  • Composite Alpaca yarn and process for making same
    Patent number: 7882687
    Abstract: Composite Alpaca yarn and a process for making same. The composite Alpaca yarn comprises special and unique characteristics created by blending long natural irregular Camelid fibers, such as Alpaca, with short synthetic fibers, or other natural fibers, in a combination determined by homogenization of fibers. The homogenization of fibers takes into account fiber lengths for twisting them with the use of high-pressure air blown nozzles, wherein Alpaca fiber is wrapped around an internal core. The face and surface of the composite Alpaca yarn, exhibit the fine characteristics of the Camelid fibers, including thermal isolation and impermeability, along with exceptional softness, wherein the Camelid fibers can be as fine as 18 microns.
