Fibers comprising protein and polymer components, methods of use, methods of manufacture, and related threads, yarns, textiles, and fabrics thereof

Abstract

In an embodiment, yarn comprising a plurality of fibers is provided. Each fiber may include at least 0.5% protein by weight and a synthetic polymer. Each of the plurality of fibers may be a melt-spun fiber. For each fiber, an outer portion may have a higher density of protein particles than an inner portion. Each fiber may be a skin-core fiber comprising an inner core and an outer sheath. The outer sheath of each of fiber may include at least 1% protein by weight. The inner core of each fiber may include less than 1% and/or less than 0.1% protein by weight. In another embodiment, a fabric woven from the yarn is provided. The fabric may have no or negligible discernable scroop. In other embodiments, methods of manufacture are provided.
