Natural Cellulose Pulp/Paper TRIZ Cases

Associative polymers enhance retention and drainage performance in papermaking processes through optimized inverse emulsion polymerization.

A recording sheet uses water soluble divalent metal salts to control ink transfer and improve image dry time.

A wet-laid absorbent sheet combines pulp and synthetic fibers with an epihalohydrin/amine functional wet-strength resin to increase structural integrity.

A microparticle retention system uses high molecular weight polymer and inorganic components to improve paper formation.

A surface sizing composition deposits a continuous barrier layer on cellulose paper to enhance print quality and printer durability.

Dried low basis weight paper yields cellulose fibers that reinforce thermoplastic resin, balancing strength and impact resistance without trade-offs.

Sequential flocculant addition and controlled shearing produce shear-resistant filler flocs, maintaining sheet strength at high filler loadings.

A composite acrylamide copolymer coats filler particles to enhance affinity with pulp slurry and improve paper strength.

Dispersing particulate materials at fiber interstices within a wet-laid matrix increases shear strength while maintaining fluid permeability.

Cigarette paper bands with selective material application reduce gas diffusion to ensure self-extinguishment.

Synergistic polymer and polyvinylamine combination enhances solids retention in papermaking slurries.

Sizing compositions with calcium carbonate and polyvinyl alcohol improve inkjet print density while reducing color bleed.
