Abstract: A method and system for forming composite yarns having selected performance characteristics including cut resistance and/or fire/heat resistance. The composite yarn will include a core of one or more filaments and a fiber bundle wrapped about the core and integrated with one or more additional filaments that help bind the fibers about the core. An additional filament or other composite yarn can be plied together therewith to form the finished composite yarn. The core filament(s) will be selected from cut and/or fire/heat resistant materials, while the fibers of the fiber bundle and the additional filament(s) wrapped about the core can be selected from natural or synthetic fibers or filaments having additional desired properties.

Abstract: A method and system for forming fire and abrasion resistant yarns is disclosed. The fire and abrasion resistant yarn includes a fibrous bundle spun from a blend of fire retardant fibers and non-fire retardant fibers. The fibrous bundle is wrapped and integrated with a filament comprising a fire retardant (FR) material, and which is introduced during spinning of the fibers of the fibrous bundle so as to be wrapped about and help bind the fibrous bundle. The FR filament will be selected from fire/heat resistant and abrasion resistant materials, while the fibers of the fibrous bundle can be selected from natural or synthetic fibers or filaments having additional desired properties.

Abstract: A method and system for forming protective composite yarns and fabrics having selected performance characteristics including cut resistance and/or fire/heat resistance, while also providing enhanced comfort and aesthetic attributes. The yarn will include fibers of a first type introduced from a first roving to a first set of drafting rollers of a spinning frame, and one or more additional types of fibers introduced from one or more additional rovings additional sets of drafting rollers of the spinning frame in an alternating fashion with the fibers of the first type.
