Personal Care TRIZ Cases
- Fluid-Entangled Laminate Webs with Hollow Projections
Pressurized fluid jets entangle fibers into hollow projections, resolving the trade-off between structural integrity and skin softness in absorbent materials.
- Apertured Protuberance Film for Absorbent Articles
An integrated film layer with apertured protuberances distributes fluid while maintaining structural integrity under pressure.
- Backsheet Design for Distinct Print Visibility
A backsheet design uses a printed inner film layer beneath a thin outer nonwoven layer to create a cohesive aesthetic appearance.
- Absorbent Core Channel Stability via High Viscosity Adhesive Bonding
High viscosity rubber adhesive bonds core wraps into stable channels, preventing wet-state collapse and leakage while maintaining fluid distribution.
- Water-absorbing sheet with optimized DRC index for rapid absorption
A water-absorbing sheet uses a particulate agent with a specific DRC index to achieve rapid liquid uptake.
- Absorbent Article Top Sheet Protrusion and Opening Pattern
Zigzag arrangement of protruding, embossed, and opening parts reduces skin contact area and prevents surface liquid residue.
- 3D Sheet Material Minimizing Skin Contact in Absorbent Articles
Embossed 3D sheet material minimizes skin contact and rewet by creating liquid channels that enhance fluid absorption and distribution.
- Layered Nonwoven Substrates for Wet Wipe Softness and Strength
Segmented nonwoven substrates balance skin gentleness with wet strength through composite layering of soft outer and strong inner fibers.
- Gradient Nonwoven Topsheets for Absorbent Articles
Gradient hydrophilicity in a nonwoven topsheet prevents rewet while maintaining rapid fluid acquisition speed.
