Measurement of Stress in Clothing: A Literature Review and Methods Selected,
Abstract
In a DCGEM-sponsored task to determine if alternative seam types could replace the commonly-used double lap seams in Canadian Forces (CF) clothing, the question was raised as to how strong seams have to be in clothing. In a 1952 study, Frederick at Natick, had stated that the seam strength, for the end uses he was considering should be 80% of the fabric strength. The recommendation arising from a DCGEM-sponsored task was that the criteria of 80% seam efficiency be revalidated because of the progress made in technology since Frederick's work, resulting in stronger, more durable sewing threads, seams and fabrics. This study was undertaken to find a technique to determine where maximum stresses in clothing, and thus, in seams, occur; to find a reliable method to measure these maximum stresses; and to determine the maximum stresses which would occur in the seams of various CF garments which presently have double lap seams. This paper reviews the literature for methods to determine where stresses occur in clothing, what stances cause maximum stress and how to measure these stresses. It describes various approaches tried and final selection of methods used to both qualitatively and quantitatively measure stress in clothing.
