| titleOfInvention | A kind of polyimides superfine fibre and preparation method thereof |
| abstract | The invention discloses a kind of polyimides superfine fibres and preparation method thereof: solvent dissolution is added in diamines under nitrogen protection; then dianhydride, which is added, makes the solid content 9%-20% of solution; 3-12 hours acquisition polyamic acid spinning solutions are reacted at 0-50 DEG C of temperature; polyamic acid spinning solution is subjected to spinning according to wet process or dry-wet spinning technique, gained polyamic acid precursor carries out imidizate using hot amidation or chemical imidization technique again.Polyimides superfine fibre monofilament linear density minimum prepared by the present invention can reach 0.153dtex, and raw material sources are extensive, at low cost, and spinning process is stablized, and industrialized production may be implemented. |
