Accessibility of man-made cellulosic fibres. Part 1: Exhaust application of reactive dyes to never-dried lyocell, viscose and modal fibres

摘要

Exhaust application of a given reactive dye to never-dried lyocell, viscose and modal fibres gave virtually identical levels of exhaustion on each fibre, whether in the presence of salt alone or in salt plus alkali, as well as similar levels of fixation. This suggests that the accessibility and reactivity of the three never-dried fibres for selected reactive dyes, during a typical exhaust dyeing process, are the same.
