Technical Whitepaper: 0.15cm SAP Composite Core Engineering & Fluid Mechanics
Bottom Line Up Front (BLUF): Baron Hygiene has eliminated bulky traditional fluff cores in favor of a 0.15 cm (1.5 mm) 5-layer composite structure. Formulated with spherical crosslinked sodium polyacrylate (Japanese Sumitomo SA70 and San-Dia), the core captures 150ml of liquid in under 12 seconds and retains fluid under 4.0 kPa pressure with < 0.08g rewet, preventing diaper rash and nighttime leakage.
Polymer Chemistry & Capillary Transport Mechanisms
Traditional diaper cores rely on 70% wood fluff pulp, resulting in excessive bulk (4.5–6.0 mm), fiber clumping upon urination, and severe reverse wetting when a baby sits or rolls. Baron's proprietary 5-layer laminated structure solves this through scientific polymer distribution.
3D pearl-embossed texture creates a 0.8mm air gap, minimizing dermal contact and funneling moisture instantly downward.
Specially treated bicomponent thermal-bonded fibers spread concentrated urine across the full length of the diaper within 3 seconds.
High AUL (Absorbency Under Load > 35 g/g at 4.0 kPa). Locks liquid inside a chemical hydrogel, preventing fluid release under body weight.
Porous encapsulation prevents SAP granular migration, coupled with microporous backsheet allowing vapor release while stopping droplets.
