HI Technical Guides for Textile Printing Chemicals
Explore practical guidance on product selection, applications, testing and supplier evaluation for CMC, CMS, sodium alginate, digital printing paste and textile printing thickeners.
CMC Degree of Substitution (DS): How It Affects Salt Tolerance, Solubility and Textile Printing Performance
Degree of substitution is one of the most important structural specifications of CMC. Higher DS can improve water compatibility and electrolyte tolerance in suitable grades, but viscosity and textile printing performance also depend on molecular weight, substitution uniformity, purity, formulation and test conditions.
CMC Purity, Sodium Chloride and Active Content: What Textile Buyers Should Compare
CMC purity should not be evaluated from one percentage alone. Textile buyers should separately compare active CMC, sodium chloride, moisture, sodium glycolate where relevant, DS, viscosity method and actual printing performance.
How Water Hardness Affects CMC Hydration and Viscosity in Textile Printing
Water hardness can change how CMC hydrates, expands and builds viscosity. Calcium and magnesium can behave differently from sodium salts, and hard water does not always cause the same viscosity response. Plant water should therefore be tested as part of the actual textile printing formulation.
