時間の変動を生じやすくする。(Conventional technology) Proper operation of pneumatic looms, which thread the weft yarn through the shed by means of air jets blown from nozzles appropriately placed upstream, inside, and downstream of the shed, is primarily dependent on the physical properties of the yarn. Depends on the constancy of the parameters. In fact, any variation in such parameters will affect the "flight" of the yarn, especially in the weft.
Make time fluctuations more likely.

。Assuming that an initial short "flight" results in an optimal setting, any variation in the physical parameters of the yarn will lengthen the cycle time and thus also lead to machine stoppage. If the cycle time is set to avoid machine stoppage under these conditions (in effect by increasing the supply pressure of the main nozzle right and/or the auxiliary nozzle), the yarn conditions allow for even shorter flight times and It also increases the consumption and causes defects to appear in the woven fabric.
