Paper/Cardboard TRIZ Cases
- Fibril Cellulose Dewatering via pH Adjustment
Lowering pH converts dissociated acid moieties to reduce water retention, enabling efficient pressure filtration of fibril cellulose.
- Foam Formed Cellulosic Composite Web Production
Foam forming creates porous thermoformable webs from cellulosic fibres and thermoplastics for compression moulding.
- Semi-Batch Colloidal Silica Production for Low Viscosity
A semi-batch process produces aqueous colloidal silica with 16-18% solids and low viscosity.
- Multi-ply Tissue Products with Improved Cross-Machine Direction Properties
Through-air drying of a multi-ply tissue web imparts cross-machine direction strain, balancing CD tensile strength and softness without creping.
- In-line Precipitated Calcium Carbonate Hybrid Material for Paperboard
Microfibrillated cellulose adsorbs precipitated calcium carbonate into a hybrid ply, improving whiteness and elastic modulus without reducing tensile strength.
- Cationic Polymer Filler Retention in Wood Free Pulp
Adding a cationic polymer to mechanical pulp before mixing improves first pass ash retention while maintaining sheet bulk and stiffness.
- Flame-blocking nonwoven fabric with low-shrinkage fibers
Composite nonwoven fabric uses low-shrinkage non-melting fibers and high LOI thermoplastic fibers to prevent fire spread without losing structural integrity.
- Microfibrillated Cellulose Foams via Salt Templating
Salt particle templating controls porosity in dried microfibrillated cellulose foams, eliminating costly freeze drying.
- Self-Mounting Collapsible Tray Corner Pillar Reinforcement
Extending corner pillar segments along end walls resolves compressive strength trade-offs while maintaining compact folded dimensions.
- Hemicellulose Polymer Dispersion for Coating Barrier Performance
Polymerizing hemicellulose with styrene and alkyl acrylates via redox initiation yields a dispersion that improves water vapor transmission rates.
