喷气织机织物下机缩率的理论与实践

On the Theory and Practice of the Fabric Shrinkage off the Air Jet Weaving Machine

喷气织机采用气流引纬，其织造工艺为小开口大张力。根据测定上机张力约为有梭织机的二倍，同时由于采用专用工具落布，其落布长度为有梭织机的５～６倍。正因为其作应力与作用时间的差别，引起织物的三种变形的重新分配，从而导致织物下机缩率的差异。对这种差异进行理论分析，并提供某些纺织厂的实际数据以供参考。

The air jet weaving machine employs the air picking-up, its weaving technology consisting in small shedding and large tension. It is measured that the On-machine tension is twice that on the weaving machine with shuttles. On the other hand, due to the special tools used for taking off, the taking-off length is 5～6 times as much as that of its counterpart. It is for the differences in applied load and time that lead to the redistribution of the three deformations, which in turn brings about the variations of...
