed and shown to be very promising. The proposed system offers the dyer the opportunity to achieve covalent bonding of the dye to the fibre in a controlled manner, thus ensuring good levelness.
