ANALYSIS OF THE FABRIC CHARACTERISTICS USING THE ANOVA MODEL

Abstract

In this paper, it’s analyzed the surface characteristics of woven fabrics. Of these features, the pilling effect is a typical pattern of flat textiles, which consists in forming, on their surface, of clusters of adherent fibers consisting of three types of fibers: outer ends (fibers with one end fixed in the base structure), outer loops (with both ends in the base structure) and marginal / wild fibers (fixed at least at one end) as a result of the action of the friction forces, affecting their appearance. Pilling is recognized as major aesthetic attribute of a woven apparel fabric. The study presents a new approach to the problem of objectively evaluating woven pilling by employing image analysis techniques and ANOVA (analysis of variance) model. The number of pills resulted on the fabric surface after abrasion testing and handle has been used as dependent, respective independent variables for ANOVA regression model. Processing of the testing results allowed an objective hierarchical classification of woolen woven materials according to their pilling resistance. Based on employed ANOVA model we have been established that there are significant differences between mean pills number depending on the handle (soft, cold or rough) of woolen fabrics. The results revealed that the formation of the pilling is characterized not only by the rate of formation and the ease of removal of the fiber agglomerations but also by the total and residual amplitude of the pilling.
