Cellulose/aromatic polysulfonamide (PSA) alloy fibers with good flame retardant properties were successfully prepared by changing the viscosity ratio of cellulose and PSA solutions. To reduce the content of PSA in the alloy fibers, cellulose and PSA with different molecular weight were adopted to prepare the alloy fibers. From the results of the limiting oxygen index(LOI) and the self-extinguishing...
1-Butyl-3-methylimidazolium chloride ([BMIM]Cl) was selected as co-solvent to dissolve cellulose and silk fibroin and the cellulose/silk fibroin blend fibers were fabricated with dry-jet wet spinning technology. The phase morphology of cellulose and silk fibroin in the blend fibers was studied by scanning electron microcopy and laser scanning confocal microscope. It is shown that the cellulose is...
The rheological behavior of cellulose and silk fibroin blend in 1-butyl-3-methylimidazolium chloride was studied. The data from the rheological results was analyzed to understand the microstructure of the blend solutions. The viscosity and dynamic modulus of the blend solution decreased with increasing ratio of silk fibroin. While comparing the experimental results with the calculated data from the...
