Molecular miscible blend of aromatic polyamide and amorphous polymer, preparing method thereof, aromatic polyamide blend fiber using the same and dyeing method of the polyamide blend fiber
Molecular miscible blend of aromatic polyamide and amorphous polymer, preparing method thereof, aromatic polyamide blend fiber using the same and dyeing method of the polyamide blend fiber
The invention, and the para-aromatic polyamide polymer and a secret polymer of the stability of the high crystalline is uniformly mixed with a molecule having an optical anisotropy molecular miscibility of aromatic polyamide blend solution and aromatic obtained from the manufacturing method and which it under normal pressure and polyamide blend fibers to a method of dyeing these fibers. ; Molecular miscible blend solution of the present invention, the aromatic polyamide and the amorphous polymer according to the, following structural formula and the aromatic polyamide polymer comprising a repeating unit represented by (Ι), poly of the aromatic polyamide from 5 to 100% by weight polyvinylpyrrolidone is dissolved in a polar organic solvent the presence of an inorganic salt is characterized in that the formation of the molecular miscible blend solution: ; ..... (Ⅰ) ; Aromatic polyamides, non-crystalline polymers, the molecular miscible, blends, dye
