Subsurface stain routing and optical concealment architecture for absorbent products
A multilayer stain-management architecture for absorbent products that separates fluid acquisition from stain visibility using engineered pore geometry, gradient transport, subsurface retention, and optical scattering—reducing post-use stain appearance without sacrificing acquisition, dryness, comfort, or leak protection.
Overview
Valor Infrastructure Holdings proposes a multilayer stain-management architecture for absorbent products such as sanitary pads. The design separates fluid acquisition from stain visibility through three coordinated functional regions: a rapid-acquisition upper layer that moves fluid away from the visible plane, a directional transport region that favors downward flow while limiting lateral surface spread, and a subsurface retention region that keeps color-bearing fluid below the primary viewing surface. Engineered pore geometry, texture, scattering structures, and optical treatments then reduce perceived stain intensity without requiring complete chemical decolorization.
The key design objective is dual-function geometry: promote fluid transport while disrupting the return optical path. This creates a practical path to improved post-use appearance while maintaining acquisition, dryness, comfort, and leak protection.
Technical specifications
The architecture combines established physical mechanisms—capillary transport, pore-size gradients, subsurface retention, optical scattering, and surface texturing—using materials already common to nonwoven and absorbent-product design.
Key features:
- Rapid-acquisition upper layer moves fluid away from the visible surface
- Directional/gradient transport region limits lateral spread and favors downward flow
- Subsurface retention region keeps color-bearing fluid below the viewing surface
- Optical scattering and surface texturing disrupt the return optical path
- No reliance on complete chemical decolorization of blood or other fluids
Technology readiness level
The concept is in early-stage development. Valor proposes a gated 6–12 month validation program. The first phase defines a baseline pad architecture and measurable targets for stain visibility, acquisition time, rewet, leakage, comfort-related thickness, and compression performance. Next, commercially available nonwoven, gradient-transport, textured, and optical-scattering materials are screened to build multilayer coupon architectures with minimal construction changes. Each architecture is tested with a realistic fluid simulant or blood-based method, quantifying visible stain area, contrast, transport depth, lateral spread, rewet, and compression stability. The best-performing configuration is then integrated into pad-format prototypes and re-tested against baseline under simulated wear and compression. The final phase optimizes manufacturability and material cost to produce a licensing-ready architecture.
