This research is focused on hollow polyethylene terephthalate (PET) fibers and fabrics. The aim of hollow section fibers application is a textile contribution to weight reduction of the whole vehicle. CO₂ emissions consequences and awareness of companies to environmental issues are driving studies on the direction of vehicle weight reduction, according to recent European regulations. For this purpose, fabrics composed of hollow fibers have been produced and characterized. In order to be applied as seats covers for the automotive sector, they have been compared to current production woven fabrics. Tensile, tear strength tests and aesthetic and structural abrasion have been carried out. The performance of hollow fibers PET fabrics is slightly lower than full section fabrics, but completely acceptable according to automotive requirements. Its specific application can be evaluated.

这项研究的重点是中空聚对苯二甲酸乙二醇酯（PET）纤维和织物。中空截面纤维应用的目的是纺织品有助于减轻整车的重量。一氧化碳₂根据最近的欧洲法规，排放后果和公司对环境问题的意识正在推动汽车减重方向的研究。为此目的，已经生产并表征了由中空纤维组成的织物。为了用作汽车领域的座套，已将它们与当前生产的机织织物进行了比较。已经进行了拉伸，撕裂强度测试以及美学和结构磨损。中空纤维PET织物的性能略低于全幅织物，但根据汽车要求完全可以接受。可以评估其特定的应用程序。
