The Use of Polyacrylic Acid Sodium Salt (PAAS) in Textile Printing and Dyeing

November 10, 2026 admin No Comments

Sodium Polyacrylate (PAAS) is used in textile printing and dyeing primarily as a dispersant, thickener, and sizing/ adhesion agent, with its function highly dependent on molecular weight. Low-molecular-weight PAAS excels at dispersing dyes and preventing back-staining, while higher-molecular-weight grades serve as thickeners and binders. Primary Applications 1. Washing Off & Anti-Back-Staining (Low Molecular Weight) After…

The Working Principle of Polyacrylic Acid Sodium Salt (PAAS)

November 7, 2026 admin No Comments

Sodium polyacrylate (PAAS) works primarily through two mechanisms depending on its application: scale inhibition in water treatment and dispersion in particulate suspensions. Its effectiveness is fundamentally linked to its molecular weight and the density of its carboxylate groups. Scale Inhibition Mechanism In industrial water systems, PAAS prevents hard scale deposits (like calcium carbonate and calcium…
