Ethylenediamine tetra(methylene phosphonic) acid as a Carrier for the Disperse Dye Palanil Violet 3B

Ethylenediamine tetra(methylene phosphonic) acid in an acidic medium is able to attach itself to the dye molecules while being adsorbed by polyester fibres. Hydrogen bonds as well as electrostatic attractive forces are involved in both processes, leading to an increased dyeing rate
