The elasticity of silk woven fabrics is formed by the twist release of hard twist on weft yarn.

全真丝纬向弹力机织物的弹力主要利用强捻纬线的捻度释放来形成。

The skewness or bending of Weft yarn is unavoidable in finishing process of printing and dyeing.

织物在印染过程中，纬纱歪斜或弯曲是不可避免的。

The AIT provides a simulation of the welt insertion and measures the speed and speed variation of the weft yarn as it is inserted.

AIT能模拟引纬过程，并且可以测试在引纬过程中纬纱的速度和速度的变化。
