Abstract
An exemplary down and fiber blend may comprise a first weight of down having a water-resistant coating applied thereto, and a second weight of water-resistant fiber. The water-resistant treated down is preferably dried prior to mixing with the chosen fiber. The fiber in the blend may preferably be a polyester fiber, such as a polyester staple microfiber. A method of forming a down and fiber blend may include the gradual introduction of the fiber into a mixing box in which the water-resistant treated down is being stirred. Fiber and mixing parameters are also provided which have been determined to result in optimal performance characteristics of the fiber blend. In the microfiber blend embodiments, each strand may preferably have 6 to 9 crimps per inch, and the microfiber strands may preferably be 0.8 to 1.4 denier.
