Abstract:

In order to prepare fibers with flame retardant property and good hygroscopicity, N-methylmorpholine-N-oxide monohydrate (NMMO·H2O) was used as co-solvent to dissolve aromatic polysulfonamide (PSA) and cellulose, and the PSA/cellulose blend fibers were fabricated by dry-jet wet spinning. The structure and properties of spinning solution and blended fibers were characterized and analyzed. It is found that NMMO·H2O can dissolve PSA well, and the spinning solution is homogeneous and stable. An analogous ″sheath-core″ morphology is observed in the fibers as PSA distributed more in the sheath domain. The flame retardant property, moisture absorption ability and the mechanical property of the PSA/cellulose blended fibers are good. When the cellulose content is 30% in the blend fiber, the blend fibers still meet the requirement of flame retardant fiber standards. The tensile strength of the blend fiber is up to 2.08 cN/dtex, which shows a good tensile strength without post treatment. The moisture regain of PSA/cellulose fibers is up to 8%, and the dyeability is also improved.

Key words: aromatic polysulfonamide, cellulose, N-methylmorpholine-N-oxide monohydrate, flame retardant fiber
