The properties of complex thickeners based on polyurethane and natural polymers used in pigment printing are investigated. The optimum ratio of the components is determined. Optical, scanning electron, and atomic force microscopy show that the use of polyurethane in such thickeners increases the softness of the printed materials.
An assessment has been made of the effectiveness of use of aqueous polyurethane dispersions as binders in pigment printing on textile materials based on blends of natural and chemical fibres. The composition of the composite thickening agent has been formulated for optimizing their use.
