Properties of knit fabrics made from recycled cotton/ r-PET blended yarns

In this study, open-end spun yarns have been produced from recycled cotton fibres by blending with r-PET fibres in three blend ratios (80/20, 70/30, and 60/40). The linear density of the yarn is maintained at 20Ne. Tensile strength, elongation at break, unevenness (CVm%), and hairiness of the produced yarns have been measured. It is found that the yarn manufactured with 60/40 recycled cotton/r-PET blend ratio has better yarn quality index value as compared to other blend ratios. The single jersey fabric has been developed from the 60/40 recycled cotton/r-PET yarn. Bursting strength, pilling resistance, and dimensional stability of the developed fabric are studied and compared with the commercial fabric. It is found that the properties of the developed fabric are comparable with commercial fabric and can be used to produce knit top garments, such as T-shirts and polo shirts.
