Pulp Properties Modification TRIZ Cases
- Fluff Pulp Production Without Bleaching
Removing bleaching steps reduces chemical consumption and energy usage while maintaining absorption time between 2 and 4 seconds.
- Particulate Grinding Medium for Microfibrillated Cellulose
High-density ceramic particles with controlled friction reduce energy input while enhancing burst strength in microfibrillated cellulose.
- Hemp Microfiber Aerogel for Superelastic Thermal Insulation
Freeze-drying hemp microfibers yields superelastic aerogels that resist structural collapse while maintaining 0.0215 W/mK thermal insulation.
- Modified Cellulosic Fibers Reduce Hydrogen Bonding for Tissue Softness
Modified cellulosic fibers react with cyanuric halides to reduce hydrogen bonding, increasing tissue bulk and softness without compromising tensile strength.
- Press Drying Mechanical Pulp Web With Overpressure And Dry Strength Additives
A press drying process subjects mechanical pulp webs to heat and overpressure above 40 kPa alongside dry strength additives.
- Fine Cellulose Fiber Production via Ionic Liquid Fibrillation
A fibrillation solution containing an aprotic solvent and aldehyde cleaves cellulose hydrogen bonds to produce nanosized fibers without mechanical crushing.
- Method for manufacturing intermediate product for conversion into microfibrillated cellulose
Carboxymethylcellulose intermediate product enables efficient conversion into microfibrillated cellulose with limited energy input.
