| Research Abstract |
The air-flow inside and outside the pipe was analyzed during experiment and simulation, because they change according to air supply pressure and pipe combination. Further, speed was measured and behavior was observed for flying yarn, when the yarn was inserted in the pipe. As a result, to operate appropriately without damaging the yarn, the air-flow shouldn't cause rapid diffusion or deceleration, and the air drag should be kept at a constant on the yarn. The most efficient pressure results from the condition before the compressibility effect occurs. Even when the air drag is insufficient, the flying behavior can be improved, if the yarn is inserted by a feed device.
