Abstract

Loom configurations and methods for efficiently manufacturing unique spiral-shaped fabrics. The loom introducing two weft yarn segments in the form of a continuous loop in each shed may be configured with one or two weft needles and is equipped with a knitting system to form a knitted selvedge along the outside circumference of the fabric. The knitted edge is used as reference to form weft yarn loops of different lengths. The opposite weft yarn loops are permanently secured around selected warp yarns. Alternatively intermediate length weft yarn loops may be created where the extremity of the loop is not bound to any warp yarn. Fiber architectures may be designed and woven which exhibit uniform fiber volume across the width of the fabric. Fiber architectures with greater fiber volume along the outside circumference of the fabric may also be prepared.
