Abstract
Apparatuses and associated methods of manufacturing are described that provide for cut-resistant yarn structures. An example cut-resistant yarn structure includes a first cut-resistant core filament a second cut-resistant core filament. The yarn structure further includes a first covering yarn that is wound over the first cut-resistant core filament and the second cut-resistant core filament. The first covering yarn includes a core-spun yarn in which staple fibers are spun over a third cut-resistant core filament. The yarn structure also includes one or more covering layers wound over the first covering yarn that may serve as the exterior layer for the cut-resistant yarn structure. In some instances, the first and second cut-resistant core filaments include a core-spun yarn in which staple fibers are spun over the first cut-resistant core filament and/or the second cut-resistant core filament.
