Mechanical and Functional Attributes of a Tandem-Spun-Yarn-Fabric

A.P.S. Sawhney, L.B. Kimmel, M. Tyndall, P. Radhakrishnaiah


Properties of a woven, bottom-weight fabric made with the truly unique core-wrap yarns produced on Southern Regional Research Center's (SRRC) new Tandem Spinning System were examined. The mechanical properties such as tensile, tear, and bursting strengths were satisfactory. When appropriately heat set, without application of any sensitive chemical agent, the fabric exhibited satisfactory levels of durable press and dimensional stability, which were retained permanently even after subsequent wet processing including dyeing and repeated launderings. Flex abrasion resistance, pilling resistance, and air permeability of resin-finished fabric were also acceptable. The fabric had good hand and comfort attributes, as characterized by the Kawabata system. Subjectively, the fabric looked very interesting and was much softer than a typical 100% cotton, ring-spun-yarn fabric, apparently due to the excellent (yarn) core-coverage (about 95%) and the reversal of yarn twist direction in the core and wrap components, which, incidentally, is possible only in tandem spinning. This paper briefly describes the new, totally integrated, tandem spinning system and shows the properties of the fabric made with tandem spun yarns comprised of polyester-staple core (40%) and 100% cotton-wrap (60%).
