Artificial Filaments From Cellulose Solutions TRIZ Cases

Incorporating solid phosphorus particles into viscose spinning solutions creates durable regenerated cellulose fibers.

Multi-step water jet treatment bonds cellulose fibers in Lyocell webs, resolving strength deficits at low area weights while cutting energy use.

Ionic liquid spinning resolves the tensile strength versus elongation trade-off, delivering at least 80 J/g working capacity for tire cord applications.

Enzymatic synthesis of alpha-1,3-glucan replaces mechanical shortening, reducing raw material loss during lyocell fiber production.

Pressing undried fiber tows establishes natural crimp patterns, resolving the trade-off between process simplicity and post-processing quality.

A tetraalkylammonium acetate and aprotic polar solvent system dissolves cellulose uniformly at room temperature without pretreatment.

Adjusted air gap spinning parameters resolve wet fibrillation in lyocell fibers while maintaining high strength and dimensional stability.

A hydroentanglement process bonds cellulose fibers into a stable web without intermediate drying steps.

Replacing liquid ammonia with gaseous ammonia reduces chemical consumption and reaction time while eliminating toxic carbon disulfide use.
