Abstract

The use of recycled materials has become increasingly important in both the textile and apparel industry. Recycling means the breakdown of raw materials from existing products and the re-use of the as-obtained raw material in a new product. Many fibers including cotton, wool, nylon, and even aramids are recycled and are re-used in yarn manufacturing, but polyester is especially the most common fiber used for this purpose. The bursting strength properties of knitted fabrics, having blend yarns at different yarn numbers that contain recycled polyester fiber, were researched in this study. For this purpose, blend yarns containing viscose fiber and recycled polyester (rPET) fiber at different blend ratios, and pure yarns with virgin polyester fiber were produced, and after that, these yarns were knitted. The study results revealed that the rPET fibers provided the bursting strength values which are close to that of virgin PET fibers for the knitted fabrics having coarse yarns, whereas they do not contribute positively to the knitted fabrics having fine yarns. Thus, it is once more proved that the use of rPET fiber is more suitable for the knitted fabrics containing coarse yarns, and it is not definitely proper for the ones having Ne 40 yarns.

摘要

回收材料的使用在纺织和服装行业变得越来越重要。回收是指从现有产品中分解原材料，并将获得的原材料重新用于新产品中。许多纤维，包括棉花、羊毛、尼龙，甚至芳纶，都会被回收并重新用于纱线制造，但聚酯是用于此目的的最常见纤维。本研究研究了针织物的爆破强度特性，该织物具有不同纱线数的混纺纱，其中含有再生聚酯纤维。为此，生产了含有不同混纺比例的粘胶纤维和再生涤纶（rPET）纤维的混纺纱，以及含有原生涤纶纤维的纯纱，然后将这些纱线编织在一起。研究结果表明，rPET 纤维为粗纱针织物提供了接近原始 PET 纤维的破裂强度值，而它们对具有细纱的针织物没有积极贡献。因此，再次证明了rPET纤维更适合用于含有粗纱的针织物，而对于含有Ne 40纱的针织物则不一定合适。
