The development of a new continuous dyeing method based on an aerosol delivery system

A continuous method of dyeing polyester yarn has been developed in which yarn is forced into a moving plug within apparatus based on the Fibre-M texturing system. Dye is then applied in droplet form to the yarn plug. The method relies on the dispersion of low-molecular-weight disperse dyes in a solvent medium to provide a uniform application to the core of the plug. The demands of the textile industry require an extension of the method to a wider range of dye types in a water-based medium. This paper describes a feasibility study of an aerosol method of dye application to a yarn plug.
