Some Aspects of the Dyeing of Acrylic Fibres, with particular reference to the Pack‐dyeing of Courtelle

Abstract

The general features of the dyeing behaviour and thermoplastic properties of acrylic fibres are discussed in relation to practical dyeing operations, in particular the pack‐ and package‐dyeing of Courtelle in the form of loose fibre and slubbing. General and specific procedures for the application of disperse and basic dyes, consistent with the retention of good condition of the material, are suggested.
