non-ideality, it will tend to reduce differences between calibraiion and predictior;. To do this of course is not always possible, particularly where the effect of changing dyebath conditions is under consideration, e.g. liquor ratio, electrolyte concentration, pH and dye concentration. To attempt calibration experiments to adequately cover the results of such changes would remove the need for ...

This paper reports the studies available on the characterization and chemical/biochemical analysis of natural dyes; extraction of colorants from different natural sources; effects of different mordants and mordanting methods; conventional and non-conventional methods of natural dyeing; physico-chemical studies on dyeing process variables and dyeing kinetics; development of newer shades and anal...

pdates on yarn dyeing technology U were shared among the 83 participants in the AATCC symposium held at Southern Pines, N. C., in April. The symposium included 11 presentations, problem solving sessions and a discussion session on the challenges of package dyeing microfibers. Developed by AATCC‘s Committee on Yarn Dyeing Technology, the two-day program offered registrants ampleopportunity to co...
