Distribution of Yarn Breakage of Running Yarn.

A Statistical Analysis of Yarn Breakage on Spinning Frame

The problem of yarn breakage during spinning is quite serious, but it is difficult to predict the number of yarn breakages, because the tension and strength of the yarn always vary. The author has used simple mathematical models of the variation of the tension and the strength of the yarn, and calculated the probability of yarn breakages. The result has shown that the variation of the yarn stre...

ABS-YARN: A Formal Framework for Modeling Hadoop YARN Clusters

In cloud computing, software which does not flexibly adapt to deployment decisions either wastes operational resources or requires reengineering, both of which may significantly increase costs. However, this could be avoided by analyzing deployment decisions already during the design phase of the software development. Real-Time ABS is a formal language for executable modeling of deployed virtua...

Simulating Yarn-based Cloth

Cloth is an important material to model and simulate correctly, both in computer graphics and other industrial applications. The commonly used models for cloth in computer graphics typically approximate the cloth as an elastic sheet with linear isotropic behavior inspired by the construction of woven fabrics. However, they do a poor job of predicting the behavior of knits, which are driven by t...

Distribution of Power Requirements during Yarn Winding in Ring Spinning

Analysis of Yarn Bending Behaviour

This paper addresses the bending behaviour of individual multi-filament yarns for use in textile forming analyses. Yarn specimens deform nonlinearly under their own weight in a cantilever configuration. A relation between the applied moment and the resulting curvature is established. Numerical simulations are performed to establish the contribution of shear rigidity to the deflection.
