| Abstract | ||
| igment printing is an ancient and user-friendly method for creating printed fabrics, offering advantages such as near-final print ease, quality prints, applicability to various fibers or mixtures, and the ability to avoid washing processes after fixation. Insoluble pigments are used in finely dispersed forms, and film-forming binders are used to fix these pigments to the substrate. The choice of binders depends on the final fastness requirements and cost requirements of the process. Paint binders are latex polymer resins that form a three-dimensional film on the fiber's surface, containing the dispersion of textile pigment and adhering it to the substrate. They can be classified into reactive and nonreactive types. Synthetic thickeners, such as acrylic polymers, are high molecular weight polymers containing an acidic monomer and are used in pigment printing and printing with reactive, acid, and direct dyes. Synthesis techniques for producing printing thickeners include emulsion polymerization, low polymerization temperatures, higher molecular weight polymers, and high rates of polymerization. Understanding the rheological behavior of aqueous-based synthetic thickeners is crucial for understanding their flow behavior and mechanism of viscosity development. Newtonian fluids have constant viscosity at all shear rates under constant temperature and pressures, while non-Newtonian fluids have non-linear flow curves. Understanding the viscosity/shear relationship is crucial for rheological characterization and understanding non-Newtonian behavior. | ||
