In the printing process, what is added to the fabric to attach the pigment?

In the printing process, a viscose binding paste is crucial because it acts as a medium that helps to attach pigments to the fabric. This binding agent allows the dye or pigment to adhere properly and ensures that the colors remain vibrant and durable after the printing process. The viscose component is particularly effective due to its ability to create a cohesive bond with both the dye and the fabric, enhancing the overall quality and longevity of the printed design.

Other options do not fulfill this specific role in the same way. Water can act as a solvent in some printing techniques but does not provide a binding action necessary for adhesion. Varnish is typically used for finishing or protective purposes, rather than binding pigments to fabric. Wax is generally used in batik techniques to resist dye but does not serve the function of attaching pigments for printed designs. Therefore, the use of viscose binding paste is essential in achieving a successful and lasting print on textile materials.
