PURPOSE: To obtain a knotless net having stabilized crossing through parts without causing yarn slippage and mesh breakage by crossing two three-twisted strands emerging from different directions under specific conditions.

CONSTITUTION: Three-twisted strands (2a), (2b) and (2c) and (3a), (3b) and (3c) are crossed. In the process, the strands (2a), (2b) and (3a) and (3b) are crossed in the same directions as the forward direction. At this time, the strands (2a) and (3a) are crossed so as to mutually pass through twist of the opposite. Furthermore, the strands (2c) and (3c) detour so as to respectively embrace the through crossing parts from the outside. Thereby, the strands are crossed in direction different from the forward direction so as to respectively and mutually intertwist the strands (2a), (2b) and (3c) with the strands (3a), (3b) and (2c) after crossing the two three-twisted strands.
