<p>Aramid monofilament (20) characterized by the following relations: 1,7 « Ti « 260; 40 « D « 480; T » 170 - D/3; Mi » 2000; Ti being the titer in tex, D being the diameter in νm, T being the tenacity in cN/tex, Mi being the initial modulus in cN/tex, for this monofilament. Method for obtaining this monofilament (2) in which a solution (2) of aromatic polyamides (5) is extruded in a die (9), the jet is stretched in a layer of non-coagulating fluid (13) and the stretched liquid vein is put into a coagulating medium (19). Assemblies of these monofilaments. Articles strengthened by these monofilaments or these assemblies, such articles being for example tyre treads.</p> |
