Thickeners are high molecular weight chemicals that give thick pastes in water and are utilized in textile printing. These give the printing paste stickiness and plasticity, allowing it to be applied to a fabric surface without spreading and keep the pattern outlines even under strong pressure. Their primary role is to keep or adhere dye particles in the desired location on the fabric until the dye transfer and fixing are complete. Because the printing paste is applied by squeegee pressure to a roller or a screen, its viscosity must be high enough to avoid quick diffusion or flushing of the colour through the fabric, which would result in the poor print definition.
