Study on the Influence of Tensional Properties on the Quality of Textile Materials
Abstract:
The problem of analyzing the quality of yarns and the structure of textile materialson the mechanical properties it is mainly in the following situations: in the technological manufacturing process after the textile product has been made or in the cutting phase, especially in the case of using yarns with increased elasticity or in the wearing process when the material is subjected to mechanical stress-strain. Most deformations due to the structure of the textile material make it more or less extensible and elastic in case of repeated mechanical stress. The ability of tex tile materials to deform under mechanical stress, especially tensile stress, is dependent on their elastic properties. Other factors that influence the deformation capacity of the textile material are represented by the gauges, stifness, contraction of the textile yarns. The study of the mechanical properties of textile structures under diferent strain rates is very important for the actual engineering design of the finished product. The elimination of latent stresses from the raw textile material is carried out during their finishing operations. It was found that the change in ten sile properties is due to the differences in the structure of the material, applying the same finishing process. It has also been demonstrated that the existing tensions in the textile material are completely eliminated after wearing, following complex stress. The paper presents the influence of tensional properties on the quality of textile materials and the interpretation of stress-strain diagrams through different mathematical models.
