Análise visual dos danos causados em tecido de malha jersey pela perfuração de agulha da máquina galoneira

Abstract

The present work aims to visually analyze the damage caused by the inadequate use of needles during the finishing sewing process of jersey knit t-shirts. To achieve this objective, an experimental plan was developed simulating the manufacturing process of these items, allowing both qualitative and quantitative evaluation of the observed damage. The results demonstrated a direct influence of both needle point type and needle gauge on perforations and fiber ruptures, with gauge 16 needles presenting the largest visual damage areas and the highest level of fiber breakage. Additionally, although gauge 11 needles generated less visible damage, they resulted in a higher proportion of out-of-standard perforations according to statistical analysis. Therefore, the findings reinforce the need for careful selection of needles in the sewing process, contributing to defect reduction and improvement of quality control in jersey knit garment production.
