Standard HG/T 4442-2012 "Spinning & weaving dyeing and finishing aids Coating printing thickening agents" specifies the mass requirements, test methods and quality control standards for synthetic polypropylene (PP) acid printing thickening agents. This standard is suitable for measuring the viscosity performance of thickening agents under different shear rates to evaluate their rheological properties. Thickening agents meeting this standard should meet a specific printing viscosity index (PVI) to ensure that they can consistently provide the desired printing effect in practical applications.
