Classification of Fabric Weave Patterns
In the simplest weaving arrangement, alternate warp yarns are over or under the shuttle as it moves in one direction and the warp yarn positions are reversed for the return stroke of the shuttle. This weave can be made on a loom with only two harnesses. In other arrangements, several warp yarns may be moved upward or downward together, or several filling picks may take place before the warp yarns change position.
