A constitutive theory is proposed to predict the stress-strain behavior of a twisted filament
yarn under extensive elongation from the structural parameters and constituent moduli. This
theory can predict the radial distributions of local stress and strain as well as the load-
elongation relation, if the initial distributions of the local apparent density and fiber direction
together with several elastic moduli of the parallel fiber bundle at any strain are known as
the elemental information. The underlying mathematics is developed so as to be closed
before a special assumption to specify the orientational structure of the yarn, such as the
cylindrical-helix model, the conical-helix model, etc., is put in force, and furthermore to be
free from the critical problem that most of the earlier theories have, i.e., the defect that an
approximation valid only for an infinitesimal deformation is assumed for a finite elongation.
