The invention relates to an industrial fabric and its use. The industrial fabric () comprises several machine direction (MD) yarns () and several cross machine direction (CMD) yarns (). The MD-yarns are twisted relative their longitudinal axis so that the twisted yams have sloped surfaces () at least on a web side surface (P) of the textile. The textile is usable in paper machine, pulp machine or filtering machine. 11. An industrial textile for supporting a fibre web in a processing machine , the textile () comprising:a web side surface (P), which is facing towards the fibre web to be processed during use of the industrial textile;a roll side surface (R), which is facing towards the processing machine during the use;{'b': '2', 'several machine direction (MD) yarns () and at least some of them have flat cross sections; and'}{'b': '3', 'several cross machine direction (CMD) yams ();'}characterized in that{'b': 1', '2', '2', '2, 'i': a,', 'b, 'the textile () is a woven fabric and comprises several machine direction yams (, ), which are twisted relative to their longitudinal axis;'}{'b': 2', '2', '2', '4, 'i': a,', 'b, 'and wherein the twisted flat machine direction yarns (, ) expose as slanted surfaces () at least on the web side surface (P).'}22. The textile as claimed in claim 1 , characterized in that all of the machine direction yarns () are twisted.3. The textile as claimed in or claim 1 , characterized in that{'b': 4', '2', '6', '1, 'each of the slanted surfaces () formed of the twisted flat machine direction yarns () appear as portions having shape of an outer surface of a segment of a truncated circular cone () at least on the web side surface (P) of the textile () when seen from the web side surface (P).'}4. The textile as claimed in claim 1 , characterized in that{'b': 1', '2', '2', '4', '2', '1', '4', '2', '1, 'i': a', 'b', 'a', 'b, 'the textile () comprises several adjacent first machine direction yarns () and second machine direction yarns () which are ...
