Grey Relational Analysis to Determine the Optimum process parameters for Open-end Spinning Yarns

Abstract

This article focuses on an approach based on the Taguchi method with grey relational analysis for optimizing the process parameters for open-end spun yarns with multiple performance characteristics. A grey relational grade obtained from the grey relational analysis is used to optimize the process parameters.

Regression Model for the Bagging Fatigue of Knitted Fabrics Produced from Viscose/Polyester Blended Rotor Yarns

Abstract

The aim of this work was to predict the bagging fatigue percentage of knitted fabrics produced from viscose/polyester blended rotor yarns using blend ratios and structural cell stitch lengths as predictor variables. A simplex lattice design was used to determine the combinations of blend ratios of the fiber types.

Determination of Handle of Knitted Fabric using an Objective Measuring Technique

Abstract


An objective approach to assess the handle of fabrics has been made. In comparison to the conventional pulling-through method, a rounded sample is pulled through a hole and the space between two horizontal plates. Various knitted fabrics have tested by this method and the force-displacement curves obtained analyzed.
