Precipitation kinetics of cellulose in the Lyocell spinning process
The average concentration of N-methylmorpholine-N-oxide (NMMO) in the running Lyocell filament was measured in the coagulation process by which the precipitation kinetics of cellulose in the Lyocell process was studied. It was found that there are two diffusion regimes in the coagulation process of cellulose in the Lyocell process. The fast regime is completed within 1 s, causing formation of...

Arrangement of cellulose microfibrils in the wheat straw cell wall
The arrangement of cellulose microfibrils in the cell wall from different tissues of wheat straw was investigated mainly using atomic force microscope (AFM). It was revealed that cellulose microfibrillar crystals arrange randomly in the parenchyma cell walls and are ordered quite well longitudinal to the fiber axis in the epidermal fibers. The microfibrillar crystals are about 20 nm in diamet...

Construction of Small-Diameter Vascular Graft by Shape-Memory and Self-Rolling Bacterial Cellulose Membrane
关键字：Bacterial Cellulose Membrane
Bacterial cellulose (BC) membranes with shape-memory properties allow the
rapid preparation of artificial small-diameter blood vessels when combined
with microfluidics-based patterning with multiple types of cells. Lyophilization
of a wet multilayered rolled BC tube endows it with memory to recover
its tubular shape after unrolling. The unrolling of the BC tube yields a flat
membr...

Fabrication of Superhydrophobic Cellulose-Based Materials through a Solution-Immersion Process,
关键字：Superhydrophobic, Cellulose, Solution-Immersion Process
An industrial waterproof reagent [(potassium methyl siliconate) (PMS)] was used for fabricating a superhydrophobic surface on a cellulose-based material (cotton fabric or paper) through a solution-immersion method. This method involves a hydrogen bond assembly and a polycondensation process. The silanol, which was formed by a reaction
of PMS aqueous solution with CO2, was assembled on th...
