The analysis of a series of controlled experiments using sets of fabrics of nominally the same woven construction made of different fibers led to the conclusion that, in general, a crease or wrinkle in a fabric can involve a permanent deformation of filaments, a deformation of the yarn caused by interfilament friction, and a structural distortion of the fabric. The main objective of the previous papers in this series was to establish the principal parameters which affect the filament and yarn bending recovery and the resistance of woven fabrics to undergo permanent distortion in construction when subjected to bending or wrinkling deformations. We found that the fiber properties which affect the recovery of single filaments are the yield strain in compression and the ratio of the compressional to tensile longitudinal moduli. Both these quantities are functions of draw ratio and thermal history of the fiber. The fiber properties which affect the recovery characteristics of yarns and fabrics are friction coefficient, modulus of elasticity, and settability. Previous articles of this series dealt with the development of a fabric wrinkle-recovery equation and its verification. In this study we present examples illustrating the application of the developed equation to analyze the effects of fabric construction and severity and time of application of wrinkling conditions.
