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...
Cellulose/aromatic polysulfonamide (PSA) blended fibers with good flame-retardant, hydrophilic and mechanical properties were successfully prepared by dry-jet wet spinning technology with 1-butyl-3-methylimidazolium chloride ([BMIM]Cl) as solvent. The solution behaviors were studied using the polarized light microscopy (PLM) and rheology measurements. PLM images showed that both cellulose and PSA...
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...
