Effect of Water Repellent Agent on Migration of Disperse Dyes

摘要

In order to investigate the diffusion of disperse dye between substrates and hydrophobic auxiliaries, two different kinds and dosages of water repellent agents were applied to conventional and microdenier polyester by measuring their K/S value, color difference (△E) and extracted absorbance. The results illustrated that irrespective of the kind or of the dosage of water repellent agents, dye migration increased upon the employment of water repellent, and heat treatment will accelerate the dye migration process.
