Abstract
The study compares alternative seams with the double-lapped seam made in typical Canadian Forces fabrics in order to determine if a seam, other than the double-lapped seam, would be equally serviceable. An acceptable level of seam efficiency had been arbitrarily set at 80% by researchers in the fifties, and was used here. The double-lapped seam attained at least this level in all three fabrics used. Only one of the four alternative seam types evaluated in only one of the fabrics used reached this level. It was recommended that the criterion of 80% seam efficiency be revalidated because of the progress made since the fifties in the technology of sewing threads, seams and fabrics to make them all stronger and more durable.
