Leakage & Displacement Risks from Product Structure Design

2026-03-04

Poor structural design leads to side/ rear leaks, undermining security, and may increase local friction due to improper frequent adjustment.

Parameterized Evidence:
Size-Structure Compatibility: For regular-length pads (240mm-280mm), the height of leak-guard cuffs​ should be no less than 8mm. The elastic bands should use 3D embossing technology​ (not just printing) with a rebound resilience >85% (per ASTM D2594) to ensure dynamic fit.
Absorbent Core Construction: The transfer layer's​ longitudinal wicking time should be <3 seconds (GB/T 24218.8). The absorbent core​ should be a continuous, multi-layered composite with gradient mixing of fluff pulp and SAP to prevent core collapse and liquid rewet.
Adhesive Performance: The initial tack of the backing adhesive (on standard cotton fabric) should be within 2.5-4.5 N/25mm (referencing GB/T 2792). Tack that is too low causes shifting, while too high may damage clothing fibers.
