The dirt-repellent monofilament with a toughness of at least 36 cN/tex and an extension of under 44 % has a soiling index AI > 2 after five soiling and cleaning cycles. To manufacture the dirt- repellent monofilaments, a copolymer with a melting point of 255 to 275 ° C and consisting of alkenes and monofilament is added to a polymer melt of polyethylene terephthalate before extrusion. The dirt-repellent monofilament is advantageously used in the manufacture of cleaning filters for the dry section of a paper machine, i.e. paper machine fabric filters. It may also be used to produce fabrics for general use as technical fabrics which have to be cleaned in difficult conditions.
