Cotton Covered Nylon-Core Yarns and Greige Fabrics

Abstract

Physical and mechanical properties of some specific cotton-rich, high tenacity, nylon- core yams and greige fabrics developed for military protective clothing are described. The core yams were produced on a modified ring spinning frame, and the fabrics were woven on a conventional dobby loom. The core yams and the fabrics developed from them contained approximately 70% cotton as cover and 30% high tenacity nylon filament as core. The core yams were about 25% stronger than comparable 70/30 cotton/nylon staple intimate blend or all-cotton yams, and the developmental greige fabrics were over 30% stronger. The developmental fabrics, after special finishing, may provide adequate flame retardancy as well as high strength retention. Properties of the finished fabrics will be reported separately.
