Abstract: Composite fibers having a structure comprising a core component and sheath component, wherein each of the core component and the sheath component independently include a polymer and a disclosed cooling composition. In various further aspects, this application pertains to single-covered yarn including a core yarn comprising a disclosed composite fiber including a core component and a sheath component, and a first fiber including a cellulosic fiber, such that the first fiber is wrapped or surrounds the core fiber. In still further aspects, this application pertains to a woven or knit fabric including a disclosed single-covered yarn.

Abstract: The subject disclosure can facilitate piezoelectrics for energy harvesting. In one example, an article of manufacture (AOM) is provided. The AOM can comprise a piezoelectric fabric comprising: a piezoelectric film; an elastic base on which the piezoelectric film is bonded forming a piezoelectric material; and a yarn, wherein the yarn and the piezoelectric material are coupled to one another in a defined ratio of interlacement. The yarn and the piezoelectric material are configured as coils in some embodiments. In some embodiments, the piezoelectric material is configured such that compression or elongation of the piezoelectric material generates electrical energy. In some embodiments, the AOM further comprises a power management module coupled to the piezoelectric material and configured to store electrical energy received from the piezoelectric material. The AOM can also comprise a rivet, grommet or button coupled to the piezoelectric material or the power management module and configured to capture energy.

Abstract: In one aspect, the disclosure relates to composite yarns having a structure comprising a core component and sheath layer, wherein each of the core component and the sheath layer independently comprise a polymer and a disclosed cooling composition. In various further aspects, the present disclosure pertains to double covered yarns comprising an elastic core comprising an elastic core; a first yarn in contact with the elastic core, and wherein the first yarn comprises a disclosed yarn comprising a core component and a sheath layer; and a second yarn in contact with the first yarn, and wherein the second yarn comprises a yarn comprising a cellulosic fiber. In still further aspects, the present disclosure pertains to a fabric, such as a denim fabric.
