dyes. These have increasing amino group contents, respectively, but all dye to the
same depth with disperse dyes. In addition, there are also basic dyeing varieties of
nylon, containing anionic groups capable of binding cationic dyes (Section 4.2.4).
Mixtures of different nylon types in a carpet give attractive tone-in-tone and
multi-colour effects because of their differential dyeing behaviour.
