Single Layer: One set of MD + CD yarns, best drainage (500-800 CFM), lowest FSI (50-80), suitable for low-speed heavy-weight grades.
Double Layer: Two sets of CD yarns, FSI 80-120, CFM 400-650, the mid-speed workhorse.
Triple Layer: Separate top (fine) and bottom (wear-resistant) weaves bonded by binder yarns, FSI 130-200+, CFM 250-500, typical life 60-150 days.
SSB (Sheet Support Binder): Premium triple-layer variant with optimized binder design — 30-50% longer life, 5-15% better FPR, 50-80% less sheet marking.
