Abstract
An insulating fill material composition for use in outerwear, sleeping bags, bedding, and the like includes 40.0 to 85.0 wt % alpaca fibers, 10.0 to 20.0 wt % bicomponent fibers, and 5.0 to 40.0 wt % polyester fibers. The alpaca fibers have a length of 40.0 to 70.0 mm. The bicomponent fibers have a length of 40.0 mm to 60.0 mm and a linear mass density of 0.11 to 0.33 mg/m. The polyester fibers have a length of 40.0 mm to 60.0 mm and a linear mass density of 0.22 to 0.44 mg/m. Blending, combing, carding, and lapping of the alpaca fibers, the bicomponent fibers, and the polyester fibers forms a matte, which when needled and heated forms a batting having a weight of 50.0 to 400.0 g/m2.
