A model that describes the fracture behavior of air-jet spun yarns is proposed. The failure mechanism of wrapper and core fibers is described, and an expression for com puting total yarn strength is derived. The effects of structural parameters and fiber properties on the strength of air-jet spun yarns are discussed, and the limitations of the model are analyzed.
