ABSTRACT
Three different woven fabrics made from yarns type wool have been studied regarding pilling resistenace. Impact of number of abrasion cycles and pressure force on surface characteristic was studied. The experiemental data were analyzed by multifactorial analysis of variance (ANOVA). Pilling is a typical manifestation of plane textiles, which consists in formation on textiles surface, of some fiber agglomerations as result of friction forces action. The experimental work was carried out in lab condition, on samples designed by specimen device and subjected to homogeneous friction on one side. Differentiation of woven fabrics depending of surface characteristic, respective handle (soft, rough, cold) was established by determining the number of agglomeration formed and detached/unit area or unit mass. So, it has been made a quantitative and qualitative analysis of those three groups of woven fabrics.Mathematical modeling is an investigation method of technological processes based on experimental data collection and processing, processing used in computer simulation of these processes. It was established, after mathematical modeling, that exists significant differences between the mean values of fiber agglomerations number of woven fabrics analyzed and having soft, rough or cold handle. These models, in relation with the factors that influenced the taking of the decision, permits the optimal conditions finding of action in a shorter time and less material expenses then on lab researches way, obtaining quality products with minimal costs.
