Basic Dyes for Synthetic‐polymer Fibres

The retarding action of polyacrylamide in acrylic dyeing

“…Cationic dyes have greater potential than disperse dyes for dyeing anionically modified acrylic fibres because of their brilliancy and ability to produce fast dyeings on these fibres [7]. The cationic dye molecules are strongly adsorbed onto the anionic sites, allowing no migration.…”

Migrating Cationic Dyes for Acrylic Fibres

“…Improvements, such as brighter colours and wider fields of application, were being sought; on the whole, consolidation of existing dye ranges was the main activity. Accordingly, an article on dye synthesis, published in Review of Progress in Coloration by Mayer and Siepmann [3], identified no new frontiers, but discussed the different types of dye structure (primarily those from the years 1963 to 1969). The same applies to an article by Raue [4].…”
