Diagnose sodium alginate printing defects by separating paste preparation, screen or transfer behavior, fixation and wash-off<\/strong>. First compare the failed batch with an approved reference for viscosity, hydration, filtration, pH, additives and holding time; then change one variable at a time to avoid masking the real cause.<\/p>\n\n\n\n

Use the table below for triage, then follow the symptom-specific checks in this guide. If the defect began with a new raw-material lot, retain paste and fabric samples and compare the supplier certificate with incoming QC data for textile-grade sodium alginate<\/a>.<\/p>\n\n\n\n
