3—THE FINITE-DEFORMATION THEORY OF PLAIN-WEAVE FABRICS PART I: THE BIAXIAL-DEFORMATION THEORY

Theories of the biaxial tensile properties, the uniaxial tensile properties, and the shear-deformation properties of plain-weave fabrics are presented in a general form, a simplified stereo-model of the structure of plain-weave fabrics being used throughout these theories.

In the first part of this series, the biaxial tensile-deformation theory is presented with the aid of the model, and the forces required to stretch the fabric along the warp and weft directions at the same time are theoretically calculated from the properties of yarns and from the structure of the fabrics. In this biaxial theory, both warp and weft yarns are assumed to be perfectly flexible, and the forces caused by yarn-bending are ignored. The compressibility of the yarn under the action of a lateral compressive force is also introduced into the theory, and it is shown that the compressive properties of yarns have a great influence on the tensile properties of the fabrics.     

Proposals towards improving worsted processing. Part 1: identification and theoretical evaluation of possibilities for optimising the drawing sequence

The possibility of improving the evenness of worsted slivers, rovings and yarns by the simple expedient of optimising the drawing sequence is examined theoretically. The drawing sequences commonly used by mills have generally been established by trial-and-error methods, using the knowledge that the evenness of any material can be contained or improved by the practice of doubling, and made worse by drafting, but with little or no application of scientific method. A simple mathematical model of the worsted processing sequence, which has proved to be a powerful tool for both problem solving and in research, is used to investigate if and how yarn quality might be improved by simple adjustments to the number of doublings and the draft ratios used. The outcome of these theoretical studies predicts that some improvement in the quality (evenness) of yarn can be achieved, and raises questions about the appropriateness of the doublings and the draft ratios commonly used.
