Spinnable dopes for making oriented, shaped articles of lyotropic polysaccharide/thermally-consolidatable polymer blends |
摘要 |
Spinnable dopes containing fiber-forming polymers being at least about 55% and less than about 80% lyotropic polysaccharide and at least about 20 percent and less than about 45% thermally-consolidatable polymer and a process for making oriented, shaped articles of lyotropic polysaccharide/thermally-consolidatable polymer blends by orienting the dopes and removing the solvent.
