摘要 |
The present invention provides an aromatic polyamide bristle exhibiting excellent chemical resistance to acid, alkali, etc., and good mechanical properties such as rigidity, strength and modulus and heat-resistance, suitable for industrial applications such as tension member, fishing line and catheter, having a single fiber fineness of 10 to 200 denier, a flatness of 3 or below and mechanical properties characterized by a tensile strength of 15 g/de or above, an elongation at break of 4.0% or below and an initial modulus of 500 g/de or above and formed from an optically isotropic solution. |
