Abstract (en)

Cut-resistant fibres, containing (A) a filler with a Mohs hardness of 3 or more and (B) a fibre-forming aromatic polyamide which is soluble in polar aprotic organic solvents and contains units of formulae -OC-Ar1-CO-NH-Ar2-NH- (I), -OC-Ar1-CO-NH--Ar3-NH- (II) and optionally -OC-Ar1-CO-NH-Ar3a (IIa), in which all Ar groups = mono- or poly-nuclear arylene with free valencies in the para- or meta- position or in corresponding parallel, coaxial or angled positions, and in which Ar2, Ar3 and optionally Ar3a may be different from one another in each case; the corresponding monomers being selected to give a polyamide which is soluble as above, preferably to give isotropic solutions. Also claimed is yarn containing these fibres.
