1. Polypropylene fibre which is difficult to ignite and has an ethylene content of 0 to at most 10% by weight, characterised in that it contains 0.5 to 10% by weight of 1,3,5-tris-(2,3-dibromopropyl)-2,4,6-trioxo- hexahydrotriazine and 0.15 to 3.5% by weitht of Sb2 O3 , and per mol of the triazine compounds 0.05 to 1.5 mols of an organic tin compound of the general formula see diagramm : EP0005496,P6,F1 in which R1 and R2 , which can be identical or different, each denote an alkyl or cycloalkyl radical and X and Y, which can be identical or different, each denote an alkyl or cycloalkyl radical, the radical of an organic acid, which can optionally contain a further esterified carboxyl group, the radical of an inorganic acid or a thioalkyl group, which can optionally carry a carboxyl group esterified with aliphatic alcohols, or X and Y together denote oxygen, the radical of a dibasic inorganic or organic acid or a radical of the formula -S-(CH2 )n -COO- in which n is defined as the integer 1 or 2, if appropriate in addition to the customary lubricants, pigments and/or stabilisers. |
