A Classification of Shedding Methods.

Monodirectional and bidirectional shedding operations are critical for two dimensional and three dimensional weaving, respectively. These two classes of shedding operation comprise seven separate categories, which are useful for reference. Monodirectional shedding in which the warp yarn ends are displaced only in the fabric thickness dire..

Shed Geometry Measuring Process.

Shed geometry affects warp loading, which determines weaving warp and loom running behavior. Although loom design largely determines shed geometry, the weaving mill can modify shed geometry through adjustments on the rear shed. Because the determination of a complete shed geometry is impossible at the mill, researchers developed a measuri..
