MEASUREMENT OF DYEING PROPERTIES AND CORRELATION WITH ORIENTATION IN NYLON YARN

Abstract

ABSTRACT Dyeing rate, equilibrium dye uptake and penetration rate studies have been carried out with anionic and dispersed acetate dyestuffs on a range of “66” nylon samples of various degrees of orientation. Differences in the appearance of dyed nylon fabrics produced by irregularities in orientation are shown to be primarily dependent on differences in dyeing rate. A routine method of assessing the magnitude of within package variations in orientation is described.
