In this research, the performance properties of plain knitted fabrics made from open end recycled and virgin acrylic yarns are comparatively investigated, together with the effects of added covered and PBT elastic yarns. The previous studies about the recycling of textile wastes and their usage were mainly focussed on waste type including cotton fibre. Although acrylic textile wastes constitute one of the most common recycled waste types after cotton wastes, there have been no studies on the usage of this type of waste as a fabric form in the literature. The recycled acrylic yarn is spun from 100 % acrylic fibre wastes subjected to mechanical recycling process of garneting. Covered and PBT elastic yarns are incorporated to give an added value to the recycled acrylic fabrics. The experimental and statistical results reveal that the fibre type (acrylic waste fibre and virgin acrylic fibre) and the elastic yarn state (addition and type) parameters affect all the performance properties of the fabrics significantly. The recycled acrylic fabrics exhibit higher thickness, pilling tendency, abrasion resistance and coursewise extension results and lower bursting strength results than the corresponding virgin acrylic fabrics. As far as the elastic yarn state is considered, it is observed that the fabrics with the covered yarn reveal the highest stitch density, mass, thickness and walewise extension results, followed by the fabrics with the PBT yarn. The highest bursting strength and the lowest pilling tendency results are obtained for the fabrics with the PBT yarn. Addition of the elastic yarn improves the abrasion resistance of the recycled and virgin acrylic fabrics. No statistically significant difference is found between the abrasion results of the recycled acrylic fabrics with the covered yarn and the PBT yarn.

在这项研究中，比较研究了由开端再生纱和腈纶原纱制成的平针织物的性能特性，以及添加包覆弹力纱和 PBT 弹力纱的影响。以往关于纺织废料回收利用的研究主要集中在包括棉纤维在内的废料类型。尽管腈纶纺织废料是继棉花废料之后最常见的回收废料类型之一，但文献中还没有关于将此类废料用作织物形式的研究。再生腈纶纱线由 100% 腈纶纤维废料经石榴石机械回收工艺纺制而成。包覆层和 PBT 弹性纱线的加入为回收的腈纶织物提供了附加值。实验和统计结果表明，纤维类型（腈纶废纤维和腈纶原生纤维）和弹力纱状态（添加和类型）参数显着影响织物的所有性能特性。与相应的原始腈纶织物相比，回收的腈纶织物具有更高的厚度、起球倾向、耐磨性和横向延伸结果以及更低的爆破强度结果。就弹性纱线状态而言，观察到包覆纱线的织物显示出最高的针迹密度、质量、厚度和纵行延伸结果，其次是带有 PBT 纱线的织物。使用 PBT 纱线的织物可获得最高的破裂强度和最低的起球倾向结果。弹性纱的加入提高了再生和原生腈纶织物的耐磨性。使用包覆纱和PBT纱的再生腈纶织物的磨损结果在统计上没有显着差异。
