What is it about?
Performing the crease recovery finishing of cotton before the pigment printing. In this study, sulphonic acid-based zwitterions are evaluated as an alternative catalyst system for the crease recovery finishing, using dimethyloldihydroxyethylene urea, of cotton fabric prior to pigment printing

Why is it important?
Crease recovery finishing using a conventional catalyst, magnesium chloride, induces loss of pigment print definition attributed to the electrolytic thinning of polyacrylate-based synthetic thickener. However, such electrolytic thinning can be prevented by using aminomethane- or aminoethane-sulphonic acid.
Perspectives
Performing the crease recovery finishing prior the pigment printing provides an option to finish ans stock the fabric. When the pigment printing is desired, the process can be performed promptly. A combined catalyst with ammonium chloride is identified as an alternative catalyst for crease recovery finishing prior to pigment printing. The properties of finish and pigment print evaluated using this catalyst are improved without the loss of print definition.
