Statistical Analysis of the Pilling Behaviour of Polyester/Cotton and Polyester/Viscose Blended Woven Fabrics

Abstract

In this work, the pilling behaviour of polyester blended fabrics was studied and analysed statistically. Two different groups of blends were selected, namely polyester/cotton (P/C) and polyester/viscose blends (P/V). All the fabrics were assessed for pilling performance using ICI pill box, and two-way ANOVA was conducted to analyse the effect of the number of revolutions and type of fibres on the pilling behaviour of the fabrics. The analysis was further narrowed down by conducting a series of ANOVA, by segregating the number of revolutions into two stages and blend proportions into three stages for group I fabrics. Similarly for group II fabrics, both the, number of revolutions and blend proportions were segregated into two stages each. It was found that the type of component fibre used to produce the fabric loses its significance as the number of revolutions increases.
