Features of this Comix Bi-Flow 100 overflow machine for dyeing woven and knitted fabrics are described. A standard and a specialized version are available. In the latter case maximum automation is possible.

Madder red - a revolutinary colour

The history of Madder Red (or Trudey Red) dyes, and the dyeing process involved, are traced fro their origins in the Near East, via developments in France, to attempts to master the process in Manchester and Glasgow in 1781-1785.

New generation of dyeing machines

The VN Super HT jig dyeing machine from Vald Henriksen is discussed. A fault on the fabric tensioning system needs to be corrected.

Effect of dye characteristics on their compatibility in mextures as assessed through colour coordinates

Three different binary mixtures prepard by mixing disperse dyes havin close hues were applied to polyester fabric at 4.0 total depth. The compatibility of dyes in these binary mixtures was assessed qualitatively through the use of various plots constructed from differences in CIELAB colour coordinates with respect to the undyed substrate,..

Optimization of dyeing process

The various aspects of standardizing dyeing processes for different natural and synthetic fibres are examined.

Dyeing and finishing polyester/cotton - the commercial approach

Fabrics woven from blends of polyester and cotton are used in large quantities for a wide range of clothing purposes. It is vital, therefore, that the most cost-effective finishing methods are used on these fabrics.
