A fiber having increased cut resistance is made from an isotropic polymer and a hard filler having an average particle size in the range of about 0.25 to about 10 microns and having a Mohs Hardness Value greater than about 3. The filler is included in an amount of at least about 0.1 % by weight. The preferred isotropic polymer is poly(ethylene terephthalate). The preferred filler is calcined alumina.

On fabrique une fibre dont la résistance à la coupure est augmentée, à partir d'un polymère isotrope et d'une charge dure ayant une granulométrie moyenne de l'ordre d'environ 0,25 à environ 10 microns et une dureté supérieure à environ 3 sur l'échelle Mohs. La charge introduite représente au moins environ 0,1 % en poids. Le polymère isotrope préféré est le poly(éthylène téréphtalate). La charge préférée est l'alumine calcinée.
