Abstract

The effects of various carriers on the reduction of the glass transition temperature (Tg) and the dyeing transition temperature (Td) of an acrylic fibre in a cationic dyeing system have been investigated. Linear relationships were found between the concentration of carriers in the fibre and the reduction of the Tg and the Td of the fibre. The efficiency of various carriers in reducing the Tg and the Td, when compared in terms of the molar concentrations of the carriers in the fibre, was found to be similar, regardless of the carriers used.
