Although nonwoven
fabrics can be dyed using either batchwise or continuous processing methods, consideration must be given to both the nature of the fibre type and fabric construction, especially in the case of blend fibres [19]; both dyes and pigments can also be applied by printing [19]. The coloration of nonwovens is currently limited to applications that include floor coverings, wallpapers, furnishings, table and bed linen, shoe linings, as well as single- or limited-use protective clothing; garment interlinings are also often coloured [5]. Despite the industrial importance of nonwoven fabrics and the
fact that the dyeing of nonwoven goods is commercially practiced,
research into the dyeing of such fabrics has received surprisingly
scant attention over the past fifty or so years
