HI Guides techniques sur les produits chimiques destinés à l'impression textile
Découvrez des conseils pratiques sur le choix des produits, leurs applications, les essais et l'évaluation des fournisseurs pour les CMC, les CMS, l'alginate de sodium, les pâtes d'impression numérique et les épaississants pour l'impression textile.
How Water Hardness and Calcium Ions Affect Sodium Alginate Printing Paste
Calcium in hard water can change sodium alginate from a normal viscous solution toward stronger chain association, gel particles or poorly soluble calcium alginate. Mills should compare plant water with controlled soft water and validate the complete printing, steaming and washing route.
How Alkali Addition Timing Affects Sodium Alginate Reactive Printing Paste Stability
Alkali is required for reactive dye fixation, but adding it too early can expose reactive dye to alkaline water before printing and steaming. This can shorten the usable paste window through dye hydrolysis and, depending on the formula, rheological changes.
Sodium Alginate Wash-Off Residue: Why Reactive Printed Fabric Can Feel Harsh After Washing
Properly washed sodium alginate should normally leave little permanent thickener film. When reactive printed fabric feels harsh after washing, investigate incomplete wash-off, calcium alginate, residual salts/alkali, hydrolyzed dye and excessive paste deposit before changing alginate grade.
Sodium Alginate Concentration vs. Paste Viscosity: How to Build a Working Curve for Your Mill
Sodium alginate concentration and viscosity are not linearly proportional. Each mill should build a controlled working curve using the actual alginate grade, water, hydration method, temperature and viscosity test, then confirm the useful concentration through printing, steaming and washing.
Rotary Screen vs. Flat Screen Printing: How Thickener Rheology Requirements Change
Flat and rotary screen printing use the same basic transfer principle but expose printing paste to different shear and residence histories. The correct thickener should therefore be selected by low-shear body, high-shear flow, recovery, elasticity and machine stability rather than viscosity alone.
