摘要

The influence of pregrafting of cotton fabrics with mixed monomer on the dyeing kinetics of direct dyes was investigated. The results of this research show that the equilibrium absorption (a(e)) and activation energy (Delta E*) in the dyeing of grafted fabrics are smaller than those of ungrafted fabrics. The experimental results show that the value of the equilibrium absorption is smallest when the molar ratio of MAA/MAM (methacrylic acid/methylacryl amide) is 4/6. However, the rate constant (k')is larger for grafted fabrics than for ungrafted fabrics. No significant difference was observed between the structural diffusion resistance constant (n) of grafted and ungrafted fabrics. (C) 1997 John Wiley & Sons, Inc. [References: 14]
