In this article, a set of theoretical relations among yarn count, twist, and diameter is derived based on a simplified mechanics of fibre compression. It is found that the basic quantity th...

Owing to twisting of filament fiber bundle, the structure and consequently various parameters and properties of a fiber bundle are changed. The aim of the work is to verify the effect of multifilament yarn twist (or twist coefficient) on selected mec

In this work, a micromechanical model of tensile behavior of fibrous composites was formulated by taking into account of the stress-strain behavior of fiber and matrix, the directional arrangement of fibers in the composites, and the relative space o

The aim of this research is to predict the yarn specific stress from fiber specific stress and fiber stress utilisation. In this paper a new approach is introduced to predict the specific stress-strain curves of cotton carded and combed yarns. The fo

In this article, the influence of tensile tester gage length on ring, rotor and air-jet spun yarns tenacity and its coefficient of variation have been investigated. A statistical model has been presented that correlates yarn tenacity and coefficient

In this work, an attempt is made to create theoretical models on tensile behavior of staple fiber yarns and verify them with experimental results. While the first part of this work deals with model development, the second part reports on model valida

The theoretical models of tensile behavior of staple fiber yarns derived in Part I of this work are compared and validated with experimental results. It is observed that the stress–strain curve of yarn always lies under the stress–strain curve of

An attempt is made here to verify and validate the probabilistic models of yarn hairiness reported in Part I of this work. It is shown that the double exponential model of yarn hairiness corresponds more close to the experimental results than the sin
