Abstract: A textile fabric employs a corrugated synthetic flat yarn having a plurality of filaments arranged in side-by-side relationship and being integral with adjacent filaments. The tape is corrugated tape woven or knitted with other yarns in a flat, substantially untwisted attitude. The tape is fabricated without fibrillation but controlled splitting may occur during subsequent fabric sewing or stitching operations. The fabric is particularly suited for use as geotextiles, woven intermediate bulk containers, woven explosive bags, and strapping (webbing).
